Improvements in and relating to Machines for Making Type Bars.
I, CHARLES JUNGE, of Lincoln Chambers, 75, Chancery Lane, London, W.C.,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
The invention relates to the class of machines in which independent matrices,
which are stored in magazines, are selected and released by the operation of
finger keys, are assembled in line in the order in which they are released, a type
bar is cast, from said assembled matrix line, and the matrices are automatically
distributed to their respective magazines.
The invention relates particularly to the escapement by which the independent
matrices are upheld and released; to the shift mechanism by which the depression
of one escapement key may be caused to operate either of several escapements;
to the mechanism for assembling the matrices in line, and for moving the
assembled line to the casting mechanism; to the mechanism concerned in the
casting of the type bar; to the elevator mechanism for conveying the matrices
from the casting mechanism to the distributing mechanism; to the mechanism
for distributing the matrices; to the construction of the matrices themselves,
and to the combination; with the several mechanisms, of electro-magnets and
electrical switches, by the operation of which the movement of the several
mechanisms is produced, or initiated and continued until they have performed
their several functions.
The two principal members of the frame are a bed and an upright member
which is secured to the top of the bed. On the front side of the upright member
are formed, first, the magazines, which are vertical channels in which the matrices
are stored when not in use; second, the assembling channels, which lie beneath
and in open communication with the lower ends of the magazines, which assem
bling channels converge and are merged together, forming, finally, a single
channel which is called the assembling spout; and, third, the distributing chan-
nels, which lie above the open ends of the magazines.
The distributing
channels converge from their lower ends upward, being successively merged
together until, at the extreme upper end of the distributing system, all of the
channels have been merged together to form one channel, which is called the
distributing spout. Or, to describe the distributing system in other language,-
it is made up of channels which diverge from a single channel at the top,-
which channels are repeatedly subdivided by diverging partitions, each of which
divides a channel into two channels, until there are formed as many distributing
channels as there are magazines; and these channels are in open communication
with the several magazines. At the upper end of each of each of the dividing parti-
tions, a gate or switch is placed, whereby either of the branches formed by said

page_text: partition may be placed into communication with the channel of which it is a
branch.
The vertical magazines are either cut into the front face of the upright member
or are formed by securing to the face a number of vertical partitions. These
magazine channels are of such size that the matrices lie therein, edge foremost,
the bottom of each matrix resting on the top of that one next below it,-and
the lowest matrix in each magazine being supported upon a part of the escape-
ment, by means of which said matrices are released singly.
A plate, preferably made of glass, is secured over the front of the magazines
and assembling and distributing channels, thereby enclosing them.
Supported on the bed, with its right end just below the assembling spout,
is the assembling trough, and the matrices when released from their magazines
fall through said spout into this trough. The left end of this trough is at a
point where the matrices may be delivered therefrom to the casting mechanism.
While any form of casting mechanism may be employed for the purpose of
casting a type bar from the assembled matrix line, the preferable construction
includes a cylindrical mold block having a recess which receives the assembled
line of matrices, and containing a clamping block by which the matrices are
forced into contact with that wall of the muld block through which is formed
the type slot, or opening, into which the molten metal is injected to form the
type bar, the line of characters on the mold being directly in line with said slot.
An elevator is supported on suitable guides at the left side of the machine.
It is movable by suitable mechanism from a position in line with the discharge
opening of the mold to a position in line with the elevator distributing trough.
Matrices are pushed out of the mold onto the elevator after the type bar has
been cast, and, by the elevator, are carried up to the distributing trough. They
are pushed onto this trough and along the same until they are permitted to drop
one by one through an opening in the bottom of the trough into the upper end
of the distributing system, or into what has been heretofore called the distri-
buting spout.
In the machine as organized a number of electro-magnets are employed to
actuate different parts of the mechanism. Normally these magnets are inert,
because the several electric circuits of the magnets are broken in one or more
places. Means are provided for automatically closing the breaks in said circuits
at the proper times and holding them closed long enough for the magnets to
perform their functions. The electrical current for the magnets is supplied by
any suitable generator. One wire of the generator is preferably connected with
the metallic frame work of the machine by means of a suitable switch; and
the other wire is connected with one or two central stations or depots, as they
are generally called. These depots are insulated pieces of metal which are placed
conveniently with respect to the magnets. Any magnetic circuit is complete
when one wire thereof is electrically connected with the metal of the machine,-
and the other with one or the other of said depots. These depots are employed
instead of connecting each magnet with the generator, for convenience in wiring,
and for no other reason.
The driving mechanism for the different parts of the machine are for the most
part supported from the under side of the bed,-the prime mover being an
electric motor. The bed is preferably hinged to a box, like a cover thereto,
whereby all of the parts which are suspended from the under side of the bed are
normally concealed and protected. When any of said parts need adjustment
or repairing, the bed may be swung back on its hinges, thereby exposing said
parts.
The escapement for retaining the matrices in each magazine and releasing
them singly therefrom, consists preferably of two slides and their operating
mechanism. Each slide is moved forward and backward in a horizontal slot
through the upright frame member, the distance between the upper edges of
said slides being substantially equal to the height of the matrices used. The
forward ends of these slides are adapted to project into the associated magazine;

page_text: the rear ends of said slides are operatively connected with the ends of a substan-
tially vertical lever, whereby, when said lever is rocked, the two slides are moved
in opposite directions, that is to say, when one slide is moved so that its forward
end enters the magazine, the other slide is withdrawn therefrom. When the
parts are at rest, the lower slide projects into the magazine and all of the matrices
therein are sustained by it. On the rear side of each of the vertical levers is
a substantially horizontal arm, which is adapted to be moved up and down by a
vertically movable rod. This rod is connected at its lower end with one of the
key levers and is operated thereby. When a key lever is depressed, the corre-
sponding vertically movable rod is moved upward against one of the horizontal
arms referred to, thereby operating the vertical lever so that the upper slide
is moved forward until its end projects into the magazine beneath the next to
the lowest matrix. The lower slide is drawn backward at the same time and is
withdrawn from said magazine just after the upper slide enters it, whereupon
the lowest matrix drops out of the magazine. The upper rear edge of each
matrix is cut off or bevelled, and the forward end of the slide is bevelled to a
point so as to facilitate the described movement of said slide beneath the next
to the lowest matrix. When permitted to so move, the lever for operating these
slides is moved in the reverse direction by a spring, and consequently the lower
slide is moved into the magazine and the upper slide is withdrawn, whereby all
of the matrices move down until the lowest matrix rests upon said slide.
Two slides and their operating lever, like that just described, are provided for
each magazine; but the upper ends of the vertically movable rods may be moved
to the right or left of their normal position, so that they may operate either
of three adjacent levers. The shift mechanism with which each rod is so moved,
consists of a transversely movable horizontal bar, through which the upper ends
of the rods pass loosely, which bar is suitably supported; it may be moved to
the right or left a distance equal to the distance between two of the slide
operating levers by two shift keys and suitable connecting mechanism. By
means of this shift mechanism, only one-third as many keys are needed as would
be required if each escapement required a separate key.
The assembling trough is located beneath the assembling spout and extends
therefrom to the left to the casting mechanism.
The machine as organized is designed to produce the type bar in the same
machine which assembles the matrices, wherefore the assembling trough leads,
as stated, to the casting mechanism. If, however, it should be desirable to
remove the assembled matrices to an independent casting machine, the trough
may be extended to any convenient point.
As each matrix drops from the assembling spout into the assembling trough,
it must be moved from beneath said spout to make room for the next matrix.
To secure this result, a horizontally movable plunger is provided which projects
into the right end of the spout. When at rest this plunger lies just to the right
of the assembling spout; but immediately after each matrix falls into the trough,
the plunger makes a quick movement to the left, pushing the matrix before it,
until said matrix passes certain retaining pawls which prevent it from moving
backward. The plunger is operated after the fall of each matrix by an electro-
magnet, the circuit of which is completed by the matrix as it falls into the
assembling trough. The plunger is of course connected with the armature of
the magnet. One wire of the magnet is connected with one of the depots before
referred to; the other is connected with an insulated contact piece. A flexible
spring which is electrically connected with the metal of the machine, lies just
beneath the assembling spout, and the matrices as they fall into the trough fall upon
this spring, which is pressed down into contact with said contact piece, thereby
completing the circuit of the magnet, which, as before stated, causes the plunger.
to move to the left, thereby pushing the matrix along the assembling trough
and off of said spring. The circuit of the magnet is thus broken, and a suitable
spring withdraws the plunger to its normal position.

page_text: In order to hold the matrices in a compact line and to prevent them from
falling over, a detent projects into the trough through a slot in the bottom,
which slot begins just to the left of the assembling spout. The detent is subject
to the action of a spring which tends to move it to the right to a point just
to the left of the assembling spout. The detent is the upturned end of an arm
which is rigidly secured to a rod. This rod is movable endwise in suitable
bearings, and it is likewise susceptible of a small oscillatory movement on its
own axis, by means of which the detent may be withdrawn from the assembling
trough. A spring acts to draw the detent rod to the right. The spring is
likewise connected with the detent rod in such manner that it exerts a force
tending to turn said rod upon its axis, and move the detent up into the trough,
after it has been moved out of the trough by suitable mechanism and for the
purpose to be presently explained. In the end of the detent is a spring pawl,
which, when the detent is moved down out of the trough automatically flies
beneath the front edge of the slot in the bottom of the trough and holds the
detent down until the pawl is pushed out of engagement with said trough. This
last named movement of the pawl is effected after the detent has been drawn to
the right to its normal position. It is moved back to this position by the
spring, said spring pawl preventing it from entering the trough; and when
it reaches this position the pawl is disengaged and the detent swings up into
the trough ready to act as before described.
A claw is secured to a rod, which rod is mounted in bearings in which it is
both longitudinally and axially movable. A spring is connected with the rod
in such manner that when the rod is moved to the right, the spring is com-
pressed, and when the rod is moved axially, the spring is twisted. When the
claw and the claw rod are in their normal positions, to which the spring tends
to move them, the claw is out of and behind the trough and in a vertical plane
to the left of the assembling spout. When the assembling of a matrix line is
completed, the claw is moved into the trough, the claw rod turning in its
bearings, and the matrix line is pushed by the claw to the left to a position
to be engaged by a push device to be presently explained. This claw is moved as
described, by the operator; and as the claw is moved toward the left, it pushes
the matrix line ahead of it until a certain point is reached where a pawl falls
behind the claw and for the time being prevents its backward movement. When
the matrix line lies between the detent and the claw, in the position last above
described, it may be justified by manually inserting the proper spacers.
When the line has been justified, it is moved along the assembling trough
into the mold, which is placed at the end of said trough, by means of a device
which I call the push. The push is an arm secured to a rod which is movable
both longitudinally and axially; it normally lies outside of the assembling
trough. A spring resists the movement of this rod to the left, and also resists
such a movement of the rod upon its axis as necessarily takes place when the
push is moved into the assembling trough; consequently this spring tends to
return the rod to its normal position, when permitted to so act. A rack is
formed on the push rod and a pinion engages with said rack. This pinion is
normally loosely mounted upon a vertical shaft, which shaft is constantly
rotated. A clutch is provided for connecting the pinion to the shaft, and this
clutch is operated by an electro-magnet, the circuit of which is completed by
a switch; and this switch is operated when the push is moved down into the
assembling trough. The clutch operating mechanism is connected with the
armature of this magnet, and when the magnet is energized by the completion
of its circuit, the clutch is thrown in and the pinion revolves, with the result
of moving the push rod to the left, whereby the assembled line of matrices is
pushed into the mold. The movement of the push into the assembling trough
causes the withdrawal of the detent and claw from said trough, whereupon said
parts are moved back to their normal positions by their springs, before described.

page_text: When the push has been once moved into the assembling trough, it cannot
be moved out of said trough until it has completed its intended movement.
While various forms of casting mechanism may be employed, satisfactory
results are obtained by employing a cylindrical mold which is adapted to
oscillate upon its axis in a suitable socket between clamping jaws. A longi-
tudinal opening or recess extends through this mold from end to end. This
recess contains a movable matrix clamp.
A type slot, the exact size of the type bar which it is desired to form, extends
radially through the wall of the mold and into the recess which receives the
matrix line. A matrix clamp moves the matrix line and holds it firmly against
that side of the mold recess through which said slot passes, and with the characters
on the matrices directly in line with said slot. Doors are provided for closing
the ends of the mold after the matrix line has been moved into the mold recess,
and for holding the matrices in close contact with one another. When these
doors have been closed, the mold is rotated about one quarter of a revolution,
the matrix clamp is operated during this revolution and the mold stops with
the slot directly below the nozzle through which molten metal may be forced.
This nozzle is formed on the lower end of a box containing a pump and the
melting pot, and its lower surface fits tightly against the surface of the mold.
The sockets in which the mold revolves are on the top of the bed plate.
Suspended from the under side of the bed plate is the mechanism for moving
the mold and the matrix clamp, and for closing the doors of the mold.
These various operating mechanisms are set in motion by friction clutches
operated by clectro-magnets,-the circuits of which are closed and broken in
proper sequence.
After molten metal has been injected into the mold slot, the mold is returned
to its original position, the end doors are opened, and the push begins a second
movement to the left which pushes the type bar out into a suitable galley, and
pushes the matrix line onto an elevator, by means of which said matrices are
carried up to the distributing mechanism.
The elevator is provided with a trough which receives the matrices,-which
trough is in line with the opening of the mold when the elevator is at its lowest
position. The elevator is a more or less heavy block of metal, through which
passes two fixed vertical guide rods. A sprocket chain is secured to the elevator,
and this sprocket chain runs over sprocket wheels, one placed above the distri-
buting trough and one below the level of the mold recess. This lower sprocket
wheel has not, under normal conditions, any operative connection with the power
shaft or prime mover; but after the matrices have been pushed onto the trough
which the elevator carries, this lower sprocket wheel is, by the operation of
a friction clutch, connected with the prime mover and is compelled to rotate.
This friction clutch is operated as before, by an electro-magnet, the circuit
of which is completed when the matrices have passed on to the elevator. The
rotation of this lower sprocket causes the elevator to be raised.
The distributing trough is secured to and extends horizontally across the
upper end of the upright frame member. In its bottom is an opening directly
over the distributing spout, through which the matrices drop one by one.
Extending horizontally across the machine, above the distributing trough, are
two guide rods on which a propeller is mounted so as to be movable across the
machine. The propeller is connected with the lower leg of a sprocket chain
which runs over two sprocket wheels which are loosely mounted on properly
placed horizontal shafts. The propeller is operated by a rack which is vertically
movable in suitable guides on the face of the upright frame member. This
rack engages with a pinion which is rigidly connected with the left sprocket
wheel associated with the propeller. When this rack is raised it revolves said
pinion and the sprocket wheel, with the result of drawing the propeller to the
left until it reaches a position at the left of the vertical path of the elevator.
This rack is moved up by the elevator which engages with an arm projecting

page_text: from the rack slide. When the rack has been moved up a sufficient distance,
this arm is tripped, whereupon the rack falls by gravity, the result being that
the sprocket is rotated in the contrary direction and the propeller is thereby
moved to the right. This arm is tripped and the rack allowed to fall just as
the elevator reaches a position in which the elevator shelf on which the matrix
line is sustained, is in line with the distributing trough. As the propeller moves
to the right, it pushes this matrix line out of the elevator trough and into the
distributing trough as far as that line can go at that time.
In the bottom of the distributing trough and directly over the distributing
spout, there is an opening through which the matrices may fall one by one for
distribution. As before stated, just below the distributing spout are the
diverging distributing channels which are successively doubled in number in
obliquely placed partitions. These partitions lie at an angle, diverging from
the top downwards. At the upper end of each partition a switch is pivoted to
the upright frame member, whereby by moving said switch the channel on
either side of said partition may be placed in communication with the channel
which said partition divides. The sub-division of the distributing channels by
diverging partitions from top to bottom is repeated until there are as many
channels as there are magazines.
The switches are arranged in rows and the number of switches in the rows
necessarily increases from the upper end downward. Each switch is rigidly
secured to a short shaft which shaft passes through the upright frame member
in which it is journalled. A crank arm is rigidly secured to the rear end of
each switch shaft. All of the crank arms which are connected with the switch
shafts in each row are pivotally connected with a bridge bar.
From the foregoing statement it is clear that when any switch is moved, all
of the other switches in the same row must be moved at the same time and in
the same direction. One switch shaft in each row has secured to it an operating
crank arm, and these arms are severally connected by means of links with the
armature of an electro-magnet,--there being of course as many electro-magnets thus
connected as there are rows of switches. Normally all of the switches are swung
to the left, being so moved and held by the several armatures with which they
are connected, said armatures being moved away from the poles of the magnets
by springs. It is clear that by turning the proper row or rows of switches, an
unobstructed channel is formed connecting any desired magazine with the distri-
buting spout.
In the distributing trough, near the right end thereof, is a sliding block, which
I call the gate keeper; passing horizontally through it from left to right are as
many insulating metallic pins as there are rows of switches and magnets for
operating them. Seven of these pins are employed, and seven rows of switches
and operating magnets. These pins are susceptible of a slight longitudinal move-
ment, and they are forced forward in the gate keeper, that is to the left, by
spring wires which severally connect them with the switch operating magnets.
This provision for moving the pins is made to insure that all of the pins may
be brought into metallic contact with the matrices which are intended to touch
them. Secured to the bottom of the gate keeper is a gate, which, when the
gate keeper is at the left of its path, covers the opening in the bottom of the dis-
tributing trough above the distributing spout. Two bars extend across the dis-
tributing trough, just to the right end of the opening in the bottom thereof
above referred to. The purpose of these bars is to prevent the matrices from
moving to the right beyond said opening, following the gate keeper.
The gate keeper is moved backward and forward by a toggle, one end of which
is pivoted to the said gate keeper, and the other to a fixed point. The toggle
joint is connected by means of a link with the armature of an electro-magnet.
When the circuit of the magnet is complete, the toggle is flexed, thereby drawing
the gate keeper to the right, thus withdrawing the gate from the opening in
the distributing trough, so that the matrix which is above said opening may

page_text: fall through it into the distributing spout. When the circuit of the magnet is
broken, the armature thereof is retracted by a spring, the toggle is straightened,
and the gate keeper moved to its original and normal position.
In order to prevent any matrix except the right hand matrix from falling
through the opening in the distributing trough, a device is employed which is
called a pinch, which impinges against the next matrix and holds it immovable
while the first matrix is falling. This pinch is a curved arm rigidly secured to
a rock shaft, which rock shaft is mounted in bearings secured to the distributing
trough. Two operating arms are likewise secured to the rock shaft, and each
arm is connected by a link with the armature of an independent electro-magnet.
The matrices are small rectangular pieces of metal, each having the character
depression in its rear edge. One or more transverse holes are made for each
matrix, said holes being placed in any one of the seven positions corresponding
to the positions of the seven pins carried by the gate keeper. The purpose of
these holes is to prevent the matrix, when it is moved against the pins, from
completing the magnetic circuits in which these pins are connected, which
directly face the holes,-the holes being large enough for the pins to enter them
without coming in contact with the matrix. It is apparent that there may be
many different combinations and arrangements of said holes in said matrices,-
and, in point of fact, the machine contains as many different kinds of matrices
with reference to the arrangement of said holes, as there are magazines. The
matrices necessarily vary in thickness in their body parts, that is to say, in the
parts in which the character depression is formed, in accordance with the width
of said characters;-but the parts of all of said matrices through which said
holes are formed are of the same thickness, the right side of the matrices being
cut away to produce this result. This right side is the side which is moved
against the pins carried by the gate keeper. The matrices are thus cut away
as described to make them of equal thicknesses around the holes. When any
matrix is in contact with the pins carried by the gate keeper, the next matrix
will be in position to be engaged by the pinch.
As previously stated, the circuits of the various electro-magnets are normally
incomplete, but are severally completed when one pole thereof is electrically con-
nected with the metallic frame of the machine, and the other pole is electrically
connected with one of the depots. The circuits of all of the magnets are
incomplete because one or more breaks are made therein, either between the
magnets and the depot, or between the magnet and the machine, or both.
Mechanism is provided for automatically closing these breaks at the proper time
and thereby energizing the several magnets.
Magnets which operate the several rows of switches have similar electrical
connections. One wire of each magnet is connected with a depot, the other
wires of the several magnets are severally connected with the pins carried by
the gate keeper. The circuits of these several magnets are completed by the
matrices themselves in the following manner: The propeller before explained
pushes the row of matrices to the right, causing the right hand matrix to move
into contact with so many of the pins carried by the gate keeper as it is adapted
to contact with. The matrix, being in contact with the metallic part of the
machine, completes the circuits of the magnets corresponding with the said pins
which the matrix touches; for example, if a matrix having four holes is moved
into contact with the gate keeper's pins, said matrix will consequently not
contact with four of the pins, but will contact with the other three pins; the
circuits of the three corresponding magnets will be completed, with the result
of swinging the three corresponding rows of switches.
Were this connection made by the matrix the only one made for said magnets,
said connection would be broken as soon as the matrix dropped away from said
pins into the distributing spout, and, as the result, the switches might swing
back to their normal position before the matrix had reached its proper magazine.
To prevent this action the same wire of the magnets which is electrically con-

page_text: nected with the pins carried by the gate keeper is likewise connected with a
number of insulated springs.
The armature of each of the switch magnets carries a finger which, when said
armature is attracted by the magnet, is brought into contact with the correspond-
ing spring, and this makes a second contact with the machine, because said
armatures are electrically connected with the machine. This last named contact
is broken by means of a device called a switch-back, which is a pivoted bar which
extends over said insulated springs, and has insulated pieces which are adapted
to contact with said springs. This switch-back is operated by an electro-magnet,
which moves the switch-back and withdraws the said springs from contact with
the fingers carried by the armatures of the switch magnets, which breaks the
circuits of all of said magnets, whereupon the switches return to their normal
position. The circuit of the magnet which operates the switch-back is normally
broken, but is temporarily completed when the gate keeper moves to the right.
One wire of pinch magnet No. 1 is connected with a depot, and the other
wire with a metallic bar carried by but insulated from the switch-back. This
bar carries a number of springs so placed that the fingers carried by the armatures
of the switch actuating magnets will contact with them at the same time they
contact with the other spring. This magnet is energized and the pinch caused
to operate as soon as the switch gates are operated; and its circuit is broken
at the same instant the circuits of the switch magnets are broken, and by the
same means, namely, the switch back.
One wire of pinch magnet No. 2 is connected with a depot, and the other wire
with a spring which is so placed that it will contact with the gate keeper toggle
when the same is flexed to move the gate keeper to the right; and this contact
is not broken until said gate keeper has nearly returned to its normal position.
From the foregoing statement it will be understood that the circuits of the
various magnets are completed and broken automatically at such times and in
such sequence that the various parts operate as follows: When a matrix contacts
with the pins carried by the gate keeper, the circuits of the proper switch
operating magnets are completed: their armatures are moved, thereby making
a second connection for said circuits, and at the same time completing the circuit
of pinch magnet No. 1. The proper switches are thereby operated, and are held
in the proper position until the matrix has entered its magazine. The matrix
next to the right end matrix is meanwhile grasped and held by the pinch. The
movement of the No. 1 pinch magnet armature causes the circuit of the gate
keeper magnet to be completed, whereupon the gate keeper moves to the right
to uncover the opening in the distributing trough through which the matrix is
to fall. The circuit of the pinch magnet No. 2 is completed while the gate
keeper is moving to the right. Directly after the gate keeper has moved far
enough to the right to allow the matrix to drop, the circuit of the switch back
magnet is completed. The operation of the armature of this magnet breaks
the circuit of all of the magnets except pinch magnet No. 2. The gate keeper
begins its return movement, thereby first breaking the circuit of the switch-back
magnet, and finally breaking the circuit of pinch magnet No. 2. The magnets
and parts operated thereby are now in their original position. The propeller
moves the matrix line to the right, the end matrix strikes the pins and these
actions are repeated.
While this matrix line is being distributed, another matrix line will have been
assembled and moved into the mold, and the mold will have been turned so
that the type slot therein communicates with the nozzle for supplying the molten
metal. At this point the elevator which has theretofore been held in its raised
position, is released. In falling it strikes a lever for operating the piston of a
pump, which causes the molten metal to be injected into the mold. The
percussion causes the sudden operation of this pump piston, and molten metal
is thereby injected. This lever is then moved out of the path of the elevator,

page_text: which falls to its lowest position, where it is ready to release the matrix line
from which the type bar has just been cast.
On the floor of the assembling trough and of the distributing trough, and on
the shelf of the elevator are respectively tongues, which enter dovetail notches
in the lower ends of the matrices whereby the matrices are prevented from
falling down at any time.
Improvements in and relating to Machines for Making Type Bars.
I, CHARLES JUNGE, of Lincoln Chambers, 75, Chancery Lane, London, W.C.,
Consulting Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement; -
The invention relates to the class of machines in which independent matrices,
which are stored in magazines, are selected and released by the operation of finger
keys, are assembled in line in the order in which they are released, a type bar
is cast from said assembled matrix line, and the matrices are automatically
distributed to their respective magazines.
The invention relates particularly to the escapement by which the independent
matrices are upheld and released; to the shift mechanism by which the depres-
sion of one escapement key may be caused to operate either of several escape-
iments; to the mechanism for assembling the matrices in line, and for moving
the assembled line to the casting mechanism; to the mechanism concerned in the
casting of the type bar; to the elevator mechanism for conveying the matrices
from the casting mechanism to the distributing mechanism; to the mechanism
for distributing the matrices, and this is perhaps the most important part of the
invention; to the construction of the matrices themselves, and to the combina-
tion, with several mechanisms, of electro-magnets and electrical switches, by
the operation of which the movement of the several mechanisms is produced, or
initiated and continued until they have performed their several functions.

GENERAL CONSTRUCTION.
The two principal members of the frame are the bed 1 and an upright mem-
ber 2 which is secured to the top of the bed. On the front side of the upright
member are formed first, the magazines 3, in which the matrices are stored when
not in use; second, the assembling channels 7 which lie beneath and in open
communication with the lower ends of the magazines, and which converge and are
merged together forming finally a single channel which I call the assembling
spout 7; and third, the distributing channels 16 which lie above the open ends
of the magazine. The distributing channels converge from their lower ends
upward. being successively merged together, until at the extreme upper end
of the distributing system all of the channels have been merged together to form
one channel which is called the distributing spout 16. Or, to describe the dis-
tributing system in the reverse order, it is made up of channels which diverge
from top to bottom, and which are repeatedly sub-divided by the diverging

page_text: partitions 16b, forming two channels, until there are formed as many distributing
channels as there are magazines. At the upper end of each of the partitions
which divide said channels a gate or switch is placed, whereby either of the
branches formed by said partition may be placed into communication with the
channel of which it is a branch.
The magazines 3 are vertical channels, which are either cut into the front face
of the upright member, or formed by securing to the face of said member the
dividing partitions 3ª. These grooves are of such size that the matrices lie
therein, edge foremost, the bottom of each matrix resting on the top of that one
next below it; and the lowest matrix in each magazine is supported upon a part
of the escapement by which said matrices are released singly.
A plate, preferably made of glass, is secured over the front of the magazines
and assembling and distributing channels by means of the bolts 21, thereby
enclosing them. (See Figures 1, 2, and 24).
Supported on the bed with the right end just below the assembling spout is
the assembling trough 8,-the left end of this trough being in line with the
opening to the mold 22; and the matrices, when released from their magazines,
fall through said spout into the assembling trough.
The mold is supported in a cylindrical recess between two jaws 20 and 21 on
the bed at the end of the assembling spout; and the line of matrices assembled
in said trough is moved therefrom into the .mold.
The elevator 40 is supported on guides 40* and 40b at the left side of the
machine. It is movable by suitable mechanism from a position in line with the
discharge opening of the mold, to a position in line with the distributing trough.
The matrices are pushed out of the mold on to the elevator, after the type bar
has been cast, and, by the elevator, are carried up to the distributing trough.
The melting pot 31 is supported on the mold, and its pump is operated by the
elevator.
Supported over the distributing spout is the distributing trough 17, into
which the matrices are moved from the elevator, and along which they are moved,
until they drop into the distributing spout, by a device which is called the
propeller.
In the machine as organized a number of electro-magnets are employed to
actuate different parts of the mechanism. Normally these magnets are inert,
because the several electric circuits are broken in one or more places. Means
are provided for automatically closing the breaks in said circuits at the proper
times and holding them closed long enough for the magnets to perform their
several functions.
The electrical current for the magnets is supplied by any suitable generator R.
One wire of the generator is connected with the metallic frame work of the
machine by means of a switch ; and the other wire is connected with the
two depots 37 and 37*. These depots are insulated pieces of metal which are
placed conveniently with respect to the magnets, one on the rear side of the
upright frame member near the middle thereof, and one in the box 1" below the
base. Any magnet circuit is complete when one wire thereof is electrically con-
nected with the metal of the machine, the other with one or the other of said
depots. Two depots are employed instead of one for convenience in wiring, and
for no other reason.
The driving mechanism for the different parts of the machine are, for most
part, supported from the under side of the bed; and the bed is hinged by the
hinges 75 to a box 1°, like a cover thereto, whereby all of the parts which are
suspended from the under side of said bed are normally concealed and protected.
When said parts need adjustment or repairing, the bed may be swung back
on its hinge, thereby exposing said parts.
ASSEMBLING MECHANISM.

page_text: singly therefrom, consists of two slides 4* and 4b, and their operating mechanism.
The slide 4* lies and moves in a horizontal slot 2* in the upright member 2, which
slot enters the rear side of the magazine. In a similar slot 2, above the first,
lies and moves the other slide 4, the distance between the upper edge of said
slides being equal, substantially, to the height of a matrix. The rear ends of
said slides are connected with the arms of a pivoted lever 4°, whereby, when
said lever is rocked, the two slides are moved in opposite directions, that is to
say, when one slide is moved so that its forward end enters the magazine, the
other slide is withdrawn therefrom. When the parts are at rest, the lower slide
projects into the magazine and all of the matrices are sustained by it. The
preferred method of connecting the lever arm to the slides consists in forming
in each slide a substantially vertical slot 4*, in which the rounded end of said
lever arms lie. The said escapement and mechanism for operating it are most
clearly shown in Figures 23 and 24.
On the rear side of each lever 4° is a substantially horizontal arm 4d, which is
adapted to be moved upward by a vertically movable rod 4. This rod 4 is con-
nected with one of the key levers and is operated thereby. When a key is
depressed the corresponding rod 4 is moved upward against one of the arms 4ª,
thereby operating the corresponding lever 4°, so that the upper slide 4b is moved
forward until its end projects into the magazine beneath the next to the lowest
matrix. The lower slide 4 is drawn backward at the same time, and is with-
drawn from said magazine just after the upper slide enters it; whereupon the
lowest matrix drops out of the magazine. The upper rear edge of each matrix is
cut off or bevelled and the forward end of slide 4b is bevelled to a point so as to
facilitate the described movement of said slide beneath the next to the lowest
matrix.
When permitted to so move, the lever 4° is moved in the reverse direction to
that last described by a spring 4', and consequently the lower slide 4* is moved
into the magazine and the upper slide 4b is withdrawn, whereupon all of the
matrices move down until the lowest matrix rests upon the slide 4.
Mechanism like that just described for sustaining and releasing the matrices
is provided for each magazine; and said mechanisms may be wholly independent
of each other, and, as a matter of fact, are independent except for this, that each
rod 4 may be caused to operate either of three adjacent levers 4° by means of a
shifting device to be presently explained.
In order that the formation of the slots 2b, 2°, in the upright frame member,
for the slides 4 and 4b last described, may be comparatively easy and inexpen-
sive, said upright member 2 is formed in three parts which are bolted together
viz., the part 2 which lies above the slide 4b; the part 2b which lies below the
slide 4 and the part 2 which is secured in place between the two parts 2ª
and 2b. Before said part 2° is so secured the horizontal grooves 2d, 2°, are formed
in the upper and lower sides thereof respectively; vertical grooves 2 are formed
in the rear side thereof,-(the levers 4° lying in said grooves) and vertical
grooves 2 are formed in the front side of the part 2, which grooves form the lower
ends of the magazines 3. The grooves 2d, 20, for the slides are enclosed on their
top and bottom sides respectively by the two parts 2 2b, when the part 2° is
secured between them.
The lower ends of the vertically movable rods 4, are connected with the rear
ends of the key levers 5. The key levers are pivoted on a rod 5*, which is sup-
ported from the under side of the bed 1. Vertical rods 5b are pivoted to the for-
ward ends of the key levers, and extend up through holes in the bed plate 1, and
finger pieces 5° are secured on their upper ends. As the front ends of the key
levers are depressed by the operator, the rods are moved upward with the result
before pointed out. When the finger of the operator is removed, the weight of
the rod 4 causes each key lever to return to its first position.
The shift mechanism with which each rod 4 is moved so that it may operate
either one of three adjacent levers 4°, consists of a transversely movable hori-

page_text: zontal bar 6 through which the upper ends of the rods 4 pass loosely, which bar is
supported in horizontal grooves 2h in the sides of the upright member 2. The
bar is moved transversely to the right or left by means of two shift keys 6, 6º,
and intermediate mechanism as follows: The shift key levers are pivoted to the
under side of the bed plate 1; vertically movable rods 6° are pivoted to the rear
ends of said shift key levers respectively; the upper end of each rod is pivotally
connected to a lever 6d, which is pivoted to a plate 6°. The plate 6° is rigidly
secured to the upright frame member by screws 6" which pass through horizontal
slots 6 in the said plate 6º, whereby the position of said plate may be nicely
adjusted. Two of these plates 6° are employed, one on each side of the central
vertical plane.
Secured to or formed upon the under side of the bar 6 are two lugs, viz., 65, in
which is formed an inclined groove 6; and 6' in which is formed an oppositely
inclined groove 6. Pins 6, which are secured one to each lever 6ª, lie in the
said inclined grooves 6 and 6 respectively. When the shift key 6 on the right
side is depressed, the corresponding lever 6d is rocked, the pin 6 thereon moving
upward in the groove 6. This moves the bar 6 to the right such a distance that
the ends of all of the rods 4 are brought beneath the lever arms 4d to the right of
those under which they normally lie. When the shift key is released all of the
parts are returned to their first position by the weight of the rods 6°, or other
means. When the left shift key 6b is depressed, the bar 6 is moved to the left
an equal distance by the corresponding mechanism
Although the rods 4 will generally be long and flexible enough to permit them
to bend when the bar 6 is moved, it is thought that the connection between each
rod 4 and its key lever should be such that no bending will be necessary.
For
this reason said rods are connected to the key levers by a ball and socket joint,-
the balls 4 being formed on the lower ends of the rods.
The rods pass up
through loose holes in the ends of the key levers, and they are held in place by
screws 5d which screw into said key levers from the under side and have cup-
shaped ends. The rods 6° are similarly connected with the levers 6° as shown in
Figure 24.
The assembling trough 8 begins just beneath the spout 7* and extends. there-
from to the left to the mold. The machine as organized and shown in the
drawings is designed to produce the type bar in the same machine which
assembles the matrices, wherefrom the assembling trough leads as stated to the
mold. If, however, it should be desirable to remove the assembled matrices to
an independent casting machine, the trough may extend to any convenient
point.
As each matrix drops from the spout into the assembling trough, it must be
moved from beneath said spout to make room for the next matrix. To secure this
result, a horizontal movable plunger 9 is provided, which projects into the right
end of said trough. When at rest this plunger lies just to the right of the
spout, (see Figure 12) but immediately after each matrix falls-into the trough
the plunger makes a quick movement to the left pushing the matrix before it
until said matrix passes the pawls 8, (see Figure 20) which prevent the matrix
from moving backward. These pawls are pivoted on vertical pivots to the sides
of the trough, and project a short distance into the trough. They are forced
outward by the matrix in passing them, but are pressed inward behind the matrix
by springs 8b when the said matrix has passed.
The plunger is operated after the fall of each matrix by an electro-magnet A,
the circuit of which is completed by the matrix itself through suitable
mechanism to be presently explained.
The electro-magnet A is secured to a bracket 9 which is secured to the vertical
member of the frame. A longitudinally movable rod 45b passes centrally through
the core of the magnet and is connected with the armature. It is arranged to
thrust against a lever 9d. which is pivoted at оде end to a
bracket 9, while the other end is pivotally connected with the plunger 9.
A

page_text: spring 9 acts upon the lever to move it in the direction contrary to that in which
it is moved by the action of the magnet.
One wire a of the magnet A is connected with the depot 37. The other wire a¹
of the electro-magnet A is connected with an insulated contact block 9, which
is secured in the piece of hard rubber or other insulating material 98. (See
Figures 12 and 13). Another piece of metal 9h, which for convenience of con-
struction is secured to said insulating material, is in contact with the metal of
which the bracket 9° is composed. Secured to this metallic piece 9h is a thin
flexible metallic spring 9 which projects into the assembling trough just beneath
the spout. This spring lies normally above and out of contact with the contact
block 9', but each matrix as it drops falls onto said spring, and forces it into
contact with said block 9', thereby completing the circuit of the magnet A. The
magnet thus attracts its armature, the rod 45b thereupon moving the lever 9d,
with the result of moving the plunger 9 forward as described. As the matrix is
forced forward, by the plunger, it moves off of the spring 9*, which, being
released, flies up out of contact with the block 9, thereby breaking the magnetic
circuit of the magnet A, whereupon the plunger is drawn back by the action of
the springs 9. This action is repeated each time a matrix falls.
In order to hold the matrices in a compact line and to prevent them from
falling over, a detent 10 projects normally into the trough through a slot 8° in
its bottom, and lies just to the left of the spout 7°. (The detent and its posi-
tion relative to the other parts is shown in Figures 8, 9, 14, 15 and 16). The
detent is subject to the action of a spring 10", which tends to return it to the
above described position when it has been moved therefrom. The detent is the up-
turned end of an arm 10b which is rigidly secured to a rod 10°. This rod is
movably supported in a hole 20h in the fixed mold jaw 20 and in a hole in the
upright member 2; and it is susceptible of considerable longitudinal movement,
and of small oscillatory movement on its axis. In the construction shown a
Bingle spring 10° causes both of the described movements of the detent rod, the
construction being as follows: (see Figure 9). The rod is hollow, and contains
a long coil spring 10%, the inner end of which is fastened to the rod. The outer
end of the spring is secured to a stationary hook 14 on the switch box. When
the detent is moved to the left the spring is forcibly expanded.
When the
detent rod is turned as the detent is moved out of the trough, the spring is
twisted. When permitted so to act, the spring draws the detent rod backward,
i.e., to the right and at the same time turns it upon its axis, whereby the detent
is automatically drawn to its original position, as above described.
In the end of the detent is a spring pawl 10d, which when the detent is pushed
down out of the trough 8, automatically flies beneath the front edge of the slot 8°
in the bottom of said trough,-(see Figure 15) thereby holding the detent down
until the said pawl is pushed out of engagement with said trough. On the
under side of the trough in front of the slot therein, is a rib 8° which engages
with the front edge of the pawl 101. Near the spout this rib is inclined toward
the edge of the slot; wherefore, as the detent is drawn toward the right, this
rib pushes back the pawl 10d until it is freed from its engagement with the
bottom of the trough, whereupon the pawl under the influence of the spring 10*
springs up into the trough.
A claw 11 is secured to a rod 11°. (See Figures 8, 9, 12, 14, 15 and 16).
The rod is mounted in bearings in which it is both longitudinally and axially
movable. The bearing of the rod 11* is a sleeve 3", which is a part of the
bracket 9*. A coil spring 11b surrounds the rod 11* in said sleeve. One end of
the spring is connected with the sleeve, the other end with the rod, wherefore,
when the rod is moved longitudinally the spring is compressed, and when the
rod is moved axially the spring is twisted. When the parts last described are
in their normal position as shown in Figures 8, 12 and 15, the claw is out of
the trough and in the plane of the assembling spout 7* as shown in Figure 8. .

page_text: The end of the claw is bifurcated, and when the claw rod is moved axially to
bring the claw behind the matrices in the trough, one end. of the claw enters
the trough through the slot 8d in its front side, while the other end passes over
the top of said trough. Pivoted to the claw is a spring pawl 11° having a hook
on its end which is adapted to automatically engage with the rear side of the
trough, and thereby hold the claw in the trough, as shown in Figure 14. While
the claw is being moved to this position, the pawl 11° slides against the bottom
of the trough.
The purpose of this claw is to move the assembled matrix line to the left to a
position to be engaged by the push, to be presently explained When the
matrices to form a line have been assembled in the trough, they lie between the
detent 10 and the pawls 8°. The operator grasps the claw by its handle 11 and
turns it up into the trough, the pawl 11° engaging with the rear side of the
trough as described. (See Figure 14). He then moves the claw to the left,
pushing the matrix line and the detent before it, until said claw passes a drop
pawl 8, which is pivoted to the trough 8, which pawl falls behind the lower arm
of the claw and prevents the backward movement of said claw. The detent 10
and the claw 11, with the line of matrices between them, are now in positions
shown in Figure 10.
On the rear side of the trough is placed a releasing device, (see Figures 16
and 19) which is adapted to release the hold of the pawl 11° on the trough,
whereby the spring 11 automatically withdraws the claw from the trough and
returns it to its original position. This releasing device is a lever 11 pivoted
to the rear side of the trough in a position where it is adapted to engage with
the end of the said pawl, and one end of this lever projects above the top of
the trough in a position to be struck by the push 12. The lever is held in the
described position by a spring 11°. When the lever is moved downward by the
push arm, it strikes the pawl 11° and releases it, whereupon the claw, under
the influence of the spring, returns to its first position.
When the parts are in the position shown in Figure 16 the matrix line is
justified.
When the line of matrices has been justified it is moved along the assembling
trough into the mold which is placed at the end of said trough, by means of a
device which is called the push 12. The push lies normally outside the
assembling trough, but it may be moved into the trough and then pushed along
therein for the purpose specified. This push. 12, as shown in the drawing, is a
radial arm which is secured to the push rod 12; and it has a cross bar 12b on
its end which enters the trough 8 behind the matrices. The push rod is loosely
mounted in bearings in the vertical member and in a hole 20 in the fixed mold
clamping jaw 20, whereby said rod is susceptible of longitudinal movement and
of so much movement on its axis as will permit the push to be moved from its
normal position (as shown in Figures 8, 14 and 16) into the trough, (as shown
in Figure 15).
Surrounding the push rod 12ª is a loose sleeve 12d having an annular flange 12°
which lies in a recess between the bracket 9" and the upright member 2, whereby
longitudinal movement of the sleeve is prevented. (See Figures 9 and 22).
There is a tongue and groove connection between the said sleeve and push rod,
whereby both turn upon their axis in unison. An arm 12 is secured to said
sleeve, and the purpose of said arm is to engage with an arm 10° on the detent
rod 10, and thereby turn said detent rod and withdraw the detent from the
trough.
A rack 12 is formed on the push rod, and a pinion 13ª engages with said
rack. The pinion is loosely mounted on a vertical shaft 13, which is itself
mounted in suitable bearings in the bed and in the upright member 2; and the
shaft is constantly driven by mechanism to be hereinafter described. The pinion
rests on a collar 13b which is secured to said shaft. A clutching device is pro-

page_text: vided, whereby the said pinion is automatically connected with said shaft at the
proper time by the action of an electro-magnet B.
There are also in the machine other clutching devices, substantially like that
to be described. The same reference letters are employed to designate similar.
parts in all of them, wherefore it is believed that the description of this device
will serve as a description for them all. (See Figure 22.)
The shaft 13 is hollow. A sleeve T is loosely mounted on said shaft and it
has fastened to it a pint which passes through a longitudinal slot t1 in the shaft
into the cavity therein. A longitudinally movable rod is placed in said cavity
between a coil spring and said pin t, which spring exerts its force to move said
rod against said pin and thereby hold the sleeve T normally out of contact with
the pinion 13. The proximate faces of said pinion and sleeve T have shoulders
which are adapted to interlock when brought into contact, whereby the pinion
will be driven. On the other side of the pin t, but in contact therewith, is
another rod which is in line with the rod 45 of the electro-magnet B. The
rod may be a part of the rod 45b, as with the particular clutch now
being described; or, it may be separate from but in line with said rod, as in
the elevator clutch. (See Figure 27). A magnet for operating each of the
clutches is fixed to the frame of the machine in a position where, when its arma-
ture is attracted, the rod is forcibly moved by the rod 45b against the pin t,
whereby the sleeve T is moved into engagement with the independently revoluble
part, as in the present case the pinion 13, thus connecting the pinion and shaft.
When the magnet becomes inert, the spring acts to move the sleeve away from
said pinion.
The push rod 12 is hollow and it contains a long coil spring 12" which is con-
nected at its inner end to the rod and at its outer end with a fixed hook 14*.
(See Figure 9). This spring is expanded when the push rod is moved to the
left; and when the push rod is released, after completing its movement, this
spring draws it back to its normal position. In the end of the push is a slot in
which the pawl 12' is pivoted; and a spring pressed pin 12, which lies in a
socket in the push, bears against said pawl with sufficient force to cause it to
remain in whatever position it may be moved to. (See Figure 9). This pawl
may lie wholly in said slot, and does so lie when the push enters the mold to
push out the slug and matrix line. When the push is returned to its normal
position by its spring, an angle arm 12 which is secured to the right end of the
pawl, strikes a pin 12" which projects to the left from the upright frame member,
thereby moving the pawl on its pivot and causing it to project out from said
slot. The pawl is intended to strike the right mold door and release it from its
engagement with the assembling trough. When the door closes, a shoulder 32d
on said door engages with said pawl and pushes it back into the slot in the push.
To the right of the assembling spout is a switch box 14 which is supported
on the bed. Most of the movable parts which are supported by this switch box
are secured to the rear side of its front plate 14, and they are most clearly shown
in Figure 10, which is a rear view of the switch box with the rear plate removed.
A switch 14 is pivoted to the plate 14b near the right end thereof. The left
end of said switch hangs normally a little below a horizontal rib 14d, which is
formed on said plate 14b, but it is free to swing on its pivot within certain limits
which are determined by the slot 14' in the plate 14 and the pin 14° (shown in
dotted lines in Figure 10) which is secured to the switch and plays in said slot.
The full lines in Figure 10 show this switch in its normal position, while the
dotted lines show the same when at the other limit of its movement. The left
end of the switch is pointed, the lower edge thereof being straight; and the lower
edge coincides with the lower edge of the rib 14d when the switch is in its raised
position. The purpose of the switch is to turn the push rod on its axis to lift
the push out of the assembling trough when the rod is being drawn to the right
by its spring. This result is secured by means of an arm 12h which is fastened
to the push rod. When the push rod is turned from its normal position to bring
trough, this arm 12h is at the right of the switch 14* and does
the push into the

page_text: not therefore strike it. When the push rod is moved to the left this arm passes
under the switch 14, which is thereby lifted to the position shown in the dotted
lines in Figure 10. After the arm has passed it, the switch falls by gravity to
the position shown by the full lines in said figure; and during the rest of its
movement to the left, the arm 12h engages beneath the lower edge of the rib 14d.
When the push rod is moving to the right, this arm 12h rides up the inclined
top edge of said switch, thereby turning the push rod on its axis.
A lever 14 is pivoted to the rear side of the plate 14b near the upper left hand
corner thereof, and it extends below said rib 14d terminating in a hook-like forma-
tion 14. An arm 14 is rigidly connected with said lever 14 and extends to a
point where it may engage with one end of the spring 14" and draw it out of
contact with the wire b¹ c¹.
An arm 14k is pivotally connected with the lever 14 near the middle thereof,
and said arm extends therefrom to the right, its end projecting below the lower
edge of the switch box. This end has a hook 14' opening to the left, and the back
or right side of said hook is bevelled so that the arm 12h in moving toward the
left may lift the arm 14. The arm 14* rests upon the rib 14d, above a loosely
pivoted pawl 14, which may be easily pushed up out of the way by the arm 12h
in moving to the left. When the arm 12h is moving toward the right it strikes
the pawl 14, said pawl swings against the arm 14k covering the hook in its end,
and both are lifted out of the way by the arm 12h in passing.
It is necessary that the lever 14' shall remain in whatever position it may be
moved to, and to secure this result a little pin 14" is inserted into its end and
pressed by a small spring 14' against the back plate 14t of the switch box, thereby
acting as a friction brake to hold said lever against accidental movement.
The spring 14P is an electrical switch, which is connected with the wire bc;
and when the spring touches the wire bel, one break in the circuit of two electro-
magnets B and C is closed. The lever 14' and the parts secured thereto constitute
the preferred switch operating mechanism.
A cylindrical mold 22 lies and is movable in a horizontal cylindrical socket
between the fixed clamping jaw 20 and the pivoted clamping jaw 21. The jaw 20
is secured to the bed by screw bolts which enter the threaded holes 20k (see
Figures 27 and 35); and the jaw 21 is provided with ears 21" which are pivoted
by means of pivot 21b to ears 20 on the jaw 20. The mold socket between the
two jaws is not a complete cylinder, being opened at the top side. This opening
is closed by the nozzle of the melting pot 31 which rests upon the mold. In the
bottom of the melting pot nozzle is an opening 31" through which molten metal
may be injected into the type slot 22.
The mold 22 is a cylindrical block, through which is formed a longitudinal
opening or recess 22b, extending from end to end. This recess contains the
movable matrix. clamp 23. And when the mold clamp is in place there is, between
it and the mold, a recess (in line with the assembling trough) adapted to receive
the assembled matrix line. In the mold is formed a radial slot 22 which passes
from without inward to said recess and extends from one end of the mold to the
other.
On the outer periphery of the mold, midway between its ends, are formed the
gear teeth 22°, by means of which a moving rack 24 may oscillate said mold.
A transverse slot 22d divides said teeth, and extends into the recess 22b.
The mold clamp is provided on its rear side with a shelf 23° onto which the
matrices slide. On the edge of this shelf is a flange 23d which extends in front
of the lower edge of the matrices. A lid 23* is pivoted to the top front edge of
the clamp 23, and extends therefrom rearward over the shelf 23°. On its rear
edge is a depending flange 23b. When the matrices are resting on the shelf 23°,
the lid rests on their upper ends, and the flanges 23b, 23d, extend over their edges.
On the rear face of the clamp is a rib 23, which enters the notches 15° in the matrices,
and thereby prevent the matrices from falling over as they enter the mold. The
face of the mold which is opposed to the matrices when they are in the mold is

page_text: a plane surface against which the matrices are pressed by the clamp; and the
type slot enters through said face over the impression line on the matrices.
Spring pressed pins 23, seated in sockets in the matrix clamp and edge of the
lid, press against the side of the mold in which said slot is formed, and thereby
exert their force to move the clamp 23 forward away from that side of the mold.
A coil spring 23h which lies between the lid and clamp,-being seated in sockets
therein, exerts its force to move the lid and clamp apart. Thus, when these pins
and spring act as described, the clamp 23 is moved in two directions so as to
release the matrices from engagement with the type bar and permit them to be
removed from the mold. This movement of the mold clamp is slight, but it is
sufficient for the described purpose.
A roller 23 is pivoted to the mold clamp and extends into the transverse slot 22d
in the mold which divides the teeth 22. Pressure on this roller tends to move
the mold clamp in opposition to the springs 23 and 23, thereby clamping the
matrices in the mold.
An adjustable bar 20° extends through the fixed clamp 20 and its end projects
into the slot 23 in the mold, where it may engage with the roller 23*. The end
of this bar is cam-shaped, whereby, as the mold is turned, an increasing pressure
is applied to the roller 23 to move the mold clamp.
In order that this bar may be adjusted, so as to move the mold clamp just the
right amount, a T slot is formed in its rear end, and the T head 20 of a bolt 20°
which screws into and out of the clamp 20, lies in said slot.
A roller 21 is mounted in the front end of the pivoted mold jaw, and it rests
upon the top of the slide 24, riding in a groove 24. This groove ends near the
front of the slide, the bottom of said groove inclining up to the level of the top
face of the slide. When the slide is near its rear position, this bevelled surface
at the end of the groove moves under the roller, thereby lifting it and moving
the, jaw so as to clamp the mold between it and the fixed mold jaw.
The rack 24 is seated in a depression in the top edge of the movable slide 24.
This slide is mounted in a groove; in the bed plate, being held in place by the
ribs 24, (see Figure 34) below the casting box. The slide is provided with a
fin 24b, which projects downward through a slot in the bed. In one side of the
fin is a substantially vertical groove 24° into which a crank pin 25d projects.
Wherefore, when the crank shaft 25 to which said pin is connected revolves once,
the slide moves backward and then forward, making one complete movement.
The slide 24 in the first and last parts of its movement performs certain functions
connected with the opening and closing of the mold doors, which will be presently
explained. Wherefore, it is desirable that the said slide, may, in the first and last
parts of its movement, be able to move a short distance independent of the rack 24*.
To secure this result the rack is made shorter than the distance between the
shoulders 24d, 24, on the slide between which it lies.
In the under side of the fixed mold jaw is formed a groove 20b which is oblique
with respect to the path travelled by the slide 24. In this groove lies a sliding
bar 24, having on its front end a finger 24, which may lie between the rear end
of the rack and the shoulder 24°, and does so. lie during a greater part of the
movement of said slide. When the slide is moving toward the front end of its
path, the shoulder 24 engages with the finger 24 which is thereby pushed
forward, and, since it engages with the rack 24, said rack is likewise moved. In
moving forward, said bar 24' is likewise moved sidewise because of the obliquity
of the groove 20b in which the bar 24 lies, until it reaches a position where it
permits the slide to pass it, said slide being cut away at 24 to sooner permit
said passing. When this point in the movement of the finger is reached, it stops,
the rack stops, and consequently the mold stops, while the slide proceeds alone
until it reaches the forward end of its path, where it is stopped in the manner to
When it begins
be described, having reached the end of its complete movement.
its next, movement, by moving backward, it moves alone until the shoulder 24d
strikes the rack. The rack is then pushed backward, and it pushing upon the

page_text: finger 24 moves the bar 24' back. In its backward movement in the oblique
groove, said finger enters between the rear end of the rack and the shoulder 24°.
From the foregoing description it will be seen that at the beginning of its back-
ward movement and at the end of its forward movement (which are respectively
the beginning and ending of its separate excursions) the slide moves while the
rack and consequently the mold remains stationary. The rear end of the bar 24*
projects rearward beyond the fixed mold jaw, and it is provided with a shoulder 24h,
which by engaging with said mold jaw, limits the forward motion of said bar.
In the ends of the molds are grooves 22°, which, when the mold is in position
to receive and discharge the matrices, are in line with similar grooves 21° in the
ends of the movable mold jaw 21. These grooves are adapted to receive the
sliding mold doors 32. The length of these doors is equal to the diameter of
the mold, and when they are closed and lie wholly in said grooves 22°, the doors
cover and close the ends of the type slot, and the ends of the character line on
the matrices; while at the same time they offer no impediment to the oscillation of
the mold.
On each of the doors is a pin 32* which is adapted to be engaged by a hook 33*
on one of the door opening levers 33. The right door is somewhat loosely fitted
in the grooves 22° and 21°, and is therefore susceptible of side motion therein.
When the door is opened a spring 32b which lies in a socket in the mold 22, (see
Figure 32) pushes the door to the right when it is opened, so that the rear end
engages with the assembling trough, and thereby the door is held open, until such
engagement is discontinued by the pawl 12 in the end of the push.
The door opening levers 33 are pivoted to ears 1b which depend from the under
side of the bed plate, and said levers project upward through slots in the bed.
Between the two levers a block 35 is pivoted in the same axial line. This block
is in front of a shoulder 24' on the fin of the slide 24; and when the said slide is
moved forward, the said shoulder strikes the block and swings it forward; while
a spring or springs 35* which lie in a socket in an ear 1b, thrusts against said
block and exerts its force to move it backward:
Pivoted to the sides of said block near its upper end are the pawls 35b (see
Figures 33, 34 and 42). These pawls have slots in them through which the door
opening levers loosely pass. These pawls are adapted to fall by gravity into
engagement with shoulders 33b on the door opening levers. Rigid with each pawl
is an angle arm 35° which is adapted to engage with the fixed shoulder 35d
when the block 35 is moved forward, thereby lifting said pawl out of engagement
with shoulders 33b.
Pivoted to the left door opening lever is an arm 33d, which, when the said lever
is drawn forward to open the door, is pushed upward by the spring 33 and engages
with the elevator. The backward movement of said lever, and, consequently the
closing of said left door, is thereby prevented until the elevator ascends.
A lever 36 is pivoted to the right side of the fixed mold jaw 20. The front end
of said lever is forked, one arm lying above the other. In the end of each arm 36ª
is a friction roller 36b, which, when the mold is in position to receive and dis-
charge the matrices, bear against the end of the inold; but when the mold
has been turned to the position to receive the molten metal into its type slot, said
friction rollers bear against the right door 32 forcing it against the matrix line,
which line is thereby compressed. A strong spring 36° presses the forked end of
the lever against the mold and mold door.
Underneath the bed are several shafts all of which are mounted in posts which
project downward from the under side of the bed. The shaft 27 is the driving
shaft, and it may carry an electric motor 27b. A connecting shaft 28 is connected
with shaft 27 by gears 27, 28. Near the middle of this shaft 28 is a bevel gear 28,
which meshes with a bevel gear 13° on the lower end of the vertical shaft 13.
At the left end of shaft 28 is a bevel gear 28° which meshes with the bevel gear 29°
on the elevator shaft 29. A gear 29 on the elevator shaft meshes with a gear 30*

page_text: which is loosely mounted on the mold shaft 30. On the shaft 30 is a worm 30b,
which engages with and drives the worm wheel 25" on the crank shaft 25.
It will be seen that the shafts 28, 29 and 13 are driven constantly by the driving
shaft 27. The shaft 30 is revolved only when the pinion 30° is connected with
said shaft 30. This connection is made by means of a clutch which is similar
in construction and mode of operation to the clutch on shaft 13. That is to say,
a sleeve T is moved on the shaft 30 against and away from the pinion 30* by an
electro-magnet C and a spring pressed pin 3 respectively. The sleeve T and
pinion 30 have interlocking faces, whereby when they are in contact, both revolve
together. In the details of construction, this clutching mechanism is exactly that
heretofore described for connecting the shaft 13 and pinion 13, and the parts
aro similarly lettered, wherefore the former description will apply to this clutch-
ing mechanism.
A sprocket wheel 29b is loosely mounted on the elevator shaft. This clutching
mechanism is provided for connecting said sprocket wheel and shaft. This clutch-
ing mechanism, which is substantially like the other clutching mechanism
described, is actuated by the electro-magnet D.
On the end of the crank shaft 25 is an arm 25b, which carries the crank pin 25°.
This crank pin enters the groove 24° in the fin of the slide 24.
The elevator 40 is guided by two vertical guide rods 40°, 40b, which are secured
at their lower ends to the bed, and at their upper ends to a bracket 2 on the
upright frame member. The elevator is provided on its rear side with a trough 40°,
which, when the elevator is at its lowest position, is in line with the left opening
to the mold, whereby the matrix line may be pushed out of the mold into the
elevator trough. At the outside (left) cnd of the trough are the shoulders 40d.
(shown in Figure 32) which prevent the matrices from being pushed out of said
end. Projecting into the trough from the front side thereof is the rib 40°, which,
when the matrices are pushed into the trough, enter notches 15" in the matrices
and thus prevent the matrices from falling over.
A sprocket chain 40 passes under the sprocket wheel 29b, and over a sprocket
wheel 40, which is mounted on the upper end of the upright frame member; and
said chain lies and operates in the vertical grooves 40 in the elevator. The
elevator is fastened to the sprocket chain, whereby as the chain is moved by the
revolutions of the sprocket wheel 29 the elevator is raised until its trough is in
lino with and close to the distributing trough 17.
The distributing trough 17 is secured to, and extends horizontally across the
upper end of the frame. On its front edge is an inwardly directed rib 17d, (see
Figures 56) which enters the notches 15° in the matrices and prevents them from
falling over. In the bottom of the distributing trough is an opening 17° directly
over the distributing spout, through which the matrices drop, one by one into
said spout.
Extending horizontally across the machine above the distributing trough are
two guide rods 18, on which the propeller 18 is mounted so as to be movable across
the machine. The propeller is connected with the lower leg of the sprocket
chain 18b, which extends around the two sprocket wheels 18°, 18ª, which are
pivoted to the frame. The propeller arm 18° is adapted to enter the elevator
trough and the distributing trough, and to push the matrices from the former
into and along the latter.
The propeller is operated by a rack slide 19 which is movable vertically in
suitable guides 19 on the face of the upright frame member. On the edge of
this rack slide is a rack which engages with a pinion 19b which is rigidly connected
with the left sprocket 18° (see Figures 52 and 54). When the rack slide is
raised it revolves said pinion and sprocket with the result of drawing the propeller
to the left until it reaches the position shown in Figure 5; and when the rack
is released it falls by gravity, and revolves the sprocket in the contrary direction,
thereby causing the propeller to move to the right, pushing the matrices out of
the elevator and into and along the distributing trough.

page_text: Pivoted to the front face of the rack slide is a trip lever 19° which projects into
the path of a lug 40k on the elevator, into which position it is drawn by the
spring 19 (see Figure 7). A trigger piece 19° is pivoted to said slide rack. One
arm 19 of this trigger piece engages beneath a shoulder 19k on the lever 19° and
thus prevents the turning of said lever on its pivot when the elevator strikes it.
A second arm 198 of the trigger piece is adapted to be struck by a finger 19h
(see Figure 5) which is fixed to the upright member, when the slide rack has
reached the limit of its upward movement, thereby turning said trigger piece
and releasing the lever 19°. This lever then turns on its pivot out of engagement
with the elevator, and the slide rack falls by gravity. A spring 19" exerts its
force to move the trigger piece automatically into engagement with the shoulder 19
on the trip lever, as shown in Figure 7.
Upon the upper end of the slide rack is pivoted an arm 19", which is adapted
to strike the end of the piston rods of the dash pot S, when the slide rack has
nearly reached its lowest point. This arm 19" is prevented from swinging upward
for the time being by a pivoted latch 19" which falls by gravity behind said arm.
There is a post 19 fixed to the upright member against which the latch engages,
and as the dash pot piston settles down gradually, the said post lifts the latch 19",
permitting the arm 19" to swing up and pass the dash pot piston rod. When
the slide rack is raised, the arm 19" falls by gravity to the horizontal position, and
the latch also falls by gravity behind it.
41 represents a shift rod which extends through the base 1 up to the bracket 2"
on the upper end of the upright frame member; and it is mounted in bearings
in said bed and bracket which permit it to oscillate on its axis. This shift rod
lies in front of the right side of the elevator, as shown in Figures 1, 2, 36 and 58.
Secured rigidly to this shift rod are four arms as follows; (1) the arm 41" which
is near the upper end of said rod, and carries a pawl 41b; (see Figures 1, 2 and 58)
(2) the arm 41 having a pin 41d which enters a slot 31 in the percussion lever 31°
which operates the pump piston 31; (see Figures 1, 2 and 47) (3) the arm 41°
which lies below the bed in a position to be struck and moved by the mould slide 24
just before said slide reaches its most rearward position. This arm is subject to
continual pressure from the spring 41 to move the shift rod in the direction con-
trary to that in which it is moved by the slide, (see Figures 37, 67); (4) the arm 41',
the end of which engages with and operates the electrical switch lever 54° and
thereby makes a break in the electrical circuit of the elevator magnet. (See
Figures 37, 66 and 67).
The melting pot 31 may be of any suitable shape. On its lower side is a
nozzle 31b, containing a chamber 31° from which the molten metal is discharged
through the slot 31". The chamber 31° is separated from the main chamber of the
pot by a horizontal partition 31d, through which are one or two or more holes 31°,
which are adapted to be closed by the steel balls 31' which float in the metal in
the said nozzle chamber 31°.
In the melting pot is a pump cylinder 31s which communicates at its lower end
with the nozzle chamber 31°. The pump piston 31 extends up and out through
the top of the melting pot. A connecting rod 31 is pivoted at its ends to the
upper end of said piston; and to a lever 31 which is pivoted to the upright frame
member at a point where its free end will be engaged by a lug 40 on the side of
the elevator.
Two or more draft tubes 31k open at both ends extend up through the melting
pot, whereby they are surrounded by the molten metal therein. A gas burner 31
is supported at the foot of each draft tube, whereby the heat and products of com-
bustion of said burner passes upward through said draft tubes.
In the main pipe 31" which supplies the gas burners is a valve 31%, which valve
is operated by the electro-magnet P. A link 31 connects the armature of the
magnet P with a crank arm 31 at the valve stem. The circuit of this magnet
is completed when the lever 31° touches the end of the wire p. This lever is
moved to make this connection by a thermostat connected with the melting pot.

page_text: The form of thermostat employed consists of a tube 31 which extends up
through the molten metal. The tube contains mercury, and on the surface of the
mercury is a float 31 upon which the lever 31" rests. One end of said lever is
fulcrumed to said tube. A percussion lever 31 is pivoted by a horizontal pivot
to the upper end of the pump piston. One end of this lever lies beneath a
bracket 31 which is secured to the upright frame member, and serves as the
fulcrum of said lever. In the lever is a slot 31" into which the pin 41d projects.
When the shift rod 41 is turned, it, by reason of the described connecting mechan-
ism, turns the piston upon its axis until the end of the percussion lever lies in
the path of the elevator. When the elevator falls it strikes the said lever 31° and
the blow causes the quick downward movement of the piston and the consequent
injection of molten metal into the type slot 22°.
In the bottom of the distributing trough 17, directly over the distributing
spout 16, there is an opening 17b through which the matrices fall one by one
for distribution. Just below the distributing spout are the diverging distribut-
ing channels 16. These channels increase in number from the top downward,
said increase being due to the fact that, at intervals the channels are sub-divided
by partitions 16b. These partitions lie at an angle to one another, diverging from
the top downward. At the upper end of each partition a switch 16° is pivoted to
the upright frame member, whereby by moving said switch, the channel, on either
side of the said partition, may be placed into communication with the channel
which said partition divides. The sub-division of the distributing channels by
diverging partitions from top to bottom is repeated until there are as many
channels as there are magazines; and the open upper end of each magazine is
below the end of a corresponding distributing channel.
The switches are arranged in rows, and the number of switches in the rows neces-
sarily increases from the upper end downward. Each switch is rigidly secured to a
shaft 16, (see Figure 51) which shaft passes through the upright frame member,
in which it is journaled. A crank arm 16 is rigidly secured to the rear end of
each switch shaft. All of the arms 16° which are connected with the switch shafts
in any row are pivotally connected with a bridge bar 16'.
From the foregoing description it appears that when any switch is turned, all
of the other switches in the same row must turn at the same time. One switch
shaft in each row has secured to it an operating arm 16%, and these operating arms
are severally connected by means of the links 16h with the armatures of the electro-
magnets E, F, G, H, I, J and K.
Normally all of the switches are at their left position, being moved to and held
in said position by the several armatures which are moved from their magnets
by springs 45, (see Figure 64) when the magnets become inert; but it is clear
that by turning the proper row or rows of switches any one of the magazines may
be placed into communication with the distributing spout.
In the distributing trough near the right end thereof is a sliding block 43,
which is called the gate keeper. (See Figures 55 and 57). Passing horizontally
through it from left to right are as many insulated metallic pins 43" as there are
rows of switches and magnets for operating them. In the present case there are
seven pins which are set in insulating material with their left ends in the same
vertical plane. These pins are susceptible of small longitudinal motion, and they
are forced forward, i.e., to the left, by the spring wires 43h which connect them
with the rows of magnets E to K. This provision for moving the pins is made to
insure that all of the pins shall be brought into metallic contact with
the matrices which are intended to touch them. Secured to the bottom
of the gate keeper is a gate 43 which lies beneath the left ends of
the pins 43. When the gate keeper is at the left of its path,
the said gate covers the opening 17b, and the ends of said pins lie about
over the center of said opening. The rear (right) ends of the pins are connected
severally with the wires e, f, g, h, i, j and k of the magnets E, F, G, H, I, J and K
by small spring wires 43. Two bars 17° extend across the distributing trough

page_text: .
from the front to the back side thereof, just over the right end of the opening 17b.
The purpose of these bars is to prevent the matrices from moving to the left beyond
the opening 17b.
The gate keeper is moved backward and forward by a toggle 43° which is pivoted
at one end to the gate keeper and at the other end to the trough 17. The toggle
is connected by means of the link 43d with the armature of the magnet N. When
the magnet is energized the toggle is flexed, thereby drawing the gate keeper to
the right; and when the magnet circuit is broken and the armature is retracted
by the spring 45d, the toggle is straightened, thereby moving the gate keeper to
the left. When the gate keeper moves to the right the opening in the distributing
trough is uncovered and that matrix which is above said opening falls through it
into the distributing spout.
In order to prevent any matrix except the right hand matrix from falling
through said opening, a device which is called the pinch is provided for imping-
ing against the next matrix and holding it immovable while the first matrix is
falling. This pinch is a curved arm 44 which is rigidly secured to a rock shaft 44".
This rock shaft is mounted in bearings 17" secured to the distributing trough.
The pinch enters a hole in the rear side of the distributing trough just at the left
end of the opening 17b. Secured to the rock shafts is the operating arm 44b, and
this arm is connected by two links 44° and 444, to the armatures of the two electro-
magnets L and M.
The matrices 15 are small rectangular pieces of metal, each having the character
depression 15 in its rear edge. Near the upper end of each matrix one or more
transverse holes 15° are made, said holes being placed in one or more of the seven
positions shown on the matrices in Figure 17. These positions correspond to the
positions of the seven pins 43* carried by the gate keeper 43, and the purpose
of these holes is to prevent the matrix, when it is moved against the pins, from
completing the magnetic circuits in which those pins are connected which directly
face the holes. The holes are large enough to permit the pins to enter them with-
out coming in contact with the matrix. It is apparent that there may be many
different combinations and arrangements of said holes in said matrices, and in
point of fact the machine contains as many different kinds of matrices, as there
are magazines. The matrices vary in thickness in their body parts, in which
parts the character depression is formed, in accordance with the width of said
characters. But the upper parts of all of said matrices are of the same thickness,
the right side of said matrices being cut away, substantially as shown, to produce
this result. This right side is the side which is moved against the pins 43*, and
the matrices are cut away as described to make them of equal thickness at their
upper ends, so that when any matrix is in contact with the pins, the next-matrix
will be in position to be engaged by the pinch.
Before proceeding further in the description of the different parts of the machine,
a description will be given of the electro-magnets, the electric circuits, and the
means for completing and interrupting said circuits.
The magnets may be of any suitable construction, but it has been found that the
form of magnets shown in the drawing has characteristics which especially adapt
it for use in the described machine. The construction is clearly shown in
Figures 64 and 65. The core 45" is hollow, and a rod 45b is movable freely
through it. The armature 45° is secured to one end of this rod.
A spring 454,
contained in a recess in the core, exerts its force to move the armature away from
the core.
The magnet is contained in a case 45%, which case is secured to the
machine in a suitable manner.
As previously stated, the circuits of these magnets are severally completed when
one pole thereof is electrically. connected with the metallic frame of the machine,
and the other pole is electrically connected with one or the other of the two
depots 37 and 37*. The circuits of all of the magnets are consequently inert,
because one or more breaks are made therein, either between the magnet and the
depot, or between the magnet and the machine, or both. And mechanism is pro-

page_text: vided for automatically closing these breaks and thereby energizing the several
magnets.
In Figure 26 the electric circuits are shown diagramatically; and especial
attention is directed to this figure in connection with the following description.
The magnet B is the push rod magnet; and its function is to operate the clutch-
ing device which connects the pinion 13" with the revolving shaft 13. This
magnet is secured to the rear side of the upright member in such position that its
rod 45 enters the hole in the shaft 13 and is connected with (that is to say, is
a part of) the rod t*.
The magnet C is the casting box magnet. Its function is to operate the clutch
which connects the mold shaft 30 with the revolving pinion 30°. It is secured by
a strap to the under side of the bed, and its rod 45b bears against the end rod t* of
the clutch.
One wire b¹ of the magnet B, and one wire c¹ of the magnet C, extends to a point
just below the fixed mold clamp 20, where they are secured to the insulated block 46*.
(See Figures 30 and 37). A spring 46b lies between these two wires, and it is
adapted to be moved into contact with either. This spring is connected with the
machine, whereby the electrical connection with the machines may be made for
either magnet B or C, depending upon whether the spring 46b is in contact with
one or the other of said wires b1 or c¹.
This spring 46 is moved by a piston 46, which is movable vertically in a
recess 20 in the fixed mold jaw 20, the end of said spring lying between the two
shoulders 46 and 46d on said piston. The piston socket intersects the recess 20h
in which the detent rod 10° moves. On the piston is a disk 46° under which the
pointed end of the detent rod passes, thereby lifting the piston and causing the
spring 46 to touch the wire c¹ of the casting box magnet C. When the piston
is thus lifted a spring actuated lever arm 46 moves beneath its lower end and
upholds it until said arm is pushed out of the way by the bevelled shoe 25ª on the
end of an arm 25° which is secured to the crank shaft 25. When the arm 46° is
thus pushed out from under the piston 46 said piston falls, thereby moving the
spring 46 out of contact with the wire c', into contact with the wire b¹.
The wires b and c from the magnets B and C are united to form the wire bc,
which wire goes to the switch box 14. A. wire b c which is connected with the
depot 37 also extends to the switch box, where it is connected with the insulated
spring 14. When this spring. is released by the arm 14 it springs into contact
with the wire b c, and the connection is made between both magnets B and C
and the depot. This connection being made, the circuit of the magnet B is com-
pleted when the spring 46b is in contact with wire b: and the circuit of magnet C
is completed when said spring is in contact with the wire c.
D is the elevator magnet, and its function is to operate the clutch which con-
nects the sprocket wheel 29b to the elevator shaft 29. It is secured below the base
in such position that its rod 45b engages with the end of the rod t of said clutch.
One wired of this magnet is connected with the depot 37; while the other wire d'
is set into the insulating block 53. (See Figures 37, 66 and 67). This block is
secured to the under side of. the bed below the elevator. Secured to this insulated
block is a piece of metal having two spring arms 53, 53°. The former arm lies
beneath the wire d, and if permitted to do so, springs up into contact with the
said wire. The other spring arm. 53° normally presses upward against some
portion of the machine, as the pin 53d. (See Figure 30). A piston 53° is vertically
movable in a socket 20d in the fixed jaw clamp 20, which socket intersects the
hole 20 through which the push rod 12° passes; and the said piston enters said
hole and is pushed down by said push rod. On the lower end of this piston is a
piece of insulating material 53' which lies above and in contact with said spring
arm 53°. Consequently when said piston is pushed down by the push rod, said
spring arm is pushed out of engagement with the pin 53d.
Pivoted to the under side of the bed is a lever 54 having three arms. (See
ures 37 and 66). One arm 54* passes up through the bed, and may be swung
to enter the left end of the elevator trough. Another arm 54b is made of

page_text: insulating material and it lies above and in contact with the spring arm 53h.
When the said lever is rocked so that the arm 54* enters the elevator trough, the
other arm 54b presses down upon the spring arm and withdraws it from contact
with the wire . A friction spring 54d surrounds the pivot of said lever 54, and
presses upon said lever so that it remains in whatever position which it may bo
moved to.
The third arm 54° has a bevelled surface at 54°, which surface is adapted to bo
engaged by an arm 41' which is secured to the shift rod 41,-the result of such
engagement being to rock the lever 54 and cause the arm 54" thereof to enter the
elevator trough. The shift rod 41 is moved to produce said result by the spring 41.
As before stated, another arm 41° is secured to said shaft and projects to a point
where the slide 24 will engage with it when near the front end of its path of
travel, thereby moving such shift rod in opposition to the spring 41.
The magnets E, F, G, H, I, J and K operate the several rows of switch gates 16°.
The construction, connection and mode of operation of all of these magnets is the
same. They are secured in a substantially vertical position to the rear side of
the upright frame member. One wire e, f, g, h, i, j and k respectively of each
magnet is connected with the depot 37. The other wires are branched, and one
branch e, f, g¹, h¹, i¹, j¹ and are connected severally with the several pins 43*
on the gate keeper, while the other branches e², f³, g³, h³, ³, 1, and respectively
are connected with the springs 49°, 49, 49, 49, 491, 491 and 49 (See Figure 62).
When a matrix touches any one or more of the pins 43 the connection between the
corresponding magnet or magnets and the machine is completed through the
matrix itself. The armatures of these magnets being connected respectively with
the links 16h, the rows of gates, which are severally operated by the movement
of said links, are swung. For example, if a matrix having four holes 15° is moved
into contact with the pins 43", three of said pins only will. be touched by the
matrix. The circuits of the three corresponding magnets will be completed and
the three magnets will be energized, with the result of swinging the three corre-
sponding rows of gates. Whenever any matrix is moved against the bunch of
pins, all of the magnets which are connected with whichsoever of the pins said
matrix touches, will be energized by the completion of their circuits, and the
corresponding rows of gates will be swung.
Were this connection, made by the matrix, the only one made for said magnets,
said connection would be broken as soon as the matrix dropped away from said pins
into the distributing spout, and as a result the gates might swing back to their
normal positions before the matrix had reached its proper magazine. To prevent
this action, the wires e³, f³, g³, h², ³, j², and are connected as before stated with
the insulated springs 49h. On the lower end of each magnet rod 45b is secured a
finger 45 which, when the armature is attracted, is moved into contact with that
one of the springs 49h which is beneath it, thereby connecting the said magnet
with the machine through said rod 45b.
The switch-back is a horizontal bar 50 which is pivoted at its ends to the upright
frame member below the row of magnets last described. Secured to this bar are as
many plates 50b of insulating material as there are springs 49h. The ends of said
plates lie above the ends of said springs. An arm 50° is secured to said bar and
this arm is connected by means of the link 50d with the armature of the electro-
magnet O. When the circuit of this magnet is completed, the movement of its
armature rocks the switch-back on its pivot, and the plates 50b bear down on the
springs 49, thereby withdrawing them from contact with the fingers 45'. This
breaks the circuits of all of the magnets E to K, whereupon the gates return to
their normal position.
Secured to the insulating plates 50 b is a metallic bar 50°. Springs 50° are
connected with this bar and extend therefrom rearward to points beneath the
fingers 45', so that when any one of said fingers is moved down, it strikes not only
one of the springs 49h, but one of the springs 50% as well, thereby establishing a
metallic (electrical) connection between said bar 50* and the machine.

page_text: The magnets L and M operate the pinch 44. One wire from magnet L is
connected with the depot 37. The other wire is connected with the bar 50*.
From the foregoing description it is evident that when any one of the
magnets E, F, G, H, I, J and K is energized, and its armature moves down, the
corresponding finger 45', by coming in contact with one of the springs 50%, com-
pletes the circuit of magnet L; which thereupon attracts its armature with the
result heretofore pointed out, of operating the pinch and causing it to impinge
against the matrix which is next to the front matrix.
One wire m of the magnet M is connected with the depot 37. The other wire m¹
is connected with the insulated spring 52, which is so placed that when the gate
keeper toggle 43 is bent to draw the gate keeper to the right, a shoulder 43 on
said toggle comes in contact with said spring and remains in contact with it until
said gate keeper is near to its normal position. The connection between the
magnet M and the machine is thus made through the gate keeper, whereupon
the magnet M becomes active and attracts its armature. This holds the pinch in
contact with the matrix named heretofore; and this magnet M remains active until
the gate keeper has nearly reached its normal position, which is later than the
time when the circuit of the magnet L is broken.
The magnet N operates the gate keeper. One wire n from this magnet is
connected with the depot 37. The other wire is connected with
an insulated spring 56 (see Figure 51) which is secured to the upright
frame member 2 below the magnet rod 45 of the magnet L. When the
circuit of said magnet L is completed, and the armature moves down, the magnet
rod 45 touches said spring 56, thereby completing the electrical connection of
the magnet N with the machine, and completing the circuit of the
magnet N.
The said magnet thereupon becomes active and attracts its
armature with the result of flexing the toggle 43° and moving the gate keeper to
the right. When the circuit of magnet L is broken, the rod 45 thereof moves
away from the spring 56, breaking the circuit of the magnet N. This permits the
spring 45d of magnet N to straighten the toggle 43° and move the gate keeper
to the left.
The magnet operates the switch-back. One wire o from this magnet is
connected with the depot 37. The other wire o' is extended to a point to the right
of the gate keeper where it is connected with the insulated spring 51ª.
The governor 51 is in the form of a tube. It is pivoted near its center to the
upright frame member so that it may be rocked to elevate either end. In the
tube is a metallic ball 51* which, as the end of the governor is elevated, rolls
down to the other end.. One end of said governor is slotted, and the spring 51ª
is so placed that it enters the slot therein, but does not touch the governor.
Secured to the governor is an operating arm 51b, which arm engages with and is
operated by a rod 43, which projects from the right end of the gate keeper.
When the gate keeper is moved to the right by the action of its magnet, the
governor is rocked so as to depress its slotted end. The ball 51 rolls down to
said slotted end, strikes the spring 51d, thereby completing the circuit of magnet O.
The magnet 0 oscillates the switch-back through the mechanism heretofore
described. As the switch-back moves, it, by engaging with the tops of the
springs 49 draws them away from contact with the fingers 45'. This breaks
the connection of all of the magnets E to K, whereupon the springs 45d lift the
armatures of said magnets, and this returns all of the gates to their normal
position.
The same movement of the switch-back withdraws all of the springs 50 from
contact with said finger 45', whereby the connection between the bar 50 is
broken. This breaks the circuit of the magnet L. The spring 45d in said magnet
moves the armature away from said magnet L, consequently (1) the connection
between the rod 45 of magnet L and the spring 56 is broken, and this breaks
the circuit of the magnet N. The armature of said magnet recedes from the core
and thereby the gate keeper's toggle is straightened and the gate keeper moved
to the left of its normal position. (2) When the toggle is straightened, the con-

page_text: nection between said toggle and the spring 52 is broken, thereby breaking the
circuit of the magnet M. The springs 45 in magnets L and M rock the pinch
shaft and withdraw the pinch from contact with the matrices.
As the gate keeper moves to the left the governor is rocked, whereupon the
ball rolls toward the other end thereof, and the connection between it and the
spring 51 is broken. This breaks the circuit of the magnet O and leaves the
switch-back free to return to its normal position. It is caused to return to said
position by a spring 52". This spring is enclosed in a barrel 52 which is fixed
to the upright frame member. A piston 52b is movable in this barrel above said
spring, and this piston is connected by the link 52° to the arm 50 on the
switch-back.
Secured to the left end of the box 1ª is a shelf or bracket 57, which serves for
a galley to receive the type bars as they are cast. Between this galley and the
mold is an inclined chute 57", into which the type bars fall as they are pushed from
the mold. Said type bars fall down said chute into the galley in which they stand
on one end with the printing edge out so that it may be inspected.
The front side 576 of the chute 57" lies close to the elevator trough. As the
matrix line and type bar are pushed from the mold, the former enters the elevator
trough, while the top side of the latter (on which the characters are formed) rests
upon the front 57b of the chute. The bottom of the type bar being unsupported
falls down into the chute.
The rock shaft 58 mounted in suitable bearings on the bottom of the box passes
through the end of the box 1". On the outer end of this rock shaft is an arm 58"
which is adapted to move against the last type bar which entered the galley and
push it and all of the other type bars forward so that the next type bar formed may
enter the galley from the chute. On the end of the shaft within the box an
arm 58b is secured, which arm is adapted to be struck and moved by the crank
arm 25 on the crank shaft 25. A spring 58° which is interposed between the
bottom of the box 1" and an arm 58d on the rock shaft, returns the rock shaft to its
normal position.
The operation of the machine will now be described. The matrices are released
singly from their magazzines 3 as the several escapements are operated by the key
levers 5. The shift keys 6" or 6b are depressed when it is desired to move any
escapement operating rod 4 to the right or left so that it may engage with and
operate the escapements respectively to the right and left of that which it operates
when in its normal position.
As the matrices are released they fall by gravity down the converging assembl-
ing channels 7 through the assembling spout 7 into the assembling trough 8.
They fall onto the spring 9k and the weight of each matrix forces said spring
against the contact block 9' thereby completing the circuit of the magnet A. The
plunger 9 which is operated by said magnet thereupon pushes the matrix to the
left past the pawls 8". In moving to this position the matrix is moved off of the
spring 9, which being released springs away from the block 9 and the electric
circuit is broken. This operation is automatically repeated each time à matrix
falls until a line of matrices is assembled. When no more full words or syllables
can be added to the line, small spacers are released and assembled until the line is
full. A line is known to be full when the left edges of the first or left matrix is in
line with the line 8k on the edge of the trough 8. The detent 10 projects into the
trough during the assembling of the matrix line and is moved step by step to the
left as the matrices are added. When the line is full, the claw 11 is turned up
so as to enter. the trough behind said line. The claw is then moved to the left,
pushing the matrix line and detent before it, until the drop pawl 8 falls behind
said claw, as shown in Figure 16.
The detent rod in the last part of its movement to the left passes beneath the
disk 46° on the piston 46, (see Figure 30) thereby lifting said piston and drawing
the spring 46 into contact with the wire c of the casting box magnet. When the
piston has been so lifted, the spring lever arm 46 moves beneath its lower end

page_text: and holds it up. One of the breaks in the circuit of the casting box magnet C
is now closed.
When the matrix line is in the position shown in Figure 16 the spacers which
were added to the end of the line are re-arranged, being placed by hand between
the words, if such re-arrangement is necessary and desirable.
The operator then takes hold of the push 12 and turns it down into its horizontal
position, the end of said push entering the assembling trough behind the matrix
line. In moving to this position, the push strikes and moves the lever 11 which
by its movement releases the pawl 11° from engagement with the trough 8,
whereupon the claw returns to its normal position. The arm 12' is likewise moved
by the push rod against the arm 10e on the detent rod, thereby turning said detent
rod and withdrawing the detent from the trough. The pawl 10d engages with the
bottom of the trough, and the detent is returned to its first position by the
spring 10".
"
The operator then moves the push to the left, pushing the matrix line into
the mold. At this time the left door has been closed sufficiently to cover the end
of the space into which the matrices are pushed. When the matrices are in the
mold the pawl 12 in the end of the push strikes the right door and pushes it out
of engagement with the assembling trough, whereupon said door is closed, or
partly closed by its operating lever 33. And in this movement the door pushes
the pawl arm back into the slot in the end of the push. The operator then releases
the push and the push rod is moved by its spring backward until the arm 12h on
said rod engages with the hook 14' at the switch box and draws backward upon it.
This moves the switch lever 14' and arm 14 which is fastened thereto, thereby
permitting the electric switch spring 14" to move into contact with the wire b¹c¹.
This completes the circuit of the casting box magnet, which magnet thereupon
operates the clutch which connects the shaft 30 with the pinion 30". This causes
the shaft 30 to revolve, and this movement is transmitted through the worm 30b
and worm wheel 25" to the crank shaft 25. A slow revolution of the crank shaft
follows, which revolution results in the backward and forward movement of the
slide 24. The first backward movement of the slide withdraws the shoulder 24'
from contact with the block 35, which block thereupon, under the influence of
its spring 35, swings backward. This movement of the block permits the
springs 35 to move the levers 33 and completely close the mold doors. The
springs 35 are coil springs which lie in the barrels 35 which are attached to the
block 35 and they thrust against the levers 33. At the same time the pawls 35b
are permitted to drop into engagement with the shoulders 33b on the levers 33, so
that when the block is subsequently swung forward said levers are likewise moved.
The further movement of the slide causes the shoulder 24d to engage with the
rack 24, which rack is thereupon moved backward by the slide. The movement
of the rack turns the mold in its socket between the two clamping jaws 20 and 21,
until the type slot 22 is in communication with the nozzle of the melting pot.
During this movement of the mold the elevator has remained upheld in line with
the distributing trough by means of the pawl 41b on the arm 41" which is attached
to the shift rod 41. Just the instant before the slide reaches its rear position, it
strikes the lever 41° which is attached to said shift rod, thereby turning said shift
rod and accomplishing two results, as follows: First, the pawl 41b is withdrawn
from engagement with the elevator, thereby permitting the elevator to fall by
gravity; second, the arm 41° moves the percussion lever 31 into the path of the
elevator. Upon the withdrawal of the pawl 41b from engagement with the
elevator, the elevator falls upon the lever 31, and by the percussion suddenly moves
the pump piston 31d downward and forces the molten metal into the type slot.
Just before the slide has reached its rearmost position on the inclined forward end
of the groove 24" in the top of the slide 24 moves beneath the roller 21d on the
front end of the pivoted mold jaw 21, thereby moving said mold jaw and causing
it to clamp the mold and hold it firmly for the instant during which the molten
metal is forced into the type slot. As the rack moves backward it pushes against

page_text: the finger 24 on the oblique bar 24h and moves it backward. In its forward
movement the finger enters between said rack and the shoulder 24°. When the
slide 24 begins its forward movement it pushes upon the finger 24" and it moves
the rack directly,--which rack turns the mold backward. When the mold has
reached its normal position, the finger 24 on the oblique bar 24h has moved from
between the rack and shoulder 24°, whereupon the rack stops and the slitle
proceeds alone to its normal position. During this latter movement tho
shoulder 24¹ strikes the block 35 and swings it forward. By reason of the con-
nection with the pawls 35b engaging with the door operating levers 33, said
levers are moved forward with the result of opening the doors. The right door
moves out into engagement with the assembling trough and is thereby held open
until released in the manner herein before stated. The spring arm 33d on the left
door opening lever flies up in front of the elevator, which in the meantime has
descended to its lowest position,-the further forward movement of the block
causing the arms 35° on the pawls 35b to strike the fixed shoulders 35d and thereby
lift the pawls out of engagement with the door opening levers, leaving them free
to operate independent of the movement of the block.
When the slide 24 began its forward movement it moved away from the arm 41°
on the shift rod, whereupon the spring 41 operating upon the arm 41' turned the
shift rod until the pawl 41b engaged with the elevator guide 40%. This moves
the purcussion lever 31 of the melting pot out of the path of the elevator,
which elevator thereupon falls to the lowest position, preferably striking the
piston 60 of the dash pot to relieve the jar.
On the crank shaft is an arm 25b having on its end a bevelled shoe 25°, (which
arm stands when the crank shaft is at rest in the position shown in Figure 30)
which shoe strikes the spring arm 46 and pushes it from beneath the piston 46,
which piston thereupon falls, thereby forcing the spring 46 into contact with the
wire band this completes the circuit of the push rod magnet B. The crank shaft
stops directly after the arm 46 has been pushed from beneath the piston as
described; the mold having at that time been returned to its normal position.
(See Figure 30). This magnet B operates to connect the pinion 13 with the
revolving shaft 13, and thereupon the push rod is moved to the left. The push
enters the mold pushing the matrices into the elevator trough and pushing the
type bar out of the mold past the shearing knives 56 into an inclined chute 24ª
in which chute the type bar slides to the galley 54. The shearing knives are
bolted to the left side of the fixed mold clamp, and extend forward therefrom,
one of said knives lying just over and one just below the end of the type slot 22ª.
As the type bar is pushed endwise from the slot, it passes between said knives
which trim and smooth down the sides of said type bar. Two tubes 56° are
connected with said knives, and the shavings from the type bar enter said tubes
and are by them conducted away. The pointed end of the push rod moves over
the piston 53°, thereby pushing it downward against the spring arm 53°. This
breaks temporarily the electrical connection between said spring arm and the
machine. When the matrices enter the elevator trough they strike the lever
arm 54 and move the lever 54, thereby withdrawing the insulated arm 54b of
said lever from its engagement with the spring arm 53b, which arm is permitted to
move into contact with the wire d¹.
When the push rod has reached the position in which the type bar and matrices
are wholly removed, as described, from the mold, the arm 12 on said rod strikes
the hook on the lever 14' at the switch box, thereby moving said lever and causing
the arm 14 to withdraw the spring out of contact with the wire b¹ c. This breaks
the connection of the push rod magnet B, (also magnet C) whereupon the push
rod spring 12ª draws the push rod back to its normal position. In moving to this
position the push rod withdraws itself from engagement with the piston 53º,
whereupon the spring arm 53° moves up into contact with the machine, thereby
completing the circuit of the elevator magnet. As the push rod continues its
movement to the right, the arm 12h strikes the pawl 14 pushing it so as to

page_text: cover the hook 14' and the link 14 is lifted, permitting said arm 12 to pass.
Said arm strikes the pointed end of the switch 14*, rides up the inclined end
thereof, thereby turning the push out of the assembling trough to its vertical
position, which is the position shown in Figure 8, and is the. normal position of
said push. All of the parts of the device which have to do with the assembling
of matrices and casting of the type bar have now returned to their normal position
in readiness to repeat the above described operations.
When the circuit of the elevator magnet is completed, the sprocket wheel 29b
is by the operation of a clutch connected with the elevator shaft 29; the elevator
chain 40 is thereupon moved and the elevator is raised to a point in line with
the distributing trough 17. In moving to this position, the lug 40 of the
elevator strikes the trip lever 19h on the slide rack 19 and the said slide is
carried upward by the elevator; in its upward movement it revolves the pinion 19b,
thereby revolving the sprocket wheel 18°. This causes the chain 18b to move so as
to draw the propeller 18 to the left until it reaches a position, as shown in Figure 5,
to the left of the elevator; when it reaches this position, the trigger arm 19t
strikes the fixed tripping finger 19h, thereby moving it out of engagement with
the shoulder 19k on the trip lever. The trip lever being free to move, swings on its
pivot releasing its hold on the clevator, whereupon the slide rack falls to its
original position. The jar incident to said falling is relieved by the arm 19"
striking the pistons of the dash pot S. As said piston settles down, the latch 19P
strikes the fixed post 19, whereupon said latch is lifted and the arm 19" swings
upward on its pivot permitting the further downward movement of said slide
rack.
Just before the elevator reaches its highest position the lug 40' engages beneath
the lever 31, thereby lifting it and the melting pot piston 314.
When the slide rack falls it revolves the pinion 19b and sprocket wheel 18°,
thereby causing the propeller to move to the right. In this movement it pushes
the matrices out of the elevator trough into and along the distributing trough
until the right hand matrix is brought into contact with the bunch of pins 43*
carried by the gate keeper. Whenever a matrix drops into the distributing spout,
the weight of the slide rack moves the propeller and the propeller moves the line
of matrices until the next matrix is in contact with the said pins. When the
elevator is down, the pawl 41b on the upper arm 41* of the shift rod is in a
substantially horizontal position and its end rests against one of the elevator
guide rods 40 and thus prevents the shift rod from being turned by its spring 415;
but when the elevator in ascending strikes the pawl 41b it lifts it, and when the.
bottom of the elevator passes above the arm 41, said arm flies beneath the
elevator, thereby turning the shift rod. This movement of the shift rod causes
the lower arm 41' to bear against the bevelled surface 54° on the arm 54°, thereby
moving said arm and withdrawing the spring 53b from contact with the wire di.
This breaks the current of the elevator magnet, but the pawl 41b has entered a
notch 40 in the front side of the elevator, whereby said elevator is held up until
the shift rod is moved in the contrary direction by the action of the slide 24, as
herein before described. The elevator current switch lever 54, as before stated, is
subject to the action of the tension spring 54d by means of which said current
switch lever maintains any position into which it may be moved. It will be seen
that the elevator is held up by the described mechanism until a second line of
matrices is introduced into the mold and the mold has been turned by the backward
movement of the slide 24 to bring the type slot into communication with the
melting pot. When the mold is in this position relatively to the melting pot,
the slide 24 is at the rear end of its path at which time it strikes the arm 41°.
thereby turning the switch rod in the direction opposed to the spring 415. This
movement of the shift rod releases the elevator, which thereupon falls, striking
the percussion lever of the melting pot and injecting molten metal into the type
slot in the mold. When the slide has moved forward it permits the spring 41°
to turn the shift rod so as to withdraw the percussion lever from the path of the

page_text: Beneath the
elevator, whereupon the elevator falls to the bottom of its path.
elevator is a dash pot of ordinary construction, the piston 60 of which is shown
in Figure 66. This relieves the machine of considerable jar which would other-
wise be incident to the fall of said elevator.
As each matrix is moved by the propeller against the bunch of pins in the gate
keeper, the several magnets which operate the switches, the pinch, the gate keeper
and switch-back, are automatically magnetized by the completion of their currents,
and demagnetized by the breaking thereof, in the manner and order heretofore
described. When the gate keeper moves to the right the right hand matrix can
move no further to the right than the stop bars 17°, which extend across said
trough. The gate covering the distributing spout is withdrawn and said matrix
drops into the spout following the channel made for it by the action of the
magnets, and finally lands in its own magazine and the gate keeper returns to its
normal position and the pinch releases its hold upon the next matrix in the line
and the propeller moves the said matrix against the bunch of pins, and this action
is repeated until the entire line is distributed.

ing channels which converge from the lower ends upward and are finally merged
together into one channel, assembling channels which converge from their upper
ends downward and are finally merged into one channel, and magazine channels
which are intermediate of said assembling channels and distributing channels
and are in communication with both, with switches pivoted in the distributing
channels and escapements in the lower ends of the magazines, substantially as
and for the purpose specified.
81. A series of matrices each having one or more transverse holes, which holes
are differently arranged on the different matrices, substantially as and for the
purpose specified.
82. In a machine for forming type bars, a series of magazines containing
matrices of various thicknesses, except that the corresponding parts of said matrices
are cut away on the right side thereof to make these parts of uniform thickness,
said matrices having, through the uniformly thick parts, one or more transverse
holes which are differently arranged on the different matrices, substantially as and
for the purpose specified.
83. The combination of the distributing trough, a propeller adapted to push
the matrix line along said trough, mechanism for operating said propeller, a slide
rack adapted to operate said mechanism, the elevator, and a trip lever for con-
necting said elevator and slide rack, substantially as and for the purpose specified.
