I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of The Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street, Manchester
both in the County of Lancaster 118, New Street, Birmingham in the County
of Warwick and 31 High Holborn in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The invention relates to the class of machines of which the primary purpose is to
impress, one by one, into suitable material, the letters and characters which it is
desired to have appear in a line of printed matter, thereby forming a mold from
which a linotype may be cast.
The improvements have to do principally with the construction of the dies, and
the means for supporting them in the machine in such manner that they are
severally capable of being brought to the impression point; to the mechanism for
moving the dies severally to and from the impression point; to the mechanism for
imparting to the impression receiving material a differential feed movement; to the
combination of parts whereby the machine may be used either as a matrix making
machine or as a typewriter; to the key mechanisin, including (1) the connections
between the keys and their corresponding dies, (2) the means for insuring the
complete action of a key whenever its movement is initiated, and the consequent
correct action of all the parts which the depression of a key is intended to set in
notion, and (3) the mechanism for returning the parts to their normal position; to
the novel application of power to the several parts of the machine; to the details
of construction of the different parts of the machine and to the combinations of
parts which co-operate in preducing the complete result aimed at and the different
parts of said result. All of which will be presently explained and pointed out
definitely in the claims.

All of the parts of the machine are supported by a rigid frame, which, in the
form shown, is constructed as follows, to wit: with two side pieces 1 and 2 which
are connected by a front brace 3 and a top plate 4. At the transverse centre and
near the rear edge of the top plate is portion 5 of the frame which extends both
above and below the plane of the top plate and also rearward therefrom.
This
portion of the frame supports numerous parts of the operating mechanism, as will
be presently explained. A back plate 6 is bolted to the sides 1 and 2 and to the
portion 5, and its principal function is to support the carriage. Near the front
edge of the top plate are the three posts 7, 8 and 9; and behind them and on
opposite sides of the central line of the machine are the two posts 10 and 11.
Preferably all of the parts of the frame above named, except plate 6, are cast in
one piece.
At the front of the machine are the keys 63 which are attached to the key
levers B, which are of equal length. At the rear of the machine is the transversely
movable carriage U which supports the impression receiving material. Just in
front of the carriage are the dies A which are arranged in a transverse row, with
their characters facing rearward; and they are adapted to be carried separately to
the transverse center or impression point of the machine. The mechanism for
operating the shuttles by which the dies are moved is for most part mounted on the
top plate; and said mechanism is operated by a spring motor also mounted on the
top plate. The feed mechanism is placed below the plate 6 which supports
the carriage, in position to be actuated by the projecting lugs on the die cases.
Having now described generally the relative positions of the several parts mainly
concerned in the different movements of the machine, the construction of these
parts in detail will now be described.
The dies A are cylindrical pieces of steel, each of which is secured at or near its
middle to the top of a shank which lies substantially at right angles to the die.
It is preferable to form the shank of two parallel spring wires a a². The shank
passes through a normally vertical aperture in the case a, and it is adapted to
slide treely to and fro in said case, but cannot turn therein. Each case is pivoted
to the rear vertical edge of a slide a³, by means of a cylindrical pin a which is
secured to the lower edge of the case and enters a hole in the slide. A coiled
spring a surrounds the pin and lies in a recess as in the slide. One end of the
spring is attached to the slide and one end to the pin a', and it exerts torsional
force to turn the pin in its bearings and thereby bring and hold the case against a
shoulder a' on the slide. On the shank wires are the shoulders a³ which rest on
the top edge of the case and thus uphold the dies at the proper elevation. In the
die holding bar F are numerous horizontal grooves in which slides a³ are
movably supported. Two of these die holding bars F are employed, and each
receives and supports half of the slides a³ which are employed in the machine.
These bars are supported on the cross: barf which is secured to the frame. The
ends of the bars F are guided between the vertical shoulders f¹ƒ on the sides 1

page_text: ชมน од The part of the frame. Le Dars may be removed by means or
the handles f³, and other bars substituted which carry dies having different styles
of type.
The shanks of the dies preserve the connection of said dies with their respective
cases while said dies are being moved to the impression point at the centre of the
machine. The shanks are of different lengths; the nearer to the centre is the
normal position of any die, the shorter is its shank. It will also be noticed by
reference to Figures 9, 10, 11 and 12 that the characters on the several dies are
inclined when the dies are in the line of dies and when, consequently, the die
shanks are vertical; and that the farther the normal position of any die is from
the centre, the greater is said inclination. The position of the characters on the
several dies is such that when any die is at the impression point the character
thereon is upright, as shown in Figure 24.
A transverse cylindrical rod b is attached at its ends to the brackets 12 which
are secured to the sides 1 and 2 of the frame; and this bar passes through and
serves as the fulcrum for the key levers B. These levers may be separated by
washers (Fig. 13) although it is not absolutely necessary because the rear ends of
said levers are held in fixed position by their connection with the bell cranks C.
A cylindrical rod c is also supported at its ends by the sides of the machine.
On the rod are hung the bell crank levers C which are made up of two separated
thin plates cc which are secured together and held in the proper relative position
by the two pins ect. The lower pin enters a substantially horizontal slot in the
end of the key lever, and the end of said lever lies between the two plates c³ c².
The upper pin enters a vertical slot a', in the under side of the corresponding
slide a, which likewise lies between the two plates c¹ c². When the key lever is
depressed the corresponding bell crank C is rocked, and its upper end moved
backward, thereby moving the slide a backward such a distance that the die A.
which is carried by said slide is moved out of the line of dies so far that it may be
moved transversely to the impression point without touching the other dies between
it and said point.
Extending transversely across the machine in front of the key levers, which are
of equal length, is a rock shaft d which is journalled in brackets d¹ which are
attached to the sides of the frame. To this rock shaft four levers D D, D' D'
are rigidly secured, two near its ends and two near the transverse centre of the
machine. A bar is secured rigidly to the two levers D D on one side of the
centre of the machine; and it lies beneath and in contact with all the key levers on
said side of the machine. Another bar is rigidly secured to the two levers DI D'
on the other side of the machine in line with the first named bar d³, and it lies
beneath and in contact with all the key levers on that side. represent two
bars which are arranged in line in front of the front ends of the key levers, and they
are rigidly connected with the levers D D and D' D' respectively. When any
key lever is pressed down it moves down the bar 3 beneath it, whereby the rock
shaft dis rocked and the bars d are moved beneath the ends of the other key
levers. At the same time one of the bars d passes over the end of the depressed
key lever. The front ends of the key levers are pointed and curved to permit this
action, as shown in Figures 14 and 15.
Pivoted to the sides of the frame adjacent to the levers D D' are the bell crank
levers H. The substantially horizontal arm of each bell crank is provided with a
sloth, into which extends a pin projecting from the adjacent lever D or D¹.
The other arm of said bell crank extends downward, and to it is attached one end
of a contractile coil spring h'. The other end of said spring is attached to the top
plate 4 of the frame at a point where, normally, the force of the spring is exerted
through the pivotal line of said bell crank. One effect of depressing a key lever is
to rock the rock shaft das before explained. This moves all of the levers D D',
which in their movement, by the connection above described, rock the bell cranks H.
The lower ends of the springs are thereby noved backward until their force is
no longer exerted through the pivotal line of the bell crank levers H, but to one

page_text: side thereof, whereby these springs exert their force to move the bell cranks still
further in the same direction. This movement of the bell cranks moves the
levers D D'. The bar d', which has been moved over the end of the depressed key,
presses on said key and compels it to move downward the complete distance
provided for that is to say, if the operator initiates the movement of a key, the
mechanism above described compels the key to complete its movement, and holds it
down until all of the movements of other parts of the machine which the depression
of the key initiates have been completed. At the same time the depression of any
other key is prevented by bars until the depressed key is returned to its normal
position.
The key is returned by means of a rod J, the forward end of which lies between
and is pivotally connected with the two middle levers D D'. Its rear end is
connected with a platej having a slot j¹ through which the main shaft G of the
machine passes. This plate rests on a collar g rigidly secured to said shaft, and a
cam g' on said collar is so placed that as the shaft revolves this cam will engage
with a lug on the under side of the plate j and move said plate forward. The
lug and cam g' are so placed relatively that the cam does not obstruct the
backward movement of the bar when the shaft is at rest. When the plate j
is moved forward the rod J rocks the levers D D' and the bar d lifts the
depressed key.
At the rear end of the machine is a transversely movable carriage, which carries
the impression receiving material. At the transverse centre of the machine
a longitudinally movable plunger I is mounted in a groove in the top of the
portion of the frame. A cap plate i is screwed on to the part 5, and the plunger
is held in place by this cap. A contractile coil spring is connected at its ends
respectively with a pin on the plunger, and with said cap plate, which spring
withdraws the plunger after it has been removed to make an impression of the die
behind it.
Between the carriage and the dies are the two guide rods e e', preferably made
of spring steel placed one above the other, extending transversely across the
machine passing through the sides of the frame. These rods may be tightened or
loosened as occasion requires by means of bolts which screw onto their ends.
Mounted on these guide rods are two shuttles,-one for each side of the machine.
Each of these shuttles is adapted to move from the side at which it is normally held
to the centre of the machine, and back again, and one of them does so move every
time a key is depressed. In so moving it carries with it the die which has been
moved out of the line by the before described action of the key, to the impression
point directly behind the plunger 1.
Each shuttle is composed of two parts E E¹. The part E' which is nearest the
centre of the machine, and which is termed the inner part, is the part to which the
power is applied to move the shuttle. The other part E (hereinafter called
the outer part) is that part which grasps and holds the die, thereby carrying said
die with it to the impression point in line with the plunger I and then back again
to its normal position. These two parts are connected by two contractile coil
springs e e, whereby, when the inner part E¹ is moved toward the centre of the
machine, the outer part E is dragged after it by means of the said springs.
The outer part E is composed of two plates ee having between them a groove in
which the rod e¹ lies, and an arm which is rigidly connected with one of said
plates and which has a hole in its upper end in which the rod e lies. The two
plates bang below the rod e' and in this depending part of the shuttle is a horizontal
slot e, open toward the centre of the machine. The dies A are cylindrical and the
end of the slot e³ is curved to fit these dies. A curved locking finger e is mounted
in a correspondingly curved groove at the end of the slot between the two
plates ee and a tail on said finger projects normally downward from between
the two plates. When this tail stands vertically, a die may enter the slot e³ aud
the curved finger offers no impediment, to its entry or exit. If, however, the finger
is moved so that the tail thereon is moved toward a horizontal position, as shown

page_text: in Figure 19, the said curved finger embraces the die and prevents its removal from
the slot in the shuttle. Projecting from both sides of the finger is a pin e,
which is adapted to engage with the shanks of the dies, for the purpose to be
presently explained.
:
Fastened to the inner part E of the shuttle is a spring catch e' which auto-
matically engages with a fixed projection 15 at the side of the frame, and thereby
the shuttle is held at the side of the frame until this spring catch is released.
The spring catch is released whenever a key is depressed by the following
mechanisin Pivoted to a stationary part of framework and on each side of the
machine are the rock shafts K. K, to each of which are attached two horizontal
arins k From these arms hang the links, the lower ends of which are
connected by a bar which lies over the rear ends of all the keys on the same
side of the machine. One of the links lies between two pins, which project
from the side of the frame, by which the said links are guided and caused to
move substantially vertically when they move at all. Secured to the rock shaft K
and extending downwardly therefrom is a second arm which is connected by
means of a link with a pivoted lever 48, the upper end of which lies behind the
end of the spring catch before referred to. The same parts are found on the
opposite side of the machine connected with rock shaft K. The bar is at some
little distance above the key levers, whereby said key levers may be moved a
considerable part of their throw before they engage with said bar. When they do
engage with it, they move it upward, thereby rocking the rock shaft K, or Kas
the case may be, and through the connections ab ve described, moving the lever k³
thereby causing the withdrawal of the spring catch on that side of the machine.
This releases the corresponding shuttle which is immediately moved toward the
centre of the machine. In its movement, the slot above referred to slips over
the die which has been projected by the movement of the key, the part of the
shuttle in which said slot is formed entering between the two shanks of the dic;
and said die is carried with and by the shuttle toward the centre of the machine,
the die case turning upon its pivot during the operation, as shown in Figures 23
and 24. As the die moves toward the centre, the shanks thereof become more and
more inclined to the vertical. These shanks strike against the pin & projecting
from the tail e of the curved finger e', and said tail is thereby moved out of the
vertical position, said finger revolving in its groove, whereby it locks the die in the
shuttle. When the die reaches the centre of the machine, it is caught in the curved
slots of the two connected arms LL' which are pivoted on bolt to the frame.
These two arms are so far separate that the shuttle passes between them and one
of them engages with the die between the shank a and the head end of the die,
and the other between the shank a² and the other end of said die, as shown in
Figure 18. The arms L L' then swing until they strike the stops or shoulders 12 1ª
on the fixed plates 13 13 between which the arms L L' lie; and when at this point
the die is at the impression point, and it is moved forward by the plunger 1, to
make an impression either in matrix material, or on paper or other like material.
When the die is moved by the plunger, the shuttle is moved with it, the spring
guide rods e e being bent backward by said movement. When the plunger
moves out of the way, the spring rods e e¹ move the shuttle forward and thereby
withdraw the die. While the plunger is moving forward and backward to make
this impression and to get out of the way of the die, the inner part E' of the
shuttle, to which the power to move it is applied, continues its movement for half
an inch, more or less, the springs e²e expanding during this movement.
portion of the shuttle then begins its backward movement and strikes the part E
of the shuttle, which it pushes before it, back to its original position. The interval
of time during which the front part of the shuttle is moving forward and backward
independently of the rear part, is sufficient for the impression of the die to be
made by the movement of the plunger.
This
The shuttles are moved respectively by the levers M M which are pivoted at
their front ends on the top of the posts 7 and 9. The rear ends of the levers M M'

page_text: are connected respectively by means of the links m² m³ with inner parts E¹ of the
two shuttles. A narrow horizontal guide bar n is fixed to the post 8 and to a
lug on top of cap plate i. A siide N surrounds and is guided by said bar n.
On the under side of the slide N is a cross bar n having a transverse groove n².
To the top side of the slide N a plate O is pivoted extending forward from its
pivotal point. A link m connects one side of the front end of this plate with the
lever M, and a similar link m' connects the other side of said plate with the
lever M. The connections between the ends of the links m m' and both the plate O
and the levers M M are adjustable; the pivots thereof being adjustable in slots
in said plate and levers M M³. When the slide N is moved toward the front of
the machine, and the shuttle on one side (say the right side) of the machine, is
held in its normal position, and the shuttle on the left side of the machine is
released, the last named shuttle is moved toward the centre of the machine by
the following action of the parts. The pivot m³ of the link m' in the lever M¹ on
the right side of the machine, is the fixed point by which this movement is
controlled. By the forward movement of the slide N the plate O is likewise moved
forward, and at the same time said plate is drawn toward the right of the machine,
on which this fixed pivot m³ is located, the link m moving about said fixed
pivot m³ as a centre. The plate O in moving toward the right side of the machine
causes the lever M to swing on its pivot on the post 7, thereby, as above stated,
moving the shuttle toward the centre of the machine, as shown in Figure 28.
When the slide N is moved backward, the parts reverse their movement and
return to the position shown in Figure 1. When the shuttle has reached the side
of the machine, the spring catch e engages with the fixed projection 15, thereby
holding the shuttle until again released.
The forward and backward movement of the slide N is occasioned by means of
pin 3 which projects upward from a crank g into a transverse groove n² in the
cross bar ; and as this crank is revolved, the slide N is necessarily moved forward
and backward. The said crank g is attached to a vertical shaft G to which a
constant force is applied tending to revolve it. Its continuous revolution is
prevented by the catches e' holding the levers M M' stationary as described. The
motor shown in the drawing for revolving the shaft G consists of a pinion g
secured to the shaft G; a gear t secured to shaft T meshing with the said
pinion a pinion t¹ secured to the shaft T, and a gear t2 meshing with said
pinion t. The said gear 2 is formed on the outside of a spring barrel which is
revolved by a spring S. Secured to the shaft G is a quick acting cam g, which
engages with the end of the plunger I and moves it forward sharply against the
end of a die, to cause the impression movement of said die. This cam comes into
action at the time when the slide N is nearest the front of the machine, which is,
consequently, at the same time that the shuttle has carried the die to the impression
point. As before stated, this cam acts upon the plunger to move it forward and
then gets out of the way so that the plunger may move backward in that interval
of time during which the inner part E¹ of the shuttle is moving forward and back
independently of the outer part E.
The carriage U is a plate which is mounted on the top horizontal side of the
plate 6 of the frame of the machine, a transverse tongue on the plate 6 entering a
groove in the under side of the carriage whereby the latter is guided. Projecting
downward from the rear edge of the carriage is a plate u, in the front edge of
which a rack is formed. Engaging with the rack is a pinion u² pivoted on a
vertical stud u³, which stud is screwed into the under side of the plate 6. Secured
to the pinion is a ratchet wheel u. Pivoted concentrically with the ratchet wheel
is a lever us which carries a spring pawl u which is held in engagement with said
ratchet wheel u by the spring . A transverse rock shaft W is mounted on the
frame of the machine below the carriage. To it are rigidly secured two upwardly
projecting arms ww, having their ends connected by bars w¹ w¹, which are secured
to said arms and extend across the machine just in front of the projections a¹º on
the die cases.
These bars w¹ w³ are connected by means of a universal link to²

page_text: with the lever u³; so that when said bars w³w' are moved backward, they cause,
through the said connecting link, a backward movement of the lever us whereby
the pawl slides backward on the ratchet a number of teeth corresponding with
the amount of movement of said lever. When the said bars w to' are returned to
their normal position, they draw the lever u with them. In this movement the
pawl engages with the ratchet teeth, thereby revolving it and the pinion u² and
causing a movement of the carriage the greater or less according as the described
backward movement of said lever has been greater or less. This constitutes the
feeding of the carriage. The movement of the carriage takes place immediately
after the impression of the die is made, and, since one of the uses of the machine
is to make a matrix in which a linotype may be cast which will simulate a line
formed of type set by hand, it is necessary to have a differential feed; that is to
say, that the carriage shall be moved after each impression distances proportionate
to the width of the letter of which the impression has been made. To secure this
result, a stud a projects rearward from each die case. The length of these studs
is proportionate to the width of the letter on the dies. The longest studs, which
will be on the cases which carry the widest letters, almost touch one of the
bars ww when in their normal position. The narrower the letter, the shorter the
stud on the corresponding die case, and consequently the greater the distance
normally between the end of the said stud and said bar. As before explained,
every die case is moved by the movement of its slide the same distance rearward
as every other die case is moved. It therefore follows that the longer the stud, the
greater will be the movement of the bars w' w¹ and of the lever ³, and consequently
the greater will be the movement of the ratchet wheel occasioned by the return
movement of the said lever.
This return movement of the bars ww¹ to their normal position is occasioned by
a rod w having a hook which engages with a pin w fastened to the two middle
arms to which said bars w¹w are attached. This rod is secured to the slotted
plate which, as before stated, is returned to its normal position by the operation
of the cam g; and in returning to this position the hook on the end of the rod w
likewise returns the arms ww and the bars w¹ w¹ which they carry, to their normal.
positions.
This machine is intended especially for making impressions in wood blocks.
A hopper 40 containing a supply of blocks is mounted on the carriage U. Mounted
on the carriage adjacent to the hopper is a standard Y having ears yy through
which a vertically movable rod y' passes. A coil spring y' surrounds this rod and
presses against the upper ear and against a collar on the rod. To the lower end
of the rod is secured a pressure block y in which are mounted a series of rollers y
having their peripheries threaded and also fluted longitudinally. A push bar
fixed to the frame is adapted to enter a slot in the lower end of the hopper, and
when the carriage is moved to the left it does so enter said hopper and pushes the
lower matrix out through a slot therein and underneath the rollers y' in the pressure
piece above described; and this matrix in turn pushes the matrix in which the
impressions have just been made out from under said pressure piece. The surface
of the rollers is formed in the described manner so that the wood block in passing
under them will be caused to slide backward against the standard Y.
Journalled to the left side of the frame is a rock shaft R, having at some con-
venient point an operating handle r. At the rear end of this rock shaft an arm r
is rigidly secured. It projects upward and its upper end is connected by means of
a link with a bar r. This bar is connected with the rear edge of the carriage
by two parallel links 5. A shoulder on the carriage is adapted to be engaged
by one of said parallel links and a contractile coil spring which, connected at its
ends with said carriage and bar, exerts its force to so move the bar that said
link is brought into engagement with said shoulder. The bar * lies just behind
and close to a pin us on the pawl u. When one of the links is in contact with
the shoulder, the bar is at its greatest distance from the said pin and does not
touch the same, and the parts are in this position when by the operation of lever r.

page_text: the carriage is moved to the left; but when the lever » is moved toward the right,
it moves the bar, which in its movement presses on the pin on the end of the
pawl and lifts the pawl out of engagement with the feed ratchet.

The purpose and mode of operation of the above described mechanism is as
follows: When a matrix has been completed, the handle is moved to the left.
This causes the carriage to be moved toward the left to the end of its path when it
strikes the stop which stops it. During this movement the plate V has entered
the lower end of the hopper and pushes a matrix block out of the hopper and
under the matrix holder where it is ready to be operated on by the dies, the matrix
which has just been formed having been forced from under said holder as before
explained. The handler is then moved to the right. The first effect of this move-
ment is to move the bar r to the right, which bar in so moving moves toward and
against the pin in the pawl us, which pawl is thereby lifted from engagement
with the ratchet. The ratchet wheel may then be revolved freely as the carriage
is moved back to the right side of the machine. The continued movement of the
handler to the right causes the carriage to be moved to the right and to the starting
point.
The paper holding device is most clearly shown in Figures 29, 30 and 31.
A base 20 is pivoted to two ears on the carriage U. To it are secured two
sides 21, 21. A rock shaft 22 is journalled in the upper ends of said sides.
A roll 23 is journalled to said sides; and two triangular plates 24 are secured to
said rock shaft. To these two plates are journalled the two paper rolls 25, 26.
On the side of one of the plates 24 is a projection 29 against which the lever 27 is
adapted to engage, the lever being pivoted on said rock shaft. A coil spring 28 is
secured at its ends to one of the sides and to the lever 27. When the parts are in
the position shown in Figure 31, the spring 28. acting on the lever 27, causes it to
press against the projection 29, whereby the roll 25 is held in engagement with the
roll 23. If, when the parts are in this position, the roll 23 is turned by means of
the finger piece 23, the roll 25 will be revolved. If the lever 27 is thrown over
to the right until it strikes the other side of the projection 29 the roll 26 is thrown
into contact with the roll 23, the latter roll being covered with sand paper or other
like material.
The paper 30 is wound around roll 26, passes down under the base, up over its
front edge, over roll 23 and around roll 25.
If it is desired to use the machine for a typewriter to print on the paper,
the base 20 is allowed to swing down until it rests on the carriage in a recess
in the top side thereof. The front edge of the base will then be in the proper
point to serve as a platen against which the paper rests when impressions thereon
are being made.
A lever 31 which is pivoted to an arm 32 extending rearward from the base,
engages on top of an arm 33 projecting rearward froin the carriage, and thereby
holds the base down in the position referred to.
In a recess on the under side of the base are two ribbon rolls 34, and the ink
ribbon which is wound on said rolls, passes horizontally over the front edge of
the base outside of the paper, being held out of actual contact with said paper
while being held in proper position over the same by the grooved projecting
corners 35 of said base.
The machine may, by reason of its adaptability to use as a typewriter, be
employed to print the copy which is to be followed in making the matrices; and
if the copy be prepared with no lines longer than the standard length of the
linotype required, it will assist an operator, who is making matrices on the machine,
to justify his line by the method set forth in my previous Patent No. 21143
of 1893.
When the paper holding device is being used as a copy holder, the base of the
holding device is raised, and upheld by the engagement of the said lever 31 below
the arm 33. A slide 36 is now pushed into an appropriate groove in the carriage,
so as to cover the depression therein into which the base 20 projected when in the
