Improvements in Matrix Making Machines.
A communication by CHARLES SEARS, of 1221, Lexington Avenue, in the City of
Cleveland, County of Cuyahoga and State of Ohio, United States of America,
Gentleman.
1, 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 and 323 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 object of the invention is to produce an improved machine with which, by
the operation of its finger keys, a series of letters and printing characters,
corresponding with said keys, may be impressed, one by one, into a strip of wood
or other equivalent material, in predetermined relation to each other, thereby
forming a matrix which is adapted to be used as a mould to produce a cast of such
letters and characters. Each complete matrix, which the machine shown in the
drawings is specially adapted to make, may contain all of the letters and the
characters intended to appear in one full line of printed matter; therefore the cast
made therefrom will be what is commonly known as a linotype, that is to say a
single type, equal to the line in length, bearing on its printing face all of the
characters, properly arranged, which are intended to appear in said line. The
operation of the machine is independent of any particular material to be used to
receive the impressions, but the inventor has been able to obtain satisfactory final
results by using strips of wood, with the fibres lying in the direction in which the
impression is made.
In this machine he employs a revolvable cylinder which carries one or more
rows of radially movable dies. This cylinder is revolved constantly by suitable
mechanism during the operation of the machine. Mounted concentrically with said
cylinder is a swinging frame which carries the matrix, and provides means for
causing said frame to move at intervals in fixed relation to the cylinder, and with
some predetermined die in such relation to the matrix that its impressions may be
made therein while the frame and cylinder preserve their fixed relation. Means
are also provided, which, in the construction illustrated in the drawing, are
operated for the intended purpose by the swinging of said matrix carrying frame,
with which the proper die is moved radially outward from the die wheel and
impressed into the matrix. The machine also contains novel means for holding the
dies in the die wheel in such manner that they will not be caused to fly outward by
the action of centrifugal force, but are nevertheless permitted a slight lateral
movement which enables them to accurately enter the guide above the matrix.
The machine also contains a matrix holding device which is acted upon by a
projection on the forward side of each die, as said die moves outward, thereby
moving the matrix forward, just before the die makes its impression, a distance
equal to the width of the letter on the die plus the normal space between the
letters.
The machine also includes a type-writer attachment and means for operating it
simultaneously with the operation of a die, whereby a fac-simile reproduction of the
impression made by the die is printed on a paper; and the paper carrier is so placed
and actuated that the operator can instantly see what character has been made and
whether it is in the proper relation to the preceding character. In order that the
spacing of the characters in the matrix and on the paper shall be alike, a suitable

page_text: The cylinder is provided with a plurality of rows of dies, and the dies in each row
may have characters of a different style or size from the characters on the dies in
the other rows, and means are provided for changing the relative position of the
cylinder and die operating mechanism and matrix, so that the dies in any row may
be employed to make the impression.
The machine is also provided with means for feeding one matrix block after
another into the matrix carrier without stopping the machine.
And it also contains certain mechanism intended to act as safe guards to prevent
the improper and injurious operation of the machine.
The drawing shows a complete operative machine having the features of con-
struction hereinabove described in general terms, as well as other novel features, all
of which will be hereinafter described.

Referring to the parts by letters, A represents the bed plate of the machine.
At one end of this bed plate is secured a standard a, having at its upper end a long
sleeve a'. The driving shaft a² is journalled in, this sleeve. At one end of the
shaft are the fast and loose pulleys a³ a upon which the driving belt runs.
B represents a hollow cylinder having, at or near its longitudinal center, a hub b
which is keyed or otherwise fixed to the driving shaft.
Near one end of the cylinder are one or more rows of radially movable dies C,
and near these dies are an equal number of rows of types F which project radially
from the cylinder. Set below the surface of the cylinder, in appropriate longitudinal
grooves, are the longitudinally movable rods D which pass through the end
flanges b b of the cylinder. In a part of their length at least, these rods are made
square (as at d) or of any other angular form, and the grooves in the cylinder in
which they lie are similarly shaped whereby the rods are prevented from turning.
On the ends of these rods which lie outside of the right hand flange b¹ are the
heads d', the purpose of which will be hereinafter explained.
Projecting radially outward from each rod is a bevelled arm d². These arms
project from the cylinder in a spiral, and each is so placed that it will, as the
cylinder is revolved, strike its associated bar e³ when the same is moved out by the
operation of its key.
The cylinder is made of two separable parts which are connected by means of
bolts as shown in Figure 3. The right hand end of the cylinder is that part of the
cylinder from which the arms d² project, and is permanently fixed in the described
relation to the other parts. The left hand end of the cylinder carries the dies C,
and type F, and may be removed and another similar part substituted therefor
whenever one desires to use a different size or style of type.
When in their normal condition, the left end of the rods D do not project beyond
the left end of the cylinder, but each is made to project therefrom to cause the
engagement of the swinging frame (to be hereinafter described) with the cylinder,
by the operation of its associated key.
The key board and the operating parts connected therewith are supported by two
brackets as a which are attached to the bed plate. A cylindrical rod e is secured
to said brackets and extends through the left bracket a. Between the brackets,
the keys E are loosely hung on the rod e, being separated by washers. e¹ represents
a round rod which is fastened at its ends to the brackets a a. On it are mounted
the bell crank levers 2. One arm of each of these levers is connected with a
sliding bar e which is supported in and guided by the cross piece e³. This cross
piece is connected at its ends with the brackets a a. The other arm of the bell
crank lever is connected by means of a link et with one of the keys. The springs e,
each connected with a key and with a rod e', exert their force to return the parts to
their normal position as shown in Figure 7.
An angle lever e³, is mounted loosely on the rod e just to the left of the
bracket a. A bar e which lies against the upper side of the keys is rigidly
connected at one end to the upper arm of the lever es, and at the other end to an
arm similar to said upper arm, which is also loosely mounted on the rod e near the
bracket a*.
J represents a lever mounted loosely on a pin secured to the bracket a. Its
lower end lies in a position where it is adapted to enter one of the notches j in a
bar J. Its upper end is in contact with the lower arm of the bent lever e³.
Mounted in the brackets aa is a locking bar eo to one end of which a rigid
arm el is fastened. A link e¹ is pivoted at one end to the lower arm of the bent
lever and a pin on the arm el passes through a slot in said link e". A coiled

page_text: spring J is stretched between and connected to the arm e" and upper end of the
lever J.
Secured to the locking bar eo is a flange e¹³ which lies directly in front of the
lower edges of the bosses E' on the under side of all of the key levers. Each of
these bosses is notched horizontally as shown in Figure 7.
The mode of operation of the key board mechanism, above explained, is as
follows. When a key is depressed by the operator the key bar e³ is, by means of
the connecting mechanism described, thrust outward into the path of the bevelled
arm d with which it is intended to co-operate. The movement of the key lifts the
bar e which causes the bent lever e to be rocked. The lower end of this bent
lever engages with the lever J which is thereby rocked and its lower end forced
into one of the notches j, if the bar J¹ is in the right position to permit the move-
ment. If it is not, and the lower end of the lever J cannot enter one of the
notches j, the key E cannot be depressed far enough to throw out the key bar e³.
This is a safeguard to prevent the operation of the machine, unless the guide for
the dies C is in such a position as will permit one of the dies to enter it smoothly,
as will be presently explained. Before a key is struck, the pin on the arm ell
abuts against the end of the slot in the link el, and the locking bar el is thereby
prevented from so rocking as to throw the flange e¹³ toward the key bosses E'; but
when the bent lever es has been moved as before explained, the arm ell is permitted
to move and is moved by the action of the spring J2. The flange e¹³ on the locking
bar enters the notch in the depressed key and thus holds said key down until it is
released in the manner to be described; and at the same time the said flange
moves beneath the bosses on all the other keys and prevents any of them from being
depressed until the locked key is released.
The key is released and the parts returned to place by means of a bell crank
lever L, which is pivoted to the under side of the bed plate A, an arm e", which is
rigidly attached to the locking bar, and a link el, which connects one arm of the
bell crank lever L with said arm e4. The bell crank lever L is rocked, after an
impression has been made, by the movement of a bar I, thereby causing the locking
bar el to be moved back with the result of disengaging the flange e¹³ from the key
bosses and returning said locking bar to its first position. The spring J2 will now
draw upon the lever J which in moving to its first position likewise moves the
bent lever e and the bar e' attached thereto back to their normal positions.
A sliding carriage H (shown separately in Figures 27 and 28) is mounted on the
bed plate in suitable guide ways. This carriage supports the matrix carrying and
feeding mechanism, the mechanism for operating the dies, and numerous other
parts of the machine to be hereinafter explained. At one end of the carriage is a
standard h, and to this standard a horizontal arbor h' concentric with the cylinder B
is secured.
A swinging frame is mounted on this arbor and is adapted to swing freely back-
ward and forward in the manner and for the purpose set forth. Around the hub G
of the frame, a coiled spring G₁ is placed, and the ends of this spring are connected
respectively with said hub and with the standard h. When the frame is moving
forward in fixed relation with the cylinder, the coil is tightened, whereby, when
the frame is released, it is moved by the spring back to its first position. The
frame consists of three essential parts, viz., the hub G, the bed plate g which
lies beneath and more or less nearly parallel to the face of the cylinder, and an
arm gl which rigidly connects said parts. The matrix holder is secured to the
bed plate, and suitable mechanism is provided whereby the frame is connected with
the revolving cylinder when the selected die is directly over the matrix,
and the frame and cylinder are moved in fixed relation with each other for a
time; during which time the die is moved outward and its impression made in the
matrix..
The mechanism shown for making this connection consists of the following
combination and arrangement of parts. Fixed to the bed of the frame is a
bracket. A rock shaft 93 is journalled in this bracket and in the arm g' of the

page_text: frame. Rigidly connected with this shaft are two arms g₁ g; and two rods g³ g°
are connected at their ends to said arms and pass through slots in the arm gl and
bracket g², as shown in Figures 6 and 14. Loosely pivoted on the rod g' is a
plate which lies close to the end of the cylinder Band is held in the proper
relation thereto by a pin g8, which projects into the cylinder and bears against its
inner wall; and two flanges 9 g which engage with the sides of the periphery
and flange 6 of the cylinder. The plate has a shoulder 10 against which one of
the rods D strikes when it has been moved out by the described action of its
associated key. To prevent recoil, a latch g¹¹ is provided which is also loosely
pivoted on the rod 9 and is held in operative relation with the plate g by the head
of a screw which passes through a slot in said plate and screws into the latch. The
upper end of the latch is bevelled, whereby the rod D which is projecting from
the cylinder is enabled to crowd back the latch until such time as the rod strikes
the shoulder glo, at which instant a spring 12 forces the latch over said pin, as
shown in Figure 14.
Projecting downward from the front edge of the bed g is a bevelled lug g¹³, and
pivoted to the carriage H is a spring actuated arm, which, when the swinging
frame is returned to its normal position, is automatically pushed back by said lug,
and then springs beneath it and prevents the forward movement of the swinging
frame. Secured to the rock shaft y3 is a toc g" which is adapted to push the spring
arm from beneath the lug gl when the rock shaft is rocked. A spring gib
secured at one end to the bed g is curved under the rod y' and serves to hold
the rock shaft and parts connected thereto in the position shown in Figure 14. The
plate g is cut away for a part of its length in front of a part of the end of the
cylinder, whereby one of the rods D may be so moved as to project from the end of
the cylinder. The upper end of the plate curves away from the cylinder, so that if
one of the rods has by accident been moved out from any other point except that
opposite to the cut-away part of said plate, said rod will engage with the inclined
face of said plate and be thereby thrust back again.
When, by the operation of one of the keys, a rod D has been caused to project
from the end of the cylinder, it engages against the shoulder 10 on the plate 9 and
it is latched by the latch g". The first effect of this engagement is to rock the
rock shaft g³, and this causes the toe g" to push back the spring arm ², thereby
releasing the swinging frame. The frame then moves in fixed relation with the
cylinder for about one sixth of its revolution. The parts are in such relation to
each other that, when the swinging frame and cylinder are so moving, the die
corresponding to the key which was struck to move out the projecting rod is
directly over the opening in the matrix holder; and during the time the frame and
cylinder preserve their fixed relation, the said die is moved out, its impression is
made in the matrix, and it is retracted by the mechanism provided for this purpose.
When this has been done, a bevelled arm a', fixed to the sleeve a', engages
behind the head d¹ of the projecting rod D and draws it into the cylinder. This
releases the swinging frame, which is then returned to its first position by the
spring.
In order that the swinging frame may not be unduly strained by the pressure of
the die upon the matrix, a friction roller 18 is journalled to the carriage H directly
beneath the opening in the matrix holder when the die is making the impression,
and a flange 20 on the under side of the bed of the swinging frame rides upon the
roller.
Mounted in guides 9 on the ends of the hub G of the swinging frame is a
radially movable plunger R which is slotted in both directions. In the slots which
are longitudinal with reference to the machine, lie the retracting fingers rr
which are pivoted to said plunger. Passing through the transverse slots is
a bar, secured rigidly to the swinging frame, having bevelled upper and lower
edges.
On the face of the bracket 3 secured to the head is the cam groove h*, into
which a pin r², secured to the plunger, projects. When the swinging frame is

page_text: stationary, this pin lies at the extreme right hand end of the groove, and below the
spring actuated switch ; and the bar r lies between two lugs on the
fingers below their pivots, whereby said fingers are held apart at their lower or
grasping ends.
When the swinging frame begins its movement, the pin 2 travels in the down-
wardly inclined part of the groove thereby moving the plunger down, the end
of said plunger striking the end of the die directly beneath it. At substantially
the instant of contact the lower lugs 8 move off the bar r', and the upper lugs.
engage with the upper bevelled edge of said bar, and thereby the fingers are made
to rock upon their pivots and grasp the said die just below its head c³ on its inner
end. The further downward movement of the plunger moves the die outward to
make its impression in the matrix. The further movement of the swinging frame
causes the pin to enter and move in the upwardly inclined part of the cam
groove, thereby moving the plunger up and retracting the die. When the die
is fully retracted, the lugs on the upper end of the fingers move off the bar
and the lower lugs engage with the lower edge of said bar, whereby the fingers
are opened and the die released. When the swinging frame has completed its
forward movement, the plunger is fully retracted and the pin is in the extreme
left hand end of the cam groove. A spring actuated pin 4 with bevelled or
rounded point enters a slight depression in the plunger and prevents it from
dropping by its own weight, and thus, when the swinging frame moves backward,
the pin travels in the upper part of said groove passing over a spring switch ³
to the position first described.
Below the bed plate A a sliding bar I is supported in brackets a³, a³, through
which it may be caused to slide in the following manner. A coil spring i surrounds
the bar and lies between the enlarged end 3 and the bracket as. The other end of
this bar is permitted to play vertically in a slot in the bracket a. On the under
side of the forward end of this bar is a shoulder which, as the bar is moved
forward, strikes a pin on the arm of the bent lever L, thereby rocking this lever
sufficiently to release the keys as heretofore explained. When this lever has been
moved far enough, an incline on the under side of the bar I strikes the bracket a
whereby the bar is lifted and the lever L is released; and this lever, through the
action of the spring J2, immediately flies back to its normal position. An arm is
rigidly secured to the bar and extends upward to a point where it is struck by a
bar or shoulder g" on the under side of the swinging frame, when the frame is
returning to its normal position. The frame moves the bar, as and for the purpose
specified, while the bar acts as a spring buffer to check the backward movement of
the frame.
The manner of securing the dies in the cylinder is peculiar, since it is desirable
that they be capable of yielding slightly when they enter the guide by which they
are accurately centered on the matrix. To secure this result, rubber thimbles or
bushings c are fastened in radial openings in the cylinder, and these bushings exert
a pressure upon the dies which pass through them sufficiently to hold said dies
stationary during the movements of the wheel when they are not being acted upon
by the plunger. To avoid wear upon the rubber and friction in the sliding move-
ments of the dies, the thin metal plates c' are interposed between the rubber bush-
ings c and dies, such plates exerting no pressure upon the dies except such as is
caused by the rubber bushings surrounding them.
The matrix holder T is secured to the bed of the swinging frame. It is provided
with two sides t t', between which the matrix slides, a bottom t2, and a top plate 3,
having a funnel shaped opening t, which serves to guide and truly center the
entering point of the die should it start at one side of its true course.
The matrix indicated by S, and shown in Figure 31, is of any suitable height,
although it has been found convenient to make them type high, and a trifle longer
and thicker than the linotype to be cast therefrom.
U represents an inclined matrix hopper, which is secured to the carriage H,
in which is placed a number of the matrix blocks. When the swinging frame

page_text: is stationary, the entrance between the plates tt' of the matrix holder is directly
in line with the bottom of the hopper. On the carriage are guides upon which
a slide u moves; and to this slide an arm u is attached and so placed that
when the slide is moved to the left this arm engages with the lowest matrix
block in the hopper and pushes it into the matrix holder, thereby pushing out
of the holder the matrix in which the impressions have just been made. A lever u³,
pivoted to the carriage, engages with the slide and affords means for moving it.
In the operation of the machine, the matrix block is fed by the action of the die,
in moving out against the matrix, a distance equal to the width of the character on
In this manner the
the die, plus the normal space between two successive letters.
impressions are automatically spaced according to the varying widths of the various
letters and characters employed. This is a very important feature of the machine
as it results in the production of matrices in which the matter impressed will
exactly resemble the same matter set in type.
The construction and arrangement of parts for properly feeding the matrix block
will now be described. The dies are all of the same size, and the different sized
characters thereon are all arranged with their rear or right hand ends at equal
distances from the right side of their dies. Therefore, when the dies are in the
cylinders, the rear or right hand ends of all the characters lic in the same vertical
plane. On the forward side of each type die, and integral preferably therewith, is
a projecting boss 2 which when the die descends strikes the inclined face of a
slide to, which is mounted on the matrix holder. These projecting bosses c² are
relatively proportionate to the width of the letters on the several dies; and, in
the form shown, each projection is equal to the width of the letter plus the
normal space between two adjacent letters; thus cach die, in descending upon
the matrix, moves the slide a distance equal to the width of the letter thereon plus
the inter-letter space. At the instant of this movement, the matrix block is in
the embrace of devices connected with the slide, so that it moves in unison with the
slide, as will be apparent from subsequent description. This movement of the
matrix block takes place immediately before the die begins to make its impression
thereon, said die having some distance to move after it moves the slide. When the
die is withdrawn, a spring te returns the slide to its first position.
18
18
The devices by means of which the matrix block is grasped and compelled to
move with the slide will now be described. Upon a concave surface of the
carriage are cam grooves 6. In a guide on the swinging frame is a sliding bar g
having a downwardly turned pin which enters said grooves. These parts are
shown clearly in Figure 19. Secured to an arm which is attached to the slide t",
a spring plate t having prongs to on its end. When permitted to move freely, this
spring plate stands in such a position that the prongs do not touch the matrix block.
Pivoted to an ear to on the pressure piece t¹ is a bell crank lever t, and one arm of
this lever is connected by the link 12 to the sliding bar 918. On the other arm of
the lever a friction roller t¹³ is placed which is adapted, when the lever is rocked,
to press the spring plate t' toward the matrix block and to cause the prongs thereon
to strike into said block. If the slide be moved when the parts are in this position,
the matrix will of necessity move in unison with it. When the lever is rocked in the
opposite direction, the spring plate t automatically withdraws its prongs from
the matrix block. The pressure piece t¹0 is fastened to one end of a stiff piece
of spring metal, which is fastened at its other end to one of the sides of the
matrix holder. Said pressure piece has a roughened surface at t¹ which is
adapted to strike against the side of the matrix block; and an overhanging
finger t¹ which rests on the edge of the top face of the matrix block. A bracket tie
having an inclined surface is secured to the matrix holder and lies above and in
contact with an inclined surface on one arm of the lever t¹¹.
18
When the swinging carriage begins its movement, in fixed relation to the cylinder,
the pin g on the sliding bar g is at the front end of the cam slot 46 on the
carriage, and neither the pressure piece to nor the spring plate is pressing upon
the matrix block; but when the pin 9 reaches the incline at h², the bar g¹8. is

page_text: moved, the lever " is rocked, and the prongs on the spring plate t are forced, as
above explained, into the matrix block. At this instant, the boss ² on the die
begins to move the slide t. The feed movement of the slide has been completed
before the pin 19 strikes the incline at h³, which moves the bar 918 in the opposite
direction, thereby rocking the lever " and permitting the retraction of the
spring plate t'. It also causes an incline on the lower arm of said lever t¹ to strike
an inclined surface on the bracket 16, whereby the pressure piece to is forced
sidewise and downward against the matrix block, thereby forcing said block
against the opposite wall and the lower plate of the matrix holder, where it is
held until the die has made its impression in the matrix and the frame swings
backward, bringing the pin g against the incline ³, which causes the pressure
to be released. The matrix holding, feeding and clamping mechanism is clearly
shown in Figures 19, 20, 21, 22, 23 and 24.
It is preferable to place the dies bearing the lower case letters and some
other characters in one row on the type wheel; those bearing the capitals etc. in
another row; those bearing the lower case italics in a third row; and those bearing
the capital italics in a fourth row. Then by making the cylinder and the swinging
frame relatively movable, any one of these series of letters may be used at will.
This result is secured by the movement of the carriage which carries the swinging
frame, and the parts connected with it (and in fact nearly all of the parts of
the machine except the cylinder and key board mechanism as before explained).
The carriage is moved by means of a lever O pivoted to the main frame. It is
provided with a latch 02 adapted to engage with the notches in the plate O', which
notches are so arranged that, when the latch engages with one of them, one of the
rows of dies is in the plane of the plunger R and guide t* of the matrix holder.
As a safeguard to prevent injury of the parts by reason of any failure to properly
lock the carriage, a bar J', having four notches j each adapted, in certain positions
of the carriage, to receive the lower end of the lever J whenever a key is struck,
is secured to the carriage. If the carriage is not in one of the four correct and
operative positions, the lever cannot enter one of the notches ; and the key
cannot therefore be depressed far enough to produce any effect on the other parts
of the machine.
In this movement of the carriage, the plate and latch 9" slide freely on the
rod 9 always preserving the same relation with the cylinder without affecting their
operative connection with the swinging frame.
The machine is also provided with a type-writer attachment which will now be
explained, whereby a proof or type-written fac-simile of the impressions made in
the matrix block is simultaneously made on paper which may be read by the
operator.
Fixed to the cylinder, and projecting radially therefrom, are one or more fonts of
type F arranged in rows which correspond to the rows of dies heretofore explained.
These type are preferably made of rubber, and are set into sockets in the cylinder,
but project therefrom far enough to extend through the funnel shaped guide, to be
hereinafter explained, and against the paper behind it. Abreast of this part of the
cylinder is a frame M which supports the laterally movable vibrating paper carrying
frame.
Two brackets V V₁ are secured to the swinging matrix carrying frame; and to
these brackets are rigidly fastened the four bars V2 V3 and V₁ V. These four bars
are likewise connected to a yoke V whereby they are held in fixed relation to each
other. To the bars V V the two side pieces m m¹ are rigidly fixed, and to the
upper ends of said side pieces a horizontal bar m² is fixed. A frame M¹ consisting
of the side pieces m³ m and a connecting cross bar m³ is pivoted at m³ m by pivots
to the side pieces m m¹, whereby said frame may be swung toward and from the
cylinder.
N represents a laterally movable frame which is mounted and adapted to slide
upon the bars V³ m² m². The upper part of this frame is pivoted to the lower part
by pivots in line with the pivots m m³, whereby it may swing toward the cylinder

page_text: in unison with the frame M. To the upper ends of the side bars n n' of the
laterally movable frame N are mounted the platen roll n² and the rolls n³ n* n³ for
holding and feeding the paper and the copy.
An arm P composed of two parts pivoted together is fastened to the bar V. On
the upper end of the upper part is a funnel shaped guide P' which is adapted to set
down over one of the types F and guide it against the paper on the platen. The
upper part is pivoted to the lower part so that the funnel shaped guide may swing
away from the type when the cylinder is moving independently of the swinging
matrix carrying frame. A spring P2 produces this backward movement which is
only sufficient for the intended purpose. On one side of the vibrating frame M¹ is
an arm m⁰ to which one end of a spring m' is connected. The other end of the
spring is connected with the side piece m¹ and the function of the spring is to swing
the frame M away from the cylinder.
On a
projection m from the other side of the vibrating frame is an arm m³ to
which is loosely pivoted a lever W. The lever is free to swing in one direction
without any effect on the described mechanism; but when swung in the opposite
direction, its upper end strikes said projection m³ and swings the frame M¹
toward the cylinder. In this movement the frame strikes the arm P bearing the
funnel shaped guide P¹, forcing it over one of the type which is then impressed
upon the paper.
When the swinging matrix carrying frame has been connected with the cylinder,
as heretofore explained, and is therefore moving in fixed relation thereto, the
type-writer attachment being supported by said swinging frame is moving in
unison with it. A bent arm is secured to the standard h, and in each forward
movement of the swinging frame, the lever W strikes this arm, thereby causing
the paper carrying frame N to be moved toward the cylinder with the above
described result. The imprint upon the paper is made at about the same instant
that the die is being impressed in the matrix, as shown in Figure 4. The continued
forward movement of the matrix carrying frame frees the lever W from its
engagement with the arm h; and in the return movement of said frame the
lever W is turned back and passes said arm / without any effect on the other
mechanism. A spring W₁ returns the lever to a position where in the next move-
ment of the frame the same action is repeated. Immediately after the lever W
passes the arm, during the forward movement of the matrix carrying frame, the
spring m² swings out pivoted frame M¹ and N so that the operator can see whether
the correct letter has been printed on the paper.
To the upper end of the paper carrying frame are journalled the platen roll n²
and a roll n for holding the copy, and two rolls n³ n³ which serve to hold the
two pieces of paper on said rolls. The inking ribbon rolls n n' are carried by
the arm P, and the ribbon n³ passes between the funnel shaped guide and the
platen roll.
The paper carrying frame is connected with the matrix by mechanism which will
now be described, whereby the frame is fed along equally and simultaneously with
the matrix. Fastened to the laterally moving paper carrying frame is an arm N¹
which passes between the two bars V2 V3 whereby it is held in proper position
relative to the parts it is intended to engage with. On its outer ends are secured
two small rods n° no between which a pin Y projects. This pin is attached to a
slide Y which is suitably guided in a path parallel to that travelled by the matrix.
Pivoted to this slide is a spring actuated arm Y2 having prongs on its end which
project through the side wall of the matrix holder and stick into the matrix block.
When, therefore, the matrix is fed along as before explained, it drags the paper
carrying frame with it.
When the matrix is fed along to the position to receive the last letter of a line,
the bevelled end of the arm Y2 strikes against the bevelled surface at t¹ on the
matrix holder T, whereby the said arm Y is swung outward enough to withdraw
from the matrix block the prongs on the end of said lever. The paper carrier may
now be moved back to its first position by hand, or by suitable mechanism which
B

page_text: may be provided for the purpose. In moving backward, the paper carrier draws
back the slide Y'. In this backward movement of the slide, a pin Y³, depending
from the spring arm Y2, engages on the outside of the rail Z which holds the
prongs away from the new matrix block which has been introduced into the holder;
and when near the end of its backward journey, the pin slides up the inclined
surface Zon said rail, thereby swinging the arm Y2 outward and applying tension
to the spring which actuates said arm. When the pin is moved off this incline
surface, the spring causes the arm Y2 to fly down with such force that the prongs are
imbedded in the matrix, thus making connection, as before explained, between said
matrix and paper carrier.
