MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 508,248, dated November '7, 1893.

Application filed April 25, 1892.

To all whom it may concern:

Be it known that I, CHARLES SEARs,a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Matrix-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a revolving cylinder, which carries one or more rows of radially movable dies, a movable matrix carrier which is adapted to be moved at intervals in fixed relation to the cylinder, and any selected one of the dies carried thereby, which relation is determined by the depression of a finger key corresponding with the selected die, and mechanism for causing an impression of said die in the matrix to be made during the time the cylinder and matrix carrier maintain said fixed relation,

The drawings show in all its detail a complete and operative machine containing my invention. Some of the parts of the machine shown are substantially the same as are shown and described in Letters Patent Nos. 475,804, 475,805, 475,806 and 475,807, granted to me May 31, 1892; indeed the machine shown in this application is a development of and improvement in many respects upon the ma- The principal improvements which the machine hereinafter described' embraces relate to the mechanism for moving the matrix carrier in fixed and predetermined relation to the'cylinder and the selectin'g die; to the die moving mechanism; to the mechanism for changing the relative position of the matrix carrier and the several rows of dies carried by the cylinder whereby the dies in any row may be employed to make the impression; to

for'feeding one matrix strip after another tended to prevent the improper action of the machine as I will hereinafter describe ;all of whichimprovements will be definitely pointed out in the claims.

The objects of all these improvements in $eria1No.430,5 73. woman.)

tion to each other and the other parts of the machine will thereby be more clearly understood.

Fig. 31 is a perspective View of a matrix partially finished.

In the drawings, three principal scales are used. Figs. 1, 2, 3, 27, 28, 29 and 30 are quarter size; Figs. 4, 5, 6, 7, 19 and 25 are half size; and Figs. 8,9, 10, 11,12, 13, 14,15, 16, 17, 1s, 20, 21, 22, 23 and 24 are full size; Fig. 26 is twice full size.

Referring to the parts by letter, A represents the bed plate of the machine. At one end of this bed plate is secured a standard at having at its upper end a long sleeve a. The driving shaft a is journaled in this sleeve. At one end of the shaft are the fast and loose pulleys 0. a. upon which the driving belt runs.

13 represents a hollow cylinder having, at or near its longitudinal center,ahub 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 O, 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 b are the heads d, the purpose of which will be hereinafter explained.

Projecting radially outward from each rod is a beveled arm d These arms project from the cylinder in a spiral and each is so placed that it will, as the cylinderis revolved, strike its associated bar a when the same is moved out by the operation of its key.

The cylinder is madeof two separable parts which are connected by means of bolts as shown in Fig.3. The right hand end of the cylinder is that part of the cylinder from which the arms d project, and is permanently fixed in the described relation to the otherparts. The left hand end of the cylinder carries the dies 0, 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 ends 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 con- 'nected therewith are. supported by two brackets a a which are attached to the bed plate. A cylindrical rod eis secured to said brackets and extends through theleft bracket (1. Between the brackets, the keys E areloosely hung on the rod e, being separated by washers.

e represents a round rod which is fastened at its ends to the brackets a a. On it are mounted the bell crank levers 6 One arm of each of these levers is connected with a sliding bar 6 which is supported in and guided by the cross pieces 6 This cross piece is connected at its ends with the brackets 01. a. The other arm of the bell crank lever is connected by means of a link e with one of the keys. The springs a, each connected with a key and with a rod e exert their force to return the parts to their normal positions as shown in Fig. 7. An angle lever 6 is mounted loosely on the rod 8 just to the left of the bracket 0. A bar c which lies against the upper side of the keys is rigidly connected at one end to the upper arm of the lever e 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 (1 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 (L a is a locking bar e to one end of which a rigid- ICO IIO

E on the under side ofall of the key levers.

Each of these bosses is notched horizontally as shown in Fig. 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 6 is, by means of the connecting mechanism described, thrust outward into the path of the beveled 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 I vent the operation of the machine, unless the thereby rocked and its lower end forced intoone of the notches j,'if the bar J is in the right position to permit this movement. If it is not, andthe 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 e 3. This-is a safe-guard to preguide for the'dies O is insuch 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 a abuts against the. end of the slot in the. linke and the locking bar 6 is thereby prevented from so rocking as to throw the flanges toward the key bosses E; but when the bent lever a has been moved, as before explained,'the arm a ispermitted to move and is moved by the action of the spring J The flange e on the locking bar enters the notch in the depressed keyand 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 (2 which is rigidly attached to the looking bar, and a link e which connects one arm of the'bell lever L with said arm 6 The bell crank-lever Lis rocked after an impression has been made by the movement of a bar I, thereby causing the lockingbar e to be moved back with the result of disen: gaging the flange e from the key bosses and returning said locking bar to its first position. The spring J 'will nowdraw upon'the lever J which in moving to its first position likewise moves the bent lever 6 and the bar 6 attached thereto back to their normal positions.

A sliding carriage H (shown separately in Figs. 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'backward and forward in the mannerandforthepurposesetforth. Around the hub G of the frame, a coiled spring G is placed, and the ends of this spring are connected respectively with said hub and with the standard h. When the frame ismoving 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 9 which lies beneath and more or less nearly parallel to the face of the cylinder,.and an arm g 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 connectionconsists of the following combination and arrangement of parts: Fixed to the bed of the frame is a bracket 9 A rock shaft g is 'journaled in this bracket and in thearm g of the frame.- Rigidly connected with this shaft are two arms 9 and two rods g g are'connec'ted at their ends to said arms,and pass through slots in the arm g and bracket 9 as shown in Figs. 6 and 14. Loosely pivoted on the rod 9 is a plate 9 which lies close to the end of the cylinderB andisheld in the proper relation thereto by a pin 9 which projects into the cylinder and bearsagainst its inner wall, and two flanges g g which engage with the sides of the peripheral end flange b of the cylinder. The plate has a shoulder 9 against which one of the rodsDstrike-s when it has been moved out by the described action of its associated key. To prevent recoil, a latch g is provided which is also looselypivoted-on the rod g and is held inoperative relation with the plate 9 by the head of a screw which passes through a slot in said plate and screws into the latch. The upper end of the ated arm h? 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 swingingframe. Secured to the rock shaft g is-a toe g which-is adapted to push the spring arm h from beneath the-h1g9? when the rock-shaftis rocked. A 7

spring 9 secured at oneend to the bed g, is curved under the rod g and serves to hold the rock shaft, and parts connected thereto, in the position shown in Fig. 14t that is to say,-it lifts the rod g to the top of the slots inthe arm g',the arm g g to which .the rod g isattached, and the rock shaft 9 to which said arms are attached, being moved'in consequence thereof. Tlhe 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 endof the plate'curves away from the cylinder, so that if one of the rods has by accidentbeen moved out from any other point'exceptthat 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 g on the plate 9 and it is latched by the latch g. The first effect of this engagement is to rock the rock shaft 9 and this causes the toe g to push back the spring arm 77. 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 pro jecting 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 beveled arm a fixed to the sleeve a engages behind the head d 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 a swinging frame may not be unduly strained by the pressure of the die upon the matrix, a friction roller h is journaled to the carriage H directly beneath the opening in the matrix holder when the die is making the impression, and a flange g ,on the under side of the bed of the swinging frame, rides upon the roller. Mounted on guides g 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 r *r' which are pivoted to said plunger. Passing through the transverse slots is a bar r secured rigidly to the swinging frame having beveledupper and lower edges. On the face of a bracket 77. secured to the head is the cam groove h, into which a pin 0* secured to the plunger projects. When the swinging frame is stationary,this pin lies at the extreme right hand end of the groove, and below the spring actuated switch W; and the bar r lies be tween two lugs Won the fingersr below their pivots, whereby said fingers are held apart at their lower or grasping ends. When the swinging frame begins its movement, the pin 7' travels in the downwardly inclined part of the groove h 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 'r move off of the bar 1", and the upper lugs r engage with the upper beveled edge of said bar, and thereby the fingers are made to rock upon their pivots and grasp the said die just below its head 0 on its in ner end. The further downward movementof the plunger moves the die outward to make its impression in the matrix. Thefurther movement of the swinging frame causes the pin r to enter and move'in the upwardly inclined part of the cam groove h, 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 olf ofthe bar r and the lower lugs r 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 0 is in the extreme left hand end of the cam groove. A spring actuated pin r with beveled or rounded point enters a slight depression'r in the plunger, and prevents it from dropping by its own weight, and thus, when the swinging frame moves backward, the pin r travels in the upper part of said groove passing over a spring switch h to the position first described. The spring switch, 71 is a pin which passes through the bracket h and projects into the upper part of the groove h, and is pressed forward by a spring, as shown clearly in Fig. 27. The end of the pin which lies in the groove, is beveled on that side from which the pin r approaches it, whereby it is pushed back out of the way of'said pin r When the pin 1" has passed the switch, the switch springs forward and prevents the backward movement of said pin T in the upper part of the groove h", thus compelling said pin 0, when it moves, to move in the descending part of the cam-groove h, as first explained.

Below the bed plate A, a sliding bar I is supported in brackets of a, through which it may be caused to slide in the following manner: A coil spring *5 surrounds the bar and lies between the enlarged end i and the bracket a 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 t" which, as the bar is moved forward,'strikes a pin 1 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 J immediately flies back to its normal position. An arm t lS rigidly secured to the 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 bufier to check the backward movement of the frame.

The manner of securing the dies in the cylinder is substantially the same as is described in my prior patent, No.475,804:,that is to say,- 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 -of the swinging frame. two'sides t t betweenwhich the matrix slides,

ber bushings surrounding them.

The matrix holder T is secured to the bed a bottom 29* and a top plate i 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 truecoursei The matrix indicated by S, and showninZ Fig. 31, is. of any suitable height, although I have found it convenient to make them type high, and a triflelonger and thicker than the linotype to be cast therefrom.

U represents an inclined matrix hopper, which is secured to the carriage H, in which are placed a number of the matrix blocks with a weight against the bottom of the hopper. When the swinging frame is stationary,- the entrance between the plates it of the.

matrix holder is directly in line with the bottom of the hopper. On the carriage are guides upon which a slide 11, moves; and to this slide an arm-u is attached and so placed tha't'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, therebypu'shing out of the holder the matrix in which theim'pressions havejust been made. A lever 14 pivoted to the carriage,'engageswith the slide and affords means formoving 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 the die, plus the normal space between two successive letters by substantially'the same construction and arrangement of parts shown and described'in my prior patent numbered 475,804. In this manner the impressions are automatically spaced according to the varying widths of thevarious letters and characters employed. 1 will now describe" the construction and arrangement of parts for properly feeding the matrix block. '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 sideof their dies. Therefore, when the dies are 'in thecylinder, the rear or right hand ends of all the characters lie'in the same vertical 'plane. On the forward side of each typedie, and integral preferably therewith, is a projecting boss which, when the die descends, strikes the inclined face of a slide it, which is mounted on the matrix holder. These projecting bosses c 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;

It is provided with grooves h.

on its end.

connected with the slide, so that it moves in unison with the slide, as will be apparent from subsequent description. This movementof the matrix block takes place immediately be fore 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 t returns the slide to its first position.

I will now describe the devices by means of which the matrix block is grasped and compelled to move with the slide t Upon a concave surface of the carriage are cam Inaguide on the swinging frame is a sliding bar 9 having a downwardly turned pin which enters said grooves. These parts are shown clearly in Fig. 19 Secured to an arm which is attached to the slide 25 'is a spring plate 25' having prongs i 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 t on the pressure piece is a bell crank levert and one arm of this lever is connected by the link 25 to the sliding bar 9 On the other arm of the lever a friction roller t 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 tostrike into saidblock. If the slide be moved when the parts arein this position, the" matrix will of necessity move in unison with it. When the lever is rocked in the op'positejdirection the spring plate 15 automatically withdraws its prongs from the matrix block. The pressure piece 19 is fastenedtoone' end of a stiffpiece of spring metal, which is fastened atits other end to, one of the sides of the matrix holder. Said pressure piece has a roughened surface at t 'which is adapted tostrike against the side of the matrix block; and an overhanging finger 25 which rests on the edge of the top face of the matrix block. A bracket having an inclinedsurface is secured to the matrix holder and'lies just above and incontact with an'inclined surface on one arm of the lever i 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 h on the carriage, and neither the pressure piece 15 nor the spring plate is pressing upon the matrix block, but when the pin 9 reaches the incline at if, the bar g is moved, the lever If is rocked, and the prongs on the spring plate t are forced, as above explained, into the matrix block. At this instant, the boss c?on the die begins to move the slide F. The feed movement of the slide has been completed before the pin 9 strikes the incline at it which moves the lo'arg in the oppositedirectlon, thereby rocking the lever and permitting the retraction of the spring plate F. It also causes an incline on the lower arm of said lever i to strike an inclined surface on the bracket whereby the pressure piece t 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 madeits impression in the matrix and the frame swings backward bringing the pin g against the incline h, which causes the pressure to be released. The matrix holding, feeding and clamping mechanism is clearly shown in Figs. 19, 20, 21, 22, 23, and 24. I prefer to place the dies bearing the lower case letters and some other charactersin one row on the type wheel; those bearing the capitals, &c., in another row; those bearing the lower case italics in a third row; and those bearing the capital italics in a fourth row. Thenby makingthe cylinder andthe swinging frame relatively movable, any one of these se ries 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 partsof 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 0 adapted to engage with the notches in the plate 0, 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 plungerR and guide 25 of the matrix holder. As a safeguardto prevent injury of the parts by reason of any failure to properly lock the carriage, I secure to the carriage a bar J having four notches j each adapted to certain positions of the carriage to receive the lower end of the lever J whenever a key is struck. If the carriage is not in one of the four correct and operative positions, the lever cannot enter one of the notches j 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 9 and latch g slide freely on the rod g always preserving the same relation with the cylinder without affecting their operative con- The machine is also provided with a typewriter attachment which I will now proceed to explain, wherebya 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 bracketsV V are secured to the swinging matrix carrying frame; and to these brackets are rigidly fastened the four horizontal bars V V and V 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 m are rigidly fixed, and to the upper ends of said side pieces a horizontal bar on is fixed. A frame M consisting of the side pieces m m and a connecting cross bar m is pivoted by pivots at m m to the side pieces m m, 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 V m m The upper part of this frame is pivoted to the lower part by pivots in line with the pivots m m whereby it may swing toward the cylinder in unison with the frame M. To the upper ends of the side bars a n of the laterally movable frame N are mounted the platen roll n and the rolls a 11 01 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 f min the type when the cylinder is moving independently of the swinging matrix carrying frame. A spring P produces this backward movement which is only sufiicient for the intended purpose. On one side of the vibrating frame M is an arm m to which one end of a spring in is connected. The other end of the spring is connected with the side piece m 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 m 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 m and swings the frame M toward the cylinder. In this movement, the frame strikes the arm P bearing the funnel shaped guide P, forces it over one of the type which is then impressed upon the paper. \Vhen the swinging matrix carrying frame .has been connected with the cylinder, as heretofore explained, and is therefore moving in fixed relation thereto, this type writer attachment being supported by said swinging frame is moving in unison with it. A bent arm h is secured to the standard It, and in each-forward movement of the swinging frame, the lever W strikes this arm thereby causing the I spring W returns the lever to a position 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 Fig. 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 71, without any effect on the other mechanism. A

where in the next movement of the frame the same action is repeated. Immediately after the lever W passes the arm h", during the forward movement of the matrix carry,- ing frame, the spring m swings out pivoted frame M and N so that the operator can see whether the correct letter has been printed on thepaper. To the upper end of the paper carrying frame are journaled the platen roll n and a roll 72. for holding the copy, and two rolls of n which serve to hold the two pieces of paper on said rolls. Two inking ribbon rolls n n are carried by the arm P, and the ribbon 11 passes between the funnel shaped guide and the platen roll.

The paper carrying frame is connected with the matrix by mechanism which I will now de-.

scribe, whereby the frame is fed along equally and simultaneously with the matrix. Fastened to the laterally moving paper carrying frame'is an arm N which passes between the two bars V 'V 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 72 and n between which a pin Y projects. This pin is attached to a slide Y which is suitably guided in a path parallel to that traveled by the matrix. Pivoted. to this slide is a spring actuated arm Y having prongs on its end which project through the side wall of the matrix holder and stick intohand; or by suitable mechanism which may be provided for the purpose. In moving backward the paper carrier draws back the slide Y. In thisbackwardmovement of the slide, a pin Y depending from the spring arm Y 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 Z on said rail, thereby swingin g the arm Y outward and applying tension to the spring which actuates said arm. When the pin is moved off of this incline surface,

the spring causes the arm Y to fly down with such force that the prongs are embedded in the matrix, thus making connection, as before carriage, die actuating mechanism likewise supported on said carriage, and mechanism to move said carriage, whereby the die actuating mechanism and matrix carrier are simultaneously moved into line with the dies in any row, substantially as set forth.
