SPECIFICATION forming part of Letters Patent No. 642,441, dated January 30, 1900.

Application filed January 12, 1899. Serial No. 701,991 (No model.)

Oastin g and Composing Apparatus, (for which I have made application for patent in Great Britain, No. 15,345, dated July 12, 1898,) of which the following is a specification.

My invention relates to apparatus whereby types are cast in the: order in which they are to be set in a form, the proper matrices for the successive types being brought by means of finger-keys into position facing the type- For this purpose I form the intaglio matrices in rows on the face of an arc of a cylinder which is connected by suitable mechanism to finger-keys in such a manner that it receives a compound motion from these, being turned partly around its axis and moved more or less longitudinally as the keys are depressed, so as to bring the proper matrix of the proper row into position ,this being pressed against the mold while the molten metal is injected. The matrix-arc is then withdrawn from the mold to a position readyto be moved again by depressing the keys. The cast type is ejected from the mold and after certain dressing finds its place in the line of form, compressible spaces being introduced where required and the line being justified by compressing it before passing it into the galley.

The accompanying drawings show mechanism for operating as above set forth.

Figures 1 and 1 together show a plan, Fig. 2 is a longitudinal section of the part of the machine on the right-hand side of the line 2 3 in Figs. 1 and 1, and Fig. 3 is a vertical section of the part on the left-hand side of the line 28. Fig. 4 is an end view partly sectional. Figs. 5 and 5 are vertical transverse sections on the lines 5 5 and 5 5 of Figs. 1 and 1, respectively. The rest of the figures, drawn to an enlarged scale, are: Fig. 6, aplan of the keys with. cover removed; Fig. 7 a vertical section showing the two rows of keys in elevation; Fig. 8, a transverse section showing the interlocking gear of the keys; Fig. 8 a detail plan showing two of the springpressed latches for temporarily holding the keys depressed; Fig. 9, an end view showing the interlocking gear of the keys. Fig. 10 is a detail vertical sectional view showing the matrix-carrier and mold on a larger scale than in Fig. 2. Fig. 11 is a detail vertical sectional view showing, on a larger scale than Fig. 2, the mechanism on which the finger-- keys act. Fig. 12 is an elevation of the matrix-segment and its working gear, and Fig.

'13 shows in detail part of the mechanism for moving the matrixcarrier longitudinally. Figs. 14.- and 15 are elevations looking at the mouth of the mold, showing the gage and cover-slides in the different positions. Fig. 16 is a front View, Fig. 17 a back view, and Fig. 18 a plan, of one of the matrices.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein The letter K indicates the keyboard, having finger-keys arranged into two banks, one at the right and the other at the left-hand side of the longitudinal median line of the machine, and each bank is in two ranks, one in front and the other in rear thereof. The two banks of keys 70 each comprises two keys lo, the left bank comprises a space-key 70 and the right bank a form-key 70 The nine keys is of each bank serve to determine the rocking motion of a sector-shaped matrix-carrier M, hereinafter fully described, and the four finger keys is determine the longitudinal movement of said carrier relatively to the axis or shaft on which it is mounted, as will hereinafter appear. The finger-keys are each urged upward by a suitable spring, as at 1, Figs. 2, 7, 8, and 9, and the stem 15 of each key is provided with a stop-pin 2, working in a vertical slot 3 of a tubular guide 4:, covered by a plate 5, against which the stop-pin strikes to limit the ascent of the key. The heads of all keys, except the keys la, are provided at the lower edges of the front sides with bevels or inclines 6, Figs. 2, 7, 8, and 9, which act upon the upper ends of swing-arms 70 when the keys are depressed, and the lower ends of all the key-heads, except the keys is, are adapted to be engaged by the upper ends of swinging dog-arms 70 when the keys are raised by their springs. The swing-arms k for the front rows'of keys are fixed to rock-shafts 7 7, Fig. 6, the swing-arms for the rear rows of keys are fixed to rock-shafts 8 8, the dogarms for the front rows of keys are fixed to rock-shafts 9 9 and the dog-arms for the rear rows of keys are fixed to rock-shafts 1O 10. These rock-shafts are journaled in suitable bearings, as at 7 7. The rock-shaft 7 connects by a link 12 with the rock-shaft 9 and by a link 13 with the rock-shaft S. The rockshaft '7 connects by a link 14: with the rockshaft 8, the rock-shaft 9 connects by a link 14; wit-h the rock-shaft 10 and the rock-shaft 10 connects by a link lat with the rock-shaft 8 and by a link 14 with the rock-shaft 9. The links connect with short crank-arms on the rock-shafts, though, as shown, some of the links connect at one end with some of the dog-arms k which serve the same purpose. The construction and arrangement are such, as best seen in Fig. 6, that if a key 70 or the space-key k of the right-hand bank is depressed the dog-arms of the keys in the lefthand bank are thrown forward under the heads of the keys k and 70 and none of such keys can be depressed at the same time as the right-hand key. Conversely, when a key 70 or the form-key 76 of the left-hand bank is depressed the dog-arms 7.0 of the keys 7.; and 70 of the right-hand keys are thrown under the heads of the latter and none of the keys 7a or the key 70 in the right-hand bank can be depressed at the same time as the left-hand key, as will hereinafter appear.

When any finger-key k or the key 70 of the right-hand bank is depressed, its bevel or incline 6 acts to move the corresponding swingarm a outward, thereby rocking the shafts 7, 9, and 10, causing the dog-arms k of these shafts to swing forward and engage under the heads of the keys 7c and form-key k of the left-hand bank, and obviously, therefore, none of such keys in the left-hand bank can be depressed at the same time as a key in the right-hand bank.

"When any key or the key 70 of the lefthand bank is depressed, its bevel or incline 6 moves the corresponding swing-arm 70 outward, thus rocking the shafts 7*, 8, 10, and 9, causing the dog-arms 70 of these shafts to swing forward and engage under the heads of the keys 7t and the key 70 of the right-hand bank, so that none of these keys can be depressed at the same time as a key in the righthand bank. The stem 15 of each key it and 7a is provided with a rounded groove 16 to be engaged by a spring-pressed latch or plate 70 Figs. 2, 8, 8, and 9, for holding the key down with a certain amount of pressure. \Vhen the depressed key is raised to normalposition, as will hereinafter appear, suitable springs 17 and 18 turn the rock-shafts back to normal position, thus removing the dogarms from under the heads of the keys and placing the swing-arms against the bevels 6 for a subsequent operation. Under each key is a rod 70, guided to slide horizontally and having on it a stop-collar H, which when the rod is in its extreme right position is held by a springcatch 70 with force enough to prevent it from being shaken out of place. Each rod 76 has an enlarged part and boss 10 through which can slide Vertically a plunger 70 urged upward by a spring, but stopped from rising beyond a certain height by a wire it, which passes through a slot of the boss 70 and extends in a curve upward and outward to support an inclined plate 7e attached to the plunger 70 When any key is depressed, the plunger 70 below it isdepressed and its lower end is presented to. a pusher p, hinged on a reciprocating carriage P, the action of which will presently be described, which as it advances pushes to the left the plunger 70, and with it the rod is", the collar 70 escaping the spring 70 As the inclined plate 70 passes under the stem 15 of the depressed key it forces it'up, the spring 70 yielding enough to let it escape from the groove. When the pusher p retreats, a bar p on the carriage]? draws the collar 70 and rod 70 back to the right until it is stopped by the collar 70 attaining the end of its stroke.

The pushers p are hinged to the carriage P, which is caused to slide to and fro on guiderails 19 by an eccentric p on a continuouslyrotating shaft S, the eccentric-strap being connected to the carriage P by a sliding rod 19 link 19, bell-crank p and link 19. The end of each pusher p is somewhat beveled, and the ends of the rods k" are made with correspondingly beveled notches, so that when a pusher 19 engages with the notch the rod is prevented from rising. Each pusher p is urged upward by a spring 13 against the stop-harp, so that it can yield if a keyover it should be depressed when it is not in its extreme right position.

The matrix-carrier M is in the form of a cylindrical sector, having two checks which are circular sectors fixed on a transverse rocking shaft 112. Through a backward prolongation of the cheeks pass two rods m m on which are mounted rollers, the one rod m extending from M to the one side of the machine, the other rod m extending from M to the other side of the machine, and both rods having their ends attached to the shaft m by links m On each of the nine rods 7c, worked by the right-hand keys, is fixed a head a, which, as its rod 70 is moved by one of the pushers 19, travels under a guide-roller u, and on each of the other nine rods It, worked by theleft-hand keys, is fixed a head d, which travels over a guide-roller d. All the nine heads a are made with slopes on their under sides, differing by equal steps, and in like manner all the nine heads cl are made with stepped slopes on their upper sides, only three of the latter being shown in Fig. 11.

In all cases there are flat parts or dwells beyond the slopes. When any one of the heads a advances to the left, it acts on the rollers mounted on the rod m, depressing that rod, and consequently turning the matrixcarrier M on its axis 912, so that its front IIO are ascends a distance proportional to the depth of the slope of the acting head it, and in like manner when any one of the nine heads (1 advances it acts on the rollers mounted on the rod m raising that rod, and consequently causing the front are of M to descend a distance proportional to the height of the slope of the acting head d, as shown by Fig. 11. Then none of the heads to or d act, the matrix-carrier M is urged to a middle position in one direction byits weight and in the opposite direction by a spring m Fig. 12. It is held in the middle position by a roller m on a leaf-spring m engaging or bearing in a-rounded notch in the periphery of the collar Z Those of the rods which are advanced by the pusher p when the keys is are depressed have also heads 1, Fig. 12, sloped in steps to act on rollers I, mounted on the side of a lever 1 which is urged upward by a spring 19. The lever Z terminates at front in a projecting arc Z which is sloped, as shown in Fig. 13, to act on aroller Z This roller is mounted on a'sleeve Z which can slide'along a rod 1, and has an arm 1 bending over and engaged between collars Z within the cheeks of the matrix-carrier,M. Thus when any one of the heads Z advances it depresses the lever l and the sloping front Z of this lever, acting on the roller, Z moves the sleeve Z ,and with it the matrix-carrier M, along its axis m in opposition to a spring 1", which urges M against the stop-collar Z It will thus be seen that while the sloped heads to and d can move Mstep by step around its axis nine steps each way from its middle position the sloped heads l can move M along its axis four steps against the spring 1".

In the curved front of the matrix-carrier M are loosely fitted to slide a little radially nine matrices, as at 20, Figs. 16, 17, and 18, above the middle of the arc and nine matrices below the middle. Each matrix, as shown in Figs. 16, 17, and 18, has in its front five intaglio characters 21, and at its back six holes 22 bored partly into it.

The matrix has its lower side made in steps to determine the depth of the type-mold for each of its characters, as will presently be described. On each of the matrices are projecting pins which work in slots 24, Fig. 2, in the checks of M and to which are attached retracting-springs m". By the action of the keys, as described,the matrix-carrier can be moved so as to bring any one of the 5 X 18: intaglio characters to a central position facing the mouth of the mold, and, in order to determine that position with certainty, a cam Q is so set on the shaft S that, immediately after the carrier M has completed the movement determined by the keys, it allows a spring g to act on a lever q, so as to advance a sliding rod g, having two conical pins g (best seen in Fig. 18,) projecting from it, and cause it to thrust them into two of the holes at the back of the particnlar matrix presented in the middle position, the matrix being thus pushed forward a little against the mouth of the type-mold and held firmly in correct position while a type is cast, as will be presently described. The pins (1 therefore serve to hold the matrix in correct position. If a single pin were used, the matrix might turn slightly on the pin as an axis.

When the slide q and pins g are caused to retreat by the cam Q acting on the lever q, the matrix is retracted by its spring m and the rods 10 which had moved the matrixcarrier M, being also retracted, the carrier resumes its middle position, ready to be acted on again by the keys.

The melting-pot T is furnished with a pump having plunger 25 and a valve 75, both urged down by springs and raised, the plunger by lever t rod 25 and lever i operatedbya cam i and the valve by lever i rod 25 and lever i operated by a cam t". The cams t and t are so shaped and set that while the plunger 25 is ascending the valve 2" is open, allowing molten metal to enter the pump. Just before the plunger descends the valve descends, closing the inlet; but it can rise, giving outlet to surplus metal when the pressure is sufficient to overcome the spring on the valve-stem. The metal is conducted to the end of the mold by a pipe 25 which is kept hot by gas-flames.

The mold-frame has a mold-cavity closed by end walls. The bottom of this cavity is formed by the top of a slide-piece a, which slides vertically between two cheeks, preferably made hollow for circulation of coolingwater through them, these cheeks forming the sides of the mold. The piece a is linked to a lever 61., urged up by'a spring a and having on it a roller a engaged in a cam-groove a in the cam Q. The inner side of the camgroove a is intended to act on the roller a only when the spring-pressed slide a fails to push the type out of the mold, which sometimes is difficult to do, and moves the slide a, a little downward every revolution,the spring or urging it upward until a projection of on the face of a meets the under side of the projecting matrix, which at that time is prevented from rising by bearing up against a sliding piece a. This piece is guided and engaged with the end of a lever a having'at its other end a roller a pressed against a cam a by a spring a The depth of that part of the matrix against which the projection of bears determines the depth of the mold. Another sliding piece a. is linked to a bell-crank a which is linked to a lever a, urged down by a spring 0!, on a cam on. This cam is so formed and set that when the slide a is up to form the bottom of the mold the slide a is covering the top of the mold, the matrix at the same time covering the face of the mold. When the parts are in this position, the molten metal is pumped into the mold, forming a type. The matrix being then retracted, the slide a is withdrawn, so as to I-Is leave the upper side of the mold open, the slide a ascends, pushing up the cast type, and then the slide a advances, pushing the type onto the top of another vertical slide 17, which is linked to a lever 19', having a roller engaged in a cam-groove b in the cam Q. The slide 12 pushes the type up past a cuttingblade 72 which removes the tang from its base and also pasta latch-spring a which prevents the type from descending when the slide 17 descends. To the right of b there is a column b of compressible spaces, the column having at its bottom a channel I), leading toward b.

If no matrix is presented to the mold, the slide a, when completely raised, obstructs the nozzle of the pot, and consequently the metal cannot pass from the nozzle into the mold, but escapes by valve 15 back into the pot.

When a space is required in a line of type, the operator depresses the key on the extreme right. By this movement communicated through sliding rod-such as 7a, a lever 5 and rod 11 having an inclined slota slide 5 is permitted to be drawn to the left by a spring b and this pushes the foremost of the spaces in the channel 12 to the posit-ion of a type above I), so that by the next ascent of b the space is raised. The columns of type and spaces raised by the ascent of b are transferred to galley F to constitute a form for printing in the following manner:

Any suitable construction of compressible spacer may be employed, and as such are well known I do not considerit necessary to illustrate any specific form.

The line is composed somewhat longer than the desired length, and then by the ascent of the slide 1) the line is compressed to the proper length-that is to say, it is justified.

As each column is formed by the successive ascents of the slide b, raising types and spaces, these are held between the face of a pusher f and a rule f, Fig. 5. WVhen the operator sees that the column is completely filled, he depresses the extreme left-hand key k which, through the medium of a sliding rod, such as one of the sliding rods 7c, communicates move ment to the pivoted lever f Fig. 1. The leverf is connected by a rod f with one arm of a bell-crank lever J, the other arm of which is attached to a rod f connected with the pusherf. The rod f is provided with an inclined slot at f engaging a pin attached to the rule f, so that as the pusher f is advanced by the rod f the rule is retracted or drawn back. The advancing pusher forces the column of type and spacers into the galley F to constitute a form. The pusher f is retracted by a springf The types are held in position by a sliding block f having springs that make frictional contact with the sides of the galley. When the galley F is filled, it can be removed, a fresh galley being substituted.

Having thus particularly described and ascertained the nature of thisinvention and the best means I know for carrying the same into practical effect, I claim- 1. The combination of a type-casting mold, a pivotally-supported sector-shaped matrixcarrier having rows of matrices in its periphery, means for rocking said carrier to place any row of matrices level with the mold, and means for shifting the carrier longitudinally with relation to its axis to present any one of the matrices in a row to the mold, substantially as described.

2. The combination of a type-casting mold, a rocking and longitudinally-movable sectorshaped matrix-carrier having rows of matrices in its periphery, sets of finger-keys, devices operated by one set of fingers forturning the matrix-carrier on its axis to place any row of matrices level with the mold, and devices operated by another set of the finger-keys for shifting the matrix-carrier longitudinally to present any one of the matrices in a row to the mold, substantially as described.

3. The combination with a rocking matrixcarrier movable longitudinally relative to its axis, of depressible finger-keys, means for locking the keys depressed, sliding rods having heads provided with stepped inclines, rods connectedwith the matrix-carrier and acted upon by the stepped inclines when advanced with the sliding rods, spring-plungers mounted on said rods and depressed by the depression of the keys, a carriage having pushers arranged to engage said plungers when depressed, and means for reciprocating said carriage, substantially as described.

4.

5. The combination with the matrix and mold-frame having a mold-cavity, a pair of horizontal slides the one engaging on the upper edge of the matrix, the other sliding over the mold-cavity and a pair of vertical slides, the one meeting the lower edge of the matrix and forming the bottom of the mold-cavity, the other pushing up the cast type to form a column, and the cams and springs for operatin g these slides, substantially as described.

6. The combination with a mold-frame having a mold-cavity, of a horizontal slide to form the top of the mold-cavity, a primary vertical slide the upper end of which forms IIO space-key, whereby the space-pushing slide may move to push the space, substantially as described.
