CASTING-CONTROL MECHANISM FOR LINOTYIQE-MACHINES.

. mg at Woonsocket, in the county of Providence and State of Rhode Island, have invented a certain newand useful Improvement in Casting-Control Mechanism for Linotype-Machines, of which the following is afull, clear, and exact description.

In the kind of linotype machines to which the present invention is adapted, independent matrices and spacers are assembled in a line on what is commonly called an assembling rail. Then a device, generally referred to as a line carrier, pushes this line of matrices (and spacers) along to a definite position, where the line will come under the influence of other mechanism by which they are accurately placed and clamped in front of the mold. The clamped matrix line is then caused to close one side of the mold slot, and then molten type metal is injected into the mold slot for the purpose of making a linotypex After this the matrices are removed and automatically carried to the embrace of the matrix distributing mechanism. When everything works right, these various'operations are carried on automatically and in pro-per sequence. If, however, the line carrier were to fail to carry the matrix line to the required osition to be engaged and operated upon y the mechanism provided for that purpose, and if nevertheless the clamping mechanism, the casting mechanism and elevator mechanism were to operate in the ordinary way, the results would be a serious damage to the malinecarrier has chine.

The.present invention is particularly intended as a safe guard to prevent the operation of the said mechanisms, unless the moved the line to the proper I position.

i The invention in the precise embodiment shown is especially contrived for use in connection with substantially such a linot-ypc making machine as is shown either wholly or in part in various patents granted to the Electric compositor Company as the assignee of different inventors.

Patent No. 921,063, particularly in Figure 19, shows some of the mechanism which the present invention, in the particular embodiment shown in the drawing, is intended to allow to operate or to prevent operating, as circumstances require. The invention, however, is not necessarily restricted to an embodiment especially adapted for this machine.

In the drawings, Fig. 1 is a front elevation of the mechanism which constitutes the preferred embodiment vention and some associated parts,-a part of a frame member being broken away, and

of the present inother parts of the frame, and two shafts be- Fig. 2 is a sectional end said mechanism,-the section being of Fig. 1, when the line carrier is at the end of that movement by which it carries a matrix line to the casting mechanism. Fig. 3 is a front view of some of the parts shown in Fig. 1, showing their relative positions when the cam shaft has heenreleased. Fig. 4 is a sectional side view of the parts as shown in Fig. 3; and Fig. 5 is a view similar to Fig. 3, except that it shows the position of the parts when the operator has intentionally thrown them into such position that the camshaft will not be released.

Referring to the parts by reference numbers, 245 represents what is commonly known as the recorder shaft; and 4 represents what is known as the casting mechanism cam shaft. Both of 'theseshafts are normally idle, but, at the will of the operator, the shaft 245 may be caused to make one complete revolution.

45 represents a ratchet wheel which is rotatably mounted upon the shaft 4 and is to be constantly rotated by any suitable mechanism. Fixed to the cam shaft is a disk 17 carrying a pawl 46 which is fixed to a rock shaft 47 mounted on this disk. This rock shaft is under the influence of a spring 49 tending to carry the pawl into engagement with said ratchet. A trip arm 48 is fixed to the rock shaft 47 in such position that as the disk 17' rotates it may strike the end of trip lever 36, wherefore the pawl STATEQEXIENT OFFICE.

5 cam shaft "4 is onewhichcarries various cams for operating the casting mechanism,

and the -mechanisms by which the matrix line is moved from place. to place and utilized for the making of a, linotype. It is to be understood that the recorder shaft, at a suitable part of its revolution will trip the release lever36, and allow the pawl 46 to "fly into, engagement with. the ratchet 45,

whereupon'thecam shaft 4 rotates and the v the movement of the assembled matrix line, will operate in proper s afl nce.v I he parts above described are substantiallylike thecorresponding parts shown and described in Bellowss Patent It will be understood by those familiar with this patent that this shaft 4 carries numerous cams which control the operafor clamping the line, for causing the matrix of the mold, for ejecting molten metal into the mold, for ejecting the linotype, etc'.; and that therefore, unless the shaft'4 turns,

the matrix line will remain in the position to WhlCh the line carrle flhas moved it; and

that none of the mechanisms, which include the. line clamping mechanism, the castmg mechanism, etc., will be operated. 'It

ject of the invention shown, is to prevent, e ther at will or automatically, as when the line carrier has not properly done its work,

theoperative connection of the said shaft 4' g direction and moves right, to the-posit on The assembling-rail, on which the line of matrices are assembled, has 1 through it. The. line carrier slide: 246 moves in guides on, a frame member beneath this slotted rail, and has a thin arm 240-p1voted to its front endand extending upward andto the left therefrom through the slot 1; said arm being; under the influence of a yielding spring plunger 251 to hold it up intheposit-ion to, engage with the rear end of a matrix line, This slide 246 is connectedas shown in said prior patent with opposite ends of'la belt250 which is driven by the driving pulley 261'. This isfixed to the upper end of the vertical shaft 262. The vertical shaft 262 is turned first in one direction and then in the I other, or is allowed to stand idle, through the operation of a clutch sleeve 268 having The shaft 262 has a bevel gear 265 secured to its lower end; and this gear meshes with two beveled gears 269 and 270 which loosely embrace a shaft i 271. This shaft is constantly driven by any pivoted to a fixture, 275 which engages with the side faced cm 276 fixed to the recorder shaft 245, This recorder shaft, in' a linotype machine in do with the casting;

suitable mechanism, as, for example, a sprocket wheel 279 fixed to it, and adriven sprocket chain 284. These two bevel gears 269 and 270 are provided with clutch-jaws facing the clutch jaws onthe clutch sleeve 268. This sleeve is splined to the shaft 271 and therefore rotates with it; but it has an annular groove 268 with which a forked lever 275 engages. This fork lever 275 is and it carries a roller which this invention may be employed will preferably be set in operation at will, as

by the depression of the line key, and it will make one complete revolution and then stop but it is a natter is driven by hand or'by mechanism, orhow it isset in operation-and stopped when it has completed its revolution-.

In the u per end of this lever is a spring pawl 62. ixed to the line carrier slide 246 1s a dog 249 having a This dog is so placed, relativeto "the upper end of the lever 60 and the, spring plunger 62 therein, that,;when the line carrier moves to the left, the beveled .face of the dog 249 will engage with the When the shaft 262 is beingrotated; by the I ear 269, said shaft turns in thecontrar'y sleeve 268 should be in the neutral position. I will now describe the mechanism through 60 is fixed to arock plunger 62 and will pressit down so that the dog 249 may pass carrier moves as far as 1t should to properly place the matrix line, the dog will pass entirely over the spring plunger, and the latover it. If the .line a ter will fly up behind the dog. If the movement of the line carrier is checked in any manner before it moves as far as it should, said dog will not pass this spring plunger, and therefore, as will be seen, the .lever will not be operated when the line carrier moves to the right. Assuming, however,

that this dog has passed the spring plunger 62, then when the line carrier moves to the right, the dog, by pressing against this spring plunger will rock lever 60 and swing it until the dog can slide over the spring plunger 62.

Fixed to the rock shaft 61 is a bell crank lever 64. The horizontal arm of this lever lies beneath an arm on a bell crank lever 65 which is mounted on a fixed screw stud 65". The vertical arm of the bell crank lever 64 engages with a stop pin 66 to limit its movement in one direction, namely, the direction in which shaft 61 is turned by the action of sprin 66. The stop 66 is carried by a fixed portion of the frame ofthe machine. The vertical depending arm of the bell crank 65 is forked as at 65; and the castin controlling fork 67 is pivoted to said depending arm of the bell crank 65, on a pivot which is at right angles to the pivot on which said bell crank turns. The vertically slotted lower end of the fork 67 engages in an annular groove in a pin 35. This pin is horizontalliy movable inv a triangular frame 34, which rame is slotted vertically so as to permit the fork 67 to pass to the position where it may engage said pin. In its normal position this pin is inoperative, but when moved by the line carrier, through the train of mechanism described, this pin is pushed,

forward and over the end of anyarm 36 of the lever 36 which is'loosely hung on the stud 261, as shown in Fig. 4.

The frame 34 is pivoted to one arm of the lever 33, which is loosely hung on the fixed stud 261. This lever carries a roller 33 which engages a cam 32 fixed to the recorder shaft, and itis held in engagement with said cam by a spring 33*. The frame 34 also embraces the fiat slotted head 72 attached to the endwise movable rejector rod 71; and a pin 34' carried by this frame 34 goes through the vertical slot 72 in said head. When this pin 35 has been moved so as to project over the end of arm 36, the recorder shaft 245 may be turned. The cam 32 thereon will rock lever 33; said lever will draw the frame 34 down; and the pin 35 by engaging with the arm 36*, will'swing the lever 36 so as to withdraw it from engagement with trip arm 48, as shown in Fig. 3, whereupon the spring 49 will swing gagement with a ratchet 45, and then the cam shaft 4 will be turned. There is a spring-actuated retaining pawl 68 mounted upon the same pin 34 which connects frame 34 with lever 33. Normally this is spring pawl 46 into enend of the fork 67, which permits said fork,

under the influence of the spring 66", to back to its normal position. As shown in Fig. 3, a shoulder 68 on the pawl 68 engaging a part of the lever 33 limits the spring induced movement of said pawl. Figs; 3- and 4 show the position of the pawl 68 relative to the fork 67 when the lever 33 has been rocked by the cam 32 for the withdrawing the lever 36 from its engagepurpose of ment with the arm 48. When the described parts have performed their function as de* scribed, and the lever 33 is allowed to be drawn by its spring 33 back to its normal position, the spring'66 will immediately swing the bell crank 65 and with it the fork 67 and pin 35 back to their normal positions, and then as the frame 34 is being lifted, the top of the pawl 68 will en a e with the lower end of the fork 67 and %e returned to its initial position, as shown in Fig. 1. i

It will be understood that if the line carrier does not move as far as it should toward the left, the lever 60 will not be rocked, and therefore none of the parts controlled thereby will be moved. When, therefore, cam 32 rocked lever 33 during the revolution of the recorder shaft 245, it willdraw the frame 34 down, but the pin 35, not hav-- ing been projected out over the arm 36, will not move the latter, and therefore the shaft 4 will not be connected with the ratchet 45.

It sometimes happens that the operator. may wish to reject a line of matrices-that is to say, may not wish to cast a line of type therefrom. In that event he may press down upon the vertically movable spring actuated key 76. The lower end of this engages the horizontal arm of a bell crank lever 84, the vertical arm of which has a slot and in engagement with the rejector rod 71. his will cause the movement to the right of this rod, and this will carry the upper end of the frame 34 to the right far enough to carry the pin 35 to the right of the arm 36. Now, although the lever 60 is rocked by the line carrier, and the pin 35 is projected, it will not strike arm 36 when the frame 34 'is' drawn down; and therefore the lever 36 will not be drawn to the pawl-releasing position. Fig. 5 shows the position of the parts when the operator has by the depressing of the key 76 at them into inoperative position described Having described my invention, I claim: 1.
