ATTACHMENT F/OR CARTRIDGE-PRIMING; MACHINES.

SPECIFICATION forming part of Letters Patent N5. 479,819, dated August 2, 1892.

Application filed March 24, 1892- Be it known that I, JOHN G. LIDDELL, of New Haven, in the county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Attachments for Cartridge-Priming Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the-art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of my attachment; Fig. 2, an end elevation of the same, showing parts of the plunger and cartridgecarrier; Fig. 3, a perspective view of the race detached; and Fig. 4, a like view of the top of the standard, showing race-holder.

Like letters and figures of reference indicate corresponding parts in the dilferent figures of the drawings.

My invention relates especially to an automatically-actuated attachment for delivering caps to the cartfidges in a position to be struck by the plunger; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more efiective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the plungerhead, which carries the ordinary tool E, having a concave Working face and secured in the tool-socket b by a set-screw d in the usual manner.

B represents the ordinary rotary disk, which is provided with spindles 0, arranged in the usual way and upon which the shells D are disposed. These parts being all of the ordinary construction, it is not deemed essential to herein specifically illustrate or describe the same.

A standard G is disposed near the disk B, and at an angle of about forty-five degrees to the line of travel of the plunger a raceway H is mounted. This raceway comprises two curved strips of metal h, (best shown in Figs. 1 and 3,) on each side of which a rectangular Serial No. 426,231. (No model.)

sheet of glass 1' is secured, the glass forming smooth walls for the passage of the caps j, as hereinafter described. The lower glass plate has a steel backing k, and the longitudinal edges of said plates are bound at m. The converging ends of the race-bars h project in parallelism beyond the lower ends of the rectan-' gular plates, forming the race proper p. The steel back is elongated centrallyunder the race proper and thickened to engage the bars 71. and holdthe lower glass plate 1'. A cap-plate t in the plane of the upper glass covers the race proper and is secured by screws 12, passing through the bars it into the thickened portion 60 of the steel back. Between the standard G and the disk 13 a horizontal shaft J is mounted to rotate in standards w, said shaft being slightly out of the plane of the race. The shaft J is provided with conical sockets a: in its ends to receive the cone-shaped ends of screws y, passing through the standards and forming bearings for said shaft. One end of the shaft is screw-threaded at 15. A pinion 16 is mounted looselyon saidshaftbetween tight-fittingwashers17. Jam-nuts18,turnedontosaidshafhre ulatethetensiononthepinion. Averticalrackbar F, secured to the plunger A, meshes with the pinion 16 and reciprocates the shaft J as the plunger moves. A cap carrier K is mounted on the shaft and is constructed as follows: A block 25 is formed integral with or attached in any suitable manner to the shaft, the upper face of said block being so arranged-that it may be thrown into alignment with the bottom of the cap-racep. Pivoted on the block to swing horizontally in relation thereto there are two clamping-fingers 26, the upper ends of which are grooved at 27, forming jaws to receive the caps 3' when discharged from the race, as hereinafter described. The block 25 has a projection 28 on the shaft, the surface of which is in the same plane as the upper face of the fingers 26 and which is disposed below their pivots. To each side of the projection 28 a flat spring 29 is secured, the free ends of said springs bearing, respectively, on the outer edges of the clamping-fingers and tending to force them inwardly toward each other. A stop-plate 30 is interposed between the fingers adjacent their pivots to prevent their free ends comng into contact. A guide-plate 31 is bolted the block across said fingers.

On the top of the standard G there is a vocket 62 to receive the race proper. This is ormed by a plate 61, secured by bolts 0" to he standard. In a suitable chamber or slot F2 in the standard G, at the mouth of the .ocket 62, a cut-off bar 33 is fitted to slide. iaid bar is 'provided with inwardly-projectng arms 34, around which coiled springs We disposed, said springs acting expansively )etween the bar. and the chamber-bottom to ;hrow the cut-off across the mouth of the race groper, which registers with the mouth of the socket when in position.

The races II are detachable from the standtrds and the weight of the body of the race is supported by brace-rdds 50, mounted in any suitable position on the machine-frame. When a race is empty of caps, it can be withirawn from socket 62 and substituted by one filled.

A spreading-screw 36, having a cone-shaped point, is mounted in the standard G adjacent the cut-01f and in such position that it will be projected between the fingers 26 to spread the same for receiving the cap.

In the use of my improvement the ordinary priming mechanism being in motion and the plunger playing vertically as said plunger'descends, the parts being presumed to be in the position shown in Fig. 2, a cap from the race p is between the jaws 27 of the clamping-fingers, and the rack-bar F, driven downward by the plunger, rotates the shaft J from right to left, as viewed in said figure. The tension of the spring 29 on the fingers as soon as said shaft starts and the fingers are out of contact with the spreader 36 causes them to grip the cap,which is carried in the direction indicated by the dotted lines and arrow in Fig. 2 and disposed directly over the cap-socket in the shell D. The parts are so timed that the cap arrives over said socket slightly in advance of the working face of the tool E, which strikes said cap and drives it into the shell in the ordinary manner. A stop 41, comprising a screw vertically adjustable in a standard 42, is disposed in such position that the face of the projection 28 on the shaft will engage it when the cap-carrier has described its arc and disposed the cap in position to be struck by the plunger-tool, as specified. As the carrier is thus stopped, the pinion 16, stilldriven by the rack, slips on the shaft. Sufficient lost motion is thus afforded to enable the plunger to descend far enough to strike the cap. As soon as the fingers of the cap-carriers leave the mouth of the cap-race the springs 35 throw the cut-ofi bar 34 across the mouth of said race, preventing the caps from escaping therefrom. Upon the return of the plunger the shaft is rotated in the opposite direction until the fingers engage the standards G at the mouth of the race, depressing the cut-off. The screw 36 spreads the fingers 26 and admits a cap freed by the cut-off into the jaws 27. The

pinion 16 slips after the clamping-finger meets the standard during the completion of the upward movement of the plunger. The cap being driven into the shell while held between the fingers 26, said fingers contact with the tool E, and their jaws may be slightly beveled to enable them to slip readily over said tool on their return to the race.

Having thus explained my invention, What I claim is- 1. In a cartrid ge-primin g machine, the priming-plunger, in combination with a raceway, a shaft rocked by the movement of said plunger, and spring-tensioned clamping-fingers on said shaft adapted to receive a cap from the raceway, substantially as described.
