CARTRIDGE-LOADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,964, dated November 12, 1889. Application tiled December 8, 1888. Serial No. 293,009. (No model.)

To all whom iv' may concern.-

l'e it known that I, ULRICH BACHMANN, of St. llelcna, Napa county, State of California, have invented an Improvement in Cartridge- Loading Machines; and I hereby declare the 'following to be a full, clear, and exact description of the same.

My invention relates to the class of cartridge-loading' machines; and my invention consists, essentially, in a rotary shell-table provided with circular concentric series of holes or sockets for receiving; the shells, said table being mounted in a frame and adapted to slide diametrically, whereby any of its concentric rows of holes or sockets and any hole or socket of cach row may be brought into position.

My invention further consists in the construction and arrangement of the feeding,` devices for supplying the shells and the novel punch, cap-presser, and rammer for decapping and reeapping the shells and forcing the bullets home, all of which l shall hereinafter 'fully describe by reference to the accompanying drawings, in Which- Figure l. is a side elevation of my machine. Fig. L is a view of the bullet-rammel'. Fig. 3 is a vertical central section of the parts below and an end viewof the parts above. Figa/t is a section showing the means for varying1 the` length. of the powder-charging tube. Fig. 5 is a plan of the machine, a portion. of the platform a being broken away.

The object of my invention is to provide a simple and effective machine of this class which can be operated rapidly and with precislon.

A is t-he main frame of the machine, oonsisting` of a bed a, above which is supported a platform c.

B is the shell-table, consisting of a disk havin bored. through it circular rows or series of holes l), said. rows being,` concentric, as shown, Fig. 5.4 This table rests upon a baseplate or disk C, having,` grooves or holes c, and is held thereto by short doWel-pins c', passing into sockets in` the table, so that the said table may be removed from the base-plate andreversed, as will be more fully described,Fig.

l) is a slide-bar, which is provided at its center with a vertical pivot-pin @which passes .freely through central holesin the base-plate C and shell-table l, whereby both said plate and table may be rotated about said pin as a center. The slide-bar is fitted in agroove a2 inthe bed a. of the in ain frame, said groove bein g located in the diametrieal line of the bedplatc, Fig. 5, whereby when moved forward or backward the shell-table is moved diametrically.

On one side of the raised platform a is the standard E, in which is mounted a verticallymovable rod or punch F, which passes down through the edge of the platform and has on its lower end a pin f. A spring,` f encircles the upper portion of the punch and Serves to hold it n p normally. The top of said punch is provided with ahead-picocfz, Figs. l. and 5. livoted in the top of the standard is the lever or handle G, the body or stem g of which is adapted to come in contact, when forced down, with the head of the punch, whereby said punch is forced downwardly. This punch is for Athe purpose of decapping the empty shells, as will'be more fully explained hereinafter, Fig. 5. 1

Secured to the edge of the raised platform a is the standard Il, in which is mounted and adapted to move up and down a rammer 7L, the upper end of which is provided or `formed with or `formed into a rack h', with which a pinion h2 engages, said pinion being on a shaft which is operated by the lever I, Figs. 1, 2, and 5. Around the lower end of the rammer is loosely fitted a sleeve J, between c'ff'i the head of which and a shoulder 7b3 on the rammer above is a spring j, tending to hold said sleeve down against a fixed pin j in the.4 rammel', on which the sleeve is slotted and hung up on the rammer, said pin limiting the downward movement of the sleeve, FiO. 2.; I

The side of the sleeve at jg is open and the lower end or foot of the sleeve is annular, and into Vthis is itted a cap-presser K, consisting of a short metal bar or piece, Fig. 1.' The mechanism thus described has a double f u nctionnviz. ,th at of recapping the shells and' of pressing or ramining home the bullet-and its operation is as follows;

As a recapper, 1, the lever or handle is turned'baelmvard to its'liinit, thereby raising the rammer, and with it the sleeve and its cap-presser, as said sleeve is hung,` froml the rammer on the iixed pin j. Now, when the IOO lever or handle is relieved, the parts move down slightly, so that the cap-presser K. rests on top of the cap. Now, by moving the lever forward, the rammel' itself moves downward, while the sleeve and its cap-presser remain stationary, being held by the shell on which the cap-presser bears below. This downward movement of the lever condenses the spring, and finally the lower end of the io rannner comes in contact with the upper end ot' the cap-presser with a gradual or gentle force, the shock being taken offby the condensing spring, and thereupon said raminer forces the cap-presser downwardly, so as to i 5 put the cap on the shell.

As a bullet-rammer the operation is as follows, Fig. Q: lhe eappresser 'l is removed from the lower end of the sleeve, andthe lammer and sleeve move upwardly above the 2o end of the cartridge by throwing 'back the handle or lever. Now, when thehandle. or lever is thrown forward again, the annular foot of the sleeve comes down upon the rim or mouth of the shell and encircles the bullet, 2 5 which is tit-ted to it through its open side j? The further movement of t-lie lever forces the raminer upon the top of the bullet, thereby pressing itho111c,ai1d this force is not a sudden one, on account of the condensing of the 3o spring. The lower end of the rammer is properly grooved out so as 'to iitthe end of the bullet; but in order to prevent the rammer from being forced down too far I have a set-screw L let through the end of the handle or lever, said screw being adapted to bear against the body 0f the bracket and limit the stroke of the lever, this limit being made variable by moving the screw, Fig. l.

In the other edge of the raised platform civ 4o is the feed or charging tube M, below which is the feed-funnel N, Figs. 3, 4, and 5. The upper portion lof this feed-tube is controlled' by the slide-valve O, and its lower portion is controlled bythe slide-valve P. lThe upper valve O is secured to a stem 0,-h-avinga cross-head o,with springs o2 attached, said springs 'serving to hold the valve normally open, Figs. 3 and 5. Under the platformis mounted a rockshaft Q, having on one end the hand-wheel q,

5o by which it is operated. Secured to this shaft and adapted to be wound thereon are cords R, which extend upwardly from the platform and over guide-pulleys r, and are attached to the cross-head o of the valvestenro. The

lower slide-valve P is secured to the end of a stem p, Fig. 5, which is pivoted at the point 2i under the platform, and to this stem is secured the spring p2, which serves to hold the valve normally closed. A cord @Sis attached 6o to the rockeshaft and, also to the stem p of the valve P, and its length is such as to cause .the valve Pto move after the movement of the upper valve O.

U is a hopper for supplying powder to the 6 5 feed or charging tube. This hopper consists of a main-portion and a smaller receptacle or funnel/Ll., Fig. 3. The former has a sloping bottom and communicates through a hole with the latter, which is attached at one side of the bottoni of the main portion, and said. 7o funnel communicates directly with the feed or charging tube. The object of this is to provide for a more regular and positive discharge of powder than it' it passed directly through a hole in the bottoni of the main portion, .for into the funnel but a limited amount can pass, (just enough to cover the communicating aperture,) and it is relieved of undue pressure.

Although I have described the upper end of 8o the feed or charging tube as being con-` trolled by a slide-valve O, it will be seen that said valve is not located in the tube proper, but is in a plate V, Fig. 4, having a hole fu, which practically forms an extension of the S5 tube, and said hole fits down over the top'of the tube. The plate V is nia-de vertically adjustable, so as to lengthen or shorten the tube to vary the charge of powder in the follow'- ing manner: \V are guide-screws passing 9o freely through the plate V and into the vplatform a. Around these are fitted sleeves w, having exterior threads seated in threaded sockets in plate V. v3y turning these sleeves the plate is raised or lowered for the purpose described.

The operation of the valve mechanism is as follows: The upper valve O is normally open and the lower valve I? 'is normally closed. The charge of powder within the feed-tube Ica therefore rests upon the lower valve. Now, by turning the rock-shaft its iirst effect is to wind up the cords R, thereby pulling on the cross-head and stem of the valve O, a11dcausing said valve to traverse the feed-tube, :o5 thereby cutting off the supply of the powder above. As this is done, the slack of the cord p3 being taken up, said cord begins to wind on the shaft and pulls over the pivoted stem of the valve I, whereby said valve .is with- 11o drawn from the feed-tube, and the charge of powder, which is measured by the space between the two valves, is thereby dropped into the feed-funnel N and thence into the shell. The feed-funnelNis mounted upon a springarm n., secured under the platform a', Fig. This arm tends to hold the feed-funnel down normally with its neck in the mouth of the shell. A cord n is attached to said springarm, and, extending upwardly over a guide- 12o pulley n2, is attached to the rock-sliaft Q, and is adapted to be wound upon said shaft at the beginning of its movement, so that the feed-funnel is held in a lifted position when the rock-shaft is first about to be moved. Now,-when said shaft is partially rotated its first effect is to pay out on the cord n', thereby relieving the spring-arin fn, which throws the feed-funnel N downwardly, with its neck' in the mouth of the shell, and the continued 13o movement of the shaft operates the valves, as heretofore described.

In order to provide for a variable charge of powder, I have a sliding valve S", which traverses the feed or charging tube at a point be- I the valve P is held; but as only one of the Valves P or S is to be used at a time I have mounted under the platform near each end the pivoted disengagingstops T, which are adapt-ed to be turned into contact with either ot' the stems of the valves P or S at a" point beyond their pivotal centers, whereby said stems are moved to throw their valves out of operation and to hold them thus, Fig. 5.

rIhe entire operation of the machine is as follows: The empty shells, having the old caps still in tl1en1,are iitted in the holes or sockets of the shell-table, and said table is then placed upon the base-plate C, with the heads of the shells downwardly, there being small holes or grooves c in said base-plate just under the shell holes or sockets of the table. Both table and base-plate being iittedvupon the center pin d of the slide-bar D, said bar is tted in the groove of the bed a of the frame and is moved inwardly, so as to bring a shell of one row directly under the punch F. The handle G above is now operated and the punch is forced down, so that the pin on its lower end drives out the cap from the shell. The punch thereupon moves up under the action of its spring, and the table is then turned axially, so that anotherl shell in the same row is brought under the punch, and so on until all the shells in that row are decapped. Then the whole table is moved diametrically by moving the slide-bar l) so as to bring the shells of another row into alignment with the punch, and when t-his row has been finished the table is again moved diametrically to bring the shells of another row under the punch, and so on until all vthe shells have been decapped. When 'this is completed, the slide-bar D is moved outwardly, so as to free the shelltable', which is then taken off from lthe pin d and reversed and again placed on the pin, so that the heads of the shells are uppermost. The heads of the shells are now provided with caps by hand, and the table -is then putin place again, so as to bring any of its shells directly under the cap-presser K, which is operated,as heretofore described, to force the cap to place, and the table itself is axially rotated and successively moved dia- Ametrically, so as to reach all the shells of all the rows and cap them. When this isdone, the table is again moved outwardly and removed from the pin d and reversed, so as to present the open mouths of the shells upwardly. It is then moved inwardly, so as to bring a shell of any row directly under the feed-funnel N. rlhe powder from the hopper U above is resting upon the lower valve P. Now, the 'hand-wheel q is turned, and immediately the fcedfunnel N, being relieved by the paying out of the cord n', fits'v its neck into the open mouth ot" the shell. Then the upper valve O cuts off the powder above,'and the lower valve P opens the feed-tube, so that the charge of powder drops down vinto the funnel and into the shell. wheel q is turned back again, returning the Then the parts totheir normal position, and the shell- ,I table is turned axially to present another shell to the row. When this row hasbeen charged, the table is moved diametrically to bring another row into place, and so on, as heretofore described.

When the shells have been charged with' powder, the cap-presser K is removed, anda bullet -is fitted through the open side j2 of sleeve J, the lower annular end of said sleeve resting in the beveled top of the hole b of the shell-table and acting as a guide for said bullet. The rammer h is then pressed down and drives the bullet home. provided successively with a bullet.
