CARTRIDGE-LOADING MACHINE.

SPECIFICATION forming part of Letters Patent No.336,384, dated February 16, 1686.

Application filed May .8, i885. Serial No. 100,004. (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN L. CHAMBER- LIN, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga, in the State of Ohio, have invented new and useful Improvements in Cartridge Loading Machines, of which the following is a specification.

This invention relates to certain improvements in machinery for filling cartridge-shells, the nature ofsaid improvements being pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a front view. Fig. 2 is a horizontal section in the plane a: m, Fig. 1. Fig. 3 is a similar section in the plane 3 3 Fig. 1. Fig. 4 is a vertical section in the plane z, Fig. 2. Fig. 5 is a horizontal section in the plane m :c', Fig. 4, looking upward. Fig. 6 is a vertical section of the powder or shot discharge in the plane 3 y, Fi 2. Fig. 7 is averticai section in the plane z z, Fig. 6,when the discharge is closed. Fig. 7* is a similar view when the discharge is in position to be opened. Fig. 8 is a horizontal section in the plane xn:, Fig. 6. Fig. 9 is a vertical section in the plane 1 Figs. 2 and 3. Fig. 10 is a transverse section of the crimper in the plane as 1;", Fig. 4. Fig. 11 is atransverse section of the cartridge-shell when erimped in the plane y y, Fig. 4. Fig. 12 is a sectional view of the marking device.

Similar letters indicatecorresponding parts.

In the drawings, the letter A designates a colunm which supports the platform 13, and in which is firmly secured the vertical spindle O.

D is the shell-carrier, which rests upon the platform B and turns loosely upon the spindle O. A step-by-step movement is imparted to the carrier by any mechanism suitable for this purpose-such, for instance, as a dog, a,which extends from the main shaft E, Figs. 1 and 4, and which engages with a series of cavities or ricesscs, b, Fig. 5, in the bottom surface of the carrier. After each forward movement the carrier is locked by a stop-pawl, 0 Figs. 1 and 5, which engages with one of the holes a, and which is thrown out of such hole by a cam, f, Fig. 1, which is mounted on the main shalt, and acts upon a lever, 9, just before the next forward movement of the carrier is to take place. The lever 9 can be depressed by hand so as to release the carrier whenever it is desirable. In the circumference of the carrier are a series of semicircular recesses, h, which correspond in number and position to the number and position of the propelling-cavi' ties b. 1n the example shown in the drawings nine such cavities are shown, so that for each revolution of the main shaft the carrier is turned one-ninth of a whole revolution. Each of the semicircular recesses h in the carrier is provided with a semicircular door, i, which swings on a vertical pivot, j, Figs. 1, 2, and 3, and which is provided with a pin, 1:, Figs. 1 and 3, projecting beneath its bottom edge. The door is normally retained in a closed position by a spiral spring, I, wound round its pivot, (see Fig. 1;) but as the carrier revolves the pin kof each door engages with a stationary mm, m, (see Figs. 1, 2, and 9,) which is firmly fastened to the platform B in close proximity to the tube F, through which the cartridgeshells are fed to the machine. The tube F consists of a stationary section, f which is firmly secured to the platform B, and the lower portion of which is cutaway to such an extent that it permits the doori to pass on its inside. (See Fig. 9.) That portion of the stationary section f which is situated above the carrier D is semi-cylindrical,(see Fig. 3,) and the movable section/ is hinged thereto by a vertical pivot, f, round which is coiled a spring, f, Fig. 1,whieh has a tendency to keep said movable section closed, so that the same together with the stationary section f forms the tube F. A cartridge-shell dropped into this tube rests upon the platform B in a vertical position,and as the carrier D revolves in the direction of the arrow, (shown uearit in Fig. 3,)thedoori, next to the tube F,is gradually opened by the cam m, so that it passes in front of the shell situated in the tube F, and when the pin 7-: of the door has passed the cam m the door closes and forces the shell into the recess h of the carrier. The motion of the carrier is so timed that the carrier remains stationary in the position shown in Fig. 3,the door t of the recess It being partially open. On the next forward movement of the carrier the recess h is moved beyond the tube F, and during this movement the door 1' closes upon the shellin the tube, .and as the motion of the carrier continues, the movable section f of the tube F is forced open against the action of its spring, and the shell is carried to the position indicated by the letter S in Fig.3,and hereinafter designatedasthefirststation. Immediately after the shell has passed out of the tube F the movable section of this tube closes, leaving the tube in the proper condition for the reception of the next shell. The shells may be dropped into the tube F by the person tending the machine, or they may be fed to said tube over a chute, G, such as shown in Figs. 1 and 3. When the chute is used, it is made long enough to receive a large number oi cartridge-shells, and itis provided-with an automatic cut-oft which permits the shells to drop into the tube F successively at the proper intervals. As the shell contained in the tube F is carried out of this tube to the first station, 8, Fig. 3, its rim acts upon a lever, 11, which is firmly mounted upon a vertical spindle, o. The foot of this spindle has its bcaringin a socket formed in the platform B, and it extends up through an arm, H, which. extends from a huh, I, mounted upon the vertical spindle 0. (Sec Figs. 1, 6, and 8.). Round the spindle o is coiled a spring, p, Fig. 1, which has a tendency to throw the lever n, Fig. 3, inward toward the carrier D; and on the upper end of said spindle o is mounted a pinion, q,wbich meshes into asegmental gear, 1', mounted on a vertical tube, a. (See Figs. 6, 7, and S.) The movement of the segmental gearr is limited by a. stop, t, Fig. 8. The tube a has its bearing in the arm H, and it extends from a shell, u, from which rises the cup 2:. which supports the powdercontainer J. The neck of the cup v fits a socket formed in the end of an arm, K,which extends from the huh I, so that when the lever 11 is moved outward by the action of the shell in the first station, 8, Figs. 3 and 8, the powdercontainer is swiveled into the position shown in Figs. 6, 7, 7*, and 8. The object of this movement of the powder-coutuiner is to throw the powder'dlscharge L in gear with the mechanism which serves to open the same at the proper time. This powderdischarge consists of a tube, Z, which fits the shell u,and is provided with a. segmental opening, Z. By turning the tube 1 in the shell u the opening Z can be brought in position to communicate with .the cup 1:, or with the discharge-tube a. In the tube 1 are fitted the' measuring-tubes Z, the heads I of which leave a space, I, which, whenever the opening 2' communicates with the cup v,hecomes charged with powder, and when the tube 1 is turned in the direction of the arrow marked near it in Fig. 7, so that the opening l communicates with the discharge-tube a, the powder contained in the measuring-space.Zfiows out into the shell beneath.

For the purpose olturningthetube 2,whereby the powder-discharge L is opened, I use a bar, M,which is provided with two slots, mm', andwhich is secured to a cross-head, N,whieh is guided on the central spindle,G,and to which a risiug-and-falling motion is imparted from the main shaft E. From the tube I extend three pins, l Z Z, and when the powder-discharge is in the position shown in Figs. 6, 7, and 7* the plate M, on its downward movement, first strikes the pin Pand turns the tube 1, so as to throw the pins 2' l in gear with the slots m m, respectively, and to bring the opening 1 over the discharge-tube s. The slotmis oi such alength that the opening 2 remains over the discharge-tube s a suiiicicnt length of time to allow all the powder contained in the space I to flow down into the shell. 0n the upward movement of the bar M the tube 1 is turned back to its normal position. It will be seen from this description that the powderdischarge L will not be opened ilitis not turned into position to bring the pins 1 I Z in gear with the bar M, and since this movement is produced by the action oi the shell which is to receive the powder. no powder will flow from the discharge unless the shell which is to receive the sameisin the proper position. By placing the operation of opening the powder discharge under the control of the shell to be charged the danger of spilling the powder over the machine du ring the operation of loading the shells is avoided, and the operation of loading the cartridges by means of my machine can be carried on with perfect safety, whereas it the operation of opening the pew der-disch'arge is controlled by means independent of the shell to be charged, and it happens that no shell is in position to receive the powder, when the discharge is opened, such powder will be spilled over the machine, and may be liable to cause an explosion.

The-shot-discharge is constructed precisely like the powder-discharge. The shell 1!, Fig. 7, may be provided with a packing, u, so as to prevent the powder or shot from passing between said sheil and the tube 1 The cartridge-shell, after having been charged with powder, is moved to the second station, S, by the next movement oi the carrier, and as soon as the shell releases the lever n, the spindle 0 follows the action of the spring 1;, and the powder-discharge is returned to its normal position, in which it is not utlected by the bar M. As the shell is being carried from the first to the second station its rim acts upon the lever O, which is mounted upon a vertical spindle, o'. Thisspindle hasits bearings below in a socket in the platform B, and above in an arm, P, which extends from the huh I, Figs; 1 and 3. On the spindle o',near its upper end, is firmly mounted a lever, o, with a curved slot, 0, which engages with a pin, 0, Figs. 3 and 4. This pin projects from a carriage, p, which moves in a radial slot, p, in the arm P, and which carries the wudpusher p. The wad-container Q consists of a series of vertical-rods, or ofa tube, and it is provided with a gate, g, which can be adjusted so that the lowest wad in the wad-container can be pushed out by the pusher 1). As the rim of the shell passes the lever 0 the pusher p is forced inward by the slotted lever o and the lowest wad is carried overthcthimble q,Fig. 4,where it is retained by two spring-jaws, q, Fig. 2. The pusher p is immediately drawn back by the action of the rim of the shell upon the nose 0 of the lever 0, Fig. 3, whereby the spindle of is turned back to its normal position. The shell has now reached station S, rightbcncath the thimble q, Fig. 4, and the wad situated upon said thimble is driven down into the shell by the raunner It. The lbimble q is fitted into a socket in the arm I, and it is supported by a spring, q, Fig. 4, so that when the rammer it strikes the wad upon the thimblc the spring yields and the lhimblc is driven down, so as to embrace the mouth of the eartridge'shell C and prevent the same from being spread by the entrance of the wad. 'lhc rammer R is fitted into a hollow screw-spilt die, 1-, which screws into the cross-head N. In this hollow spindleis placed aspiralspring, 2", which acts upon a shoulder of the manner, and the tension of which can be adjusted by a nut, r", titted upon the upper end of the rammer, which extends through the topof the screw-spindle 1''. On the rannncr are marks indicating the pressure to which the raunner is adjusted. in the example shown in the drawings, Fig. 4, it is adjusted to twenty pounds pressure, and when it drives the wad into the shell the powder contained therein is compressed with a pressure equal to twenty pounds. By turning the screw-spindle 1'' this pressure can he increased or diminished. By the subsequent movements of the carrier D the shell is moved successively to the stations S S, in each of which it receives an additional wad. 'lhcn itis moved to station S, in which it receives the shot, which is introduced into the shell from the shot-container J',precisely in the same manner in which the powder is introduced from the powder-container J. After the shell has been charged with shot it is moved by the carrier to the station S, in which it receives a wad, and then it is moved to station S, in which it is crimped. This operation is effected by means of the crimper T, the torm of which is shown in Figs. 1 and 4. It consists of a thimble which is provided on its inner surface with a series of inwardly-projecting ribs,(see Fig. 10,) which compress the mouth of the shell 0', in the manner indicated in Fig. 11. In the example shown in the drawings, Fig. 4, the cri mper is secured to a rod, t, which passes loosely through an arm, U, extending from the hub, and also through the cross-land N, and which is provided with two stops, t t. In the example shown in the drawings these stops are formed by nuts, so that they can be adjusted toward or from each other. \Vhen the cross-head occupies its highest position, the crimper is sustained by the stop t at a slight distance above the shell, and when the cross-head descends the crimpei' catches over the month of the shell, and by the action of the cross-head upon the stop t" the-crimper is depressed and the mouth of the shell is erimped, as already described. By the next movement of the carrier .D the shell is moved tostationS, where it is exposed to the action of the marker V. This marker consists' of a tubular rod, 1;, which is secured to the cross-head N, and of a die, a, which is inserted into the bottom end of the rod 2). (See Figs. 1 and 2.) On the rod 1) is secured a tray, 1), which swings on ivots v, and which contains the inking-pad A spring, a, re tains the inking-pad in contact with the die. When the cross head descends, the tail end of the tray a strikes a stop, 1;, which extends from the huh I, Fig. 12, and by these means said tray is turned so as to allow the die a" to act upon the wad contained in the top of the shell. The rod 1: is made telescopic, and the lower port-ion thereof is exposed to the action of a spring, so that the die acts upon the wad with a yielding pressure. After the wad in the top of the shell has been marked the carrier l) is moved forward so as to move the shell to station S. Atthis station thedoor 1', which retains the shell in the cavity h of the carrier, is opened by the cam nand the loaded cartridge drops down through an opening, d, in the platform B, Figs. 2 aml 3, into a chute or hopper, which comluets the same into a suitable receptacle. The movements of the carrier D take place when the cross-head N has reached its highest position.

In the platform B are a series of openings, d, one at each of the stations S S S, Figs. 2, 3, uml 4, and these holes are normally closed by the ring-plate d, which contains a series of holes, d", and which is fitted into a recess in the platform. In the normal position of the ring-plate theholes d arcintermediatc between the stations; but it this ring-plate is turned by means of the handle d, Fig. 3,50 as to carry the holes doverthe holes (2" in the platform, any of the shells may be dropped down by opening the door 1', which retains the same in the carrier. The hub I fits the central spindle, C, loosely, Fig. 4, and it is supported by a pin, a, which extends through a rod,c,nnd two slots, c,iu the central spindle,G, the upper portion of said spindle being bored out to receive the rod 0. The upper end of this rod is provided with a screw-thread which engages with a tubular nut, c. This nut is fitted into the upper end of the spindle C, and it is provided withahcad, 0, by meausofwhich itis turned. Ihe object oi this arrangement is to provide means for adjusting the various devices supported by the arms which extend from the hub I, and to bring said devices in the proper relation to the shells to be loaded, since my machine can be used for loading shells of different lengths.

X is an alarm, which is in position to be actuated by the ram mer B, Fig. 4, which drives a wad into the shell. On the manner is secured a collar, r, and if the shell has not been correctly charged, so that the rammer enters the shell to a depth beyond the point which it would reach it the shell had been correctly charged, the collar 1* strikes the leverr and the alarm is sounded. The shell is then removed t'rom the carrier in the manner a ready described before it is exposed to the action of the crimper and the marker. and after its contents have been removed it can again be fed into the machine to receive a correct charge. The collar 1- is adjustable on the ramtner.
