CARTRIDGE-ELEVATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 515,130, dated February 20, 1894.

Application filed December 1. 1893. Serial No. 492,4:70. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bolt-Guns, of which the followingisa specification.

This invention relates to that class of breech loading tire-arms known as boltro guns, and has special reference to the mechanism for elevating the cartridges in the cartridge-magazine or packet-case.

The object of this invention is to furnish the gun with improved mechanism for elevating [5 or feeding the cartridges, which shall be simple in construction, automatic and effective in its operation, and which shall also form a suitable guard for the trigger of the gun.

In the drawings accompanying and forminga part of this specification, Figure 1, Sheet 1, illustrates in vertical longitudinal section a bolt-gun as provided with my present improvements, the cartridge-magazine being shown as filled with cartridges and the cartridge-lifter in operative engagement therewith. Fig. 2, Sheet 1, is a sectional detail, taken in dotted line bb, Fig. 1, showing the guard block or strap, the cartridge lifter journaled therein, and the cartridge-packet, in their relative positions, as seen from the left-hand in said Fig. 1. Fig. 3, Sheet 1, is a top View of the cartridge-packet, cartridgelifter, guard-block or strap, and trigger, a

portion of the guard-block being in section.

5 Fig. 4:, Sheet 2, is a side view of the guardblock, with its side plate removed. Fig. 5, Sheet 2, is a top view of the guard-block with its side plate attached. Figs. 6, 7 and 8, Sheet 2, are side, top and end views, respectively, of the cartridgelifter. Figs. 9, 10, 11 and 12 are details of difierent members of the cartridge-lifter-actuating device. Figs. 13, 141 and 15 are details of the ball-socket bearing for said actuating device.

5 Similar characters designate like parts in all the figures.

In the drawings, only so much of a boltgun and its connectedmechanisms is shown as is pertinent to a clear understanding of my improvements thereto, and the operation thereof.

My present improvements are adapted to be used in connection with breech-loading firearms of various constructions employing a horizontally-reciprocating bolt and a vertically-disposed cartridge-magazine or case; but the improvements are especially applicable to the particular bolt-gun herein shown, which is or may be substantially similar to the bolt-gun shown and described in United States Letters Patent No. 506,319, granted to J. P. Lee October 10, 1893.

Referring to the drawings in my present applicationz-such details and parts therein shown as correspond with parts shown in the 5 application and patent referred to, are generally designated by like characters. Accordingly, the following parts are or may be the same as the parts designated by the same characters in said application and patent, towit:the receiver or gun-frame, designated by B, adapted for carryinga sliding bolt; the horizontally-reciprocating bolt E carried by said receiverand carrying the spring-actuated firing-pin 25; the bolt-locking actuator F; the sear 39 for holding the firing-pin in a re-' tracted position; sear-spring 94; trigger and cartridge-shell ejector: thus it will be seen that the entire gun-mechanism, with the exception of the guard block (herein designated v in a general Way by G); the cartridge-packet M; the cartridge-lifter, designated in a general Way by H, and cartridge-lifter-actuating mechanism, designated in a general way by H, is and may be of the same construction, arrangement and operation as in the patent hereinbefore referred to. In the patent referred to, the receiver is recessed vertically to receive the cartridge-case.

The-cartridge-packet case M used in connection with my present improvements and as herein shown, will preferably consist of a casing comprising the two side-walls 170, 171, and the front and

rear walls

172 and 173 respectively, the rear one 173 of which is recessed at 173 to permit the entrance and operation of the cartridge-lifter H. In the preferred form, as shown in the drawings, the cartridge-packet case is constructed for supporting two corresponding and independent [00 columns of cartridges located side by side and in different planes, it being of stepped construction. For this purpose the two side walls of the case are inwardly flanged at their lower ends, as shown at 184'and 185, respectively, the flange 184 being on a lower plane than the one 185. One of the columns of cartridges, shown at the left-hand in Fig. 2, rests upon the lower step or flange 184, while the other column, shown at the right-hand in said figure, rests upon the upper step or flange 185, the step being elevated above said lower step by a distance of about one-half the diameter of a cartridge. In practice, the cartridges are allowed to slightly intermesh, for the purpose of properly steadying one column against and by means of the other. By this arrangement, both columns of cartridges may be fed upwardly in the case by the cartridge-lifting device as hereinafter described, without crowding or jamming therein. As shown in Figs. 2 and 3 of the drawings, both side walls of the packet-case are inwardly flanged to form side lips, 186 and 187, against which the uppermost cartridge of the left and right hand columns of cartridges alternately bear.

The packet-case, in practice, will be so constructed that the side walls will be resilient and bear with sufficient force against the opposite sides of the two columns of cartridges as to hold them against accidental displacement prior to the insertion of said packet in the receiver of the gun,

upper flanges

186 and 187 and

lower flanges

184 and 185 co-acting with the side walls to accomplish this end. This method of holding the cartridges in the case enables the case to be held in the receiver by means of the cartridge-lifter bearing against the lowermost cartridges of the two columns, without the use of the usual catches, and permits the case to drop out of the receiver immediately upon the retraction of the cartridge-lifter.

The packet-case may be conveniently filled either from the top or bottom, as desired, as is fully explained in the application of J. P. Lee hereinbefore referred to.

As a means for elevating the cartridges in the packet-case, I have provided a cartridgelifter, designated herein in a general way by H, which not only elevates the cartridges in the case, but holds the said case in place in the receiver of the gun by means of said cartridges. This cartridge-lever consists of a lifting-arm, 153, having an enlarged tubular journal, 154, at its rear end, and having at its opposite end two laterally-proj ectin g cartridge-seats, 180 and 181, for supporting the lowermost cartridges of the two columns of cartridges of the packet, one of the seats, 180, being on a lower plane than the one 181, the relative heights of the

seats

180 and 181 corresponding substantially to the relative heights of the two lowermost cartridges of the left and right hand columns of cartridges, respectively, as will be apparent by reference to the drawings, in which the relative heights of the two lowermost cartridges are shown by dotted circles.

It will be understood that where a one-column cartridge-packet is used in connection with the gun, the cartridge-lifting arm will be constructed with but one cartridge-seat.

The tubular journal 154 of the cartridgelifter is slotted peripherally atits upper side, as shown in Figs. 7 and 8, Sheet 2, to form a recess, 150, through which the trigger 82 extends, as shown in Fig. 1, Sheet 1. This tubular journal is pivotally supported in a corresponding bearing, 154, formed transversely in the guard-block G, which guard-block is mortised vertically and longitudinally, as shown at 191, Figs. 4 and 5, Sheet 2, to receive and permit the movement of the cartridgelifter between its side-walls. This guardblock, in the preferred form shown in the drawings, is constructed in two pieces, it consisting of the main portion 190 (recessed at its inner face at 191, as shown in Fig. 5, Sheet 2) and a side plate, 192, secured thereto by means of the screws 193 extending through the plate 192 at its either end and screwed into the main part 190, as shown in the figure just referred to. By this construction of cartridge and disposition of the cartridge-lifter, it will be seen that the pivotal bearing therefor is some distance rearward of the cartridge-packet, and that the tubular journal thereof forms a guard for the trigger, which trigger is preferably pivoted between oppositely-disposed projections, 194, formed upon the adjacent faces of the two side pieces of the guard-block, at their upper edges.

As a means for actuating the cartridgelifter H, to elevate the lifting-arm 153 thereof, I provide an actuating-device, herein designated in a general way by-l-I. In the preferred form thereof as herein shown, the cartridge-lifter-actuating device consists essentially of a spring, 161, of suitable power. This spring is preferably placed vertically within the gun-frame, as in Fig. 1, it reacting against an abutment (herein shown as a screw, 155) at the upper part of the gunframe, and taking its bearing against the lug 160 on the rearward side of the cartridgelifter journal 154, said lug being preferably pivotally supported upon a pin, 158, in a recess formed in the said journal.

As a convenient means of supporting the cartridge-lifter-actuating spring 161, I have provided two telescoping members, 159 and 159', the one 159 being pivotally supported upon the pin 158, as before stated, and the one 159 being pivotally connected with the screw 155 through the medium of a ball, 162, at its upper end enteringa socket, 163, formed in the inner end of said screw, bothof said members having flanges, 157 and 157, respectively, at opposite ends, against which the end of the springs abut.

ITO

The breech-piece D of the gun is vertically 13o To permit the cartridge-1ifter-actuating mechanism to be readily assembled and secured in position within the gun-frame, the rear end, 156, of the receiveris vertically bored and screw-threaded to receive the screwthreaded end of the bearing-screw 155; this bore communicates with the recess 156 of the breech-piece, and is of sufficient diameter to permitthe insertion through it of the different parts of the actuating-device H. In assembling the parts of said actuator, the telescopic member 159 will be first pivotally secured to the journal 154 as shown in Fig. 1, after which the spring 161 will he slipped over the stem of said member 159 through the opening in the rear end 156 of the receiver; the tubular member 159 is then passed through said hole and extended into the spring and over the member 159; after which the screw 155 is screwed into the hole in the rear end of the receiver, with its socket in engagement with the ball of the member 159', the parts being then in operative position. By this construction and arrangement of cartridge-lifter-aetuating mechanism, the parts thereof may be quickly assembled and disassembled without disturbing the cartridge-lifter or other of the mechanisms of the gun.

In practice, the cartridge-lifter will be so constructed, and the spring 161 so disposed with relation thereto, that the pivotal or bearing point 158 of the spring will, when the cartridge-lifter is retracted to its full open position, be carried past the dead-center line (shown at c, c in Fig. 1), whereby said lifter will stay in its open position until closed. lVhen closed, the action of the spring will force the

cartridgeseats

180, 181 against and feed the columns of cartridges upward in the packet-case. A stoppin, 182, will preferably be provided to limit the retractive movement of the cartridge-lifter..

For convenience in opening or retracting the cartridge-lifter, thumb-pieces, 183, are formed upon either side of the arm 153 of said cartridge-lifter, in suitable position to be engaged by either the thumb of the right or left hand of the gunner.
