GEORGE W. G-RUVER, OF BAKERSFIELD, CALIFORNIA.

FIREARM.

To all 'whom z'z may concern.'

Be it known that I, GEORGE W. GRUVER, a citizen of the United States, residing at Bakersfield, in the county of Kern and State of California, have invented a new and useful Firearm, of which the following is a specification.

This invention relates to an improvement in firearms, the primary object of the invention being the provision of a knockdown magazine orrepeating firearm of the hammerless type, in which the barrel `and magazine are carried by the forward removable portion of the stock, and the forestock and the receiver carried by the butt stock is provided with means, whereby the two may be placed into sliding engagement and locked in operable position by means of the magazine.

A further object of the invention, is the provision of a means whereby the spring closure piece of the breech mechanism, can be held in open posit-ion bythe breech mechanism, so that the spring o-f the magazine will automatically eject unused shells or cartridges when it is desired to unload the said magazine.

Another object of the invention is the provision of means operated by the breech mechanism when ejecting a used shell or cartridge for delivering the unused shell or cartridge from the' magazine and simultaneously locking the next shell or cartridge in the magazine.

A still further object of the invention is the provision of a breech mechanism, which comprises a receiver connected to and carried by the stock of the firearm, a frame carrying the hammer, shell or cartridge guide and loading means, and the actuating lever, the breech block, and the barrel and magazine carrying portion, thus making the entire gun or firearm in four pieces, the main carrying frame being removably mounted sothat the hammer and other adjacent mechanism can be easily cleaned, renewed and repaired.

Vith the forego-ing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with- Specification of Letters Patent.

in the scope of what is claimed without depart-ing from the spirit of the invention.

In. the drawings:-Figure 1 is a vertical longitudinal section of a fire-arm embodying the invention, and having one side of the main casing removed and the barrel and magazine portion in elevation, the breech mechanism being in the position it assumes when the vbarrel is loaded and the hammer set back and held at safety. Fig. 2 is a sectional view with the hammer in fired position, the breech block being in section, and the hammer also shown partly in section. Fig. 3 isa bottom plan view of the forward end of the frame or receiver. Fig. 4 is a view similar to Fig. 1, on a larger scale, with the breech mechanism in the position it assumes when having ejected a used shell, and about to feed an unused one to the barrel. Fig. 5 is a section taken on line i12-w, of Fig. t. Fig. 6 is a cross section taken on line ca of Fig. 2. Fig. 7 is a detail section taken online g/-g/, of Fig. 2. Fig. 8 is a detail view of the breech block and the locking and actuating arm of the breech-operating lever in forward locked position. Figs. 9 and 10 are views illustrating the unloading of the magazine. Fig. 11 is a detail perspective view of the frame or receiver of the breech mechanism. Fig. 12 is a detail perspective view of the breech block. Fig. 13 is a detail perspective view of the breech-operating lever. Fig. 14 is a detail view of the main frame which carries the main portion of the mechanism. Fig. 15 is a detail perspective view of the cartridge lock and elevator. Fig. 16 is a detail perspective view of the hammer. Figs. 17 and 18 are detail views of the safety lock and spring. Fig. 19 is a perspective view of the trigger.

Referring to the drawings, A designates the butt end of the stock, B the barrel, C the fore stock, which carries the barrel B and magazine D, the frame or receiver E, being connected to and carried by the butt end A, and provided with means which coacts with the portion C, to permit the gun to be knock-down. As shown the receiver Eis provided at its forward end with the flat bridging portion e, and the narrow strip c, the two grooves e', forming guides for the reception of the parallel guide strips b', carried by the portion b, of the fore-stock C, of the gun. The magazine D, as shown is rotatably mounted in the fore-stock C, and is limited against inward movement by means of the shoulder 1, at its milled outer end, the port-ion 2, being adapted to be rotated to engage the threaded portion 3, of the receiver E, and thus lock the gun assembled. To knock down the gun, it is simply necessary to turn the magazine by gripping its milled outer end until the threaded portion 2 thereof is free of the threads 3,v of the receiver E, and the forestock C, can then be pulled upwardly and out of engagement with receiver E, thus making two members, one carrying the barrel and magazine, and the other the breech mechanism. rllhe receiver E, as before stated is carried by the butt end A, of the stock, and has removably incased therein from the bottom, the main frame F, having the stock engaging end F and provided with the hammer pivoting lug 100, the breech-lever limiting lug F, also being integral therewith.

Secured to the forward upper portion of the casing or frame F, is the pair of supporting plates 4, which are arranged in parallel, and have their rear edges 4, bent inwardly to form a stop for the unused shell or cartridge before being inserted into the barrel. The spring clips 4a and 4", are also carried by these plates 4,' and upon one of the plates upon its outer face is mounted the hinged plate 5, of the spring actuated closure or loading trap 6, this being in line-with the inner end of the magazine D. Pivotally mounted upon the pin 9, is the cartridge carrier 8, whose forward end is forked and provided with the shouldered enlargements 8c, the cartridge stop 7, being pivoted to said carrier 8 at 8', and having its pointed and shouldered end 7 and 7, normally held downward upon the forward end of the frame F, by means of the spring 8, so vthat when the parts 8c, are in either of the positions as shown in Figs. 2 and 4, the shoulder 7, will always act as a lock to prevent the next unusedA shell within the magazine from moving backwardly and clogging the breech mechanism. This cartridge carrier 8, as clearly shown, is provided with two lugs 8a and 8b, near its pivotal point, these being disposed in the path of the shouldered portions 11a and 11b, of the breech operating lever 11, whose hand grip 10, is formed integral therewith. It will thusv be seen that `a movement of the hand grip l0 toward the stock will cause the shoulder 11a to abut the lug 8b, and cause the carrier 8, to move from the position, as shown in Fig. 4 to the position as shown in Figs. 1 and 2, the gun now being loaded and ready for liring. A movement of the actuating lever 10 in the opposite direction, will after moving the dist-ance between the shoulder 8a and the shoulder 11b, finally bring these shoulders into engagement, when the carrier 8 will be affected and moved from the positions shown in Figs. 1 and 2, to the position shown in Fig. 4, the used cartridge shell having been ejected and an unused one at this time being upon the forked ends of the carrier 8 and ready for delivery to the barrel.

As shown in Fig. 4, the knobbed end 11, of the breech operating lever 11, is disposed below and in line with the groove or slot formed by the

shoulders

12 and 12, in the rear end of the breech block G, and when the actuating lever 10 is moved upwardly toward the stock, the knobv end 11 will enter said groove between the shoulders 12 and 12', and carry forward the breech block G, untilthe guide grooves g', fit over the strips g, of the receiver E, at which time the firing pin 15 will have its point 15 in line and slight Contact with thty percussion cap of the cartridge. Simultaneously with this movement, the lug 14 anc` shoulder 14', engage the notch 14 and the curved portion es, of the receiver E, and the breech block is now in place. To revent the accidental movementA of t-he breech block G when in this position, the spring actuated pin 13, seats within notch 11a, of the lever 11, and in this posit-ion the lever 11, forms a lock for the breech block G.

As the breech block G is moved forward into firing position, Figs. 1 and 2, the spring clips or extractor 16, will engage the rim of a shell or cartridge which is now in the barrel; and when -the breech block G, is pulled backwardly, these clips carry with the breech block G, the used shell, the lower ejector 16 giving a snapping action to the lower edge of the rim, and thus throwing the used shell through the top opening in the frame or receiver' E. Upon the underside of the breech block G, is a spring actuated cartridge stop 17, pivoted at 18, and having the spring 19, this coacting with the shoulder 8?, to lock the unused cartridges within the magazine D, and preventing any movement thereof while the gun is loaded or after firing, thel movement of the breech block G, to unload the used shell, tilting the owter end of the firing pin so that the end 17, of the stop 17 will movey above the unused cartridge in the magazine and permit the spring of the magazine to feed said cartridge below the block and back against the projections 4, where the forked end of the carrier 8, will linally raise the forward end of the said cartridge, so that when the parts are in the position shown in Fig. 4, the cartridge is pointing for the barrel, and has its butt end in a position to be pushed ahead of the breech block G, when it is moved to the position as shown in Figs. 1 and 2, the cartridge stop 7 during this period having its shoulder 7 upwardly and backwardly to coact with the projection 8d, of the forked end of carrier 8, thus preventing the next cartridge within the magazine from passing under the breech mechanism, the next cartridge abutting the said shoulder 7, and projection 8d, and being held thereby Within the magazine. The depending sides 20 of the breech block G are guided upon the upper edges of the strips or plates 4, the spring clips 4"l and 4b, assisting in holding the breech block within the plates and above the carrier 8 and stop 7.

Mounted upon a pin 22, between the lug 100 and the side of the frame or receiver E, is the hammer 2l, which is provided with the spring actuated trigger engaging pawl orpin 21, the tiring pin striking shoulder or end 2l and the shoulder 21a, which is adapted to be engaged by the lever 1l, so that when the actuating lever l0 is moved away from the stock during the ejecting of a used shell, the hammer is engaged by the lever l1, and also by the breech block G, and moved against the tension of the spring 23, so that it is finally moved from the position shown in Fig. 2, to that shown in Fig. l. The spring 23 has two

terminals

23 and 23, which engage the receiver E and hammer, respectively. Vhen the hammer is moved from the position of Fig. 2 to that in Fig. l, the spring actuated pin 2l will snap over and be engaged by the shoulder 24 of the trigger 24, and by reason of the trigger spring 25, the hammer will be locked in set position. In order to lock the hammer inV this position, or at what is termed safety, that is so that the trigger 24 cannot be moved to release the hammer 2l, the rearward projection or lip 24a, is engaged by the lower end 26', of the lever 26, which is pivoted in the receiver E, intermediate of its ends, and has. its upper end 26, mounted in the groove 27 of the slidably mounted safety clip or thumb-button 27, mounted upon the exterior of the casing E, in ready access to the marksman. The position of the parts when at safety is shown in Fig. l, while in the position as shown in dotted lines in Fig. l, the pivoted catch 26 is out` of engagement with the lip 24a, and any pull upon the trigger 24 will release the hammer and permit the hammer to assume the position as shown in Fig. 2. The spring 27 holds the thumb-button 27 downwardly in place on the receiver E. f

`As is often the case, it is desirous to remove the unused cartridges from the magazine D, and usually to do this, it is necessary to repeat the actions or operations of loading and unloading of the barrel B, and an accidental discharge of the gun may and often does occur, so in order to make unloading of the magazine easy and safe, the trap 6 is pushed inwardly and the actuating lever 10 is moved downwardly about one-half the distance required to eject a shell, at which time the shoulder 17 will be in line with andengage the hinge plate 5. This action inclines the trap '6 inwardly and in line with the inner end of the magazine D, giving free egress to the unused cartridges within the magazine, which by reason of the spring tension exerted thereon, will be pushed against the inclined trap 6, which guides the cartridge through the opening e, of the receiver E, and out of the gun. Thus the cartridges may be loaded and unloaded through the same means. This part of the invention is clearly illustrated in Figs. 9 and 10. Should there be any used or unused shell or cartridge in the barrel, after the last unused cartridge has been automatically ejected from the magazine, the actuatinglever may be moved still farther away from the stock, and the shell in the barrel will be ejected in the usual manner.

As shown and described, the fore-stock C carries the barrel B, and the magazine D, the rear end thereof itting within the end of the receiver E, as clearly shown in Figs. l, 3, 5, 6, and 10, where the receiver and fore-stock are shown operatively connected.
