FIREARM.

Application filed September 11, 1924, Serial No. 737,035. Renewed November 19, 1927.

This invention relates to firearms and is particularly adapted for use on firearms of the type shown in the Patents 719,955, Feb. 3, 1903, and 789,755 May 16, 1905, to John D. Pedersen. These patents disclose a firearm of the magazine type, particularly adapted to accommodate shot shells. Such shells or cartridges are loaded into a tubular magazine from the rear end thereof, and are retained therein by a stop or lug consisting of a stiff spring attached to the carrier. As the forearm and action bar are retracted in the operation of loading the gun, the carrier is rotated to release the rearmostcartridge from the stop, said cartridge then slides rearwardlyonto a suitably constructed part of the carrier. On the forward move ment of the action bar the carrier is usually rotated to elevate the cartridge into alignment with the chamber, and the stop lug is thereby brought into position to engage the base of the next cartridge. The lifted cartridge is pushed into the chamber by the The firing pin and cooking ment of the action bar, and as the action bar and breech block reach their final forward positions the action bar is locked against another rearward movement until the hammer has moved forward to fire the shell in the chamber.

'In this gun as hitherto constructed, in order'to remove shells from the magazine without firing them, it has been necessary to release the action bar lock by means provided for this purpose, and to repeatedly operate the action bar, each shell in turn passing through the same series of movements as though it had been fired, or by careful manipulation each shell may be removed from the position in which it is elevated into line with the chamber but has not yet entered the chamber. This necessity arose from thefact that shells were retained in the magazine by a latch of such construc: tion that it could not be readily displaced.

Even the operation of loading the magazine was difficult owing to the necessity for forcibly-displacing this semirigid latch memher.

One object of this invention is to provide an improved means for retaining shells or cartridges in the magazine,

A further object of this invention is to provide means whereby shells or cartridges may be removed directly from the magazine without operating the action bar.

A further object of the invention is to provide an improved cartridge or shell stop which can be manually moved to ineffective position, thereby permitting the removal of the shells in the magazine.

With these and other objects in view my invention consists in the novel combinations and arrangement of parts hereinafter described and illustrated in the drawings.

In said drawings Fig. 1 is a vertical longitudinal section through the receiver of a firearm embodying my invention.

Fig. 2 is a horizontal section on the line 22 of Fig. 1.

Fig. 3 is a perspective of my improved shell carrier and stop showing this member in engagement with the head of a shell.

he receiver 10 which encloses the main parts of the operating mechanism, has an opening 11 at the bottom to permit of loading and ejecting the shells. The breech block 12 when at the limit ofits forward movement engages a recoil shoulder 13 on the receiver frame, locking the breech block against rearward movementuntil released from said shoulder. The breech block is recessed to receive a firing pin 14, inserted therein from the rear, and terminating at its rear end in a cocking head 15 comprising a shoulder 16 adapted to be engaged by a sear 17, which is held in engagemei'it with shoulder 16 byj a sear spring 18. The scar comprises a laterally extending foot 19 which extends under the forward end of the trigger 20.

The breech block is adapted to be reciprocated thru its connection with a forearm 21, which encircles a magazine 22 adapted to receive a column of cartridges. The forward cartridge in said column engages the plunger which is pressed rearwardly by spring 24. The means for retaining shells in the magazine and for transferring them one at a time from the magazine to position to be pushed into the chamber by the breech block, will now be described.

carrier comprising a spindle 25 having a wing or blade 26 rigid therewith, lies in a longitudinal recess in the Wall ofthe receiver 10, and is journalled in the ends of said recess for rotation about a longitudinal axis. Integral with the spindle 25 near its rear end is a spiral cam follower 261, adapted to engage a cam groove in the breech block. Fixed to, the carrier is a guide lug 27 which forms a lower support and guide for the b e l k ur ng: th major par of its movement. Pivoted on. the carrier near its forward end is a shell stop or latch 28, adapted when said carrier is in normal position, to retain the Shells in the magazine by engaging the head of the rearmost temperarily retain the shells when the car, rieris rotated so that latch28 is ineffectivefor this purpose, aswill be presently explained; The operation of the carrier is, as follows: r f

WVhen the breech block is forward the carrier blade 26' stands vertically at one side o f'th'e beech block, in a recejss'in the receiver wall. As the breech block moves rea'rwardly. the carrier remains in this position'ywhile the shell in the chamber is extracted and ejected downward past] the carrier'by the spring pressed ejector 31. After this has occurred, and very near the end of the rearward; movement of the breech block I the carrier is rotated-by the engagement of spiral cam 261 with asuitably shaped part of the cam groove262 on the breech block.

h m me Places he arr er blade S stantially transversely'ofthe receiver, in

which position it isa dapt ed to receive the I shellto'b'e released from the magazine. Near the end of the carrier movementthe pivoted stop or latch 28 moves laterally off the head of the reai'most shell, which shell under the pressure of the magazine spring-29 moves back'onto the carrier, the next cartridge in front'being stopped bytem'porary catch 30. As the breech block begins to move forward the.ca rrier is reversely. rotated, lifting the shellthereon into alignment with the her. The carrier does not return atonce to its normal inactive posltlon. lnfthe recess in the receiver wall, but remains in a position in which it supports-theshell between the, breech block and, the chamber while thev breech blockadvances and begins, to slide, the

shell into the chamber, the icontrolling.cam groove 262011. the; breech block being, snitably shaped for this purpose. At thelprop'er time the carrier returns to. inactive position, the rearmost shell in themag azine resting against the latch '28, tijo-n is complete. V

My invention renders it possible to unload the magazine without operating the action bar at all. The shells in the magazine are retained solely by latch v 28, which latch is held in effective position by a comparatively light spring 29. Latch 28 can, therefore, be manually retracted at will to releasethe. rears m st Sh l, which Shell: is then removed, and the operation repeated for each shell in the magazine. The pivotal mounting of this latch also permits its ready deflection 1n loading the magazine.
