'MAGAZINE non AIR GUNS.

Application filed muy 15,

My invention is an improvement in air guns or rifles of that particular class in which the pellet or projectile is moved into the barrel for firingv by meansof a lsliding bolt, and relates more especially to the provision of a magazine attachment to facilitate loading and iirin'g the gun Comprising a device cooperating with they magazine chamber for bringing the pellets or projectiles successively Vinto position tor the operation of the bolt preliminary to tiring.

The'primary object ot my invention is to provide a magazine attachment for a single shot gun or rifle that can be easily and conat small expense, will not increase the size' of the rile to lanyy material extent, may be quickly operated to transfer the pellets or projectiles one at a time from the magazineto proper position for the action of the sliding bolt, and in whichv the parts constituting the magazine vand pellet feeding` device or carrier will not trom the .neat and trim appearance of the gun or rifle.

These and other .objects and advantages ot my invention will be apparent.y from they following description ot the construction and operation ot the magazine attachment. and what 1 nparticularly claim as 4new anddesire to fully protect by Letters-Patent is particularly set Forth in the appended claims.

-tangular .in cross-.sectiomiwith a reciprocating plunger 26 mounted therein andadapted ,atI time, from the magazinechamber 20 Afor carrying a pellet, when said plunger is-Y manipulated, to aspo- .'sitionin,line'ivitli` thegun barrehkand to receive anddeliver the A`pellets, the front wall ef sind 25e-45a 'einen the chamber is atiixedor formed integrally and against which the bairel abuts-is provided with openings (see Fig. 3) communicating with the magazine and barrel respectively, and with an opening 28 in the rear wall thereof on a line with its companion opening in the front wall leading to the barrel, the last mentioned opening, 28, receiving the sl iding-bolt 17 by which the pellet is forced into the gun barrel. .The plunger 26 is provided with a recess 30 extending transversely through the same to receive the pellet from' the magazine chamber, said recess being of a size to correspond with that of the pellet, and in order to project the plunger' to a normal Aposition with the recess 30 in line withthe magazii'ie chamber a 4compression spring 3l is interposed between the inner end of said plunger and the closed end 25 ci" the casing 25, being' retained on a pin 32 projecting inward from said end wall and working in acavity 33 in the adjoining end of the plunger in. which the spring is seated. rl'lie outward movement of the plunger by the action of the spring is limited by means of a spring linger 3asecured on top of the casing and having a downwardly bent end 34 adaptedto engage a shoulder 35a on the plunger at the inner end of a groove in which said bent end of the linger travels Vin the operation ofrsaid plunger.

To hold the pellets in the magazine chainber so thaty they may be properly and regularly fed into the feeding device or shuttle l' provide a spring-actuator detent comprising a spring member 36 secured on the magazine chamber and having a pin 37 projecting through an. aperture therein to engagev the spool-shaped pellets successively as they gravitate to the inner end of the magazine chamber, that is to say this detent holds or engages the second pellet from the inner end of the magazine chamber with the lirst free to move into the recess in the plunger, and in order to release the engaged pellet automatically when the plunger is pushed in by the operator-s thumb to bring the pellet carried by said plunger in alinement with the gun-barrel the rear end of the spring member 36 is extended over the casing 25 so as to be engaged and lifted by a cam projection 38 on the outer end of the plunger; it'being understoodthat in thisoperation the muzzle of the gun is pointed upward so that the pellets will gravitate towards the shuttle, and that during the return movement of the plunger by the action of the spring 3l the pellet at the inner end of the magazine chamber will bear against the side of said reciprocating plunger to enter the recess 30 therein when the plunger returns to normal position to receive this pellet, the adjoining pellet being engaged by reason of the spring member 36 being released from the cam projection to thereby lhold the re- Lezasio maining pellets in the magazine chamber from crowding or otherwise interfering with the'operation of the shuttle.

The magazine chamber is provided at its outer end with a conventional arrangement Afor charging the same, in the form of a cap or casing, as shown in Fig. 2, to maintain the neat appearance of the rifle when it is loaded and ready to lire, aswell as when it is unloaded and not in actual use, in the latter instance it being necessary only to slide the bolt forward after pressing the plunger in so that it will engage the pellet receiving opening in the plunger and hold said plunger against the action of the spring.

rThe construction and operation ofthe magazine attachment for pneumatic :rifles will be readily understood from the forego-` ing description in connection with the accompanying drawings, and'it will be obvious that it provides for converting a Vsingle shot riiie into a magazine rifle and for quickly shifting the pellets 'from the magazine chamber to the barrel for firing, the operator being required to merely elevate the muzzle of the rilie andpusli the plunger in by his thumb to bring the pellets successively into position to be forced into the inner end of the barrel by the sliding bolt while the spring at the rear end of the shuttle casing returns the plunger to its normal position when the bolt is slidbaclr after liring, the spring member on the magazine chamber then operating automatically to engage one of the pellets for the loading' operation hereinbefore explained.
