AIR-GUN.

intensa 1 Specification of Letters Patent.

Patented Nov. i 1, wie.,

Be it known that l, ARTHUR V. Dlcnnr, a citizen of the United States, residing at Seattle, in the county of King and State of e lVashington, have invented certain new and useful. Improvements in Air-Guns, of which the following is a specification.

This invention relates to air-guns and,

more especially, to improvements'in the gun of this class which is illustrated and described in United 4States Patent 1,026,303, issued tome May 14, 1912.

The object of my improvements is to provide an extremely ellicient and conveniently ,operated air-gun which will embody rclatively few and colnpactly arranged parts and be 'capable of withstanding severe usage with little liability of getting out of order.

With these ends in View, the invention consists in the improved construction, adaptation and combination of parts, which will be 'described hereinafter, and pointed out .more particularly in the appended claims. In the drawings, Figure 1 is a side eleva- .tion of a gun constructed in accordance with the present invention. Fig. 2 is a vertical longitudinal sectional View thereof. Fig. 3 is a fragmentary side elevation with the cover plate removed. Fig. 4 is a detail horizontal section through 4-4 of Fig. 1.

The reference numeral 5 designates the frame of the gun which is rigidly cpnnected to the stock 6. Secured to the stock is a longitudinally arranged cylindrical ytube 7 5 which serves Aas a reservoir for compressed air, and extending through the tube 7 is the gun barrel 8.

9 is the fore-arm incasing a pump cylind'er 10 which is provided with a plunger The latter is operated by means. of a lever 12 which is hingedly connected to the front end of the tube 7 and is connected by a link 13 to a block 14 Which is slidable upon a guide-bar 15, the block in turn being connected to the plunger bya piston rod 16. When the lever 12 is unemployed, it is se- Cured in juxtaposition with the tube 7 by means of a collar 121 which is moved endwise upon' the pum cylinder to couple the pd olf said lever t creto, as represented in 17 represents a passage leading from the rear, or discharge end of the pump to the interior of the air reservoir 7, (and 18 is a dot extending from said passage to the rear of the gun barrel. VProvided in the pump cylinder' is a spring-pressed valve 19 which serves to prevent the'reverse flow of air from the passage 17 into'the pump cylvalve 20, which is yielding-ly held by a spring 21 in closed position against a seat 201, is provided at the juxictureof the passage 17 and duct 1S.

Provided in the stock 6 and to the rear of the gun barrel is a bullet magazine comprising a tube "22 having au open front end which is connected by a way 23 with a cylindrical. chamber 181 extending transversely through the air duct 18.

The axis of the chamber 181 is disposed in the same plane with thelaxis of the gun barrel. Provided centrally of said chamber is a non-rotatable cylindrical core or plug 24 formed with a bore 241 extending diametrically therethrough and in coincidence with the bore of the barrel. Rotatably mounted upon the core 24 and fitting the peripheral wall ofsaid chamber is a sleeve 25 provided with holes 251 and 252 disposed diametrically opposite each other and are arranged to4 be brought into axial aline' ment with the barrel bore 81 and the core bore 241 when the sleeve is in its normal rotary position, as shown in Fig. 2. When the sleeve is moved into the rotary position in which it is indicated by broken lines in Fig. 3, the hole 251 is presented to the way4 23 to receive a projectile from the magazine.

The bullets, indicated by 26, within the magazine are pushed forward through the Way 23 into feeding positions with respect to the 'sleeve by means of a follower 27 which is urged forward by a helical spring 271. A stud 28 secured to said follower protrudes through a slot 29 provided in the magazine wall Vand is utilized for retracting the follower in o-pposition to spring 271 when the magazine is to be supplied with bullets through an aperture 291 provided therefor in the Wall of the magazine.

Tothe rear of the valve 20 is av chamber 30 containing the main spring 31 tending to press a hammer-'block 32 forwardly to encounter a firing pin 33 which,y in turn, is driven by the spring-impelled block 32 against the valve 20 to unseat the same when' the block is released. lVhen the hammer? block 32 is brought, through the agency of a stud 321, to its rearmost position, it is engaged by a detent 34 which is in the nature of a bell-crank lever having a depending arm 341 which is connected by a pull-rod 35 with the trigger 36. The engagement of said detent with the hammer-block is effected by a spring 37.

Provided on the sleeve 25 is an arm 38 which is connected by a pin 381 to a dog 35) which is connectecsat its forward end with an extensible spring 40 tending to yieldingly retain the sleeve in the position in which it is shown in Fig. 2. This dog is of a length to have its forward hooked end engage the stud 321 which is rigidly connected to the hammer-block and protrudes through a longitudinal slot- 41 provided in the plate 42 secured to the side of the gun,

43 is a Xed pin disposed so as to be encountered by the inclined face 391 of the dog to ward off the latter from the stud 321 as the hammer-block (see Fig. 3) approaches the position in which it is engaged by the detent 34. When the dog 39 is, through the medium of the stud 321, drawn rearwardly, the sleeve251 is presented to the way 23 to receive a bullet, and upon being released, the spring 40 asserts its power to restore the sleeve 25 to normal position (Fig. 2) with the bullet in tiring position. The connection between the spring 40 and the dog 39 is offset to be below the longitudinal axis of the latter in order that the spring will exert a downward pressure at the hooked end of the dog.

To fire the gun, the trigger is pulled, thereby withdrawing the detent 34 from the hammer-block 32, whereupon the main spring 3l becomes operative to drive the hammer-block against the ring pin 33 which is thereby caused to push the valve 20 into open position for the' admission of a quantity of compressed air into the duct 18 to act against t-he bullet and deliver same from the gun.

' What I claim isl. In an air-gun, the combination of a rotary bullet-feeding` element arranged to carry a bullet from the magazine to the rear end of the gun barrel, a hammer block and connections with the feeding element mov-- able longitudinally ofthe gun for effecting the rotary movement 'of said element vinto bullet-receiving position, and a spring for rotating the element into position for discharging the bullet.
