AIR GUN.

Specication of Letters Patent. Patented Jan. 24, 1922.

Application led November 15, 1919. Serial No. 338,398.

To all whom t may concern Be it known that 1, FREDERICK HUMBERT Fainwnafrrmn, a citizen of Canada, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Air Guns, of which the followirnT is a specification.

My invention relates to improvements 1n air guns, and the object of my improvement is to provide an efficient manner of compressing the air and retaining the compressed air, to provide a magazine that is operative with projectiles in the form ot' bullets oil spherical form and means for retaining the bullet in the firing position with the muzzle depressed, to provide a breech mechanism that permits of the use of difi'erent types of projectiles, having convenient means Yfor loading, and a stock structure oit a Aterm that is cheap and convenient to in anu facture.

ln the accompanying drawingzw- Figure 1 is longitudinal sectional elevation along a vertical central plane, with the parts .in the loaded position, 'ready to di,"- charge.

Figure 2 is a transverse sectional view on Vthe line 2-2 of Fig. 1.

l `igure 3 is a transverse sectional view on the line 3--3 of `Fig. 1.

Figure all is au enlarged view ot certain parts shown in Fig. 1, showing the magazine mechanism and showing the breech in he open position.

Figure 5 a plan view of the breech, showing the locking device.

Figure 6 is a "fragmentary sectional view, corresponding to Fig. 1, showing a modification of air retaining valve structure.

Figure 7 a diagrammatic view of the parts that form the toggle structure for locking the plunger tor l'iolding` the air under compression.

My improved air gun comprises a stock 10 that supports the different parts, consisting or the barrel 11, air compressing mechanism 12, valve mechanism 13, and a magazine 14, the barrel 11 being so mounted as to have longitudinal sliding movement and a rotative movement relatively to the stock for providing access to the interior of the breech 15 for the purpose of loading with darts and other special projectiles, other than spherical bullets.

The magazine 14 is at the front end portion of the stock 10 and the barrel 11 is operatively mounted by its rear end p0rtion on the upper side of the said magazine.

The butt 16 is at the rear end of the stock 10 and has on the under side a recess 17 that is of suitable form for housing the air compressing mechanism 12.

Intermediate the butt 16 and the magazine 14, is the shank portion 18 of the stock 10, which is crossed generally vertically by a chamber 19 in which is housed the valve mechanism 13. The said vertical valve chamber 19 is extended outwardly for con` necting with the rear end portion of the bullet chamber 2O and housing the front end portion of the collapsible rubber tube 21 and a passage 22 serves to house the rear portion of the said tube 21.

The rubber tube 21 connects the front end of the air compressor cylinder 23 with the said rear end portion of the bullet chamber 20, passing through the valve chamber 19, where it is engaged by suitable valve devices 13.

The said valve devices or valve mechanism 13 correspond generally to the :form shown and described in the patent issued to me July 8, 1919, No. 1,309,321, comprising a backing plate 24 on the upper side that closes the upper side of the chamber 19, against which the tube 21 is forced by the reciprocating plunger 25, positioned on the lower side of the said tube 21. i

The plunger 25 is capped on the upper end, that engages with the tube 21, by a rubber cushion head 26 and has a notch 27 in the side 'for receiving the upper end of the pivoted trigger lever 28 for being locked in the upper position for holding the tube 21 compressed, the said trigger lever being operatively engaged by a spring plunger 29 that serves to position the same for cooperation with the valve plunger 25.

In the form shown in Fig. 1 the effectiveness of the valve mechanism 13 is improved by means of an inwardly projecting rib 30 that is opposed to the cushion head 26,

whereby the tube 2l, when the valve parts are engaged, assumes the torni of a reverse curve. As shown in Fig. l the rib 30 is termed by means ot' an inward bend or indentation ot the backing plate 24.

ln the modified .form ot trigger and valve mechanism shovvn in Fig. 6 the rib 30a is in the form of an outward bend of the backing,v plate 24a, so as to form a concave seat on the inner side and the cushion head or pad'Q/G that cooperates therewith has a rounded upper end.

The cushion head 26a is rigidly mounted on the upper end of a swinging member 3i that is pivotally connected by its lower end with the upper end of the trigger 1rever 25@4 that is mounted on the pin 32, the lower end of the said trigger lever 25"L being exposed and accessible for operation as the trigger. The swinging member 31 serves as the valve device for collapsing the valve tube 2l, the cushionhead 26, that is made ot rubber, serving as the contact portion that contacts with the said tube2l and being adapted to yield slightly so as to permit the parts 4to be shiftedbetween the locked or valve-closing position vand the open position.

The interior Wall structure oit p ber'19a, in'vvhich the swinging' member and the body portion ot the trigger lever 25 to which it isconnected are operatively housed', is` oft suitabie form igor limitino; the movement of these parts to the extreme positions, comprising as one extreme the locked and valve closing position' shown in iuli lines in Fig. 6, and the open position as the other extreme, and indicated by broken lines in the said Fig. 6.

As described, the swinging member 8l and the triggertlever 25@ cooperate as a toggle device, so that an increased power effect is obtained in the' reverse movement ot the trigger lever in the final stages of,collapsing` the tube 21 that compensates Vtor the relatively increased resistance usually involved in operating on the said tube 2l during?,- such iinai stages. f i

The air compressing' mechanism l2 coinprises the cylinder 23 that is open at the rear end and terminates at the iront end inthe form of the nipplek 33 that receives the end ot the rubber tube 2l.

The piston 84 that operates in the cylinder the cham* V23 is provided on the iront end with packingf;

35 of cupped form, oi leather or cclluloid, after the manner ot' packing hydraulic pis-- tons7 and at the rear end is connected with the link 36 by means of the pivotal pin 37'.

The linlrSG extends rearwardly from the piston 34 and has its rear end pivotally connected by means of the pin 3S with the .trent end of the rear brancher arm 39 of the bell crank lever 40 that is` pivotelly connected to the stock l0 at its rear end by means oi the pin el. The front portion of the bell crank lever l0 is bent and shaped suitably to serve as the operatingI handle 4:2, 'which in one position, corresponding` to the position oi: compression or the air in the cylinder, engages with the opposed portion. ot the stock l0, so as to serve as a stop for limiting' the movement of the parts and locking the said parts, in cooperation with the resilient or spring` etect o. the compre, sed a in the cylinder, being the position shown in Fig. l. The linlt 75 3G and the arm 39 cooperate as toggle mem bers, beine` brought to a. position back ot the line oi centers nnen locked in thev manner described, and as indicated in Fig. 7.

The parts are shoivn in the open position by the broken lines in F l.

rEhe line of centers is indicated by the dash line in Fig.

rl'lhe advantage oiA the toggle effect in the operation oif the bell crank comiiressingr lever et() corresponds to that oi' the toggle in the trigger and valve device described and shown in Fig. 6, in that there is increased poiver eitect in the iinai stages to compensate torthe increased resistance due to thev high pressure ol'? the confined air.

rihe breech structure. i5 is in the 'form of a tube or sleeve that is seated in a depression 3 inthe stock i() and in the bore thereof enter-cd the ront end ot the tube SO that contains the bullet chamber 2O and the rear end 'ot the barrel ll, the said tube 'J being tine f secured Within the end tion ont the said and the barrel ll i ing slidahly housed in the iront portion reet'. The rear part oifsaid 'front portion oit the bore is designated by the chaiacter e?, and serves as Vthe projectile rcceivin@ chamber.V
