Another object ofmy invention-iste provide a toy pistol in which the mechanical parts are so arranged'that the vpistol simu-v lates in form and yaction a real automatic pistol. y z 'a V lnother object of my invention is to provide a pneumatic toy pistol inwhich the air release means controls also the feed from the magazine.

Still another object of the inventionis to produce a pneumatic toy pistol in .which a selective range of power is 'provided` v With the above and other objects in view, my invention consists in the improved pneumatic toy 'pistol illustrated in the accomthe art tol which my invention relates.- ln the drawings accompanying and forming a part of this specification, andwherein the preferred embodiment of my invention is illustrated: f

Figure 1 is a sectional elevation of my invention. I l

Figure 2 is a plan View in section showing my improved air release mechanism.

Figure 3 is a plan view showing the air chamber partly in section.

Figure 4 is a section of the air chamber taken along the lines 4 4 of Figure 1.

Figure is a perspective View of the key for operating the pistol. A

ln the drawings numeral 1 represents the air cylinder of the gun which is a hollow member permanently closed at the top, preferably oval inform as shown in Figure 2,

and sli htly inclined to form a convenient grip. ttached in any suitable manner to one side of the air cylinder is the barrel block 2 bored, as at 3A to form the barrel of the gun and provided with a hollow cylinmail. aerial no. trama'.

drical bore-.4 comprising. a magazine fork holding the round projectiles or shot 5. Be-

low the magazine is the trigger loop 6 which connects with an elongated guard or cover 7 6o of lll-shaped cross section extending down along the side of the grip and forming therewith an enclosure for the-lower part 8 of the trigger mechanism. Extending rearwardlyfromthe top of the grip member are the ears tween them being preferably filled with a wooden block 10 appropriately shapedto f i finish the grip of the gun.

'.lhe bottom of the air cylinder is closed by the metallic cover plate11. of a-y shape' correspondlng; to that of the 4air cylinder having anges 12 entering withinsaid air cylinder said flanges and cylinder being' apertured with aligned threaded openings 75.

13 for the'reception'of screws 14 which hold said cover plate in place. The middle of ceives in sliding relation thereto a rod 16 of the piston by` .which air is compressed a withln the air cylinder. `Within the air cyl- "17 maintaining the rod 16 in tensioned position inwardly of the grip member. rllhe abut-ment plate 18 is apertured to allow passage therethrough of the rod 16.

Thel piston 17 comprises a vplurality of washers arranged on the reduced end 20 of the rod 16 which end isllattened on one side this cover plate is apertured atl and r'e-v as shown in Figure 2 to cooperate with like shapedapertures through the centers ofthe washers. -By this 'means the rod 16 isprevented from rotation. @ne of the washers is preferably of flexible material lian ed" outwardly as at 21 in order to more e ectively seal the space between itself and the inner wall ofthe air cylinder along which reduced end 20 of the rod 16 by a nut 22 i which has a sloping contour to its upper surface for a purpose hereinafter to be described. rlhe rod 16 is notched at several points along the side facing of the trigger c5 9 arranged in parallelrelation, the space be- .-1

aperture 30. Within the reduced portion of mechanism by means of notches 23, 24 and 25 having sloping -faces as shown. These notches. are adaptedv when the rod 16is" l wall of the air chamber 7 into which it ex-- Its inner end' is closed as shown at 29 except for a squared tends a short distance.

said barrel block is slidably arranged a valve l block 31 which is round in cross section fit- ,11.5,

ting the bore 3 of the barrel in air tight relation thereto-but freely slidable therein as best shown vin Figure 2. The valve block 31 is open at its inner end and closed at its v outer end from whiehprojects a squared .20 30`in the end 29 of the reduced portion, and

valve stem 32 fitting the squared opening slidable therethrough. vA light spiralspring 33 surrounds this stem and vabuts ment 39 and 40 respectively. The abutment 39 has a flat face 4l adapted to push against the shot in the magazine and impel them into the tube 37 causing the foremost shot to v position itself in the bore 3 of the barrel, ad- 70 at one of its ends against the closed end 29, f

theother end being held under compression by la' pin 34 by means of which spring vthe valve block is held normally against' the closed end of the reduced portion of the 'barrelblockL The strengthof this springl is suiiicient to prevent the valve block being opened( by the pressure of the compressed air in the air chamber. The end-of the valve stem is bevelled and adapted tocoact, withv the slopinlg valve bloc when the rod 16 is projected up,-

. wardly by release of the helical spring'19.

At a point remote from its closed end 29 the reduced portion of thebarrel is apervalve block 28 is hollow and apertured at af tured as at 35 to place said barrel'in communication with the air chamber 7. vThe point 36 which is normally out of registry with the aperture when the valve block is in retracted position but adapted to be placed in registry with the aperture 35 wh'en the valve block is moved forwardly a shortv distance, opening communication between I the air chamber and the b ore 3 of the barrel.

The magazine portion of the gun comprises the cylindrical bore 4 com1nunicatin near its inner end with atubular vportion 3 extending at first longitudinally thereof and then bending vertically upward. The ,end of the tubular portion facing the magazine is flared to facilitate vthe entrance ofshot therein. This tubular portion opens into the bore 3 of the barrel member 2 at a point immediately adjacent the open end of the valve block 27 when the latter is in normally retracted position. When the valve block is actuated in the manner hereinafter described it is adapted-to overrun the tube 37 and cut ofi' its communication with the bore 3: Within the magazine is a spiral spring 38 attached at each end to an abutjacent the open end of the valve block. The other abutment has an external portion 42w Servn as a knob o1 handle by which the magazine is opened, and is provided with a pin 43 working in a bayonet slot 44 adjacent the outer end of the magazine member by which the knob 42 is secured in place in the end of said member.

The upper end of the trigger mechanism 8 comprises a finger piece 45 integral therewith exposed within the trigger loop G, said trigger being pivotally secured by the pin 46, within the tubular guard 7 A leaf spring 47 lies in a recess in the back portion of the finger piece 45 and reacts between said finger piece and the outer wall of the air chamber 1. This leaf spring maintains the lower end 26 of thetrigger in engagement with the rod 16 and impels it into engagementy with one of the notches 23, 24 or 25 when the rod 16 is pulled outwardly from the lower end of the air chamber 1. The lower end vof the rod 16 is provided with a head 48 transversely apertured at 49 for the reception of the key or operating transverse handles' 51 'on opposite sides contour of the nut, to open said .4 ed to fit withln the aperture 49.

ytively. chosen by the operator according-to block is again permitted to retract by withthereof andan angular projection 52 adapt- In the operation of the device the rod 16 is withdrawn until the .lower end of the trigger 26 falls into one of the notched portions ofthe rod,the notches being selecl0 the degree of compression desired. When the finger piece 45 is pressed inwardly the trigger piece 26 will be withdrawn from the notch with which it was enga d permitting the piston to be forcibly lmpelled by the helical spring 19. This compresses alr in that portion of the air chamber between the piston and the upper closed end of said air chamber. At the moment the sloping surface of the nut comes in contact -with the valve stem 3l it causes the valve block to be moved outwardly against the tension of the spring 33 putting the aperture 36 of said valve block into registry with the operture 35 in the reduced portion of the barrel permitting-a sudden release of the compressed air through said apertures against the shot which lies adjacent the open end of said valve block driving said shot through the barrel of the gun. -The sameforward motion of the valve block closes the upper end of the feed tube 37 and prevents another shot from taking the place of the one just fired until said valve .iat-nere drawal ofthe nut trom cI intactV- with v, the I beveledemi `of the,fsame.f f lilhe magazine .is load'edfby.jturnlngl the knob luntilfthe pin "i3" congresw in; alignment; with the longitudinal portion oi the '[bay-4 oneft slot vthen withdrawing Vthe knob t2 with 'the sprin '38 and the abutment il'. .The
