.6 claims. (o1. 124-30)V This invention relates particularly Vto a toy simulating a repeating rifle.

It is an object of the invention to provide a toy gun or the like having simplified means whereby the cooking of the gun for ring permits a new projectile to be fed into the chamber.

It is another object of the invention to provide a toy of the class described, having an improved trigger mount and magazine section.

It is still another object of the invention to provide a toy gun or the like having improved spring propulsion means for the projectiles.

It is still another object of the invention to provide a toy gun of themagazine repeating type, constructed of a relatively few parts which may be assembled by unskilled labor.

It is another object of the invention to provide a toy gun or the like which has but very few exposed moving parts, and which will therefore operate for long periods of time with freedom from' mechanical diiculties.

In the accompanying drawings:

Fig. 1 is a plan view of a gun embodying the invention, a portion of the stock being cut away to show typical fastening means therefor;

Fig. 2 is an elevation, taken in section on lines 2 2 of Fig. 1;

Fig. 3 is a, vertical section taken through the' magazine and trigger mount on lines Fig. 2;

Fig. 4 is a perspective of a portion of one of the stock members;

Fig. 5 is a perspective of the trigger guard and magazine receiver, the trigger having been removed, and a portion of the guard having been broken away to reveal concealed structure; and

Fig. 6 is a perspective of a portion of the barrel of the gun.

Referring to the drawing, the toy gun embodying the presentinvention includes a stock I0 which is formed of mating half-portionsl I and l2, a barrel I3, a combined magazine receiver and trigger mount I4, and a cooking piece I5.

The stock portions are formed from at wood pieces of suitable thickness and are prelim'inarily cut to shape on a bandsaw or the like. An upper surface I6 of each piece is planed smooth and provides a gauging surface on which the stock portion may be supported for movement into a routing knife which cuts a longitudinal semicircular groove I 'I. The diameter of the groove I'I is equal to the outside diameter of the barrel I3. In a circular saw or other conventional means, a square-end pocket I8 is formed in the inner wall of the stock member, preferably at right angles 55 to the axis of the groove I'I. Each stock portion is similarly made, and when assembled, provides a lengthwise tubular passage within which the barrel I3 is ultimately confined, and a transversely extending pocket which accommodates the trigger guard and magazine receiver. Suitable sanding and other nishing operations may be employed to bring the stockto ultimate form and curvature.

The trigger guard and magazine receiver is formed of two mating half-sections shown in perspective in assembled position in Fig. 5. Each half-section is advantageously formed by diecasting, and provides vertical end walls 2I-2I, a side wall 22, a bottom wall 23 and one half of a trigger guard 24. The-bottom wall 23 is cut away to provide a passage 25 throughl which the trigger may pass, and each side wall 22 has a hole 26 to receive a trigger pin.V

The trigger 28 is placed in position through the opening. 25 formed by the respective halfportions of the trigger guard, and is pivoted therein by the freely mounted pin 3D. A mousetrap spring 3| is positioned as shown in Fig. 2, to urge the trigger into counterclockwiserotation. The trigger has a nose portion 32, the upper edge of which is sloping, and the rear edge of which is preferably squared to form an abutment to retain the projectiles 33 in ready to re position, as shown in Fig. 2. Accordingly, the barrel I3 has a notch 34 formed in the lower part thereof, to permit the entry of the nose of the trigger.

As shown in Fig. 6 the upper half of the barrel I3 is cut away for a length slightly greater than the overall length of the magazine receiver, to form a passage 35 through which the projectiles may fall to enter the firing chamber. As is shown in Fig. 5, each end wall of each half element forming the magazine-receiving chamber has quartersectional arcs respectively 33, 31, which are concentric. The radius of the upper arc is the same as the inner radius of thebarrel, whereas the lower arc has a radius equal to the outer radius of the barrel. Therefore there is a jog or shoulder 38 which represents the wall thickness of the barrel. The insidefaceto face distance between the end walls of the magazine :receiver is equal to or very slightly less than the overall length of the magazine 46.

Within the barrel there is slidably mounted a hollow tubular plunger 45 having a flanged end 46, the outer diameter of which is suiiciently smaller than the inner diameter of the barrel to permit free movement therealong with minimum 91 binding. The barrel is closed,- by a suitably aixed plug 41, and confined about the plunger 45 and between the plug 41 and the inner wall of flange 46, is coil spring 48. Plug 41 has an axial passage through which extends a rod 53, terminating in a head 5I which is free to slide within plungerA 45; and` which` may eng-age with the end wall 52"f'sa-idpii1nger 45 The cocking piece l5 is affixed to the projecting end of rod 5U. Desirably a bumper 54 of rubber or other soft material is interposed between the piece I5 and the outer end of the plug 41.

Assuming the spring and plunger eler'nents' to" have been assembled withirrY the barrel as above stated, the barrel is placedz .respect to one of the half portions of the magazine` receiver and trigger guard so that the cut away portion 35, which is coincident with theoutsidel to outsidewall spacing between the end walls of said magazine receiver is properly positioned thereinz It will be seen therefore that the opposed parallel walls' of they cutawayl 35 et the barrer are positioned beneath the jogs 38 of the passage through the trigger guardv walls.- Then, after: positioning the trigger 28 theV complementary magazine-receiver member isplaced in position. It wil1 be seenthat the engagement* of the jogs with the edge wallsI of the barrer at its cutaway portion prevents the barrel from' rotating. relative tothe magazine receiver, and thus always insure that the opening 35 the loarrreiV faces vertically upwardly. The end* wall' sinfacesi of thel receiver', a's appears' in'- Fig. 2y are immediately inside of the barrel wall at the ends olf the cutaway 35A and hence the barrel is lfleldagainst longitudinal movement with respect to the said receiver.

With the' barrel and magazine receiver as*- sembled as above set forth, the` assembly is placed upon one of the halves of the stock so that the barrel occupies the semicircuiar groove therein, and the magazine receiver fits within the transverse pocket Ht. The other stock portion isY then placed in position, and is sec'lslred'` to the" previously placed stock memiblerl by' screws, gluing, or other meansl whereupon the' entire assembly is firmly held against displacem'e'rrtz,I within the stock.

The magazine 40 is'` desirably molded of plastic, and' has end walls which havearcuate-openings- 55, and` a wall thickness which permits the magazine to rest upon the walls of the barrel' i3 at the cutaway portion 3-5 thereof as shown in Fig. 3; The outside wally to wall length of thet magazine is very slightly greater: tha-rr the inner wall to' wall spacing of the' magazine Vreceiver so that the magazine i-sfrictionally held in. position.v

With no magazine in position in thev receiver, or with an unloaded magazine in position, it is' apparent thatY thev spring 4'8 wilt expand', pushing against the plunger 4-5 to move it along the barrel until the' end of the plunger fiange 4t strikes the vertical' 'end surface of the trigger nose 3'2. It is apparent that' ther rod 50 and head 5l thereon permit such free movement of. vthel spring and plunger. With the' maga-zine loaded,v asI with' the four simulated cartridges shown in Fig. 2 and placed in the socket above the magazine receiver, the" cooking piece t5 isv drawn rearwardly so' that the head 5| engages witlr the' rear end 52 of the plunger 45; whereupon the plunger may be drawn rearwardly and the spring compressed'.` As soon as the' end 465i ofthe plunger is suiiiciently withdrawn, the lowerrnost` projectile 33 will drop into the barrel chamber, the en@ ci thfeF projectile being in front of the nose of! the trigger.)` The: cooking piece I5 niay then be released so' that the end 46 of plunger' 45 abuis against the ope" posite end of the cartridge, the trigger nose restraining further movement. Cooking piece I5 is then pushed forwardly to its Fig. 2 position, and the gun is ready for firing. As the trigger is pulled and rotated clockwise in Fig. 2, the nose 32 disengagesfrom the endy of the cartridge and the reaction of the spring drives thev plunger 45 forwardly and propels the cartridge through the barrel. The loading operation of compressing the spring 48 and drawing the plunger 45 rearwardly to .permit a new cartridge to enter the chamber may be repeated and the gun fired until all projectiles in the magazine have been expended.l

Although the invention has been described by making' a fully detailed reference to a certain presently preferred embodiment, such detail of description is to be understood in an instructive rather than a limiting sense, many changes being possible within the scope of the claims hereto appended.
