No. 586,279 Claims priority, application Japan, Oct. 23, 1965, 40/ 85,855 3 Claims. (CI. 42-57) ABSTRACT OF THE DISCLOSURE A toy machine gun having a trigger, which upon depression, rotates a sector gear that meshes and rotates a pinion fixed on a transversely movable shaft. When the trigger is depressed the shaft is positioned to mesh a gear thereon with a cam shaft which, through a suitable cam and gearing arrangement, drives a cap feed roller, a cap exploding hammer, and a flywheel. When the trigger is released, a spring returns it to a normal position wherein the gearing on the transversely movable shaft is disengaged from the gearing on the cam shaft. However the cam shaft continues to rotate through the action of the flywheel. Thus the cap feed roller, and hammer continue to operate after the trigger is released.
This invention relates to a hand-operated toy machine gun and more particularly to the type producing a succession of explosions from a cap tape by turning of a sector gear by hand operation against the force of a restraining spring in one direction so as to rotate a feed roller for feeding a cap tape to an anvil and a flywheel through a train of gearing including a pinion on a shifting shaft, which meshes with the sector gear and a pinion on the cam shaft to which is fitted a cam to actuate a hammer for striking the cap tape on the anvil or by turning of the sector gear by the recoiling force of the spring in another direction so that the flywheel continues to rotate the feed roll and to actuate the hammer through a train of gearing excluding the pinion on the shifting shaft.
An object of this invention is to provide a light-weight and economical toy machine gun, producing a succession of explosions, which does not require the use of a midget motor operating on a consumptive dry cell.
The invention will be further described in connection with the accompanying drawings, in which:
FIG. 1 is a side elevational view of a toy machine gun;
FIG. 2 is a perspective view of the same with its magazine cover opened;
FIG. 3 in a plan view of the interior of a gun body of the same, partly in section;
FIG. 4 is a side elevational view of the same;
FIG. 5 is an end view from the front side of the same;
FIG. 6 is a back side elevational View of the same in the state of a hammer being not actuated by a cam;
FIG. 7 is the same view partly omitted in the state of the hammer being actuated by the cam.
Similar reference characters designate corresponding parts throughout the several figures of the drawings.
Referring now to the drawings embodying the invention, and more particularly to FIGS. 1 and 2 thereof, the reference character 1 designates a gun body which supports a barrel 2 having a front hand-grip 3 and houses operating mechanisms, being provided with a rear handgrip 4.
A magazine or cap tape chamber 5 in the shape of a quadratic prism at the lower portion depends down from the front portion of the gun body 1 from which a trigger 7 projects downward. A pin 37 to bear a roll of a cap tape projects horizontally from the inner side wall of 10 crossing the frame 8, meshing with a pinion 14 ona shifting shaft 13 which is borne laterally by the slots 12 provided longitudinally on opposite sides of the frame 8 to be able to shift either frontward or rearward as Well as to rotate. The frame 8 bears a cam shaft 16 parallel to the shifting shaft 13 on which is mounted a gear 15 which is capable of meshing with a pinion 17 on the cam shaft 16. The trigger 7 is ordinarily kept in the position swung clockwise so as to separate the gear 15 from the pinion 17 by means of a spring 11 whose both ends are received by the trigger 7 and the frame 8 respectively. Another pinion 18 on the left end of the cam shaft 16 meshes with a crown gear 19 on the shaft 20 which carries a feed roller 21 for a cap tape a. A two-lobed cam 22 to actuate a hammer 25 is mounted between both the pinion 17 and 18 on the cam shaft 16.
As shown in FIGS. 6 and 7, the hammer 25, which is pivotly carried by an axle 23 and restrained by a spring 24, strikes a cap tape a on an anvil 26 to produce explosions when actuated by the cam 22.
As shown in FIG. 3, a gear 27 mounted on the right end of the cam shaft 16 meshes with a pinion 28 on 21 intermediate shaft; and a gear 29 fastened to the pinion 28 meshes with a pinion 30 fastened to a flywheel 31 so as to rotate the flywheel 31.
As shown in FIG. 5, a pressing roller 32 pairing with the feed roller 21 is rotatably carried by a swingable member 33 with a knob 36, which is pivotly mounted on an axle 34 fixed to the frame 8 and presses the pressing roller 32 against the feed roller 21 by means of a spring 35.
Accordingly, when the swingable member 33 is swung up with the pressing roller 32 by the knob 36 around the axle 34, the pressing roller 32 goes upward away from the feed roller 21 to able easily to insert the fore end of an unrolled cap tape between both rollers.
In operation of this embodiment, when the trigger 7 is pulled rearward after the cover 6 was opened and a roll of a cap tape a was applied to the pin 37 within the magazine 5, inserting the fore end of the cap tape a unrolled between the feed roller 21 and the pressing roller 32, the sector gear 9 turns anticlockwise against the restraining force of the spring 11 to rotate the pinion 14 whose shifting shaft 13 is kept to the front ends of the slots 12. This rotational motion is transmitted to the shaft 20 through a train of gearing which is composed of the gear 15, the pinion 17, another pinion 18 and the crown gear 19, to rotate the feed roller 21 for feeding the cap tape a to the anvil 26 while the cam 22 on the cam shaft 16 on which both the pinions 17 and 18 are mounted turns and actuates the hammer 25 which strikes the cap tape a on the anvil 26 to produce an explosion.
During this operation the rotation of the cam shaft 16 is transmitted to the pinion 30 through the gear 27 on the same cam shaft 16 and the pinion 28 and the gear 29 on the intermediate shaft to rotate the flywheel 31.
When the trigger 7 is released at the end of pulling, the sector gear 9 turns back clockwise by the recoiling force of the spring 11, dragging the shifting shaft 13 by engaging with the pinion 14 to the rear ends of the slots 12 to separate the gear 15 on the shifting shaft 13 from the pinion 17 on the cam shaft 16.
Thus, the cam shaft 16 continues to rotate, without the supply of the manual power through the inertia force of the flywheel 31 to produce explosions. Therefore, a
succession of explosions can be obtained simply by repetition of pulling and releasing of the trigger 7.
While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the claims appended hereto.
