FIG.4

INVENTOR ATTORNEYS United States atent CAP TAPE APPLYING DEVHCE Eiji Tada, Ichikawa-shi, Japan, assignor to Tada Manufacturing Co., Ltd., Tokyo, Japan Filed Apr. 8, 1965, Ser. No. 446,599 Claims priority, application Japan, Aug. 3, 1964, 39/ 61,210 3 Claims. (Cl. 42-57) The invention relates to a device for applying a cap tape to a toy gun and particularly to an automatic cap firing toy gun having a rotary feed drum serving as an anvil, with which a hammer is operatively associated.

An object of the invention is to provide a device which can readily and rapidly apply a cap tape to a roll-carrying pin and a rotary feed drum serving as an anvil by swinging a presser away following opening the cover of a cap tape chamber upon only operation of a catch pin projecting outward through a longitudinal slot provided on one side of a gun body.

Another object of the invention is to provide a device which can easily lock up the closed cover of a cap tape chamber by a sliding frame following holding a cap tape unrolled from a roll moderately against a rotary feed drum serving as an anvil upon only operation of a catch pin projecting outward from the sliding frame through a longitudinal slot provided on one side of a gun body.

The invention will be further described in connection with the accompanying drawings, in which:

FIG. 1 is a side elevational view of an automatic toy machine gun;

FIG. 2 is a front elevational view as viewed from the muzzle side of the same;

FIG. 3 is an enlarged perspective view of the interior of the gun body of the same;

FIG. 4 is a plan view of the same, partly in section;

FIG. 5 is an end view from the front side of the same, partly in section.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

Referring now to the drawings, the reference character 1 designates a gun body which supports a barrel 1a having a depending hand-grip 5 and houses operating mechanisms inside, being provided with a second handgrip 4 slantingly downward and connected with a stock 3 at the rear portion. A cap tape chamber 2, which has a cover 2a, in the shape of a quadratic prism and a power transmission housing 21) in the shape of a horizontal short cylinder depend down from the front portion of the gun body 1 on one side of which is provided with a longitudinal slot 1b in the rear position. The cover 2a having an aperture 20 for locking on the rear side wall is hingedly mounted by a pivot 2d on the both side walls of the cap tape chamber 2 to swing open.

Another spring-loaded cover 7 is hingedly mounted on the rear end portion of the gun body 1. The portion above mentioned has a sight 8 on the upper side and contains three pieces of dry cells 9 inside.

A trigger 6, of which the lower portion peeps out of an opening provided on the lower portion of the gun body 1 adjacent to the second hand-grip 4, is formed into a horizontal frame at the upper portion being housed in the gun body 1 and having a contactor 6a protruding upward at the rear end.

A U-sh'aped guided frame 10, on which is slidably mounted a U-shaped sliding frame 12, is fixed Within the gun body 1. An axle 11 fixed to the guide frame crossing the latter carrys pivotedly the trigger 6 so as to be swingable in two coincident rectangular openings 12b provided on the bottoms of the sliding frame 12 and the guide frame 10. The slots 12a provided on opposite sides of the sliding frame 12 and the rectangular opening 12b on the bottom of the same permits freely the sliding motion of the sliding frame 12. A catch pin 13, which have a knob 14 at the outer end, fixed to one of the opposite sides of the sliding frame 12 projects outward through a longitudinal slot 1b provided on one side of the gun body 1.

A pin 17 for carrying a roll of a cap tape 18 which is provided with perforations 18a at intervals spaced midway between the caps 18b, is fixed horizontally to the inside of the cap tape chamber 2. A rotary feed drum 19, which has small protuberances 19a around the peripheral surface at intervals spaced to fit into the perforation 18a, serving as an anvil is provided over the pin 17. A presser 20 for holding the cap tape 18 unrolled against the peripheral surface of the rotary feed drum 19 is pivoted swingably by a vertical pintle 21 to any adequate part in the vicinity of the rotary feed drum 19 within the cap tape chamber 2. The presser 20 is composed of the upper portion, which is curved in an arc and has an opening 20b, and the lower portion which is L-shaped and has a sleeve or a crosswise side wall 20a.

A rearward latch 15 to engage with the aperture 20 for locking the cover 2a of the cap tape chamber 2 and a downward plate-like pusher 16 to push the sleeve 20a for releasing the presser 20 are formed at the front end of the sliding frame 12.

A vertical small electric motor 22 mounted on the bottom of a fixed frame within the housing 2b drives the rotary feed drum 19 through a train of gearing (not shown) and at a time a cam (not shown) through another train of gearing (not shown). A hammer 23 pivoted swingably to any adequate frame within the housing 2b, opposing its striking end by an action of a strong coiled spring closely to the peripheral surface of the rotary feed drum 19 so as to strike any cap 18b of the cap tape 18 against the peripheral surface of the rotary feed drum 19 serving as an anvil and fire by a sudden drop of the striking end of the hammer 23 after the cam has bounced it up.

A coiled spring 25 usually restraining the trigger 6 is anchored with a vertical plate 24 projecting laterally from the inner side of the gun body 1.

A conductive plate 26 is arranged horizontally above the trigger 6 within the gun body 1 and equipped with a contact 26a on the underside, which corresponds to the contactor 6a of the trigger 6.

One pole of the dry cells 9 is connected by a lead a with the conductive plate 26 and another pole of different kind connected by a lead b with the metallic sliding frame 12 or the metallic guide frame 10 for grounding.

In operation of this embodiment, when the sliding frame 12 is slid forward by shifting the catch pin 13 forward along the longitudinal slot 1b provided on one side of the gun body 1 by means of the knob 14, the latch 15 at the front end of the sliding frame 12 is disengaged from the aperture 20 on the rear side wall of the cover 2a of the cap tape chamber 2 and the cover 2a is opened in the direction shown by the arrow in FIG. 4, swinging around the pivot 2:1 by its own weight or the spring action. Then, upon further shifting the catch pin 13 forward, the sliding frame 12 is also slid forward and the pusher 16 at the front end of the sliding frame 12 pushes the sleeve 20a of the presser 20 so that the presser 20 is swung around the pintle 21 as shown by the arrow in FIG. 4, resisting to the force of the spring wound around the pintle 21. Accordingly, a fresh roll of a cap tape 18 can be mounted readily and rapidly onto the pin 17. After the cap tape 18 unrolled from the roll on the pin 17 has been applied to the rotary feed drum 19, when the catch pin 13 is shifted backyard along the slot 1b by means of the knob 14,

a the pusher 16 of the sliding frame 12 separates from the sleeve 20a of the pressure 20 and causes the presser to swing back to its original position by the spring action so that the cap tape 18 is held moderately against the peripheral surface of the rotary feed drum 19 by the curved portion of the presser 20 and so that latch 15 at the front end of the sliding frame 12 can be engaged with the aperture 20 on the side wall of the cover 2a of the cap tape chamber 2 to lock up the cover 2a by shifting the catch pin 13 (backward) to its original position after closing of the cover 2a.
