DETONATING DEVICE.

Application led October 24, 1921, Serial No. 509,790. Renewed July 5, 1928.

rlhis invention relates to toy detonating devices of the type adapted to explode successively a plurality of caps arranged, preferably, in a continuous strip.

An object of the invention is to provide a device in which the caps may be arranged in a magazine adapted to be advanced through the firearm so that the usual hammer may engage the caps successively.

Another object of the invention is to provide a magazine in which a strip of caps may be readily inserted for use in a pistol or other type of firearm.

A still further object of the invention is to afford a structure which is simple and inexpensive to manufacture, efficient and positive in its operation, and in which the explosions take place entirely within a casing without danger to the operator.

Further and more specific objects of the invention reside in the details of construction and in the combination and arrangement of the several parts, which will become more clear as the description proceeds.

In the accompanying drawings I have shown the invention as embodied in a toy pistol, although it should be understood that the invention might be applied to other types of firearms and might be considerably varied from the illustrative details of construction shown in the drawings and hereinafter described.

Fig. 10 is a cross section on the line 10-10 of Figure 9, and

Fig. 11 is an elevational view of a modified magazine construction.

Referring to the drawings for a more detailed description, the pistol comprises a case or shell shaped to form a barrel 10 and a handle or stock 11 to resemble a revolver. The shell is, preferably, cast or stamped and formed in two sections 12, 13, held together by bolts or screws 13. The section 12 has a marginal flange 14 which meets the inner face of the section 13 and maintains the two sections spaced apart. The barrel is open at its forward end, as indicated .at 15, (Fig. 4) and the rear end of the pistol is provided with a magazine inlet opening 16 so that a magazine 17 may be inserted in the barrel and fed therethrough by a mechanism later to be described.

A trigger plate 18 (Figs. 2 and 8) is mounted within the casing for reciprocatory movement; and has a forwardly extending portion 19 and a trigger 20. The plate is supported upon the inner face of the casing section 13 by means of a guide rib 21 (Fig. 7) upon the casing section which fits between two spaced guides 22 upon the inner face of the trigger plate. The trigger plate is held in its forward position, shown in Figures 2 and 3, by means of a coil spring 23 anchored at one end, 24, to the casing section 13, and at its other end, 25, to the trigger plate, a stop pin 26 upon the casing section extending through a slot 27 in the trigger plate and limiting its reciprocatory motions in oppo-site directions.

A hammer 28 is mounted upon the trigger plate and has its forked shank 29 extending beneath a strap 30 upon the trigger plate and bent upwardly to prevent withdrawal ofthe trigger from the anchoring strap. The strap fits loosely about the end of the hammer so as to permit the latter to be raised as the trigger plate is moved rearwardly as indicated in Figure 4. A leaf spring 31 having its rear end 32 fixedly secured in a lug 33 upon the trigger plate extends forwardly above the hammer and is fixedly secured to the hammer as indicated at 34:. This spring serves to maintain the striker portion 35 of lil the hammer projecting through an opening 36 in the forwardly extending portion 19 of the trigger plate and, as the hammer is moved rearwardly by the magazine during the retract-ion of the trigger plate t-he saring is flexed, all of which is clearly shown in Figure l.

Referring to the magazine which serves to raise the hammer as the trigger plate is retracted, it is preferable that the magazine be constructed so as to receive a plurality of caps arranged in strip form. The magazine comprises a face plate 37 having a plurality of openings 38 and arranged adjacent each opening an outwardly and rearwardly inclined tooth 3) which positioned in advance of the opening. The magazine is also formed with a back plate et) slightly spaced between the ends of the magazine from the face plate so as to form a chamber to receive a strip of caps positioned within the chamber with a cap registering with each opening. The lower edge of the magazine is provided with a series of shoulders el which provide an edge of rack formation, each shoulder being positioned beneath a cap opening. A spring stop or pawl .l2 is fixed in the forward edge of the guide rib 2l; and extends upwardly and forwardly so that its free end may successively engage the shoulders 41 as the magazine is fed through the barrel.

ln using this device the magazine is lirst loaded with a strip of caps, a dctonating cap being located in registry with each opening in the magazine face plate. The magazine is then inserted in the rear barrel opening 16 until its forward edge comes into engagement with the striker portion 35 of the hammer. The trigger plate and hammer are then retracted by means of the trigger and during this movement the striker is moved outwardly, as shown in Figure 3, by the lirst tooth 39 upon the magazine. As the retraction of the trigger is completed the striker moves past the end of the tooth and is forcibly thrown against the cap in the first magazine opening to explode the cap. During the retraction of the trigger plate and hammer the coil spring 23 has been extended and immediately upon the release of the trigger the spring serves to return the trigger plate and hammer to the position shown in Figure 2. During the return movement of the hammer and trigger plate the striker 35 engages the rear edge of the tooth positioned in advance of the cap which has been exploded and advances the magazine one step through the barrel until the spring pawl 42, which holds the magazine stationary during the retraction of the trigger plate, engages the next shoulder 41 upon the lower edge of the maga.- zine.

The above described operation may be con tinued successively until the caps within the magazine are exploded, whereupon the magazine may be withdrawn through the forward opening 15 in the barrel and relilled.

t will be observed that all of the explosions take place within the casing which is entirely closed at the explosion point, and thus no sparks or other flying particles from the caps can leave the casing.

Particular attention is called to the extreme simplicity of the struc-ture above set forth, it bein g observed that the hammer and its opern ating spring are mounted entirely upon the trigger plate and may be assembled therewith before insertion of the same within the casing. lt will also be noted that the hammer itself serves as the feeding means for the magazine, thus eliminating the' necessity for sepa ate feeding mechanism generally employed in toy pistols in which it is possible to explode a plurality of caps in quick succession.

leferring to Figures 9, 10 and 11, there is shown a modified embodiment of the invention in which the principle of operation is the same as in the pistol above described, but in which the mechanical construction is materially simpler, permitting production at considerably less expense. The pistol comprises a casing- 43 having a barrel portion all and a stock or grip portion 45, the casing being preferably formed from sheet metal; and may be suitably stamped out and bent from a single piece. rlhe casing encloses a trigger plate lo carrying the trigger 417; and the trigger plate is held within the casing, as by means of a bolt 48 passing through the stock of the casing below the trigger plate. rllhe trigger plate is formed from two strips of metal (Figure 10) suit-ably bent along a longitudinal line below their upper edges, as indicated at 49, to form a magazine chamber 50 adapted to receive the magazine 51. The two strips of metal forming the trigger plate may be held together by a clip 52 at the rear of the trigger provided with a stop 53 adapted to engage the casing when the trigger plate is moved forwardly, to prevent displacement of the trigger plate during the operation of the pistol. A hammer 5a having its head extending through an opening 55 in one wall of the magazine chamber and a spring shank 56 is held upon the trigger plate by means of clips 57 struck up from the trigger plate. At its forward end the trigger plate is surrounded by a tubular metal clip 5S which has a portion cut away to permit the same to be slipped over the forward end of the magazine chamber. This clip serves as a bearing for the trigger plate as it is reciprocated within the casing, since it has a comparatively tight lit within the barrel 44; and also assists the clip 52 in holding together the strips comprising the trigger plate. The magazine 51 has the openings 38 and the hammer engaging teeth 39 in advance of each opening just as the magazine 17 shovvn in Figure 7. It Will be noted, however, that shoulders 4l are provided along the upper edge of the magazine so as to engage successively a spring holding-paivl 60 mounted Within the barrel of the casing and held therein by a clip 6l struck out of the casing.

A strip of caps is placed upon the magazine with the caps registering with the openings 38 and the curved edge portions 5l of the magazine engaging' the margin of the strip of caps and holding it in position. The

magazine is inserted in the chamber 50' through its open rear end and the trigger plate is then reciprocated forwardly and rearwardly in the casing to advance the magazine through the chamber and explode the caps. As the trigger plate is moved rearwardly, the hammer head engages a projection 39 upon the magazine and is raised, the magazine being held stationary by the retaining pawl which engages a shoulder il upon the magazine. Continued movement ot' the trigger plate results in the hammer head striking the cap registering with the opening at the rear of the projection and eX- ploding the cap. Upon subsequent forward movement of the trigger' plate, the hammer head engages the projection which it has previously passed over and carries the magazine forwardly with the trigger plate. Continued repetition of the above movements causes successive explosions of the caps in the magazine and a feeding movement of the magazine through the chamber and barrel until the caps have all been exploded, Whereupon the magazine may be Withdrawn from the open forward end of the chamber to be refilled.

lt should be understood that numerous modifications may be made in the illustrated and described structure Without departing from the range of the invention.
