(Cl. it-191)v 2 Claims. 1.

The present invention relates to sounding. mechanisms for toy guns and the like.

Principal objects of the invention are to provide. amechanism which will be compact, durable, and-inexpensive to make and assemble, which can be. incorporated in a toy such as a childs gun.

Theinvention provides a device comprising a. train of mechanism which can be actuated by a trigger to produce a sound which will simulate the firing of a gun and which may readily be incorporated in the breech of a toy gun or in any other toy structure where it is desirable to produce a clapping sound each time a trigger or the like is actuated.

An important object of the invention is to provide. a mechanism which will produce the desired sound each time the trigger or the like is actuated, so that the necessity of the operator performing some additional operation to cook the device is eliminated.

Another important object is concerned with providing for an adjustment of the parts so that the loudness of the sound can be regulated.

General objects are concerned with producing a toy gunwhich will be realistic in appearance andjcan be operated, in the manner of a semiautomatic firearm, to produce a simulatedreport each time the trigger is pulled.

With the foregoing and other objects in View, a preferred embodiment of the invention which has been found entirely satisfactory in actual practice'is'shown in the accompanying drawings, in which Eigurelisa side elevational view of a complete t'oy'gun embodying the invention;

Fig. 2is a similar view with the side cover plate removed to show the gun breach cavity and the sound-producing mechanism positioned therein;

Fig. 3 is aside elevational view, on an enlarged scale, of the gun breech portion, showing the parts of the sound-producingmechanism in the relation which they assume when the trigger is pulled toward firing position;

Fig; 4" is a similar View showing the relation of the parts at the instant of firing; and

Fig. 5 is a similar view showing the parts in the relation which they assume when returning to their normal; cocked position.

Referring'to the drawings, the reference numeral l designates'the breech portion of a toy gun haVing also a stock 2 and a barrel 3. The gun may be madein its entirety from a single block or separate pieces of wood; but of course any other suitable material may b'e'sub'stituted.

The breech portion I is hollowed out, or preferably. out completely through, to provide a cavity 4; which is permanently closed at one side surfaceof the breech portion (the rear side asseen inall the figures of the drawing) by an integral part of thebreech material or, preferab1y, by a permanently; fastened closure. plate of thin. plywood or the like. The shape of the cavity 4-is of: no particular consequence as long as it is capable of housing the working parts of the mecha-- nism and providing space for their respective movements. To this end therefore the cavity may be made in the irregular, special outlineshown in the drawings.

The elements immediately concerned with producing a sound responsive to pulling a trigger to fire the gun comprise a sounding anvil 5 and a striker 6 bestmade in the form of a metal button projecting from the forward end portion. of a hammer 1. The anvil is best made in the form of a thin strip of wood mounted in notches formed in the margins of the cavity 4- and bridging an openingB cut through the lower forward'portion' of the breechso that the sound produced [by impact of the striker on the rear surface of the anvil-willpass unobstructedly through the opening 8 and be heard clearly and without anymuffling.

The hammer 1 is a lever of the first order having aforward arm 9 which carries the striker 6 and having a rear arm l0. Both arms extend oppo' sitely from a fixed pivot pin ll set in a bearing; socket which does not appear in the drawing but which is formed in the base of the cavity 4. A hammer spring [2 acts under compression be-- tween the forward arm 9 of the hammer and the adjacent wall of the cavity 4 to urge the striker down against the anvil. It willbe obvious that if the hammer is rocked, clockwise as shown in the figures, and then released, the spring I12 acting in tension will cause the striker 6 to hit the anvil with all the force stored up in the spring [2- so as to produce a clapping sound or report.

The mechanism for operating the hammer comprises a rocker l3 mounted on a pivot pinl li which is-fixed in a bearing socket which doesnot. appear in the. drawing but which, like the bearing socket for the pivot pin I I, is formed in the baseof the cavity 4. This rocker has secured in or to it a trigger it projecting through a slot l6. (Fig. 3) in the lower portion of the gun breech and extending into a triggerguard IT. A rocker spring is is mounted under. compression between. the. rear side of the rocker and the back of the cavity 4, or a movable abutment l9 positioned. loosely therein for wobbling sufliciently tokeep the spring always directed more or less axially against the rocker. It will be obvious that the. relationship is such that the spring l8 tends to keep the rocker I3 rotated clockwise to the limit permitted by engagement of the trigger I5with the forward end of the slot it (and/or contact 1 s'hgwneatifldn Figs; 3 and 5,,to, provide a pair:

of spaced parallel ears 2| in which is pivoted, on a pin 22, a pawl or dog 23. This pawl is a lever of the first order and includes a forward arm 24 which is engageable with the rear arm 10 of the hammer 1 and includes also a rear arm 25 which is connected by a pawl spring 26 to the rocker. spring to the rear arm of the pawl and a screw 28 secures its other end to the rocker so that the spring is held under tension. The effect is to tend to rotate the pawl clockwise to the limit permitted by engagement of the screw .21 with the base of the slot 20, so as to project the forward arm 24 of the pawl into engagement with the rear arm of the hammer, but this projection of the pawl is yieldable, against the action of the spring 26. I

With the parts normally in the relation shown in Fig. 2, the striker 6 of hammer 1 will be held down against the anvil by the spring l2,the rocker [3 being held at the clockwise limit of its rotation by the spring l8, and the pawl 23 being held projected to its limit by the spring 26, with the forward arm 24 of the pawl overlying the rear arm In of the hammer. When the trigger is pulled rearwardly, as in Fig. 3, the pawl engages the hammer and rocks it clockwise to lift the striker from the anvil. fhis movement continues until the pawl slips past the rear arm of the hammer to release the hammer, as shown in Fig. 4, whereupon the action of the spring I2 drives the striker into quick engagement with the anvil, to produce a sound or report which is amplified by the sounding board effect of the cavity 4 and which issues through the opening 8.

' The parts are automatically restored to cocked position by release of the trigger. In this movement the spring is turns the rocker clockwise, the pawl is turned counterclockwise as it rubs against the rear arm IU of the hammer, tensioning'the spring 26, all as shown in Fig. 5, until the pawl finally slips past the hammer and the parts are restored to the relationship shown in Fig. 2.

It will be observed that the length of stroke of the hammer, and consequently the loudness of the report caused by the striker 6 hitting the anvil 5, can be varied by adjusting the distance to which the screw 27 projects from the pawl 23. With this screw turned fully down into the pawl, as shown in the figures, the pawl is permitted to project a maximum distance from the rocker, and the hammer swings through a maximum stroke to produce a comparatively loud sound. However, if a less loud sound is desired, the screw 21 can be turned out more or less so as to engage the bottom of the slot 20 in the rocker and reduce the permissible projection of the pawl, thus causing the pawl to slip past the rear arm of the hammer before the hammer has rocked through as great an'angle. This has the effect of reducing the length of the hammer stroke and correspondingly reducing the loudness of the re-.

port made when the striker impacts the anvil. I consider this an important feature of the invention because it permits the device to be tuned up or down. through a considerable range of loudness to suit varying conditions of use.

The cavity 4 and the train of mechanism contained in it are covered by a plate 29, shown in Fig. 1, which may be made in the form of a thin sheet of plywod which is removably held against the breech of the gun as by screws 39. Likethe back or bottom of the cavity 4, this plate\29 is provided with sockets 3| and 32 for beagring'the fixed pivot pins II and M of the hammer and 15 2.137.357

A screw 2! secures one end of this,

ency of the springs l2 and 18 to distort them or their positions.

The rocker, pawl, hammer, abutment l9, pivot pins, trigger guard and anvil, and even the trigger, may be made inexpensively of small pieces of wood such as scrap material from any hardwood fabricating plant. All these parts may be jigsawed by automatic machinery, and the gun body and metal parts can also be made at little cost. Assembly is obviously a simple matter requiring little labor and no special skill.

All the working elements may be made in stout and substantial proportions, and wear during operation is negligible so that the device is extremely durable and should last indefinitely.

It is to be noted that the operating mechanism is adapted to be installed in devices other than toy guns, wherever it is desired to make the production of a clapping sound responsive to the actuation of a trigger or analogous element.

It is believed that the foregoing description makes it clear that a structure producedin accordance with the principles of the invention attains all the objects and provides all the advantages first hereinabove set forth.

The mechanism is capable of being modified and altered within the spirit of the invention and within the scope of the broader of the appended claims.

I claim:

1. In a sounding mechanism for toy guns and the like, a. sounding anvil, a hammer rotatably mounted adjacent to the anvil, a rotatable rocker, a pawl mounted on the rocker for engaging the hammer to rotate the same away from the anvil, a spring for biasing the hammer into striking relation with the anvil to produce a sound, and means for varying the extent of projection of the pawl from the rocker to adjust the extent to which the hammer rotates away from the anvil and thereby regulate the loudness of the sound.

2. In a sounding mechanism for toy guns and the like, a sounding anvil, a hammer rotatably mounted adjacent to the anvil, a rotatable rocker member, a pawl member mounted on the rocker member for engaging the hammer to rotate the same away from the anvil, a spring connecting the pawl and the rocker members and urging the pawl member into projected position from the rocker member, a spring for biasing the hammer. into striking relation with the anvil to produce a sound, and a movable abutment element projecting from one of said members and engageable with the other member to adjust the extent to which the pawl member projects from the rocker.
