TOY GUN INVENTOR. JOHN W GHR/S TUPHER United States Patent 'O l TOY -GUN .lohn W. Christopher, Columbus, Ohio Application April 2, 1952, Serial No.,2`80,037

11 Claims. (Cl. 116-228) My invention relates to a gun. It has to do, more particularly, with a gun which does not actually fire a projectile but in which the movement and discharge of a projectile is simulated andin which recoil and various sounds produced by an actual cartridge discharged from a gun are simulated. l

This application is a continuation-in-part ofrmy copending application, Serial No. 186,012, filed September 21, 1950, now abandoned.

In my said. copending application, I have disclosed a gun which is based on the phenomenon of persistence of vision and the Phi phenomenon. If a light of suicient intensity is flashed before the eyes at sufficiently close intervals, about sixteen flashes per second, the eyes will see a continuous light. This persistence of vision can be used in obtaining the appearance of movementfor which. there is no obvious physical stimulus. The .gun disclosed in said. application uses this principle to simulate the movement and discharge of a projectile with realism.

According. to m-y copending application, I provide a gun with a barrel which is translucent throughout its length or has translucent windows therein. In this barrelat longitudinal intervals I providesmallrbulbsorfilaments which are connected in a circuit with a source of current. In thistcircuit, I provide a `switch which, when. actuated, Will engage the bulbs or filaments along the barrel progressively and successively. The switch is actuated bythe trigger of the gun. The switch and the spacing Aof the bulbs or laments, as well as the intensity of the light produced by each bulb, are such that `the successive flashes will appear as a projectile moving-alongthe barrel tand being discharged from the outer end thereof.

According to the said copending application, I employ a battery in the light circuit as a source-of current. However, it is an object of the .present invention. to'gprovide a generating means in the gun for generating the necessary electric current upon actuation of the trigger thereof.

Another object of this present invention -is to'provide means in the gun for developing, upon the actuation of the trigger, realistic sounds simulating the firing of a projectile from the gun, the ricocheting of'a` projectile as if it leaves the gun and strikes an object, or various other sounds whichwill add to the realistic effect of the gun.

A further object of my invention is toprovide means inthe gun. for producing a recoil effect after thev trigger is actuated, thereby further adding to the realism of the gun.

The preferred embodiment of` my invention .is illustrated in the accompanying drawings. wherein similar characters of reference designate corresponding parts and wherein:

Figure 1 is a longitudinal sectional view through a gun made in accordance with my invention and having.V one type of sound producing means therein.

Figure 2 is an enlarged plan view, partly in section, of the barrel portion of the gun.

Figure 5 shows a modification where the gun'barrel is provided with a translucent window through which the light flashes can be seen.

Figure 6 shows another modification where the gun barrel is provided with spaced openings through which the light flashes can be seen. Y

Figure 7 is a detail in longitudinal section showing modified sound-producing means associated with the actuating mechanism of the gun.

With reference to the drawings, l have illustrated in Figures 1 and 2, one form which a gun may take according to my invention. The gun is, for example, in the form of a pistol and includes the body 10 which may be made entirely of plastic. The body includes the handle 11 and the barrel 12, the barrel preferably being sufficiently thin that it is translucent.

Spaced at intervals along the length of the barrel 3 are the small electric bulbs 13 which are carried by disks 14 that are removably screwed into openings in the barrel. Three of these bulbs 13 are shown but any number may be provided. A fourth bulb 15 is removably disposed in a reflector 16 disposed within the muzzle of the barrel. The bulbs 13 are adapted to create flashes of light visible through the barrel and the bulb 15 will be focused ahead of the muzzle at an imaginary target. shown in separate compartments formed by partitions 17 in the barrel, although this is not necessary. Other arrangements Amay be provided for obtaining spaced filaments along the barrel.

To create the effect of a projectile moving through and discharging from the barrel 12, the bulbs 13 and 1'5 must be energized successively and progressively towards the muzzle at short intervals. This is accomplished with the switch mechanism, indicated generally by the numeral 18, which is mounted within the body 16 of the gun.

The switch mechanism 18 is shown best in Figures l, 2 and 4. It includes a plurality of separate angularly Vdisposed `spring contacts 19 carried by the insulating posts 20 projecting from one side of the body 10 of the gun. Contact 21 is disposed on a metal disc 22 and is adapted to rotate with such disc. The disc 22 is keyed on a shaft 23 which projects from the opposite side of the body 10 towards posts 2i) and which is rotatably mounted on the body. The disc 22 is so located that when: it rotates the contact Z1 successively engages the contacts 19.

The discs 22 is rotated by means of a clock motor 24v which is disposed within the body 10 and drives the shaft This clock motor will be of the usual spring.- actuated type and the spring may be wound by means of a key 25 projecting outside the body of the gun. While the motor is being wound up by means of the key 25, the disc 22 will be prevented from rotating by means of the` hammer 26 of the trigger mechanism which is normally in ringposition (Figure l). The hammer is pivoted in a slot in the body 1t), a spiral spring 27 being associated with its pivot point to yieldingly hold its blunt forward end 23 in engagement with a hump or lug 29 formed on the periphery of disc 22. The key 25 will be turned. clockwise to wind up motor 24 and the disc 22 will normally not rotate in such direction. However, if the blunt end 28 of the hammer 26 is swung upwardly, the spring of motor 24 will be permitted to rotate the disc 22 clockwise.

Torelease disc 22 from hammer 26, the usual trigger 30Vv is provided. The trigger 30 is mounted on a pin 31 by means of a slot 32, the pin being carried by body 10. The upper end of trigger 30 ris notched at 3.3 and engages an ear 34 on the lower and forward end of hammer 2'6. Tension spring 35 is attached to the rear and upper end of trigger 30 and extends rearwardly to an Patented Feb. 14, 19563- The bulbs areanchoring pin 36 carried by the handle 11. This spring normally keeps the trigger 30 in the position shown in Figure 1. When the trigger 30 is pulled, the forward blunt end 28 of hammer 26 is moved upwardly, Vthereby releasing disc 22, until the notched portion 33 of the trigger slips off the ear 34 of the hammer, which allows the hammer then to be swung downwardly by means of spring 27, the spring 35 serving to return the trigger 30 to its original position. The disc 22, when released by the hammer 26, will be rotated in a clockwise direction until the lug 29 again strikes the end 2S, of the hammer, that is, through one complete revolution. When the lug 29 does strike the end 28 of the hammer, it strikes it with considerable force because of the spring action and this will produce a rearward movement of the body or a recoil action which will simulate the kick of a gun. The lug 29 serves as an eccentric off-balance weight to accentuate this recoil action but if desired the periphery of disc 22 at this point may be further weighted to increase this recoil action.

In the gun of the present invention, I provide means for generating current for the light bulbs or iilaments. This means comprises a generator 40 disposed within the handle 11. This generator is driven, when the disc 22 is rotated, by means of a shaft 41 which has a gear pinion 42 on its opposite end that engages a driving ring gear 43 carried by disc 22. Thus while disc 22 is rotated by unwinding of the spring of the clock motor 24 and the contacts to the lights 13 and 15 are successively engaged, the generator 40 is driven to generate current for such lights.

The electric circuit for connecting the generator 40, switch 18, and bulbs 13 and 15 is illustrated in Figure 4. The generator is provided with a ground 45 which may be connected to the metal body of the spring motor 24 (Figure 2). The other side of the generator connects to the individual lines 46 which run to the bulbs 13 and 15, the opposite ends of these lines being connected to the respective contacts and 21. The contact 21 is provided with ground 47 which in the gun is the disc 22 in which this contact is mounted.

Rotation of the disc 22 will be at such speed when the disc is released by the trigger mechanism that the bulbs 13 and 15 will be successively and progressively illuminated. This will create successive flashes which will give the impression of a projectile moving through the barrel and hitting the target'. The spacing of contact points 2t) and the speed of rotation of disc 22 should be such that the ashes occur at speeds just below that required to give the appearance of a continuous streak of light.

In Figure 5, I have illustrated a barrel 12a which is made of opaque material but has a translucent window 50 running its entire length. In Figure 6, the barrel 12b is of opaque material but has a series of longitudinally spaced apertures 50a through which the ashes are visible. Other arrangements may be provided for simulating the travel of the projectile.

It is desirable, in order to make the gun more realistic, to provide sound-producing means therein for producing various sounds, such as that of a projectile in an actual gun leaving the barrel, of a projectile striking a target and ricocheting, et cetera. I accomplish this in the manner shown in Figures l and 2 where it will be noted that a sound-producing cone 55 is mounted on the body 10 of the gun opposite to the side where motor 24 is disposed. This cone carries an inwardly projecting needle 56 which engages a sound-recording groove 57 that is formed in the inner surface of the disc 22. Obviously, this groove 57 may have recorded any sound it is desired to reproduce in the gun to make the gun more realistic. Thus, when the disc 22 is released to actuate the lights 13 and 15, the desired sounds are also produced.

In Figure 7, I illustrate a gun which is exactly like that shown in Figure l in the light-producing means but which has a different arrangement for producing sounds. In

this instance, the sound is produced by the lug 29a on disc 23a first striking a sound-making comb SSb and then striking a tuning fork 55a disposed at successive angular positions around the disc 22. These sound-producing members may be suitably mounted on the body of the gun. The member 5517 may be tuned, for example, to give a sound of a projectile passing from the gun barrel while the member 55a, for example, may give the sound of a bullet ricocheting after striking a target. Other sounds may be produced if desired.

It will be apparent from the above that I have provided a gun in which the discharge of a projectile is simulated both in light and sound. The current for the light is developed in the gun by a generator which is driven by the same clock motor that drives the rotatable switch or circuit-closing means. Thus, the gun is extremely simple and inexpensive and it is not necessary to replace batteries.

Various other advantages will be apparent.
