12 Claims.

My invention relates to an improvement in electric target rifles of the type employed with structures having photo-sensitive targets.

One purpose is the provision of a gun adapted to shoot a brief flash of light.

Another purpose is the provision of a gun in which an electric light source is employed which is masked by a shutter.

Another purpose is the provision of improved means for actuating the masking shutter of such a gun.

Other purposes will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings wherein:

Figure 1 is a perspective view of the device as a whole;

Figure 2 is a longitudinal vertical section through a portion of the gun mechanism;

Figure 3 is a similar section with the parts in different position;

Figure 4 is a section on the line 4-4 of Figure 2; and

Figure 5 is a section on the line 5--5 of Figure 2.

Like symbols indicate like parts throughout the specication and drawings.

Referring first to Figure 1, A generally indicates the target housing or cabinet; B indicates the firing stand; and C indicates generally the gun structure. It will be understood that any suitable conductive connections are employed, which extend between the cabinet and the firing stand and the gun. It will be understood that these Various connections are carried in flexible conduits or cables, one such cable D connecting the cabinet A with the gun stand B, and a second E, connecting the gun stand B and the gun C.

Referring to the operative parts of 'the device, and considering first the cabinet structure, generally indicated as at A, I illustrate an outer housing I, details of which do not form part of the present invention. It will be understood, however, that either an open space or a transparent window 2 is employed. To the rear of this window is any suitable scenic foreground indicated as 3, an upper portion of which is generally arcuate to conform to the path of the target structures below described. I6 indicates any suitable target drop, apertured as at I8, any suitable photosensitive member being positioned behind the aperture.

It will be understood that in the operation of the device, the aperture I8 is generally horizontally alined with a photo-sensitive member whereby the user, employing a light projecting gun, can sight through the aperture I8 and hit the said member with a flash of light.

Referring to the gun structure as shown in Figures 2 to 5, I may employ any suitable gun stock generally indicated as having a barrel 5I and sights 52. Mounted in the barrel, preferably at the rear end thereof, is an incandescent lamp 53. In circuit with the lamp is a mercury controlled switch generally indicated as 54. Any suitable lens or lenses may be employed to direct a relatively restricted light beam from the gun. I illustrate only one, but more may be employed if necessary. 56 illustrates a trigger pivoted as at 51 and having an inward extension 58 within the gun. Pivoted to this inward extension is a stem 59 passing through a bearing 68 which is apertured as at 6I to permit tilting as well as longitudinal movement of the stem 59 in relation thereto. 62 is a head or knob of insulating material at the inner end of the rod 59. Pivoted as at 63 to the member 58 is the dog 64 which is normally held in raised position as by the spring 65, which causes the end piece 66 to rest against an opposed abutment face 61 of the member 64. In other Words, in relation to its position in Figure 3, it can tilt in only one direction, namely in clockwise direction.

Connecting the member 58 with the gun stock, I illustrate a spring 68, secured at one end to an abutment 89 and secured at the other end to the member 58. As a matter of convenience it is shown as secured eccentrically with the member 64, although this is not ordinarily necessary.

Positioned above the trigger structure thus described and mounted between two bearing members 'III and 'II, is a longitudinally movable stern or rod 'I2 provided with a cone-shaped portion I3 intermediate its ends. Its outer end passes through a bearing bracket 'Id which is provided with an elongated slot 15, to permit tilting of the member 'I2 between the full and dotted line positions of Figure 3. A spring 'I6 tends normally to return the member 'l2 to the full line position in which it is shown in Figure 2, against a stop TI, shown in that gure. With it may be associated, for example, any suitable supporting bracket I8 upon which the pins or members IIJ, 'II are mounted. The spring 'I6 is secured at its opposite end, as at 19, at a point above the axis of the member 12, whereby it tends to move it into generally horizontal position, for example, the full line position in which it is shown in Figure 3.

A xed pin or abutment may, if necessary, also be employed, and is shown for example in Figures 2, 3 and 5. It may be employed to cause the member 12 to tilt upwardly into the dotted line position in which it is shown in Figure 3, in response to movement of the member 12 to the right, referring to the position of the parts in which they are shown in Figure 3. This is to clear the member 13 from the dog 64 at a predetermined point in the forward movement of the member 12 whereby it is released from the dog and can be snapped back into its initial position by the spring 16.

Pivoted in the aperture 85 in the bottom of the barrel, which may be formed by bending out portions of the barrel as at 86, is a shutter 81. Its pivot is indicated as at 88. Any suitable coil spring 89 is employed, and in Figure 4 one is shown at each side of the shutter, for moving the shutter normally into the closed position in which it is shown in Figure 2. Associated with the shutter is a trip member 99 also pivoted at 88. It is in engagement at one end, as at 9|, with the upper side of the shutter 31. The lower end 92 projects downwardly through the aperture in the barrel Ainto alinernent with the member 13'. A spring 93 tends normally to hold it in engagement with the shutter 61 but the spring 93 is of insufficient force to resist the coil spring 89.

It will be understood that when the parts are in the position in which they are sho-wn in Figure 2, the light source is masked by the shutter 81. When the riile is in generally horizontal position, the mercury switch 54 is adapted to close the actuating circuit for the lamp 53, the details of which circuit will later be described. Then, when the operator pulls the trigger 56, one result is to thrust the member 12 forward, in response to the engagement between it and the dog 64, as shown in Figure 2. As the thrust continues, in response to the rotation of the trigger in the normal trigger pull, the member engages the cone 13 and tilts the right hand end of the member 12 upwardly, permitting the dog 64 to clear it. 'I'his permits the spring 16 to draw the member 12 back to its initial position against the stop 11.

In the forward movement of the member 12, the upper portion of the cone 13 engages the lower end 92 of the member 80 and swings it about the pivot 88, without disturbing the position of the shutter 81. After the lower end 92 has cleared the cone 13, the spring 93 returns the trip member 9|] to its normal position illustrated in Figure 2. After the cone 13 is released from the member 92, and when the spring 16 draws the member 12 back, after it has cleared the dog 64, the upper edge of the cone then strikes the opposite side of the lower edge 92 of the member 99 and moves the shutter 81 into the open position in which it is shown in Figure 3. It keeps this position only for an instant, because the member 13 promptly clears the lower edge of the member 92, and permits the shutter 81 to snap quickly back into position in response to the movement of the springs 89. Thereafter the spring 68 returns the trigger to its initial position and the dog 64 clears the lower edge of the cone 13 and resumes the position in which it is shown in Figure 2, in response to action of the spring 65, and the parts are ready for the next trigger pull.

The trigger pull has an additional function, namely that of closing the gun switch which includes the opposed switch spring contacts |80 and |00a. This result is obtained by the engagement of the knob 62 with the outer @mi Of the leaf |00, as shown in Figure 3, the knob 62 being of insulating material. The switch contact leaves |00 and Ilma` are mounted in any block of suitable insulating material Iill, mounted in the gun stock as shown in Figures 2 and 3.

Note that all the movable parts above described, except the shutter structure, are mounted on a single removable plate |02. I illustrate an upstanding base portion |93 as shown in Figure 4. The parts |92 and |93 can be bodily and unitarily removed from the gun stock forrepair or inspection.

It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to the precise showing.

Taking my invention broadly, I have invented a gun for shooting a flash of light which is ei'ective for use for example with photo-sensitive targets, one of which is diagrammatically shown in Figure 1 The result of a trigger pull is to cause the shutter 81 or its equivalent to be moved very briefly from the masking position in which it is shown for example in Figure 2. When it is moved the light source 53 directs a beam outwardly along the gun barrel, for example through the lens 55. The parts are preferably so set and timed that the flash of light thus permitted is practically instantaneous and of such short duration as to prevent correction of aim on the part of the operator after the trigger has been pulled. A further function of the trigger pull is the closing of the trigger switch |09, Mla, which may have a function in connection with the operation of the device as where, in a coin operated machine, a limited number of trigger pulls may be permitted f-or the insertion oi a single coin. However, since such circuit and control does not of itself form part of the present invention it is not here indicated in detail.
