Application August 26, 1942, Serial No. 456,245

4 Claims.

My invention relates to recording devices, and has among its objects and advantages the provision of an improved rifle target designed to regs ister hits on the target and to totalize the number of points made with a predetermined number of shots.

In the accompanying drawings: Figure 1 is a diagrammatic View of a target in accordance with my invention.

Figure 2 is a face View of the target. Figure 3 is a sectional view. Figure l is a rear face View of the target partly in section.

Figure 5 is a perspective view of a selenoid mechanism for actuating the counter mechanism.

Figure 6 is a sectional view of a target switch. In the embodiment of the invention selected for illustration, Figure 1 illustrates a base It provided with an upright standard I2 having a target I4 supported on its upper end. This target comprises a bullet proof panel I6 of relatively large diameter and fixedly secured to the standard I2. Target members I8, 20 and 22 of progressively smaller diameters are arranged concentrically of the panel I6 and with respect to one another.

The target member 22 is provided with a shaft 24 slidably mounted in openings 26 in the target members I8 and 20 and the panel I 8. Two shafts 28 are attached to the target member 28 and are slidably guided in openings 30 in the target member I8 and the panel I6. Two shafts 32 are also attached to the target member I8 and are slidably mounted in openings 34 in the panel I6.

A housing 36 is attached to the rear face of the panel I6, which housing includes a detachable wall 38 provided with openings 48' through which the shafts 24, 28 and 32 are slidably extended. Figure 3 illustrates the normal positions of the target members I8, 20 and 22 which positions are yieldingly maintained by reason of compression springs 42 mounted on the respective shafts 24, 28 and 32, with the springs abutting flanges 44 attached to the shafts and the wall 38.

All the shafts have tapered ends provided with tapered contacts 46. In Figure 6, the contact 46 on the shaft 24 is engageable with spring contacts 43 when the shaft is shifted against the tension of its spring 42, as when the target member 22 is hit. Wires 5!! are connected with the contacts 48.

In Figure 4, two wires 52 are respectively connected with spring contacts 54. Two companion contacts 56 are electrically connected by a lead 58. The two sets of contacts 54 and 56 are arranged for coaction with the tapered contacts 46 on the shafts 28.

Two wires 60 are electrically connected with spring contacts 62, and the companion contacts 64 are electrically connected by alead 66 The two sets of contacts 62 and 64 coact withthe tapered contacts 46 on the shafts 32. All the shafts are preferably of insulative material, while all the contacts 48, 54, 56, 62 and 64 are identical and mounted on the wall 38.

A counter or odometer 68 is mounted inside a housing Ill which may be located remotely from the target so that the reading thereon may be readily visible by those engaged in target practice. Insidethe housing I0 is mounted solenoids 1-2, 74' and 76 respectively electrically connected with the wires 50, 52 and 6H. Normally the solenoids are deenergized and are energized only when the respective target members 22, 20 and I8 are hit. The counter 68 may be of conventional construetion and need not be described in detail. Means for actuating the counter comprises a lever I8 mounted for closewise rotation independ ntly of a ratchet wheel 8%. Normally the lever I8 rests on a stop 62. COIlnterclochwise rotation of the lever I8 is consummated through energization of one of the solenoids, which rotation imparts rotary motion to the ratchet wheel 80 through the medium of a pawl 84 pivotally mounted on the lever. Armatures 86, 88 and 99 are associated with the respective solenoids I2, 74 and I6. Each armature includes an elongated loop 92 loosely receiving a pin 94 attached to the lever I8. Figure 5 illustrates the normal positions of the loops 92, with the pins 94 spaced progressively increasing distances from the axis of the lever I8. Thus upward movement of the armature 86, which is located closest to the axis of the lever I8 imparts the greatest rotary motion to the ratchet wheel 80, which rotary motion progressively decreases with respect to the action of the armatures 88 and 90. The lever I8 falls to the position of Figure 5 through its own weight.

One wire of each group 50, 52 and E8 is connected with a source of current 96. Each group of wires may be electrically connected with lamps 98 to indicate the target hit by a particular shot.

Figures '7, 8 and 9 illustrate a modified form of counter action, wherein the counter Iliil is provided with a lever H12 identical with the lever 78. Three links Hi4, I98 and I08 are operatively connected with the lever I82 through the medium of elongated loops I I0 loosely confining pins I I2 attached to the lever I82. A tension spring H4 yieldingly holds the lever I02 in its normal position of rest on a stop I I6.

Links I04, I06 and I08 are connected with levers H8, I20 and I22, respectively. These levers are pivotally connected with brackets I24 mounted on the floor I26 of a housing I28 corresponding to the housing I0. All the levers II8, I20 and I22 normally lie on shoulders I30 on latches I32 pivotally mounted on a shaft I34. The latches I32 are in the nature of armatures respectively actuated by solenoids I36 corresponding to the solenoids I2, I4 and I6. Each of the links I04, I06 and I08 is provided with a stop I36 engageable with its respective lever when pivoted upwardly. All the links have threaded shanks I38 extending loosely through eyes I40 in the respective levers, so that the levers may drop downwardly when released by the latches I32.

To the levers II8, I20 and I22 are pivotally connected segmental gears I42, as at I44, each gear having two gear sections I46. A relatively wide gear I48 is driven by a motor I50. When one of the armatures I36 is energized, the latch I32 associated therewith is attracted toward the armature for releasing the lever supported thereby, as the lever falls downwardly one of the gear sections I46 is brought into meshing engagement with the gear I48 and rotated in a clockwise direction. Rotation of this gear section imparts a lifting motion to the carrying lever for elevating its respective link and actuating the lever I02 to impart counting rotation to the ratchet wheel I52 associated with the counter I00. The links I04, I06 and I08 are arranged at progressively increased distances from the axis of the lever I02 to rotate the ratchet wheel I52 in variable amounts.

In both forms of the device, the smallest target member is operatively connected with the relay which advances the counter mechanism in the greatest amount, so that the total count registered by the counter will depend upon the skill of the shooter in hitting the target members registering the largest values.

Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
