Application filed November 12, 1915. Serial No. 61,145.

To all whom it may concem:

Be it known that I, WILLIAM SMITH, a subject of the King of Great Britain, residing at 29 Glengall road, OldKent Road, London, England, have invented new and useful Improvements in Apparatus for T arget-Practice, of which the following is a specification. I

My invention consists of an apparatus by means of which the direction of a rifle aimed at a picture shown upon a screen is indicated upon the screen by means of a beam of light which is projected upon the screen by the pulling of the rifle trigger.

In cases in which the picture screen moves means are provided for arresting the motion at'the time of pulling the trigger of the rifle.

The rifle is mounted upon a stand and the axis of the light projector is moved in harmony With the rifle. When the trigger is pulled the rifle is allowed to move but the light projector remains stationary.

The drawings illustrate one method of carrying out this invention.

Figures 1 and 2 show a side elevation and plan of the stand upon which the rifle is mounted. Fig. 3 is a side elevation of the light projector and Fig. 4 is an end elevation of the mechanism for stopping the movement of the picture screen.

1 is a rifle mounted in a fork 2 on pivots 3 which allow it to move in a vertical plane. The fork 2 is mounted in a pedestal 4 and is retained in the pedestal by means of a screw 1 5 but is free to rotate. Between the fork 2 is a frame 6 free to turn on pivots 7 and carrying a plunger 8. On the stem of the plunger 8 is a washer 9 which compresses a spring 10 coiled upon the stem of the plunger when it is moved from right to left as is shown in Figs. 1 and 2; the plunger is held in this position by means of one end of a catch 11 which engages with a collar 12 on the stem of the plunger. The catch is pivoted at 111 to an arm 13 secured to the frame 6. The other end of the catch 11 projects behind the trigger 14 of the rifle 1. The rifle 1 is connected to the frame 6 by a link 15. On the pedestal 4 is a cylinder 16 in which is free to turn another cylinder 17 to which is pivoted at 18 a yoke 19. On the yoke 19 is a cone 20 having a hole 21 at its apex. When the plunger 8 is moved from right to left the cone 20 serves as a guide thus insuring that the plunger 8 passes through the hole 21, by which means theframe 6 and the yoke 19 are locked together.

A connection 22 passes around a groove 171' in the cylinder 17 and thence over pulleys 172 and 173 to the light projecting mecharifle. Another connection 23 passes around a pulley 191 on the yoke 19 and thence over guide pulleys 192,193, down the center of the pedestal 4 to .the light projecting mechanism, whereby-any movement of the rifle in a vertical planeis communicated to this mechanism.

Referring to Fig. 3, 24 is a lamp and 25 a projector mounted upon a rod 26. The rod 26 is free to turn upon pivots 261 on a pedestal 27 mounted and free to turn upon a foot step 28. Upon the rod 26 is a pulley 262 around which the connection 23 passes. The other connection 22 passes over pulleys 281 on the foot step 28 and-around the while the collar 304 is pressed against the washer302 by means of a spring 31 coiled upon the shaft 29. By thus mounting the fly Wheel 30 a sudden jar to the mechanism is prevented when the machine is sud: denly stopped. The shaft 29 is driven through a clutch, one member 32 being freely mounted upon the shaft between the collars 303 and 305 fixed to the shaft. The other member 33 is secured to the shaft 29 by means of a key 331 passing through a slot 34 in the shaft 29. The member 33 is moved along the shaft in and out of gear with the other member 32 by means of a pivotedv lever35 which is actuated by means of an electro-magnet 36. On the lever 35 is an arm 351 which is moved, when it is desired to stop the film, into the path of a projec: tion 371 on a disk 37 mounted upon the shaft.

The conductors 361, 362 of the circuit of the electro-magnet 36 are led to the rifle 1 and so arranged that ,when the trigger is pulled the circuit through the electromagnet 36 is closed whereby the pivoted lever 35 is attracted and the member 33 of the clutch is disengaged from the member 32 while the arm 351 is moved into the path of the projection 371, thus stopping the picture film. WVhen the circuit is broken a spring 38 re stores the lever 35 to its earlier position.

In order to set the mechanism ready for use the stem of the plunger 8 is moved so as to pass through the hole 21 in the yoke 19 in. which it is retained by the catch 11. The rifle may now be aimed, all the movements of the rifle being communicated by means of the connections 22 and 23 to the light projecting mechanism.

When the trigger 14 is pulled the collar of the stem of the plunger 8 is released from the catch 11 and the plunger is withdrawn from the hole 21 by the action of the spring 10. The rifle is now free to move in any direction, but no movement is communicated to the light projecting mechanism. By the pulling of the trigger also the moving picture-has been stopped as above explained, and thebeam of light is projected upon that part of the picture at which the riflewas aimed.

What I claim is '1. In target apparatus, the combinationof a rifle, a mounting for the rifle made in two parts,'a coupling connecting the parts, means for actuating the coupling, a light projector, a mounting for the light projector, means for connectingthe light projector mounting with one part of the rifle mounting and a picture on which the light is projected.

2. In target apparatus, the combination -of a rifle, a mounting for the rifle made in" 'jector, means for connecting thelight pro jector mounting with one part of the rifle mounting, a moving picture and means for controlling the movement of the picture.

4. In target apparatus, the combination "of a rifle, a mounting for the rifle made in two parts, .a coupling connecting the parts, a trigger on the rifle which releases the coupling, a light projector, a mounting for the light projector, means for connecting the light projector mounting with one part of jector, a mounting for the light projector,

means for connecting the light projector mounting with the yoke and a picture on which the light is projected' 6. In target apparatus, the combination I of a rifle, a fork, p1vots on the fork for sup porting the rifle, a yoke, a coupling connecting the fork to the yoke, a trigger on the rifle which releases the coupling, a light projector, a mounting for the light pro ector, means for connecting the light projector mounting withthe yoke, a movingpicture and means for controlling the movement of the picture.

In target apparatus, the combination of a rifle, a mounting for the rifle made in two parts, a coupling connecting the parts, means for actuating the coupling, a light projector, a mounting for the light projector, means for connecting the light projector mounting with one part of the rifle mount- I ing, a moving picture, a shaft for driving the picture, a clutch upon the shaft and an electro-magnet actuating the clutch whose circuit is controlled by the trigger.

8. In target apparatus, the combination of a rifle, a fork, pivots on the fork-for supporting the rifle, a yoke, a coupling connecting the fork to the yoke, a trigger on the rifle. which releases the coupllng, a light projector, a mounting for the light projector, means for connecting the light projector mounting with the yoke, .a moving picture, a shaft for driving the picture, a clutch upon the shaft and an electro-magnet actuating the clutch whose circuit is controlled by the trigger.

9. In target apparatus, the-combination of a rifle, a mounting for the rifle made in two parts, a coupling connecting the parts, means for actuating the coupling, alight projector, a mounting for the llght pro-' jector, means for connecting the light projector mounting with one part of the rifle mounting, a moving picture, a shaft for drivlng the picture, a collar fixed to the shaft, another collar loose on the shaft, a
