' MOTION-PICTURE \AND TARGET APPARATUS.

Application filed May 20, 1919, Serial No. 298,406; Renewed December 1, 1920, Serial No. 427,857. Original No. 1,889,877, dated September 6, 1921. Application for reissue filed May 28, 1927. Serial My invention relates to improvements in motion picture machines, and also to motion pictureftarget apparatus of the class employinga target, a picture pro ccting device, and electrical connections between the target and the projector actuated by the impact of a bullet on projectile on the target for automatically stopping the movement of the'picture film. d

In the employment of motion picture machines it is desirable at times to present a still picture on the screen insteadof a moving picture, thus, for example, where the moving picture is being utilized 1n connection with a lecture or a talk,-or, more fre' quently, when the motion picture machine is employed in connection wlth a target apparatus wherein the projectingdevice is flopped by means actuated by the impact z' of'a bullet orby firing a shot, etc;

Prior tomy invention, the stoppage of the picture 61m in order to produce the still picturehas beenaccomplis'hed by stopping all ofthe moving parts of the machine, the

result. being that the machine-soon becomes destroyed or inefficient, due to the sudden.

4 stoppage of its rapidly moving parts.

An object of the present invention is to provide simple and etlicient means for stopping the movement of a picture film for the purposes above described, without affecting or stopping the rapidly moving parts of the machine.

A further object of my invention 15 to provide a new ,and improved motion picture target apparatus.

moving picture machine, B a perforable screen onto which the pictures are designed to be projected;and C a target or back wall.

The moving picture machine, as illus- Referring to the drawings, A designates a trated, includes a casing 1, of any suitable construction, the lens 2, and a shutter 3. As shown, the movable parts are driven by means of an electric motor 4, although the machine may be operated manually. main drive shaft 5 is connected with the motor by means ofa belt 6 and drive wheel 7. 8 designates a fly wheel mounted on shaft 5. The film tape 9 is designed to be fed down through the machine from reel 10, over opening 11 of frame 12, in the usual manner. w

The film passes over and is fed through the machine by the feed wheels .or sprockets 13 mounted on a shaft 14, and' the usual in' termitten-tly driven wheels or' sprockets 15, the latter being mounted on shaft 16. Shaft 14 is driven from the main drive shaft 5 throughgearing' 17 and 18, and the shaft 16 is also driven from shaft 5. The means illustrated for driving the intermittently driven shaft 16 include a star wheel 19, of the Geneva type, mounted on and keyed to the shaft 16, a shiftable sleeve element 20 carrying a pin 21 and' having a clearancev space 22 for the star wheel and a groove 23,

said element 20 being mounted and slidable on drive shaft 5. The shutter 3, as illustrated, is driven from shaft 5 by means of gearing 24.

The elements above described, with the exception of the shiftable sleeve element 20, are of known construction and are arranged to operate a motion picture machine in the usual manner. It should also be understood that my invention'is not limited to the combination of these elements with means for arresting themovement of the film without The- * stopping the motor and the rapidlydmov mg parts of'the machine, for my invention I may be embodied in motion picture machines from. that shown.

having mechanism difi'ering considerably A characteristic and important feature of my invention is the provision-f means cooperating with the intermittently driven film feed wheel or sprocket,- or said wheel or sprocket and the other film feed wheel or sprocket of a moton picture machine, whereby the'movement of the filmthrough the machine may be stopped for a desired riod' of time without stopping or afi'ect- 1n the other movable parts of the machine. e mechanismemployed for sto ping therotation of the intermittently (ii-wen shaft 16, orthe feed wheels or sprockets 13, in addition to the element 20, includes a movable bent downwardly extending arm 25, pivotally secured ltO the framework of the machine with its fulci um point at 26.

nates a stop Arm carries a pin 27, the latter being enteredin the groove 23 of element 20. The

lower portion of the arm is bent, as shownat 28, and said portion 28 is formed with a flangev or bent up portion 29. 30 desigelement-mounted on shaft 5, the function of which is 'to'prevent an inward movementjof arm 25, and the 'consequent shifting of element 20 until the desired instant. That is to say, the .element 20- should be permitted to shde only when a complete picture is shown on the screen. Said'stop element 30 is formed with a collar 31 having a' laterally extending slot 32 throughwhich the flange 29' of arm' 25 may pass to permit the inward movement of said arm and element 20. The movement of arm ,25- is eifected by a horizontally extending having .one end attached to arm 25 i at 34 and its opposite end connected with a clutch, and a link 35, the latter being'pivotally secured to a portion of the frame.

As 'llustrated and as preferred, the move ment of the rod 33 is efiected by means of a bar 36 connected with and ada ted .to be moved by the core 37 of a solenoid 38 and .for this purpose, 'bar 36 is provided with a in 39 entered in the pivotally mounted .lin

means. i

For the purpose ofstopping' the rotation of the feed sprockets 13 on shaft 14, when desired, I provide a.clutch mechanism'40.

Said clutch mechanism, as shown, is operated by. means of. the bar- 36, a pivotallysupported link 41 secured at 42 to the frame, a rod 43 extending from the link to the pin 4-4 on bar 36 cooperating with the link.

The parts just described are articularly illustrated in the detail view of ig. 3, and,

35. It is evident, however, thatfbar 36 may be moved by otherthan electrical as there shown, are arranged to drive the film feed wheels. An upward movement of the bar 36 will release the clutch mechanism and also shift the slidableelement 20, thereby throwing pin-21 free of the star wheel 19 as the formerrevolves with the element 20. A movement of the bar 36 in the opposite-direction or into the position shown by Fig. 3 will permit the film to be fed through the machine, with the usual interm ittent movement.

The mechanism herein described provides simple and eflicientmeans for automatically stopping for a predetermined period .the movement of the film, thereby enabling a still picture to be shown on the screen, this a being accomplished, without stopping the other movable parts of the motion picture machine. 1 1

In the present invention I have shown the motionpicture machine and the above described means for stopping the picture film in connection with a target apparatus and electrically operated means between the target and the machine dcsignedto be oper ated by the impact of ,a bullet or projectile on the. target.

Tl ic ta'rget structure 45 is similar to the target structure shown in a patent issued to ie-November 27, I923. No. 1,475,493. As-

' Bars also carry a vertical'row of plates 51 having divided ends adapted to straddle a vertically movable switch actuating rod- 52. Rod 52 is provided'with a series of ins .53 which engage the divided ends of p ates 51.

It will be understood that an inward movement of an impact .plate' will 'tilt a bar 50, and that, when this occurs, the switch actuating rod 52 will be raised. Raising the rod'is designed to complete an electric circuit for the purpose of effecting certain operations hereinafter described.

In the-embodiment of rn'y'invention as shownby the drawings, rent employed inconnection withthe various parts of the apparatusis obtained from the main line 60. i .t

Arm is fulcrumedint'fidland has its cup-H per end attached to a slotted and horizontally. extending-arm 67.- v a The elements just described constitute a portion of an electrical switch device and timing apparatus, said switch and timing apparatus forming the subject of United States Letters-Patent No. 1,503,834, issued to me August 5, 1924. f V

As'shown herein, 68 designates a fixed contact strip of the switch mechanism and 70 a move le switch arm. des' ned to be thrown by the movement of the orizontally movablearm 67. The connection between the arm 67 and the switch. arm 70 includes a pivotally mounted arm 71 securedat 72 to the frame of the machine and pivotally' connected with arm 67 by a pin 73. Arm 71 at its upper end is provided with a pin 74 adapted to operate in a slot 75 of the switch arm 70. 'As shown, a movementof bar 67 to the left' will cause switch arm-70 ting an electric circuit to solenoid 38 of the motion picture machine, and at the same time completing an electric circuit to a motor 76 of the timing mechanism.

The timing mechanism includes. in addition to the motor, motor shaft 77, having a worm 78 thereon, a pinion wheel 7 9 meshing with said ,worm, a striking pin 80 carried on the pinion, a pivoted arm 81 having its ends divided and engaging a pin passed through arm 67, and a pivotally mountcd 1 arm 82 secured to the divided arm 81.

It will be understood that the closing of the circuit leading to solenoid 38 enerf gizesthc core 37 of the said solenoid to raise Q the bar 36, thereby throwing out the clutch mechanism 40 an moving the slidableelement 20 on drive shaft 5 to disconnect said element from theflstar wheel carried on the intermittently drivenshaft 16, thus stopping the film feed wheels 13 and 15, The time the movement of the film is arrested depends upon the speed of rotation of the wheel 79; It will be understood that, with the closing of the circuit 90 to the solenoid 3 8, a circuit pin 80 to make a revolution, for it will be noted that, upon each revolution of striking pin 80, said pin will come into contact with red 82, thereby causing the switch arm 70 to be brought from engagement with contact block 69 to contact point The speed of the mot-or is controlled by point 68 into engagement with stop block 69. V Forthe purpose of moving the screen or cuttainB, I provide a solenoid 93, the core '94 of which is employed for'movin'g a dog on a ratchet wheel 96-mou-nted on the shaft of the screen reel. The circuit 97 for solenoid 93 is also made and bro ken by means of the striking pin 80 on pinion 79.

'This is effected by employing apivotaliy mounted switch arin 98 adapted to be moved into contactflwith contact plate 99. y

100 designatesa movable shutter, preferably made o'fcolored mica,-this shutter being adapted "to be moved over and away from the opening 11 (see Fig. 1) by the movement of the 36 and the connections between said bar andshut-ter. Said connections includea toggle a'rm 101 carrying a in 102, a. pivotally mounted plate 103, the atter having a slotted portion 104 into which the pin 102 is'entered. The function of the shutter 100 is to change the color of v the picture thrown onto the screen during the time the movement of the film is arrested. It will be understood that the shutter maybe omittedif desired, although I,

,find it of advantage for the purpose of enn-g.-

bling the bullet holes made in the screen B move the slidable element on the drive shaft 5 to stop the movement of the film wheels 13 and 15', as above described.
