EDWARD BAYNES BADCOGK, OF LONDON, ENGLAND.

TARGET.

To all whom it may concern:

Be it known that I, EDWARD BAYNEs BAD- COCK, subject of the King of Great Britain, residing at 7 Pembridge Crescent, London, England, have invented 1 a new and useful Improvement in Targets; and I do hereby declare the following. to be a full, clear, and exact description of the same.

My invention comprises improvements in and relating to targets, and refers to that class of such which are adapted for use with a cinematograph or othgr picture projecting device, and in which mechanism is provided whereby when a shot is firedthe motion of the cinematograph film is arrested leaving the picture stationary upon the target screen to enable the result of the shot to be ascertained; the object of the present invention being to provide a-simpler and more effective means for arresting the movement of plates are fiXed to a framework.

' According to this invention the movement of the cinematograph is arrested through the intermediary ,of vibrations set up by the impact of the bullet on any suitable part of the target apparatus, these vibrations being' adapted to break, make orinfluence a circuit controlling the movement of the cinematograph.

Referring to the drawings:Figure 1 of the drawings shows a portion of the vibrator and the contact device in side elevation,

and the screen and electric connections for stopping the picture projectingmachine more or less diagrammatically. Fig. 2 shows the vibrator frame in front elevation.

In one form of this invention, as illus trated upon the accompanying drawings, behind the perforable screen Iprovide anunperforable vibrator, as distinguished from a bodily movable member, which is vibrated when struck by the bullet, being adapted to make, break or influence a circuit con- Specification of Letters Patent.

Application filed July 11, 1914. Serial No. 850,488.

trolling the movement of the picture pro- The screen is preferably according to the prior Patent No. 1,027,371 and controlled accord ng to the prior Patent No. 1,075,894. The vibrator is preferably of substantially the same size as the screen, and it may conveniently consist of a metallic framework a having a bar or member 6 dividing it into two parts, this bar being say of T section and of'such rigidity that it will vibrate when influenced by the impact of the 1 bullet. Metal strips 0, preferably flat, are

secured between the frame and the vibrating 1 bar, the edges of these strips preferably overlapping, there being a sufiicient num her of strips to entirely fill the frame, and

thus provide a vibrator of a size substantially corresponding with thatof the screen. It will be seen from this that .when a shot strikes any one of the metal strips a vibration will be transmitted to the central bar or member I), which influences the contact controlling device. 7

The mechanism is preferably so arranged as to break a circuit when a shot-strikes the plate behind the target, and the contact device may conveniently consist of a spring controlled hammer cl, the one extremity (Z of the stalk of the hammer being anchored while the head d normally engages with an insulated contact 6 which is rigidly fixed to the back of the target. hammer is preferably in the form of a light spring having a part bent to a zig-zag form to give increased sensitivity, this form of spring also causing the hammer to make a movable or wipe contact with the fixed contact member thus avoiding risk of pitting at the point of contact. When the shot strikes the vibrator the hammer is caused to vibrate, thus opening the circuit which may directly arrest the movement of the cinematograph or may do so through the intermediary of other circuits.

As shown the anchor end of the hammer contact and the insulated contact e are connected to the primary of a transformer f the secondary of which controls a relay device g, of similar form to that described in the prior specification No. 1,075,894, the relay normally maintaining a circuit for energizing the magnet h; but as soon as the circuit is broken the solenoid z is energized and lifting the plunger restarts the cinematograph and actuates the screen j in similar manner to that described in the former specification N0; ,1;075,s94t.'

Or the hammer contact might be pivotally mounted, or it might influence other in termediate members to open the circuit. Or instead of a contact breaking device a contact making device might be employed, or there might be a permanent contact constructed after the manner of a microphone and arranged to vary the current in the circuit in order to control the cinematograph.
