Description
Feb. 9, 1937. 'c. H. coATEs APPARATUS FOR TRAINING IN GUNFIRE Filed NOV. 25, 1935 lnventmr Charles H- Enates Atturne Patented F ch. 9, 1937 UNITED 3 Claims.
7 (Granted under the act of March a, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.
The subject of this invention is an apparatus for training in gunfire and is intended more particularly for training in machine gunfire though useful in training in any automatic gunfire.
In training men in the firing of machine guns it is necessary that they be taught to aim the gun properly; to fire proper bursts; to clear stoppages and to execute the various forms of firing carried out by machine gun crews.
The main object of the present invention is to instruct in the various subjects set forth above and this object is attained by providing means for producing a visual duplication of the cone of fire; an aural duplication of the sound of the shots fired; and means for simulating stoppages in the firing of the gun.
With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
A practical embodiment of the invention is 11- lustrated in the accompanying drawing, wherein:
Fig. 1 is a view in side elevation of a machine 811 Fig. 2 is a vertical longitudinal section through the sound box;
Fig. 3 is a horizontal section of the same;
Fig. 4 is a detail view in side elevation of the spring contact fingers in place on the trigger of a machine gun; and
Fig. 5 is a wiring diagram.
Referring to the drawing by numerals of reference:
There is shown a machine gun I provided with the usual bufier assembly 2, hand grip 3, trigger 4 and water jacket 5. While the gun herein shown is provided with a water jacket, it is to be understood that such jacket is not essential as the device may be attached to the barrel of any type of machine gun.
A bar 6 is provided with means, as for instance the loops 'I-|, for attachment to the gun preferably in such position that the bar lies below the gun barrel. A thumb screw 8 may be provided in the rear end of the bar for the purpose of bringing the longitudinal axis of the bar into parallelism with the axis of the bore of the gun barrel. Toward the forward end of the bar a strap 9 is provided for holding a lens casing H] which may be adjusted along the bar by sliding the strap thereon until a proper focal position is reached. The lens in the casing may be subject to further minute adjustments through the micrometer adjustment usually provided on the casing.
Secured to the bar is a container 1 I, preferably made of light resilient wood one side of which is hinged as at l2l2 to permit access to the interior, and is provided with an opening l3 to permit egress of sound waves.
ithin the container a partition I4 may be provided dividing the container into upper and lower compartments and so positioned as to be out of contact with one wall of the container, as herein shown the wall l5, so that vibration of said wall will not be dampened.
The cells iii-l6 of a battery are positioned within the container, and conveniently in the lower compartment; the cells being connected in series and through the wire H to one terminal of an electro-magnet I8 secured to the partition I l, from the other terminal of which magnet a wire I9 leads to a binding post 20 on the top of the container. Associated with the electro-magnet i8 is a clapper 2| so positioned as to strike the wall i5 intermittently when the electro-magnet is energized.
An aperture is formed in the front wall 22 of the container, through which is inserted the frame or body portion 23 of a fiash light leaving the lens portion 24 protruding so that the flash light battery may be renewed from the front end.
A lead wire 25 is secured to the frame of the fiash light to form contact with the positive pole of its battery and this wire also connects with the binding post 20. From the negative pole of the flash light battery a lead wire 26 extends to one terminal 2'! of a switch 28, and from another terminal 29 of said switch a conductor 30 leads to the negative pole of the battery composed of the cells lB-I6. From the other terminals 3| and 32, respectively, conductors 33 and 34 lead to the respective binding posts 35 and 36 also portioned on the top of the container.
Clamped on the trigger 4, through means of a strap 31 and thumb screw 38 is an insulating block 39 carrying the spring fingers 40, 4| and 42. On the upper finger 42 is secured an insulating block 43, spaced slightly from the bufier assembly 2 so that when the trigger is operated the block will contact the assembly 2 and cause the fingers to be brought into contact with each other. From the fingers 4| and 42 the respective conductors 44 and 45 lead to the binding posts 35 and 36, while, from the finger 40, a conductor 46 leads to the binding post 20.
The operation of the device is as follows: The lens in the casing Ill being properly focused, the gunner sights the gun on the target and pulls the trigger. When the trigger is pulled the insulating block 43 is brought into engagement with the bufier assembly 2 causing the fingers 40, 4| and 42 to contact thereby establishing a circuit through conductor l1, electro-magnet [8, conductor l9, binding post 20, conductor 46, finger 46, finger 42, conductor 45, binding post 36, conductor 34, terminals 32 and 29 (when the switch is closed), conductor 30 to battery l6; thus energizing the electro-magnet and operating the clapper to simulate the sound of firing by striking the side of the container. At the same time current fiows from the search light battery through conductor 25, binding post 26, conductor 46, finger 40, finger 4!, binding post 35, terminals 3| and 21 (when the switch is closed), conductor 26 to the flash light battery, thus energizing the light and projecting a cone of rays toward the target in simulation of the cone produced by the paths of bullets.
It is evident then that the device will permit the firing of bursts of long or short duration and that the instructor may, at will, produce stoppages by throwing the switch to break the circuits, thus compelling the gunner to perform the usual acts necessary to clear the customary stoppages before the gun will again fire.
I claim:
