Abstract

This invention pertains to apparatus adapted to make an immediate record as by a photograph of a theoretical hit such as in hunting wild game. There is shown both a mechanical and an electrically actuated means for causing this theoretical hit to be exposed on the film of a camera which is carried by and actuated with the pulling of the trigger of the gun. The distance, trajectory and windage factors are reflected in this photographic record. The hunter using the gun fires a blank cartridge rather than a real cartridge so that this photographic record indicates what results this hunter would have achieved had a real bullet been fired.

Claims

1. A recording system superimposed on a camera carried by a gun, said system adapted to predict the theoretical impact point of a '"'"''"'"''"'"''"'"'hit'"'"''"'"''"'"''"'"' such as is achieved in bloodless hunting, said system including:

(a) a rifle scope;

(b) a reflex camera secured to the viewing end of the scope in a light-tight manner so that the image seen in the scope is also seen in the view finder of the camera and when the camera shutter is actuated the image through the scope is also received and recorded on a film in the camera;

(c) indicator means for placing in the scope-projected image an accurate indication of those operator compensations required in hunting, these compensations including windage, trajectory and distance of a theoretically fired bullet;

(d) an electronic circuit, which when selectively connected to a battery source of power and the trigger of the gun is pulled automatically moves an indicating positioning member in a vertical manner to establish a trajectory allowance and a distance adjustment and by means of a windage indicator transducer which is actuated by a wind-engaged sail-like member moved transversely of the line of sight by the force of the wind, this transducer displacing said positioning member horizontally, whereby both vertical and horizontal movements are at their maximum established condition as and when the film is exposed, and (e) means responsive to the pulling of a trigger of the gun to create a firing condition, said means opening the camera shutter to expose the film in the camera and on said film to record the view through the scope and at the same time to record on this same film the position of the indicator means responsive to the windage trajectory and distance compensation adjustments made by the operator.

2. A recording system as in claim 1 in which the distance computation in the electronic circuit includes a laser beam transmitter and receiver, each carried on the gun with said transmitter and receiver aligned with the rifle scope, both the transmitter and the receiver actuated with the pulling of the trigger.

3. A recording system as in claim 2 in which the indicating positioning member includes an electrostatic box in which a charged particle is freely movable in a vacuum conditioned means established within said rectangularly configured box having substantially transparent and electrically charged front and rear walls, said box having four charged plates carried within the box and near the sides, one of these at each of the sides with these plates arranged at 90* to each other;

the circuit for the distance and windage and in an adjusted balanced condition causing the charged particle to be suspended at a determined central position within said box and at the time of firing the flow to the charged plates is unbalanced by a correction means so as to move the particle from its central position an amount corresponding to the distance and windage influence on a theoretically fired bullet.

4. A recording system as in claim 3 in which said circuit includes two mono-stable multivibrators, a flip-flop and a transistor amplifier and with the pulling of the trigger one mono-stable multivibrator releases a single pulse to set the flip-flop and causing a vertical control capacitor to vertically position the indicating particle, and at the same time the windage transducer is moved by the sail-like attached member to adjust the same indicating particle horizontally and at the pulling of the trigger a transmitted laser beam which is in coincidence with the axis of the gun barrel is sent toward the target and after striking the target and returning to the laser receiver causes the other mono-stable multivibrator to reset the flip-flop to normal condition, this received signal also actuates a camera trigger control circuit to take the picture.

5. A recording system superimposed on a camera carried by a gun, said system adapted to predict the theoretical impact point of a '"'"''"'"''"'"''"'"'hit'"'"''"'"''"'"''"'"' such as is achieved in bloodless hunting, said system including:

(a) a rifle scope;

(b) a reflex camera secured to the viewing end of the scope in a light-tight manner so that the image seen in the scope is also seen in the view finder of the camera and when the camera shutter is actuated the image through the scope is also received and recorded on a film in the camera;

(c) indicator means for placing in the scope-projected image an accurate indication of those operator compensations required in hunting, these compensations including windage, trajectory and distance of a theoretically fired bullet;

(d) a mechanical means for selectively moving a pair of stiff cross-hairs normally arranged at substantially right angles to each other and disposed adjacent the film in the focal plane of the camera, the shifting of the hairs and point of intersection corresponding to the desired compensation for windage and trajectory, this mechanical means including two rotatably mounted setting rings arranged in a substantially parallel condition, each ring carrying a support post to which is secured one end of a cross-hair while the other end of the cross-hair is attached to a swivel ring carried by a fixed support, the cross-hairs normally disposed at right angles to each other and laying in parallel planes and adjacent each other and adjacent the film being exposed, and (e) means responsive to the pulling of a trigger of the gun to create a firing condition, said means opening the camera shutter to expose the film in the camera and on said film to record the view through the scope and at the same time to record on this same film the position of the indicator means responsive to the windage trajectory and distance compensation adjustments made by the operator.
