ADALBERT SZALARDI, OF NEW YORK, N. Y.

CAMERA GUN.

Application led February 26, 1925. 'Serial No. 11,757.

To all whom it may concern.'

Be it known that I, ADALBERT SZALARDT, a citizen of Hungary, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Camera Guns, of which the following is a specification.

This invention relates to weapons for self defense and it especially has relation to a. combination of guns with photographic cameras for the purpose to be more fully detailed hereinafter.

It very often happens that policemen, military persons, but even private people are obliged to use guns for self defense. After such lan occurrence the courts usually have to determine the legality or necessity of the use of guns and have to depend on witnesses, if any, who are very often absolutely unreliable on account of the suddenness of the affair and the excitement accompanying they same. But more often there are no outside witnesses at all except the actors of the drama. This invention has the main object to be an absolutely reliable aid to the courts in such events since the combination of a gun with a camera will result in taking a picture of all events where the gun has been fired even giving the duration and time of the occurrence. My invention will result in quicker and more just processes of law which at the same time will be less eX- pensive than they are to day. Fleeingv automobiles with the criminals therein and so on m'ay also be photographed while being shot at.

My invention may be useful in case of Sport, military training and scientific research too.

One embodiment of my invention is shown in the accompanying drawings, in which- Fig. 1 is a sectional elevation of my invention shown as applied on a un, while Fig. 2 is a side elevation o a pistol equipped with the camera accordmg to my invention, the scale of the second figure being comparatively small.

Referring more closely to the drawings, the character 1 indicates the outside barrel of a gun having the inside barrel or sleeve 2 therein which in case of repeating guns will run backwards after every shot. 3 is the bullet which will be tired in the direction of the arrow in front of the same.

Sleeve 2 has an opening 4 through which the with 'opening 4 while sleeve 2 is running p backwards. A piston 7 is running in tube 6 and has the teeth 8 at a portion of the same while being in tight engagement with the tube at its other parts. Tube 6 has an opening 9 through which the teeth of gear 10 may engage the teeth 8. The gases will drive piston 7 downwards while after the pressure is spent the spring 11 will return the same into its original posit-ion. The piston 7 has a pin 18 at its'lower end which runs in the slot 14 of the tube-6 and prevents the turning of piston 7 and keeps the teeth 8 in the pl-ane of gear 10. The screw 15 serves to hold spring 11 and to regulate the same.

At every shot the piston 7 executes a down and up motion and the gear 10 will make a similar oscillating movement en shaft 16 on which it loosely sits. Shaft 16 carries ratchet wheel 17 secured thereon, cooperating with ratchet 18 secured on gear 10. Ratchet 18 will turn ratchet wheel 17 when piston 7 is pressed upwardly by spring 11 and so the shaft 16 will make a turning motion in a reverse direction to that of the clock. The same manner drum 19 keyed to shaft 16 will turn and carries sensitive film 20 the one end of which is secured to it.`

The movement of piston 7 is so regulated that it should answer to the length necessary for taking a picture and to an additional length of the lm indicating the time elapsed.

Lens 22 throws the picture on the film 20 and their relation is such that the aim of the shot will be the object of the picture. Lens 22 is secured to cover 23 which provides the necessary camera with a dark space. In said dark compartment back of the lens there is shutter 24 which lalso is operated by the combustion gases reaching the same by the tube 25. While piston 7 is pushed downwards the shutter 24 will open and close and the film 2O being in rest will show a photographic exposure. When spring 11 kicks piston 7 backwards, drum 19 and drum 21 therewith, will be turned and the used up portion of film 2O will be rolled up on drum 19, while fresh film will come into the projection space of the lens from the drum 21. In the inside of the cover 23 is arranged the Per clock work 33 rotatable Iaround shaft 32. Drum 26 is rotated by the clock work and it has at its periphery formations 27 to show the elapse of time. Clockwork 33 carries pin 31 which is struck by the pin 13 on piston 7 when it travels downwards, and so the clockwork is turned in the direction of the arrow, as long as drum 26 reaches the dotted position when formations 27 will strike the film 20. The film will be reached by the formation which represents the time moment of the shot from which the time moment of the shot may be determined by the formation in the film. Spring 28 returns the clock work into its original position; an arm 29 from the frame of the clock work leans Iagainst the spring 28 so that if the clock work oscillates in the reversed direction it also should be returned into its original position. 23 cover also has an opening 30 which serves to insert the key for winding the clock work. The clock work may also have a moving paper to be punched through opening 30 for indicating the time as is done in the well known control clocks. Within cover 23 is formed through appropriate partitions a dark camera (not shown), which prevents any kind of a li ht reaching the lm 20, including the possi le light of the combustion gases.

In case of darkness the light for taking the pictures is provided by a light producing medium like magnesium being mixed to the gun powder. It also may be provided by a separate lighting bullet being shot through an auxiliary tube simultaneously with the firing of the gun, or by a separate electric reflector.

In Fig. 2 I show a gun combined with a camera as described with the exception however that tubes 6 and 25 are on the outside. Casing 23 is kept locked and a key may be inserted into hole 34: for opening the same. The key for opening the camera may be kept by the superiors of the policemen and the like equipped with the pistol so that the user cannot get to the pictures taken. The mechanism of the gun and that of the camera are not interconnected in any manner so that any trouble with the camera will still leave the gun in a perfect condition for possible use.

What I claim, is 1. In a gun, VVphotographic camera combined with an obect aimed t y said gun, said camera being adapted to take a picture of said object, and means automatically operated by nthe cgmbusiion ases to actua e sald camera upon the firing o e gun.

2. In a gun of claim 1, a clock work adapted to register the elapse of the time, a sensi` tized medium in said camera adapted to take pictures thereon, and means in connection with said clock work whereby the moment of tiring of said gun may be registeed on said sensitized medium.

3. In a gun of claim 1, means in connection with the explosives used for tiring said gun whereby the object aimed at and to be photographed will be illuminated.

4. In a gun of claim 1, said camera being enclosed in a casing locked by a key, a film rolled on a drum in said casing, a piston in said casing being o erated by the combustion gases through a tu e, teeth on said piston, a ratchet wheel and ratchet operated from the teeth on-said piston andl moving said film from the aforementioned drum unto a second drum, a second tube for the combustion'gases leading to a shutter of the usual make and operating the same through the gas pressure.

5. In a gun of claim 1, a casing for said camera containing a dark compartment, a sensitized film wound up in said dark compartment being exposed to a portion of the same to the 1i ht coming from the lens of the camera, a s utter for said lens bein operated simultaneously to the firing o the gun, a clockwork in said camera recording the time as usual, time indicating formations on said clockwork and means to bring one of said time indicating formations in contact with said ilm at the moment of the firing of the gun.

v Signed at New York, in the county of New York and State of New York, this 25th day of February, A. D. 1925.

ADALBERT SZALARDI.
