Target sight recording apparatus
First Claim
1. In a firearm having a trigger and a telescopic sight through which light from a target zone can pass along the optical axis of the sight through an eyepiece to reach the eye of an observer, target sight recording apparatus comprisingan optical beam splitter element rigid with the telescopic sight for diverting a fraction of the light passing through the telescopic sight along a path extending at an angle to the optical axis,a photographic camera rigid with the telescopic sight and inclined at an angle to receive the deflected light,the camera having an objective lens system, a camera shutter, and a cassette for housing photographic exposure material all aligned along the optical axis of the camera and a shutter releasing device coupled to actuate the camera shutter, andmeans coupling the shutter release device with the trigger of the firearm so that upon operating the trigger the camera shoots the picture which at that instant the observer can view through the telescopic sight.

Abstract
A rifle having a telescopic sight has apparatus for recording the target as seen through the telescopic sight at the instant the trigger is pulled. The apparatus includes a beam splitter for directing to a camera some of the light passing through the telescopic sight. The shutter mechanism of the camera is coupled to the rifle trigger so that the camera will "shoot" the picture of the target when the trigger is pulled. The camera is of the instant-copy type so that pictures of the target can be viewed shortly after "shooting". The apparatus thus enables the ability of a rifleman to be tested without the need for firing live ammunition.

1. In a firearm having a trigger and a telescopic sight through which light from a target zone can pass along the optical axis of the sight through an eyepiece to reach the eye of an observer, target sight recording apparatus comprising
an optical beam splitter element rigid with the telescopic sight for diverting a fraction of the light passing through the telescopic sight along a path extending at an angle to the optical axis, a photographic camera rigid with the telescopic sight and inclined at an angle to receive the deflected light, the camera having an objective lens system, a camera shutter, and a cassette for housing photographic exposure material all aligned along the optical axis of the camera and a shutter releasing device coupled to actuate the camera shutter, and means coupling the shutter release device with the trigger of the firearm so that upon operating the trigger the camera shoots the picture which at that instant the observer can view through the telescopic sight.

13. In combination,
a firearm having a trigger and a sight, a camera having a remotely operable shutter mounted on the firearm to view the target through the sight of the firearm, means coupling the trigger of the firearm with the camera shutter so that upon operating the trigger the camera is operated to shoot the picture at that instant an observer can view through the sight, an eyepiece and a semireflecting mirror both mounted on the firearm, the semireflecting mirror providing a first light path from the camera to the sight and a second light path from the eyepiece to sight, and a film cassette housing a film having a plurality of frames, means rotatably mounting the cassette in the camera for movement into successive ones of a plurality of discrete angular positions to enable a plurality of picture shots to be recorded on the same frame of the film.
