Abstract

A traffic-monitoring camera is removably mounted on a housing with its primary lens extending horizontally above the housing. Within the housing are instruments, e.g., clock, to be simultaneously photographed. The housing has a fixed holder to which a lens mount is adjustably affixed and positioned in the housing. An auxiliary wide-angle lens is secured in the mount and positioned with its optical axis horizontally and symmetrically between the instruments. Mirrors and a tube provide a path for the light rays from the auxiliary lens to the camera field.

Claims

1. In a photographic-monitoring device comprising a camera having a camera case within which is an image field and adapted to photograph the monitored object by means of a primary objective on the case defining a first light path entering the case to said field, having automatic film advance and shutter winding, said camera at the same time also photographing a secondary image of instruments, reflected into the image field by means of an auxiliary objective defining a second and separate light path into the body, said instruments being accommodated in a housing removably carrying the case of the camera, the improvement comprising:

said auxiliary objective being a wide-angle lens having an optical axis;

a lens mount holding said lens;

a holder affixed to said housing;

adjustable connecting means attaching said lens mount to said holder and positioning said lens so that its optical axis is generally horizontal; and

mirror means positioned between said lens and the image field to direct light along a path from the lens to said field;

said camera case having a tube encircling said second path and forming an entrance for the light rays into the camera;

whereby when the camera case, with its primary objective, is removed from the housing the auxiliary objective remains with the housing in the previously established position.

2. In a device as set forth in claim 1, wherein said connecting means includes a lateral projection on said mount, said projection having an opening therethrough;

a pair of semispherical clamping elements; and

a screw;

said elements being positioned on opposite sides of said projection with the projection being clamped therebetween by said screw.

3. In a device as set forth in claim 2, wherein said housing includes housing inserts each holding one of said instruments, said housing inserts and instruments being positioned such that the instruments are positioned symmetrically with respect to said optical axis and angularly with respect to each other.

4. In a device as set forth in claim 3 for use with a camera having an aperture-setting means and wherein said device includes;

a slide attached to said housing and movable laterally of said aperture-setting means, said slide having a fork operatively engaging said aperture-setting means whereby movement of the slide will change the aperture setting; and

an aperture scale member and a pointer member, one of said members being affixed to the housing and one to the slide whereby the aperture setting can be read, said scale member being positioned laterally of the camera and so that the scale can be read from the rear of the camera.

5. In a device as set forth in claim 1 for use with a camera having an aperture-setting means and wherein said device includes;

a slide attached to said housing and movable laterally of said aperture-setting means, said slide having a fork operatively engaging said aperture-setting means whereby movement of the slide will change the aperture setting; and

an aperture scale member and a pointer member, one of said members being affixed to the housing and one to the slide whereby the aperture setting can be read, said scale member being positioned laterally of the camera and so that the scale can be read from the rear of the camera.
