Abstract

782,530. Supports for optical apparatus. McALLISTER, Inc., J. G. April 15, 1955, No. 10906/55. Class 97(1) In order to reduce the horizontal component in the movement of the upper end of a boom which may carry a kiriematograph camera, the lower end is slidable and the mid point of the boom is pivoted to an arm pivoted to a supporting base. Parallelogram linkages 38, 44 are preferably provided and maintain the camera 27 at a fixed orientation while it is moved vertically. As shown, boom 12 is twice the length of the arm 14 and the pivot 16 lies in the plane of movement of the pivot 19, so that the camera moves in a straight line normal to the plane as slide 20 is drawn along rails 23 by the movement of piston 32<SP>1</SP> in cylinder 31 under hydraulic pressure. Links 38 and 44. are connected by bell-crank levers 39 freely rotatable on pivot 13. The inclination of lever 35 can be adjusted relative to the movable base 26 so that the camera can be set at the desired angular position. The camera can also be adjusted about pivots 29.
