Section V. COPYBOARD CARRIAGE ASSEMBLY
The copyboard carriage assembly consists primarily of the axle
and tube assembly (2, fig. 6-8), copyboard frames (12), and the
carriage base plate (3-. The copyboard assembly is secured to
the axle and tube assembly which is able to swing through a
180arc. A drivescrew moves the entire copyboard carriage
assembly backward or forward on the camera rail. The axle and
tube assembly is supported by the two frames (12) and rotates
freely between them on its axle. The frames in turn are each
bolted and pinned to the carriage base plate for rigidity. Two
brackets (8) for mounting the arc lamp arm brackets are
secured to the carriage base plate. A cross brace assembly (5)
with internal rollers rides on the camera rail and offsets the
weight of the arm brackets and arc lamps. A limit switch bracket
(4) is mounted on top to limit travel of the assembly.
