Gibson Graph Comparator Camera

Object Details

Description
This instrument is in a case of stained wood veneer that is hinged at the back and has a clasp on the front. The camera is aluminum, brass, plastic, wood, and paper. Two sections on the top can be removed. On the right side is the on-off toggle, a mechanical counter, and a lever which engages the film take-up sprocket. On the front are two dials that use a "clock-like" gear system; a crank which sets the "hands" of the dials, and a crank that advances the film and the mechanical counter. On the left side is a lever which may be used as the shutter and exposure system. On the back is a knob with a spring for placing the roll of film. Two connecting wheels with a spring band advance both the advance sprocket and take-up spool of exposed film. There also is an electrical cord and plug. The inside assembly has five compartments. An electric light box, two sprockets and two spools for the film are in the back compartment. The bar graph setting calibration mechanism and the film advance system are in the four front compartments.
