Abstract
Abstract A device for supporting a strip of photographic film and for preventing the same from curling during the drying step of developing thereof. A body portion is provided with at least one pair of hook members extending from an edge thereof. The hook members are arranged spaced apart on said edge to enable them to pass through and be positioned within the sprocket holes adjacent end frames of the film strip. One such device may be positioned at the top of a strip of film to support the same on a hanging line or pin for drying; a second device may be positioned at the bottom edge of the film strip to prevent the same from curling during said drying of the strip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A device for use in the selective supporting and weighting of a strip of photographic film having parallel rows of sprocket holes in hanging disposition comprising, a one-piece body including a pair of opposed surfaces, arm means rigid with and projecting beyond one of said surfaces to terminate in an outer end remote from said surface, a pair of return bent hooks rigid with said arm means proximate the outer end thereof and projecting laterally therefrom, the hooks of said pair of hooks being spaced from each other a distance approximately the same as the distance between the parallel rows of sprocket holes whereby said pair of hooks may be inserted within respective ones of the sprocket holes and means on said body engageable with a support for suspending the strip in said hanging disposition.
Claim 2
Independent Claim
135 words
A device for use in the selective supporting and weighting of a strip of photographic film having parallel rows of sprocket holes in hanging disposition comprising, a one-piece body including a pair of opposed surfaces, arm means rigid with and projecting beyond one of said surfaces to terminate in an outer end remote from said surface, a pair of return bent hooks rigid with said arm means proximate the outer end thereof and projecting laterally therefrom, the hooks of said pair of hooks being spaced from each other a distance approximately the same as the distance between the parallel rows of sprocket holes whereby said pair of hooks may be inserted within respective ones of the sprocket holes and means on said body engageable with a support for suspending the strip in said hanging disposition.
Claim 3
Dependent Claim
102 words
The device of claim 1 including second arm means rigid with and projecting beyond the second of said surfaces to terminate in an outer end remote from said second surface, and a second pair of return bent hooks rigid with said second arm means proximate the outer end thereof and projecting laterally therefrom, the hooks of said second pair of hooks being spaced from each other a distance approximately the same as the distance between the parallel rows of sprocket holes and selectively constituting both said means for suspending the strip and means for insertion within respective ones of the sprocket holes.
