Abstract
Abstract An adjustable roll holding rack particularly designed to facilitate width adjustment and loading in a dark room atmosphere and including a pair of adjustable roll holding brackets each having a generally G-shaped spindle receiving slot for journalling in captured relationship the roll mounting pins on which the supply rolls of strip material to be processed are carried and each bracket being provided with a wide mouth entrance leading into said slot to guide the spool spindle into the slot for easy loading in the dark room atmosphere, said brackets also including supporting arms adapted to be securely anchored in the desired adjusted spaced apart relation to accommodate rolls of different widths of strip material, with means for releasably holding the brackets in the desired adjusted position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
A roll holder for mounting supply rolls of photographic strip material to be processed, said holder comprising: a transversely extending fixed mounting rod, a fixed adjustment element spaced rearwardly from said mounting rod, a pair of laterally extending roll mounting pin elements for journaling a supply roll of photographic strip material to be processed, a pair of spaced apart roll holding brackets, each bracket including: a hub element rotatably and slidably mounted on said transverse mounting rod, a roll mounting arm fixed to said hub element and extending forwardly therefrom, an anchoring arm fixed to said hub element and extending rearwardly therefrom and having an interlocking element adjustably connected to said adjustment element to anchor the bracket in the desired spaced apart from the other bracket of said pair, said roll mounting arm including a pin receiving slot oriented to rotatably mount in captured relationship the mounting pins on which a roll of strip material to be processed is carried.
Claim 2
Dependent Claim
160 words
A roll holder for mounting supply rolls of photographic strip material to be processed, said holder comprising: a transversely extending fixed mounting rod, a fixed adjustment element spaced rearwardly from said mounting rod, a pair of laterally extending roll mounting pin elements for journaling a supply roll of photographic strip material to be processed, a pair of spaced apart roll holding brackets, each bracket including: a hub element rotatably and slidably mounted on said transverse mounting rod, a roll mounting arm fixed to said hub element and extending forwardly therefrom, an anchoring arm fixed to said hub element and extending rearwardly therefrom and having an interlocking element adjustably connected to said adjustment element to anchor the bracket in the desired spaced apart from the other bracket of said pair, said roll mounting arm including a pin receiving slot oriented to rotatably mount in captured relationship the mounting pins on which a roll of strip material to be processed is carried.
Claim 3
Dependent Claim
91 words
The structure set forth in claim 1 and said fixed adjustment element having a plurality of spaced apart apertures for selectively receiving the interlocking element of said anchoring arm and extending transversely in spaced parallel relation to said mounting rod, and said interlocking element comprising an upwardly extending hook fixed to the rear portion of said anchoring arm and adapted to be upwardly received in a selected aperture in said ajustment element to positively hold the forwardly extending mounting arm in the desired selected laterally adjusted position on the mounting rod.
Claim 4
Dependent Claim
18 words
The structure set forth in claim 2 and releasable means for holding said hook in said selected aperture.
Claim 5
Dependent Claim
47 words
The structure set forth in claim 3 wherein said releasable means constitutes a forwardly extending roll mounting arm of sufficient weight to hold the interlocking hook of the anchoring arm in the selected aperture of said adjustment element during dispensing of the strip material from the roller.
Claim 6
Dependent Claim
54 words
The structure set forth in claim 1 and said pin mounting slot being generally G-shaped with a forwardly facing entrance opening at the upper portion thereof and a forwardly closed retaining slot portion in the lower portion thereof to produce the pin capturing relationship required to hold the roll mounting pins in said brackets.
Claim 7
Dependent Claim
29 words
The structure set forth in claim 5 and said slot having an enlarged entrance opening to facilitate dark room loading of the laterally extending pin elements in said slots.
Claim 8
Dependent Claim
36 words
The structure set forth in claim 1 and said laterally extending pins having retaining elements on the ends thereof, said retaining elements being of greater width than the width of the mounting portion of each slot.
Claim 9
Dependent Claim
29 words
The structure set forth in claim 7 and said retaining elements constituting generally circular flange elements of greater diameter than the width of the mounting portion of each slot.
