Abstract
Abstract The problem of storing microfiche transparencies, cards, documents, photographs or any other sheets of material in the vertical or inclined position, is solved by a simple rectangular tray with inclined ends and side walls, the inner top portions of which contain vertically extending grooves for receiving a pair of lugs on each side of planar rectangular partitions. The spacing between the lugs is such that the partition is inclined by no more than 30° from the vertical when the lugs on one side of the partition are inserted into adjacent grooves. In the vertical position the lugs are vertically aligned in the same plane as the body of the partition.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
A storage tray for microfiche or other thin sheets of material, comprising a bottom wall; parallel spaced apart side walls extending upwardly from said bottom wall; end walls connected to the ends of said side walls and extending upwardly from said bottom wall; a plurality of vertical grooves in at least a top portion of each said side wall; and at least one partition for insertion into the tray, said partition including substantially planar body means and a pair of lug members near the top of and extending outwardly from each side of said body, whereby upon insertion of said body means into said tray, each lug of each pair may slide into the same one of said grooves for retaining said partition in a vertical position, and each lug of each pair may slide into a different one of said grooves for retaining said partition in an inclined position.
Claim 2
Dependent Claim
150 words
A storage tray for microfiche or other thin sheets of material, comprising a bottom wall; parallel spaced apart side walls extending upwardly from said bottom wall; end walls connected to the ends of said side walls and extending upwardly from said bottom wall; a plurality of vertical grooves in at least a top portion of each said side wall; and at least one partition for insertion into the tray, said partition including substantially planar body means and a pair of lug members near the top of and extending outwardly from each side of said body, whereby upon insertion of said body means into said tray, each lug of each pair may slide into the same one of said grooves for retaining said partition in a vertical position, and each lug of each pair may slide into a different one of said grooves for retaining said partition in an inclined position.
Claim 3
Dependent Claim
37 words
A tray according to claim 1 wherein each said side wall includes a horizontal shoulder at the bottom of said top portion, said grooves extending vertically from a top edge of each side wall to said shoulder.
Claim 4
Dependent Claim
36 words
A tray according to claim 1 wherein said end walls are inclined outwardly, the angle of inclination of said end walls being substantially identical to the angle of inclination of said partition in the inclined position.
Claim 5
Dependent Claim
33 words
A tray according to claim 1, 2 or 3 including upwardly extending bead means on the top surface of said bottom wall for retaining the bottom end of said partition in one position.
