Sectional display for samples of sheet material

Claim 1

A sectional display for samples of sheet material comprising a plurality of backs a. rectangular in form and having b. longitudinal edges and c. transverse edges, d. webs extending outwardly from said backs forwardly thereof and along the longitudinal edges of said backs, e. flanges extending inwardly from the outer edges of said backs and toward one another to form facing grooves on each back for the reception of the material to be displayed f. said grooves being open at their ends for the endwise reception of the sheet material to be displayed g. ribs extending rearwardly from said backs at the rearward surface thereof to reinforce said backs and spaced from certain of the edges of the backs to form marginal areas at said edges, h. pairs of spaced pins extending rearwardly outwardly from said backs along lines normal to the longitudinal and transverse edges of each of the backs, the axes of all of said pins being parallel i. said pins of each pair being the same distance apart and j. the outermost pin of each pair being the same distance from the edge of the back adjacent which it is disposed, k. a plurality of flat platelike cleats each having four spaced holes therein arranged along a straight line with l. the distance between each outer and its adjacent inner hole being equal to the distance between each pair of the pins and m. the distance between the pair of inner holes being equal to twice the distance between the outermost pin and the edge of the back which it adjoins, n. the pins on each back being disposed opposite a corresponding pin on an aligned adjacent back.
