Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A mount for X-ray films comprising a sheet of material having an opening therein, a depression about the edges of said opening, said depression including an inwardly directed flange forming a smaller window below the plane of the sheet, a series of elongated, non-flexible lips in the plane of the sheet of material extending into said opening, but terminating short of the edges of the flange, said lips being peripherally spaced about said opening at each of the four sides thereof and extending into said opening to a lesser degree than does the depressed flange aforesaid, the elongated lips forming a co-planar discontinuous flange parallel to the depressed flange, and having forward edges which are rounded along their length and are parallel to the edges of and facing said opening to thereby offer a cam surface to film being inserted into the opening.
