Abstract
Abstract A holder for securing in position a plurality of slides to enable a composite photograph thereof to be taken, for example for cataloguing a slide library. The holder comprises planar base and secondary frames to receive on their surfaces the slides to be photographed. The frames are provided with transparent sections beneath the areas to be covered by the film portions of the slides when mounted on them, the transparent sections of one frame being aligned with the transparent sections of the other when the frames are mounted in operative position. In this manner the entire film portion of each slide is exposed to the photographic means. In a preferred form of the invention, the slides are mounted on the frame so that the opaque edge portions of the slides on one of the frames overlap opaque edge portions of slides on the other frame, thereby increasing the number of slides which may be included in the composite photograph.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
208 words
A holder to secure in position a plurality of slides, each slide having a film portion circumscribed at its top, bottom and sides by an opaque edge portion, to enable taking a composite photograph thereof with camera means, external thereto, the holder comprising: (a) a planar base frame to receive on its surface certain of the slides to be photographed; (b) a planar secondary frame to be positioned in operative position over the base frame and adjacent and parallel thereto, this secondary frame to receive on its surface other of the slides to be photographed; and (c) transparent portions in the frames of sufficient area and positioned, with respect to the film portions of the slides when the slides are mounted on the frames, to underlie those film portions, these transparent portions of one frame being positioned with respect to the transparent portions of the other frame when in operative position so that the entire film portion of each slide may be exposed to the camera means; and (d) means associated with frames to position the slides in a plurality of rows or columns over the transparent portions of the frames and to releasably hold the slides flushly on the surface of the corresponding frame in that position.
Claim 2
Dependent Claim
208 words
A holder to secure in position a plurality of slides, each slide having a film portion circumscribed at its top, bottom and sides by an opaque edge portion, to enable taking a composite photograph thereof with camera means, external thereto, the holder comprising: (a) a planar base frame to receive on its surface certain of the slides to be photographed; (b) a planar secondary frame to be positioned in operative position over the base frame and adjacent and parallel thereto, this secondary frame to receive on its surface other of the slides to be photographed; and (c) transparent portions in the frames of sufficient area and positioned, with respect to the film portions of the slides when the slides are mounted on the frames, to underlie those film portions, these transparent portions of one frame being positioned with respect to the transparent portions of the other frame when in operative position so that the entire film portion of each slide may be exposed to the camera means; and (d) means associated with frames to position the slides in a plurality of rows or columns over the transparent portions of the frames and to releasably hold the slides flushly on the surface of the corresponding frame in that position.
Claim 3
Dependent Claim
33 words
A holder according to claim 1 wherein the frames are hingedly secured to each other along one edge of each to enable pivoting of the frame between open position and closed, operative position.
Claim 4
Dependent Claim
78 words
A holder according to claim 2 further comprising: (e) a plate to be positioned in operative position over the base and secondary frames, this plate being opaque and having transparent sections of a size and positioned with respect to the transparent portions of the base and secondary frames when the frames and plate are in operative position so that the film portion of each slide may be exposed to camera means on the plate side of the holder.
Claim 5
Dependent Claim
29 words
A holder according to claim 3 wherein the plate is hingedly secured to the edge of the base frame opposite to that to which the secondary frame is secured.
Claim 6
Dependent Claim
57 words
A holder according to claim 2 or 3 wherein the transparent sections are positioned on the frames and plate so that the opaque top and bottom edge portions of slides in rows on one frame will overlap the opaque bottom and top edge portions of slides on adjacent rows on the other frame when in operative position.
Claim 7
Dependent Claim
28 words
A holder according to claim 2 wherein the base and secondary frames are provided with shoulders defining channels to position the slides properly in rows on the frames.
Claim 8
Dependent Claim
28 words
A holder according to claim 4 wherein the base and secondary frames are provided with shoulders defining channels to position the slides properly in rows on the frames.
Claim 9
Dependent Claim
14 words
A holder according to claim 4 wherein opaque portions of the plate are white.
Claim 10
Dependent Claim
19 words
A holder according to claim 2 or 3 wherein the transparent sections are aligned in both rows and columns.
Claim 11
Dependent Claim
52 words
A holder according to claim 3 wherein the undersides of the secondary frame and plate are further provided with resilient material to bear against the marginal portions of the slides when in position and the secondary plate and frame are in operative position, to hold the slides securely on their respective plates.
Claim 12
Independent Claim
54 words
A method of holding a plurality of slides, each slide having a film portion circumscribed at its top, bottom and sides by an opaque edge portion for a composite photograph thereof comprising holding the slides in two planes and overlapping the edge portions of the slides of one plane with those of the other.
Claim 13
Independent Claim
54 words
A method of holding a plurality of slides, each slide having a film portion circumscribed at its top, bottom and sides by an opaque edge portion for a composite photograph thereof comprising holding the slides in two planes and overlapping the edge portions of the slides of one plane with those of the other.
Claim 14
Dependent Claim
67 words
A method according to claim 11 comprising positioning of reference indicia on the side of the slides from which the photograph is to be taken, in association with the slides as a means to identify the slides, and back lighting the slides to provide an image of the film portion of the slides for the photograph, and front lighting to illuminate the reference numerals for the photograph.
