SPECIFICATION forming part of Letters Patent No. 745,202, dated November 24, 1903.

Application filed May 15,1902. erial No. 107,449. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR 0. LA MAY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographic-Plate Holders; and l-do hereby declare the folio ving to be a full clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to photo graphieplate holders adapted to carry and retain securely photographic plates of different sizes; and it consists in the improved construction hereinafter described.

In the drawings, Figure l is a front view of the plate -holder embodying my improvements with the slide withdrawn and a small plate held in position. Fig. 2 is a perspective View showing one of the holding-springs.

Similar reference-numerals in the two ures indicate similar parts.

The frame of the holder (indicated by 1) may be of the usual or anysuitahle construction, and arranged within it and on opposite sides thereof are the plate-retaining springarms, (indicated by 2,) four of said arms being employed, one for each cornerofthe plate, and for convenience the two springs on the same side of the holder-frame are made of one continuous piece of spring metal. Each of the spring-arms is provided with one or more small shoulders 8 and with the ears 13,e:;tending over them, forming notches or recesses adapted to engage with the corners of the small plate 4, preventing its movement longitudinally of the springs and holding it firmly in the holder, the arms readily adjusting themselves to plates of different sizes. When using or holding a plate for which the holder is primarily adapted, the springs are held by the glass plate back against the sides of the frame, and the plate is retained by any suitable means, such as are ordinarily employed in plate-holders of this description, so the holding-springs forming the subject-matter of my present invention may be auxiliary to the holding device for the larger sized plate, if desired, and may therefore be applied to holders already in use at avery slight additional cost. I prefer, however, that the springs shall hold both sizes of plates, both large and small, without other devices, and for this purpose they are provided with the over hanging ears or lugs 16, extending over the shoulders, as shown. The shoulders 6 at the ends of the springs will engage the ends of the larger plates and prevent longitudinal movement, and the ears 16 prevent forward movement in the same manner as the cars 13. It will be understood that, if desired, each of the spring-arms may be providedwith a greater number of projections or notches, so as to retain in position differentsized plates; but for all practical purposes onein each arm is sufiicient.

The same holding-springs may be applied to the edges of auxiliary plates or kits held in the plate-holder by the usual plate-retaining devices, if desired; but their employment in the holder itself renders the latter capable of use without the use of a kit.

I claim as my invention- 1. The combination with the frame of a photographic-plate holder, of a plurality of platesprings arranged in the interior of the frame each having the plate-retaining shoulders at the free ends and at a point between the latter and the points of attachment to the holder, said shoulders being formed by bending the springs transversely, and provided also with the lugs at the sides of the shouldersto form therewith recesses for the corners of plates.

2. The combination with a plate-holder, of a plurality of plate-retaining spring-arms at the sides thereof each having a shoulder and an overhanging portion at a distance from its point of attachment said shoulders and ears being adapted to engage and retain the cor- 11ers of a photographic plate.

3. The combination with a plate-holder, of two oppositely arranged plate --retaining springs secured at their middles in the sides of the holder and having at each end the shoulders formed by bending the springs transversely and provided with the ears extending over said shoulders to form recesses for the corners of the plates.

ARTHUR O. LA MAY.
