UNITED STATES EDWARD LINDER, OF PLAELPHL, PENNSYLVANIA.

TRAY FOB OBHTHALMIG TEST LENSES.

Application led April 2, 1926.

This invention relates to trays, and more particularly to a tray which embodies a plurality of recessed and slotted rectangular sections for receiving an ophthalmic test lens in a fixed vertical or angularly disposed position and in such Lmanner as to protect the lenses and facilitate the placement or removal from the tray of any individual test' lens.

The principal object of the invention is to provide a tray for ophthalmic test lenses, which is designed to accommodate a relatively large number of lenses, each encased in a flanged rim of uniform size, and adapted to be inserted in slots provided therefor in the tray in equally spaced row formation, for the safe, rapid and convenient handling and storing of a large number of test lenses, said trays adapted to be placed in a cabinet or analogous structures designed for receiving a plurality of such trays.

Another object of the invention is to provide an ophthalmic test lens tray comprising a frame vof rectangular' formation, with a plurality of lens tray sections secured therein, and extended in parallelism between the two opposite ends of the tray frame and said tray sections provided with a plurality of spaced longitudinal troughs. The troughs in each of the tray sections are provided with a plurality .of transverse slots of a width sustantially equal to the thickness of the metallic rim in which a standard test lens is encased, and the metallic rim is further provided with a laterally extending flange on `one side thereof and about the perimeter' of the lens, for the engagement of the said flange on the edge portion of a transverse slotl in one of said tray sections when the metallic rim containing a test lens is insei-ted therein.

Another object of the invention is to provide a test lens tray as specified, which is light in weight, durable in construction, compact in design, and particularly adapted to .be used for the purpose for which it is designed. l

Other objects of the invention will ap- Y pear in the following detail description, and

in the Aaccompanying drawing, wherein:

Ficfure l--is a to lan view of the tra .b knv v Figure 2-1s a transverse sectional view i 1% n on the une 2.-2 of Figure 1. w

Serial No. 99,419.

`Figure l-is a bottom plan view of the tray partly in section. f

Figure -is a detail view of a mounted ophthalmic test lens. l Y

Referring more particularly to the drawing, the invention comprises a rectangular frame 10 of inverted L-cross sectional' formation with the upper laterally extending flanges 11 turned inwardly. Formed integrally and connecting opposite flanges 11, are a plurality of relatively narrowv strips 12 which are spaced to divide the frame 10 into a plurality of rectangular open spaces 13, adapted to receive a plurality of'llens tray sections 14 which will be hereinafter more specifically described. l

The lens tray sections 14 are secured in the open spaces 13, and to said frame 10 by means of a plurality of U-shaped clamping strips 15 which extend along theundersides of the said strips 12, and throughout the length thereof, and clamp the laterally extended side edges of the lens tray section between the under surface of the strips l2 and the spaced parallel edges of the U-shapeol clamping strips 15. The clamping strips l5 are secured to the supporting strips 12 by means of suitable machine screws which extend downward for threaded engagement with the clamping strips 15. i

The lens tray sections 14 previously referred to, are preferably formed of sheet metal of a suitable gage and are provided with a plurality of spaced depressions or troughs 16 of any suitable shape which extend throughout their lengths. The troughs 16 are further provided with spaced transversely extended lens receiving slots 17 which extend partially into the laterally extending side edges of the tray sections 14.

The lens receiving slots 17 are spaced a sufficient distance to provide a supporting surface between each of the slots for engagement by a flanged shoulder 18, provided on a standard ophthalmic test lens 19,; The shoulder 18 extends laterally fromone face about the circumferential edge of the lens, the latter being surrounded by a metallic rim 20, as illustrated in yFigure 5 of the drawing. i

The outer laterally extending side edge 21 of the two end trays abut the'inner sides of opposite side members of the frame 10,y and are secured against the under surface of the flanges 11, by means of a pair of suitable ioo rio

retaining bars 22. The bars 22 have their upper edges spaced from the flanges 1l, so as to snugly receive the edges of the tray sections.

If it is so desired, the frame 10 comprising the test lens trays may be fitted on a suitable rectangular wooden base, in any convenient and well-known manner, and the bottom surface of said base may be faced with felt or analogous material, so as not to mar the surface of a table or the like, when a tray as described, is placed thereon.

From the foregoing description, taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art, that I have provided a practical and convenient carrier tray, for the individual reception of a plurality of s ophthalmic test lenses which will maintain the lenses in a substantially vertical antirattling position, and will space one lens from the other, in a series of parallel rows.

While I have shown and described one practical embodiment of my invention, it is to be understood, that I do not limit myself to the exact construction as set forth, but consider myself at liberty to make such changes and modifications, as fairly fall Within the scope of the appended claims.
