To all whom. it may concern Be it known that I, EDMUND KANDLER, a

citizen of the United States, residing at Rochester, in the county of Monroe and of an ophthalmic test lens set, such as are employed by Opticians in testing the. irefractive properties of a patients eyes preparatory to fitting eyeglasses. The object of the invention is to provide a sanitary tray for ophthalmic test lenses, and is a division of my pending application Serial No. 144,351, filed January 25, 1917. To these and other ends the invention consists in certain improvements and combinations .of parts, all as will be hereinafter more fully described, the novel features being pointed out iir-the claims at the end of the specification.

In the drawings:

Figure 1 is a plan view of a testlens tray constructed in accordance with my inven tion;

Fig. 2 is a transverse sectional view of the device shown in Fig. 1; I

Fig. 3 isan enlarged perspective view of one of the inner channel partitionsof the tray, one end being broken away and showing the plate partitions mounted thereon;

Fig. 4: is a longitudinal sectional view partly broken away and taken along the face of a plate partition;

Fig. 5 is a perspective view of one of the corner members of the frame, and

Fig. 6 is a similar view of the same in another position. 1

Similar reference numerals in the several figures indicate the same parts.

My improved test lens tray may be made of any form and of any size required to include the requisite number of narrow lens chambers 1, which may receive comparatively thin spherical and cylindrical lenses, and a comparatively few, say four, wider chambers 2 which may receive thicker pris matic lenses. The frame of the tray comi i Specificationof Letters Fatent.

prises two sheet metal channel end portions 3 andB and front and rear sheet metal channel frame portions 45'? and 4:. At the adjacent ends of the frame and end pore tions, or the corners of the frame, the adjacentiends of the

members

3, 3 and 4, l? are. connected by means of sheet metal corner members 5, shown in Figs. 5 and 6, struckup tofit, into the ends of the The frame, when assembled inthismanner, presents a pleasing. smoothappearance with round corners and possesses the qualities of lightness, rigidity and durability. M l

In the construction illustrated, the lens chambers 1 and2are entirely open at the top and only slightly obstructed at thebottom." Said chambersare formed by a series or plurality of substantially parallelinner metal channel partitions 6 of whichseven are illustrated in the drawings, and two

end frame portions

3 and 3, also substantially parallel therewith. The spacesformed between the members 3,-3* 6, 4 and 45 are subdivided by a series or plurality of flat sheet metal plates substantially parallel with the

frame members

4 and 4? into a series or plurality of chambers 1 and2, described above,

The partitions 6 are spaced substantially equidistant from each other and from the end frame members .3 and 3, forming a series or plurality of substantially parallel elongated chambers, each of which is subdivided by the plates 7 into a series or plurality of lens chambers or cells 1, 2. The sheet

metal frame portions

3, 3 4, and 1* are struck up from sheet metal substantially U-shaped in cross section. The open sides of the frame portions 4 and 1 are directed.

inwardly, and those of the

portions

3 and 3 iare directed downwardly. The ends of the plates 7 extend into slots formed in the side walls of the

members

3 and 3 and are inclined rearwardly from the vertical, so that they assume a substantially vertical position when the tray is tilted forwardly.

The channel partitions are provided with a plurality of closed slots corresponding to the slots in the

frame members

3 and 3 Said slots 8 are inclined to correspond to the inclinationof the partitionplates 7 which extend through the slots and are supported in the channelpartitions. It will be noted that only the inner walls of the

frame members

3 and 3 are provided with slots through which the ends of the plates extend and are, housed therein. The slots 8 are also spaced to correspond to the spacing of the plates 7 which they support.

A Wire or light rod 9 extends through each row of cells or chambers near its bottom and is supported in the plates 7 by extending through openings provided therefor in the plates. The rods or Wires 9 serve as light and convenient supports for the test lenses in the cells.

Practically all portions of this improved test lens tray may be made of metal, celluloid, or other tough, readily cleansable material. Since the lens cells or chambers are entirely open at the top and are only slightly obstructed at the bottom by the lens retaining Wires, it is obvious that it may be readily cleansed by pouring upon and through it antiseptic fluids, or it may be immersed in a bath of such fluid or boiling Water and thus at all times be kept thoroughly sterilized for safe use.

I claim as my invention:

1. An ophthalmic test lens tray comprising a frame, an inverted substantially U- shaped channel partition extending across said frame and having its Walls provided with a plurality of closed slots, a plurality of plate partitions extending through said slots and supported by the channel partition and forming therewith a series of lens cells, means for supporting lenses in said cells.

2. An ophthalmic test lens tray embodying channel partitions and plate partitions supported thereby and together forming aplurality of lens chambers open through from top to bottom, means for retaining .lenses in said chambers, and a marginal frame for the partitions including an outer ing means, and a pair of channel bars ranglng parallel to the plate partitions and -joined to the outer channel partitions.

3. An ophthalmic test lens tray embodying channel partitions, plate partitions supported thereby and together forming a plurality of lens chambers open through from top' to bottom, means for retaining the lenses in the chambers, and a marginal finishing frame comprising front and rear bars, and opposite end channel bars secured to the front and rear frame bars and slotted at their inner flanges and receiving the ends of the plate partitions in said slots.

a. An ophthalmic test lens tray comprising a pair of substantially parallel frame members, a pair of substantially inverted U-shaped end frame members extending between the ends of the first mentioned frame members, a plurality of substantially inverted U-shaped channel partitions having their ends secured in said first mentioned frame members and extending therebetween in substantially parallel relation to said end frame members, each of said U- shaped members being provided with a plurality of substantially parallel closed slots, a plurality of plate partitions extending across said frame and supported in said slots and forming a plurality of lens cells with the frame and channel members, and means for supporting lenses in said cells.
