Patented July 22, 1947 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to trays, such as, drain? age trays used for holding newly washed dishes.

An object of the present invention is to provide a foraminous tray embodying alternate openings and supports for supporting dishes or the like, which tray is constructd of a plurality of gridiron-like panels of molded thermo-plastic cemented together by a suitable cement to form a practical appearing tray which will not roughen, corrode, or scratch any surface upon which it is placed.

Another object of the invention is to provide a tray as specified which is fabricated from gridiron-like panels all of the same size and shape, certain of which are shaped to form the sides of the tray, while others are shaped to form the ends of the tray, thereby permitting production molding of the panels with a single set of dies of much simpler construction and greatly reduced cost than of dies which would be required to mold a complete, or practically complete, tray in a single molding operation.

With these and other objects in view, as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing a tray of a preferred form embodying the invention, and the features forming the invention will be specifically pointed out in the claims.

In the drawings:

Figure 1 is a side elevation of the tray;

Figure 2 is a top plan of the tray;

Figure 3 is an end elevation of the tray;

Figure 4 is a cross-section through the tray taken on the line 44 of Figure 2.;

Figure 5 is an enlarged detail cross-section taken on the line 5-5 of Figure 2;

Figure 6 is a detail section taken on the line 6-6 of Figure 3;

Figure 7 is a fragmentary perspective view of a part of one of the panels;

Figure 8 is a perspective view of one of the panels prior toits shaping to form its part of the tray; and

Figure 9 is a detail section corresponding to the section shown in Figure 5, but showing a slight modification of the tray structure.

Referring more particularly to the drawings, the improved tray which is rectangular in shape is formed of a plurality of molded panels I of thermo-plastic. One such panel, as it comes from the molding machine and prior to being shaped to form its respective part of the tray, is shown in Figure 8 of the drawings. The panel I comprises the sides 2, ends 3, and a series of parallel cross bars 4, all molded into a single unitary shape and forming a gridiron-like panel. The sides 2, ends 3, and cross bars or ribs 4 all have right angularly extending reinforcing flanges 5 formed thereon which strengthen the panel and increase its rigidity.

The panel of which the central portion of the bottom of the tray is formed, namely, the panel I1], is, after it is taken from the molding machine, heated and shaped to provide upwardly extending supporting sections ll against which dishes may lean for support in the tray. The sides of the tray are formed of panels !2 which are identical in their initial molded state to the panel I. The panels l2 are, after they come from the molding machine, heated and are shaped to provide the bottom forming portions l4 and the sides [5 which extend at right angles to the bottomforming portions I 4. The connecting portions between the horizontal portion 14 and the vertical portions l5 are rounded and clip, as clearly shown at iii in Figures 3 and 4 of the'drawings, thus providing rounded corners for the tray and supporting portions which will contact the support upon which the tray, when finished, is placed, thereby preventing the bottom of the tray from contacting the surface upon which the tray is placed and permitting free drainage of water from the dishes held by the tray.

The meeting longitudinal edges of the central panel In and the side-forming panels [2 overlap, as clearly shown in Figure 5 of the drawings, and these overlapping edges are cemented one to the other by suitable cement, such as an acetate cement, so as to firmly and rigidly connect the panels forming the sides and bottom of the tray together. By overlapping the meeting edges of the panels l0 and i2, the completed tray is rendered sturdy and more rigid.

One of the panels, as shown in Figure 8, is cut longitudinally to form one end of the tray, and this panel I! is cemented by suitable cement to the ends of the side panels I2 and one end of the central bottom-forming panel ID with its side 2 forming the top of the tray, while the free ends of the cut cross bars 4 are in the same plane as the lowermost portions of the curved dipped portions it of the side-forming panels I2 so as to provide additional surface-contactin supports for the tray. 7

One of the panels, namely, the panel l8 which forms the end of the tray opposite to the one iqlmed by the cut panel I! is shaped or curved intermediate its sides to form a manger-like article support exterior of the main body of the tray, as clearly shown in Figure 1 of the drawings. This end forming panel I 8 has a part H) which forms the end of the tray fiat and is cemented to the ends of the panels l and I2 opposite to the ends of these members to which the cut panel IT is cemented. The panel I8 is heated and formed over any suitable type of mandrel to provide the curved portion connecting the straight portion l9 and the substantially straight outer side portion 20 of the panel I8 so as to provide the dipped or manger-like support on which knives, forks, spoons, or other articles may be placed for drainmg.

In Figure 9 of the drawings, a slight modification of the invention is shown, and in this figure, the sides of the panel it) which form the central portion of the bottom of the tray abut against right angularly extending sides 2 of the panels l2 which form the side portions of the bottom and the sides of the tray, instead of being in overlapping relation as shown in Figure 5. These abutting surfaces are cemented one to the other. It is to be understood in the cementing of the various sections and various panels to each other that they may overlap or abut, as desired, without departing from the spirit of the present invention.

The cut cross bars 4 of the panel ll which is cut to form one end of the tray abut and are cemented to the ends 3 of the panel I U and the panels I2, as clearly shown in Figure 6 of the drawings.

While in the drawings and in the foregoing description the tray is shown and described as particularly adapted for holding dishes and/or silverware for draining, it is to be understood that the improved tray may be used for any suitable purpose and that the present invention comprehends the novel feature of forming a foraminous tray of a plurality of identical panels of molded thermo-plastic which are shaped after molding to form the various parts of the tray and are then cemented together to provide the complete tray.

The trays, being made of thermo-plastic material, may be made in any desired color, will have an attractive sheen, and, owing to the nature of the thermo-plastic material, will not scratch or mar silverware, dishes, or any other articles supported by the trays.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown, but that they may be widely modified within the invention defined by the claims.
