Application June 21, 1949, Serial No. 100,504

9 Claims. (Cl. 211-181) This invention relates to an improved correspondence tray of the type used upon desks for holding letters and other papers which are to be mailed and it is one object of the invention to provide a tray which is formed of strong wire and of such construction that a number of trays may be stacked one upon another.

Another object of the invention is to provide the tray with side walls and supporting feet or props extending downwardly from the side Walls, the tray and the props being formed of resilient wire and portions of the wire strand from. which the props are formed serving as reinforcements for the side walls.

Another object of the invention is to so form the reinforcements that portions project upwardly from front and rear portions of the tray and are so shaped that they may cooperate with upwardly projecting portions of other reinforcements located midway the length of the tray and have firm gripping engagement with the props of another tray and firmly, but detachably, hold the upper tray in engagement with the lower tray and very effectively prevent the upper tray from slipping out of position at rest upon the lower tray.

Another object of the invention is to provide a tray of this character which is entirely formed from metal strands, and may be manufactured at low cost.

The invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a perspective view of the improved tray.

Fig. 2 is a top plan view of the tray.

Fig. 3 is a side elevation showing trays stacked one upon another.

Fig.4 is a fragmentary perspective view showing portions of the stacked trays inter-locked Fig. 5 is a vertical sectional View taken along the line 5--5 of Figure 4.

Fig. 6 is a vertical sectional view taken along the line 6-6 of Figure 4.

Fig. '7 is a view showing the upper tray til-ted to a raised position in which papers may be readily placed in or removed from the lower tray.

This improved tray has a bottom I formed entirely of metal strands, one of which has it ends soldered together, as shown at 2., and is bent to form the bottom with a stiff margin consisting .of a rear bar 3, side bars 4, and a front bar 5 which has its intermediate portion 6 bowed inwardly in a direction rearwardly of the tray toprovide the tray with a recess in order that letters and other papers placed in the tray may be readily grasped and lifted from the tray. Strands 8 extend longitudinally of the bottom in transverse spaced relation to each other and have their ends soldered to the rear bar 3 and the front bar 5 and in order to brace these rods there has been provided a cross rod or wire strand 9 which extends transversely of the tray midway the length thereof and is soldered to the side bars and to under portions of the rods 8. Another wire strand is bent to form a rear bar I0 and side bars I! which extend forwardly from the bar I!) and have forward ends bent inwardly and downwardly to form arms I2 and upon referring to Figures 1 and 3 it will be seen that this strand cooperates with the marginal strand of the bottom to form a rear wall and side walls for the tray and also form abutments or side portions of a front wall for the tray.

The rear wall of the tray is reinforced by a wire ring or brace [3 which is soldered against outer surfaces of the rear bars or rods 3 and Ill and projects upwardly from the upper bar ll! of this rear wall, and since the lower portion of the ring is soldered to the lower bar 3 in spaced relation to meeting ends of the wire strand from which the marginal portion of the bottom is formed the soldered connection for these ends will be reinforced and prevented from being broken apart.

Each of the side walls of the tray is reinforced midway its length by a ring or brace l4 which is soldered against outer surfaces of the upper and lower bars l l and 4 of the side wall and has its upper portion projecting upwardly from the upper bar of the side wall. The side walls are additionally reinforced by braces or struts I5 which are of inverted -shape, so that they taper upwardly, and have their upper portions projecting upwardly from the upper bars II of the sidewalls. Terminals of the bracesor struts I5 are bent outwardly a slight amount in order to form bills or hooks l6 and since the struts are soldered to inner surfaces of the side walls with their bills deflected outwardly over the upper bars H as shown in Figure 2, a locking action takes place when the feet or supports of a second tray are forced downwardly against the upper bars of the first tray, thus firmly, but detachably, holding a tray at rest upon another tray.

The feet or supports I! for the tray are each formed from a metal strand which extends 1ongitudinally of the tray under a side wall thereof. Portions of the wire strands from which the supports are formed are bent upwardly to form arimfi fi 6 Which are soldered to the side bars of the bottom of the tray, and from an inspection of Figures 1 and 3 it will be seen that these portion of the strands extend upwardly from the bottom of the tray and are bent to form the braces or struts ['5 and their bills Hi. Therefore the supports or feet will be very firmly mounted and can not easily become detached from the tray.

When a tray of the improved construction is in use it i placed upon a desk or table where it is supported in an elevated position by its supports and another tray of duplicate construction shifted downwardly they may be easily moved into position to rest upon the upper bars of the side walls of the lower tray with clips formed by the upwardly projection positions of the rings [4 and the struts IS in frictional gripping en gagement with side portions of the supports and the bills of the struts in overlying engagement with their upper surfaces and it will be impossible for the upper tray to accidently slip out of its proper position at rest upon the lower tray. It

should also be noted that since the supports hold the trays in an elevated position the bottom of the upper tray will be spaced upwardly from the lower tray such a distance that letters and papers may be easily thrust into or removed from the bottom tray without interference by the upper tray. When the trays are to be separated it is merely necessary to grasp the lower tray and exert upward pull upon the upper tray and the support for the upper tray will be moved upwardly out of engagement with the rings l4 and the bills or hooks of the props of the lower tray.

In Fig. 7 there has been shown a pair of trays disposed one above the other, the upper tray having its support I! at one side resting upon the upper bar of the side wall at the corresponding side of the lower tray and the other side of the upper tray free from the lower tray. Ordinarily the supports of the upper tray are both at rest upon the upper bar H of the side walls of the lower tray and gripped by the jaws formed by the protruding upper clip portions of the braces l4 and I and when a large number of letters 01' files are deposited in the lower tray, and project upwardly above its side walls, it is difiicult to place other letters or files in the lower tray or remove them. The support at either side of the upper tray may then be released from the wall of the lower tray, and as the support at the other side of the upper tray remains in engagement with the lower tray it forms a hinged connection between the trays and the upper tray may be swung upwardly to a transversely tilted position. Letters or files may then be readily placed in or removed from the lower tray and the upper tray returned to its original position in which both of its supports I! are gripped and the upper tray secured along both sides and firmly held in engagement with the lower tray.

Having thus described the invention, what is claimed is:

1.
