ONE-PIECE SHEET METAL TRAY CONSTRUCTION Filed Sept. 26, 1952 2 Sheets-Sheet 2 $2 3 Chaz'zes O. Larson 2,739,728 ONE-PIECE SHEET METAL TRAY CONSTRUCTION Charles 0. Larson, Sterling, Ill., assignor to Chas. O. Larson Company, Sterling, 111., a corporation of Illinois This invention relates to a new and improved onepiece sheet metal tray construction, especially designed and adapted for use in shops and other places, in which to keep small tools and the like, but suitable for various other uses.

'The principal object is to provide a tray construction of the kind mentioned that is simple and economical to manufacture and adapted to be fastened to the wall easily using only one screw or nail at each end, the construction being such that the tray will nevertheless be quite rigid and sturdy.

A salient feature of the present tray construction is theprovision of integral end walls that are struck on an are at the front lower edge to conform to the curvature of the bottom of the trough-shaped body portion for neatness in appearance, these end walls having the rear portion cut otf square for locating and supporting engagement 'with the wall on which the tray is mounted.

Another important feature is the provision of inturned flanges on the rear portion of the end walls arranged to be overlapped by the top rear corners of the troughshaped body portion of the tray and secured in such relationship by the nails or screws that are entered through registering holes provided in these abutting portions, the nails or screws, one at each end of the tray, serving to fasten the tray to the wall for support.

The invention is illustrated in the accompanying drawings, in which- Figs. 1 to 3 are perspective views of trays made in accordance with my invention, shown as being made in graduated sizes to accommodate different sizes of small tools;

Fig. 4 is an end view of one of these trays;

Fig. 5 is a top view of the same tray; and

Fig. 6 shows the flat sheet metal blank from which the tray of Figs. 4 and 5 is formed.

The same reference numerals are applied to corresponding parts throughout these views.

Referring first to Figs. 4 to 6, the sheet metal blank 10 shown in Fig. 6 comprises a rectangular main middle portion 11 on the opposite ends of which are integral extensions 12 and 13 that are also generally rectangular in form except for the arcuate edges 14 on the inner ends of these extensions next to the narrow connecting webs 15. This blank is punched from the flat sheet and requires only the bending of the rectangular main middle portion 11 into a trough shape, as indicated at 16 in Fig. 4, and the bending of the extensions 12 and 13 at the webs 15 into parallelism to provide end walls 17 and 18 for the tray, the arcuate edges 14 conforming nicely. to the curvature of the bottom of the trough 16 throughapproximately 90, as clearly illustrated in Fig. 4. While I prefer, for the sake of economy, to leave the ends 17 and 18 free, they could easily be soldered or welded to the trough 16 along the edges 14. The end walls 17 and 18 are shown as held in abutment with the ends of the trough-shaped body 16 by means of the end portions 19 and 20 of the extensions 12 and 13, the portions 19 and 20 being bent at right angles toward one another on the lines a-b and c'd toifprovide the flanges 21 and 22 which serve teprovide locating and supporting engagement with the wall indicated at W in Fig. 4. These flanges 21 and 22 are overlapped by the top rear corner portions 23 and 24 ofthe trough-shaped body 16 and there are registering holes in theseabutting portions, as indicated at 25 and 26, through'which nails or screws can be entered to hold'the end walls 17 and 18 of the tray in assembled abutting relation to the ends of the trough-shaped body 16 and atthe sametime fasten the tray to the wall W for support. In the present case screws 27 are illustrated forthis purpose.

It is'clear from the above description that I have pro vided a one-piece sheet metal tray construction that is simpleand economical to manufacture and will find many uses in shops and other places for'the handy storage of small tools and other articles. For example, the smallest size tray A illustrated in'Fig. I. is adapted to receive a full set of sockets 28 of graduated sizes for a socket wrench set, enabling the keeping of these sockets in an orderly fashion for the quicker selectionflof the particular size needed. The next larger sizeftray B, illustrated in Fig.

2, islargeenoughto accommodate the wrench 29, and the next larger tray 0, illustrated in Fig. 3, will accommodate other tools 30. The tray B corresponds to that illustrated in Figs- 4 and 5 but ineach instance the same construction is employed and hence the same reference numerals are applied to designate the trough-shaped body 16, opposed end , walls 17 and 18, inturned flanges 21 and 22, and so on.

It is believed the foregoingdescription conveys a good understanding or .the objects and advantages of my invention. The appended claims have been drawn to cover all legitimatemodifications and adaptations.
