1955 c. c. AVERILL- STACKABLE WIRE CRATE Filed Nov. 15, 1952 United States Patent STACKABIJE WIRE CRATE Charles C. Averill, Albion, Mich, assignor to Union Steel Products Company, Albion, *Mich a corporation of Michigan Application November 15, 1952, Serial No. 320,663

8 Claims. .(Cl. 220-719) This invention relates to improvements in a stackable wire crate.

The main objects of this invention are:

First, to provide a-metal crate in which the receptacle proper may be formed of relatively'light wire stock and is supported and guarded by .a base which renders the structure capable of withstanding rough .usage. 7

Second, to provide a metal crate comprising a receptacle and a base in which the receptacle and the'base may be formed as separate units and assembled into a unitary structure thereby greatly facilitating the manufacture.

Third, to provide a crate which may be be effectively handled on conveyors and slid or drawn about on a floor, deck or platform withoutserious injury thereto.

Fourth, to provide a crate .having these advantages which may be economically produced, both in the matter of material and the assembling thereof.

Objects relating to details and economies of the .invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is an elevational view of a crate embodying my invention.

Fig. 2 is an enlarged fragmentary vertical :section on a line corresponding to line 2-2 of Fig. 1, illustrating a pair of crates in stacked relation.

Fig. 3 is an elevational view of :the receptacle unit.

Fig. 4 is an elevational view of the base unit.

Fig. 5 is a plan view of the base .unit.

The .crate .of my invention is adapted for a wide variety of uses, one of them being a crate for .milk and the like but I have not illustrated partitions therein as they form no part of my present invention and further, the crate is, as stated, adapted for many uses such as handling produce and for materials in shops, factories and the like.

The embodiment of my invention illustrated comprises a receptacle designated generally by the numeral 1 and a base designated generally by the numeral 2. The receptacle and base are fabricated as separate units and then assembled as will hereinafter be pointed out.

The receptacle 1 comprises vertically spaced horizontal frame members 3, 4 and 5 formed \of wire or light rod stock. I provide sets of U-shaped side wall and bottom slat members 6 including integral side wallslats 7 and bottom slats 8. The side wall slats are arranged on the inner sides of the frame members and fixedly "secured thereto as by welding indicated .at 9 in Fig. 2. The slat members 6 are disposed with their bottom slats 8 in crossing relation and-fixedly secured at'theircrossing points as by welding indicated at 10. The set of slats, the bottom slats of which are superimposed on the other bottom slats, is preferably formed of wire of fiatsection as is illustrated. The framemember'3 constitutes the top border frame-or rim-.ofthereceptacle.

The base comprises the border frame :11 of shape and dimensions approximately that of the top frame 3. The base cross members 12 are desirably of a gauge of stock substantially exceeding that of the base border frame and have upwardly offset ends 13 lapped upon the top of and welded at 14 to opposite members of the base frame. Angled corner members 15 are disposed in vertically aligned spaced relation to the base frame and have downturned ends 16 fixedly secured to the top of the base border frame, desirably by welding as indicated at 17.

The annular shoe 18 is of the same shape as the base frame, the corresponding sides thereof being spaced inwardly from the base frame as illustrated. This shoe is welded as indicated at 19 to the under sides of the base crosspieces 12 and constitutes a direct support for the crate when it is carried along on a conveyor or is dragged or slid along on the 'floor, platform or deck. The shoe 18 is desirably of a heavier gauge stock than the base frame 11 and constitutes a supporting member and a reinforcing element for the base.

After the base and the receptacle are assembled, the assembled receptacle is placed upon the base within the cornermembers and fixedly secured to the crosspieces of the base, desirably by welding as is indicated at 20. The corner members are substantially spaced from the base border frame and they are of substantial length so that they embrace a plurality of both sets of slats at the corners of -the receptacle. When one receptacle is stacked upon another, the shoe 18 of a superimposed crate is positioned within the top border frame of the adjacent lower crate and they thus serve as stacking members, preventing the upper crates from sliding oif the lower crates.

In the manufacture of the receptacle, the sets of bottom and side slat members may be disposed in the fiat in .crossed relation and welded together at their crossing .points. The side wall slat portions are then bent upwardly and the frame members 3, 4 and 5 welded thereto with the frame member .3 constituting the top 'frame ofthe receptacle.

'In assembling the base, the border frame 11, cross members 12 and the shoe 18 may be placed ina suit able jig and welded into assembled relation. The corner members 16 may then be welded imposition.

The crate of my invention is capable of withstanding very severe usage. The metal crates of this general type are roughly handled and even frequently thrown or tossed about. The crossing slats are also desirably welded to the corner members. The shoe receives the wear when the crate -is dragged about and it also provides a stable base when the crate is conveyed by a conveyor of the roller type.

.I have illustrated anddescribed my invention in a practical commercial embodiment thereof. I have not attempted to illustrate or describe other adaptations which Icontemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may bedesired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
