Claims.

The main object of this invention is to provide a metal or a so-called wire shelf for refrigerators, ovens, and like purposes which presents a smooth surface at its front end so that objects 5 may be slid upon or placed upon the shelf without'catching and without injury to such objects, as cartons, bags, paper wrappers, and the like.

A further object is to provide a structure having these advantages which is very strong and rigid and at the same time one which is economically produced.

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

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

Fig. l is a fragmentary side elevation of a re- 20 frigerator with the wall partially broken away i and sectioned and the door open showing my improved shelves in a position for use therein, the parts being mainly shown in conventional form.

Fig. 2 is a plan view of my improved shelf.

Fig. 3 is a sectional view from front to rear on a line corresponding to line 3-3 ,of Fig. 2.

;Fig. 4 is an enlarged detail view partially in section on line 44 of Fig. 2.' A Fig. 5 is an enlarged detail view partially in section on line 5-5 of. Fig. 2.

Fig. 6 is an enlarged detail view partially section on line 66 of Fig. 2.

Fig. 7 is a fragmentary view partially in sec- 35 tion on line of Fig. 2.

In theaccompanying drawing, i represents a refrigerator cabinet, 2 the door thereof, and 3 the shelf supporting members. My improved shelf is especially designed by me for use in re- 40 frigerators, ovens and the like where it is necessary to frequently place articles upon or remove them from the rack. These articles are inserted from the front of the refrigerator or oven and commonly placed upon the rack with a sliding or horizontal movement and frequently are slid upon the rack.

My improved rack designated generally by the numeral 4, comprises a rectangular border frame designated generally by the numeral 5 formed of rod material or stock preferably of cylindrical cross section as illustrated. This frame comprises a front member 6, a. rear member i, and end members 8, and it is preferably endless; that is, formed of a piece of rod bent into proper shape with the ends butt-welded together as indicated at 9.

The intermediate bar I0, also formed of round rod or heavy wire stock, is disposed with. its ends abutting the inner sides of the border frame end members and butt-welded thereto as best shown in Fig. 7. It will-be noted that the tops of this transverse cross rod or intermediate rod or bar is substantially below the plane of the tops of the end members 8 of the border frame. The butt or T-weld for this transverse or intermediate bar to the end members is indicated at I i.

The slats ii are formed of wire and are disposed with their rear ends in superimposed relation to the rear border frame member and welded thereto, as indicated at l3. They are also disposed in crossing superimposed relation to the bar it and welded thereto, as indicated at M. Their front ends are disposed in abutting relation to the inner side of the front frame member 6 and are butt or T-welded thereto asindicated at it.

It will be noted by reference to Fig.4 that the front ends it of the slats are in a plane slightly below the plane of the top of the front frame member so that the front frame member, provides a rounded guiding surface over which articlesmay he slid onto the slats. The positioning of the cross member it! below the planes of the tops of the end members of the frame permits this arrangement of the slats with their rear ends superimposed upon and welded to the rear member of the frame and their being superimposed upon and welded to the intermediate ,1. frame member without bowing the slats, which would be objectionable, as it would provide an unstable support for the articles placed thereon,

and a teetering'movement such as would result from curved or bowed slats would be very objectionable in a refrigerator or oven.

A further advantage of providing a guard and rounded guiding surface for the front ends of the slats is that cartons and bags or paper wrap pers are not likely to be torn and opened, as is likely to result when the slats are arranged at the front end of the rack, as are the rear ends of the slats of applicant's structure, so that they project, as clearly indicated in Fig. 6.

I have shown the slats as being-of round wire or of cylindrical section, but fiat wire or slats of flat section may be used and for some purposes may be preferred. My improved rack has the advantages of being strong and rigid and very economical to produce, attractive in appearance, and there are no projections at the front of the I have illustrated my improvements as embodied in a refrigerator rack and an oven rack would be substantially thesame. attempted to illustrate or describe other embodiments or adaptations such 'as showcases or other shelving, as it is believed that this disclosure wili formed of rod material of cylindrical cross secrod material of cylindrical cross tion and comprising integral front, rear and end members, an intermediate bar having its ends butt-welded to the inner sides of the end members of said frame with the top of said intermediate bar in a plane below the plane of thetop sides of the end members and parallel wire slats having their rear ends disposed upon and welded to the top of the rear frame member and their front ends butt-welded to the inner side of the the tops of the slats front frame member with. at the front ends below the top of the front frame member and so that the front frame member constitutes a rounded guiding surface leading to the slats, the slats being superimposed upon and welded to the intermediate bar and being substantially straight and sloping slightly downwardly from rear to front.
