JOHN D. SPAULDING AND OLIVER D. COLLIS, OF CLINTON, IOWAQASSIGNORS TO THE COLLIS COMPANY, OECLIN'I'ON,

V GRATING.
Application filed January To all whom it may concern Be it known that we, JOHN D. SIAULDING and OLIVER D. CoLLIs, both citizens of the United States, and residing at Clinton, county of Clinton, and State of Iowa, have invented certain new and useful Improvements in Gratings, of which the following is a specification.
This invention is intended primarily as a grating or shelf for use in connection with bread racks or like structures in which an openwork shelving is desirable, and the object of the present invention is to simplify the construction and cost of manufacture without sacrificing the elements of strength, rigidity, and durability. The grating or shelf consists essentially of a series of cross rails or bars with wire rods running at right angles thereto. In the past it has been customar in the manufacture of such gratcontinuous length of wire bent back and forth upon itself, which method of manufacture has involved difliculties and complications in the handling of such a continuous length of Wire, which difficulties are avoided in the case of the present invention.
The employment of a continuous length of wire renders it diflicult to repair or renew any of the rod sections in case the same becomes broken. The present invention also obviates this difficulty by arranging the sections in units which, in case of breakage, may be renewed individually without difficulty.
Further objects and details of the invention will appear from the specification wherein- Figure 1 is a perspective view of a section of the present grating or shelf prior to galvanizing;
Fig. 2 is a detail partly in section showing the method of overlapping the ends of the wire rod after the same has been com pleted by a galvanizing process;
Fig. 3 is a perspective showing the method of clamping .an intermediate section of the wire rod to the rail before galvanizing; and
Figs. 4 and 5 are details partly in section showing modified methods of forming and overlapping the ends of the Wire rods, completed -by galvanizing.
The grating as a whole comprlses a plurality of spaced parallel side rails 10 each so, 1925. Serial in). 5,700.
relation, which side rails are connected by means of a plurality of parallel cross rails 11 eachterminatin in a dowel 12 of re duced dimension w ich isentered through the side rails and upset to rivet the parts together. The structure comprises a frame for the support of a plurality of cross rods 13 which are arranged in pairs forming closed units of elongated rectangular formation being connected by end sections 1 1-14 which have turns lying outside of the margmal cross rails 11. It will be understood that the number of cross rails may be multiplied indefinitely, and in the present instance three only of said cross rails are shown simply byway of illustration.
At the pointswhere the rods 13 intersect the cross rails, the latter are provided with recesses 15 into which the rods are laid after .which the edges of said recesses are struck or swedged down to form overlapping lips 16 which serve to tightly embrace and hold the rods in place. The arrangement is one which brings the ends of the cross rods into overlapping relation with respect to one of the cross bars which, in the present instance, is shown to be the intermediate cross bar. In Figs. land 2, the recesses 17 which receive the overlapped ends of the rods are of double depth, but are otherwise similar in formation to the recesses 15 already described.
In providing the overlap for the ends of the wlre rods, the preferred method is that shown in Fig. 2, in which one of the ends 18 is given an abrupt offset to bring it underneath the end of the companion rod, which arrangement limits the bent or offset to a point closely adjacent the cross bar, so thatafter the entire grating hasbeen dipped into a galvanizing bath, a deposit 19 of zinc or like galvanizing metal will fill into the interstices and corners adjacent to the overlapped ends of the rods, so that the joint at this point will be practically sealed and diflicult of detection and the entire grating or shelf will be protected by the galvanizing coat.
In Fig. 4 the ends 2020 of the rods are half out in each instance, so that a similar result is attained, while in Fig. 5 the ends 2l--21 are each beveledto provide for an overlap, although the construction of Fig. 2 is preferred, since it does not weaken the formed from a bar of metal set in edgewise structure by cutting. away the stock. Of
course, in the case of Figs. 4 and 5, it is unnecessary to provide a recess of double depth to receive the overlapped ends of the wire.
The arrangement is one which permits the cross rods to be made in units and inserted into place by easy manipulation, or by mechanlcal means, and avolds the diiiiculty attendant the employment of a continuous length of wire running back and forth throughout the entire series of rods. at the same time the arrangement is one which is to all intents and purposes as strong and rigid as though a continuous wire were emplo ed.
