Specification of Letters Patent. Patenijgd Sept, 14, 1g15,

Application filed September 14, 1914. Serial No. 861,615.

To all whom it may concern Be it known that I, Anonsrus A. CARTER, a citizen of the United'States, residing at rayette, in the county of liayette and State In the accompanying illustration, I have shown a single upright standard 1 which may be of any necessary height and dimen sions, said standard being here shown as of Iowa, have invented certain new and constructed of a single strip of metal bent useful Improvements in Adjustable Shelv- 0 f rm l 11pIlgl1l3 channel shaped meming; and I do d clar th followi g to b her whose side flanges or strips 2 are proa full, clear, and exact, description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in supports and more particularly to adjustable shelving.

The main object of the invention is to provide an extremely simple structure whereby a single shelf or a plurality of shelves may be supported in vertically adjustable position.

In carrying out the above'end, a further object of the invention becomes to form the shelf of a single piece of sheet metal and to provide the same with a gripping yoke designed to embrace a vertical standard whereby to retain the shelf in adjusted position.

A still further object is to soposition the yoke as to allowthe same to grip the standard when the shelf is in normal position and to release its grip upon said standard when the shelf is swung upwardly, thereby allowing said shelf to be adjusted vertically.

Yet another object is to form the shelf proper, its gripping yoke, and a depending bracing flange of a single piece of sheet metal, the flange being struck downwardly from a portion of the sheet metal plate whereby to simultaneously form the yoke.

With the above and minor objects in view, the invention resides in certain novel features of construction and combination here in described and claimed and shown in the drawings wherein:

Figure 1 is a side elevation of a standard and a pair of shelves thereon, constructed in accordance with my invention; Fig. 2 is a front elevation with the parts as seen in bi 1' Fi 3 is a vertical'section as seen on the line 3-3 of Fig. 2, one of the shelves being swung upwardly whereby to release its gripping yoke; Fig. 4: is a horizontal section as seen on the line 4-4 of'Fig. 1, lookingin the direction of the arrows; Fig. 5 is a perspective view of one of the shelves illustrated in the previously described figures, and Fig. 6 is'a plan view of a different form of shelf.

floor or other suitable support. By reference to the drawings, it will be seen that the front strip of the standard whose upright edges are integrally joined to the front edges of the side strips 2, is of less length than said side. strips, this construction being preferable although not essential.

By constructing the standard as above described, it will be seen that the same may be easily and cheaply manufactured since but one sheet of metal plate is required for the standard and the operation of constructing said standards is very simple. I may here explain that any number of straight or arcuate rows of standards 1 may be employed and that the shelves, to be described, which are adjustably mounted on said standards may be used for supporting any articles whatever, the type of shelf shown in the present instance, being more particularly designed for supporting bolts of ribbon indicated at R in Fig. 1 (see dotted lines.)

.The above mentioned shelves are designated in the drawings by the reference numeral 10 and are here shown as formed of single non-resilient substantially rectangular sheet metal plates whose rear edge portions incline upwardly and rearwardly to form rigid flat substantially rectangular yoke plates, which latter are provided with rectangular openings 11 whereby to form inclined rigid gripping yokes 12. The openings 11 are formed by slitting the side edge portions ofeach yoke plate rearwardly and longitudinally from its front edge to points near its rear edge, by then slitting the body of said plate transversely from a point between the ends of one longitudinal slit to such a point between the ends of the other longitudinal slit, and by striking the metal from the two sides of the transverse slit downwardly to provide bracing flanges 13 which depend from the rear edge of the shelves and to likewise form reinforcing flanges 13 which are bent into contactwith the cross bars 14: of the yokes 112.

The-shelves, as above described, are p0,-

v sitioned' upon the standards 1 by swinging said shelvesto the position seen at the top of Fig. 3, in which position the yoke 12 may be end of Fig. 3, thereby causing the inner adjacent edges of the flanges 13 and the. bars 'l l'to' engage the teeth 3 on the standards while the depending bracing flanges 13 contact with the forward sides of the standards thereby effectually retaining the shelves in i their adjusted position.

In Fig. 6, I have shown a top plan view of a different form of shelf 10 which is of greater length than the shelves 10 and which is provided with gripping yokes 12 on its rear edge, one yokebeing located at each end of the shelf; It will be understood that the yokes 12 are constructed in the-same manner as yokes previously, described and that thesam'e are designed to embrace standards identical with the standards 1 previously described.- l V V Having thus described my invention, what I claimgis; I, l I

1'. A device of the class described formed of a single substantially rectangular nonresilient sheet metal plate, and comprising a flat substantially rectangular horizontal .shelf plate, and a flat substantially rectalr' gular yoke plate inclined upwardly and rearwardly from the rear edge of the shelf plate and having its front edge integrally joined thereto, the side edge portions of said yoke plate being slit rearwardly and longitudinally from the front edge of said plate, to points near the rear edge thereof, and the body of said yoke plate being slit transversely from a point between the ends of one longitudinal slit to such a point between the ends of the other longitudinal slit,

the metal in advance of the transverse slit being bent downwardly at right angles to the shelf plate to provide an upright bracing flange, and the metal in rear of said slit being folded downwardly and rearwardly upon the rear edge portion of the yoke plate to reinforce the same.

2. The combination with a vertically adjustable shelf having a laterally extending yoke, of a pair of upright parallel rigid side strips having their flat sides spaced from each other, attaching feet formed integrally with the lower ends of said plates and extending laterally therefrom, teeth on the rear edges of said strips, and an additional upright strip having its upright edges formed integrally with the front edges of the aforesaid strips, the three strips constituting an upright standard to be embraced by the yoke.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
