Applicatiomfiled February 1, 1924. Seria1.Nio. 689,869;

This inventionis a device for firmly and rigidly channel-bar members, each] having down turned ends secured. to suitable support ng elements; In. order. to bend the ends of the channelrbar. supporting members, it is f rst necessany. to, heat them and the operation,

therefore requires some little time and labor. It has also been found in practice,

that: some inconvenience is experienced in fastening the shelf tothe bracket or support, so that the shelf. will; lie perfectly flat, and

@not bind or buckle due tothe ordinary warping tendencies of thelumber.

(Dne; of theobjects of. the present inventions isltopnovide ashelf support, similar in. type to that disclosed in the application -1fQI1 patent above. identified, but Which may be; more economically manufactured and readily, substituted, therefor. A further objectis to provide a. shelf. support in which the, channeLbraeket issustained by one piece stampinga riveted to, the bracket, and having means for engaging suitable support elementssuch as-the pilasters, or the stiles of supporting; frames, as in application mentioned. A further object is to provide simple and" effective means for securing the shelyes torthe respective brackets.

It is tobe understoodhow ever, that, thisconstruction is selected, merely for illustrative purposesand the invention 1s not limited to. use inconnection there- With. a v

The shelves B are supported by carrier members-G, the ends of which. rest, upon and are secured to bracket members Di. Each carrier member consists of a body of channel iron, the-length oify which correspondstothe widthof the shelf, the flanges 15 being slotted at 116, and extending into kerfs 1? formed in theundersides of the shelves, contiguousvto their end edges. The l It is bottom, Wallor" the carrier members C is struct upwardly to, form a longitudinally disposed concavo-conven strengthening rib; 17,, )rovided,with spaced apartholes 18 contiguous to each endl.

The bracket member D is provided ,With flanges 19,,Wl1l0l1 embrace the sides of' one of the upright support nembers the device being held, in placeby means of a screw or the like, passed through, a suitableopening .20 in the body of, the, support. The upper .bers G, by passing the lugs 22- upwardly beneathtthe rib 17., andacansingthereduced:

ortions. to! protrude through the hQ1es1 a fit) whereupon they are riveted to prevent separation. In this manner the members C and D are securely united and a very rigid structure is provided.

The underside of each shelf B, contiguous to each of the kerfs 17, is provided with recesses 24 in each of which is pivotally mounted a locking member 25. constructed with a minor and a major axis. as shown. Said locking member is preferably made of thin metal having struck-up portions 26, and is retained in position by means of a screw 27. The slots 16 are so located in the bracket member C as to coincide with the recesses 21.

In practice, before the shelves are placed in position upon the shelf supports, the locking members 25 are adjusted to have their major axes aligned with the kerfs 17. Then the shelves have been placed in position upon the members C, with the flanges extending into the contiguous keris of adjoining shelves, a rotation of a latch piece on the pivoting screw, will cause an end thereof to engage the contiguous slot 16 of the supporting channel, and thus lock the shelf down to the channel. By forming each latch piece 25'witl1 a cam edge as shown, it will not only hold the shelf down, but also exert a drawing pressure as it is turned into engagement with the slot 16. The struck-up portions 26 provide ears or lugs which may be engaged by a suitable tool to assist in rotating the device.

A slight modification is illustrated in Figure 6, in which the longitudinal rib of the carrier member C is provided with a slot 30, to receive a lug 31, formed on the attaching device 32, secured to the shelf B. In practice the shelf, as it is placed in position, brings the lug 31 into register with the slot 32, so that it will pass through the latter. Said lag is then given a slight twist to bring it crosswise of the slot 30, as illustrated in dotted lines.

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. It will be particularly noted that a very rigid form of shelf support is provided, which may be more economically manufactured than the device disclosed in the application for patent above identified, and while capable of general use. may be readily substituted therefor. It will also he observed that simple and etiicient means are provided by which the shelf may be fastened to the support so as to lie perfectly flat, and also preventsubsequent buckling or warping of the shelving after it has been placed in position.

Having thus explained the nature of the invention and described an operative man- 'ner of constructing and using the same, al-

though without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1.
