i A CORPORATION OF NEW YORK SUPPORT FOR snnnvns nun THE LIKE Application filed February iti, 1928 Serial- No. 253,323.

This invention relates to supports for shelves and the like. One of the objects there of is to provide an adjustable support of-the' above nature which is securely held in the position to which it is adjusted. Another obj ect is to provide a construction of the abovenature which is held firmly against displacement by an accidental blow thereon and against tendencies to be displaced when the shelf is being removed or placed in position. Another object is to provide a construction of the above nature which is simple and thoroughly dependable. Another object is to provide a construction of the above nature which is inexpensive to manufacture. Other objects will be in part obvious or in part pointed out hereinafter. v i

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.

7 In the accompanying drawings which show one or more of the various possible embodiments ofthe features of this invention,

in Figure 5,

Figure 6 is a top view of the parts shown Figure 7 is a detail view showing a moditied construction in one part ofthe structure, and

Figure 8 is a rear view of the parts shown in Figure 7.

Similar reference characters refer to similar parts throughout the several views of the elongated shape which is adapted to be secured in upright or vertical position against stamped from sheet metal and is of channel shape or U-shaped, having side flanges 10a and 10?), the edges of which rest agamst the wall 11 and which hold the front wall of the member outwardly in spaced relation to the surface of the wall against which it is secured. As shown herein, the member 10 is provided with a hole adjacent each end to receive securing devices such as screws 12 for fastening the member in place. I

In the front wall of the member 10 are a plurality of spaced openings or slots which may be said to be of keyhole shape, the slots having relatively'wide upper portions and relatively narrow lower portions. Exterior of the member 10 is a supporting member having two parts bent substantially at right angles to each other, a vertical part 13 and an outwardly horizontally extending part 14. The part 13 is adapted to rest against the outer surface of themember 10 and the outwardly projecting part 14 supports the shelf member 15 or other device to be supported by this construction. As shown in Fi ure 1, the

outer end ofthe part 14 has pre erably an cent the outer end of the part 14 is a bracing rod 16. As shown in Figure 3 the end of the rod 16 passes through an opening in the part 13 and is threaded, having thereon. a nut 17 exterior of the member 13. The rod 16 thus braces the supporting part 14 and, by means of the nut 17 the shelf may be adjusted sothat it is horizontal from front to rear.

In the part 13 above the opening through which the rod 16 passes is another opening throughwhich passes a bolt 18. This bolt has at the rear-end thereof a head 19 which is ofsuch size that it will pass through the relatively large upper end portion 20 of the keyhole slot in the member 10 but will not pass through the relatively narrow lower part of the slot. Also, as shown in Figure 3,

the bolt 18 has a part 21 adjacent to the head 19 which is of larger diameter than the shank of the bolt and smaller than the head. Also, this part 21 of the bolt is preferably tapered, increasing in diameter toward the head 19.

Referringto Figure 2, the lower relatively narrow portion 22 of the keyhole slot has its sides notched or cut away at 23 and 24 so that the relatively narrow portion is somewhat widened at this part. The part 23'-24 of the slot is of a size to receive the tapered portion 21 of the bolt, while the part 22 of-the slot is of smaller width, permitting easy passage of the shank of the bolt but not of sufficient width for passage of the part 21. The slot thus comprises three separate portions, the relatively wide portion 20 of a size to accommodate the head 19 of the bolt, the lower part 2324 to receive the part 21 of the bolt, and the intermediate still narrower part 22.

In mounting this shelf support in position,

the member 10 isfirst secured against the wall; the bolt 18 is inserted through the opening therefor in the part 13 and the nut 25 is threaded loosely upon the bolt. Thereupon', therbolt head 19 is inserted through the upper relatively wide portion 20 of one of the keyhole slots, the slot selected depending upon the height at which the shelf is desired to be supported. The head 19 having been inserted into the keyhole slot, and the nut 25 being loose, the member 1314 is allowed to slip downwardly, the shank of the bolt 18 moving through the part 22 of the slot until it reaches the lower portion 2324. Thenut 25 is now tightened up to draw the part 21 into the slot portion 2324, the parts being preferably so proportioned that the tapered part 21 wedges to someextent against the sides 23 and 24. The nut 25 having been tightened and the part '21 thereby drawn into the slot 1 7 portion 2324, the bracket member 1314 is effectively locked against upward movement until the nut 25 is again loosened to permit rearward movement of the bolt 18. The

narrowed portion 22 of the slot forms a posiber 10 are so spaced" that, when the bolt 18 is in the top slot, the end 16a of the bracing member 16 takes into the middle slot; when the bolt 18 is in the middle slot the end 16a takes into the bottom slot, as is illustrated in the drawings. About the opening in the part 13 through which the bolt 18 passes the metal is preferably forced outwardly as shown at 13a in Figure 3. As shown in Figure 4, the

opening 13?) through this part 13a is squared and, as shown in Figure 4, the shank of the. bolt 18 is correspondingly squared or flattened. The engagement of the squared shank of the bolt with the squared opening 13?) holds the bolt against rotation as the nut 25 is turned to loosen or tighten the support.

As has been mentioned earlier herein, the outer end of the arm 14-has an upwardly bent portion 14a which holds the shelf member 15 from sliding forwardly. Referring to F igure 3, positioned upon this portion 14a of the arm is a member 26 for the purpose of preventing the shelf 15 from being accidentally lifted upwardly. This member 26, which is shown in detail in Figures 5 and 6, is preferably stamped from sheet metal and comprises a fiat portion whichoverlaps the edge of the shelf member 15, and a downwardly extending part 26a which embraces the part 14a. In the part 14a is provided an opening 27. In the part 26a of the member 26 is stamped a small projection26b which snaps into the opening 27 when the part 26a is slid into place upon the part 14a, and which yieldingly holds the member 26 in'position. The member 26 may be removed easily by simply gripping the part 26a with the fingers and pulling upwardly and yet it dependably holds the shelf member 15 against being accidentally tipped up at the front. A pressure upwardly of the shelf member against the part 26 effects a lever action which causes the part 26a to bind and firmly hold on the part 14a. Thus, if the shelf 15 is accidentally struck from below, it cannot tip and articles carried thereon are not disturbed. When it is desired to remove the shelf member the members 26 are easily slipped out of position as described above.

The bracing rod 16 is secured at its forward end underneath the forward portion of the horizontal bracketarm 14, as shown in Figure 3, preferably by means of a suitable rivet 16?). From the rivet 16Zithe rod 16 slopes downwardly and rearwardly and is bent to extend horizontally at its threaded portion 1666 which, as above described, passes through an opening in the vertical bracket arm 13 and enters one of the keyhole openings in the supporting member 10. As shown in Figure 3, the rear end of the part 16a has formed therein, on the underside thereof, a notch 160. This notch is adapted to engage with the member 10 at the bottom of the slot, as shown in Figure 3, and it thus holds the bracing rod 16 from direct forward with drawal, it being necessary to raise the bracing rod at its rear end to disengage the notch before it may be removed. This notch 160 thus holds the bracket member 1314 against tippingupwardly atthe front. If the front portion of the bracing rod 16 or the front portion of the horizontal bracket arm 14 is accidentallystruck from below, the action of thenotch 160 prevents tipping.

In Figures 7 and 8 there is shown a modification of the construction just described.

the relatively large part 20 of the keyhole slot, but will not pass through the lower part thereof. hen the supporting bracket is placed in position against the member 10,-and when the bolt head 19 is inserted throughthe enlarged portions of its keyhole slot, the part 164 of the bracing rod is inserted through the upper enlarged portion of the keyhole slot positioned to receive it; then the bracket is moved downwardly" to bring the bolt head into position with respect to the narrow portion of its slot while, at the same time, the part 16d mov es downwardly into the narrow portion of its slot. The part 16d thus locks the lower portion of the supporting bracket against direct forward withdrawal and prevents tipping of the shelf in case the rod 16 or the horizontal arm 14 are struck accidentally from the bottom. When the construction shown in Figures 7 and 8 is employed, the opening in the vertical bracket arm 13 through which the part 16a passes is in the form of a vertical slot. In assembling the device, prior-to fastening the member 16 and the bracket member 1314 together, the nut 17 is threaded into place and the flattened end 16a is then formed on the rod. Thereupon, the flattened end 16d is inserted through the vertical slot in the part 13 and then the member 16 is swung through 90 to bring it into the position shown in Figures 7 and 8 there upon, the forward end of the member 16 is riveted to the part 14 by the rivet 16?), as shown'in Figure 3.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
