To all whom t may concern:
Be it known that I, JAMES H. Born, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Shelf Supports, of which the following is a specication.
This invention relates to improvements in shelf supports, and has been designed more 1U particularly, although not exclusively, for use in connection with glass shelves, such as are now extensively used as bathroom fixtures to carry toilet articles.
Heavy glass plate shelves of this character, being expensive and easily breakable, require to be not only strongly supported, but also securely anchored or otherwise held to their supporting means against accidental displacement. Furthermore, it is desirable for at least two reasons to avoid the use of fastening means passing through the glass shelf itself. In the first place, the top surface of the shelf should be left smooth and free from any upstanding projections interfering with or lessening the surface required for toilet articles thereon, and in ythe second place, the aperturing of heavy glass plates to provide fastening means is a difficult and expensive operation.
One object of my present' invention is to rovide a simple, strong and secure means for both supporting and securely holding in place a glass or other shelf which will leave the top surface thereof unobstructed for the deposit thereon of toilet or other articles. Another object of the invention is to pro- Vide a shelf-supporting means which will be readily adjustable to fit shelves of considerably varying lengths and widths. A further object is to provide a shelf support, including a pair of brackets adapted for attachment to the wall, wherein shelves of considerably varying lengths and widths can be not only supported but securelyV clamped and held in place without involving readjustment of the relative positions of said brackets on the wall.
Other objects and attendant advantages of the invention will be readily' apparent to persons skilled in the art as the same becomes better'understood by reference to the following detailed description, taken in connection with the accompanying drawing wherein I have illustrated one practical and approved embodiment of the invention, and in which- A y Fig. 1 is a front elevation of a glass shelf embodying my improved supporting and holding means; a
Fig. 2 is an enlarged end elevation, viewed from the right of Fig. y1; f
Fig. 3 is an enlarged top plan View of the right hand bracket lshown in Fig. 1, withy an overlying portion of the glass shelf indicated by dotted lines; a
Fig. 4 is an enlarged sectional detail taken on the line 4-4 of Fig. 3; and
Fig. 5 is an enlarged vertical sectionV through the rear end of the bracket plate and its supporting arm.
Referring tothe. drawing, 10 designates .a rectangular shelf, which preferably' consists of a vheavy plate of glass such as is extensively used in the manufacture of bathroom shelves for holdingy toilet articles. This shelf is supported and securely held by a pair (right and left) of brackets, which are structural duplicates, and eachof which, in the embodiment shown, is constructed as follows. 11 designates a hollow sheet metal elbow bracket arm, the forward upwardly turned end of which is divided and branched outwardly as shown aty 11 in Fig. 3 and secured by rivets 12 to the under side of a fiat horizontal plate 13 on which the shelf 10 directly rests. At its inner end the bracket arm 11 is formed with a wide vertical base flange 14: that is apertured on opposite sides for the passage of fastening screws 15. The flange 14, is also provided at its upper end with an aperture 16l for -a purpose rherein- Y plate 13 with its slot 21 in register with the hole occupied by the screw 18. This latter extends through the slot 21 and is` equipped with a washer 22 and a binding nut 23; the screw, washer and nut thus constituting a clamp by which' the arm 19 is rigidly attached to the under side of the plate 13 .with capacity for endwise adjustment and also an ular adjustment in a horizontal plane.
n its forward end the arm 19 is formed with a pair of upstanding hooks 24 and '25 disposed at right angles to each other, the hook 24 engaging with a front edge of the shelf 10, and the hook 25 engaging with a side edge of the shelf adjacent to the corner formed by ysaid edges. These hooks 24 and 25 constitute-stopsftofprevent displacement of the shelf forwardly or sidewise in its own plane,and Vthey alsofserve further toj'grip the front .corners of the shelf against accidental displacement upwardly.
The rear edge of the shelf is held down by a wide upstanding hook .26 formed on and integral with the rear ledge of the plate 13, ras'clearly shown in Figs. 2and 5. 'Y The plate 13 is preferably, andfor greater rigidity, secured at its rear end to therbase Aflange l14 lof the elbow bracket arm 11' by means of an inte-gral hook-27 (Fig. 5) struck .downwardly lfrom the plate 13 and its hook QB'and-p'assed through the aperture 16 of the base iiange 14;.
From the, foregoing description of the lstructural features of the invention it will Teadily beperceivfed how the stated purposes and objects are atta-ined thereby. The structnre'require's no perforation or other cutting of the shelfv itself, and leaves the top surface thereof entirely clear and unobstructed, save :for the small hooks 24, 25 and 26 attheextreme edges thereof. In mounting the shelf, v
`no Aexact, relative positioning of the two brackets in yorder to fit the shelf is required. The two brackets are secured to the wall at approximately the proper positions determined by lthelength of the shelf, and thelat- I"ter is 'then laid lthereon with its rear edge *underlying the hooks 26. The thumb nuts Vlr23 Iare then loosened, and the arms 19 are :adjusted to a position wherein their hooks y24"'and 25snugly grip'the front corner ofthe s-helf. yThe thumb `nuts 23 are then tight` ened, and the shelfis securely and strongly supported and held in place against Vdisplacement in any direction.
If it is'desired to'replace the'shelf by an- -other of different length or width, or both, -within the longitudinal limits of the slots 21 of thearms 19, this can readily be done, the'armsbeing fitted to the corners of the shelf inthe manner `already described, -t will .be -observed'that in thedescribed conv`struction `a single pair of adjustable varms 19, through engagement with both the front l-and'sidef'edges of the shelf, accommodates ivboth endwise and widthwise variations; but fobviously `separate, arms, one to take care of widthwise variations and theother to take care of endwise variations, might be employed on each bracket, if desired, within the plan and purview of the invention. It is also manifest that the described structure maybe otherwise varied in details without involving any departure from the substance of the invention or sacrificing any of the advantages thereof. Hence, I do not limit the invention to the particular structure shown and described, eXcept to the extent clearly indicated in specific claims.
I claim- 1. A shelf-supporting bracket comprising, in combination, a flat horizontal plate von which the shelf rests, supporting means for said plate adapted for attachment Vto-a wall, and an arm attached to said plate with capacity forboth endwise adjustment and an'- gular adjustment in a horizontal plane, said arm having at its forward end a pair of upstanding hooks adapted to engage respectively with the front and a side edge of the shelf adjacent to a corner of the latter.
2. A shelf-supporting bracket, comprising, in combination, a' Hat horizontal plate on which the shelf rests, said plate formed at its rear edge .with an integral upstanding hook adapted to engage with the rear edge of the shelf, supporting means for said .plate adapted for attachment to a wall, and an arm attached to said plate with capacity -for both endwise adjustment and angular adjustment in a horizontal plane, said arm having at its forward end a pair of upstanding hooks adapted to engage respectively with the front and a side edge of the shelfadjacent to a corner of the latter.
