To @ZZ whom, it may concern:

Be it known that LWILLIAM VAN HORN, a citizen ofthe United States, residing at Piqua, in the countyof Mianiiand State of Ohio, have invented certain new and useful Improvements in Adjustable Brackets; and Ido hereby declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to adjustable brackets for shelving.

The object of the invention is to furnish a more convenient device than has heretofore been used, and one by which shelves can be adjusted to any height or taken down and put up at pleasure.

The invention, broadly stated, comprises a vertical strip adapted to be attached to the wall, and herein called a wall-strip, having an angular or T-shaped front portion having on its inner face one or more rows of teeth or notches, and abracket having a vertical standard adapted to engage the vertical Ways of said wall-strip, and having one or more lugs thereon to engage with the teeth thereon.V

In the accompanying drawings, Figurel represents a perspective view of the standard or wall-strip having a single row of teeth or notches with a bracket in position thereon,the dot-ted lines representinga shelf in position on the bracket. Fig. 2represents an inner perspective view of a bracket. Fig. 3 represents a detail sectional view of the bracket-clutch, the dotted lines in this figure representing the wall-strip engaging therewith. Fig. 4 represents a perspective View of a double wall-strip for sectional shelving with a pair of brackets in position thereon. Fig. 5 represents a perspective view of a modiiied forni of bracket. Fig. 6 represents in front elevation a series of sectional shelving constructed and arranged according to my invention.

1 represents the vertical wall-piece or standard,which is composed of three essential elements--viz., the back plate, 2, which can be secured to the wall by means of bolts o'r screws passed through the holes 3 therein,the outwardly and forwardly extending rightangled or T-shaped portion 4, having rib or plate 5,and the rib or fia-nge 6, having notched or toothed inner face, 7. This wall-piece or standard l is constructed of any suitable material-as, for instance, in a single piece of malleable or cast 1netal-and may be con- 55 strncted in any length desired, one face of each end being formed with a recessed or cutaway portion,8, to facilitate the splicing thereto at either or both ends ofadditioual lengths or sections of a wall-piece. The notched in- 6o ner face, 7, of the rib 6 is formed with a series of bevels, 9, one between each two notches 7, running from the inner edge ot' one notch to the outer edge of the next.

10 represents a notch or recess formed in the 65 rib 5 to admit the clutch on the braclret,to he presently described.

In Fig. lthe wall-strip is represented as provided with but a single row of teeth 7, and in this forni is adapted for use in those cases 7o where the shelves to be supported on the brackets are of a single length and extend continuously from the wall-piece or standard l at one end of the set of shelving to the wall-piece or standard at the other end thereof. When, however, it is desired to construct the shelvingin sections horizontally, I construct the center wall-piece or standard l of double ferm, as represented in Figs. and 6 of the drawings, and with a double row of teeth 7 to re- 8o ceive the lugs on the bracket-standards, to be presently described. The adaptation of my appliances for use in connection with sectional shelving will be fully described herev inafter. 85

12 represents the bracket, which is formed, preferably, in a single piece of suitable material-as, for instance, of cast or malleable metal-*though it may,'if desired, be formed in sections and connected togetherin any known go way. The bracket comprises an upright or standard, 13, which, when the bracket is in position, rests within the wall-piece, the lower portion of the inner edge of thisstandard being straight, as shown at 1d, to rest against 95 the back plate, 2, and extending upward in a straight line to the point 15, which bears against the back plate, 2, and acts as a fulcruni, as presently described, and from thence the inner or rear edge of this standard extends in roo the form of a bevel, 16, to the top, a lug, 17,

of a shape to adapt it to engage the notches or teeth 7, being formed on one face of the standard or upright 13. Midway or at any other suitable portion of this standard 13 is a right-angled clutch, 18, having a hook-shaped outer end, 19, which embraces and grips the iiange or rib 5, as clearly represented in Fig. 3, ahorizontal arm, 20, upon which the shelf rests, and asupporting and strengthening rib, 21, at the bottom of the standard 13.

The wall-strips or standards 1, having first been constructed to the desired height, or the requisite number of sections thereof spliced together at 8, they are then secured in position on a wall by passing screws, bolts,or other retaining` devices through the holes 3. The brackets 12 are then secured in position upon said standards in the following manner: For the sake of convenience of description I will state the operation followed in placing a single bracketin position, it being readily understood that the saine method is followed in placing each of the brackets in position. The inner edge ofthe bracket is placed in position within the wall-strip, as represented in Fig. 1, with the beveled portion 16 thereof' resting against the back plate, 2, and the lug 17 between the back plate, 2, and the ribbed or T-shaped portion 4. The bracket isthen moved up ordown along the standard 1 until the clutch 18 comes opposite the notch or recess 10 in the rib 5. The clutch is then slipped into said notch or recess 10 and the hook-shaped outer end, 19, of the clutch slides along under the rib 5. Then, by pressing down on the arm 20, the point 15 on the rear or inner edge ofthe standard 13 forms afulcruin and throws the upper end of the bracketstandard 13 forward and brings the lug 17 into operative engagement with the notches 7. The straight portion of the standard 14 15 will then rest against the face or back plate, 2, of the wall-strip, and this lug 17 and the notches 7 operate together to hold up the weight of the bracket 12. In order to raise the bracket, the hand is placed under the arm 20 and an upward pressure exerted thereon, whereupon the bevels 9 between the notches 7 will force the lug 17 out of the notch with which it is in engagement, and thereby disengage it from contact with the notches. Vhen the bracket is high enough,

the hand is removed from under the arm 20,-

whereupon the weight of said arm will be thrown upon the point 15,which act will cause the upper end of the arm or upright 13 to drop forward and bring the lug 17 into operative contact again with the notches 7. In order to lower the bracket, I take hold of the horizontal arm 20 and pull it away from the standard 1,whereupon the hooked end 19 of the clutch 18 will be-brought to bear against the inner face of the rib 5 and act as a fulcrum and cause the upper end of arm or bracket-stand ard 13 to drop back, so that the beveled portion 16 of said arm 18 will rest against the front face of the plate 2 and the lug 17 thereon will be disconnected from the notches 7. The bracket is then allowed to slide downward in this position` as far as desired. Upon reaching the desired position, I then let go of the arm 20, whereupon the weight of said arm, in connection with the fulcrum 15,will bring the top of arm 13 forward again and again lock the lug 17 into the notches 7. A series of brackets may be placed upon one standard one above the other, and a series of standards may be placed against a wall, thus forming a cheap and convenient support for shelving, which can be raised or lowered or taken down at pleasure.

The clutch 1S, besides operating as a fulcrum on the inner face of rib 5 for the throwing of the lug 17 out of contact with the notches 7, also acts, in combination with the rib 5, in holding the bracket 12 in its relative position to the standard 1, and it prevents a swinging motion on the lug 17, which would otherwise take place when pulling the arm 2O away from the standard if the clutch was absent.

In Figs. 4 and 6 I have represented a form of double wall-piece or standard adapted for attachment to the wall midway of the end wallpieces or standards of the character heretofore described. These double wall-pieces or standards are designed for use in such cases where it is desired to form the shelving insections horizontallythat is, with two separate rows of shelving side by side. The wall-pieces or standards in the form shown in Figs.4 and 6 are of substantially the same construction as heretofore described, except that they'are provided with two rows of notches or teeth 7. The brackets to engage the double wall-strip are, as represented in Figs.4 and 6,of the same construction as heretofore mentioned, except that where clutches 18 are employed the brackets should be made right and left-that is, with the clutch 18 and the lug 17 so positioned that one bracket can be secured to the right and the other to the left side of the standard 1.

In the form of wallpiece or standard represented in Fig. 4 the recess or notch 10 may be omitted, if desired, though its presence will not impede the operation. The bracket-standards, in lieu of having the clutches 18 thereon, may each be provided with a pair of lugs, 17, as shown in Fig. 5, which will in such case engage, respectively, with the double row of notches or teeth in the double wall-strip shown in Fig. 4.

When it is desired to construct the shelving in sectional form,wallpieces of the form illustrated in Fig. 1, at the right and left hand respectively ot' Fig. 6, are secured in position at the ends of the shelving and one or more of the double standards represented in Fig. 4 are se cured in position a suitable distance between the end standards, as shown in the center of Fig. 6. The brackets are then placed in p0- sition, as represented in the several figures, so that the ends of the several. shelves of each section will rest the one upon the brackets on the end standards and the other upon one of IIO the brackets in the double standard, as clearly represented in Fig. 6. By this arrangement any shelf or" either section can be vertically adjusted in position independently of either of the other shelves.

Having thus described my invention, what I claim is l. An adjustable bracket for shelving, comprising a wall-strip or standard consisting of a back plate adapted to be attached to a wall and having a vertical flange extending out- Wardly and forwardly therefrom, and an inwardly-extending rib or flange having a notched rear face, and a shelfsupport comprising a horizontal arm on which the sheltI rests, and an upright or standard on the inner end thereof having on its side faeealug to engage the notches on the wall-strip, and two fulcrums, one on the rear or inner edge of said standard and the other in about the same horizontal plane as but forwardly and sidewise of the first fulcrum, as and for the purpose set forth.

2. An adjustable bracket for shelving7 comprising a wall-strip or standard consisting of a back plate adapted to be attached to a wall7 a Tshaped vertical flange extending forwardly thereof and having a series of notches on the inner or rear face of the inwardlyextending portion of the T-Shaped portion7 and a shelf-support comprising a horizontal arm to receive the shelf, an upright or standard at the inner endthereof having a lug on its side face to engage the notches on the wall-strip7 and a sidewise-extending hook-shaped clutch to grip the outer member of the T-shaped flange.

3. An adjustable shelfsupport comprising notches and a straight lower and beveled or angular upper rear edge, and a hook-shaped clutch extending at an angle from the front edge of said upright, and a shelf-support extending horizoutally outward from said upright.

4. An adjustable shelf-support comprising a wall-strip having an outwardly and forwardly extending flanged portion and one or more centrally-extending ribs having a notched rear face7 and a bracket comprising an upright having a beveled rear edge and a lug or lugs extending sidewise from the side faces of and out of alignment with the rear edge of said upright7 and a forwardly-extending shclfsupport, substantially as and for the purpose set forth.

In testimony whereof Iatix my signature in presence of two witnesses.
