SPECIFICATION forming part of Letters Patent No. 541,395, dated. June 18, 1 895.-

Application filed April 16,1894- Serial No. 507,721- (No model.)

To all whom it may concern:

Be it known that I, GEORGE STIKEMAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Library-Shelving; and I do hereby declare the following to be a 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 has relation to library shelving and relates in particular to that class of shelving which is built-up in stacks, the framework consisting of an iron or steel structure and the shelves being either of wood or metal and supported at each end on metallic brackets adjustably secured to the upright beams of the framework.

My invention consists in the novel construction, arrangement, and combination of parts, more fully described hereinafter and specifically pointed out in the claims.

My invention consists in the provision of a novel shelf bracket comprising a vertical leaf, a vertical flange projecting laterally from said leaf and a clamping device adapted to support the bracket upon a vertical column, standard or beam.

Referring to the accompanyings drawings, Figure 1 is a plan View of shelving constructed according to my improvement; Fig. 2, a detail top view of one of the upright standards and two brackets. Fig. 3 is a front View of the shelving; Fig. 4, a perspective view of one of the brackets, and Fig. 5 a detail sectional view of one of the brackets andpart of a shelf.

A, designates the floor upon which the framework rests and B, B, B, the bases supporting the vertical columns of the structure.

In Figs. 1 and 3 of the drawings I have shown at each side of the view a column adapted for use at the end of a gallery or section of shelves and in the middle of each figure a column suitable for use at intermediate points. The end columns consist each of a flat vertical plate 0, and a channel iron D, while the central or intermediate column consists of a flat vertical plate 0 and two channel irons D, D. The vertical plates and the channel irons which compose each column are firmly braced and held at proper distance apart by means of bolts d, cl, and are of any required height, and the several columns of the structure may be connected by tie-rods at suitable points.

The brackets, which are secured to the vertical columns and support the shelves, each consist of a. vertical plate F, having at its inner edge a vertical flange G, that embraces the flange of the channel iron D, anda screw G, which passes through a nut H, formed on or attached to .the bracket and bears against the outer side of the channel iron and serves to secure the bracket in any position to which it may be adjusted. The screw G, is preferably of such length as to extend to the outer edge of the bracket, and is guided and sustained at or near its outer end by a lug I, through which it passes as shown.

The nut H and lug I, serve as hangers for the support of a narrow, horizontal shelf or flange K and where the bracket is made of cast metal, theflange K, lug I, and nut H, may be all cast integral with the bracket.

The shelves M, M, shown in the drawings are merely flat boards of proper length and their ends rest upon the flanges K of the brackets and are supported thereby, but the shelves may be metallic castings or of rolled or wrought metal if desired.

The brackets are placed in position by inserting the vertical flange of the bracket in the space between .the flange of the channel iron D and the plate G, and then turning the bracket to a right angle position relatively to the flange on channel iron D, when the screw G is tightened up, and will serve to hold the bracket firmly in place.

The manner in which the brackets are placed in position will be readily understood by reference to Fig. 2 of the drawings which shows the bracket on the right in proper position, and the bracket on the left about to be fixed in position by moving it in the direction of the arrow. To adjust the shelves in avertical direction it is not necessary to remove them from engagement with the columns, but it is only necessary to loosen the screw G sufflciently to permit the bracket to be moved up or down to the required position and then tighten up the screw. As'the bracket will hold at any position on the column, any required adjustment, however: slight, may be easily attained.

Having described my invention, I claim-- 1. A bracket for library shelves, consisting of a vertical plate having a vertical flange at its rear edge, a horizontal flange-on .its inner side and below the upper edge of the plate, a threaded nut or lug and a perforated guiding lug on the inner side of the plate, in combination with a screw passing through the lug and nut and extending to the front edge of the plate, substantially as described.

2. In library shelving, the combination ofia column composed of a flat plate and a channel iron mounted on a suitable .base and secured at such distance apart asto leave a space between the flange of the channel iron channel ironvsecured to the base and arranged at such distance apart as to leave a space between the flat plate and the flange of the channel iron for the reception of a bracket, substantially as described.

In testimony whereof I have affixed my sigo nature in presence of two witnesses.
