MIOHEAL J. BRESLIN, OF ALBANY, NEW YORK.

METALLIC SHELVING.

. SPECIFICATION forming part of Letters Patent No. 510,562, dated December 12, 1893.

Application filed June 2, 1893. Serial No. 476,414. (N 0 model.)

.To aZZ whom it may concern:

Be it known that I, MIOHEAL J. BRESLIN, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Metallic Shelving, of which the following is a specification.

My invention relates to improvements in the construction of metallic shelving for libraries, and other purposes, wherein it is desirable to have the shelves adjustable in re spect to their vertical spacing from each other so as to adapt them to receive books or other articles of difierent heights, said shelving being made entirely of metal so as to be practically fire-proof; sa'idshelving consists of tubular uprights which are preferably connected together in pairs and are provided on diametrically opposite faces with aseries of openings to receive supports for the shelves, said supports being fitted to engage in either of said openings as occasion may require.

In the accompanying drawings, which are herein referred to and form part of this specification, Figure 1 is a transverse vertical section of a stack of my shelving at the line X X on Fig. 2. Fig. 2 is a front elevation of two stacks of my shelving. Fig. 3 is an enlarged transverse section of the upper part of a stack of my shelving. Fig. 4 is a longitudinal section of the same at the lineY Y. Fig. 5 is a perspective view of a removable crossbar for adjusting the height of the shelves, one end of a shelf being indicated by dotted lines. Fig. 6 is an end elevation of thelower portion of a double stack of my shelving; and Fig. 7 is a detached front elevation of the middle upright for the latter.

As shown in the drawings, A designates a stack of my improved shelves, consisting of pairs of tubular uprights, B, which are connected together by means of cross-ties, C, so that a pair of said uprights will form an end for a stack of shelving; each of said uprights is providedon diametrically opposite faces which are at right angles to the line of the stack-with a series of spaced openings, D, preferably arranged atequidistant intervals, for the purpose of varying the vertical distance between the shelves. E designates a removable crossbar for supporting the shelves said cross-bar is bent, as at 1, at each end of it to form an arm, 2, to enter either of the openings D, and each arm is provided with a hook, 3, at its inner end for the purpose of engaging in the tubular uprights for securing the crossbar in place,

F designates a metallic shelf adapted for use with the cross-bars E; said shelf is provided with a narrowed portion, 4, at its opposite ends, that will enterbetween the uprights B and prevent the shelf from being accidentally displaced from its position. The edges of said shelf are bent to form a rounded edge, as at 5, as indicated by the dotted lines on Fig. 5, said rounded edges givingstrength to the shelf, and affording facilities for turning large volumes over the edge of a shelf without inflicting damage to the covers of the book.

Preferably each uprightB is provided with a base, 9, and cap piece, 10, and when so constructed several tiers of said shelving can be arranged one above anotheras may be required, beams, 11, being provided for holding a foot-way between each tier to afford means for attaining access to the upper tiers. The end sections being erected at the required places, and the shelves fixed thereon-in the manner hereinbefore describedthe stacks of shelving are in condition for receiving the books or other articles.

Two stacks of shelving can be placed backto-back as shown in Fig. 6, so as to arrange the shelving clear from the walls of a room, and thereby the room can be more fully utilized than when theshelving is placed against the walls. When constructed in this manner, the ends of the stacks are formed of three uprights, B, the middle one of which preferably has the openings D formed with a straight horizontal line, as illustrated in Fig. 7, so that two of the cross-bars E can be entered into said opening and extend in opposite directions as indicated by dotted lines in said figure.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with tubular uprights, B, connected together by cross-ties, O, and provided with correspondingly spaced openings, D, of a removable cross-bar, E, having at each end a lateral arm, 2, fitted to enter 10 each end a lateral arm, 2, fitted to enter the openings D 5 each of said arms being provided with a hook, 3, adapted to engage in the bore of said tubular uprights, of a removable metallic shelf, F, having its longitudinal edges strengthened by rounded bends, as and for 15 the purpose specified.
