BUILDINGCONSTRUCTION.

' SPECIFICATION forming part of Letters Patent No. 609,487, dated August 23, 189,8.

Application filed November 26, 1897; Serial No. 6 59,764. (No model.)

To @ZZ whom t may concern:

Be it known that we, WILLIAM H. WINS- Low and FRANCIS A. WINsL'ovv, citizens of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Building Constructions, of which the following isa specification.

Our invention relates to certain new and useful improvements in building constructions, and more especially to that class of building construction adapted for use in libraries and the like,where neatness, strength, and durability are required.

To such end it consists in a light, simple, and substantial framework containing certain novel features of construction, a description of which will be found in the following specification, and the essential features thereof definitely pointed out in the claims appended hereto.

The invention is clearly illustrated in the drawings furnished herewith by means of five figures, of which- Figure l is a side elevation of my construction. Fig. 2 is an end elevation, partly broken away. Fig. 3 is a vertical cross-section in line 3 3 of Fig. l. Fig. liis a central vertical longitudinal section through the device, certain portions being broken away to enable the View to be made as large as possible upon the sheet; and Fig. 5 is a horizontal section in line 5 5 of Fig. 4. Figs. 2 to 5, inclusive, are upon a larger scale than Fig. l in order to more clearly illustrate the invention.

In the views, A A A2 A A represent uprights or supporting members resting upon a suitable foundation and preferably bolted thereto.

B B B2 are horizontal members adapted Vto hold the uprights together and at proper distances from each other. The frame thus formed is braced by a truss C, extending diagonally from the middle of the frame to the angles made by the uprights A A and horizontalmembers B B2. This truss is adjustable for the purpose of truing up the frame and bracing it against longitudinal strain.

The different members of 'the frame are shown as of peculiar construction, andIwill now proceed to describe each separately. The uprights are each composed of a bar or -ing tubes or rods.

supporting-web a, (see Figs. 4. and 5,) slit at the bottom and the two ends bent at right angles to the main portions in opposite directions to form feet d', ada ted to be screwed or bolted to the floor. pon both faces of the uprights A A2 and upon the inner faces of the uprights A are provided clamp-bars 0,2, preferably narrower than the web 1-, spaced apart therefrom slightly and secured thereto in any suitable manner. These bars are adapted to support shelf-brackets (seen in Fig. 3) provided with suitable clamping means for adjustably securing them to the clam p-bars. The clamp-bars not only form a supporting means for the brackets, but also stiften the uprights, thereby increasing the rigidity of structure.

The horizontal members consist of tubes b, extending between the webs ct, tie-rods b', passing through the tubes and webs, and nuts b2 upon the ends of the tie-rods. By tightening up these nuts a rigid frame is formed; but in order to give it still greater rigidity I provide the frame with a truss C,

which consists of four diagonally-extend- Upon the ends of these tubes are secured crotches c c', adapted to engage the framework at the intersections made by the members A A', B B2, and A:2 A'. The crotches c are, however, provided with screws c2,the ends of which rest against the web of the upright A2, and by adjusting these screws the various parts of the truss may be moved longitudinally along the horizontal member B until the .frame is adjusted in perfect alinement and rigidly braced.`

It should be noticed that the different parts of this construction are simple and cheap,thus

lessening the cost and at the same time sim* plifying the structure. i

We claim as new and desire to secure by Letters Patent-- 1. In a building construction for libraryshelving or the like, the combination with uprights each comprising a main supportingweb and clamp-bars secured thereto, of horizontal connecting members comprising tubes extending from upright to upright, tie-rods passing through the same and connecting them together and braces extending between diagonally-opposite angles of the structure and provided with adj listing-screws adapted to vary the length of the diagonals and thereby true up and brace the structure; substantially as described.

2. A building construction for library-shelving or the like comprising webs, a, clampbars, a2, secured thereto, tubes extending between the Webs, tie-rods passing through the tubes and Webs and connecting the parts together, diagonal braces extending diagonally from approximately the middle of the center web, crotches in the ends of said diagonal braces engaging the tubes and webs and setscrews in the inner crotches bearing against the central web; substantially as described.

3. A building construction comprising uprights, A, A', A, horizontal connecting-bars,
