STACK CONSTRUCTION.
SPECIFICATION forming part of Letters Patent No. 775,497, dated November 22, 1904.
Application filed March 21, 1904.
To to whom it may concern Be it known that I, NEWELL B. PARSONS, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stack Construction, of which the following is a specification.
My invention relates to certain new and useful improvements in stack construction; and its object is to produce a device of this class which shall have certain advantages which will appear more fully and at large in the course of this specification.
To this end my invention consists in certain novel features of construction, which are clearly illustrated in the accompanying drawings and described in this specification.
In the aforesaid. drawings, Figure 1 is a front elevation of a library-stack embodying my invention. Fig. 2 is an end View thereof. Fig. 3 is a section in the line 3 3 of Fig. 1 looking in the direction of the arrow. Fig. 4 is a section in the line 4 4 of Fig. 3 looking in the direction of the arrow, and Fig. 5
is a section in the line 5 5 of Fig. 3 looking in the direction of the arrow.
- Referring to the drawings, which Show the preferred combination, A A are suitable vertical supporting-posts at the two ends of the stack, these posts bearing shelves B. The construction of the posts and shelves is not at all material to my invention. happens to be here illustrated is that fully described and explained in the joint application of myself, William H. Winslow, and Jackson L. Kail, filed on even date herewith and allotted Serial No. 199,272. At the top of each support A is secured a bracket O. Each bracket C, it will be noted, spreads out from i the top of the post toward the front and rear of the stack, the particular form illustrated being designed to give a satisfactory appearance to the device rather than for any mechanical effect. The brackets are secured to the top of the posts A, and their upper ends extend substantially across the width of the stack, the inside of each bracket having a channel C, which is rounded at the ends, the rib or flange ipg indicated which incloses this channel bein the drawings by c. A shelf The form which 1 Serial No. 199,262. (No model.)
D is supported by the brackets C. This shelf is preferably made of a single piece of sheet metal, the longitudinal edges of which are bent around to form cylindrical beads (Z, which give rigidity to the shelf and also give it a finished appearance. The edges upon the ends of the shelf are bent down to form flanges d, which rest upon the, lower ribs or flanges c of the brackets C.
Through each of the beads d extends a rod E, the ends of ,which pass through suitable perforations c in the brackets O. The rods E are screw-threaded at the ends and are held in place by ornamental nuts E.
It will be seen that by this construction a shelf isprovided of substantially the width of the stack. which not only gives extra shelf room for any purpose, but which protects the books in the stack from dirt which might otherwise fall upon them. The fact that the rods E connect the ends of the brackets braces the stack very firmly and prevents any twisting of the vertical supporting-posts.
I realize that considerable variation is possible in the details of this construction without departingfrom the spirit of the invention, and I therefore do not intend to limit myself to the specific form herein shown and described.
I claim as new and desire to secure by Letters Patent 1. In a device of the class described, the combination with suitable vertical supportingposts, brackets secured to the tops of the posts and extending therefrom substantially to the front and rear ofthe structure, channels on the inner faces of said brackets, and a suitable shelf supported by said channels.
2. In a device of the class described, the combination with suitable vertical supportingposts, brackets secured to the tops of the posts and extending therefrom substantially to the front and rear of the structure, channels on the inner faces of said brackets, and a sheetmetal shelf having cylindrical beads along its edges supported by said channels.
3. In a device of the class described, the combination with suitable vertical supportingposts, of suitable brackets secured to the upper ends thereof and extending substantially to the front and rear of the structure, channels having rounded ends on the inner faces of said brackets, and a sheet-metal shelf having cylindrical beads along its edges supported by said channels.
4:. In a device of the class described, the
combination With suitable supporting-posts, of suitable brackets secured to the tops of the posts, a sheet-metal shelf having cylindrical beads along its longitudinal edges, and suitable rods extending through the ends of the brackets and the cylindrical beads.
5. In a device of the class described, the combination With suitable supporting-posts, of brackets secured to the upper ends thereof and extending to the front and rear of the 25th day of February, A. D. 1904:.
- NEWELL B. PARSONS.
