JOHN D. \VALSH, OF OOVINGTON, KENTUCKY.
EXTENSION BOOK-CASE.
SPECIFICATION forming part of Letters Patent No. 348,252, dated August 31, 1886.
Application filed January 11, 1886. Serial No. 188,270. (No model.)
To all whom it may concern.-
Be it known that I, JOHN D. \VALSH, of Covington, Kenton county, Kentucky, have invented a new and useful Improvement in .Folding Extension Book-Cases, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, in which- Figure 1 is a perspective View of my bookcase. Fig. 2 is a view in perspective of one corner of my book-ease.
Similar letters of reference in the several drawings denote the same parts.
My invention relates to a system of portable shelves, and more especially to such a system when it is used as a portable extension book-case.
The advantage of my system, in addition to being portable, is in the small amount of lumber required. for a book-case of a given capacity compared with an ordinary book-case,
- and also in the case and simplicity with which it is put together or enlarged.
My invention consists, reference being had to the accompanying drawings, of the side pieces, A and A, the top and bottom pieces, B B and O C, and of the means for rigidly connecting these pieces. The pieces 0 and O B B are spliced on their inner ends, having the tongues or projections/"f and f f. The outer ends of the pieces 0 G and B B are cut in dovetail tongues,whieh fit into corresponding dovetail grooves in the end of the end piece, A, as shown in Fig. 2, and the inner ends of A and A are cut so that they interlace or overlap. The pieces B B are made in every respect as G C. The center upright pieces, A and A, are in all respects similar to A and A.
m m are braces extending from the end pieces, A and A, to the top pieces, B and B, and to the bottom pieces, 0 and G.
o 0 are screw eyes let into the upright pieces and serve as a support for the shelves n a. By means of said screw-eyes the height of any one shelf and the distance between shelves may be readily adjusted. I obtain by this means a decided advantage over the ordinary book-shelf using notched pieces.
E is a metal plate on the outside pieces, A and A, to which the rod F is attached, said rod F being in two pieces, one on each side of the nut H, which nut H serves to lengthen and shorten the said rod F and so to bind the book-case together.
The overlapping ends of the pieces A A and A and A may be of any desired length, in order that the rod F may be higher or lower in said laps, as the relative distances between shelves may require.
It is evident that the combined effect of the rod F and the braces m serves to render the book-case extremely rigid, however light the pieces used to make it.
If it be desired to extend this bookcase, it may be done by inserting additional pieces composed in all respects as are the center pieces (shown as A and A") and additional top and bottom pieces meshing with thetongues ff and ff of pieces 0 and C. It will be seen that the pieces A and A fit into the top and bottom pieces with a dovetail, as at 1), Fig. 1. My book-case may also be made with the upright pieces unbroken.
Having thus described my invention, what I claim as new, is
1. In a portable book-case, the top pieces and the bottom pieces cut so as to inter-mesh, and held together by a central upright piece which fits into them horizontally with a dovetail, substantially as described.
2. In a book-case, the clamping-piece E, the rod F, the nut II, the end pieces of said bookcase, and the intermeshing top and bottom pieces of said book-case, substantially as de scribed.
The foregoing specification of my invention signed by me this 2d day of January, A. l). 1886.
JOHN D. VALSH.
