BOOK-SUPPORT.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed December 1,1904 Serial No. 235,012.

- taining a full, clear, and exact description,

reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in book-supports; and the object of my invention is to provide bookcases and shelves with a simple inexpensive attachment which is adapted to maintain the books arranged in the cases or upon the shelves in upright positions.

A further object of my invention is to so construct a book-support as that it will readily swing both inwardly and outwardly and which support will be provided with abroad bearing at its pivoted end, so as to prevent a tendency to lateral play or movement While in operative position.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of abookcase,

showing my improved book-supports in position thereon. Fig. 2 is a vertical section taken through the center of a bookcase equipped with my improved support. Fig. 3 is a perspective view showing a pair of thesupporting; members arranged upon the supportingro Referring by numerals to the accompanying drawings, a pair of attaching-plates 8 are rigidly secured in any suitable manner to the inner faces of the end walls 9 of a bookcase immediately beneath the top or a shelf therein, and said plates 8 are provided with centrally-arranged bearings 10, in which the ends of a wire rod 11 or shaft are located.

Sleeves 12 in the form of short tubes are arranged for rotation upon the rods or shafts 11, the ends of which sleeves bear against one another and said sleeves-extending in a series from one end of each rod to the other.

Supporting-fingers 13 in the form of stiff wire rods are rigidly secured in any suitable manner to the sleeves 12, and as said sleeves are free to rotate on the rods or shafts 11 these supporting-fingers will by their own weight normally maintain vertical positions.

When a book is located in the bookcase equipped with my improved device, it is merely moved inwardly-upon the shelf or bottom of the case, and in so doing it will swing one or more of the supporting-fingers upwardly and re'arwardly, and the adjacent supporting-fingers will maintain their vertical positions at the sides of the book, and thus prevent it from falling in either direction.

The sleeves 12 being loose upon the shafts 11 readily yield to the movements of the inserted books, and as soon as a book is removed the fingers will at once resume their normal vertical positions.

The sleeves 12 being of some length provide wide bearings for the supporting-fingers, thus reducing any tendency of said fingers to swing sidewise. a

I claim The combination with a bookcase, of attaching-plates secured to the inner faces of the end walls of said case immediately beneath the front of the book-shelf, a rod having its ends mounted in the attaching-plates, a series of tubular sleeves rotatably arranged on the rod, the series of sleeves extending from one end of the rod to the other, and a supportingfinger rigidly fixed to and depending from each sleeve; substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

JAMES MACCALLUM.
