jBOOK-SUPPORT Be it knownthatL JAMEs 'MAcoALLUM, a

" "St. Louis, Missouri, have invented certain new and useful Improvements in Book-Supports, of whichithefollowing is a specification- I containing a full, ,clea'r, and exact descrip support; and'the obj ect of my invention is to provide book cases and .shelves with a simple tion, reference being I ad to'the accompanyinggilrawings, forming a parthe'reof.

y inventionrelates to an improved bookinexpensive attachment whichis adapted to maintain the books'arr'anged in-the cases or upon t'he shelves in upright positions. u To'the above purposes my invention con- 'sists in certain novel features. of construction and a1 rangement of.parts,'which will be hereinafter morefully set forth, pointed out in my claims, and illustrated in. the accompa' 1 nyin'g drawings; inwhichf Figure 1- is a front elevationiofa portion of a bookcase, or two compartments thereof, provided with improved book-support. Fig.

2 isa' vertical sectiontaken on the 1ine'2 2 of Fig. 1. Fig.1 3 isa perspective view of the bottom-off a bookcase andlshowing my improved attachmentin position thereon. Fig.

4 is an enlarged detail viewshowing the way the supportin -fingers are mounted on their 1 supporting-r0 1 'Referring'by numerals to theaccompanyv ing drawings 1 1 indicate the shelves or .bot'-,

toms of the bookcases, in the top surfaces of whichynear the" front edges, are formed the lqngitudinallyeextending grooves 2. Communicating with each" groove2 andv extendingrearwardly' in each shelf or bottom 1 is a series "of grooves 3..

- the groove 2, and the ends'of said rod are suitably-held at the ends of the bookcase or f shelf. Mounted for rotation onthis rod is a 6 series of short tubes 5, which completely fill 45 the grooves 2,,and fixed to the center of each tubeis a book-supporting finger 6 in the form of'a short'wire rod. Fixed to the rod 4 at one end of each of the tubes 5is one end of a coil-spring 7 that is loosely wound upon the v' zspe'cificat ion of iletters Patent.

' .4 indicates a wire rod that is positioned in Patented Oct. 23,1906.

rod 4, its opposite end being fixed to the tube 5. Thenormal tendency of these springs 'Z is to maintain the retaining-fingers 6 in vertical positions. vThetubes 5 are soarranged on the rods 4 as that when the fingers 6 swing rearwardly and downwardly they will enter the grooves 3, that are formed in the bottoms of the book cases or shelves.

When a bookis placed upon ashelf equipped with my improved supports, one or more of said supports will be forced rearwardly and downwardly as the bookis placed inpo sition, and the next adjacent supporting-finger will engage the sides of the book tOmaintain it in a vertical position. As soon as the book is removed from the case or shelf the springs 7 will act to return the supporting fin em 6 to their normal vertical positions.

bookcase of -my' improved construction is simple, inexpensive, easily applied to the .shelves of. bookcases, and very efficiently maintains thebooks placed on said shelves in I correct upright positions. cl aim 1. The combinationwith a bookcase; of a rod horizontally positioned across the front edge of-each shelf of the case, tubes arranged for rotation on said rod coil-springs secured at one end'to each tube and at the opposite end to the rod, and book-engagin fingers rigidly fixed to eachtube; substantia ly as specified.

I 2. The combination with a bookcase-shelf,

' having a groove formed in its top surface adjacent its front edge and there being grooves formed in said shelf that extend rearwardly. from the first-mentioned groove, of a rod arranged in the first-mentioned groove,v tubes arranged for rotation on said'rod, a book-engaging finger carried by each tube and coil springs secured to each tube for normally maintaining the book-enga ing fingers in vertical positions; substantially as specified. Iii-"testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
