UNITED STATES JOHN E. WAMBLE, OF HINSONTON, GEORGIA.

REVOLVING LIBRARY AND DESK.

Specification of Letters Patent.

Application filed November 10, 1905. Serial No. 286.75 9.

To all whom it may concern:

' Be it known that I, JOHN E. WAMBLE, a citizen of the United States, residing at Hinsonton, in the county of Mitchell and State of Georgia, have invented certain new and useful Improvements in Revolving Libraries and Desks, of which the following is a specificatlon.

This invention provides convenient and compact supporting means for books, whereby any book or like article of a collection may be obtained without necessitating the person arising from a sitting position for the purpose.

The invention also combines with the revolving bookrack, a desk, upon which the selected book may be placed for reference and which also forms a support for the said rack, said desk also performing the usual office of an article of this type.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features .thereof, still the preferred embodiment is shown in the accompanying drawings, in which- Figure 1 is a perspective view of a revolving library and desk embodying the invention. Fig. 2 is a vertical central section thereof. Fig. 3 is a perspective view of the revolving library or book-rack. Fig. 4 is a horizontal section of the revolving library or book-rack.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

or it may be used in the accustomed manner for writing or in the capacity of a secretary- The leg-sections 4 are loc-atedat the ends of the extension 5 and support the same and give a finished appearance to the structure, besides being utilized for storage of station ery and kindred articles for literary use. The legs 2 are arranged around the table 1 at suitable points to provide a substantial sup.- port for the structure. trally disposed with reference to the table and library and bo0k-rack and comprises a lower portion 6, reduced at its upper end and made angular to fit in an opening of corresponding shape provided at the center of the table and an upper portion 7, made rounding and constituting a spindle upon which the library and book-rack are mounted for rotation. The reduced portion 8 of the post 3 has an outer shoulder at its base, which underlaps the table and forms a. support therefor, whereas the upper end of said reduced portion is about flush with the top of the table 1 or projects slightly therearound to sustain the center portion of the library or revolving book-rack.

The library or book-rack 9 is of circular form and has a vertical opening at its center to receive the upper or spindle portion 7 of the center-post 3. The book-rack or library may be of any diameter and comprise any number of tiers of shelves, according to the size of the structure. The shelves 10 are preferably of circular outline and are spaced apart a distance according to the height of the books to be placed between them. The space between adjacent shelves is subdivided into compartments 11, which are adapted to receive books, said compartments being of any depth and having their vertical walls parallel. The spacing portions 12 between the compartments 11 serve to hold the shelves the required distance apart and likewise to space the books laterally, so as to form the parallel-sided compartments 11, which otherwise would have their vertical walls outwardly diverged, thereby permitting the books placed upon the shelves to be spaced upon their outer portions while cramped upon their inner portions. It will thus be understood that the spacing portions 12 perform a dual function. The spacing elements 12 may consist of blocks or may be formed in any manner; but it is preferred to construct them of sheet material bent into the form substantially as shown in Fig. 4, the

Patented July- 10, 1906; V

The post 3 is censheet material being provided in a strip which is alternately bent backward-and forward upon itself to provide the side and inner walls of the book-receiving compartments and the outer spacing portion coming between the adjacent compartments. Tierods 13 connect the shelves 10 in series and serve to clamp them and the spacing portions together, said tie-rods being arranged in the angles formed between the side walls of the compartments 11 and the'outer spacing parts 12. The employment of a strip in the formation of the compartments and spaced portions between said compartments results in the formation of an exceedingly light and cheap structure.

To increase the efficiency of the structure, upright portions 14 are extended vertically from the-ends of the extension 5 and are provided with compartments to receive stationery or sundry articles, said compartments being either in the form of pigeonholes or provided with drawers, as may be determined upon.

' The library or book-rack is rotatably 2 mounted upon the table 1, and to minimize the friction between them antifriction-bearings 14 are interposed between said parts and in the present instance consist of' rollers mounted upon pins fitted to the table in any manner.

Having thus described the invention, what is claimed as new is In a rack, the combination of "spaced shelves of substantially circular form, a strip bent alternatelyback and forth upon itself to provide spacing means for subdividing the space between said shelves into a plurality of compartments, the latter having their approximately radial Walls substantially parallel, and connecting means for securing the shelves and spacing means.

In testimony whereof I aflix my signature in presence of two witnesses.
