' -llMPROVEMENT IN REVOLVING BQOK-CASES.
Specification forming part of Letters Patent No. 177.479,' dated May 16, 1876; application filed April 13, 1876. V.
. v To all whom ltmcy concern:
Be it known that 1, JOHN BANNER, of Ganton, in the county of Stark and State Ot' Ohio, have invented certain new and useful lm provements in Revolving Book-Cases; and that the following is a full, clear, and exact description of the construction and operationvof the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents, in perspective, one of my improved revolving book-cases. Fig. 2 represents a vertical central section through the same. Fig. 3 represents a vertical section through two contiguous shelves of one of the series, showing the manner in which they are supported and have their joints covered. Fig. 4 represents, in perspective, the conical spindle and its bearing employed to support the bookcase, and keep the frictional parts lubricated.
Similar letters of f reference, where they occur, denote like parts in all the igures.l
I am aware that revolving book-cases have been made to rotate around a spindle located within its frame, but the difficili ty has been to reduce the friction and noise produced, under the pressure or weight of the books, by the contact of the movable and stationary parts. For this purpose friction-rollers have been used upon the frietional parts, but often they only increase the noise, and when lubricants are used, they cannot be renewed without taking the framing to pieces, or, if an oil-hole is located so as to reach the bearing parts, it must be located where the books are likely to be injured by the oil.
The object of my invention is to produce a revolving book-case that, by its construction, will render the use of friction-rollers unnecessary. It being suspended from the top of a central-post extending to the top of the book: ease, it possesses a degree of stability that could not be obtained by any other modeof construction. And my invention relates to the combination, with thesaid suspended bookcase and its central post, of a perforated pendent spindle attached to the upper part of the book-case, and a conical oil-cup bearing attached tothe upper extremity of the post, and an oil-duct, by means of which the frictional parts can ,easily be kept lubricated without danger to the books. My invention further relates to the mode of constructing and sup,
' porting the shelves of my suspended revolving tached to vertical rods suspended from horizontal guide-rods.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.
A represents a vertical quadrangular hollow prism, to which are attached the horizontal bars B that support the inner end of the shelves G of the bookcase, while the outer end is supported by vertical strips D suspended from the top shelf C. As all the boards that form this top shelf can extend across the horizontal bars B, it can be made of any desired strength. However, it is provided with a rim, c', on its Linder side, to add to its strength, and keep the top shelf from warping. The lower series of shelves are als'o provided with a rim, c', to add to their strength, and to improve the appearance of the book-case, the rims c and c presenting more surface to fasten the connecting vertical strips D to the top and bottom shelves. To the rims c and c are attached the horizontal rods d, supporting the curtain E, used to inclose the book-case, if desired. This curtain is preferably fastened to vertical rods e, having screw-rings f at each of their extremities resting upon the rods d. The rods d are bent at a right angle at d', where they form a rest for the screwrings f, and retain the curtain E in a stretched position. To the under side of the top shelf G is attached a pendent conical spindle, g, that rests in an oilcup bearing, h, attached to the top of a cylindrical post, F, that is kept in a vertical position by legs G, attached to it near its lower extremity. These legs can be made either of wood or metal, and can also be provided with caster-wheels. The v pendent spindle g is provided with an opening, g', to receive oil for the bearing. A duct, i, is located over it in the top shelf G', and a cap or cover, 7c, is placed over the duct i to exclude the dust. The intermediate series of shelves (of which there may be as many as desired) between the 'top and bottom shelves are supported at their inner ends by the ,transverse bars -B,and jat their outer endsby'the vertical strips D, that also keep the books in their places upon the shelves. To strengthen the bookcase, and to give it a better finish, and also to form a stop for the books, I attach tothe prismA, and resting on the shelves, a series of'horizontal bars, B', that cover all the joints in the shelves, and preserve the binding. of the. ,-booksfronrr injury against the sharp edges of the joints. The revolving book-case is connected to the central post F by means of a collar, m, formed of two pieces that embrace the post in an annular groove, n.
It is evident that a very convenient ward. robe can be constructed in the same manner as above described by simplyomitting the inter-VA mediate shelves between the'top and bottom of the revolving case, and the curtairrldlsur-- rounding it Will form all the covering required. If Ithe revolving bookcaseis-madelow, with only a couple of shelves, itwill'4 be found-veryg convenient asv vvaftable fora study," and it can then be finished With a marble top, or otherwise.
Having now described my invention, what I claim is- 1.7Incombination with a revolving bookcase, suspended `from the top of a stationary post, having an oil-cup bearing, h, the pendent spindle "gh-attached' to the top shelf of the frame, and oil-duct constructed substantially as and for the purpose described.
2. In combination lWithla revolving bookcase, suspended from the top of a stationary post, F, the series of horizontal bars B', and
.vertical strips l), to cover the joints of the shelves and support them, substantiallyL as shown and described;
