PROVISIONAL SPECIFICATION.
An Improvement in Revolving Bookcases.
I, CHARLES JAMES WICKS, of 14 Queen Caroline Place, Dinmont Street,
Hackney Road, in the County of London, England, Cabinet Maker, do hereby
declare the nature of this invention to be as follows:-
A metal bearing either of brass, gun-metal, or iron. The same consists of a
metal socket, and a flange collar, the object of which is to prevent the revolving
portion of bookcase becoming loose, & for this purpose, I fasten the socket to the
vertical pillar that is attached to the stand of bookcase, and the flange collar I
fasten to the upper portion of bookcase, directly beneath the square cylinder of
case.
The socket fits inside the flange collar, & takes a bearing on the flange.
I do not confine myself to size, that depending upon the weight and size of
bookcase.

An Improvement in Revolving Bookcases.
I CHARLES JAMES WICKS of 14 Queen Caroline Place, Dinmont Street,
Hackney Road, in the County of London, England, Cabinet Maker, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Hitherto, it has been the practice to manufacture revolving bookcases without
making proper provision for preventing the "uper portion" from working either
too loosely or tightly in the underframe, this is caused either by the constant wear
when it is revolved, or the shrinkage of the wood.
The object of my invention is to provide suitable means to overcome these
disadvantages, and allow the bookcase to be easily and steadily turned.
But in order that my invention may be better understood I will now refer to the
accompanying sheet of drawings which are to be taken as part of this Specification
and read therewith.
Figure 1, is a sectional elevation of a revolving bookcase, and
Figure 2 is an enlarged detail view of my improvement.
Similar letters of reference indicate similar or corresponding parts where they
occur in both views.
In the drawings (A) is the ordinary bookcase having suitable shelves similar
to (B), (C) is the stand to which is secured the pillar or pedestal (D) carrying the
bearing (E) for supporting the bookcase; (F) is a square cylinder, and (G) is
the underframe.
Now my improvement consists in securing to said underframe (G) of the
bookcase, a metallic flanged collar (H) which fits over a metallic sleeve (I)
fastened on to the lower portion of the pillar or pedestal (D). Said sleeve (I) is
provided with a shoulder (J) that prevents the bookcase from being lifted off the
stand.

page_text: The method of attaching my improvement is as follows:-
The flanged collar (H) is first fastened, by means of screws, to the underframe (G)
and is then fitted over the sleeve (I) which is secured in position upon the pillar (D),
after which said underframe is attached to the bookcase in the usual way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
In revolving bookcases, the combination and arrangement with a pillar or
pedestal (D), of a sleeve (I) which engages with a flanged collar (H) secured to
the underframe (G), as and for the purposes herein described and as illustrated
in my drawings.
