COMPLETE SPECIFICATION.
Improvements in Revolving Book Cases, Docket File Cases,
Cabinets, or the like.
We, BENJAMIN MICOU of 1925 F Street, N.W., Washington, in the District of
Columbia, United States of America, Chief Clerk, Navy Department, and GEORGE
CROGHAN REID, of The Marine Barracks, Washington, in the District of Columbia,
Major, United States Marine Corps citizens of the United States, 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:-
This invention relates to improvements in revolving book cases, docket file cases,
cabinets and the like intended to hold books, files, or other like articles, and the said
invention consists in providing for the said revolving case a suitable anti-friction or
roller base bearing, so constructed as to dispense with the central vertical pivot
usually employed with similar revolving book cases or the like, whereby, greater
stability of structure, ease of operation and economy of space may be obtained.
The invention will be understood by reference to the accompanying drawings,
wherein like parts are indicated by similar letters.
Fig. 1 is a side elevation of the improved revolving cabinet adapted to contain
files for a business office.
Fig. 2 represents a perspective view of the base of the cabinet shown in Fig. 1,
the cabinet being detached from the pedestal.
Fig. 3 represents a perspective view of one form of pedestal upon which the
cabinet may be mounted, and
Fig. 4 represents a sectional elevation of the ring on the base of the cabinet and
of the roller supporting the same and the contiguous parts.
A represents the body of the cabinet, which may be of any preferred or desired
shape, and may be provided with docket panels a, or larger panels a' or shelves or any
other suitable arrangement of parts for stowing away books, papers, articles to be
exhibited, or other articles.
B represents a ring secured to the base of the cabinet as shown in Fig. 2. This
ring may be made, of a single casting, but it is preferably made in two parts for
convenience in mounting the cabinet, and these two parts may be secured together
As at b. The ring is flanged as at bi and secured to the bottom of the cabinet, and
is provided with a bearing surface & to engage the rollers C, with a hook 6' to engage
under the lugs F', and with an inclined surface l° to bear on the similar surface co of
the rollers C.
If preferred, the flange b¹ may be on the interior and the hook on the exterior of
the ring B, the relative position of the rollers C and of the lugs F¹ being then
reversed.
The rollers Care preferably made with a hollow shell C closed by the nut C² which
is provided with the ball race ca similar to the ball race c¹ provided on the interior of
the shell C. A roller shaft D is provided with cone bearing surfaces d which
engage the rollers E, and the ends of the roller shaft are preferably diminished and
project through the openings of the roller shell and of the nut, respectively, and
rest on bearings f at the ends of the cruciform plate F. Lugs or projections F
project upwards and outwards (or inwards if the parts be reversed), from this
cruciform plate F and engage beneath the hooks of the ring B. This cruciform

page_text: plate F is secured to the base of the pedestal: G, which is preferably made of the
ordinary shape and may either rest. upon the floor or may be mounted upon
castors g.
The shape of this pedestal and of the plate F may be varied at will.
When the parts are assembled, the bearing surface 63 of the ring B rests upon
the bearing surface of the roller, while the conical face 6° of the ring bears gently
on the conical face co of the roller, and thus steadies the cabinet against motion
laterally, or in the direction of any of the radii of the ring. B.
It will be seen from the above construction that the book case or cabinet may
be readily revolved about its .axis and it is securely held against lateral motion and
also against tilting motion.
Should it be preferred, the ring. B may be made in one piece and the cruciform
piece. F may be made of malleable material, and the lugs F may be bent over to
engage beneath the hooks 6 of the ring B after the parts are in place.
Instead of the hollow. rollers. C as shown in Fig. 4, ordinary rollers may be used
if desired..
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :
1. A revolving book case, cabinet, or the like, provided with a roller base bearing;
adapted to support the same against lateral motion and also against tilting motion,
substantially as herein described and shewn in the drawings hereunto.annexed.
2. The combination, with a case, or cabinet proper,. of. a ring, adapted to be
secured to the base of the same, and having a lateral flange or shoulder, and a.metal
base frame, having lugs, one of which is extended to form a hook that
the
ring shoulder, and flanged rollers journalled in said lugs, whereon the lower edge of
said ring rests and travels, substantially as described and shewn.
3. The combination, with the flanged ring, secured to the base, of the cabinet
proper, of the base frame having hollow. anti-friction rollers, and the lugs extended
upwards and forming hooks engaging said flanged ring, substantially as herein
described and shewn in the drawings hereunto annexed.
4. The cruciform bearing for a revolving book, case or cabinet, having, pairs of
integral vertical lugs at the end of each arm adapted to form journal bearings for
the rollers, one of each of which pairs of lugs: is extended and shaped into a, hook,
substantially, as herein described, and shewn in the drawings hereunto annexed.
