I BENJAMIN LANGFORD FORSTER POTTS of 55 Chancery Lane, London in the
County of Middlesex, Civil and Mechanical Engineer, do hereby declare the nature of
this invention to be as follows :-
This invention relates to the form and construction of cabinets for containing books,
papers, tools, bottles and other articles. Such cabinets consist of one or more
receptacles arranged to turn round a vertical axis. For use as a receptacle for books
I employ a double set of shelves arranged in an upright case of rectangular form in
such a manner that it shall contain two sets of shelves on which the books are placed
face to face. This case is mounted so as to turn easily on a vertical spindle or on
pivots at top and bottom. Two sides of the rectangular case are closed in by wood or
metal and either of them serves as a door to close the bookcase. Each vertical case
has its spindle or pivots placed within a fixed outer casing at such a distance from its
front as shall allow one of the closed sides of the revolving receptacle or one of the
sets of book shelves to come into a line with the front of the fixed outer casing when
the revolving receptacle is turned, thus either closing the casing or exposing one or
other of the sets of book shelves at pleasure. The revolving receptacle may be
secured in either position by a lock or catch. The revolving receptacle may be
provided with drawers or pigeon holes as well as with shelves.
The revolving receptacle may be made of a square, circular, triangular or polygonal
form in cross section and a number of such receptacles may be arranged side by side
or in a circle within an outer fixed casing. The revolving receptacles may be adapted
to writing tables or other pieces of furniture. For containing bottles or similar
articles or tools I employ a modified form of cabinet in which I arrange a number of
circular or polygonal receptacles one within the other and all revolving round a fixed
vertical spindle; each of these receptacles is provided with compartments for the
reception of the bottles or other articles which articles may be removed from the
compartments of the inner revolving receptacles through an opening or openings in
the outer revolving receptacles each such receptacle being turned when necessary to

page_text: bring a fresh compartment opposite the opening after the removal of a bottle or other
article. By this means I am enabled to remove or replace any particular article
without removing any other from the receptacle. The revolving receptacles may be
enclosed within a fixed outer casing which may be closed by a hinged, sliding or other
door which may be secured by a lock or other fastening. The revolving receptacles
may also be secured in position by a lock or bolt.
A modified form of cabinet may consist of a rectangular revolving receptacle
provided with drawers or pigeon holes or both, and around such rectangular
receptacle compartments may be arranged for the reception of bottles or other
articles. The receptacle is arranged to turn on a vertical axis within a fixed casing.
By turning the receptacle round, the drawers will be at one time presented to the
opening in the fixed outer casing and at another time the compartments containing
the bottles or other objects will be presented in succession to such opening. When in
the position in which the drawers are opposite the opening, the receptacle may be
secured by a lock or other fastening the fronts of the drawers then forming a door to
close the opening in the fixed outer casing.

I BENJAMIN LANGFORD FORSTER POTTS, of 55 Chancery Lane, London in the
County of Middlesex, Civil and Mechanical Engineer, 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 the form and construction of cabinets for containing books,
papers, tools, bottles and other articles.
The cabinets consist of one or more receptacles arranged to turn round a vertical
axis and when used for containing books, papers &c. such cabinet may be made in the
form shown in Figs. 1 to 9 inclusive on the accompanying sheets of drawings, on.
which similar letters refer to similar parts.
Fig. 1 is a front elevation, Fig. 2 a vertical cross section and Fig. 3 a horizontal
section of a cabinet containing two revolving receptacles B, B¹ mounted so as to
rotate on pivots a. b. at top and bottom, within a fixed outer case A. The vertical
revolving receptacles may contain two sets of shelves on which books may be placed
face to face. By revolving the receptacles the backs of the books on one set of shelves
or the other may be turned to the front; or the outer casing A may be closed by one
of the sides of the revolving receptacles B. B¹ as shown on Fig. 3.
Fig. 4 is an elevation, partially in section, and Fig. 5 a sectional plan of a modified
form of cabinet for books, papers &c. in which two revolving receptacles B. B₁ are
arranged to rotate on pivots a. b. at top and bottom. These pivots work in bearings
carried by swinging frames c, e¹ which also turn in bearings d. d¹ at top and bottom
of the outer fixed case A. In this modification the receptacles B. B¹ have a forward
as well as a rotating motion, and the outer fixed casing A does not occupy so much
space as that shown in Figs. 1 to 3.
Fig. 6 is an elevation, partially in section, and Figs. 7 and 8 are sectional plans of
a modified form of cabinet for books papers &c. in which two revolving
receptacles B. B₁ are arranged so as to have a compound revolving and forward
motion being guided by cams e and fattached, at top and bottom, to the outer fixed
casing A. as shown on Figs. 6 and 8. The top and bottom of each of the revolving
receptacles B. B' are provided with four rollers, those at the top marked 9. and those
at the bottom marked g¹. These rollers work against the insides of the cams e, f, and
the lower rollers gl are provided with balls as shown on Fig. 9, to carry the weight of
the receptacles and enable them to move easily.
In order to allow of the rectangular revolving receptacles turning round in the fixed
outer casing A. the two ends of the said casing are mounted on hinges h. h¹ so that
the ends may swing out into the position indicated on Fig. 7 when the
receptacles B B are turned round. The hinged ends may be provided with springs
to keep them closed and they, as well as the receptacles, may be retained in position
by a lock, bolt, or other fastening.
Figs. 10 and 11 are front elevations, and Fig. 12 is a horizontal section of a
cabinet for containing chemicals, medicines, tools, pipes, dentists' instruments and
other articles in shops or private houses. In this cabinet a revolving receptacle B is

page_text: mounted to turn, on pivots at top and bottom, within the outer casing A. The interior
of the receptacle B is provided with a set of drawers C and the outside of the said
receptacle is furnished with shelves or compartments D for containing the bottles or
other articles, and these compartments may be closed with glass or other doors as
shown at Fig. 12. By turning the receptacle B round, either of the three sets of
shelves or compartments D or the set of drawers C may be brought to the opening in
the front of the outer fixed casing and may be secured by a lock or bolt in that
position.
Fig. 13 is an elevation, partly in section, and Fig. 14 is a sectional plan of a cabinet,
for containing bottles or other articles. In this arrangement three revolving
receptacles B, B', B' are employed, one within the other, and all revolving round a
fixed central spindle j. These receptacles are provided with a number of radial
compartments k, k¹, for containing bottles of the form shown, or other articles.
When in the position shown, a bottle may be removed from one of the compartments
of the inner receptacle B and by turning the receptacle round, any of the articles can
be removed, and by turning any compartment of the receptacles B¹ and B' towards
the opening in the outer case A, any article can be removed without disturbing any
other. The receptacles may be secured in any position by a bolt, and the opening of
the outer case A may be closed by a hinged, sliding or other door which may
be locked.
The receptacles and outer case may be made of wood or metal and may be made
fire and burglar proof.
The cases where the receptacles or their contents are heavy, a ratchet and pall,
worm and worm wheel, or other mechanical device may be employed to turn them
round.
The receptacles may be of a square triangular or polygonal form in cross section
and a number of them may be placed side by side or in a circle within an outer case,
and in some cases, the receptacles, or some of them, may be made to vibrate instead of
revolving.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is,
1. Arranging the movable rectangular receptacle within a fixed outer casing in
such a manner that any one of its sides may be presented to the opening in the outer
fixed casing.
2. Arranging the movable rectangular receptacles in such a manner that they will
have a compound revolving and backward and forward motion.
3. Arranging a number of movable receptacles, one within the other, in such a
manner that any article may be removed from any one of them without disturbing
any other article.
4. Arranging the ends or sides of the outer casing to swing out to allow the
movable rectangular receptacle to be turned round.
5. Arranging the movable receptacles within an outer casing, in such a manner
that the opening in the said case may be closed by one of the sides of the movable
rectangular receptacle.
