We, THE SIMPLEX CASTOR SYNDICATE LIMITED, of 28, Gracechurch Street,
in the City of London, Merchants, and JOHN CHARLES CRAMPIN READ, of
290, High Holborn, in the County of London, Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in casters for furniture and other articles.
and of the kind wherein a spindle or its equivalent works within a casing or sleeve
and has for its object improved means for connecting the spindle to the casing.
According to our invention we form the spindle or its equivalent with projections
or with a flange at its upper end, the said projections or flange being adapted to
fit into the upper end of the outer casing which is enlarged to receive the same.
To connect the spindle or its equivalent to the casing we provide the enlarged
portion of the outer casing with a screw-thread, either internal or external, and wa
screw outo or into the said casing a ring, the upper edge of which is turned
inwards forming a flange which fits onto the projections or flange on the spindle or
its equivalent thereby connecting the latter to the outer casing.

We, THE SIMPLEX CASTOR SYNDICATE, LIMITED, of 28 Gracechurch Street,
in the City of London, Merchants, and JOHN CHARLES CRAMPIN READ, of
290, High Holborn, in the County of London, 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 improvements in casters for furniture and other articles
and of the kind wherein a spindle or its equivalent works within a casing, sleeve
or socket and has for its object improved means for connecting the spindle to the
casing or socket.
According to our invention we form the spindle or its equivalent with projections
or with a flange at its upper end, the said projections or flange being adapted to fit
into the upper end of the outer casing or socket which is enlarged to receive the
same. To connect the spindle or its equivalent to the casing or socket we provide
the enlarged portion of the outer casing with a screw-thread either internal or
external, and we screw onto or into the said casing a ring, the upper edge of which
is turned inwards forming a flange which fits onto the projections or flange on the
spindle or its equivalent thereby connecting the latter to the outer casing.

page_text: To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing which represents a vertical section of our
improved caster.
a is the casing or sleeve forming the socket of the caster, and b is the caster
wheel which is mounted at one side of the vertical axis of the socket to permit of
the caster wheel readily taking the direction in which the piece of furniture or the
like is being moved, in a well known manner, the said socket being bored out
internally to a conical form.
c is the conical spindle which fits within the socket at its upper and lower ends
and turns freely therein, the said spindle being made hollow so that it may be
fitted onto the leg of a piece of furniture or the like, the leg in the drawing being
indicated by the letter d.
ee are the projections or flange which we form at the upper end of the spindle c;
fis the enlargement at the upper end of the casing or socket a, such enlargement
forming a seating for the projections or flange e; g is the screw thread on the
enlarged portion of the casing or socket a, and h is the ring adapted to screw onto
the casing or socket in order to connect the spindle c thereto. i is the flange formed
on the upper edge of the ring by turning the same inwards, the said flauge fitting
onto the projections or flange e on the spindle, thereby connecting the spindle to
the casing a.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a caster in which a spindle or its equivalent works within a casing, sleeve
or socket, a ring screwed onto the upper end of the said casing or socket and
projecting over a flange on the spindle for preventing the casing or socket and
spindle from becoming separated, substantially as described.
2. The improved caster hereinbefore described and illustrated in the accom-
panying drawing.
