County of Middlesex, for the Invention of "IMPROVEMENTS IN FURNITURE
CASTORS." A communication from abroad by Pierre Edouard Verschave, of
Paris, France, Manufacturer.
Sealed the 11th February 1879, and dated the 18th September 1878.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at the
Office of the Commissioners of Patents on the 18th September 1878.

"IMPROVEMENTS IN FURNITURE CASTORS." [A communication from abroad by
Pierre Edouard Verschave, of Paris, France, Manufacturer.]
According to the present Invention the fork or bracket carrying the wheel of the.
castor is formed in one with or fixed rigidly to the swivel pin, which is free to
revolve in the plate fixed to the furniture instead of the swivel pin being fixed to
such plate, and the fork revolving freely thereon as heretofore. The pin is
surrounded inside the recess in the furniture by a tube of copper, brass, zinc, or
other metal, which is, preferably, secured rigidly to the plate, the upper end of
the pin being rivetted over its upper end, but so that the pin can revolve freely
therein. The tube may however be loose from the plate.

CHARLES DENTON ABEL, of Southampton Buildings, in the County of Middlesex.
IMPROVEMENTS IN FURNITURE CASTORS." A communication from abroad by
Pierre Edouard Verschave, of Paris, France, Manufacturer.
According to the present Ivention the fork or bracket carrying the wheel of the
castor is formed in one with or fixed rigidly to the swivel pin, which is free to
revolve in the plate fixed to the furniture instead of the swivel pin being fixed to
such plate, and the fork revolving freely thereon as heretofore. The pin is
surrounded inside the recess in the furniture by a tube of copper, brass, zinc, or
other metal, which is, preferably, secured rigidly to the plate, the upper end of
the pin being rivetted over its upper end, but so that the pin can revolve freely
therein. The tube may however be loose from the plate.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a side elevation of the improved castor; Fig. 2 shows a front view
of the same, secured to the furniture; and Fig. 3 shews a sectional plan.
The stem or pin A, and fork or bracket B are formed of one piece, or fixed
rigidly together by soldering or otherwise, so that the stem turns with the fork
instead of the latter turning loose upon the former, as is the case with ordinary
castors.
For guiding the stem in the furniture a tube or socket c, by preference of drawn
copper, is fitted over it, and secured by a disc D, which is screwed to the furniture,
and thus fixes the castor, the upper end of the stem being rivetted over the end of
the socket so as to prevent it from coming out.
The tube or socket c may be of other material than copper, such as iron or zinc ;
it may be either drawn solid or be of sheet metal bent into cylindrical shape, with
the meeting edges soldered together or left open, as shewn at Fig. 4. It may be
either loose from the disc D, or by preference, it is fixed thereto, as shewn in
elevation, vertical section, and sectional plan, at Figs. 5, 6, and 7, where the tube a
is fixed to the disc b, either by soldering, screwing, rivetting, or other means.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, as communicated to me by my foreign correspondent,
I claim in respect of furniture castors,-
First. Constructing the stem or pin of a solid piece with or fixed rigidly to the
fork or bracket, so as to revolve with it, substantially as herein described.
Second. The use in combination with the revolving stem or pin referred to in the
preceding claim, of a tube or socket surrounding the same, such tube being either
fixed to or loose from a disc or plate, that is, secured to the furniture.
In witness whereof, I, the said Charles Denton Abel, have hereunto set my
hand and seal, this Sixth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
