page_text: GEORGE CLARK, 8 New John Street, Bedminster, Bristol, Warehouseman, do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in castors and has for its object a means to
diminish the friction in same when in use.
My invention is constructed as follows:-
The castor I make in two portions. The lower portion I may make solid or if
preferred I may make same hollow with a solid top. This lower portion may be
provided with the ordinary wheel as at present in use. In this solid top I
form in any suitable manner, a ball race in which runs any suitable number
of balls.
The top portion is made partly hollow for the reception of the leg of the table,
sofa, or other article to which my invention may be fitted and the bottom of this
upper portion may be made solid or with a solid inward flange. This solid portion
may have a ball race cut or otherwise formed in same for the purpose of completing
the run in which work the balls aforesaid, or it may, if found desirable, be left flat.
The usual pivot may be employed on which the whole can revolve.
Dated this 11th day of January 1895.
