PROVISIONAL SPECIFICATION.
Improvements connected with Furniture Castors."
I, MICHAEL JOHN ROWLEY, of 14 Blandford Street Portman Square, County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements connected with Furniture Castors.
For the purpose of my invention, I form the interior of the upper half cup
with a recess for holding a plate in which a series of rollers, say, three are
pivoted equa distant and against which the Castor ball is in in contact, said ball
being retained loosely in position by a lower cup or collar which can be screwed
or secured to the upper cup.
In lieu of the rollers, a series of bearer balls can be fitted in a circular channel
in the plate for the Castor ball to roll against and so reduce friction.

I, MICHAEL JOHN ROWLEY, of 14, Blandford Street, Portman Square, 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 connected with Furniture Castors.
For the purpose of my invention, I form the interior of the upper half cup
with a recess for holding a rotatable plate having a series of rollers, say, three
pivoted equa distant and against which the Castor ball is in contact, said ball
being retained loosely in position by a lower cup or collar which can be screwed
or secured to the upper cup.
In lieu of the rollers, a series of bearer balls can be fitted in a circular channel
in the plate for the Castor ball to roll against and so reduce friction.
My invention will be clearly understood by reference to the annexed drawings.

Figures 7 and 8 views of Castor affixed to, say, the leg of a Chair and Piano
respectively.
A, socket. A¹, base. B, plate lodging in under part of upper half cup C and
located by ring 1) or on ball bearings E for free action and reduction of friction.
F, F, F, three rollers in frames G, G, G, each frame being pivoted in or to the
plate B and with the faces of the rollers coinciding or nearly so to the spherosity
of the main ball H for equalization of touch said ball H being retained loosely
in position by the lower half cup I secured to the upper half cup by the screw
as shown, or otherwise.
Having now particularly described and ascertained the nature of this inven-
ti. n and in what manner the same is to be performed I declare that what I
claim is:-
The hereinbefore described improvements connected with Furniture Castors
in which the main ball H bears in contact with rollers F, F, F, having swivel or
pivoted frames G of a plate B so arranged in the unner half cup C that freedom
of rotation is possessed by all the fitted in parts to follow or yield to all the
movements of which the ball H is capable, all as set forth and shown in the
annexed drawings.
