PROVISIONAL SPECIFICATION.
Improvements in Rolling Appliances for Facilitating the Movement
of Weights.
I, EDWIN BARRON of 12 Magdala Road Junction Road London N. Commission
Agent do hereby declare the nature of this invention to be as follows :-
My invention relates to a new and improved construction of pivot or swivel roller
and ball supports to be used instead of castors for carrying the weight of furniture
and for other purposes, so that each such support may have freedom of movement in
any direction upon and over the supporting surface and so that when that surface is
level the centre of resistance of such surface may be in the vertical line of pressure
imposed upon it by the weight.
In carrying out my invention I use in each support three rollers with horizontal
spindles inclined to each other at ungles of 60 degrees and mounted in a suitable
frame. The rollers may be free to rotate upon these spindles in which case the
spindles are made fast to the frame or otherwise the spindles may be made fast
to the rollers in which case they are left free to rotate in suitable bearings in the
frame. The frame thus connected with the three rollers is attached by means of a
vertical spindle (around or upon which it is free to revolve) to a socket or plate or
other device for receiving the weight to be supported. This weight may be trans-
mitted to the three rollers by means of this central vertical spindle or other device
provided for receiving the weight and transmitting it to the horizontal spindles―
The rollers may be spherical or frustrums of spheres and rest directly upon the
supporting surface. In some cases I place a ball or sphere below and in contact with
the three rollers such ball resting upon the supporting surface and retained in its
proper position by any suitable device.

COMPLETE SPECIFICATION.
Improvements in Rolling Appliances for Facilitating the Movement
of Weights.
I EDWIN BARRON of No. 12 Magdala Road, Junction Road, London, N., Com-
mission Agent 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 :-
My invention relates to an improved construction of pivot or swivel roller sup-
ports to be used instead of castors for carrying the weight of furniture and for
other purposes so that each such support may have freedom of movement in any
direction upon and over the supporting surface and so that when that surface is
level the centre of resistance of such surface may be in the vertical line of pressure
imposed upon it by the weight.
In carrying out my invention I use in each support three rollers having central
spindles with or upon which the said rollors may freely revolve such spindles being
so placed that their centre lines or axes shall be in one horizontal plane and inclined
to each other at angles of 60 degrees, or thereabouts and upon which spindles the
vertical weight is carried by means of a suitable frame holding or supporting the
spindles.
The rollers may be so made as to revolve upon and about central spindles fixed
rigidly to the said frame or otherwise central spindles studs or trunnions may be
fixed rigidly to or cast or made in one with the said roilers in which cases such

page_text: spindles studs or trunnions shall be 30 made as to revolve freely in suitable bearings
in the said frame.
The said frame thus connected with the three roilers is attached by means of a
pivot or swivel joint of any suitable construction to a socket or plate or other suitable
device for receiving and transmitting the weight or pressure to be sustained and
supported.
The rollers may be spherical or frustrums of spheres and rest directly upon the
supporting surface.
In order that my said invention may be fully understood I will describe the same
by reference to the accompanying drawing which represents an example of my
improved appliance as aforesaid and I wish it to be understood that although I have
for the sake of simplicity herein, described and assumed the weights loads or pressures
to be vertical and downward in direction and the supporting or resisting surface to be
horizontal I do not confine myself to this particular disposition of pressure and
resistance for the resisting surface may be inclined at any angle with the horizon.
But in all cases my invention provides that in each support the direction of the
pressure may be in one and the same straight line with the direction of the resistance.
and such line perpendicular or normal to the resisting surface.
Referring to the annexed sheet of drawings figures 1 and 2 aro elevations taken in
different directions respectively of one support made according to my invention.
Figure 3 is a sectional plan of the same in the plane A-A of figures 1 and 2 ;
figure 4 is a vertical section of the same in the plane B-B with two of the rollers
removed.
The same letters of reference upon the several drawings and views indicate similar
parts.
a, b, and c, are the three rollers having central spindles a¹, 6', and c', about which
they are free to revolve. d is the frame holding or supporting all these spindles and
connected by means of the pivot e, with the socket f. The pivot e, may be made in
one with, or rivitted, screwed or otherwise rigidly fixed to the socket f, and forms
with the upper part of the frame d, a swivel joint.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An appliance for facilitating the movement of furniture and other bodies,
consisting of three rollers arranged in a pivotted frame and at equal distances apart as
and for the purposes set forth.
2. The combination of the rollers a, b, and c, the spindles a', b³, and c¹, and the
frame d.
3. The combination of the rollers a, b, and c, the spindles a¹, b¹; and c', the frame d,
the pivot e and the socket f, as and for the purposes herein set forth.
Dated this Thirtieth day of January 1880.
