ALFRED WEBB of 54 Vicarage Road Aston in the County of Warwick Manager
and Pattern Makeriao hereby declare the nature of this invention to be as follows:-
In forming a groove in the bottom of the socket, or in the top of the Wheel-Carrier, or
in both as I find most convenient, in placing in the grooves so formed Discs, "or spheres
may be used instead," I place as many as will fill the grove causing the projecting
faces to touch each other. And, placed in the bottom of grooves are steel or other
suitable plates, upon which the Discs, or Speres revolve.
The Socket or plate which is screwed upon the furniture by means of a centre screw
or other suitable screws is connected to the horn that carries the wheel by means of an
axle pin, rivited or screwed at one or both ends. Discs or Spheres are placed in
grooves, the Socket or plate bearing upon the top of the discs, the horn or wheel
Carrier upon the bottom of them allowing the Discs to revolve freely round the
axle pin.
Castors constructed upon these principles will allow any article upon which they are
placed to move in any given direction with the least pressure. This great freedom of
action, and absence of friction, will allow the axel pin in the horn upon which the
bowl is fixed to be placed in a centre line with the axel pin connecting the horn with
the socket, thus dispensing with the leaverage caused by placing the axle pin of the
bowl out of the centre line of bearing.
This I claim to be one of the meritts of the invention.
That Castors constructed on these principles give an equal & direct bearing.

page_text: I ALFRED WEBB now of 66 Burlington Street Aston in the County of Warwick,
Pattern Maker and Manufacturer do hereby declare the nature of this invention and
in what manner the saine is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
In forming a groove in the bottom plate of the socket or in the top of the wheel
carrier or in both as 1 find most convenient. In placing in the grooves so formed a
number of Discs Roolers or Speres I place as many as will fill the grooves, causing
their projecting faces to touch each other the socket or plate is secured upon the
furniture by means of a central or other suitable screws, and is connected with the
horn that carries the Wheel by means of an axle pin rivited or screwed at one or both
ends. Roolers or spheres are placed in the grooves, the socket or plate bearing upon
the top of the bottom of them, allowing them to revolve freely round the axle pin.
Castors constructed upon these principles will allow any article upon which they are
placed, to move in any given direction with the least pressure. This great freedom of
action, and absence of friction, will allow the axle pin in the horn upon which the
bowl is placed, to be made nearly in a centro line with the axle pin connecting the
horn with the socket.
I place in the socket grove, steel or Iron Washers when extra strength is required.
Fig. 1, shews the castor complete.
Fig. 2, is a section shewing the rooler or spheres, a, placed in the groove b.
Fig. 3, is a plan of the socket, c, shewing the roolers and spheres, a, placed in the
groove, b.
d is the centre hole through which the axel pin, C, is passed connecting the socket, c,
with the horn or wheel carrier f, the axel pin, G, carries the bowl, H.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is
Firstly, the placing of Discs rolers or sphers in suitable grooves between the
sockets or plates and the horn of the castor. In placing in the grooves steel or iron
washers.
Secondly, that castors constructed as shewn by these Specifications and drawings
removes all leverage from the axel pin connecting the horn and socket and has a
direct bearing in all working positions.
