Improvements in Furniture Castors.
HENRY DANIEL BOOTH 10 Trigon Terrace Fentiman Road Clapham Road in the
County of Surrey Wood Turner do hereby declare the nature of this invention to be
as follows:-
The construction of Castors by means of a Ball or Roller with holo drilled through
the centre which receives a loose axle pin to which axle pin are attached two small
wheels loose one on each side of axle pin. The Top portion of Castor has a recess
which receives the Ball or Roller loosely and leaves a plate for the two wheels to run
on. This recess is on the underside of the said portion of Castors, the Wheels Ball
(or Roller) and pin are kept in position by the screwing or fixing of a cap or shell on
the top portion of Castor, the cap or shell having on its underside a recess through
which the ball protrudes, the cap or shell is so fixed to give free action to Ball axle
pin & wheels.
This Castor can be made as socket or screw & is fixed in the ordinary way.

London S.W. in the County of Surrey Wood Turner 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:-
The object of my invention is the construction of a Castor having a Ball or Roller
with hole drilled (or by any other method) through the centre which recieves a loose
Axle Pin to which Axle Pin are attached loosely two small wheels one on each side
of Axle pin. The Top Portion of Castor is made with a recess which recieves the
Ball or Roller loosely which leaves a plate for the action of the two small Wheels.
The Wheels Ball & Axle Pin are kept in position by the screwing or fixing on of a
Cap or Shell the Cap or Shell having on its underside a recess through which the Ball
or Roller protrudes. This Cap or Shell is fixed or screwed to give free action to Ball
Axle & the two small Wheels.
In carrying out my invention I use a Ball (or Roller of hard substance such as
Brass Iron steel Glass China Wood Composition &c. hollow or solid.
Fig. 1. shews the Ball & section letter A shews hole through its centre for the
reception of the Axle pin.
I also use an Axle P'in plain or with shoulders as shewn in Fig. 2.
I also use two small wheels as shewn in Fig's. 3 & 4 these I may also make Ball
shape.
I also use Fig. 5, which is the Top Portion of Castor and the portion to be
fixed to the article of Furniture. This can be done by a fixed central screw or by
Ecrewing an ordinary screw through section B, this may also have other drilled holes
for more screws or pins or it may have fixed pins on its topmost side to aid its
attachment to articles of Furniture, as shewn this portion of Castor is made with a
recess for the reception of Ball (or Roller) loosely and thereby is left a marginal plate
for the action of the two wheels.
I also use a Cap or shell as shewn in Fig. 6, this I screw or fix to the Top portion
Fig. 5 and as it is made with a recess the Ball (or Roller protrudes through and
comes in contact with the ground.
Having dealt with each piece separately I now explain how they are used as shewn
in Fig. 7.
The Ball Fig. 1 recieves Axle Pin Fig. 2 through section A, I then attach loosely
one on each side of Axle pin the two wheels Figs. 3 & 4, I then place them in the
cap Fig. 6 and screw or fix the cap to the Top Portion Fig. 5 Fig. 5 being already

page_text: fixed to the article of Furniture, in fixing or screwing the cap or shell I allow free
action for the Ball Axle & Wheels.
The Ball protruding through the recess on the underside of the said cap or shell
comes in contact with the ground. By this construction a Castor is obtained with
upright direct bearing easy to repair or clean simplicity of action which answers to
every movement required in the removal of pieces of Furniture from place to place.
Fig. 8 shews Castor Finished. This can be made as a socket, plate, or any known
description of Castors.
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 :—
1. The construction of Castors with a loose Ball (or Roller) with hole through its
centre, a loose Axle pin passing through the hole in Ball or Roller & two small wheels
of any shape which I attach loosely one on each side of Axle Pin.
2. The Top Portion of Castor with recess and marginal plate on its underside.
3. Keeping the same Ball (or Roller) Axle Pin & Wheels in Position with free
action by screwing or fixing a cap or shell to the Top portion mentioned previousley
securing thereby the double action nesscessary for the removal of pieces of Furniture
from place to place with a direct upright bearing.
