Improvements in Castors for Furniture and the like.
FREDERICK ARCHER SANDFORD FOALE, 8 Chesterton Road, North Kensington
London, W. Builder do hereby declare the nature of this invention to be as
follows:-
The introduction of ball-bearings, as shewn into castors, & also direct bearing.
Nos. 1 & 7 are elevations.
Nos. 2, 8 & 5 are vertical sections.
Nos. 3, 6 & 9 are plans of underneath side.
Nos. 4 & 10 are horizontal sections, 4 being through X X & 10 through Z Z.
A & B are drawings of two castors having the direct bearing. They may be
made with a round ball or an ordinary circular wheel with flat sides. A shews the
latter & B the former; as may be seen they will suit either.
E is a spindle made of hard metal, which runs through ball or wheel &icircular
plate D, & fixes ball or wheel into hole cut in D for it to revolve in. This spindle
is rivetted at both ends into circular plate as shewn in Sections 4 & 10.
D-the circular plate-has a circular groove on the top side which is filled
with shots or balls of any suitable metal. Section through X X shows it with
hole for ordinary wheel & section through Z Z with hole for ball.
:-
The
F is a tube made of brass or any other suitable metal. It has screw-holes in
the top for screws to fix into leg or support of anything it has to carry.
bottom end of F is made with groove which comes exactly over groove in D
taking the upper part of shots, thus forming the ball-bearing. On the outside of
the bottom end of F is a thread cut, which cap G screws on to thus keeping the
shots & plate in position.
B shews elevation, plan & sections of the ball-bearing castor with flat plate H
instead of ferrule for fixing.
1 is shewn as a screw with square head rivetted into H. It may also be a plain
pin without thread.
J is similar to the lower part of F in regard to thread & ball-bearings. It may
be rivetted through H as at K in 2 or more places.
C shews the ball-bearings action without direct bearing. In this case it is
necessary to have ball-bearings under as well as on the top of circulating plate L.
M. shews dotted spaces where N may be rivetted through L as at O.
P has screw holes for fixing similar to F. & has a hole through centre of bottom
through which Q passes & connects it to L.
Qmay be either a rivet as shewn or a circular pin rivetted into L, which
revolves round it & fixing into leg as at I.
This castor (C) can be made with flat fixing plate as at H, & with same bearings
as in C.
R is a cap similar to G but made stronger to take leverage made by wheel being
out of centre.
S is an ordinary circular flat wheel which may be made of any suitable
material.
T. is the pin on which S revolves. It is rivetted at both ends into N.
These castors may be made any size.
Dated this 9th day of November 1894.
Dated this in day of November 1094.

page_text: FREDERICK ARCHER SANDFORD FOALE 8 Chesterton Road North Kensington
London W. Builder, 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 improvements consist of a direct bearing wheel which revolves vertically, on
a hard metal pin-which runs through its centre & has its ends fixed in circular flat
plate as in A B & D, or in fork attached to flat plate as in C-& horizontally, by
means of flat plate turning round on ball-bearings.
A shews plau, elevation, vertical section & horizontal section through the centre
of wheel of castor-with wheel exactly in centre, with cup for fixing.
:-
E is the pin which runs through wheel G & flat plate F into which it is
rivetted at both ends & thus fixing wheel into hole cut in F for it to revolve in.
F, the circular flat plate, has a circular groove on the top side, which is filled
with shots or balls of any suitable metal. Sections A shew it cut out to take an
ordinary flat wheel, & sections B a circular ball.
His cast with large ferrule on top having screw-holes for fixing, & small cup
below for G to revolve in. It has circular groove ou bottom end, which fits
exactly over the groove in F, taking the upper part of shots, thus forming the ball-
bearings. On the outside of the bottom end of H is a plus thread, which cap I,
screws on to, thus keeping the shots & circular plate in position.
B shews elevation, plan & sections of castors with flat fixing instead of ferrule
as in A.
J is shewn as a plain pin rivetted into K, it may also be made with a screw
thread.
F in this case is cut out to receive a circular ball.
K is similar to lower part of H & has holes for screws for fixing in
upper part.
C shews the ball-bearing action with the wheel out of the centre, thus gaining
the extra leverage to make F revolve & yet keeping the weight spread evenly on
the leg on support to which it is fixed. It may have ball-bearings underneath, as
well as on top of circular plate F if necessary, by having a stouter screw cap with
circular groove cut to take bottom end of shots.
L is a screw which fastens into hole cut in bottom of M, to receive it, & is then
tapped with hammer to prevent unscrewing.
Fin this case can either be cast with fork in one piece of metal or may have the
fork rivetted through into it.
This castor may also be made with flat fixing plate, as in B.
D shews the same wheel with different fastening, this would be more suitable for
machinery or anything where it is necessary to keep the joint close.
N is cast with cup & circular hole to take ball or wheel & circular flat plate.
It has the circular groove on shoulder to take tops of shots. The flat plate is kept
in position by the face plate O, which has a circular raised portion which fits up
into hole.
O the face plate, may be fixed by means of rivets P, or may have a screw
thread turned round the raised portion, & a corresponding thread on the inside
of N, for it to screw on to.
Qare holes for screws to fix castor.
When these wheels are required to fix into metal supports whether leg of
bedstead, or flat iron plate, the holes could be cast in the support, with cup,
circular hole, & grooved shoulder complete, into which the wheel would be placed
& fixed by a face plate, as shown in D castor.

page_text: These wheels may be fixed in other ways than those shewn, they being only a
few examples, & may also be made any size & of any suitable material.
The vertical wheels may be made with the outside edge hollowed out all round,
as shown by dotted lines at R, also with spokes instead of being solid.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed 1 declare that what I
claim is:
1. The ball-bearings applied to castors.
2. The direct bearing wheel in conjunction with ball bearings also wheel as in
castor C.
