"Improvements in and connected with Furniture Castors."
I, WILLIAM TIMMINS, of 10, Soho Square, in the county of London, Merchant,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved pivot castor with bearing at the top of the
pivot and having an improved socket to fit over the pivot so constructed as to keep
the same in position with an improved plate attached to the socket.
In carrying out my invention where a ball bearing is employed I indent the
socket from the outside to form a projection inside to prevent the ball rolling out
when the pivot is withdrawn.
My improved socket is made by stamping in a press so that the top is flat and
the sides parallel the socket being then indented to form a projection on the inside,
which fits into a corresponding groove or channel around the pivot.
The plate is provided with a hole in the centre of a suitable size to fit round the
bottom part of the socket which is passed through the hole and is then by means
of a press or the like turned up to form a rim or flange which clips the plate and
holds the same firmly attached to the bottom of the socket.
It will be obvious that in place of a ball bearing in the tube I can employ a
conical-shaped bearing.

I, WILLIAM TIMMINS, of 10, Soho Square, in the county of London, Merchant,
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 furniture castors and comprises the improvements herein-
after described.
A castor made according to my invention has a long pivot or stem which fits
into and works within a socket stamped out of sheet metal and having a metal
cono bearing at the top for the pivot.
.
I indent the socket from the outside to form a projection inside to prevent the
bearing falling out when the pivot is withdrawn.
The socket is provided with a tubular portion and a plate or flange for fixing it
[Price 8d.]

page_text: to the furniture, the said tubular portion having a flat end, and the plate is pro-
vided with a hole in the centre of a suitable size to fit round the bottom part of the
tubular portion which is passed through the hole and is then by means of a press
or tho like turned up to form a rim or flange which clips the plate and holds the
same firmly attached to the bottom of the socket.
The pivot of the castor is formed with a circumferential groove or channel into
which after the said pivot has been placed in the socket a projection formed upon
the latter enters to prevent the pivot and the socket from becoming separated.
To enable my invention to be fully understood I will describe the same by refer-
ence to the accompanying drawing, in which:-
Figure 1 is a sectional elevation of a castor constructed according to my
invention:
Figure 2 is a vertical section of the socket portion of the castor:
Figure 3 is a view of the lower end of the same:
Figuro 4 is a vertical section of the plate of the castor; and,
Figure 5 is a plan of the said plate :
Figure 6 is a vertical section illustrating a slight modification :
Figure 7 is a section on the line 7-7 Figure 6:
Figures 8 and 9 are respectively an elovation and a longitudinal sectional
elevation illustrating another modification.
Similar letters of reference indicate corresponding parts in the several figures.
a is the castor wheel the frame or bracket & carrying which has fixed to it the
stem which forms the pivot of the castor.
d is the socket which is applied to the furniture in a manner which will be
readily understood by reference to Figure 1 and which serves to receive the said
stem in such a manner that the latter is free to turn therein. The tubular
portion of the socket, which is shewn detached in Figures 2 and 3 and which is
drawn or stamped out of sheet metal as herein before stated, has its upper or innor
ond made flat whilst its lower end is provided with a series of projections g, I
which form a collar or abutment. is the plate portion of the socket which is
also stamped out of sheet metal and provided with a central aperture which fits
on to the tubular portion f, the said plate being held against the abutments g, g
and fixed by expanding or rivetting the lower end of the said tubular portion e in
a manner which will be readily understood by reference to Figure 1.
i is the metal cone bearing for the pivot of the castor which bears against the
upper closed end of the tube e and is the indentation which is made in the tubular
portion from the outside, after the metal come bearing has been placed in position,
for preventing the said cone from falling out if the pivot pin is removed.
is a groove formed in the pivot pin or stem e and m is an indentation made in
the tube e from the outer side and serving to prevent the pin and the socket from
being separated. Instead of making an indentation m I sometimes form the
tubular portione of the socket with a tongue n as shewn in Figures 6 and 7, which
tongue enters the groove 1. As shown in Figures 6 and 7 this tongue is formed
circumferentially in the tubular portion e of the socket; if desired, however, it
may be formed longitudinally in the same as shown in Figures 8 and 9. In the
modification shown in those last two figures the groove or channel is made wider
than in the other cases and the free end of the spring tongue is slightly curved as
clearly shewn in Figure 9 so that if desired the pivot pin can be pulled out of the
socket.
J.
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. A furniture castor the pivot of which is arranged in a socket formed of two
stamped portions united together, substantially as described.
2. In a furniture castor wherein a pivot pin works in a socket as herein before
described and wherein a metal cone bearing is arranged between the end of the

page_text: pivot and the socket, forming in the said socket indentations to provent the parts
from becoming separated, substantially as described.
3. In a furnituro castor wherein a pivot pin works in a socket of the kind heroin-
before described, the arrangement of a tongue in the socket adapted to enter a
groove in the pivot pin, substantially as described.
4. The manufacture and use of furniture castors, substantially as hereinbeforo
described and illustrated in tho accompanying drawing.
