Improvements, in the Manufacture of the Sockets of Socket
Furniture Castors.
I
We, WILLIAM BENSON, Manager of William Benson and Company Limited, of
Aston Road, Birmingham, in the County of Warwick, and ALFRED BUTLER of
Poplar Terrace, Upper Thomas Street, Aston, Birmingham aforesaid, Tool Maker,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in the manufacture of the sockets of socket
furniture castors from sheet metal.
In carrying out one form of our invention, we take a thin sheet metal blank
preferably cut out from mild steel, and fashion the same into a shallow cup by
dies and pressure. Or the cutting out of the blank and the shallow cupping of the
same may be performed at one operation and by a. single pair of tools. Then, by
a further process of raising, the said cup is deepened and the walls of the same
conoidally shaped, so as to form a cup with tapering sides and of a depth sufficient
to forin the socket of a castor.
This said further process may be conducted partly by press tools and partly by
drawing through.
The middle of the hottom of the socket is then pierced, and through this piercing
and the socket of the horn the peg of the castor, takes.
If the boundary edge of the open mouth (which may be straight or flared)
requires a beaded or rolled edge, then by means of spinning or edging tools, the
thickened or rolled edge is produced.
If the edge of the open mouth of the socket should require to be furnished with
a turned down collar with a plain or scolloped edge, or with a turn back flange
slightly inclining downwards and standing away from the walls of the socket alike
unto a frill, then the cup is made deeper than the actual depth required to form
the socket and the metal of the boundary edge of the cup, for a short distance
below the top, is turned first outwardly and then downwardly to any desired angle,
and if the edge requires to be scolloped then when the metal of the collar is pre-
ferably in a plane at right angles to the cup, a scollop cutting-out tool ornaments
or fashions the edge.
This said steel socket may be further embellished

Furniture Castors.
We, WILLIAM BENSON, Manager of William Benson and Company Limited,.
of Aston Road, Birmingham in the County of Warwick, and ALFRED BUTLER, of
Poplar Terrace, Upper Thomas Street, Aston, Birmingham aforesaid, Tool Maker,
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:-
Our invention relates to improvements in the manufacture of the sockets of sheet
metal socket furniture castors.
In carrying out one form of our invention, we take a thin sheet metal blank,
preferably cut out from mild steel, and fashion the same into a shallow cup by dies
and pressure or by a drop stamp. Or the cutting out of the blank and the shallow
cupping of the same may be performed at one operation and by a single pair of
tools. Then, by a further process of raising, the said cup is deepened and the
walls of the same conoidally shaped, so as to form a cup with tapering sides and of
a depth sufficient to form the socket of a castor.
This said further process may be conducted partly by press tools and partly by
drawing through.
The middle of the bottom of the socket is then pierced, and through this piercing
and the socket of the horn the peg of the castor, takes.
Figure 1 of the accompanying drawings represents, in side elevation, a furniture
castor bowl made from thin sheet steel according to our improvements.
In carrying out the manufacture of the said bowl or socket a disc of thin sheet
steel, shown in plan and elevation in Figure 2, and by press tools or by a pair of
tools in a stamp, we raise the said blank into a cup figure with a flared mouth,
represented in section in Figure 3 and in plan in Figure 4. Then by further drop
stamping process or by press tools, the cup blank Figure 3 is further deepened and
the walls of 'the same graduated, whilst the lip of the mouth is brought further
over, as represented in Figure 5.
By the next process the said blank Figure 5, is shaped into the socket figure
represented in Figure 6. We next take the said roughly formed blank Figure 7,
and clip the edges of the same in a press, and the bottom a², of the body part a, is
pierced with a peg hole a', whilst the sides are pierced with screw holes a', thus
producing a finished socket as represented in section in Figure 7 and in plan in
Figure 8.
The said socket may be embellished by being cased with thin sheet brass,
aluminium or other metal. Such a cased socket is represented in elevation in
Figure 9, and in section in Figure 10.
In making such a sheet-brass-cased socket, we take a steel socket Figure 7 and
then case the saine with a thin brass cup, with a flared or open mouth, as represented
in Figure 11. The screw holes in the sides of the socket and also the peg piercing
in the bottom may be formed either before the component parts are put together,
or when they are together.
If the boundary edge of the open month (which may be straight or flared) of an
uncased socket requires a beaded or rolled edge, then by means of spinning or
edging tools, the thickened or rolled edge is produced, as represented in Figure 12.
Thus, a cupped blank with an enlarged mouth, as shown in Figure 13, is first
fashioned by dies and pressure, or by stamps, and the top edge a is rolled over
inwards into a beading a, although the said beaded edge may be made from a blank
Figure 6, but with the flange a', made broader.

page_text: If the edge of the open mouth of the socket should require to be furnished with
a turned down collar with a scolloped edge, as in Figure 14 or with a turn back
flange slightly inclining downwards and standing away from the walls of the socket
alike unto a frill, as represented in Figure 15 then the flange of the cup is made
broad, as represented in section in Figure 16, and in case the flange or collar
requires to be scoiloped, then, when the metal to form the collar is preferably in a
plane at right angles to the cup, (as represented in Figure 14) a scollop cutting-out
tool ornaments or fashions the edge.
The horn of the castor may be of the usual construction, or may be made of sheet
metal and fitted to the socket by the usual rivetted bearing peg, whilst the usual
bowl or runner is fitted between the branches of the horn.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. Making castor sockets from sheet steel by the process or processes and in
the way substantially as described and set forth in Figures 1 to 8.
Secondly. Making cased castor sockets from a thin sheet steel lining of the one
part and an outside thin metal casing of the other, with the said components con-
nected together by the process or processes and in the way substantially as
described and set forth in Figures 9 and 10.
Thirdly. Making castor sockets with plain, scolloped or beaded collars or frills
from sheet steel by the process or processes and in the way substantially as described.
and set forth in Figures 12 to 16.
