Improvements in the Construction of Casters.

I EDWIN MOORE of Priory Works, Aston, near Birmingham, in the county of
Warwick, Brassfounder, do hereby declare the nature of this invention to be as
follows :-
"
This invention relates to the construction of parts of castors for furniture and other
purposes, known as the sockets, that is, the part by which the "horns
or wheel
bracket is connected to the said furniture &c., and consists in the covering of such
sockets by sheet metal, in the manner following or similar thereto.
The body or "block" socket, that is, that which gives strength to the structure, is
made of inferior metal, generally of cast iron, and is made more or less ornamental,
and then covered upon the outside, with a thin covering of sheet metal.
This has been already done in cases where the design or shape of the casting or body
has been sufficiently plain to allow of the said body being covered with one piece of
metal, but in this my invention, I make such mounts or covers of two or more pieces of
metal, and close, press, or otherwise mount them upon the said body.
This enables me to make the said castings, or block sockets, of almost any desirable
design or figure, such as having ornamental frills, flanges, beads, recesses &c. upon
their exterior surfaces. At the seams or joints where such two or more parts would
come together, I should overlap, fold, braze, solder or otherwise make such joints so as
to be hidden as much as possible.

I EDWIN MOORE of Priory Works, Aston near Birmingham in the county of
Warwick Brassfounder 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:-

This invention relates to the construction of parts of casters for furniture and other
purposes, known as the sockets, that is the part by which the "horns or wheel
bracket is connected to the said furniture &c.; and consists in the covering of such
sockets by sheet metal, in the following manner, or similar thereto.
The body or "block"socket, that is, that which gives strength to the structure, is
made of inferior metal, generally of cast iron, and is made more or less ornamental, and
then covered upon the outside, with a thin covering of sheet metal.
This has been already done in cases where the design or shape of the casting or body
has been sufficiently plain to allow of the said body being covered with one piece of
metal, but in this my invention, I make such mounts or covers of two or more pieces
of metal, and close, press, or otherwise mount them upon the same body.
This enables me to make the said castings or block sockets of almost any desirable
design or figure, such as having ornamental frills, flanges, beads, recesses &c. upon
their exterior surfaces. At the seams or joints where such two or more parts would
come together, I should overlap, fold, braze, solder, or otherwise make such joints so as
to be hidden as much as possible.
I will now proceed to describe more particularly this my invention, and the manner
in which it is to be performed, by the aid of the accompanying sheet of drawings,
which have figures and letters of reference thereon.
Fig. 1, is a sectional elevation, and Fig. 2, a plan of a cast iron socket for caster,
having a frill or flange a, which is cast more or less ornamental in shape, upon the
said socket b.
The covering of the socket apart from the frill a, may be done in the ordinary
manner, as at present in use, and does not form part of this my invention, but in order
to cover the "frill" or flange in addition to the socket I proceed as follows:-I cut out
a blank similar to Figs. 3 & 4, of suitable diameter and thickness; I then press or
stamp this blank by suitable punches and dies, into the shape shewn by Figs. 5 & 6.
I then further with suitable punches and dies, press or stamp it into the shape shewn in
Figs. 7&8, having now a similar shape produced thereon to correspond to the frill
upon the cast iron socket.
I next clip or shear off the surplus metal of the edges c, and cut out the surplus
metal of the centre d, Figs. 7 & 8, thus producing the shape shewn in Fig. 9.
The necessary, annealing, pickling, cleaning, burnishing &c., usual in this class of
manufacture would be resorted to as required.

page_text: The frill" mount e, Fig. 9, would now be ready to be fixed upon the cast iron frilla,
when the edges f, of the said imount e, would be turned over by pressing, stamping or
spinning on to the mount g, covering the lower part of the socket b, thus firmly fixing
the mount e & g, in their respective places, and completely covering the cast iron frill,
as well as the socket, upon their outside.
The design, shape, or form, of the frill or flange, may be varied in modification of the
form shewn, and be covered in a similar manner as already described, as for instance in
the form shown in Fig. 11, where the rim may be ornamented with ribs, or other design
susceptible of being covered similarly as described.
Or, for instance, the frill may have beads, recesses or other formations which would
be difficult, or impossible to cover with one piece of metal, but may be accomplished
according to my invention.
Fig. 10 shews this my metal covered cast iron frilled socket, as it may be applied to
a completely manufactured caster.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The improvements in the manufacture of metal covered caster sockets, substantially
as herein described and illustrated, that is to say; the covering with two or more pieces
of sheet metal, of the combined cast iron sockets and ornamental "frills" or flanges, as
and for the purposes specified.
