We GEORGE MOORE and ARTHUR LIONEL STAMPS, both of Priory Works, Aston,
in the County of Warwick Manufacturers do hereby declare the nature of this
invention to be as follows:-
This invention relates to the manufacture of parts connected with the sockets of
casters, and has for its object the covering of such parts with sheet metal.
It is customary to make such sockets of cast iron and then form a thin motal cup
(generally brass) into which the cast iron socket is passed and secured, thus having
the appearance of a solid brass socket. It is further desirable to ornament such
sockets by providing an ornamental frill or flange around them; but hitherto such
frills or ornaments have been made of solid metal. In this our invention however we
form such frills or ornaments upon the cast iron sockets and then further, by suitable
tools, we cover the said frills or ornaments with sheet metal in a similar manner to
the socket itself. Thus by these means we are enabled to produce a cast iron socket
having an ornamental frill, covered upon its external surface by sheet metal (brass
for instance) while at the same time having the appearance of a solid frilled or
ornamented brass socket.

page_text: We GEORGE MOORE and ARTHUR LIONEL STAMPS both of Priory Works, Aston in
the county of Warwick Manufacturers do hereby declare the nature of this invention
and in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement:—
This invention relates to the manufacture of parts connected with the sockets of
castors, and has for its object the covering of such parts with sheet metal.
It is customary to make such sockets of cast iron, and then form a thin metal cup
(generally brass) into which the cast iron socket passed and secured, thus having
the appearance of a solid brass socket. It is further desirable to ornament such
sockets, by providing an ornamental frill or flange around them, but hitherto such
frills or ornaments have been made of solid metal. In this our invention however we
form such frills or ornaments upon the cast iron sockets, and then further by suitable
tools, we cover the said frills or ornaments with sheet metal in a similar manner to
the socket itself. Thus by these means we are enabled to produce a cast iron socket
having an ornamental frill, covered upon its external surface by sheet metal (brass
for instance) while at the same time having the appearance of a solid frilled or
ornamented brass socket.
We will now proceed to describe more particularly this our 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, is 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.
In covering the combined socket and frill, we should proceed somewhat in the same
way as covering only the socket itself, that is, we should provide a thin metal cover
somewhat similar in shape to that shewn in Fig. 6, and, being not only provided
at c to cover the lower (ordinary) part of the cast iron socket, but enlarged at d, to
receive and cover the frill a. The method of producing this covering Fig. 6, would
be similar to the ordinary process or method, adopted for the production of similarly
shaped articles, out of sheet metal blanks Figs. 3 & 4, (Fig. 4 being an edge view
of Fig. 3).
We have shewn but one intermediate process or shape namely Fig. 5, but the
number of operations to produce the covering, would be according to the nature and
requirements of the particular socket to be covered.
Having produced in Fig. 6 the exact shape to receive the socket Fig. 1, the latter
is placed therein, and then by suitable tools in a press, or by spinning, or closing, the
metal is folded over similarly as shewn in Figs. 8 & 9.
It will now be observed that the metal covering at the edges of the frill e, Figs. 8

page_text: &9, is still left circular in form; this however we next proceed to conform in shape
to the "frill" or ornamental part of the said socket.
This may be done by placing the now covered socket in a press in a horizontal
position, and properly supporting the same, a top tool is brought down into each
hollow, one or more at a time, the said socket being turned round between each
operation, brings a new hollow or hollows central, to be operated upon, until the
whole of such hollows are thus shaped. Other methods of pressing the covering
metal into the figure or pattern of the frill, may however be adopted, such as two
or more tools acting simultaneously upon the hollows or other figures, to press the
metal to their shape.
These modifications of the tools and their application, is chiefly determined however
by the particulars of the design or shape of the frill to be covered.
From these latter remarks it will be understood that the pattern or shape of the
"frill" may be varied to suit taste.
Fig. 11, is an illustration of one form of frilled socket, covered according to our
invention, made up into a complete caster.
We are aware that cast iron sockets have been made with a plain beaded edge, and
that such beaded edges have been covered in conjunction with the socket similarly as
shewn in Fig. 12 & 13, Fig. 12 being a section and Fig. 13 a plan of such a covered
socket, and therefore we do not claim the covering of such plain beaded edges upon
cast iron sockets.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1st. The improvements in the manufacture of the metal covered sockets for casters,
substantially as herein described and illustrated upon the drawings, that is to say the
casting or forming upon cast iron sockets, that are to be covered by sheet metal, of
an ornamental frill or flange.
2nd. The improvements in the manufacture of the metal covered sockets for casters,
substantially as herein described and illustrated upon the drawings, that is to say.
The covering with one piece of sheet metal, of combined cast iron sockets, and
ornamental frills or flanges for casters.
