Improvements in Castor Rings, Cornice Pole Rings, Rose Rings,
and other Rings and Annular Articles of like Manufacture.
We, FREDERICK MATCHETT and HARRY MATCHETT both of George Street'
Birmingham in the County of Warwick Manufacturers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the manufacture or production of castor rings or annuluses,
cornice pole rings, knob roses and other rings and annular articles of like manufacture,
which have usually been made solid or in one piece, by the process of casting, and
afterwards shaped and finished, by turning or by other well known processes.
The object of our said invention is to reduce the cost of manufacture of the said
articles, while retaining the same finish, efficiency and durability of those made by
the ordinary process of manufacture.
We will describe our invention in connection with what is usually termed a castor
ring, which consists of a broad annular collar, with an internal flange disposed near
one edge, and a swell or mound upon its outer circumference.
In carrying out our invention, we make the said ring of two parts; an inside body
part or base of cast iron, chilled cast iron, malleable cast iron, or other inferior metal;
and which said ring of cast metal is provided on its inner and outer peripheries with
the usual swells or flanges. A thin sheet metal ring or blank is then taken, of a little.
more than the breadth of the cast ring to be covered, and of an internal diameter of
about equal to the larger diameter of the said ring; then by a shaping process, the
thin sheet metal covering is enclosed upon the cast metal base, with the edges of the
said covering, gathered or tucked slightly over the inside edges.

page_text: The process of covering may be effected either by upper or lower dies, or by press
tools, which gather the sheet metal coating around the periphery, and over the edges
of the cast metal base.
Or the shaping may be effected by spinning or shaping in a lathe.
By making up rings as described, the process of manufacture is greatly simplified,
and their cost reduced.
Thus the ring as aforesaid, consists essentially of a cast iron, or cast metal base,
with an external coating of sheet brass.
The application of our invention to other articles of like manufacture, differs in no
essential respect from that already described.

page_text: and other Rings and Annular Articles of like Manufacture.
We, FREDERICK MATCHETT and HARRY MATCHETT both of George Street
Birmingham, in the County of Warwick, Manufacturers, 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 manufacture or production of castor rings or annuluses,
cornice pole rings, knob roses, and other rings and annular articles of like
manufacture, which have usually been made solid or in one piece, by the process of
casting, and afterwards shaped and finished, by turning or by other well known
processes.
The object of our said invention is to reduce the cost of manufacture of the said
articles, while retaining the same finish, efficiency, and durability of those made by
the ordinary process of manufacture.
We will describe our invention in connection with what is usually termed a castor
ring, which consists of a broad annular collar, with an internal flange disposed near
one edge, and a swell or mound upon its outer circumference.
In carrying out our invention, we make the said ring of two parts; an inside body
part or base of cast iron, chilled cast iron, malleable cast iron, or other inferior metal;
and which said ring of cast metal, is provided on its inner and outer peripheries, with
the usual swells or flanges. A thin sheet metal ring or blank is then taken, of a
little more than the breadth of the cast ring to be covered, and of an internal diameter
of about equal to the larger diameter of the said ring; then by a shaping process, the
thin sheet metal covering is enclosed upon the cast metal base, with the edges of the
said covering, gathered or tucked slightly over the inside edges.
The process of covering, may be effected either by upper or lower dies, or by press
tools, which gather the sheet metal covering around the periphery, and over the edges
of the cast metal base.
Or the shaping may be effected by spinning, or shaping in a lathe.
By making up rings as described, the process of manufacture is greatly simplified,
and their cost reduced.
Thus, the ring as aforesaid, consists essentially of a cast iron, or cast metal base,
with an external coating of sheet brass.
The application of our invention to other articles of like manufacture, differs in no
essential respect from that already described.
We will now proceed to describe with reference to the accompanying drawing, the
manner in which the same is to be performed.
Figure 1 represents in side elevation, figure 2 in transverse vertical section, and
figure 3 in plan, a furniture castor ring, made according to our invention.
Figure 4 is a transverse vertical section, and figure 5 is an inverted plan, of the

page_text: cast metal base, of the said ring, which is subsequently externally enclosed, as herein-
after described, by a thin sheet metal covering or shell, of superior metal.
The said body or base part, of the ring, is preferably made of malleable, or other
cast iron.
Figure 6 represents a side elevation, and figure 7 a plan of the outer covering or
shell, which is preferably made of brass, and spun or raised, by processes commonly
known.
Figure 8 represents a section of the cast body part, and the covering shell, together,
before the opposite or outside edges, are turned over upon the cast part.
In making a ring, as in figures 1, 2 and 3, we take a cast iron base, figures 4 and 5,
and introduce it into the shell, figures 6 and 7, then by means of shaping tools, we
close the sides of the said shell, upon the outside of the base, and with the outside
edges gathered over the top and bottom edges of the ring, as represented in the section,
at figure 2.
a is the cast metal body part, and 6 is the outer sheet metal covering.
Figure 9 represents a plan, and figure 10 a side elevation of a square-shaped castor
ring, constructed according to our invention.
Although we have only described and represented, that the cast metal base is
covered upon the outside, and exposed edges, with thin sheet brass, yet the inside may
if necessary, be covered cither by an independent shell, or by extending the edges of the
blank inwardly; and further, although we prefer to use a cast iron base, yet wrought
metal may be employed.
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.
First. A furniture castor ring, consisting of a cast, or wrought metal base,
covered or enclosed externally, or both externally and internally, by a thin sheet brass,
or other metal shell or covering, substantially as, and for the purpose as herein
described and set forth in figures 1 to 9.
Secondly. A ring or annulus, for various purposes, consisting of a cast, or wrought
metal base, covered with a sheet metal shell or casing, as herein described and set
forth.
