We JAMES EDWARD BEAVER, and WILLIAM GOODMAN WARD trading as Beaver
and Ward of 30 Augusta Street Birmingham in the County of Warwick Stampers
and Piercers, do hereby declare the nature of our Invention for IMPROVEMENTS. IN
THE MANUFACTURE OF RIMS OR RINGS APPLICABLE TO FURNITURE CASTORS, AND
OTHER ANALOGOUS PURPOSES," to be as follows:-
Our Invention consists of the improvements herein after described in the
manufacture of rims or rings, as applied to castors, and used for articles of
furniture, and also to the handles of perambulators, and such like purposes.
Hitherto these rims or rings have been produced by casting, which are heavy,
and costly in metal, and then require turning and never make so good a class of
work as when made. from rolled or sheet metal.
We will describe our Invention thus From sheet or rolled metal we cut a
circular form of a required size and by means of dies we dish the same, and then
pierce or cut out the bottom. A ring is thus formed, with press tools specially
provided to meet the exterior edges both top and bottom of this ring and pressure
being applied causes the outer surface of the ring to bulge or swell and forms a
bead with a hollow in the interior; another circular form is pierced or cut out,
and rose up to a cone shape, this one is of such a size as to pass into the first
named, and pressure being applied to the surface flattens the same forcing the edge
into the hollow of the bead and is perfectly secure.
Or we may in some cases stamp or dish two parts each having little more than
half a bead and one somewhat smaller than the other, the bottoms are both cut out
of these; and a flat ring being pierced is placed in the larger one; the smaller one
is then arranged upon the same and finally rolled or closed over thus forming
a bead.

We, JAMES EDWARD BEAVER, and WILLIAM GOODMAN WARD, trading as
Beaver and Ward" of 30 Augusta Street, Birmingham, in the County of
Warwick, Stampers and Piercers, do hereby declare the nature of said 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 consists of the improvements herein after described in the
manufacture of rims or rings, as applied to castors, and used for articles of
furniture, and also to the handles of perambulators, and such like purposes.
Hitherto these rims or rings have been produced by casting, which are heavy,
and costly in metal, and then require turning and never make so good a class of
work as when made from rolled or sheet metal.
We will describe our Invention thus.-From sheet or rolled metal we cut a
circular form of a required size and by means of dies we dish the same and then
pierce or cut out the bottom, a ring is thus formed, with press tools specially
provided to meet the exterior edges both top and bottom of this ring: and pressure
being applied causes the outer surface of the ring to bulge or swell and forms a
bead with a hollow in the interior; another circular form is pierced or cut out, and
rose up to a cone shape, this one is of such a size as to pass into the first named,
and pressure being applied to the surface flattens the same forcing the edge into
the hollow of the bead and is perfectly secure.
Or we may in some cases stamp or dish two parts each having little more than
half a bead and are somewhat smaller than the other the bottoms are both cut out
of these; and a flat ring being pierced is placed in the larger one, the smaller one
is then arranged upon the same and finally rolled or closed over thus forming
a bead,
And in order that this our said Invention may be more thoroughly understood,
we will now proceed to describe the same by the aid of the accompanying
drawings, similar letters of reference denote similar parts in each figure where
they occur.
Fig. 1, shows section and plan of "blank" of sheet metal, for forming the
outer case.
Fig. 2, shows section and plan of the same piece pressed into a dished form.
Fig. 3, shows section and plan of the same piece (that is outer casing having the
bulge given to its sides and the bottom punched out.
Fig. 4, shows section and plan of "blank" of sheet metal for inner piece.
Fig. 5, shows elevation and plan of same, when pressed into such a shape as to
slip inside the outer case Fig. 3.
Fig. 6 shows section and plan of the completed rim or ring.
Fig. 7, is an elevation and
Fig. 8, is a plan of rim or ring with beaded edge.

flattened and the edge forced into the hollow c, Fig. 6.-In Figs. 7 and 8, e is the
upper part and f, the lower part with bottom cut out at g, the dotted line h
indicating the edge of e, fitted into f, after the flat ring i has been inserted and the
edge rolled or closed over at j.
We do not confine ourselves to the precise details herein given and set forth and
shewn on the accompanying drawings but that we hold ourselves at liberty to alter
or modify the same without departing essentially from the principle of our said
Invention.
.
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
.
The construction, combination or arrangement of parts as herein before described
and illustrated the whole forming "Improvements in the manufacture of rims or
rings applicable to furniture castors and other analogous purposes."
