Improvements in the Manufacture of Stamped Metallic Rings for
the Ornamentation of Bedsteads and other similar purposes.
I ALFRED HEATH, of Cobden Works, 116 Leopold Street, in the City of
Birmingham, Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention relates primarily to improvements in the manufacture of stamped
metallic rings used in the construction and ornamentation of bedsteads, but which
may also be used for various other purposes such as cornice rings &c.
At present such rings are made by the casting process, or in some cases, similar
rings are made by the stamping or spinning processes, but in such latter cases they
are hollow open at their centre, that is, they do not thereat resemble a solid cast
ring, and in other cases they are made by pieces of tube, bent into the circular form
and then soldered.
In either of these methods the variety of patterns produced are necessarily
limited, are troublesome to make and consequently more costly than those made
under my invention.
This my said invention consists in making the said rings by stamping an "inner"

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Stamped Metallic Rings for
the Ornamentation of Bedsteads and other similar purposes.
I ALFRED HEATH, of Cobden Works, 116 Leopold Street, in the City of
Birmingham, Manufacturer, 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 primarily to improvements in the manufacture of stamped
metallic rings, used in the construction and ornamentation of bedsteads, but which
may also be used for various other purposes such as cornice rings &c.
At present such rings are made by the casting process, or in some cases, similar
rings are made by the stamping or spinning processes, but in such latter cases they
are hollow open at their centre, that is, they do not thereat resemble a solid cast
ring, and in other cases they are made by pieces of tube, bent into the circular
form and then soldered.
In either of these methods, the variety of patterns produced are necessarily

page_text: limited, are troublesome to make and consequently more costly than those made
under my invention.
"
This my said invention consists in making the said rings by stamping an "inner
"
"outer
part, forming the one side and inner or central portion, and an
part,
forming the external portion and the other side, and then securing these two parts
together at such joints (one on either side) by the closing or rolling over process.
The precise sectional form of these rings may be varied to suit taste or design,
and near their junctions one with the other, ** set backs " or recesses may be spun
therein to receive and support the consociate part, supporting and strengthening
such parts where the closing over takes place.
Any desired ornamental patterns, capable of being produced by the tools, may
be made in the parts before being united together.
In order to more fully explain how this my invention may be carried out, I have
appended hereunto an illustrative sheet of drawings, upon which are figures and
numbers of reference, similar numbers referring throughout the several views to the
same thing or part, and in which :-
Figs. 1, 2 & 3, shew the stages or processes by which the one part of the ring is
generally made.
Figs. 4 to 7, inclusive shew the stages or processes by which the other part of
the ring is made.
Fig. 8, shows in section the two parts thus formed, as when put together.
Fig. 9, is a plan of the complete ring.
Figs. 10 to 15 inclusive show the various stages or processes of producing a
modified form of this my invention.
I take a circular blank of metal and by means of a top and bottom tool in a
press in the well known manner of stamping or pressing or drawing machines, press
it into the shape shown in section in Fig. 1. The part at 1, may be variously
shaped according to the design or ornamentation desired, and may be together with
such ornamentation made in this or a subsequent operation. The central portion
is now cut out leaving the hole as seen at 2, Fig. 2. An all round recess is now
spun in the side at 3, in the ordinary way; the recess 4, being similarly put in to
harmonize the design.
I now take another blank of metal, and in a similar manner press or draw it into
the shape shown in Fig. 4. The hole 5, as seen in Fig. 5, is now cut out, and the
metal edge or rim at 6, is further stamped as seen in Fig. 6. The all round recess 7,
is now spun and a similar recess 8, is also made for design sake, both as seen in
Fig. 7.
These two parts are now placed together as shown in Fig. 8, when they are fixed
in a lathe chuck or similar contrivance, and the edges 9 and 10, are spun or closed
over, thus firmly securing the two parts together forming the complete ring as seen
in Fig. 9.
In Figs. 10 to 15, I have shown a modification in shape of this my invention, in
which the blank is first drawn into the shape shown in Fig. 10. The uneven edge
at 11, is then clipped and the central hole 5, is cut out as before. The annular
grooves or recesses 3", 4", 7" & 8ª, are now spun in as before described upon the
internal and external sides. A second part 12, as seen in Fig, 13, is now made by
first cutting out a blank and then submitting it to press tools, in the ordinary
manner. This piece 12, is now dropped in the open side of the first part, and rests
as before firmly upon the all round support formed by the recesses 3ª, and 7ª, and
the edge 9 and 10" rolled, spun or turned over as seen in Fig. 14, when the two
parts are thus firmly secured and the ring completed as also seen in plan in
Fig. 15.
The connecting joints of such two parts may be further secured by soldering if
desired, but usually it is not required.
I wish it to be understood that I do not claim the process or processes of stamping
or of spinning & c. as herein described, as they are well known operations, but :-

page_text: Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The making of metallic rings for bedsteads, cornice poles and other similar
purposes, of two parts constructed and secured in the manner herein described and
illustrated upon the drawings.
Dated this 24th day of November 1892.
