I ALFORD GORDON of 77 Dearman Road, Camp Hill, Birmingham, in the county
of Warwick Brassfounder do hereby declare the nature of this invention to be as
follows:-
This invention relates to the ornamentation of metallic knobs and the method of
producing such ornamentation in their manufacture.
In the ordinary manufacture of stamped metallic knobs, such knobs are made of
two parts, the one part consisting of the "neck," and the other of the "shell" which
is formed out of a blank into a cup shape, and then turned over and closed into a nick
or groove formed in the said neck to receive it.
The object of this my invention is to produce an ornamentation or figured work
upon the exterior surface of this latter part, that is upon the surface of the shell.
In carrying out my invention I produce the desired ornamental figuring upon the
metal in its early stage of manufacture, either by rolling or stamping, for instance in
the former I may pass the metal, out of which the shells are subsequently to be made,
through rolls, together with a steel plate, upon the face of which is engraved or
otherwise formed the counter impression or impressions 1 wish to be reproduced upon
the metal. It will thus be seen that one side of a piece of metal thus prepared would
be plain, while upon the other side would be impressed the desired ornamentation.
Blanks of the necessary size to form the shells would be then cut out of the strip, and
the manufacture proceeded with similar as in the usual manner. Instead of forming
the impression of the ornamentation upon the metal by rolling, I may first cut out the
necessary plain blank, and then place it in an engraved or otherwise ornamented die,
and by stamping or pressing produce the impression upon the blank, or, the die
may be plain, and the marking impression be formed upon the punch. The blank
would be then operated upon in the ordinary course of manufacture, and after being
formed into the shell," would be closed upon the neck, and the knob completed.

page_text: The producing of the pattern or ornamental figure upon one side of the metal only
(leaving the other side plain) enables me to make the "shells" therefrom without
any, or at any rate with but a small amount of disfigurement, and so to produce a
knob, the shell part of which may be completely covered with ornamentation produced
by rolling or stamping; so that not only would such ornamentation be produced upon
the front part of the shell and on up to the largest part of its diameter but also again
on down the side to its junction with the neck. The amount of the surface of the
shell so ornamented would however be a matter of choice and design.
•
This my invention may be applied to the manufacture of all kinds of metallic knobs
where the shells are made out of sheet metal, such as, door, shutter, latch, drawer, &
bedstead knobs &c.

I ALFORD GORDON of 77 Dearman Road, Camp Hill, 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 ornamentation of metallic knobs, and the method of
producing such ornamentation in their manufacture. In the ordinary manufacture
of stamped metallic knobs, such knobs are made of two parts, the one part consisting
of the "neck," and the other of the "shell" which is formed out of a blank into a cup
shape, and then turned over and closed into a nick or groove formed in the said neck
to receive it.
The object of this my invention is to produce an ornamentation or pattern upon the
exterior surface of the shell of the knob, at the same time preserving the inner surface
quito plain.
In carrying out my invention I produce the ornamental pattern upon the metal in
its early stage of manufacture, either by rolling or other pressure; for instance, in the
former I may pass the metal, from which the shells are subsequently to be made,
through rolls, together with a steel plate upon the face of which is engraved or
otherwise formed the counter impression or impressions I wish to bo reproduced upon
the metal. It will thus be seen that one side of a piece of metal thus prepared would
be plain, while upon the other side would be impressed the desired ornamentation.
Blanks of the necessary size to form the shells would then be cut out of the strip, und
their manufacture proceeded with similar as in the usual manner.
Instead of forming the impression upon the metal by rolling, I may if desired place
the metal in an engraved or otherwise ornamented die, and with a plain surfaced
punch, by pressure produce the impression upon the one side of the blank, or, the die
may be plain and the marking impression be formed upon the punch. The blank
would then be further operated upon in the ordinary method of manufacture, and
after being formed into the shell, would be closed upon the neck, and the knob
completed.
The producing of the pattern or ornamental figure upon one side of the metal only,
leaving the other side plain, enables me to make the "shells" therefrom without any,
or at any rate with but a very small amount of disfigurement of the pattern. This
liability to damage the said pattern is very much, and in some cases entirely removed,
by the selection of a pattern suitable for such purposes, as will be further explained.
I will now proceed to further and more clearly describe this my invention having
reference to the accompanying illustrative sheet of drawings, upon which are figures
and letters of reference.
Fig. 1, shews a plan of a piece of metal out of which the shell of the knob is to bo
made, after the ornamentation has been produced upon its surface.
Fig. 2, is a view of a steel plate, having engraved upon its surface a pattern,
which is to produce its counterpart or design upon the plate Fig. 1.
Fig. 3, is a sectional view of rolls, through which the steel plate, and the metal
plate, inay be passed, under pressure, in order to force the metal of the latter into the

page_text: pattern of the former, and thus reproducing the counterpart pattern of the steel plate
upon the said metal plate.
Fig. 4 is a view of such metal plate after being impressed.
Fig. 5 shews circular blank, cut from Fig. 4, ready for cupping &c. to form the
shell of the knob.
Fig. 6 shews the circular blank formed into a cup shape, preparatory to its being
turned over and closed into the neck to form the complete knob.
Figs. 7&8 are views of completed knobs made after the manner of this my
invention.
In producing these designs or patterns I prefer generally to adopt the rolling
process as described and illustrated, but as I have already intimated, similar results
may be obtained by bringing sufficient pressure to bear upon the engraved steel plate
or die, by other arrangements of mechanism.
By these means I may produce metallic knobs having an ornamental surface,
completely covering the shell, but in doing so, I find it an advantage to select such
patterns, which have their lines &c., somewhat of a radiating form at or near such
part indicated at a Fig. 6, so that the drawing of the metal at such part does not
disfigure such lines, as it would, were such lines running circularwise.
Generally however I find the best results to follow, both in the manufacture and
also in pleasing effect, to modify such patterns, as that oither to limit the pattern to
the covering of more or less of the front of the knob, as for instance such pattern as
would be included within the dotted lines b-c, Fig. 4, and which would produce a
knob similar as shown in Fig. 7, or otherwise to arrange for a band of plain metal d―e
Figs. 4 & 5, where the drawing of the metal takes place, and further forming an
ornamental band f, g, Figs. 4 & 5 which would appear upon the closed over part, near
its junction with the neck of the knob, as shown in Fig. 8.
•
I am aware that the ornamenting of metallic knobs has already been adopted by the
ordinary process of stamping, that is, where the impression upon the metal is not only
produced upon one side, but upon both sides, by reason of the metal being indented
to produce such designs; but such method of ornamentation is not capable of such
artistic finish and effect, as is my invention; and unless producod upon the shell, after
it has been formed into such shell shape, would be very liable to stretch such orna-
mentation altogether out of shape, while in my invention, after the ornamental design
has been produced upon the blank, the said blank is, to all intents and purposes for
the subsequent operations, as a plain, solid, flat blank, which may be treated in the
ordinary manner.
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 :
1st. The improvements in the ornamenting of metallic knobs, as herein described
and illustrated upon the drawings Fig. 1 to 8 inclusive, that is to say, the manu-
facture of ornamented metallic knobs, having their shells formed out of blanks which
have an ornamental pattern, produced upon their one side only, by rolling or other
pressure.
2nd. The ornamenting of metallic knobs by producing an ornamental or artistic
design upon the one side of the shell only, by pressure, during their manufacture.
