PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Sheet Metal Terminal
Ornaments, Knobs, and the like.
I, THOMAS SMITH of Lombard Street, in the City of Birmingham, Manager of
Works, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of terminal ornaments, knobs and the
like from a single blank of sheet metal.
In carrying out the manufacture of a terminal knob or ornament according to
my invention, I take a sheet metal blank having sufficient metal to form the head,
neck and other parts of the article to be made. I then first cup the blank by dies
and pressure, spinning, drawing-through or other means and form the head, neck
and other parts of the same all integral by excentric rolling, spinning or other
means well known in the arts for the fashioning of hollow sheet metal articles.
Then by a series of processes the mouth end is fashioned into a neck of the desired
diameter and figure, and with a shoulder coming at the bottom of the throat to
form a stop against which the inner end of the pummel, as hereinafter described,
abuts.
Now the diameter of the inside walls of the neck is the same as the outside
diameter of the pummel, which is smaller at the inner end than at the other end
or base, so that the said pummel shall socket the neck and be there affixed by
turning the edge of the metal at the entrance to the throat over the end of the
pummel.
I propose that the pummel should in every case be of the inside figure of the
neck, and that when the articles to be made are to be patterned or ornamented,
then the patterning may be in common upon the pummel and the neck.
The shaping and ornamenting of the exterior surface may be conducted by one
or more sets of tools at one or more operations.
The pummel may be of wrought or cast metal, either malleable or otherwise.

I, THOMAS SMITH of Lombard Street, in the City of Birmingham, Manager of
Works, 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 of terminal ornaments, knobs and the
like from a single blank of sheet metal.
In carrying out the manufacture of a terminal knob or ornament according to
Do31

page_text: my invention, I take a sheet metal blank having sufficient metal to form the head,
neck and other parts of the article to be made and first cup the blank by dies and
pressure, spinning, drawing-through or other means and then form the head, neck
and other parts of the same all integral by excentric rolling, spinning or other
means well known in the arts for the fashioning of hollow sheet metal articles.
Then by a series of processes the mouth end is fashioned into a neck of the desired
diameter and figure, having a set-off at its junction with the head or body and with
a shoulder coming at the entrance to the throat to form a stop against which the
inner end of an inserted pummel which forms a foundation or internal support upon
the neck is formed, abuts on socketting into the neck.
Now the diameter of the inside walls of the neck is the same as the outside
diameter of the pummel, which is smaller at the inner end than at the other end
or base, so that the said pummel shall socket into the neck and be there affixed
both by turning the edge of the metal at the entrance to the throat over the end
of the pummel and by gathering the metal of the neck around the narrow part of
the pummel.
I propose that the pummel should in every case be of the inside figure which
the neck is to acquire, and that when the articles to be made are to be patterned
or ornamented, then the patterning may be in common upon the pummel and the
neck.
The shaping and ornamenting of the exterior surface may be conducted by one
or more sets of tools at one or more operations.
The pummel may be of wrought or cast metal, either malleable or otherwise,
and may be slightly serrated, ribbed or otherwise roughened upon its exterior
surface.
Figure 1 represents in vertical section a sheet metal vase, knob or terminal made
according to my invention from a single blank of sheet metal and fitted with a
pummel at the mouth entrance for receiving the screw of a bedstead.
Figure 2 is an underside plan of same.
Figure 3 represents the shell of the said knob separately.
Figure shows the said shell and the pummel socketting into the neck and
before the edges of the said shell are turned over the lower end of the pummel.
Figure 5 is an underside plan of Figure 3.
Figure 6 is a cross section of Figure 1 upon the dotted line a.
Figure 7 is an elevation, Figure 8 a vertical section, and Figure 9 an underside
plan of the pummel separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is a shell, having a neck a', and shoulder a², and a set-off a', at the junction of
the neck with the body, whilst b is a solid metal pummel, inside screwed at 6', and
socketting into the said neck, with the foot 6, coming against the shoulder a', of
the neck and being there secured by turning the metal at the edge a³, of the throat
of the neck over the lower end of the pummel, which is slightly serrated or
otherwise roughened at 6, for the purpose of preventing the pummel from rotating
within the neck of the knob.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Making terminal ornaments, knobs and the like from a single blank of
sheet metal, with the entrance to the neck of the same formed with a shoulder,
and with a set-off formed at the junction of the said neck with the body and
within which neck a solid metal pummel sockets, substantially as described and set
forth.
Secondly. Making terminal ornaments, knobs and the like from a single blank
of sheet metal, with the entrance to the neck of the same formed with a shoulder,
and within which neck a solid metal pummel sockets and is there secured either by

page_text: gathering the metal of the said neck around the narrow part of the pummel or
by both gathering in the metal of the said neck and turning the bottom edge of the
same over the lower end of the said pummel, substantially as described and set
forth.
