Improvements in the Manufacture of Bedstead and other
Metal Knobs.
1, GEORGE RATHERAM PAYNE, of Colwyn Villa, 30 Gladstone Road,
Sparkbrook, in the City of Birmingham, Manager, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the method or process of manufacturing metal knobs
for use upon bedsteads and for other purposes, which 1 employ for the purpose of
producing a strong and substantial knob capable of being screwed by its stem on
to any bedstead frame or other article.
In carrying my invention into effect I produce a knob with a stem or projecting
pin for bedstead ornamentation and constructional purposes in the following
manner I form a pin or screw stem of metal with a small shouldered bead at one
end, this head being preferably square so as to prevent rotation of the washer
which I place upon the end. Instead of forming a square end or head I sometimes
make the shape oval or of any form other than a true circle for the prevention of
movement. Beneath the head I prefer to form a projecting neck or collar to
serve as a seat or stop for the washer plate to rest against. This washer plate I
make from iron, steel or other suitable metal, and I make a central hole within it
to fit on to the head of the pin, so as to form when in position upon the pin a
body or inner support for the built up knob which I form about the pin. The
knob portion or globular or other shaped ornamental head which I form upon the
pin or stem screw I construct from two discs or separate semi-globular or other
shaped cups; these semi-cups being produced in any well known manner by
pressing or spinning up from sheet metal. The upper portion of the knob to be
thus formed I make with its extreme end portion of the correct shape desired to
suit the knob that is to be produced; while its lower or open end I make with a cup
like ring or recessed flange for the washer plate to fit within. The lower portion
of the knob I produce by pressing or forming in any well known manner a like
semi-cup or dished plate having a small flange like rim at its open end for entering
the recess or ring provided upon the upper portion of the knob, this flange fitting
on to the washer plate previously placed in position within the cup about the
stem.
I prefer to form the washer plate with its edges or rim serrated, grooved, or
with flats thereon, so that the metal of the cup recess may be pressed into the
grooves or made to take the peculiar shape of the washer and the whole made
capable of being turned round or screwed into any hole as one piece.
When I have formed the lower portion of the knob as a semi.cup, I make a
central hole within it to permit of the stem or screw pin passing freely through,
the flange or neck projection beneath the head of the pin preventing the pin from
going right through; or when no neck is formed upon the pin the enlarged head
or connected washer plate prevents this.
After having placed one cup within and upon the other, and having pressed the
pin and washer into position, I spin over, press over or otherwise close down the
cup like flange, to secure one portion of the knob to the other, and I preferably
mill or groove the outer edges of this beaded over flange so as to provide a
suitably roughened surface for manipulating the stem when screwed or otherwise.
Instead of milling the edges of this central manipulating portion of the knob I
sometimes form them with flats thereupon for the same manipulating purposes.

page_text: I make my improved combination knobs and pins of any desired form and I
vary the particular metals which I employ to suit any particular requirement.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Bedstead and other
Metal Knobs.
I, GEORGE RATHERAM PAYNE, of Colwyn Villa, 30 Gladstone Road,
Sparkbrook, in the City of Birmingham, Manager, 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 method or process of manufacturing metal knobs
for use upon bedsteads and for other purposes, which I employ for the purpose of
producing a strong and substantial knob capable of being screwed by its stem on
to any bedstead frame or other article.
Referring to the accompanying sheet of drawings
Figure 1 is an elevation of a pin prepared to carry out my invention.
Figure 2 shows plan and elevation of a washer to be riveted to the pin.
Figure 3 shows the two cups required to form my knob.
Figure 4 is a section showing my knob and pin when put together.
Figure 5 is an external elevation corresponding to Figure 4.
Figure 6 is an external elevation of a pin prepared in another way.
Figure 7 shows a pin riveted over a washer.

Figure 8 shows the pin as in Figure 7 with the lower cup in position.
In carrying my invention into effect I produce a knob with a stem or projecting
pin for bedstead ornamentation and constructional purposes in the following
manner I form a pin or screw stem of metal as at Figure 1 with a small
shouldered head b at one end, this head being preferably square as at b, so as to
prevent rotation of the washer c Figure 2 which I place upon the end. Instead
of forming a square end or head I sometimes make the shape oval or of any form
other than a true circle for the prevention of movement. Beneath the head I
prefer to form a projecting neck or collar as a to serve as a seat or stop for the
washer plate c to rest against. This washer plate c I make from iron, steel or
other suitable metal, and I make a central hole within it to fit on to the head of
the pin, so as to form when in position upon the pin a body or inner support for
the built up knob which I form about the pin. The knob portion or globular or
other shaped ornamental head which I form upon the pin or stem screw I construct
from two discs or separate semi-globular or other shaped cups such as are shown
at de Figure 3; these semi-globular cups being produced in any well known
manner by pressing or spinning up from sheet metal. The upper portion d of the
knob to be thus formed I make with its extreme end portion of the correct shape
desired to suit the knob that is to be produced; while its lower or open end I make
with a cup like ring or recessed flange g for the washer plate c to fit within. The
lower portion e, of the knob, I produce by pressing or forming in any well known
manner a like semi-globular or dished plate having a small flange like rim hat
its open end for entering the recess or ring g provided upon the upper portion d of
the knob, this flange fitting on to the washer plate c previously placed in position
within the cup about the stem.
I prefer to form the washer plate with its edges or rim serrated, grooved or with
flats as shown at Figure 2, thereon so that the metal of the cup recess g. may be
pressed into the grooves or made to take the peculiar shape of the washer and the
whole made capable of being turned round or screwed into any hole as one piece.

page_text: When I have formed the lower portion e of the knob as a semi-globular cup, I
make a central hole within it to permit of the stem or screw pin passing freely
through, the flange or neck projection a beneath the head of the pin preventing
the pin from going right through; or when no neck is formed upon the pin the
enlarged head e or connected washer plate prevents this.
After having placed one cup e within and upon the other, d, and having pressed
the pin and washer into position, I spin over, press over or otherwise close down
the cup like flange g to secure one portion of the knob to the other, and I
preferably mill or groove the outer edges of this beaded over flange f Figures 4
and 5 so produced so as to provide a suitably roughened surface for manipulating the
stem when screwed or otherwise. Instead of milling the edges of this central
manipulating portion of the knob I sometimes form them with flats thereupon for
the same manipulating purposes.
I make my improved combination knobs and pins of any desired form and I vary
the particular metals which I employ to suit any particular requirement.
Figures 1, 2 and 3 illustrate the separate portions of my knob and screw.
Figure 4 shows the parts assembled together, the washer c being riveted to the
square head and the said washer e placed in the groove, 9, (Figure 3) and the
said groove closed over to produce the beaded edge or flange f. The washer c
being firmly held within the completed knob.
Figure 5 shows an external elevation of the completed knob and pin.
Figure 6 shows a pin with a head c formed without riveting.
C
Figure 7 shows the riveted head and Figure 8 shows the lower cup e in position
ready for placing on the upper cup d.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what
I claim is.
1. A bedstead or other metal knob and pin built up in the manner hereinbefore
described and illustrated in the accompanying drawings.
2. A bedstead or other metal knob and pin in which the pin carries a head as a,
shoulder as b, washer as c, enclosed within a knob formed of cups as d and €, the
said cups being closed together to form a knob in such manner as to produce a
ridge or bead as when finished, the washer c being firmly held within the recess g,
substantially as herein before described and illustrated in the accompanying
drawings.
