Improvements in the Manufacture of Knobs or Terminal
Ornaments for Metallic Bedsteads and Cots.
We, THEODORE HASLUCK and STEPHEN MARTIN, trading together as Martin
Hasluck & Co. of 249, New John Street West, Hockley, in the City of
Birmingham, Brass Bedstead Ornament Manufacturers, and WILLIAM DINGLEY,
of Jubilee Avenue, Lennox Street, in the City of Birmingham, aforesaid, Foreman
Burnisher, do hereby declare the nature of this invention to be as follows:-
This invention has reference to that kind of knob or terminal ornament for
metallic bedsteads and cots which consists essentially of two parts, namely a
spherical or almost spherical upper part (which is raised from a single sheet metal
blank and has a circular hole or mouth at its base) and a lower part or neck which
is secured to the hole or mouth of this upper spherical part and has a central screw
threaded hole for the attachment of the knob or terminal ornament to the screw on
the pillar of the bedstead or cot.
Heretofore it has been customary to make the said neck of cast metal which is
comparatively expensive.
According to this invention we employ what is known as a "rolled neck" that is
a neck which is raised and formed from sheet metal and we fix the rolled neck and
the upper spherical part together by an improved method as herein described
whereby it is impossible for the rolled neck and the upper spherical part to become
detached from each other or to work loose. This we effect by making an
outwardly projecting lip all round the said hole or mouth of the upper spherical
part, the extreme outer part of this lip is of larger diameter than the hole or mouth
so that there is a decided groove all round the outside of the lip where it connects
to the upper spherical part. This lip may be formed by suitable dies or tools
worked in a press or by other means.
The said lip is inserted in the open top of the "rolled" or other sheet metal neck
which latter is made of a size to fit tightly around the lip, and the neck is then
firmly secured to the spherical upper part by closing or beading the top edge of
the neck inwardly so as to engage tightly in the groove in the lip.
We also provide
a cast or other solid metal pommel in the base of the neck
around which the neck is closed or rolled this pommel having the screw threaded
hole for attachment of the knob or terminal ornament to the screw on the pillar
of the bedstead or cot. In order to effectually secure this pommel in the said
rolled or other sheet metal neck and prevent the pommel becoming loose we make
an annular or other groove or recess or grooves or recesses in the under surface
of the pommel into which the metal of the neck is closed or pressed whilst the
top of the pommel fits against an inner shoulder formed by reducing the diameter
of the neck at that part.

Improvements in the Manufacture of Knobs or Terminal
Ornaments for Metallic Bedsteads and Cots.
THEODORE HASLUCK and STEPHEN MARTIN, trading together as Martin,
Hasluck and Co. of 249, New John Street West, Hockley in the City of
Birmingham, Brass Bedstead Ornament Manufacturers and WILLIAM DINGLEY,
of Jubilee Avenue, Lennox Street in the City of Birmingham, aforesaid, Foreman
Burnisher 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 :-
Our invention has reference to that kind of knob or terminal ornament for
metallic bedsteads and cots, which consists essentially of two parts, namely a
spherical or almost spherical upper part (which is raised from a single sheet metal
blank and has a circular hole or mouth at its base) and a lower part or neck which
is secured to the hole or mouth of this upper spherical part, and has a central
screw-threaded hole for the attachment of the knob or terminal ornament to the
screw on the pillar of the bedstead or cot.
Heretofore it has been customary to make the said neck, of cast metal which is
comparatively expensive.
"rolled neck "
According to this our invention, we employ what is known as a
that is, a neck which is raised and formed from sheet metal and we fix the rolled
neck, and the upper spherical part together by an improved method as herein
described whereby it is difficult for the rolled neck and the upper spherical part to
become detached from each other or to work loose. We effect the union of the
upper spherical part, with the neck by making an outwardly projecting lip all
round the said hole or mouth of the sphere.
The extreme outer part of this lip is of larger diameter than the hole or mouth
so that, a groove is formed by the outside of the lip, at that point, where it merges
into the upper spherical part.
"
This lip may be formed by suitable dies or tools worked in a press or by other
means. The said lip is inserted in the open top of the "rolled or other sheet
metal neck, which latter is made of a size to fit tightly round the lip and the neck
is then firmly secured to the spherical upper part by closing or beading, the top
edge of the neck inwardly so as to engage tightly in the groove formed by the
lip. We also provide a cast or other solid metal pommel in the base of the
neck around which the neck is closed or rolled. This pommel has a screw threaded
hole formed in it for the purpose of attaching the knob or terminal ornament to
the pillar of the bedstead or cot, by means of the usual screw provided for the
purpose.

"
In order to effectually secure this pommel in the said rolled or other sheet metal
neck, we make an annular or other groove or recess, or grooves or recesses, in the
under surface of the pommel into which the metal of the neck is closed or pressed.
The top of the pommel fits against a shoulder formed by diminishing the diameter
of the neck at that part. In some cases we form the upper spherical part of the
knob without a lip round the mouth or opening of the same, but we then form the
lip on the upper part of the rolled. neck.
The lip of the neck, would in such case be entered into the mouth or opening of
the upper spherical part. The neck and the sphere are then held in suitable
clamps, while the lip of the neck is pressed tightly to engage with the mouth of
the upper spherical part.
In other cases we insert the lip of the neck into the mouth of the upper
spherical part, and then unite the parts by brazing or soldering.

page_text: DESCRIPTION OF THE DRAWINGS.
Figs. 1. 2. 3 are sections of bedstead knobs, constructed according to this our
invention.
Similar letters of reference indicate the same parts throughout the drawings.
A is the upper spherical part hereinafter called the "ball."
B is the rolled neck.
C is the cast pommel inserted into B.
Fig. 1 shews the ball A constructed with an outwardly projecting lip. The
upper part of the neck B is shewn pressed into and interlocking with the lip
formed on A.
Fig. 2 shews the ball A constructed without a lip. The upper part of the
neck B is provided with a lip as.shewn, which lip is pressed into and interlocked
with the ball A.
Fig. 3 shews the ball A constructed without a lip. The upper portion of the
neck B is formed with a flange lip, and the neck is united to the ball, by brazing or
soldering. C Figs. 1. 2. 3 shews the cast or solid metal pommel which is inserted
into the lower part of the neck B. This pommel C is formed with a groove or
recess on its underside, into which groove, the metal of the neck B is pressed, as
shewn in the drawings. This groove is provided with one or more projections as
shewn at D Figs. 1. 2. 3. The metal of the neck B is shewn pressed into close
contact with C and its projection D. The pommel C is therefore prevented from
turning round in the neck B.
Having now particularly described and ascertained the nature of our said inven-
tion and the manner in which the same is to be performed we declare that what we
olaim is
1st. In a knob or ornament for metallic bedsteads or cots, the combination of
a rolled metal neck with a cast metal pommel inserted in the neck, substantially
as described and illustrated by Figs. 1. 2. 3 of the drawings hereto annexed.
