Improvements in the Manufacture of Sheet Metal Ball-vases, Knobs,
and like Terminals for Metallic Bedsteads and other articles.
I, ALFRED WILLIAM HEATH, Assistant Managing Director to Samuel Heath
and Sons Limited, of Leopold Street, in the City of Birmingham, Manufacturers,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to the manufacture of sheet metal ball-vases, knobs, and
like terminals for metallic bedsteads, cots, fenders, curbs, and other articles, and
consists primarily in an improved method of securing the shell body part of a knob
or terminal, to the sheet metal neck, which is loaded at the base with a lead
pummel for receiving the screwing of the wormed pin upon which it takes.
In carrying out one form of the invention in connection with a two-part knob,
we take a three-quarter spherical or globular shell body part, with the edge of the
open mouth having a gap, wherethrough a corresponding outward key or cotter
bulging of the flange surmounting the summit of the sheet metal neck, takes,
and when the bulging is closed down or expanded from the inside by a hook
burnisher, the one part is fixedly secured to the other and is also prevented from
rotating thereon.
Thus, we form the base of a suitable shape by spinning or otherwise, with the
lower foot edge turned over the bottom edges of a lead pummel or loading, which
has a vertically directed and screwed hole formed axially within it for taking
upon the securing peg or screw of a bedstead or the like, whilst the upper end is
formed with an annular stop collar, upon or against which the edge of the open
mouth of the hollow or shell body part comes or rests. Above the rest collar is a
vertical flange, out of the walls of which the key bulging or cotter is formed,
which, after being introduced through the corresponding gap in the edge of the
open end of the shell, and flattened down to the inside contour of the said shell
by a hook burnisher or other suitable tool inserted up the axis of the neck, unites
the two parts of the knob together and prevents the component elements from
rotating upon one another.
According to another form of our invention, we make the neck and the lower
portion of the body as one part and the upper hemisphere or top end as the other
part, and unite them together and prevent them rotating or turning upon one
another, by a key bulging upon the enlarged or socket end or mouth of the one taking
into a corresponding gap in the socketting mouth of the other part and then being
flattened down or expanded upon the inside by an interiorly applied burnisher or
other tool.

and like Terminals for Metallic Bedsteads and other articles.
I, ALFRED WILLIAM HEATII, Assistant Managing Director to Samuel Heath
and Sons Limited, of Leopold Street, in the City of Birmingham, Manufacturers,
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 follow-
ing statement:-
This invention relates to the manufacture of sheet metal ball-vases, knobs, and
like terminals for metallic bedsteads, cots, fenders, curbs, and other articles, and
consists primarily in an improved method, in the case of a knob, of preventing
the rotation of the shell body part of a knob or terminal, upon the sheet metal
neck, after the parts have been secured together by the ordinary method of spinn-
ing or closing a part of the one over, within or around a part of the other; the
said necks being preferably loaded with a lead pummel the axial hole in which is
screwed to take onto the wormed attachment pin of the article upon which the knob
is mounted.
Figure 1 of the accompanying drawing represents a side elevation and an under-
side plan of the body part of a sheet metal knob, and Figure 2 represents like views
of a sheet metal knob foot or neck, said knob and foot being constructed according
to my invention and in such a manner that when the said parts are fitted and
secured together, they are incapable of relative rotation upon or with respect to
one another.
Figure 3 is a vertical section of the fitted together and finished knob.
Figure 4 is a side elevation thereof.
Figure 5 represents upon an enlarged scale, and partly in elevation and partly
in vertical section, the body and neck parts of the said knob fitted together, but
before being secured or made fast to one another by spinning or turning down an
annular upright flange at the top of the neck onto the metal at the inside of the
mouth of the body.
Figure 6 is a like view as Figure 5, but showing the parts permanently secured
together by the spinning of the flange of the neck down onto the inside edge of
the mouth of the body part.
The same letters of reference indicate corresponding parts in the said figures of
the drawing.
In carrying out this form of the invention in connection with a twopart knob.
I take a three-quarter spherical or globular shell body part a, with the edge a¹,
of the open mouth a³, having a gap or cut-out recess a³, wherethrough a correspond-
ing outward key or cotter bulging b, formed out of the metal of the upright flange b',
surmounting the summit of the sheet metal neck 62, takes, and when this flange
is spun over and the bulging is closed down or expanded from the inside by a hook
burnisher, introduced up the neck into the interior of the knob, the parts are fixedly
secured to each other and also prevented from rotating upon one another.
Thus, I form the base or neck 6, of a suitable shape by spinning or otherwise,
with the lower foot edge 63, turned over the bottom edges cl, of a lead pummel
or loading, which has a vertically directed and screwed hole c³, formed axially
within it for taking upon the securing peg or screw of a bedstead, or the like,
whilst the upper end is formed with an annular stop or rest collar 64, upon or against
which the aforesaid edge a¹, of the open mouth of the hollow or shell body part a,
comes or rests. Above the rest collar is the vertical flange b¹, out of the walls of
which the key or collar bit b, is formed by making a slight outward bulging at a

page_text: part thereof, and which, after being introduced through the corresponding gap a³,
in the edge of the open end of the shell, is flattened down to the inside contour of
the said shell, together with the rest of the said flange b', by a hook burnisher or
other suitable tool inserted up the axis of the neck, (whilst the same is being spun
or rotated) thus uniting the two parts of the knob together and preventing the
component elements from rotating upon one another.
According to another form of the invention, I may make the neck and the lower
portion of the body as one part and the upper hemisphere or top end of the body
as the other part, and unite the said two parts together and prevent them rotating
or turning upon one another, by a key bulging upon the enlarged or socket end or
mouth of the one taking into a corresponding gap in the socketting mouth of the
other part and then being flattened down or expanded upon the inside by an
interiorly applied burnisher or other tool.
The invention is also applicable to securing together and preventing rotation of
the component elements of various hollow articles made from sheet metal, such as
ball and other vases, terminal ornaments, spindles and the like for use upon bed-
steads, cots, fenders and similar articles.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In sheet-metal bedstead knobs, vases, terminals and analogous articles, in
which the component elements are united together by spinning or closing a part
or parts of the one into, over or around a part or parts of the other, preventing
the rotation of the united elements upon one another by a key, or key bulging of
the one taking into or engaging with a gap or recess in the other.
