PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metallic Terminal Ornaments
and Knobs for Bedsteads, Doors, and other articles.
I, MARK LAWTON, of Harford Street, in the City of Birmingham, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention pertains to means for putting or securing together without
soldering, certain component parts of the said terminal ornaments and knobs.
Heretofore, the lower half of the head, or the lower or body shell of a spherical
or bulbous top or head, has been connected to the neck, by hard soldering or
brazing.
In carrying out one form of my invention, in connection with a terminal
ornament, I make the spherical part of the said ornament, of two hollow
hemispheres, jointed together by burnishing or turning the meeting edges of one
hemisphere, over the meeting edges of the other.
The lower hollow hemisphere or half of the said bulbous termination, is connected
to the summit of the neck, by a tongue or key shaped part of the one, taking into
a like shaped gap or opening made in the other.
Thus the foot or base of the lower half or hemisphere is pierced with a circular
hole, about its middle, with a tongue, key, or bit directed inwardly from its side,
and which tongue, key or bit, takes into a like shaped gap or opening, made or cut
within an upright flange (of the inside diameter of the circular piercing) directed
from the top side of a collar, disposed circumferentially around the summit part of
the neck.
This said upright flange, extends beyond the metal of the lower half shell
adjacent to it, so that by turning outwardly the top boundary edge of the said
flange of the neck, onto and over the boundary edge of the piercing of the lower
half part union is made, or the parts are connected together.
The turning over of the metal of the flange, with the underside of the boundary
edge of the piercing resting upon the collar makes the connection, whilst the
tongue, key or piece, prevents the said connecting parts from rotating or turning.
The turning over of the flange is performed by a vertical punch or tool, directed
through the uncovered top of the lower half, but when the said top is covered in,
or is made of a complete sphere, then, I propose to turn over the said flange, by
the introduction of a cranked punch or tool, through a side piercing, which is made
for the passing of a rail or other object therethrough.
Although I have described my invention as applied to terminal ornaments,
composed of spherical and bulbous parts, yet my invention is applicable to the
manufacture of ball and other knobs, and also ball and other ornaments.

Improvements in the Manufacture of Metallic Terminal Ornaments
and Knobs for Bedsteads, Doors, and other articles.
I, MARK LAWTON, of Harford Street, in the City of Birmingham, Manufacturer,
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 pertains to means for putting together or securing together,
without soldering, certain component parts of the said terminal ornaments and
knobs.
Heretofore, the lower half of the head, or the lower or body shell of a spherical
or bulbous top or head, has been connected to the neck, by hard soldering or
brazing.
In carrying out one form of my invention, in connection with a terminal
ornament, I make the spherical part of the said ornament, of two hollow
hemispheres, or of two shells, connected together by burnishing or turning the
meeting edges of one hemisphere or shell, over the meeting edges of the other.
The lower hollow hemisphere or shell or half of the said bulbous termination, is
connected to the summit of the neck, by a tongue or key shaped part of the one,
taking into a like shaped gap or opening made in the other.
Thus, the foot or base of the lower half or hemisphere, is pierced with a circular
hole about its middle, with a tongue, key or bit directed inwardly from its side,
and which tongue, key, or bit, takes into a like shaped gap or opening, made or
cut within an upright flange (of the middle diameter of the circular piercing)
directed from the top side of a collar, disposed circumferentially around the summit.
part of the neck.
This said upright flange, extends beyond the metal of the lower half shell
adjacent to it, so that by turning outwardly the top boundary edge of the said
flange of the neck, onto and over the boundary edge of the piercing of the lower
part, a union is made, or the parts are connected together.
The turning over of the metal of the flange, with the underside of the boundary
edge of the piercing resting upon the collar, makes the connection, whilst the
tongue, key or piece, prevents the said connecting parts from rotating or turning.
The turning over of the flange is performed by a vertical punch or tool, directed
through the uncovered top of the lower half, but when the said top is covered in,
or is made of a complete sphere, then I propose to turn over the said flange, by the
introduction of a cranked punch or tool, through a side piercing, which is made for
the passing of a rail or other object therethrough.
Although I have described my invention as applied to terminal ornaments,
. composed of spherical and bulbous parts, yet my invention is applicable to the
manufacture of ball and other knobs, and also hall and other ornaments.
Figure 1 of the accompanying drawing represents, partly in elevation, and partly
in vertical section, a bedstead or other terminal or ornament made or put together
according to my invention.
Figure 2 represents a like elevation and sectional view as Figure 1, but with the
said terminal ornament turned round to a position at right angles to the said
figure, so as to exhibit how the tongue, key or connector of the neck part to the
body part, is turned over and inwards into a gap, hence the connection of the neck
part to the body part.
Figure 3 represents a transverse section of Figure 2 upon the dotted lines A. B.
Figure 4 represents partly in section and partly in elevation, the component
part of the said terminal or knob separately and prior to their connection
together.
Figure 5 represents a hacktend elevation ofthe nook •

page_text: Figure 6 is an interposed washer, and
Figure 7 is a back end elevation of the shoulder shell body part.
The same letters of reference indicate corresponding parts in the several figures-
of the drawing.
The said terminal or ornament is composed of a cast or other neck a, united to the
shoulder shell body part b, as hereinafter described, and a crown shell body part c..
The neck part consist of a pummel or foot a', and an inner or top end a³, having a
circumferential flange a, directed from the face a', of the said inner or upper
end a, and which flange or part circumferential flange a³, has a gap a', wherein a
tongue, key or bit 3, directed inwardly from the inner boundary edge ¹, of the-
middle piercing, of the shoulder body shell b, takes, and thereby prevents the
rotation of the said shoulder body part upon the neck, or otherwise, the neck within.
or upon the body.
The piercing of the said shell part, has an inside diameter equal or about.
equal to the outside diameter a, of the outstanding collar a³, so that on the said
collar being closed over or turned outwardly, with the interposed washer d
between the metal of the edge ', and the outside aº, of the flange a³, the said neck.
and body parts are united together, and the one prevented from rotating upon or
within the other.
The crown or end shell part e, is connected to the shoulder body part 6, by a.
spinning or burnishing process commonly known.
The flange a, instead of being turned upon an interposed washer d, may be
turned upon the metal of the inside edge b', of the shoulder shell b.
Figure 8 represents a modified form of my invention; in this arrangement which.
is the converse to that described, the tongue, key or bit is upon the neck, whilst
the gap is within the shoulder body part.
Figure 9 represents an inside end view of the neck; Figure 10 is an end view
of the shoulder shell body part.
a is the neck, with a circumferential collar a³, cross cut at a, and from which
cross cut part, a tongue, key or bit a' is formed, by forcing the same slightly
outwards, so as to extend beyond the outside diameter a, and is adapted to take
within the key-way or gap 2, formed within the boundary edge 6, of the middle.
opening or piercing &, of the shoulder shell body part b.
The
h
are put together by dropping the part upon the part a, or vice versa
parts
and with the tongue, key or bit a' taking into the gap or tongue-way b', and then
by closing, turning over, or bulging outwards the collar a³, the said parts are both
united together and prevented from rotating.
Figure 11 represents a further form of my invention. In this arrangement, a
projection, key or the like on the neck part takes into a depression or sinking inade
in the opposed face of the shoulder shell body part.
Thus a is the neck, and the shell body part to which the same is to be con-
nected. The neck a has upon the inner or top side of it, a projection, key or the
like a, which takes within a like shaped sunken depression, formed or sunken
within the opposed face of the shell part b, and adjacent to the boundary edge of
the piercing (see Figure 12, which is a plan of the said part b).
Instead of the bulge, projection, key or the like a', being upon the opposed face
of the shoulder a, the said bulge may be upon the opposed face b, and with the
said projection taking into a like shaped depression in the opposed face or part of
the neck a.
The closing or turning inwards of the collar, as in the previous arrangements,.
unites the parts together, whilst the key and depression parts prevent rotation.
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 The improvements in the manufacture of metallic ornaments, knobs and
other articles of a like manufacture, preventing the component, sectional and united.

page_text: or connected together parts from turning or rotating, by a tongue, key, projection
or bit upon the one part, engaging or taking within a gap, hole, indentation or the
like of the other part, substantially as described and set forth.
Secondly-The improvements in the manufacture of metallic ornaments, knobs
and other articles of a like manufacture, uniting or connecting together and pre-
venting the rotation of the component parts of the said articles, (when made of two
or more parts) by a flange of the one part being turned over the metal of the
boundary edge of the other part, and with a tongue, key or bit of the second-named
part engaging within a gap cut out of the turned over flange of the other part,
substantially as described and set forth in Figures 1 to 7.
Thirdly-The improvements in the manufacture of metallic ornaments, knobs
and other articles of a like manufacture, uniting or connecting together, and pre-
venting the rotation of the component parts of the said articles (when made in
two or more parts), by a flange of the one part being turned over the metal of the
boundary edge of the other part, and with a tongue, key or bit of the said flanged
part or its equivalent, taking into a gap, hole or opening in the said second named
part, substantially as described and set forth in Figures 8, 9, and 10.
Fourthly-The improvements in the manufacture of metallic ornaments, knobs
and other articles of a like manufacture, uniting or connecting together, and pre-
venting the rotation of, the component parts of the said articles, (when made in
two or more parts) by a flange of the one part being turned over the metal of the
boundary edge of the other part, and with a snug on the part carried by the flange
taking within a seating or depression in the other part, substantially as described
and set forth in Figures 11 and 12.
