page_text: I, JOHN PARRY, of the Eagle Foundry, Broad Street, Birmingham, Warwickshire,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My Invention has reference chiefly to bedstead knobs or terminals but it is
applicable also to door knobs and other knobs for useful or ornamental purposes.
In making a knob according to my Invention I take a hard core of porcelain or
other baked clay or wood or other suitable non-metallic material of spherical or
other regular bulbous form which can be turned in a lathe and of a shape and size
similar to the body of the required knob and preferably having a small hole
running from side to side and forming its axis. I take also a cup-shaped shell of
sheet brass or other suitable metal or alloy formed by spinning or stamping and
having formed therewith or attached thereto a neck for attachment of the knob.
Such neck may either be screwed or have a spindle fixed thereto or it may have a
square or round hole or other means for attachment of the knob according to the
particular purpose for which the knob is required. The said cup-shaped shell is
made to fit, and is rather larger than, one half of the said bulbous core. place
the said core in the shell and by spinning in a lathe or by tools worked in a press
or other suitable means I spin or press the rim of the shell so as to diminish it in
diameter and close it around the largest part of the core so that the core and the
shell will thereby be firmly attached together. Nearly half of the said core will
protrude from the shell and so give an ornamental appearance to the knob.
I prefer to more securely fix the core to the shell by passing a pin through the
shell and the core from side to side which pin may then be rivetted over and
secured; or instead of the said pin and for the same purpose the shell may be
indented or pressed into a hole or holes provided in the core.
That part of the core which protrudes from the shell as above described may be
covered by a shell, which I call a second shell, made to fit and rather larger than
one half of the said core. The said second shell may either be attached to the core
by being pressed or spun around its largest part before the core is attached to the
first shell, or, the first shell may be attached to the core as above described and the
second shell attached by spinning or pressing afterwards.
When for ornamental or other purposes a neck or projection is required to be
formed with or attached to the second shell I prefer to form or attach such neck or
projection before the second shell is attached to the core,

page_text: Either the first or second shell or both may be perforated in any desired pattern
so that the core will shew through such perforations thereby adding considerably
to the ornamental appearance of the knob; and for the same purpose the rim of
one or both of the shells may be serrated, scalloped or ornamented in any other
manner.
Instead of spinning the cup-shaped shell partly around the bulbous core after
the neck has been attached thereto as herein before described I sometimes spin the
cup-shaped shell around the bulbous core before the neck is attached thereto and
then attach the shell and the neck together by spinning so as together to wholly
cover the bulbous core.
By constructing knobs with a hard core as above described they are stronger and
more solid than hollow sheet metal knobs as Dow ordinarily made.

page_text: Improvements in the Manufacture of Bedstead and other Knobs.
I, JOHN PARRY, of the Eagle Foundry, Broad Street, Birmingham, Warwickshire,
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:-
My Invention has reference chiefly to bedstead knobs or terminals but it is.
applicable also to door knobs and other knobs for useful or ornamental purposes.
In making a knob according to my Invention I take a hard core of porcelain or
other baked clay or wood or other suitable non-metallic material of spherical or
other regular bulbous form which can be turned in a lathe and of a shape and size
similar to the body of the required knob and preferably having a small hole
running from side to side and forming its axis. I take also a cup-shaped shell of
sheet brass or other suitable metal or alloy formed by spinning or stamping and
having formed therewith or attached thereto a neck for attachment of the knob.
Such neck may either be screwed or have a spindle fixed thereto or it may have a
square or round hole or other means for attachment of the knob according to the
particular purpose for which the knob is required. The said cup-shaped shell is
made to fit, and is rather larger than, one half of the said bulbous core.
I place
the said core in the shell and by spinning in a lathe or by tools worked in a press
or other suitable means I spin or press the rim of the shell so as to diminish it in
diameter and close it around the largest part of the core so that the core and the
shell will thereby be firmly attached together. Nearly half of the said core will
protrude from the shell and so give an ornamental appearance to the knob..
I prefer to more securely fix the core to the shell by passing a pin through the
shell and the core from side to side which pin may then be rivetted over and
secured; or instead of the said pin and for the same purpose the shell may be
indented or pressed into a hole or holes provided in the core.
That part of the core which protrudes from the shell as above described may be
covered by a shell, which I will call a second shell, made to fit and rather larger
than one balf of the said core. The said second, shell may either be attached to
the core by being pressed or spun around its largest part before the core is attached
to the first shell, or, the first shell may be attached to the core as above described
and the second shell attached by spinning or pressing afterwards.
Fig. 1 of the accompanying drawings represents two views of a spherical core
forming part of a knob made according to my Invention; Fig. 2 represents in
front elevation and Fig. 3 in plan a cup-shaped shell for forming with the core
represented by Fig. 1, the knob represented in elevation by Fig. 4 and in plan by
Fig. 5; Figs. 6 and 7 are modifications of the same.
a is a spherical hard core of porcelain or other baked clay or wood or other
suitable non-metallic material which may be of other like regular bulbous form of
a shape and size similar to the body of the required knob and having a small hole b
running from side to side and forming its axis. c is a cup-shaped shell of sheep

page_text: brass or other suitable metal or alloy formed in any ordinary manner by spinning
or stamping and having a neck d preferably of cast metal attached thereto by
spinning or pressing in the ordinary way or the neck d may be of sheet metal and
formed with the shell c. The central hole e in the neck d may either be screw
threaded as shewn in Fig. 2 for its attachment or made square or round or have a
spindle fixed thereto as knobs are now made according to the particular purpose for
which it is to be used. The shell c is made to fit the core a but the rim c¹ of the
former extends a little over the largest part of the latter (see Fig. 2) and when the
core a has been placed in the cup c its rim c¹ is spun or pressed over the largest
part of the core à (see Figs. 4 and 5) so as to hold the core and the shell together
leaving nearly half of the core protruding from the shell which will then have an
ornamental appearance. The core a and the shell c may be more securely fixed
together by passing a pin f through both (see Fig. 6) and rivetting over the ends;
or the shell c may be indented at c' and pressed into a hole b or holes provided in
the core a as shewn by Fig. 7.
.
Fig. 8 represents in sectional elevation a second shell for covering that part of
the core which protrudes from the first shell as shewn in elevation and plan by
Figs. 9 and 10; Fig. 11 represents in sectional elevation and Fig. 12 in elevation a
complete knob having the core wholly covered (except where perforated) and
Figs. 13 and 14 represent similar views of a modification of the same.
g Fig. 8 is
a second shell by which the part of the core a which protrudes from the shell c
may be covered. The second shell g is made to fit the core a to which it can be
attached by spinning or pressing its edge round the largest part of the core a
before the core a is attached to the shell c (see Figs. 9 and 10) the core a and the
second shell g being then attached to the first shell c by spinning or pressing the
rim of the shell c round the largest part of the core a (see Figs. 11 and 12); or
the shell c may first be attached to the core a as described with reference to
Figs. 1 to 7, both inclusive, and the second shell 9 attached to the core a by
spinning or pressing afterwards (see Figs. 13 and 14).
When for ornamental or other purposes a neck or projection is required to be
formed with or attached to the second shell I prefer to form or attach such neck
or projection before the second shell is attached to the core. Fig. 15 represents in
elevation and Fig. 16 in plan a knob made according to my Invention and having
a neck or projection attached to or formed with the second shell and Figa. 17, 18
and 19 represent parts of the same separately. The neck or projection h is
attached to the second shell g by means of spinning in a lathe or by ordinary tools
worked in a press, or is formed with the shell g, before the latter is attached to the
first shell c.
Instead of spinning the cup-shaped shell partly around the bulbous core after the
neck has been attached thereto as hereinbefore described I sometimes spin the cup-
shaped shell around the bulbous core before the neck is attached thereto and then
attach the shell and the neck together by spinning so as together to wholly cover
the bulbous core. Figs. 20, 21, 22 and 23 illustrate the manufacture of a modified
form of knob having the shell and neck connected together after the shell has been
spun around the bulbous core. Fig. 20 represents the finished knob which is
formed by spinning or pressing the cup-shaped shell (Fig. 1) around the core a
(Figs. 22 and 23) and then attaching the shell i and the neck d together by means
of spinning in a lathe or by ordinary tools worked in a press so as to wholly cover
the core a.
Either the first or second shell or both may be perforated in any desired pattern,
for instance by the holes k, so that the core a will shew through such perforations
thereby adding considerably to the ornamental appearance of the knob; and for
the same purpose the rim of one or both of the shells may be serrated, scalloped or
ornamented in any other manner for instance as shewn by Figs. 4, 12 and 14.
It will be evident that the shape of the regular bulbous core a can be greatly
modified without departing from the nature of my Invention, those cores illustrated
by my drawings being intended as examples.only.

page_text: By constructing knobs with a hard core as above described they are stronger and
more solid than hollow sheet metal knobs as now ordinarily made.
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:
Firstly. The improvements in the manufacture of bedstead and other knobs
hereinbefore described and illustrated in the accompanying drawings, that is to say,
making the said knobs of two essential parts namely, firstly, a cup-shaped shell,
having formed therewith or attached thereto the neck part of the knob, and
secondly, a bulbous core as herein described the said bulbous core being either
exposed or covered by a second shell, the shell or shells and the core being attached
together so as to form a solid knob as herein before described and illustrated.
Secondly. A knob constructed as herein described and illustrated by Figs. 1, 2,
3, 4, 5, 6 and 7 of the accompanying drawings, that is to say, a knob consisting of
a cup-shaped shell c having a neck d, and a regular bulbous core a, the said core a
and the cup-shaped shell c being attached together to form a solid knob substan-
tially as described and illustrated.
Thirdly. A knob constructed as herein described and illustrated by Figs. 8, 9, 10,
11, 12, 13 and 14 of the accompanying drawings, that is to say, a knob consisting
of a cup-shaped shell c having a neck d, a regular bulbous core a, and a shell g for
covering that part of the core a which protrudes from the shell o, the said core a
and the cup-shaped shells cand g being attached together so as to form a solid knob
substantially as described and illustrated.
Fourthly. A knob constructed as herein described and illustrated by Figs. 15, 16,
17, 18 and 19 of the accompanying drawings, that is to say, a knob consisting of a
cup-shaped shell c having a neck d, a regular bulbous core a, and a shell g having
a neck or projection h, the cup-shaped shells c and g and the core a being attached
together so as to form a solid knob substantially as described and illustrated.
Fifthly. A knob constructed as herein described and illustrated by Figs. 20, 21,
22 and 23 of the accompanying drawings, that is to say, a knob consisting of a
cup-shaped shell i, a neck piece d and a core a attached together so as to form a
solid knob substantially as described and illustrated.
