PROVISIONAL SPECIFICATION.
Certain Improvements in the Manufacture of Door and other Knobs,
and Terminal Ornaments.
I, EDWARD COLLIER, of Woodfield, Water Orton, Warwickshire, Wood Turner, do
hereby declare the nature of this Invention to be as follows:-
This Invention consists of the hereindescribed improvements in the manufacture
of door knobs and other knobs and terminal ornaments such for instance as knobs or
terminal ornaments for metallic bedsteads fenders and cornice poles.
Heretofore the said knobs and terminal ornaments to which my invention applies
have usually been made of a raised sheet metal shell formed of the required shape and
fixed to a metal neck or foot. When door knobs are made in this way it has been
found difficult to securely fix the said shell or body of the knob to the neck, and in
other cases, as for instance in terminal ornaments for cornice poles and metallic bed-
steads, the said shell part when made of thin metal is easily dented so as to spoil the
appearance of the same. By my Invention I effectually secure the shell and knob
proper to its neck and I also strengthen the shell part by an inner core as hereinafter
described.
I will describe my invention as applied to a door knob.
In carrying out my invention I form a spheriodal or other core of wood or other
suitable substance of about the same shape and size of the body part of the required
knob, and round this core 1 spin or otherwise close a sheet brass or other sheet inetal
shell so as to enclose the core. The neck of the knob is cast or otherwise made with
a central boss which is screw threaded outside and screwed into a central hole in the
core. The neck of the knob is also made with a flange or projecting arm or
arms to take against the body of the knob and this flange or the arm or arms is or
are made with one or more, preferably two, projecting pegs arranged so as to pierce
and enter the shell 'and the core when the neck is fixed thereto as hereinafter
described.
In order to fix the neck to the core covered by the thin brass or other metal shell
as above described, the screwed boss part of the neck is firmly screwed as far as it will
go into and cemented in the central hole in the core. The said flange or the arin or
arms are then by press tools or by other means pressed against the body of the knob
so that the said projection or projections will then pierce the shell and enter the core
and thus effectually prevent the neck from coming unscrewed from the body part of
the knob.
Or the said projecting arms of the neck may be dispensed with and the neck of the
knob be made to enter a recess in the core of the knob and be there secured by the
screwed boss as aforesaid and by one or more screws pegs or pins or the like passing
through the said core into the part of the neck of the knob which fits in the said recess.
Or the recess in the knob may be made with internal ratchet teeth with which a spring
or spring ratchet on the neck of the knob engages as it is being screwed in thus
preventing the neck from unscrewing out of the recess in the body of the knob.
The said screwed boss of the neck may if desired pass through the wooden core

page_text: part of the body of the knob and engage with a metal or other nut which is sunk into
the front part of the core before the shell is closed on the same.
In a further modification of my Invention the core or body part of the knob is
provided with a projecting boss which is screwed into or on to the neck of the knob.
This boss can conveniently be formed of a piece of tube which is fixed in the central
hole of the core before or after the shell is closed on the same the front end of the
said tube being by preference made with an outwardly projecting part to take against
the front of the knob and effectually prevent the tube from being pulled out of the
knob.
Instead of the projection or projections being formed with the flange or arm or
arms of the knob as above described, the said flange or arin or arms may have a hole
through which a screw or pin is passed into the shell and body of the knob to effect-
ually prevent the neck from becoming unscrewed therefrom or turning independently
of the body or shell.
By making the shell, with a wooden or other solid core as above described the
liability to be dented by a blow is minimised.
My Invention is applied to the manufacture of other kinds of knobs or terminable
ornaments similarly as above described with reference to a door knob.

Certain Improvements in the Manufacture of Door and other Knobs,
and Terminal Ornaments.
I, EDWARD COLLIER, of Woodfield, Water Orton, Warwickshire, Wood Turner,
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 consists of the herein described improvements in the manufacture
of door knobs and other knobs and terminal ornaments such for instance as knobs or
terminal ornaments for metallic bedsteads fenders and cornice poles.
. Heretofore the said knobs and terminal ornaments to which my invention applies
have usually been made of a raised sheet metal shell formed of the required shape
and fixed to a metal neck or foot. When door knobs are made in this way it has
been found difficult to securely fix the said shell or body of the knob to the neck, and
in other cases, as for instance in terminal ornaments for cornice poles and metallic
bedsteads, the said shell part when made of thin metal is easily dented so as to spoil
the appearance of the same. By my invention I effectually secure the shell and
knob proper to its neck and I also strengthen the shell part by an inner core as
hereinafter described.
I will describe my Invention as applied to a door knob and refer to the
accompanying drawings on which
Fig. 1 is a sectional elevation of a door knob constructed according to this
Invention;
Fig. 2 shews the same parts as Fig. 1 but with the securing of them together not
completed;
Fig. 3 shews the body part of the said knob and the neck separately before being
fixed together;
Fig. 3 is a sectional elevation and plan of a modified form of the neck part of the
knob ;

broken away so as to shew the interior;
Fig. 9 is a sectional elevation of a door knob illustrating a further modification of
my Invention and
Fig. 10 is a sectional elevation of a door knob illustrating another modification.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings..
I will first refer more particularly to the arrangement of my Invention illustrated
by Figs. 1, 2, 3 and 3. In carrying-out my Invention I form a spheroidal or other
core A of wood or other suitable substance of about the same shape and size as is
the body part of the required knob and round this core I spin or otherwise close a
sheet brass or other sheet metal shell B so as to enclose the core A The neck C of
the knob is cast or otherwise made with a central boss c¹ which is screw threaded
outside and screwed into a central hole al in the core A. The neck C of the knob is
also made with a flange e (see Figs 1, 2, and 3) or with a projecting arm or arms e
(see Fig. 3) to take against the body A of the knob and this flange c or the arms eis
or are made with one or more preferably two projecting pegs e arranged so as to pierce
and enter the shell B and the core A when the neck C is fixed thereto as hereinafter
described.
In order to fix the neck C to the core A covered by the thin brass or other metal
shell B as above described, the screwed boss part c¹ of the neck C is firmly screwed
as far as it will go into and cemented in the central hole a¹ of the core A as shown
in Fig. 2. The said flange c2 or the arm or arms c³ are then by press tools or by
other means pressed against the body A B of the knob so that the said projection
or projections c will then pierce the shell B and core A as represented by Fig. 1
and thus effectually prevent the neck C from cotning unscrewed from the body
part A B of the knob...
I may dispense with the projections and instead theroef prevent the neck of
the knob from becoming unscrewed from the body by the neck C being made to
enter a recess 2 (see Fig. 4) in the core of the knob and there secured by the
screwed boss c being screwed into the hole a¹ of the core A as aforesaid and by
one or more screw pegs or pins d or the like passing through the shell B and
core A into the part of the neck C of the knob which fits in the said recess a².
In a further modification of. my Invention illustrated by Figs. 5 and 6, the
recess in the knob is made with internal ratchet teeth E (see Fig. 5) which
may be formed by spinning the shell B. into the recess a² and then forming the
teeth or roughened surfaces e by a milling tool whilst the body A 13 of the knob
is revolving in a lathe. This collar part c of the neck C of the knob which fits
in the recess 2 is made with a spring or spring ratchet f which as the neck C is
being screwed into the body engages with the ratchet teeth e and thus prevents
the neck C from unscrewing.
Instead of the screwed boss c¹ of the neck of the knob engaging with a screw
thread formed in the core A as in the examples above described, the screwed
part of the neck C may if desired pass through the wooden core part A of the
body of the knob and engage with a metal or other nut g (see Figs. 7 and 8) which
is inserted in the front part of the core A before the shell B is closed on the same.
In the arrangement of my Invention illustrated by Fig. 9 the core or body A of
the knob A is provided with an internal piece of tube H which is fixed in the
central hole of the core A preferably before the shell B is closed on the same
the front end of the said tube H being enlarged to take against the front of the

page_text: .
knob and effectually prevent the tube H from being pulled ont of the knob. The
boss c¹ of the neck C is screwed into this tube H as shewn in Fig. 9.
or
Instead of the projection or projections being formed on the flange
arm or arms c3 of the neck of the knob as above described, the said flange c² or
the arm or arms c may (see Fig. 10) have a hole or holes ii through each
of which a screw or pin such as is passed into the shell B and body A of the
knob to effectually prevent the neck C from becoming unscrewed therefrom or
turning independently of the body or shell A.
By making the shell B with a wooden or other solid core A as above described
the liability to be dented by a blow is minimised. My Invention is applied to
the manufacture of other kinds of knobs or terminal ornaments similarly as above
described with reference to a door knob.
I have not illustrated or described any method of securing the door knob on
its spindle as such means form no part of my Invention which is applicable to all
kinds of knobs and terminal ornaments no matter what particular means are
employed for securing them to their spindles.
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: -
1. In a door knob or other knob or terminal ornament the combination of a wooden
or other core, a sheet metal shell spun or otherwise closed round said core and a
metal neck screwed into said core or into a nut or tube fixed therein and provided
with any of the means substantially as hereinbefore described with reference to the
accompanying drawings for preventing the neck from coming unscrewed from the
body of the knob as hereinbefore set forth.
2. In a door knob or other knob or terminal ornament the combination of a wooden
or other core, a sheet metal shell spun or otherwise closed round said core, and a
metal neck screwed into said core and provided with a flange or an arm or arms made
