PROVISIONAL SPECIFICATION.
Certain Improvements in the Manufacture of Door Knobs, Bedstead
Knobs, and other Knobs.
We, RICHARD COLLIER and EDWARD COLLIER, both of Stour Valley Works,
Barker Street, Parade, Birmingham, Wood Turners, do hereby declare the nature
of this invention to be as follows:-
-.
This invention consists of the hereindescribed improvements in the manufacture
of all kinds of knobs such for instance as knobs forming parts of lock and latch
furniture for doors, door centre knobs, shutter knobs, ornamental knobs for metallic
bedsteads and cots, and knobs for various kinds of culinary utensils and for other
purposes.
By our said invention we are enabled to make knobs cheaper and in some cases
stronger than heretofore.
One method of carrying out our said invention is as follows:-We make the
body of the knob of wood or of china or of papier machè and the neck of the knob
of metal or alloy, such as cast iron or other cast metal or alloy, or the neck may be
raised or otherwise formed from sheet metal or alloy. We fix the wooden or china
or papier machè body and the metal neck together so as to form a complete knob.
This we may do in various ways; for instance the neck may fit in a central hole in
the body and both be screw threaded and screwed tightly together and in order to
prevent their becoming unscrewed when in use they may be cemented together and
further secured by shrinking the body on to the neck during the process of stoving
the knob. Or the neck and the hole in the body in which the neck fits may be
roughened or one or both of them may have lateral projections which take into
corresponding recesses in the other of them so that they will engage firmly together.
Or we may employ other means for fixing the body and the neck together.
When a china knob is made with a metal neck as above described the neck is not
liable to break as are the necks of ordinary china knobs in which the body and neck
are made both together in one piece; and our improved china knobs made with
metal necks can be more securely attached to their spindles than can other china
knobs.
The said metal neck may either have a central longitudinal hole for attachment
to the spindle or the spindle may be permanently fixed to the neck according to the
particular purpose for which the knobs are required.
Or we may similarly make any of the said Knobs of a china or papier machè or
metal body fixed to a wooden neck with or without a metal mount at the base of
the neck; or we may make any of the knobs of a papier machè neck fixed to a
metal or china or wooden body.

COMPLETE SPECIFICATION.
Certain Improvements in the Manufacture of Door Knobs, Bedstead
Knobs, and other Knobs.
We, RICHARD COLLIER and EDWARD COLLIER, both of Stour Valley Works,
Barker Street, Parade, Birmingham, Wood Turners, 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 hereindescribed improvements in the manufacture

page_text: Or we may similarly make any of the said knobs of a china or papier machè
body A fixed to a wooden neck Ċ with or without an ordinary metal mount at the
base of the neck or we may make any of the knobs of a papier machè neck C fixed
as above described to a china or wooden body A.
Our invention is applied to other knobs similarly as above described with reference
to door knobs.
When our invention is applied to bedstead knobs such as shewn for instance by
Fig. 7 the bodies of these knobs may be (as other knobs are) covered by a shell of
thin brass closed around the body A.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In the manufacture of door knobs and other knobs making the knob body of
wood or of china or of papier machè separate from the neck of the knob the said
neck being made of metal fitting in the body and there secured in any of the several
ways substantially as herein before set forth.
2. In the manufacture of door knobs and other knobs making the knob body of
wood or of china separate from the neck of the knob the said neck being made of
papier machè fitting in the body and there secured in any of the several ways
substantially as hereinbefore set forth.
3. In the manufacture of door knobs and other knobs making the knob body of
china or of papier machè separate from the neck of the knob the said neck being
made of wood fitting in the body and there secured in any of the several ways
substantially as hereinbefore set forth.
