Improvements in the Ornamenting of Knobs or other Articles of
Circular Transverse Section.
I, ANN JANE JACKSON (the wife of Robert Harry Jackson), of No. 3, Moss
Road, Winnington, Northwich, in the County of Chester, do hereby declare the
nature of this invention to be as follows:-
The making of knobs and other articles as herein described so as that if such
a knob or other article be held before the eye it will present two profiles or
outline representations of a human or other face or other object suitable to be
representeil in profile, and so that, if revolved or twirled upon an axis identical
with or parallel to the line which would form the axis. of the knob or other article
if it were being turned in a lathe it (the knob or other article) will at every
period and throughout the whole of the revolutions or twirlings present to the
eye two views of the profile produced on such knob or other article, one profile
on the right of the knob or other article and one on the left and back to back.
Each knob or other article can represent only one face or other object, but the
profiles can be varied on different knobs or other articles.
The metliod of manufacturing such knobs or other articles will vary according
to the nature of the material employed in such manufacture; thus wood or
materials suitable for turning can be turned, materials suitable for casting or
moulding can be cast or moulded and possibly some materials would need to be
cut or carved or filed or worked by hand or otherwise.
To illustrate a simple method of producing a knoli sucli as is herein described'
I will suppose that the material to be used in its production is wood suitable for.
turning in a lathe. The wood being made to revolve in the lathe the person
making the knob will cut the revolving wood in the shape or likeness of the
profile to be produced and every line or mark made by the tool employed will
extend completely round the knob in a circle having for its.centre a point on
the axis on which the knob turns in the lathe.
In making a knob or other article of material requiring to be cast or moulded
a cast or mould will be used which will produce completely round the knob or
other article every line necessary to be made in tlie representation of the profile
to be produced.
In fine, whatever the method employed of working the material in use,, the
object to lie attained is the continuation round the knob or other article, (in
circles having each for its centre the line which would form the axis of the knob
if it were being turned in a lathe), of every line necessary for the representation
of the profile to be produced.
The method of producing circular profiles such as are herein described may be
used in the production of any article whether the same be a knob or not to which
such method is suitable or applicable.

I, ANN JANE JACKSON (the wife of Robert Harry Jackson), of Number 3, Moss
Road, Winnington, Northwich, in the County of Chester, 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:-
The making of knobs and, other articles as herein described, so as that if such
a knob or other article be held before the eye it will present two profiles or
outline representations of a human or other face or other object suitable to be
represented in profile, and so that if revolved or twirled upon an axis identical
with or parallel to the line which would form the axis of the knob or other article
if it were being turned in a lathe it (the knob or other article) will at every
period and throughout the whole of the revolutions or twirlings present to the
eve two views of the profile produced on such knob or other article one profile
on the right of the knob or other article and one on the left and back to back.
Each knob or other article can represent only one face or other object but the
profiles can be varied on different knobs or other articles.
The method of manufacturing sucli knobs or other articles will vary according
to the nature of the material employed in such manufacture; thus wood or
materials suitable for turning can be turned, materials suitable for casting or
moulding can he cast or moulded and possibly some materials would need to be
cut or carved or filed or worked by hand or otherwise.
To illustrate a simple method of producing a knob such as is herein described
I will suppose that the material to be used in its production is wood suitable for
turning in a lathe. The wood being made to revolve in the lathe the person
making the knob will ent the revolving wood in the shape or likeness of the
profile to be produced and every line or mark made by the tool employed will
extend completely round the knob in a circle having for its centre a point on
the axis on which the knob turns in the lathe.
In making a knob or other article of material requiring to be cast or moulded
a cast or mould will be used which will produce completely round the knob or
other article every line necessary to be made in the representation of the profile
to be produced.
In fine whatever the method employed of working the material in use, the
object to be attained is the continuation round the knob or other article (in
circles having each for its centre the line which would form the axis of the knob
if it were being turned in a lathe), of every line necessary for the representation
of the profile to be produced.
The method of producing circular profiles such as are herein described may be
used in the production of any article whether the same be a knob or not to which
such method is suitable or applicable..
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:-
:―
1
The herein described method of making knobs or other articles of circular
transverse section so as to represent profiles of human or other faces or other
objects suitable to be represented in profile.
