PROVISIONAL SPECIFICATION left by the said Tertius John Cooke at
the Office of the Commissioners of Patents, with his Petition, on the
2nd May 1857.
I, TERTIUS JOHN COOKE, of Wolverhampton, in the County of Stafford,
Gentleman, do hereby declare the nature of. the said Invention for "IM-
PROVEMENTS IN THE MANUFACTURE OF KNOBS, ROSES, AND ESCUTCHEONS USED FOR
DOORS, DRAWERS, SHUTTERS, AND OTHER SIMILAR PURPOSES," to be as follows:-
This Invention consists in making door knobs, shutter knobs, drawer knobs,
and cupboard turn knobs, and every other description of door knobs, of part
cast brass and part sheet iron, the roses and escutcheons being formed of sheet
iron only, and of japanning, enamelling, painting, laying in of pearl shell or
any other ornament, or otherwise illuminating the same on the surface, or
such part or portion of the knob as may consist of iron, and of burnishing. the
remainder of such knob, or part thereof as consists of cast brass; and also of
making, all such knobs partly of cast malleable iron or common cast iron and
part sheet iron, and of attaching both parts together by pressure, soldering,

page_text: brazing, casting, or otherwise, and afterwards japanning, enamelling, painting,
laying in of pearl shell or any other ornament, or otherwise illuminating the
same; also in enamelling, japanning, painting, laying in of pearl shell or any
other ornament in knobs, roses, & escutcheons of the ordinary description of
manufacture, the knobs being made of part cast brass and sheet brass, and the
roses and escutcheons of sheet brass or cast brass.
SPECIFICATION in pursuance of the conditions of tho Letters Patent, filed
by the said Tertius John Cooke in the Great Seal Patent Office on the
31st October 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, TERTIUS
JOHN COOKE, of Wolverhampton, in the County of Stafford, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Tertius John Cooke, Her special licence that I, the said Tertius John Cooke,
my executors, administrators, and assigns, or such others as I, the said Tertius
John Cooke, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF KNOBS, ROSES, AND ESCUTCHEONS USED FOR DOORS, DRAWERS, SHUTTERS,
AND OTHER SIMILAR PURPOSES," upon the condition (amongst others) that I, the
said Tertius John Cooke, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Tertius John Cooke, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say :-
This Invention consists in making door knobs, shutter knobs, drawer knobs,
and cupboard turn knobs, and every other description of door knobs, of part

page_text: cast brass and part sheet iron, or part cast iron and the rest sheet brass, the
roses and escutcheons being formed of sheet iron only or cast iron, and of
japanning, enamelling, ornamentally painting, laying in of pearl shell or any
other ornament,, or otherwise illuminating the same on the surface, or such
part or portion of the knob as may consist of iron, and of burnishing or
bronzing the remainder of such knob or part thereof as consists of cast brass;
and also of making all such knobs partly of cast malleable iron or common
cast iron and part sheet iron, and of attaching both parts together by pressure,
soldering, brazing, casting, or otherwise, and afterwards japanning, enamelling,
ornamentally painting, laying in of pearl shell or any other ornament, or
otherwise illuminating the same; also in enamelling. japanning, ornamentally
painting, laying in of pearl shell or any other ornament in knobs, roses,
escutcheons of the ordinary description of manufacture, the knobs being made
of part cast brass and sheet brass, and the roses and escutcheons of sheet
brass or cast brass.
The mode of manufacture is as follows:-In making the compound knobs,
or those composed of sheet iron and brass, the face or that part called the top
of the knob is first stamped or pressed by any of the ordinary methods practised
for stamping iron, by which a thin shell of iron, cupped or hollowed into a
hemispherical form, is produced. The neck of the knob, previously cast in
brass, is then secured to this shell by soldering, brazing, pressure in dies, or
other suitable means, making the form of the knob complete. The entire
surface of the iron shell is then japanned by any of the ordinary processes,
and whilst the japan is in a plastic condition the inlaying of pearl shell or
other ornamentation intended to be inlaid is to be done. The articles are
then stoved to harden the japan, after which the knob is placed in the chock
of a lathe and polished on a "buff." The brass neck of the knob is also
turned in a lathe to remove any irregularities left in the casting, and after-
wards burnished, or polished, or bronzed, according to taste. When I desire
to ornament these knobs with coloured designs, the japan is stoved or
hardened previous to adding the ornamentation, which is to be then applied
by hand or other suitable means, as now practised in the illuminating or
ornamenting japanned articles, and which operation being well known need
not be further particularized. The roses and escutcheons which are formed
of sheet iron alone are produced in the same manner as the shells for the
kuobs, and similarly treated in ornamenting them. I also manufacture knobs
for the purposes above named, but of a somewhat commoner description, by
casting the necks of malleable iron or even common cast iron and uniting
such necks- to shells of sheet iron, as above described, by pressure, soldering,

page_text: brazing, casting, or in any other suitable means, afterwards ornamenting such
knobs in manner already described. I also apply the same mode of orna-
mentation to the ordinary knobs, roses; and escotcheons now made, in which
the knobs are formed partly of 'sheet brass and partly of cast brass, or wholly
of cast brass, and the roses and escutcheons of sheet brass or cast brass.
Having thus described the nature of my said Invention, and in what manner
the same is to be performed, I wish it to be understood that I claim the im-
provements described in the manufacture of knobs, roses, and escotcheons used
for doors, drawers, and other purposes, the knobs being made partly of brass
and partly of sheet iron, or partly of cast iron and partly of sheet brass, or
partly of cast or malleable iron and the remainder of sheet iron, and the
roses and escotcheons solely of sheet iron, together with the improvements
described in ornamenting the same; and also in ornamenting the ordinary.
description of articles of the same kind which are made of cast or sheet
brass, or both combined, by japanning by any of the well-known japanning
processes, enamelling, painting, or inlaying them, as herein more fully set
forth and specified.
In witness whereof, I, the said Tertius John Cooke, have hereunto set my
hand and seal, this Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and fifty-seven.
