page_text: LETTERS PATENT to John Wilson, of Birmingham, in the County of
Warwick, Brass Founder, for the Invention of "CERTAIN IMPROVEMENTS.
IN THE MANUFACTURE OF KNOBS FOR DOORS, CUPBOARDS, ASH PANS, AND FOR
OTHER LIKE PURPOSES."
Sealed the 25th May 1866, and dated the 1st December 1865.
PROVISIONAL SPECIFICATION left by the said John Wilson at the Office
of the Commissioners of Patents, with his Petition, on the 1st December
1865.
I, JOHN WILSON, of Birmingham, in the County of Warwick, Brass Founder,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
HENTS IN THE MANUFACTURE OF KNOBS FOR DOORS, CUPBOARDS, ASH PANS, AND FOR
OTHER LIKE PURPOSES," to be as follows:-
Hitherto when it has been desired to produce a brass.knob it has been cast
in brass. The object of this Invention is by the means herein-after set forth
to produce a like article which for all practical purposes shall be as good
though it can be made at a very much lower cost. Instead. of casting the
knob in brass I cast it in iron, and then turn a brass shell over the front part

page_text: of the knob; this said shell must of course be exactly the size of the front
part of the knob, which it then exactly covers; afterwards I spread a bronze
coloring over the neck of that part of the knob not covered by the brass shell,
when the whole appears as though made of brass.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Wilson in the Great Seal Patent Office on the 1st
June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILSON, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Wilson, Her special licence that I, the said John Wilson,
my executors, administrators, and assigns, or such others as I, the said John
Wilson, 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 "CERTAIN IMPROVEMENTS IN THE
MANUFACTURE OF KNOBS FOR DOORS, CUPBOARDS, ASH PANS, AND FOR OTHER LIKE
PURPOSES," upon the condition (amongst others) that I, the said John Wilson,
my executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 John Wilson, 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):-
:-
Hitherto when it has been desired to produce a brass knob it has been
cast in brass. The object of this Invention is by the means berein-after set
forth to produce a like article which for all practical purposes shall be as

page_text: good, though it can be made at a very much lower cost. Instead of casting
the knob in brass I cast it in iron, and then turn a brass shell over the front
part of the knob. This said shell must of course be exactly the size of the
front part of the knob, which it then exactly covers. Afterwards I spread a
bronze coloring over the neck and that part of the knob not covered by the
brass shell, when the whole appears as though made of brass.
That my Invention may be better understood I have annexed Drawings
referring thereto, which I now proceed to describe :-
Fig. 1 is an elevation and part section of a common door-lock handle.
is the cast-iron knob; b is the brass shell turned over it; c is that part of the
knob covered with bronze. Fig. 2 is an elevation of a door handle; Fig. 3
is an elevation of a cupboard turn. Similar letters of reference refer to like
parts in the several Figs.
Having now described the nature of my said Invention, and the manner
in which the same is or may be performed, I desire it to be understood that -
without limiting myself strictly to the precise details herein-before described,
I desire to claim as the Invention to be protected by the herein-before in
part recited Letters Patent, the Invention for "Certain Improvements in the
Manufacture of Knobs for Doors, Cupboards, Ash Pans, and for other like
Purposes," substantially as herein-before set forth and shown in the Drawings
hereunto anuexed.
In witness whereof, I, the said John Wilson, have hereunto set my
band and seal, this Thirtieth day of May, in the year of our Lord
One thousand eight hundred and sixty-six.
