IMPROVE- MENTS IN BIRDCAGES
Year: 1868

page_text: LETTERS PATENT to Samuel Robotham, of Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "IMPROVE-
MENTS IN BIRDCAGES."
Sealed the 28th October 1868, and dated the 29th April 1868.
PROVISIONAL SPECIFICATION left by the said Samuel Robotham
at the Office of the Commissioners of Patents, with his Petition,
on the 29th April 1868.
I, SAMUEL ROBOTHAM, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BIRDCAGES," to be as follows:-
My improvements have reference in particular to one material
employed in constructing birdcages according to my Invention and to
the combination with other materials.
The principal material is "parksine," of which I form the bottom
(generally); this material "parksine" is the patented article of that
name, it being of such nature that when pressed into the form required
it is unaffected by water, acid, oil, or oxidation, not easily broken, and
of a clear smooth surface of various colours or mixtures thereof.

page_text: "
I form the bottom of a birdcage by pressing the material "parksine'
when plastic into a die, and by introducing the eyes or parts of
fastenings (to connect the top and bottom of a cage) at the time I save
rivetting, but I make them with or without these eyes or parts of
fastenings as required; the panels, fonts, or seed boxes and upright
frames I sometimes make of "parksine," and cover the metallic work
with electro deposit of metals or their alloys; I also electro deposit cages
when all metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Robotham in the Great Seal Patent Office
on the 29th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
ROBOTHAM, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of April, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Robotham, Her special licence
that I, the said Samuel Robotham, my executors, administrators, and
assigns, or such others as I, the said Samuel Robotham, my executors,
administators, 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 BIRDCAGES,"
upon the condition (amongst others) that I, the said Samuel Robotham,
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 performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months ne and immediately
after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Samuel Robotham, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
My improvements have reference in particular to one material
employed in constructing birdcages according to my Invention and to
the combination thereof with other materials.
The principal material is "parksine," of which I form the bottom
(generally); this material "parksine" is the patented article of that
name, it being of such nature when pressed into the form required is
unaffected by water, acid, oil, or oxidation, not easily broken, and of a
clear smooth surface of various colours or mixture thereof.
I form the bottom of a birdcage by pressing the material "parksine"
when plastic into a die, and by introducing the eyes or parts of
fastenings (to connect the top and bottom of a cage) at the time I
save rivetting, but I make them with or without these eyes or parts of
fastenings as required; the panels, fonts, or seed boxes or upright frames
I sometimes make of "parksine," and cover the metallic work with electro
deposit of metals or their alloys; I also electro deposit cages when all
metal.
Having now described the nature of my Invention, and the manner of
performing the same, I declare that I do not confine myself to any
particular mode of manufacture; but what I claim is, the manufacture of
birdcages of parksine in combination with other suitable materials; also
the manufacture of birdcages of metal or partly of metal, and coating
the said metallic parts by electro deposit.
In witness whereof, I, the said Samuel Robotham, have here-
unto set my hand and seal, this Twenty-second day of October,
in the year of our Lord One thousand eight hundred and sixty-
eight.
SAMUEL ROBOTHAM. (L.S.)
