Year: 1875

page_text: LETTERS PATENT to Matthew John Hart, of Thirty-six, Great Barr
Street, in the Borough of Birmingham, in the County of Warwick,
Manufacturer of Tin Plate Ware, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF HANDLES FOR TEAPOTS AND OTHER LIKE
· PURPOSES."
Sealed the 6th October 1875, and dated the 4th May 1875.
PROVISIONAL SPECIFICATION left by the said Matthew John Hart
at the Office of the Commissioners of Patents, with his Petition,
on the 4th May 1875.
I, MATTHEW JOHN HART, of Thirty-six, Great Barr Street, in the
5 Borough of Birmingham, in the County of Warwick, Manufacturer of
Tin Plate Ware, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF HANDLES FOR TEAPOTS AND OTHER LIKE
PURPOSES," to be as follows:-

:-
The object of my Invention is to ensure a stronger and more sightly
attachment of cast metal handles to teapots and other similar vessels.
By means of suitable raising punches and dies I raise metal cups or
thimbles from tin plate or other sheet metal. Through the centre of the

page_text: bottom of each such cup or thimble I pierce a hole, and fasten through
the said hole a tinned rivet, placing the head of the said rivet within
the cup or thimble close to the bottom of the said cup or thimble so
that the shank of the said rivet projects through the bottom of the said
cup or thimble outwards. In casting the handle I place the cups or
thimbles so prepared in the mould so that the fluid metal when run in
sets around the said rivet shanks and close up to the bottom of each of
the said cups or thimbles. The cups or thimbles are thus firmly united to
the ends of the handle in positions suited for the subsequent operation
of soldering the said cups or thimbles to the teapot or other like vessel,
the open end of each cup or thimble being soldered to the said vessel.
To ensure firm attachment of the cast metal to the before-mentioned
rivet shanks I screw the said shanks with an ordinary thread or stamp
them between dies of such form as to jag them at right angles to their
length.
In some cases I use the before-described cups or thimbles without the
addition of rivets, and in these cases I punch out the whole or nearly
the whole of the bottom of cach such cup or thimble, and cause the cast
metal of the handle to run around or into and partly fill the said cup or
thimble.
According to another mode of carrying out my improvements I cut
drawn tubes into suitable lengths to form seamless ferules, into which I
cast the handles, as before described. The ferules so cut from drawn
tubes I prefer to spin or stamp to the proper tapered form before
casting the handles into them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew John Hart in the Great Seal Patent
Office on the 4th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATTHEW
JOHN HART, of 36, Great Barr Street, in the Borough of Birmingham, a
in the County of Warwick, Manufacturer of Tin Plate Ware, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters. Patent, bearing date the Fourth day of May, in the year of our

page_text: Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Matthew John Hart, Her special licence
that I, the said Matthew John Hart, my executors, administrators, and
assigns, or such others as I, the said Matthew John Hart, 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 MANUFACTURE OF HANDLES FOR TEAPOTS ANd other like PuRPOSES," upon
the condition (amongst others) that I, the said Matthew John Hart,
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 next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Matthew John Hart, 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:-
The object of my Invention is to ensure a stronger and more sightly
attachment of cast metal handles to teapots and other similar vessels.
By means of suitable raising punches and dies I raise metal cups or
thimbles from tin plate or other sheet metal. Through the centre of
the bottom of each such cup or thimble I pierce a hole, and fasten
through the said hole a tinned rivet, placing the head of the said rivet
within the cup or thimble close to the bottom of the said cup or thimble,
so that the shank of the said rivet projects through the bottom of the said
cup or thimble outwards. In casting the handle I place the cups or
thimbles so prepared in the mould, so that the fluid metal when run in
sets around the said rivet shanks and close up to the bottom of each of
the said cups or thimbles; the cups or thimbles are thus firmly united
to the ends of the handle in positions suited for the subsequent operation
of soldering the said cups or thimbles to the teapot or other like vessel,
the open end of each cup or thimble being soldered to the said vessel.

page_text: To ensure firm attachment of the cast metal to the before-mentioned
rivet shanks I screw the said shanks with an ordinary thread, or stamp
them between dies of such form as to jag them at right angles to their
length.
In some cases I use the before described cups or thimbles without the
addition of rivets, and in these cases I punch out the whole or nearly
the whole of the bottom of each such cup or thimble, and cause the cast
metal of the handle to run around or into and partly fill the said cup or
thimble.
According to another mode of carrying out my improvements I cut
down tubes into suitable lengths to form seamless ferules, into which
I cast the handles, as before described. The ferules so cut from drawn
tubes I prefer to spin or stamp to the proper tapered form before casting
the handles into them.
Having thus described the nature and object of my said Invention,
and the manner in which the same is or may be carried into effect, I
declare that what I claim and desire to be secured to me by the herein-
before in part recited Letters Patent is, the improvements in the manu-
facture of handles for teapots and other like purposes for ensuring a
stronger and more sightly attachment of handles to teapots and other
similar vessels, substantially as herein-before described, or any mere
modification thereof.
In witness whereof, I, the said Matthew John Hart, have here-
unto set my hand and seal, this Third day of November, in the
year of our Lord One thousand eight hundred and seventy-
five.
