A NEW OR IMPROVED MODE OF SOLDERING TIN BOXES, CANISTERS, OR CASES
Year: 1868

page_text: LETTERS PATENT to Baldwin Fulford Weatherdon, of Law Chambers,
Chancery Lane, in the County of Middlesex, for the Invention of
"A NEW OR IMPROVED MODE OF SOLDERING TIN BOXES, CANISTERS, OR
CASES." A communication from abroad by Edouard Cormier, of
No. 10, Avenue Trudaine, Paris, in the Empire of France.
PROVISIONAL SPECIFICATION left by the said Baldwin Fulford.:
Weatherdon at the Office of the Commissioners of Patents, with his
Petition, on the 30th April 1868.
I, BALDWIN FULFORD WEATHERDON, of Law Chambers, Chancery
Lane, in the County of Middlesex, do hereby declare the nature of the
said Invention for "A NEW OR IMPROVED MODE OF SOLDERING TIN BOXES,
CANISTERS, OR CASES," (a communication from abroad by Edouard Cormier,:
of No. 10, Avenue Trudaine, Paris, in the Empire of France,) to be as
follows (that is to say) :-
This Invention relates to a new or improved mode of soldering tin
boxes, canisters, or cases of the ordinary descriptions for containing food
or other preparations, and consists in using "for the above purpose" the:

page_text: direct action of flame obtained from common gas, hydrocarbonaceous
and other inflammable matters in the form of a jet in combination with
a current of air, or oxygen gas supplied from a reservoir through the
medium of a blast fan or bellows in such manner as to admit of the said
jet of gas, together with the air or oxygen aforesaid being brought to
act upon a circular or other formed strip of solder, and by melting it
thus unite the parts to be joined. By this method the said packing cases
or boxes are enabled to be internally soldered from the outside thereof,
which by the ordinary method is impracticable; to facilitate the above
process a revolving platform or stand may be employed for holding the
canisters or otherwise, and thereby cause the operation of soldering to be
more expeditiously and effectually performed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said. Baldwin Fulford Weatherdon in the Great. Seal
Patent Office on the 29th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BALDWIN
FULFORD WEATHERDON, of Law Chambers, Chancery Lane, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth 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 Baldwin Fulford Weatherdon, Her special
licence that I, the said Baldwin Fulford Weatherdon, my executors,
administrators, and assigns, or such others as. I, the said Baldwin Fulford
Weatherdon, 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 "A NEW OR IMPROVED MODE OF SOLDERING TIN BOXES, CANISTERS, OR
CASES," (a communication to him from abroad by Edouard Cormier, of
No. 10, Avenue Trudaine, Paris, in the Empire of France,) upon the
condition (amongst others) that I, the said Baldwin Fulford Weatherdon,
my executors or administrators, by an instrument in writing under my,"

page_text: 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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Baldwin Fulford Weatherdon, 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):
:-
This Invention relates to an improved mode of soldering tin boxes,
canisters, or cases suitable for containing food or other preparations, and
consists in employing for the above purpose the direct action of the
flame of common gas or other hydrocarbonaceous or inflammable matters
in the form of a jet in combination with air or oxygen gas supplied from
a reservoir through the medium of a blast fan or bellows in such manner
as to admit of the said flame being brought in contact with a ring or
strip of solder, and by melting it thus unite the parts to be joined by
the running or fusion of the solder between the seams, by which
operation the said tins, boxes, or otherwise, as aforesaid, may be
internally soldered from the outside thereof, without the trouble and
inconvenience of a soldering iron, as hitherto employed.
And in order that this said Invention may be more fully understood
and readily carried into effect, I now proceed to describe in detail the
mode of performing the same (that is to say) :-
To facilitate the operation of soldering in accordance with my
improvements a table or platform is employed, upon which the tins
or cases for being soldered are placed so as to allow the jet of flame to
be brought more conveniently and closely in contact with the parts to be
united by giving to the said tins, cases, or otherwise the necessary lateral.
or longitudinal movement within the radius of the jet, which method may
also be readily applied to locked or unlocked boxes whilst submitting
them to the soldering process, either when already containing the
preserved food or in any or all of the various forms, descriptions, or
denominations known or in use for the above purposes.
In conclusion to the foregoing description I would here briefly note
that in the place of the revolving platform before referred to, a table
having a reciprocating motion may be substituted in all cases in which

page_text: a backward or forward movement is required for directing the flame
upon the solder longitudinally, with the seam or joint to be closed.
Having now fully described and ascertained the nature of this said
Invention, and the manner in which the same is to be performed and
carried into effect, I would have it clearly understood that I do not intend
to confine myself to the precise details of the process and the apparatus
herein-before described, as the same may be otherwise varied without
departing from the general principle of this said Invention, nor do I
claim as new and of my said Invention the several substances and
processes hercin-before set forth, except when the same are employed in
and for the purposes of this said Invention, which I hereby declare to
consist in the employment of ignited gas or other flame in the form of
a jet for soldering purposes, in conjunction with the revolving or reci-
procating platform, as herein-before set forth and described.
In witness whereof, I, the said Baldwin Fulford Weatherdon,
have hereunto set my hand and seal, this Twenty-second day of
October, in the year of our Lord One thousand eight hundred and
sixty-eight.
B. F. WEATHERDON. (L.S.)
Witness,
T. M. CORNOCK,
Clerk to Messrs. Weatherdon & Co.,
