01.1
PROVISIONAL SPECIFICATION left by the said William Henry Tayler
at the Office of the Commissioners of Patents, with his Petition, on the
16th July 1855.
*.
I, WILLIAM HENRY TAYLER, of 19, South Row, New Road, St. Pancras,
5 Middlesex, London, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HERMETICALLY SEALING PRESERVE CANISTERS AND OTHER VESSELS
BY MEANS OF A NEW-- ARRANGED SCREW CAP & FITTINGS" to be as follows:-
Bylapplying to the top of canister or vessel a screw cap, whose inner angle
being lined with a gasket of vulcanized india-rubber or other material, &
which; on the screwing down of the cap or cover, becomes pinched between
the under surface thereof & the rim of the raised neck of canister, which
neck is screw threaded on its convex side to fit a concave screw within the
cover. Immediately outside of and surrounding the neck is a. trough, formed
by a small flange projecting upwards from the top of the can or vessel. The
Dmine

page_text: cover being screwed down to its place, bees-wax or suitable mixture is poured
into the trough, so as to rise above and effectually close over the joint between
the neck & lower edge of the cover, & the can or vessel is then permanently
sealed.
For preserving, on the top of the screw cap there is a small adjusting screw
to shut off the steam immediately the process is completed. The cap is
screwed down by a lever, and as the soldering iron is dispensed with, these
canisters or vessels may be made available for preserving powder and other
inflamable material. For domestic purposes, it will greatly increase the
facility for preserving provisions.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Tayler, in the Great Seal Patent Office on the
12th December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL. COME, I, WILLIAM
HENRY TAYLER, of 19, South Row, New Road, Saint Pancras, Middlesex,
London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of July, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Henry Tayler, Her special licence that I, the said William Henry
Tayler, my executors, administrators, and assigns, or such others as I, the
said William Henry Tayler, 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 "IMPROVE
MENTS IN HERMETICALLY SEALING PRESERVE CANISTERS AND OTHER VESSELS BY
MEANS OF A NEW ARRANGED SCREW CAP AND FITTINGS," (a communication,) upon
the condition (amongst others) that I, the said William Henry Tayler, by
an instrumentin 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,

page_text: NOW KNOW YE, that I, the said William Henry Tayler, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof (that is to say):-
same.
Figure 1 represents the said Invention in elevation, and Figure 2 represents
the same in vertical section; and Figure 3 represents a plan of the top of the
a is a cylindrical or other shaped vessel, the neck of which has a
screw thread c made on its exterior; d is a cap or cover, the interior of which
is furnished with a concave screw, corresponding to the convex screw on the
exterior of the neck 6; c is a gasket washer,or ring of vulcanized caoutchouc
or other elastic material, which lines the top of the cap d, and which, when
the said cap is screwed on the neck b, as represented in Figures 1 and 2, is
compressed between the top of the cap and top of the neck b; fis an
annular trough, situated at the bottom of the neck b, into which said trough
the lower edge of the cap d enters, when screwed in its place on the neck b,
as represented; g is an opening on the top of the cap d, which said opening
may be closed at pleasure by the screw cap hand washeri of vulcanized caout-
chouc; k, k, are pins or studs on the top of the cap 7. In screwing down the
cap d,the key or lever, Figure 4, is placed upon the cap d, so that the pins or
studs kc, k, may pass through and engage in the holes in the key or lever,
Figure 1; by turning the said key or lever, Figure 4, the said cap d may
be screwed down with the requisite degree of tightness. In using the said
Invention as a preserve canister, the vessel a is filled with the matter to be
preserved; the cap d with the small cap is then screwed upon the neck b,the
said cap being screwed tightly by means of the key or lever, Figure 4. A
small quantity of water is put in the vessel a,and the said vessel a is heated in
a water bath or otherwise. When the vessel a has been sufficiently heated,
which will depend upon the nature of the matters contained therein, as is
well understood by cooks and others engaged in the preservation of articles of
food, the cap h is unscrewed, and immediately the steam has blown off, the
said cup
is again screwed tightly upon the opening g, and the washer i closes
the said opening. The vessel a is now removed from the source of heat, and
bees-wax, or other cement easily liquified by heat, is placed in the trough f;
the said bees-wax or cement fuses by the heat of the neck b. If the said
cement be applied on the removal of the vessel a from the source of heat, or
if the said cement be applied after the vessel a has cooled, it must be fused by
the application of a hot iron, or in any other convenient manner. When the
cement which has been fused in the annular trough has cooled, the
cap dis
hermetically sealed upon the neck b,and the vessel a is as effectually closed as

page_text: if the opening were soldered up. TheInvention herein described and illustrated
in the accompanying Drawing, may be used for preserving powder and other
inflammable materials.
Having now described the nature of the said Invention, and the manner
of carrying the same into effect, I wish it to be understood that I do not
limit myself to the precise details herein described, as the same may be varied
without departing from the nature of the said Inventiou; but I claim as the
said Invention, the method herein described, and illustrated in the accompany-
ing Drawing, of hermetically sealing or closing preserve canisters and other
vessels, that is to say, by the use of a screw cap or cover provided with a
gasket or washer of vulcanized caoutchouc or other elastic material, the lower
edge of the said screw cap or cover entering an annular trough containing
cement, which cement, after being fused and allowed to cool, hermetically seals
the screw cap or cover upon the canister or vessel.
In witness whereof, I, the said William Henry Tayler, have hereunto
set my hand and seal, this Twelfth day of December, in the year of
our Lord One thousand eight hundred and fifty-five.
Witness,
JAMES MURDOCH.
W. H. TAYLER. (L.s.)
