Year: 1856

page_text: LETTERS PATENT to John Taylor, of Hackney Road, in the County of
Middlesex, for the Invention of "AN IMPROVED VESSEL FOR CONTAINING
CHEMICALS FOR THE GENERATION OF DISINFECTING GASES."
aled the 22nd August 1856, and dated the 24th June 1856.
PROVISIONAL SPECIFICATION left by the said John Taylor at the Office
of the Commissioners of Patents, with his Petition, on the 24th June
1856.
I, JOHN TAYLOR, of Hackney Road, in the County of Middlesex, do hereby
declare the nature of the said Invention for "AN IMPROVED VESSEL FOR
CONTAINING CHEMICALS FOR THE GENERATION OF DISINFECTING GASES," to be as
follows:-
The object of this Invention is to provide a vessel capable of containing
chemicals for the generation of disinfecting gases, which, when desired, may be
readily and securely closed to prevent the escape of the gaseous products.
This is effected by fixing above the mouth or orifice of a vertical vessel of
glass or earthenware, for containing the chemicals, a cross bar of wood or other
non-corrosive substance; the cover of the vessel, having attached to its under
side a ring of vulcanized india-rubber, is fixed to a screw which works through
a nut formed in the before-mentioned cross bar over the centre of the mouth
or orifice. By the action of the screw the cover attached to it may be
depressed so as to compress forcibly the india-rubber ring between the cover
and the margin around the orifice of the vessel, and effectually to close the
latter. By the contrary action it may be as readily opened to permit the
confined gases to escape.

by the said John Taylor in the Great Seal Patent Office on the 20th

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TAYLOR, of Hackney Road, in the County of Middlesex, send greeting.
WHEREAS 1ler most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of June, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said John Taylor, Her special licence that I, the said John Taylor, my
executors, administrators, and assigns, or such others as I, the said John
Taylor, 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 "AN IMPROVED VESSEL FOR CON-
TAINING CHEMICALS FOR THE GENERATION OF DISINFECTING GASES," upon the
condition (amongst others) that I, the said John Taylor, 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Taylor, 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 state-
ment:-
The object of this Invention is to provide a vessel capable of containing
chemicals for the generation of disinfecting gases, which, when desired, may be
readily and securely closed to prevent the escape of the gaseous products. This
is effected by fixing above the mouth or orifice of a vertical vessel of glass or
earthenware, for containing the chemicals, a cross bar of wood or other non-
corrosive substance; the cover of the vessel, having attached to its under
side a ring of vulcanized india-rubber, is fixed to a screw which works through
a nut formed in the before-mentioned cross bar over the centre of the orifice 3
or month. By the action of the screw the cover attached to it may be
depressed, so, as to compress forcibly the india-rubber ring between the cover
and the margin around the orifice of the vessel, and effectually to close the

page_text: latter. By the contrary action it may be as readily opened to permit the con-
fined gases to escape.
DESCRIPTION OF THE DRAWINGS.
Having thus described the nature of my said Invention, I will now proceed
to explain more fully and with reference to the various Figures of the accom-
panying Drawing, several modes by which the same may be carried into
effect.
Fig. 1 is a vertical section of a vessel for containing chemicals as de-
scribed, and Fig. 2, a side elevation of the same; a, represents the vessel
(which I prefer to form of glass or earthenware), above the mouth or orifice of
which is fixed the cross bar b, formed of wood, and supported by the framing c.
The screw works through a nut formed in the cross bar b, and at its lower
end carries, but is left free to revolve within, the socket e, to which it is attached
by means of the nut f. The socket fits upon a central projecting portion of
the cover g, and is attached thereto by means of pins which take into a groove
or into suitable holes formed in the before-named central projection. To the
under side of the cover g is attached a ring of vulcanized india-rubber h,
which when the cover is depressed by the action of the screw d, becomes
forcibly compressed between the cover g, and the margin around the orifice of
the vessel, thereby forming a perfectly air-tight and secure joint. It will be
obvious, on reference to the Drawings, that by a contrary movement of the
screw d the cover 9 may be raised so as to permit the confined gases to escape.
Fig. 3 is a front elevation, partly in section, and Fig. 4 a side elevation, of a
vessel for the same purpose, having the cross bar b attached thereto by means
of the vertical bars or framing c. In these Figures the end of the screw is
fitted with a ring i, in which it is free to revolve; this ring is secured to the
screw by means of the nut k, and fits into a suitable cavity formed to receive
it in the cover g, wherein it is secured by pins as shewn. Figs. 5 & 6.
are corresponding views of a similar vessel, having the cross bar b formed in
one piece therewith, and fitted with a nut of wood or other suitable material
for the screw d to work through.
In witness whereof, I, the said John Taylor, have hereto set my Land
