Year: 1874

page_text: LETTERS PATENT to George Edward Else, of Horsforth, in the
County of York, Mechanical Engineer, for the Invention of "Im-
PROVEMENTS IN VALVES OR Cocks."
Sealed the 22nd January 1875, and dated the 5th August 1874.
.
PROVISIONAL SPECIFICATION left by the said George Edward Else
at the Office of the Commissioners of Patents, with his Petition,
on the 5th August 1874.
I, GEORGE EDWARD ELSE, of Horsforth, in the County of York,
Mechanical Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN VALVES OR COCKS," to be as follows
My Invention relates to an improvement in the construction of valves
or cocks for steam, gas, water, or other fluid, wherein valves or cocks
are employed for closing and opening passages or ways for the exclusion
and admission of such fluids alternately.
This improvement consists in a plate of the shape shown in the
annexed Drawing; which is made in the manner and by the means

page_text: shown in the said Drawing to close the passage way through the valve
or cock, or to ascend into a chamber above, leaving the said passage way
clear of all obstruction, and of the same undiminished area as that of
the pipe itself for the direct inlet or outlet of the steam, water, gas, or
other fluid, which may be conveyed to the said passage way by the said
pipe.
The annexed Drawing represents a transverse vertical section of the
valvo or cock.
a, a, is the plate adjustable by the screwed stem a¹; b, b, are two
guides formed in the shell of the valve or cock, in which two wings c, c, 1
cast on the sides of the plate a are received to keep the plate always
in the same vertical position; d, d, is the chamber, into which the
said plate is made to ascend to open the passage way p
of the valve or
cock.
I obtain the perfect closing of the valve or cock by accurately fitting 1
those surfaces of the said plate which are necessary for such closing
against their seats, or by fixing on to them cork, leather, india-rubber,
felt, or other suitable material, as shown at x, x.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Edward Else in the Great Seal Patent ?
Office on the 26th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
EDWARD ELSE, of Horsforth, in the County of York, Mechanical
Engineer, send greeting. .
WHEREAS Her most Excellent Majesty Queen Victoria, 'by Her
Letters Patent, bearing date the Fifth day of August, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Edward Else, Her special licence
that I, the said George Edward Else, my executors, administrators,
and assigns, or such others as I, the said George Edward Else, my
executors, administrators, and assigns, should at any time agree with,

page_text: 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 VALVES OR COCKS," upon the condition (amongst others)
that I, the said Georgo Edward Else, 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 George Edward Elso, 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, reference being had to the accompanying
Drawing making part of this Specification, that is to say :-
My Invention consists in improvements in valves or cocks for steam,
water, gas, or other fluid having a valve plate, which, as shown in the
Drawing, is made to close the passage way through the valve or cock by
being screwed or pressed down upon its seats, and to open tho said
passage way by being screwed or raised up into a chamber above in the
shell of the valve or cock, leaving the said passage way straight and
clear of all obstruction, and of the same undiminished area as that of
the pipes on to which the valve or cock may be fixed.
The seats of the valvo or cock are made of soft metal, cork, vulcanised
india-rubber, felt, or other suitable material.
The form of the valve shell is, as shown in the Drawing, mado to
correspond with and adapted to the form of the valve plate.
It will be seen by reference to the Drawing that there is no friction
whatever by the valve plate in closing or opening.
In order that my said Invention may be fully understood and readily
performed, I refer to the annexed Drawing, which I will now procced
to describe.
Figure 1 is a longitudinal vertical section of the valve or cock through

page_text: The soft metal, cork, or other material may if preferred be run or fixed
in grooves made in the closing parts of the valve plate.
As shewn in the Drawing there are the usual fly wheel, spindle,
stuffing box, etc., for the working of the valve or cock.
Having particularly described and ascertained the nature of my
Invention, and in what manner the same is to be performed, I declare
that what I claim is, a valve plate, as shewn in the annexed Drawing,
which is screwed or pressed down upon its seats to close the passage
way of the valve or cock in combination with such parts of the valve
shell as must indispensably be made to correspond with and be adapted
to the form of the valve plate, and the valve shell cast with grooves,
in which either soft metal is run, or cork, vulcanised india-rubber,
felt, or other suitable material is fixed, so as to form seats at the
requisite places, arranged and operating substantially as herein-beforo
described.
In witness whereof, I, the said George Edward Else, have here-
unto set my hand and seal, this Twenty-third day of January, in
the year of our Lord One thousand eight hundred and seventy-
five.
