"
Sealed the 1st May 1874, and dated the 12th March 1874.
PROVISIONAL SPECIFICATION left by the said Hugh Daniel Bayley
and George Henry Bayley at the Office of the Commissioners of
Patents, with their Petition, on the 12th March 1874.
We, HUGH DANIEL BAYLEY and GEORGE HENRY BAYLEY, both of
Leck, in the County of Stafford, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF TAPS OR VALVES,
WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO THE FIXING OF GLASS TUBES IN
WATER GAUGES," to be as follows:-
This Invention is applicable to all kinds of taps or valves having a
spindle passing out through a gland, such as taps or valves for steam,
gas, water, or oil, water gauges, tallow or oil cups, injectors, and spindle
valves of all descriptions, and is also applicable for fixing the glass tubes -

page_text: in water gauges, the object of the Invention being to make the spindle
steam, gas, or water-tight without the use of packing.
We employ a double valve with two ground surfaces, one working on
the ordinary seat, and the other reversed and working against a seat in
the gland through which the spindle passes, so that when the valve is
opened the second or reversed ground surface closes the joint between
the gland and the valve spindle. The valve spindle is provided with a
left-hand screw thread working in a similar tlircad tapped into a hollow
spindle or neck passing outwards through the gland, and having a small
hand wheel or lever. fitted on to its outer squared_end. A portion of the
valve spindle is squared and it is provented from turning by means of a
screw or pin.
The hollow spindle or neck is provided with a conical shoulder, is
ground to fit into the gland, through which it passes a nut, which is
screwed on to the outer end of the hollow spindle, and fixes the hand
wheel on to the square, serving at the same time to keep the conical
shoulders in close contact so as to form a perfectly tight joint.
It will be evident that as this hollow screwed spindle or neck is
turned round by the hand wheel the valve being prevented from turning
also will be caused to move in a longitudinal direction by means of its
externally screwed spindle working inside the hollow screwed spindle
aforesaid, and thus the valve will be opened or closed according to the
direction in which the hand wheel is turned, at the same time that the
ground conical surfaces and neck entirely prevent any escape of water or
other fluid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hugh Danicl Bayley and George Henry Bayley in
the Great Seal Patent Office on the 11th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, HUGH
DANIEL BAYLEY and GEORGE HENRY BAYLEY, both of Leck, in the 30
County of Stafford, send greeting.

thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Hugh Daniel Bayley and
George Henry Bayley, Her special license that we, the said Hugh
Daniel Bayley and George Henry Bayley, our executors, administrators,
and assigns, or such others as we, the said Hugh Daniel Bayley and
George Henry Bayley, our executors, administrators, and assigns, should
at any time agree with and no others, from time to time and at all
times thercafter 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 CONSTRUCTION OF TAPS OR VALVES, WHICH
IMPROVEMENTS ARE ALSO APPLICABLE TO THE FIXING OF GLASS TUBES IN WATER
GAUGES," upon the condition (amongst others) that we, the said Hugh
Daniel Bayley and George Henry Bayley, our executors or admini-
strators, by an instrument in writing under our, or one of our 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Hugh Daniel Bayley, on behalf of
myself and the said George Henry Bayley, 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, and accompanying Drawings (that is to say) :—
This Invention is applicable to all kinds of taps or valves having a
spindle passing out through a gland, such as taps or valves for steam,
gas, water, or oil, water gauges, tallow or oil cups, injectors, and spindle
valves of all descriptions, and is also applicable for fixing the glass tubes
in water gauges, the object of the Invention being to make the spindle.
steam, gas, or water-tight without the use of packing..
Such being the nature and object of the said Invention, in order that.
the same may be more clearly understood, we have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with.
figures and letters of reference corresponding with those in the following
explanation thereof :-
.
In the annexed Drawing Fio: 1, is an external elevation: and Fire 2

page_text: a section of a steam tap made according to our Invention; and Figs. 3
and 4 are sections showing the application of the same to a water gauge;
Fig. 3 being a section through the line A, B, in Fig. 4, which latter is a
section through the line C, D, in Fig. 3. These we have shown as being
sufficient for the purpose of illustrating our Invention, and we would here.
repeat that our Invention is applicable to all kinds of taps or valves which
have a spindle passing out, which requires to be made steam, gas, or
water-tight, the modifications of our Invention to adapt it to different;
forms of taps or valves being so obvious as not to require further
description.
We employ (by preference) a double valve a (see Fig. 3, with two
ground surfaces b, b', one working on the ordinary seat c, c, and the
other reversed and working against a seat d, d, in the gland e, e, through
which the spindle passes, so that when the valve is opened the second or
reversed ground surface b' closes the joint between the gland e and the 1
valve spindle ff. The valve spindle f, f, is provided with a left-hand
screw thread g, g, working in a similar thread tapped into a hollow
spindle or neck h, h, passing outwards through the gland e, e, having a
small hand wheel i, i, or lever fitted on to its outer squared end. A
portion of the valve spindle is squared and it is prevented from turning 2
by means of a screw or pin k, k.
:
.
The hollow spindle or neck h, h, is provided with a conical shoulder 1, 1,
which is ground to fit into the gland through which it passes; a.
nut'm, 'm, which is screwed on to the outer end of the hollow spindle
and fixes the hand wheel on to the square, serving at the same time to 2
keep the conical shoulder 1, 1, in close contact so as to form a perfectly
tight joint.
It will be evident that as this hollow screwed spindle or neck h, h, is
turned round by the hand wheel i, i, the valve a being prevented from.
turning also will be caused to move in a longitudinal direction by means a
of its externally screwed spindle g working inside the hollow screwed
spindle aforesaid, and thus the valve a will be opened or closed accordingly
to the direction in which the hand wheel i, i, is turned, at the same time
that the ground conical surface 1, 1, and neck h, h, entirely prevent any
escape of water or other fluid.' ·
Fig. 4 shows the application of our Invention to the fixing of the
glass tube in a water gauge which will be readily understood from the

page_text: foregoing description, as the same letters of reference are placed upon
the corresponding parts'; n, n, being india-rubber washers, and o, o, the
glass tube.
Fig. 2 represents a steam tap; p, p, being the body of the tap. In
this modification it will be perceived that the second conical surface on
the valve is dispensed with, and that the valve spindle f. f, is made
hollow instead of the neck h, h, which latter is in this case made in the
form of a spindle having at one end a screw g, g, which works in the
screwed recess of the hollow valve spindle f, f.
Having now described the nature and object of our said Invention,
together with the manner in which the same is to be or may be
performed or carried into practical effect, we wish it to be understood
that we claim as our Invention, the combination with the valve a
of the screw g and neck h with its conical ground shoulder or surface
for the purpose of keeping the spindle steam, gas, or water-tight,
whether the screw 9 is formed on the valve spindle and works in a hollow
screwed neck, or whether the screw is formed on the neck and works
in a hollow screwed valve spindle, all constructed and working sub-
stantially as herein-before described and illustrated by the Drawings
annexed.
In witness whereof, I, the said Hugh Daniel Bayley (on behalf of
myself and the said George Henry Bayley), have hereunto set.
my hand and seal, this Seventh day of September, in the
year of our Lord One thousand eight hundred and seventy-
four.
