A NEW OR IMPROVED GAS VALVE AND PROVISIONAL SPECIFICATION
Year: 1880

page_text: LETTERS PATENT to Percy John Wates, of the Brooklands, Balham, in the
County of Surrey, Civil Engineer, and Samuel Chandler and Josiah Chandler,
both of 104, Newington Causeway, in the said County of Surrey, Gas
Engineers, for an Invention of "A NEW OR IMPROVED GAS VALVE AND
PROVISIONAL SPECIFICATION left by the said Percy John Wates, Samuel
Chandler, and Josiah Chandler at the Office of the Commissioners of
Patents on the 25th October 1880.

Civil Engineer, and SAMUEL CHANDLER and JOSIAH CHANDLER, both of 104,

IMPROVED GAS VALVE AND APPLIANCES CONNECTED THEREWITH.”
Our Invention has for its object improvements in gas apparatus, and consists of a
simple and inexpensive valve applied and connected to the upper part of the
ordinary dip casting, or it may be inade a part of the same casting and bolted to the
top of the hydraulic main, and so when open to provide an unobstructed passage
for the gas from the retort to the condensers, and when closed the gas would travel
through the ordinary dip pipe. The valve is constructed and formed as follows:-The
outer casing is of cast iron having two flanges cast on, one on the bottom
horizontal to the face of the valve, and that on the side vertical to the same.
the top of the valve is bolted a stuffing box, through which a rod passes, on the inner
extremity of which the face disc of the valve is fastened, and is opened and closed
against a projecting face by the aforesaid rod.
On
An important feature in this arrangement is the means we have devised for
cleaning the seating and face should any matter adhere to them which would tend
to make it unsound, and this consists of applying to the rod which passes through a
stuffing box (from the disc valve), a ring and lever, whereby the same may be
turned right round as often as desirable to clean the joints and render the apparatus
sound and workable.
The valve may be made so as to be actuated either from the floor of the retort
house or bed of retorts.
We have also devised a means of cleaning out the opening of the valve itself by
fixing on the front of the disc a projection, which will completely cut away any
obstruction to the flow of gas.
By permitting no pipe to intervene between the inside of dip and the inside of
hydraulic main it is most unlikely that any deposit or obstruction can arise.

Great Seal Patent Office on the 25th April 1881.

IMPROVED GAS VALVE AND APPLIANCES CONNECTED THEREWITH."
Our Invention has for its object improvements in gas apparatus, and consists of a
simple and inexpensive valve applied and connected to the upper part of the
ordinary dip casting, or it may be made a part of the same casting and bolted to
the top of the hydraulic main, and so when open to provide an unobstructed passage
to the gas from the retort to the condensers, and when closed the gas would travel
through the ordinary dip valve. The valve is constructed and formed as follows:-
The outer casing is of cast iron having two flanges cast, one on the bottom
horizontal to the face of the valve, and that on the side vertical to the same. On
the front of the valve is bolted, or it may be a part of the casting forming the
valve, a stuffing box, through which a rod passes, on the inner extremity of which
the face disc of the valve is fastened, and is opened and closed against a projecting
face or seat by the aforesaid rod.
An important feature in this arrangement is the means we have devised for
cleaning the seating and face should any matter adhere to them which would tend
to make it unsound, and this consists of applying to the rod which passes through a
stuffing box (from the disc valve), a ring, and lever, whereby the same may be
turned right round as often as desirable to clean the joints and render the apparatus
sound and workable.
The valve may be made so as to be actuated either from the floor of the retort
house or bed of retorts.
We have also devised a means of cleaning out the opening of the valve itself by
fixing on the front of the disc a projection, which will completely cut away any
obstruction to the flow of gas.
By permitting no pipe to intervene between the inside of dip and the inside of
hydraulic main it is most unlikely that any deposit or obstruction can arise.
And in order to make the Invention better understood, we now make reference to
the accompanying Drawings.
Figure 1, side elevation of valve, with section of hydraulic main.
Figure 2, front elevation of valve, with section of hydraulic main.
Figure 3, sectional elevation of valve, with section of hydraulic main.
Figure 4, sectional plan.
Figures 5 and 6, plan and sectional elevation of different arrangements of the
valve.
The same letters apply to all the sketches.
The case of the valve itself is made in one casting and is fixed in the angle
between the dip pipe and the hydraulic main, a circular hole being cut in the dip,
and a rectangular one in the hydraulic main, and is fixed thereto by means of
bolts and flanges.
In Figures 1, 2, 3, and 4 the valve is fixed on the side of the dip nearest the
stage, and is actuated from below by a rod L, L, M, attached to a lever E, at the
opposite end of which a ball A keeps the valve open or shut just as it is placed on
one or other side of the centre W.
The link H is attached to a strap C, which rotates in a corresponding recess in
the valve case and permits the grinding on to its seat of the valve disc N.

page_text: The lever B and weight A are kept in the position shewn by a catch resting on a
lug J a little to the left of the centre.
In Figures 5 and 6 the valves is fixed on the opposite side of dip, and is opened
and closed by hand.
On the valvo disc N are two bevelled ears T, T, which, when the valve is closed, are
tightened into two corresponding recesses S, S.
Upon the face of the valve is cast a cleaner R, which removes every deposit from the
hole in the dip should any such be formed.
The cross bead U is left on one side of rod G only in order that its weight may hold
the valve tight against its seat.
Having now described the nature of our Invention, and the manner in which it is
actuated, we wish it to be understood that we do not limit ourselves to the exact
details herein before described, as the same may be varied without departing from
the nature of our said Invention, but what we do claim as our Invention is the
improved gas valve as described and set forth.
In witness whereof, I, the said Samuel Chandler, have hereunto set my hand
and seal, this Twenty second day of April, in the year of our Lord One
thousand eight hundred and eighty one.
