Old Kent Road, in the County of Surrey for an Invention of "IMPROVEMENTS
IN APPARATIIS TIRED TN

PROVISIONAL SPECIFICATION left by the said John Somerville at the
Office of the Commissioners of Patents on the 20th October 1883.
JOHN SOMERVILLE of the South Metropolitan Gas Works, Old Kent Road, in the
County of Surrey "IMPROVEMENTS IN APPARATUS USED IN THE MANUFACTURE
OF GAS,"
$
This invention may be applied to apparatus used for different purposes in the
manufacture of gas, but is specially adapted for use in connection with the dip-pipes
and hydraulic main, and in the construction of washers; the object being in
combining it with the dip-pipe to greatly relieve the retort from the pressure of gas
when the coal is being distilled, and at the same time affording an effective seal to
the dip-pipe when gas is not flowing through it, and when used in the construction
of washers to ensure the more thorough washing of the gas, and to reduce the
pressure such washing frequently produces.
The invention with regard to dip-pipes consists in either casting on, or attaching
to the lower part of the dip pipe a somewhat funnel shaped cup, dipping into the
liquid in the hydraulic and having a hole at its bottom, proportionate to the
diameter of the dip-pipe. The effeciency of the apparatus depends very much upon
the size of this hole which is found should be for a five inch dip, about one inch
more or less in diameter.
The invention with respect to washers consists in the insertion, in each chamber
of the washer, of a number of short tubes, say of one and a quarter inch diameter,
beneath the lower part of each of which is arranged a somewhat funnel shaped cup,
similar to that described as applied to the dip-pipe, and having a hole about a
quarter of an inch more or less in diameter at the bottom.
The action of the apparatus as applied to dip-pipes and washers is the same, for
as the gas passes down the dip or short tube the pressure it exerts on the surface
of the liquid with which the hydraulic or washer is charged, drives the liquid up
the sides of the cup in the form of small bubbles, or spray, and as but little
pressure is sufficient to produce this effect the gas gets away readily from the dip,
and the short tube, while in the case of the washer from the constant supply of
liquid to the cups through the small orifices in the bottoms of them, the gas is
effeciently washed.

JOHN SOMERVILLE of the South Metropolitan Gas Works, Old Kent Road, in the
County of Surrey "IMPROVEMENTS IN APPARATUS USED IN THE MANUFACTURE
OF GAS"
This invention may be applied to apparatus used for different purposes in the
manufacture of gas, but is specially adapted for use in connection with the dip-pipes
and hydraulic main, and in the construction of washers, the object being in
combining it with the dip-pipe greatly relieve the retort from pressure of gas
when the coal is being distilled, and at the same time affording an effective seal to
the dip-pipe when gas is not flowing through it, and when used in the construction
of washers to ensure the more thorough washing of the gas, and to reduce the
pressure such washing frequently produces.
The invention with regard to dip-pipes consists in either casting on, or attaching
to the lower part of the dip-pipe a somewhat funnel shaped cup dipping into the
liquid in the hydraulic and having a hole at its bottom proportionate to the
diameter of the dip-pipe. The efficiency of the apparatus depends very much upon
the size of this hole which is found should be for a five inch dip, about one inch
more or less in diameter.
The invention with respect to washers consists in the insertion in each chamber
of the washer of a number of short tubes, say of one and a quarter inch diameter,
beneath the lower part of each of which is arranged a somewhat funnel shaped cup,
similar to that described as applied to the dip pipe, and having a hole about a
quarter of an inch more or less in diameter at the bottom.
In order that the foregoing may be more easily understood drawings are attached
hereto of which the following is a description. Fig 1 is an elevation of part of the
dip-pipe, the hydrawlic main being, partly in section as well as the funnel shaped
cup. Fig 2 is a sectional elevation of the dip-pipe, cup and hydraulic main and the
arrangement for adjusting the height of the liquid in, and carrying off the super-
fluous liquid from the hydraulic main.-Fig 3 is a plan of the dip-pipe and cup
through A B Fig 2.-Fig 4 is a plan of the washer with some of the top plates
removed in order to see the interior.-Fig 5 is in part an elevation and part
sectional elevation of the washer. Fig 6 is a plan of one of the tubes and cups and
Fig 7 a sectional elevation of the same, the two latter Figs being drawn full size.―
In each of the Figa similar letters represent the same parts-In Figs 1, 2 and 3, A
is the dip-pipe, B the cup supported by the strap C and curved rods D, D together
with the tightening screw E.-F is the hydraulic main and G is the tar and
overflow liquid receiver communication being made between it and the hydraulic
main by means of the pipes H and I.-J. J is the overflow pipe the height of which
is adjustable by screwing the collar K up or down.-In Figs 4, 5, 6 and 7 or some of
them L is the case of the washer which is divided into chambers by the vertical
partitions M M and horizontally by N N.-O is the gas inlet,-P P the tubes and
RR the cups. S S are conduits for conveying the gas from one chamber to another
and T the gas outlet.-U is the water inlet. V. V pipes for conducting the liquid
from one chamber to the next, the top of each pipe being a little lower than the
preceeding one, and W is the liquor outlet In Figs 6 and 7 it will be observed the
strap of the cup R has a female thread which screws on to the male thread of
the tube P and by these means the cup is supported.
The action of the apparatus as applied to the dip-pipes and washers is the same,
for as the gas passes down the dip or short tube the pressure it exerts on the surface

page_text: of the liquid with which the hydraulic or washer is charged drives the liquid up
the sides of the cone in the form of small bubbles or spray, and as but little
pressure is sufficient to produce this effect the gas gets away readily from the dip
and short tube, while in the case of the washer from the constant supply of liquid
to the cups through the small orifices in the bottoms of them, the gas is efficiently
washed.
Having now described and particularly set forth the nature of this invention
and the manner in which the same is, or may be used or carried into effect I
would observe in conclusion that I do not confine or restrict myself to the precise
details or arrangements which I have described or referred to as variations may be
made therefrom without deviating from the principles or main features of this
invention, but what I consider to be novel and original and therefore claim as the
invention secured to me by the hereinbefore in part recited Letters Patent is
First Funnel shaped cups applied to dip-pipes in the manner herein described
and shown on the drawings,-and
Second. Washers constructed with tubes P P and cups R R arranged as herein
described and shown on the drawings
In witness whereof I the said John Somerville have hereunto set my hand
and seal this Nineteenth day of April in the year of our Lord One thousand
eight hundred and eighty four.
