page_text: LETTERS PATENT to Samuel Chandler and Josiah Chandler, both of 104,
Newington Causeway, in the County of Surrey, Gas Engineers, for an
Invention of "IMPROVEMENTS IN GAS APPARATUS.'

Josiah Chandler at the Office of the Commissioners of Patents on the 18th
February 1880.

The apparatus we employ for applying our improvement is a horizontal or
vertical vessel made of iro, and is divided into separate compartments, in each of
which we place vertical or horizontal sheets of iron or other material, separate or
otherwise, extending the whole width of vessel, but terminating at a given distance
from top and bottom of same; each division plate also terminates at a like distance
altornately so as to give the gas an upward and downward course through the
vessel, or by our employing additional division plates cause the gas to travel
always in an upward direction through the clusters of purifying material, and
descending the blank bay in each case, and so on through the vessel.
We employ a suction and throw pump to cach bay for drawing the liquor from
bottom of tank and delivering it into a perforated trough which is situated at top
of the vessel for distributing the liquor over the purifying material for the purposes
of purifying gas from impurities such as ammonia, carbonic acid, and sulphuretted
hydrogen.

Office on the 13th August 1880.
SAMUEL CHANDLER and JOSIAH CHANDLER, both of 104, Newington Causeway,
in the County of Surrey, Gas Engineers. " IMPROVEMENTS IN GAS APPARATUS."
The apparatus we employ for applying our improvement is a horizontal or
vertical vessel made of iron, and is divided into separate compartments, in each of
which we place vertical or horizontal sheets of iron or other material, separate or
otherwise, extending the whole width of vessel, but terminating at a given distance
from top and bottom of same; cach division plate also terminates at a like distance
alternately so as to give the gas an upward and downward course through the
⚫ vessel, or by our employing additional division plates cause the gas to travel always
in an upward direction through the clusters of purifying material, and descending
the blank bay in each case, and so on through the vessel.
We employ a suction and throw pump to each bay for drawing the liquor from
bottom of tank and delivering it into a perforated trough, which is situated at top
of the vessel, for distributing the liquor over the purifying material for the purposes
of purifying gas from impurities such as aminonia, carbonic acid, and sulphuretted
hydrogen.
Having indicated what our improvements consist of, we now proceed more fully
to describe the nature thereof, and the means we employ to carry the same into
effect, with reference to the accompanying Drawings.
Figure 1 on the Drawing shows a longitudinal sectional elevation of a horizontal
vessel of square or other form constructed substantially of cast or wrought iron, or
other material, the inside of which is divided by partition plates extending the
whole width of the vessel, as shown on transfer section, Figure 2, but terminating
within a given distance from bottom and top of the said vessel alternately, and
between these partition plates the scrubbing material of any approved kind is
placed, but we prefer to use clusters of iron sheets, as shown at letter A on Figure 1,
kept apart by means of dimples in the plates or sheets so as to allow the gas to
pass between.
In each partition plate, which extends to the bottom of the tank, we fix an
overflow pipe (see letter B) for the purpose of conveying the liquid from compart-
ment to compartment, and so on to the end, from whence it leaves for the ammonia
well.
It will be seen that each pipe is arranged so as to allow tho fluid to flow by
gravitation.
Clean water is admitted by a pipe at C, and leaves at D charged with a strong
solution of ammonia and other impurities.
The distributor marked E is a pipe of any shape finely perforated, through
which the water or other liquid delivered by the pump percolates and descends
on and through the scrubbing inaterial, thus presenting a wetted surface for tho
purification of the gas.
We employ an ordinary suction and force pump F attached to the exterior of the
vessel, one to and for the use of each compartment, which when workod by suitable
gearing draws the liquid from the bottom of the compartment and forces it into the
distributor referred to, and so on to the scrubbing material, as previously stated.
The course of the gas is as shown by the arrows in Figure 1, but may be reversed
as indicated by the arrows at Figure 4.
Figure 3 shows exterior of Figuro 1; Figures 5 and 6 show our Juvention carried
out in a vertical vessel, and the course of the gas is shown by arrows, but may be
reversed as in the former case.
Figure 7 is an ordinary suction and force pump as applied to our distributor.

page_text: We would add that we are aware that the application of pumps for pumping
liquor or other solutions over and over again is not a new idea, but what wo claim
as our Invention is,-
" scrubber
Firstly. Applying a "series" of pumps in connection with a "single
washer, and thus being enabled to obtain liquors of varied strengths in different
bays, which may be worked over and over again.
Secondly. Tanks divided and arranged as herein described.
Thirdly. Placing material for scrubbing inside such tanks, as herein set forth.
In witness whereof, we, the said Samuel Chandler and Josiah Chandler,
have hereunto set our hands and seals, this Twelfth day of August, in the
year of our Lord One thousand eight hundred and eighty.
