PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Quenching or Cooling Coke Produced
in the Manufacture of Coal Gas.
I WILLIAM PARLBY, Gas Engineer, of Mortimer House, Mortimer Road,
Hereford in the County of Hereford, do hereby declare the nature of this invention
to be as follows :-
This invention for improvements in apparatus for quenching or cooling coke
produced in the manufacture of coal gas has for its objects to prevent or greatly
diminish the production of steam in the process of cooling the coke inside retort
houses, to quickly remove the coke when drawn from the retorts from the retort
house and thus facilitate the work performed in the retort house by coke
wheelers, and to avoid the labour and inconvenience usually caused to the coke
wheelers by their having to lift and to throw the water by hand over the hot coke to
quench it; and consists in wheeling the barrows containing the coke below a
water supply and in showering in a particular manner a spray or sprays of water
from the supply on to the coke and thus quenching or cooling the same mechanically
instead of by hand labour.
In one form of apparatus the hot coke is brought out of the retort house in
barrows which are wheeled under an overhead tank erected on piers or columns,
and there quenched or cooled by a shower of water issuing from a series of holes in
a horizontal pipe. This overhead tank is supplied with water either by gravitation
or other method, and is provided with a ball valve to close off the water when full."
A valve is fixed to the bottom of the tank inside, which communicates with a
horizontal pipe underneath the tank outside so that by actuating a lever a shower.
of water is delivered in a particular manner from the pipe underneath the tank on
to the hot coke in the barrow below which speedily cools the same.

Improvements in Apparatus for Quenching or Cooling Coke Produced
in the Manufacture of Coal Gas.
I, WILLIAM PARLBY, Gas Engineer, of Mortimer House, Mortimer Road,
Hereford, in the County of Hereford, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention for improvements in apparatus for quenching or cooling coke.

page_text: produced in the manufacture of coal gas has for its objects to prevent or greatly
diminish the production of steam in the process of cooling the coke inside retort
houses, to quickly remove the coke when drawn from the retorts from the retort
house and thus facilitate the work performed in the retort house by coke
wheelers, and to avoid the labour and inconvenience usually caused to the coke
wheelers by their having to lift and to throw the water by hand over the hot
coke to quench it, and consists in wheeling the barrows containing the coke below
a water supply and in showering in a particular manner a spray or sprays of water
from the supply on to the coke and thus quenching or cooling the same mechanically
instead of by hand labour.
In one form of apparatus the hot coke is brought out of the retort house in
barrows which are wheeled under an overhead tank erected on piers or columns,
and there quenched or cooled by a shower of water issuing from a series of holes
in a horizontal pipe. This overhead tank is supplied with water either by
gravitation or other method, and is provided with a ball valve to close off the
water when full. A valve is fixed to the bottom of the tank inside, which
communicates with a horizontal pipe underneath the tank outside, so that by
actuating a lever a shower of water is delivered in a particular manner from the
pipe underneath the tank on to the hot coke in the barrow below, which speedily
cools the same.
In the accompanying sheet of illustrative drawings Fig. 1 is a front elevation of
a coke quenching apparatus constructed according to this invention, Fig. 2 is a
plan of the same and Fig. 3 is a detail view.
A set of cast iron columns a are arranged to support girders & carrying an over-
head water tank a fixed thereon and fed with water through a supply pipe à fitted
with a ball valve A¹ to close off the water when the tank is filled, the height of
water in the tank being shown by an indicator g. The tank c has an opening in'
the bottom fitted with a specially constructed valve d consisting of a valve proper o,
valve scat p, a perforated cover t, and guides u, for the valve rod v. The guides u,
and valve seat p, are secured to the bottom of the tank by bolts w; the valve
being actuated through the connecting rod a by a levere and chain f. The
opening in the cistern e, normally closed by the valve d, communicates through a
pipe n, with a horizontal perforated pipe i, closed at the ends and forming the
sprinkler. In order that the cooling water may be used over again a tank k,
shown in dotted lines in the drawing, is arranged to receive the same after passing
through the coke and convey it through an overflow pipe 1, to convenient storage
tanks from whence it is raised by steam or other power and delivered through a
pipe m, to the tank c, for re-use. When using the apparatus as before described
the coke to be quenched is conveyed underneath the sprinkler i, in barrows j, and
the valve d raised by means of the lever e, and chain, allowing the water to flow
from the tank e, through the pipe n, to the sprinkler i, from which it descends in a
finely divided condition onto the coke and passing through is collected in the tank k
and conveyed through the pipe to the storage tank and afterward forced into the
tank e for re-use either alone or with fresh water from the supply pipe.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. In apparatus for quenching or cooling coke, an overhead water tank, an open-
work frame supporting the tank, an elongated sprinkler underneath the tank and
connected to the water tank through a valve regulated by a lever so that the coke
can be wheeled underneath the sprinkler and be quenched whilst in the barrow,
substantially as described.
2. In apparatus for quenching or cooling coke an overhead water tank, an open-
work frame supporting the tank, an elongated sprinkler underneath the tank and
connected to the water tank through a valve regulated by a lever and a collecting
tank below for collecting the used water and a storage tank into which the used

page_text: water is conveyed from the collecting tank and stored for re-use substantially as
described.
3. The improvements in apparatus for quenching or cooling coke produced
in the manufacture of coal gas substantially as described with reference to the
drawings.
