IMPROVE- MENTS IN GAS CONDENSERS
Year: 1881

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey, both of
Frome, Selwood, in the County of Somerset, for an Invention of "IMPROVE-
MENTS IN GAS CONDENSERS."
PROVISIONAL SPECIFICATION left by the said Henry Cockey and Francis
Christopher Cockey at the Office of the Commissioners of Patents on the
10th June 1881.
HENRY COCKEY and FRANCIS CHRISTOPHER COCKEY, both of Frome, Selwood,
in the County of Somerset. "IMPROVEMENTS IN GAS CONDENSERS."
This Invention has for its object the construction of gas condensers in such a
manner as to render them more convenient, more readily cleaned without throwing
the apparatus out of use, more easily regulated, and more generally efficient than
those commonly in use.
The Invention consists of a tank supplied with water in which horizontal pipes
are immersed, the said pipes being placed in two or more series, one above the
other. The ends of the said pipes pass through and protrude beyond each end of
the tank, and are there connected together and provided with removable lids or
covers. Each lid or cover at one end of each pipe is furnished with a stuffing box
through which passes a turned hollow rod or bar, the outer end of which is screwed
so as to permit of its being joined to another longer rod also screwed and made
with a cross handle, while the inner end of the rod first mentioned is attached to
an angle iron ring that fits the interior of the pipe, but not so closely but that it
may be freely moved. During the condensation of the gas a deposit takes place,
and as any considerable accumulation of such deposit interferes with the efficiency
of the apparatus, the angle iron ring or scraper has been devised for its removal,
and by screwing the handled rod to that part of the short rod outside the stuffing
box and pushing it, the scraper will be thrust forward, driving before it any deposit
that may exist, until it reaches near the opposite end of the pipe, when the deposit
ID 11

page_text: will fall through a suitably sealed pipe into a receiver below, from whence it may
be easily removed. To this receiver is also attached a pipe by which the tar and
liquor may be run off into any appropriate receptacle. The water tank may also
he fitted with steam pipes passed round the inside of the tank near the bottom for
raising the temperature of the water during frost, or at any other time when required,
Bo as to bring the temperature of the gas under perfect controul.
In carrying our Invention into practice, we find it advantageous to introduce at
certain points one or more devices known as "Rutter's gas distributors." These
break up the gas into thin streams, and cause the tar to deposit more freely, thus
increasing the efficiency of our apparatus.

HENRY COCKEY and FRANCIS CHRISTOPHER COCKEY, both of Frome, Selwood,

This Invention has for its object the construction of gas condensers in such a

the apparatus out of use, more easily regulated, and more generally efficient than
those commonly in use.
The Invention consists of a tank supplied with water in which horizontal pipes
are immersed, the said pipes being placed in two or more series one above the
other. The ends of the said pipes pass through and protrude beyond each end of
the tank, and are thero connected together and provided with removable lids or
covers. Each lid or cover at one end of each pipe is furnished with a stuffing box
through which passes a turned hollow rod or bar, the outer end of which is screwed
so as to permit of its being joined to another longer rod also screwed and made
with a cross handle, while the inner end of the rod first mentioned is attached to
an angle iron ring that fits the interior of the pipe, but not so closely but that it
may be freely moved. During the condensation of the gas a deposit takes place,
and as any considerable accumulation of such deposit interferes with the efficiency
of the apparatus, the angle iron ring or scraper has been devised for its removal,
and by screwing the handled rod to that part of the short rod outside the stuffing
box and pushing it the scraper will be thrust forward, driving before it any deposit
that may exist, until it reaches near the opposite end of the pipe, when the deposit
will full through a suitably sealed pipe into a receiver below, from whenco it may
be easily removed. To this receiver is also attached a pipe by which the tar and
liquor may be run off into any appropriate receptacle. The water tank may bo
also fitted with steam pipes passed round the inside of the tank near the bottom
for raising the temperature of the water during frost, or at any other time when
required, so as to bring the temperature of the gas under perfect controul.
In carrying our Invention into practice, we find it advantageous to introduce at
certain points one or more devices known as
" Rutter's gas distributors." These
break up the gas into thin streams, and cause the tar to deposit more freely, thus
increasing the effeciency of our apparatus.
In order that the foregoing may be more easily understood, Drawings are attached
hereto, of which the following is a description:-Fig. 1 is partly a side elevation
and partly a side sectional elevation; Fig. 2 is a plan; Fig. 3, a front end
elevation; Fig. 4, a transverse section through A, B, Figs. 1 and 2, and Fig. 5, a
back end elevation of the tank and condensing pipes. In each of the Figs. C
represents the tank charged with water, and in which the condensing pipes D are
arranged and connected together, as shown in the different views. E is the angle
iron scraper attached to the hollow rod F, which is jointed with male and female
screws, one extremity being fastened to the scraper, and the other end furnished
with a cross handle G. In the upper pipe in Fig. 1, the scraper is shown as in uso
when it is employed to remove and drive before it any incrustation, and in the
lower pipe the scraper is exhibited in the position in which it lies when out of
action. H, H, are the stuffing boxes through which the rods F slide, and I, I, are
guides or keys to prevent the scraper turning round when screwing the parts of
the rods together. J is a "Rutter's distributor " before referred to, and K is a box
or chamber to receive the tar liquor, and any deposit that may be removed by
the scraper, while L is a pipe for conveying away the tar and liquor to any suitable

page_text: receiver, M, M, are the removable lids at each end of the pipes, and N, N, are
blank flanges to connections provided for the attachment of another series of
condensing pipes whenever it becomes necessary to extend the apparatus, or to
open it for other purposes.
The gas enters at the inlet O, and pursuing the course indicated by the arrows
in Figs. 1, 2, 3, and 5, makes its exit at the outlet P, and the tar liquor and
deposit removed by the scraper fall through the connections Q and R, and down
the pipes S and T which are scaled by the liquid in the receptacle or chamber K.
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, we
would observe in conclusion that we do not confine or restrict ourselves to the
precise details or arrangements that we have described or referred to, as variations
therefrom may be made without deviating from the principles or main features of
this Invention, but what we consider to be novel and original, and therefore claim as
the Invention secured to us by the herein-before in part recited Letters Patent is,-
1st. The construction and application of the scraper E and rod F, as herein
described and shown on the Drawings.
2nd. The construction and general arrangement of the condensing pipes and
chamber K, so as to admit of the efficient use of the scraper, and as herein described
and shown on the Drawings.
In witness whereof, we, the said Henry Cockey and Francis Christopher
Cockey, have hereunto set our hands and seals, this Eighth day of
December, in the year of our Lord One thousand eight hundred and
eighty one.
