PROVISIONAL SPECIFICATION.
An Improved Arrangement of the Appurtenances of Inclined Gas
Retorts.
We, WILLIAM ARMITAGE DRAKE, of the Firm of Jonas Drake & Son, of Ovenden,
Halifax, in the County of York, Gas Engineers, and JOHN SAMUEL MARSLAND, of the
same place, Manager, do hereby declare the nature of this invention
follows:-
to be as
This invention consists in a new construction and arrangement of some of the parts,
notably the hydraulic main, together with foul main, weir valve and box, liquor flush,
seal pot and tar main connected therewith, which hydraulic main and connections
have hitherto been fixed upon the upper cross girder of bench; but according to our
invention, we transfer the hydraulic main and connections on to lower girders in front
of the bench, thereby shortening the ascension pipes and bringing the hydraulic main
nearer to its work or near to the mouths of the retorts; thus with lowering the
position of these parts the ascension pipes do not get blocked up as soon as
formerly.
There are several commercial advantages in lowering the hydraulic main such as
shortening the length of piping, consequently the retort mouth pieces have less
weight to carry. By our invention we also obtain an increased amount of gas from
each inclined retort this being effected by reason of the hydraulic main being closer
to the mouths of the retorts. The hydraulic main is kept cooler with being removed
from the cross girder or bench; the removal of the apparatus is found to be much
more convenient and accessible for repairs and general alterations.

An Improved Arrangement of the Appurtenances of Inclined Gas
Retorts.
We, WILLIAM ARMITAGE DRAKE and JOHN SAMUEL MARSLAND, of the Firm of
Jonas Drake and Son, of Ovenden, Halifax, in the County of York, Gas Engineers,
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 is particularly applicable to inclined gas retorts and consists in a
new construction and arrangement of some of the parts, notably the hydraulic main,
together with foul-main weir valve and tar-box, liquor flush, and tar-main con-

nected therewith, which hydraulic main and connections have hitherto been fixed
upon the upper cross girder of bench; but according to our invention we transfer
the hydraulic main and connections on to lower girders in front of the bench thereby
shortening the ascension pipes and bringing the hydraulic nain nearer to its work
or near to the mouths of the retorts; thus with lowering the position of these parts
the ascension pipes do not get blocked up as soon as formerly.
The accompanying drawing illustrates our improved arrangement letter A denoting
the hydraulic main, and B the gas and tar outlet box. C represents the hydraulic
main or weir valve, and D the tar catch box. Letters E and F denote the gas and
tar mains respectively. G is the sludge cock.
The gas coming out of the retort issues through the mouthpiece K and through
the ascension pipe H, arch pipe I and dip pipe J finds its way into the hydraulic
main A, the ends of which are sealed. The gas then passes through the outlet
box B, valve C, and catch box D into the gas main E.
The tar with the other impurities fall to the bottom of the hydraulic main A and
rises outside through the tar and gas outlet-box B, thence through valve C when it
drops into the tar catch box D and passes down into the tar main F.
In case it is found necessary to clear the hydraulic main A, the sludge cock G is
opened, and the contents of the hydraulic main A pass into the tar pipe F. This
arrangement ensures the heavy matter being taken out of the bottom of the
hydraulic main first, whereby a light seal is always left on the dip pipe J. By the
arrangement above described and shewn in the drawing, we are enabled to obtain an
increased amount of gas from each inclined retort, this being effected by reason of
the hydraulic main A being much closer to the mouths of the retorts than hitherto.
The hydraulic main is also kept much cooler by being removed from the position it
previously occupied over the retort bench.
There are several other advantages obtained by our improved arrangement such as
shortening the length of piping required whereby the retort mouthpieces have less
weight to carry, and generally the apparatus is found to be much more convenient
and accessible for repairs or alterations whilst the cost is reduced.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The improved arrangement of the appurtenances of inclined gas retorts whereby
the hydraulic main together with the outlet and catch boxes, weir valve, sludge
cock and gas and tar mains are placed on low girders in front of the retort bench
substantially as shewn in the drawings and for the purposes herein described and set
forth.
