PETER INNES of 11. Bothwell Street, Glasgow in the County of Lanarkshire Gas
Engineer do hereby declare the nature of this invention to be as follows:-
*
The object of this invention is to form a multiple "anti-dip" arrangement, by which
a number of dip-pipes in any section of a Hydraulic Main" may be sealed, or
unsealed, by one operation; and to remove the thick tar from the bottom of the
Hydraulic Main"-hereinafter called the "Main "when the retorts are in
operation.
The preceding is accomplished by means of a shallow, longitudinal, basin, or tray.
semi-elliptical in section, and of sufficient length and breadth to embrace the dip pipes
in the interior of any section of the "Main."
This basin is made to tilt or sink on the front side, as follows. Along the upper
edge of the back side of basin is rivetted a square, or other section, bar of iron
prolonged to, and made to work in bearings fixed either to the division plate in each
section, or to cross bars in the "Main." This bar forms an axis round which the
basin will sink from, or rise to the horizontal position. A rod passing through a
stuffing box on the top of the "Main" is connected by a link and pin to the front
edge of the basin near to or at the centre of its length. The upper end of the rod is
fixed to a chain passing over a pulley working in bearings fixed on that portion of the
dip pipes above the "Main." From the other end of the chain hangs a counterpoise
weight which maintains the basin in its horizontal position. To sink the basin a
second chain passes over the pulley in an opposite direction, and by another pulley
between the "Ascension pipes" reaches down to the workman's hands. By pulling
down this chain, the weight is lifted, and the basin inside the "Main" sinks. Instead
of the first mentioned pulley, a three armed or inverted tee shaped lever may be used:

page_text: the weight hanging from one arm, the basin suspension rod and chain from the opposite
arm and the weight lifting chain from the vertical arm.
In using the apparatus the "Main" and its internal basin are charged with water or
gas liquor. The liquid runs into the basin first, and after reaching a height which
gives the desired seal to the dip pipes overflows into the bottom of the "Main" which
is also filled to its overflow level, a few inches below the level of the liquid in the
basin.
When the retorts are charged the gas will bubble through the liquid in the basin
as in the ordinary "Main." If it is desired to work without seal or "dip" the
counterpoise weight is lifted by means of the chain, the basin sinks, a portion of its
liquid runs into the "Main," the ends of the dip pipes become unsealed and the gas
passes away over the surface of the liquid. When the retorts are ready for recharging.
by relieving the chain-which in the interval has been fastened down in a convenient
place the weight raises the basin with sufficient liquid to again seal the dip pipes.
By a suitable pipe attached to the bottom of the "Main" the thick far can be run
off at any time by maintaining the basin in its horizontal position.
The preceding operations can all be accomplished without disturbing the process of
manufacture.

Improvements in Hydraulic Mains" Apparatus Used in the
Manufacture of Illuminating Gas.
PETER INNES 11 Bothwell Street Glasgow Gas Engineer, 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 consists of an apparatus by means of which, first, all the dip pipes,
in any section of a hydraulic main-such as that corresponding to an oven of retorts
may be simultaneously sealed or unscaled at pleasure, forming what may be termed
a multiple "anti dip"; and second, the hydraulic main may be relieved of thick tar
when the retorts are in operation.
Ր
The manner in which these results is obtained will be shewn from the accompanying
drawings. Fig. 1. is a cross section of an ordinary class of hydraulic main, with dip,
bridge, and part of ascension, pipes. Fig. 2 is a longitudinal section of the same, for
an oven, or setting, of five retorts. In fig. 1. a is one of the dip pipes shewn sealed,
or dipping, in the liquor contained in the basin. The basin is held in the horizontal
position-sealing the dip pipes-by the weight acting through the bell crank, chain,
and rod d passing through the stuffing box on the top of the hydraulic main-herein-
after called the "main." The rod is connected to the basin by a link, or knuckle
joint, fixed at its lower end to a cross bar between the upper edges of the basin.
fig. 2 the arrangement is seen fixed between the centre and adjoining, dip, bridge, and
ascension pipes. In a section of "main" containing 4, 6, or dip pipes, it would be
placed in the centre of the section. The basin is constructed of sheet iron or steel,
and weighted if necessary to overcome any floatage. The ends of the square bar of
iron rivetted along the back upper edge, are finished to work in the bearing bolts
passing through the top of the "main."
In
In using the apparatus, say for the first time-water or liquor is run into the
basin from the pipe h. fig. 2-which is connected to an overhead tank, or other source
of supply, until sealing the dip pipes; and overflowing into the lower part of the
"main," through a number of oblong holes, shewn in fig. 2 between the water level,
and the square bearing bar. The water is shut off when it has reached its proper
level in the "main," indicated by an open tap, or other adjustment. The basin is kept
in the horizontal position until the retorts are charged, the gas as it evolves passing
through the dip pipes sealed in the basin, as in the ordinary "main." By pulling down
the chain S the basin sinks to the inclined position shewn by its dotted form, fig. 1,
losing sufficient liquid to unseal the dip pipes and permit the gas to flow freely away
from the retorts without any obstruction. Before recharging the retorts, the holding
down chain-which in the interval has been secured to the ear of one of the retort
mouthpieces, or any other convenient fastening is relieved, the basin rises to the
horizontal position, carrying with it sufficient liquid to again seal the dip pipes. The
retorts are again charged, the basin lowered, and so on.

page_text: When at any moment, it is desired, to remove the thick tarry matter, which accumu
lates in the bottom of the "main" without interrupting the process of manufacture,
the basin is raised to the horizontal position; the cock (is opened and the tar allowed
to run, as for example, into the foul main as shewn in fig. 1. Gas issuing from the
vertical pipe indicates when the "main" is empty. The cock G is then shut, the
water supply turned on, and the "main" refilled by overflowing from the basin,
which when completed, the basin may be again lowered as described before.
According to the size and shape of the "main" in use, the basin may vary in cross
sectional shape, forming, as it may be, part of a circle, ellipse, or other curve found
most suitable. The arrangement for lowering the basin may likewise vary, for
example, a large pulley placed opposite the small one may be substituted for the bell
crank. Again on the end sections of an extent of "main," the basin may be actuated
by prolonging the outer bearing on each end section, through a stuffing box on the
end cover plate of the main, as for example at the position fig. 2.-and fixing on it
a lever, the counterpoise weight depending from the back arm, and the chain to lower
the basin from the front arm, of the lever.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed 1 declare that what I claim is
1st. The movable basin in the interior of the hydraulic main, whereby all the
advantages of "anti dips," can be simply and safely obtained in a multiplied form,
the whole dip pipes in the section, being also sealed or unsealed, practically by one
operation, and
2nd. By means of the basin in its horizontal position, the "main" can be safely and
entirely, emptied of its contents, at any time, and without interruption to the
manufacture of the gas.
