Improvements in or connected with Gullies and Drains.
We WILLIAM GORDON CROW of "The Grave Maurice" No. 128, White-
chapel Road, Licensed Victualer, and SOLOMON LEHMON of No. 217, Salmon's
Lane, Limehouse, Umbrella Maker, both in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in or connected with gullies and drains,
whereby the escape of stench. is prevented, and at the same time a thorough
cleansing of the gully or drain is effected.
According to our invention we place in the gully or drain an apparatus by
means of which a current of air can be impelled down the gully or drain, 80
that any offensive or poisonous gases coming from the sewer will be met by the
current of air and be prevented from escaping into the street or house where, the
gully or drain is located.
The apparatus we employ may consist of a removeable framework carrying an
axis or spindle, furnished with two sets of vanes and capable of freely revolving
in suitable bearings in the framework. One set of these vanes is so arranged
that a jet or jets of water can be caused to impinge upon the vanes in such a.
manner as to revolve the axis or spindle, while the other set of vanes is so
arranged that as the axis or spindle revolves a current of air will be impelled
down the gully or drain.
As the axis or spindle revolves the water, after impinging upon the vanes, is
thrown off by centrifugal force and strikes against the sides of the gully or
drain, thereby keeping it always thoroughly cleansed and free from filth.
The framework carrying the revolving axis or spindle is made of such dimensions
as to fit into the gully or drain and rest upon suitable supports provided for the
purpose. By reason of the whole of the apparatus being carried by this frame-
work, which as before stated is removeable, not only can access be readily had
to the gully or drain when necessary by merely lifting out said framework; but
inspection or repair of the apparatus can also be conveniently effected.
The nozzles through which the motive water is projected upon the driving vanes
may be provided with stopcocks for shutting off the flow of water, and said
nozzles may also be arranged in such a manner as to permit of their being turned
out of the way when it is required to remove the apparatus from the gully or
drain.
The apparatus may advantageously be formed of. galvanized iron or other
non-corrodible material.

Improvements in or connected with Gullies and Drains.
We, WILLIAM 'GORDON CROW of "The Grave" Maurice," No. 128, White-
chapel Road, Licensed Victualer, and SOLOMON LEHMON of No. 217, Salmon's
Lane, Limehouse, Umbrella Maker, both in the County of Middlesex 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 relates to improvements in or connected with sewer.ventilators,

page_text: By fitting our apparatus into one or more of the ventilators in a certain district,
a current of fresh air may be driven into the sewer and be caused to mix with
the impure gases, which, after becoming more or less oxidized thereby, will escape
from other ventilators in a practically harmloss and inoffensive condition.
If preferred, instead of forcing the air down into the sewer, we may, by simply
arranging the nozzle g on the opposite side of the apparatus, causo the spindle
to revolve in the reverse direction and thereby induce a current of air up those
ventilators in which the apparatus is located, the fresh air being then drawn
down into the sewer through those ventilators which are unprovided with our
apparatus.
If considered advisable, only those ventilators which are situated where there
is least traffic, need be employed for allowing the escape of the current of air
induced in the sewer; or special outlets may be provided in isolated places, for
the escape of the air.
It is obvious that by altering the shape or construction of the framework or
casing e, our apparatus can be readily adapted for use with drains or gullies, or
with ventilators of different shape to that shewn in the drawings.
We also wish it to be understood that, although water power is more advan-
tageous for driving the apparatus, we do not confine ourselves thereto, as any.
desired and suitable means may be used for the purpose.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:—
1. The use, with sewer ventilators, gullies or drains, of an apparatus or "stench
annihilator" constructed substantially as hereinbefore described and shewn, whereby
a current of air can be induced in the sewer, as and for the purpose set forth.
2. The apparatus or "stench.annihilator," consisting of a suitable framework or
casing carrying a revolvable axis or spindle furnished with two sets of vanes or
blades, one set serving to enable the said axis or spindle to be revolved and the
other to produce a current of air, substantially as hereinbefore described and shewn
by the annexed drawings; and for the purpose specified.
3. Our improvements in or connected with sewer ventilators, gullies and drains
substantially as hereinbefore described and shewn by the annexed drawings.
