Improved Devices for Facilitating the Cleansing of
Preventing the Obstruction thereof.
Drains and
1., STEPHEN GEORGE HUNTLEY, of No. 9, Duke Street, Adelphi, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows :-
--
My invention relates to improvements in devices for facilitating access to drains
for the purpose of sweeping, flushing, and generally cleansing them; and thereby of
preventing their obstruction.
In carrying it into effect, I provide a frame or box adapted to be let into the floor,
or ground, flush therewith; and form a nozzle on the bottom of the box, making an
acute angle therewith. This nozzle is connected with the drain by an oblique line of
pipe making a corresponding acute angle therewith. It is obvious that the more
acute the angle which the cleaning pipe makes with the drain, the easier will it be to
introduce the cleansing brush into the latter and to work it to and fro.
I provide a water seal in the drain in front of the junction of the cleaning pipe
therewith, and also a pipe charged with the function of supplying a ventilating
current to the drain pipe.
"The top of the box aforesaid is rebated, and in the rebate I form a groove filled
with bitumen-felt or equivalent packing. The cover is adapted to fit within the
sides of the box and into the groove.
I form a second and similar groove in the bottom of the box, and provide a second
and similar cover and packing.
I provide a transverse bar which engages under projections on the inner faces of
the sides of the box, and a screw working vertically in said bar, for the purpose of
holding the second cover closely down upon its seat.
For the sake of improving the joint between the said second cover and its seat
I prefer to fill the space between the sides of the box and the cover with fine sand or
equivalent material.
Dated this 28th day of September 1887.

I, STEPHEN GEORGE HUNTLEY, of No. 9, Duke Street, Adelphi, 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 :—
My invention relates to improvements in devices for facilitating access to drains
for the purpose of, sweeping, flushing, and generally cleansing them, and thereby
preventing their obstruction."
In order that my invention, and the means by which it is to be carried into
practical effect, may be thoroughly understood, I will now proceed to describe the
same in detail, referring in so doing to the accompanying drawings which are to be
taken as part of this specification, and read therewith.
Fig. 1 is a sectional elevation through a drain, illustrating the application of my
invention thereto.
Fig. 2 is a transverse elevation taken on the line of Fig. 1.
Fig. 3 is a sectional elevation of a drain to which my invention has been applied,
illustrating the application of a brush through the opened mouth of the cleansing or
flushing pipe.
Fig. 4 is a plan of the frame after the cover has been removed.
Fig. 5 is a plan of the frame after the mouth of the nozzle has been uncovered.
A is a frame of suitable material, preferably cast-iron or stoneware; and B, the
pavement or roadway in which it lies, flush with the surface thereof. C is a nozzle
making an acute angle with the underside of the frame, A, and adapted to be
connected with the pipe, D, which joins the drain, E, by means of the junction
pipe, F.
The angle which the pipe, D, makes with both the ground level, B, and the
drain, E, is decided by considerations of convenience; it being evident that the
more the pipe D slopes, the easier will it be to work a drain-brush backwards and
forwards in the drain."
G is the removable cover of the frame, A; and g, its scat. Ï form a ridge, g', on
the underside of the cover near its edge, and a corresponding groove in. the sent, g.
This groove is provided with a packing, g², of bitumen-felt, gaskin, rubber, or other
suitable material.
H is a second cover provided for the purpose of sealing the nozzle C. Like the
cover, G, it has a ridge, h, formed on its under side near its edge, which ridge, like
that on the underside of the cover, G, engages in a groove, ', provided with a
packing, 2, of bitumen-felt, gaskin, rubber, or other suitable material.
I is a transverse bar the ends of which engage under projections, i, i, formed in the
sides of the frame A.

Jis a set-screw adapted, when screwed down upon the cover H, to drive it into
tight contact with its seat. The cover is strengthened by the addition of ribs, h³.
For the purpose of maintaining this contact gas-tight after it has been made, a layer
of sand, j, is led around the outer line of junction.
K is a water seal in the drain provided by the introduction into the said drain of a
syphon formed to a gentle curve; and. L is part of a ventilating pipe.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of frame, removable cover adapted to fit the same tightly,
nozzle projecting from the bottom of the said frame and removable cover adapted to
close the mouth thereof gas-tight and to be held down thereupon; as set forth.
2. The combination with a drain of an inclined or sloping pipe joining the said
drain at an angle convenient for the introduction from the ground of a drain-brush
through said sloping pipe into the said drain as set forth.
3. The combination of frame having removable cover, nozzle projecting from the
bottom of said frame at an angle therewith and fitted with a removable cover and a
sloping pipe by means of which the said nozzle can be placed in communication with
the drain for the purpose of introducing a drain-brush through it into said drain as
set forth.
