Improvements in Interceptors for Sewer-drains.
I, JOHN YOUNG, trading as J. Young & Co., of Kennington Cross, London, S.E.,
Glass, Lead and Iron Merchant, 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 interceptors as now in use to form a
trap-junction between the drain of a house or other establishment, and the main or
other sewer, the object of my invention being to so construct and arrange the said
interceptor, and to provide means by which the same can be periodically inspected,
cleansed and emptied from the ground surface, without the need of the expensive
manholes now in use, as a means for reaching the said interceptors.
In order that my said invention, its particular construction, and the manner of
its use, may be fully understood, I have appended hereunto a sheet of drawings of
which.
Figs. 1 and 2 are side elevation and end elevation respectively of my said
improved interceptor, while Fig. 3 is a plan or top view of same with its vertical
connections removed.
Fig. 4 is an elevation similar to Fig. 1, but illustrating an alternative method of
construction.
The interceptors of the type to which my invention refers are usually placed a few
feet below the ground surface, and generally situated in some part of the premises
of the house or establishment to the drains of which the said interceptor is con-
nected, and such interceptor has hitherto been accompanied by a brick and cement
built manhole, the diameter of which must, at the least, be large enough to permit
a man of ordinary size to pass down in order to get at the said interceptor when the
same has become choked or otherwise needs attention, and such manholes, apart
from the cost of their construction and maintenance, are frequently the cause of
the blockage of the syphon of the drains, by reason of the falling cement and face
of the brickwork of which they are constructed, but according to my invention all
those inconveniences are entirely prevented, and the expenses attending the initial
cost and maintenance considerably reduced.
My invention consists of a casting of metal, or stoneware, or any desired com-
bination of both, the said casting being so formed at its lower or bottom surface
as to provide a flat and suitably shaped base A, by which it may be firmly seated
upon a brickwork or cement foundation B. The said casting expands from its said
base and forms a basin C, capable of holding sufficient liquid 1) to form a water
seal, or stink trap between the inlet junction or junctions sockets E of the inter-
ceptor, and the drain pipe or pipes F coming from the house or premises being
drained, and the outlet junction G of the interceptor, to which is connected the
ocket pipe H, leading to the main drain or sewer.
The said casting may be of any desired height above the level of E and G, and has
formed on its upper surface two flanged openings J and K, to the former of which is
connected a length or lengths of vertically or approximately vertically placed pipe
or pipes L, the upper extremity of which terminates at or about level with the

page_text: ground M. The diameter of the pipe or pipes L and the flanged openings J, and
the position of these relatively to the passage GH, being such as to permit a
clearing rod to be easily passed down through L and J from the ground level into
the passage H, or the basin C, for the purpose of removing any obstruction in the
former, or and for agitating any deposit that may be collected in the latter
The opening K is preferably larger than the opening J, and has connected
thereto a length or lengths of vertically, or approximately vertically placed pipe
or pipes N, the upper end of which terminates level with the upper
end of L, the diameter of K and N being such as to permit the easy
passage of a rod or pole having a scoop at its lower end, by means of
which all sediment accumulated in the basin C, (and which may as before stated
have been previously agitated by a rod entering through L, J,) may be brought
up and deposited upon the ground M, and if necessary the said interceptor and
drain may be flushed with water, by the means of a flexible conduit passing down
into N, and by these means I am enabled to clear and cleanse the said interceptor
from the ground surface without the need of a manhole.
The division 0 between J and K must of necessity be of such depth as to dip
down into the basin C, below the level of the liquid D therein, and such division
may be divided as in Fig. 1, or be formed solid as in Fig. 4, as desired.
The upper or ground surfaces of both L and N may be closed by any suitable
form of air tight cover P and P¹, but I prefer to use, and where possible should at
all times use, for this purpose, my improved inspection chamber cover forming the
subject matter of my Patent No. 23589%.
I am aware that means for inspecting and clearing interceptors without the use
of a manhole have been devised prior to my invention, but I am not aware that
an interceptor of the character of mine, with vertical passages leading to the
ground surface, one of which, N, is adapted to admit of the insertion of a pole or
rod, with a scoop at its lower end, for clearing out the matter likely to accumulate
in the basin C, have ever been used or described in any printed publication prior
to my said invention, therefore,
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 improved interceptor for drains herein described and shewn, with
vertical passages leading therefrom to the ground surface, one of which being to
permit the rodding or clearing, and the other for scooping out or emptying the
same, from the ground surface, both the said passages being closed by air tight
covers, substantially as herein set forth and shewn.
(2) The improved interceptor, consisting of a casting having a base A, basin C,
and one or more flanged or socketed openings E for connection to the house or
other establishment drain F, and an opening G, for connection to the main drain H,
with socketed openings J and for the reception of vertical pipes L and N, the
latter being of such internal diameter as to permit the insertion of a scoop for
clearing out C, and both terminating at or about level with the ground surface M,
and provided with air tight covers P and P1, the said openings J and K being
separated by a partition O, solid as at Fig. 4, or divided as at Fig. 1, and dipping
down into the basin C, below E and F, substantially as and for the purposes herein
described and shewn by the accompanying drawings.
