PROVISIONAL SPECIFICATION.
Improvements in or connected with Drain Pipes.
I, ARTHUR AUGUSTUS WINCOTT, of Foleshill Road, Coventry, in the County of
Warwick, Builder, do hereby declare the nature of this invention to be as follows:
-
This invention relates to improvements in the construction or arrangement of
drain pipes, and its object primarily is to provide improved means whereby a
number of drains may be readily directed into a general manhole, or other place
or channel, although they may lead thereto at varying angles.
In present practice, to accommodate these varying angles of direction of the
several drains, a number of bend pipes and bend channels having varying angles
have to be kept in stock, from which to select that which is most suitable. In my
invention I obviate this difficulty as follows:-
At or near the entrance of the drain into the manhole I provide a bend pipe
whose forward end engages and discharges itself into a suitably shaped socket
or recessed collar in the said manhole; its other end being connected to the drain
in the usual manner. The bend pipe is preferably further provided with a hole
by which cleaning &c. may be readily effected from time to time when required,
such hole being covered by a cap secured by any suitable means. The bed of
the manhole is formed of blocks having uniformity of size and shape with over-
lapping or rebating edges, so that when placed together their joints shall be the
Certain of these blocks have formed in them outlet channels having
upon their upper side the collars or sockets before named and with which the bend
pipe is connected.
more secure.
Thus while the manhole bottom consists of these uniformly placed blocks, the
various drains approach from different directions, but by means of the bend pipe
and the recessed collar or socket the connection can be readily made to suit any
such angle and at the same time afford a more direct course of flow, lessening
liability to obstruction, more effectual flushing and in cases where deep manholes
occur further obviates a considerable amount of excavation.

Improvements in or connected with Drain Pipes.
I, ARTHUR AUGUSTUS WINCOTT, of Foleshill Road, Coventry, in the County of
Warwick, Builder, 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 the construction or arrangement of

page_text: drain pipes, and its object primarily is to provide improved means whereby a
number of drains may be readily directed into a general manhole, or other place
or channel, although they may lead thereto at varying angles.
In present practice, to accommodate these varying angles of direction of the
several drains, a number of bend pipes and bend channels having varying angles
have to be kept in stock, from which to select that which is most suitable. In my
invention I obviate this difficulty as follows, and in order to more clearly explain
this my invention I have appended hereunto an illustrative drawing upon which
are figures and numbers of reference, similar numbers referring throughout the
several views to the same thing or part.
Fig. 1, is a plan view of a manhole arrangement according to this my invention.
Fig. 2, is an end section of the manhole and pipes on line A-B Fig. 1.
4, is the man hole which is usually below the ground 5 being the walls around it.
Into this man hole the drains from various directions are carried as shown for
instance by arrows 6, 7, 8, 9, 10, 11 and 12. The height at which these, enter the
man hole may also vary as shown by way of example in Fig. 2, where the drain 9,
is shown to enter at a higher point than drain 10, by means of an extension
pipe 13ª
At or near the entrance of the drain into the man hole I provide a bend pipe 13,
whose forward end engages and discharges itself into a suitably shaped socket or
recessed collar 14, in the said man hole; its other end being connected to the drain
in the usual manner. The bend pipe is further provided with a hole at 15, by
which cleaning &c. may be readily effected from time to time when required,
such hole being covered by a cap 16, secured by any suitable means. The bed
of the manhole is formed of blocks 17, having uniformity of size and shape with
overlapping or rebating edges at 18 and 19, so that when placed together their
joints shall be the more secure. Certain or all if desired of these blocks have
formed in them outlet channels 20, having upon their upper side the collars or
sockets 14, before named and with which the bend pipe is connected. These out-
lets or channels 20, are all made to curve in the one direction with the outflow
from the manhole, and thus to induce ready flow. Thus with the manhole bottom
consisting of 'these uniformly placed blocks 17, the various drains may approach
from different directions, and by means of the bend pipes 13, and the recessed
collars or sockets 14, the connection can be readily made to suit any such angle
and at the same time afford a more direct course of flow, lessening liability to
obstruction, more effectual flushing, and in cases where deep manholes occur
further obviates a considerable amount of excavation.
Particular attention for instance might perhaps be drawn to drain 11, where it
enters at an angle which is contrary in its direction to the outflow of the manhole,
but by reason of the bend pipe 13, and the outflow 20, its flow is readily and
smoothly redirected to that of the manhole.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
1. Constructing the bottoms or beds of drain manholes with blocks 17, having
the curved outlets 20, and sockets 14, substantially as set forth and shown.
2. The combination with a drain pipe of a curved outlet 20, having socket 14,
and pipe 13, having hole 15, with cover 16, with or without extension pipe 13" all
substantially as set forth and shown.
