Improvements in Gullies for Receiving the Discharge from Baths,
Sinks, and the like.
I, WILLIAM SYKES of 18 New Bridge Street Blackfriars, in the County of
London, Civil 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 :-
My invention relates to improvements in disconnecting slippers used for taking
away waste from baths sinks &c. and also to receive stack pipes and other waste
pipes. Hitherto it has been customary to discharge these over a gulley; which
has been found to cause splashing and the deposit of grease and other offensive
matter, which gives rise to a great nuisance. It is moreover customary now for
waste pipes to discharge at least eighteen inches from the gulley so as to prevent any
offensive gases that may be given off from the gulley ascending up the various
shafts and escaping into the dwelling.
My improved disconnecting slipper consists of three distinct parts. Fig. 1.
represents a section taken through the centre of the respective parts. (1) Fig. 1. is
a P trap. (2) Fig. 1. represents the body of the slipper and 3. Fig. 1 shows the
respective intakes. The trap shown at (1) Fig. 1. is what is known as a P trap,
an Strap may be used with equal advantage, such traps however form no part of
my invention but are used in conjunction with the parts 2. and 3. which I now
proceed to more fully describe.
It will be observed from Fig. 1. that 2. represents the body of the slipper, it is
oblong in shape the top is fitted with a grating (4) which admits fresh air to enter,
and foul gases to escape being also fixed at the level of the yard or causeway it
receives the surface water and in this sense serves the twofold object of a dis-
connector and gulley. I preferably make the side (5) Fig. 2. next the building
straight or perpendicular so as to conform better to the wall, but the other side (6)
Fig. 2. is preferably made sloping so as to increase the surface area of the grating
at the top. At one end I form a socket (7) Fig. 1. and at the other I form a bull
nosed outlet (8) Fig. 1. which fits in the socket of the P trap (1) Fig. 1. thus
allowing the trap to be conveniently turned in any position to suit the direction of
the drain. I preferably form the invert in the form of a semi-circle (9) Fig. 2.
thus confining the liquid to as small a surface as possible which prevents the fouling
of the slipper. The intakes 3. Fig. 1. are made in various forms to suit circumstances,
thus if there are three waste pipes the form (3) Fig. 1 is used, if only two Fig.
is used, and if one Fig. 5. is used, the socket (7) Fig. 1. admits of any form of
intake being inserted and the two are substantially connected together by means
of a cement joint 10 Fig. 1.
1 separate each intake by a division or diaphram (11) Fig. 1. curved as shown
which throws the liquid forward thus preventing the deposit of grease and other
matter which would occur if discharged in a vertical direction on to the floor of the
intake.
Fig. 3 is a plan showing the respective parts.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be formed I declare that what I
claim is.

page_text: respectively with a rebate to receive grating with outlet bullnosed bend attached,
and socketted inlet substantially as herein described and shown for the purpose
stated.
2. Interchangeable intakes having curved diaphragms or divisions attached
substantially as herein described and shown.
3. An improved disconnecting slipper with interchangeable intakes to be used in
connection with an S or P trap substantially as herein described and shown.
