PROVISIONAL SPECIFICATION.
An Improved Sanitary Trap or Gulley for Drain or other Pipes.
I CHARLES HERBERT SANKEY of Essex Wharf, Canning Town in the County
of Essex, Manufacturer and Merchant of Bricks, Pipes, Sanitary Goods &c. do
hereby declare the nature of this invention to be as follows:-
-
An improved sanitary trap or gulley for drain and other pipes whereby all grease
or other solid matter is absolutely prevented from entering the drain or pipe and
rendered easily removable and all sewer or other noxious gases and vapours are
absolutely prevented from escaping from the drain or other pipe. The invention
consists of a vessel or cylinder either round square or of other suitable shape made
of best glazed stoneware or other material and having an overflow pipe of smaller
diameter running from the bottom of the vessel or cylinder perpendicularly on the
outside thereof and fastened to the outside or made of the saine material to a point
reaching nearly to the top of the vessel or cylinder when by a curve it enters the
drain or pipe. On the top of the curve is an air tight cap or inspection lid which
can, if required, be replaced by a ventilating pipe to carry off sewer or other gases
or vapours. Inside the vessel or cylinder is a moveable pan or bucket with
perforations or spaces round the rim or elsewhere (and a handle) made to fit the
shape of the vessel or cylinder so that all fat grease or other solid matter adhering
to the sides or getting into the vessel or cylinder is by the action of drawing up the
pan or bucket removed. The trap or gulley is provided with a moveable top or
grid of suitable shape to allow the pan or bucket to be drawn out by the handle
which top or grid is perforated so as to allow water or other liquids to enter and an
inlet with or without a nozzle can be made to the vessel or cylinder in any
size or position required. It is claimed that nothing can pass away from the trap
or gulley until the water or other liquid is on a level with the top of the overflow
pipe at the curve and then only such matter as can pass or filter through the holes
ог spaces in the pan or bucket nor can any gases or vapours escape from the drain
or pipe so long as sufficient water or liquid remains in the trap or gulley to cover
the entrance to the overflow pipe at the bottom of the trap or gulley.

COMPLETE SPECIFICATION.
An Improved Sanitary Trap or Gulley for Drain or other Pipes.
I, CHARLES HERBERT SANKEY, of Essex Wharf, Canning Town, in the
County of Essex, Manufacturer and Merchant of Bricks, Pipes, Sanitary Goods, &c.,
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 has for its object an improved form of trap or gulley for drain and.
other pipes which will under normal circumstances prevent, to a greater extent than
has hitherto usually been the case, the entrance of grease or solid matter to, and the
escape of sewer gas or other noxious gases and vapours from the drain or pipe, and
render easy the removal of the grease and solid matter collected therein.
My improved trap or gulley consists of a vessel or cylinder either round, square
or of other suitable shape made of glazed stoneware or other material and having
Price 77

page_text: an overflow pipe of smaller diameter running from the bottom of the vessel or
cylinder perpendicularly on the outside thereof and fastened to the outside, or made
of the same material to a point reaching nearly to the top of the vessel or cylinder
when by a curve it enters the drain or pipe. On the top of the curve is an air tight
cap or inspection lid which can, if required, be replaced by a ventilating pipe
to carry off sewer or other gases or vapours. Inside the vessel or cylinder is
a removable pan or bucket with perforations or spaces round the rim or elsewhere
(and a handle) made to fit the shape of the vessel or cylinder so that the greater
portion of the fat, grease or other solid matter adhering to the sides or getting into
the vessel or cylinder is removed by the action of drawing up the pan or bucket by
means of a suitable handle. The trap or gulley is provided with a movable top or
grid of suitable shape to allow the pan or bucket to be drawn out by the handle
which top or grid is perforated so as to allow water or other liquids to enter, and an
inlet with or without a nozzle can be made to the vessel or cylinder in any size or
position required.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawing which is a sectional elevation of a trap or gulley constructed according to
my invention.
-
The gulley or trap consists of a vessel a provided with a suitable cover and
grid a a² of glazed stoneware or other material and of square cylindrical or other
suitable shape having an overflow or outlet pipe extending from or nearly from
the bottom, to or nearly to the top thereof and provided at its upper end with an
air tight inspection lid c which when necessary may be replaced by a ventilating
pipe to carry off sewer or other noxious gases or vapours.
Inside the vessel a is placed a pan or bucket d perforated at e or at any other
suitable point, and having its upper edge flanged outwards to fit the vessel a so as
to prevent fluid to a great extent entering the outlet or overflow pipe b except
through the perforations e whilst acting as scraper for cleaning the sides of the
vessel a when drawn up by the aid of handle
J.
Having now particularly described and ascertained the nature of my said
'invention and in what manner the same is to be performed 1 declare that what I
claim is :-
(1.) In traps or gulleys for drain and other pipes the arrangement of the
overflow or outlet pipe substantially as and for the purpose described and
illustrated in the accompanying drawing.
(2.) In traps or gulleys for drain and other pipes a removable bucket constructed
and arranged substantially as and for the purpose described and illustrated in the
accompanying drawing.
(3.) Sanitary traps or gulleys for drain and other pipes constructed and arranged
substantially as described and illustrated in the accompanying drawing.
