PROVISIONAL SPECIFICATION.
An Improved Appliance for Use in connection with Drain, Sink,
and other Pipes.
I, JAMES ARTHUR KERSHAW of 7, Norwich Street, Rochdale, Strap Maker,
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to prevent the uprising of effluvia from drain,
sink, and other pipes, and in carrying my invention into effect I proceed in or in
about the following manner, that is to say, I provide a comparatively short tube
of circular, square or other cross-section according to the cross-section of the pipe
with which it is to be used, and of such diameter as will permit of its easy insertion
into the pipe into which it is to be employed. The upper end of this short pipe is
provided with a grating and with a flange the latter for the purpose of preventing
the appliance slipping down the pipe. Centrally or more or less so across the
lower end of the appliance I hinge a flap door, one half of which is weighted so as
to keep the other half in contact with and so close the other half. The weighted
half of the door is covered over in such a mauner as to prevent anything falling
on it from above, but at the same time so as not to prevent the upward movement
of the weighted half, when anything falls on the unweighted half. Assuming this
appliance to have been inserted into, and its flange resting on, the upper part of
the drain, or sink or other pipe with which it is to be used, the weighted flap door
at the end of the appliance will prevent the uprising of any effluvia. At the same
time when any fluid is thrown on the grating of this appliance, it will pass down it
and force open the unweighted half of the flap door and as soon as the fluid has
passed, the weighted half of the door will return the unweighted half to its normal
position and close the end of the appliance.
The appliance may be made of any suitable material.

COMPLETE SPECIFICATION.
An Improved Appliance for Use in connection with Drain, Sink,
and other Pipes.
I, JAMES ARTHUR KERSHAW of 7, Norwich Street, Rochdale 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:-
The object of my invention is to prevent the uprising of effluvia from drain,
sink and other pipes, and in carrying my invention into effect I proceed in or in
about the following manner, that is to say, I provide a comparatively short tube
of circular, square or other cross section according to the cross section of the pipe
with which it is to be used and of such diameter as will permit of its easy insertion
into the pipe with which it is to be employed. The upper end of this short pipe

page_text: is provided with a grating and with a flange the latter for the purpose of pre-
venting the appliance slipping down the tube. Centrally or more or less so across
the lower end of the appliance I hinge a flap-door, one half of which is weighted
so as to keep the other half in contact with and so close the end of the pipe. The
weighted half of the door is covered over in such manner as to prevent anything
falling ou it from above, but at the same time so as not to prevent the upward
movement of the weighted half when anything falls on the unweighted half.
Assuming the appliance to have been inserted into, with its flange resting on, the
upper part of the drain, sink or other pipe with which it is to be used, the
weighted flap door at the end of the appliance will prevent the uprising of any
effluvia. At the same time when any fluid is thrown on the grating of the
appliance it will pass down it and force open the unweighted half of the Hap door
and as soon as the fluid has passed, the weighted half of the door will return the
unweighted half to its normal position and close the end of the appliance. The
appliance may be made of metal, pottery, glass or any other suitable material, or
materials, In order to more clearly explain ny invention I make reference to the
accompanying sheet of drawings in which Fig. 1 is a longitudinal section and
Fig. 2 a plan of one of my improved appliances. a is the short pipe, 6 the flanged
grating the flap door hinged at d and weighted at e. (The dotted lines show
the door open and the full lines the door when closed.) fis the partition across
the pipe to cover the weighted half of the flap door, but at the same time allow the
end to tip up as shown.
I do not confine myself to the precise shapes, configuration, relative proportions
or disposition of parts as described in the above specification and exemplified in
the accompanying drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An improved appliance for use in connection with drain, sink and other pipes
and consisting essentially of a short pipe or equivalent having at its upper end a
grating and at its lower end a hinged flap door weighted at one edge and so
arranged that when pressure is removed from the unweighted portion the weighted
edge will cause the unweighted portion to close the end of the pipe and prevent the
uprising of effluvia, the whole substantially as described in the above specification
and exemplified in the accompanying drawings.
2. An improved appliance for use in connection with drain, sink and pipes, the
said appliance being constructed and operating substantially as described in the
above specification and exemplified in the accompanying drawings.
Dated this 5th day of August 1896.
