page_text: I ROBERT LOWE of No. 11 Dagmar Terrace, Prince of Wales Road, Gosport
Architect and Surveyor, do hereby declare the nature of this invention to be as
follows:-
,
My invention has for its object the providing of a combined sink pipe and trap
whereby all noxious vapours are arrested and prevented from passing into the interior
of a building.
The device or appliance according to my invention comprises a trap formed of any
suitable material but preferably of glazed or enamelled pottery or earthenware fitted at
right angles to the wall of the house and divided into three chambers one of the
partitions of which is somewhat longer than the other. From the centre chamber of
the trap and forming part thereof extends a vertical pipe terminating in a channelled
collar into which takes or dips a short length of pipe secured to or forming part of
the under side of the sink; a luting of cement or equivalent being introduced in the
channel of the collar to ensure a tight joint. A discharge pipe forming part of the
trap extends from the chamber nearest the wall of the building through which it
passes in a downward direction, the extremity thereof taking into a branch pipe con-
nected with the sewer or entering direct into the sewer as may be most convenient.
The outer chamber terminates in a channelled collar, into which collar fits a suitable
cap or lid having a fillet formed thereon which latter dips into a suitable luting,
provided in the channel aforesaid. Said luting being of such a nature as to allow of
the ready removal of the cap without interfering with the efficiency of the sealing.
It will be obvious that a combined sink pipe and trap as above described embraces
many advantages over those ordinarily constructed and in use, inasmuch as the trap
and pipes being made without joints, leakage is impossible, and being moulded in
glazed or enamelled earthenware, there is no corrosion or other chemical action, hence
cleanliness is assured at all times.
Dated this 11th day of February 1888.

page_text: I, ROBERT LOWE of No. 11 Dagmar Terrace, Prince of Wales Road, Gosport,
Architect and Surveyor 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 the providing of a combined sink pipe and trap
whereby all noxious vapours are arrested and prevented from passing into the interior
of a building.
In order that my invention may be the better understood, I have appended the
accompanying sheet of drawings in which Figure 1 is a side sectional elevational
view of the combined sink pipe and trap according to my invention. Figure 2 is a
front elevational view, and Figure 4 is a plan of same. Figure 3 is a sectional
elevation of the vertical pipe, showing a packed joint.
The device or appliance according to my invention comprises a trap A formed of
any suitable material, but preferably of glazed or enamelled pottery or earthenware,
fitted at right angles to the wall of the house, and divided into three chambers a, a¹, all,
one of the partitions of which is somewhat longer than the other . From the
centre chamber a¹ of the trap A and forming part thereof, extends a vertical pipe B¹
terminating at its upper extremity in a channelled or flanged collar C into which
takes or dips a short length of pipe c secured to or forming part of the underside of the
sink D; the short length of pipe c being secured to the pipe B¹ by the employment of a
suitable cement, to ensure a tight joint. A discharge pipe d forming part of the trap
extends from the chamber a, and inclining downwards, passes through the wall to the
exterior of the building, the extremity of said discharge pipe d taking into a branch
pipe connected with the sewer, or entering direct into the sewer, or, if desired
the discharge pipe may extend a little beyond the exterior surface of the wall of the
building, the contents of the trap being discharged into a sink provided for the
purpose. The outer chamber a terminates in a channelled or flanged collar e,
arranged horizontally, in which takes a suitable cap or lid E having-when arranged
to fit into the channel or recess-a fillet formed thereon, which dips into a suitable
luting or cement; said luting or cement being of such a nature as to allow of the
ready removal of the cap or lid without interfering with the efficiency of the sealing.
The pipe B may be of any desired length, and I may under some circumstances
lengthen the same by the insertion of a short pipe B1, the flanged collar of which is
of larger internal diameter than the external diameter of the pipe B', thus leaving
space for the insertion therebetween of a suitable packing g so as to ensure a tight
joint.
As a modification of the foregoing, I may form the trap of the same diameter as
the vertical pipe B and discharge pipe d, and, instead of the outer chamber all being
vertical and parallel with the pipe B, as shown, I may arrange said chamber a" at
any suitable angle relatively to the pipe B.

page_text: The combined sink pipe and trap above described according to my invention,
possesses important advantages over those ordinarily constructed and in use, inasmuch
as being formed without joints, leakage is impossible and being moulded in glazed or
enamelled earthenware it is uneffected by corrosive or other chemical action, hence
perfect cleanliness is assured.
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 :
The combined scullery sink pipe and trap substantially as and for the purposes
herein described and illustrated in the accompanying drawings.
