page_text: I, WILLIAM HENRY WITHINGTON of 69 Halston Street Hulme in the County of
Lancaster Sanitary 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:-
This Invention relates to outlets for the discharge of waste waters from sinks
slop-stones troughs and similar articles and has for its object the production of an
outlet that may be readily and securely applied without the necessity for being
run in with molten lead and which may also if required be removed without risk
of injury.
For the purpose of my invention I cast a short length of tube with or without a
flange at one end and with a screw thread commencing at a distance from the flange
or upper end of the tube regulated by the thickness of the bottom of the sink or
trough or the part through which the outlet has to be secured. I also cast or other-
wise form a nut having an internal screw thread capable of engaging with the screw
thread upon the tube. If the nut is cast it will be convenient to cast one thread
only. In applying or securing the short length of tube or nozzle the upper part or
the part under the flange and between the flange and screw thread may be paid
over with white lead or other suitable putty or with Portland or other suitable
cement the hole in the sink or trough being also lined or coated therewith; the
tube is then passed through the hole and the nut is screwed home with or without
the intervention of a washer or washers. In some cases however the joint between
the outlet and the sink or trough may be made by lead indiarubber or similar
washer or washers alone or in combination with the herein before described putty
or cement. The short tube may be dropped into or secured to a lead or other
outfall pipe but when the outlet has to pass through a wall I prefer to enter the
bottom of the short tube into the upper orifice of an iron pipe having external fangs
lugs or projections cast or formed thereon in which case the irregularities on the
surface of the pipe tend to fix it in the wall.
And in order that this my said invention may be more readily understood and
carried into practical effect I have hereunto appended a sheet of drawings having
the various similar parts or details in each of the Figures thereon indicated by
similar letters and reference being hereinafter had thereto.
Fig. 1 represents, in vertical section one form of the outlet constructed according
to these Improvements and applied to an ordinary scullery sink or slop-stone.

Fig. 2 shows on a larger scale an elevation or side view of; a modified form of the
short tube or nozzle and nut.
A is the short length of tube or nozzle; B is the flange which may be omitted
when the upper part of the tube is coned or enlarged; C is the screw thread; D is
the nut; E is the sink or slopstone; F is a wall; G is the outfall pipe passing
through the wall; H H are the lugs or projections on G, I is the putty or cement
and K is a gully or sough over which the outlet terminates.
The nozzle A may be straight as shown in fig. 2 or it may be cranked as in fig. 1
or be otherwise suitably bent or curved. The outfall pipe G also may be straight
as represented in fig. 1 or it may be bent or curved as required and it will generally
be found convenient to have the nozzle A or the pipe G or both of them bent
cranked or curved as it rarely happens that the point of delivery for the waste
water is immediately below the sink or trough.
A grid L may be cast within or fitted into the upper part of the nozzle A to
prevent obstruction from the passage thereinto of solid matter.
The screw thread may be cast upon the short tube A by known means well
understood by pattern makers and founders, and the process need not therefore be
described, moreover, an equivalent arrangement such as a "snail" joint, wedges or
inclined planes may be substituted therefor.
I am aware that a somewhat similarly constructed nozzle has been heretofore
employed for cisterns, but such nozzles have been constructed of brass, wrought iron
or similar metal with cut screw threads and they have not to the best of my belief
been applied to sinks, slopstones and the like.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is :-
(1) As an outlet for a sink, slopstone, trough, or like article the combination of
the nozzle A provided with a screw thread and nut or equivalent device, with
the straight or bent outfall pipe G, substantially as hereinbefore set forth and
described.
(2) A nozzle constructed to form the outlet or part of the outlet of a sink slop-
stone trough or the like article and consisting of a straight or bent tube provided
at its upper end with a flange or enlargement and having formed or cast thereon a
screw thread or an inclined plane or planes; together with a nut or equivalent
device for closing the joint between the nozzle and the sink or trough, substantially
as herein before described.
