PROVISIONAL SPECIFICATION.
Improvement in Drainers for Jawboxes, Troughs, and the like.
I, WILLIAM BROWNHILL SMITH of 31 Queen Street in the City of Glasgow,
Silversmith, do hereby declare the nature of this invention to be as follows:-
This invention relates to drainers such as are fitted over or constitute the outlet
orifices of sinks or jawboxes washing troughs or tubs and the like and it consists in
the provision of an auxiliary movable finely perforated drainer which is cupped or
otherwise shaped to fit loosely into the fixed drainer. This auxiliary drainer
serves the purpose of retaining solid and fibrous particles and sludge in the waste
water or liquid discharged by the outlet and is adapted to be readily lifted out
and emptied or cleaned and replaced.

COMPLETE SPECIFICATION.
Improvement in Drainers for Jawboxes, Troughs, and the like.
I, WILLIAM BROWNHILL SMITH, of 31 Queen Street, Glasgow, Lanarkshire,
Silversmith, do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement in writing reference being had to the accompanying
sheet of drawings, and to the letters and figures marked thereon, that is to say :-
My invention relates to drainers such as are fitted over or constitute the outlet
orifices of sinks or jawboxes, washing troughs, wash hand basins, or tubs, and the
like, and it consists in the provision of an auxiliary movable finely perforated
drainer which is cupped or otherwise shaped to fit loosely into the fixed drainer.
This auxiliary drainer serves the purpose of retaining solid and fibrous particles
and sludge in the waste water or liquid discharged by the outlet and is adapted to
be readily lifted out and emptied or cleaned and replaced.
Referring to these drawings.-Figure 1 is a sectional elevation of a small part of
an ordinary iron sink A, showing the outlet orifice or duct a fitted with one form
of my improved portable perforated drainers B, formed with a domed or curved-up
bottom & perforated sides bangled inwards to permit the water or liquid to pass
between it and the sides of the duct a and flange 6 for resting on the top of the
outlet orifice a and bottom of sink A, above the ordinary drainer a¹; or the
flanges may be dispensed with. This form has small projections or ears 6'
formed on it, projecting inwards for the more convenient lifting of the drainer out
to empty or clean same of the dirt, fibrous matter, or sludge retained therein and is
intended to be removed from the outlet orifice or duct a when same has to be closed
by the insertion of the ordinary plug which is not shown in the drawings. Figure 2
is a plan view and Figure 3 a perspective view of the improved drainer, the reference
letters marking the same parts as in Figure 1.
Figure 4 is a sectional elevation of a small part of the bottom of a wooden
trough or wash tub C, showing the outlet orifice or duct c fitted with another
somewhat modified form of my improved drainer B formed to fit into the upper
part of the outlet duct cover the ordinary drainer e', and to receive the plug D
which may be of any of the ordinary forms having its sides d shaped to fit into
the interior of the drainer B; or it may be formed with a flange to form the
watertight joint with the top of the outlet duct c; and the drainer B be formed
Price 8d

page_text: without flanges. The drainer B in this case is shown fitted with a wire handle b*,
swivelling on eyes 6º for conveniently lifting it out to empty and clean it of any
matter collected when in use. Instead of a handle 6 small rings could be attached
on each side of the flange or other means could be adopted for effecting the
purpose of lifting out the improved drainer. In this form the sides bare
perforated and curved inwards and the bottom & perforated and domed upwards
to allow of the free passage of the water or liquid. Figure 5 is a plan view
of the drainer B shown in Figure 4, the same letters marking the same parts as
in that figure.
Figures 6 and 7 are a sectional view through the centre and a plan respectively
of a simplified form of drainer consisting of a perforated disc B domed up and
slightly dished up or edged all round at o¹, and having a ring in the centre for
lifting it out of the outlet duct, in which it would be placed over the ordinary
drainer a¹.
These improved drainers would be formed of brass, zinc, or other suitable metal
and could be somewhat modified in form without departing from the special feature
of the invention, and could be applied to all kinds of sinks, troughs, wash-hand
basins, tubs, and articles and utensils of a like nature.
.
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 :-
The construction and use of portable perforated drainers for use in the outlet
orifices or ducts of sinks, troughs, basins, tubs, and the like, substantially as,
and for the advantages and purposes herein described and illustrated by the
accompanying drawings.
