Improvements in Lavatory Basins, Baths, and the like.
FREDERICK CHARLES LYNDE Civil and Sanitary Engineer 25 Cross Street
Manchester, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to obviate the foul condition caused by accumu-
lation of soap and dirt which overflow pipes and the upper ends of wastepipes
assume, after use and to facilitate the cleaning of the same. My invention
consists in the dispensing with the ordinary plug and overflow pipe and forming a
sliding pipe which performs the functions of wastepipe, overflow pipe and plug.
I may also dispense with a permanent stand-pipe within the basin.
I will now describe one method of carrying my invention into effect.
In a convenient position in the basin, I form an outlet hole fitted with a suitable
outlet pipe of uniform, taper, or varying diameters. Within this pipe, I fit or
place an inner tube of uniform, taper, or varying diameters which may be provided
with india rubber, or other valve which may be provided with regulating apparatus
such as a screw or lever, washer or washers and slots or projections to engage with
slots and projections upon the interior of the outer tube forming a stop or stops or
for retaining the inner tube in position. The inner tube may be provided with a
detachable or other grid and a loop or handle or other means of elevating it, and
its upper end may, when the inner tube is in its lowest position stand either level or
below, or may project above the outlet hole. The annular space between the two
tubes being due to the difference of diameters, should the tubes not be made a
sliding fit, may be utilised for and to increase the outflow from the basin and may
be covered with a grid.
I will now explain the action of the apparatus.-
Assuming the basin to be empty, the inner tube would be in its normal position
viz. at the lowest point within the outer tube. Owing to this position, the outlet
is caused to be open and the basin has emptied itself. In order to allow the basin
to be filled, the inner tube is raised by lifting it by means of a handle, ring or
other suitable arrangement, and the height of the lift may be limited by stops.
The inner tube may maintain itself in its raised position by pressure of the valve
or washer or other suitable arrangement. The valve and inner tube then prevent
the water in the basin passing to waste, and the inner tube also acts as an overflow
pipe, should the water be allowed to continue to flow. In order to empty the basin
by allowing the water to pass to waste, the inner pipe is pushed down, and may be
caused to be released immediately and fall into its normal position, and be arrested
by a cushion of india rubber or a washer of india rubber slotted so as to facilitate
the flow of water to waste. The releasing of the inner tube may be effected by
means of a taper portion within the outer tube which both serves to retain the inner
tube when up and to release it when pushed down. The passage of the water may
be either entirely down the inner tube and not outside it, or it may be both inside
and outside the inner tube.
My invention may be adapted to deep basins or baths by making the inner tube
in sections to slide in a telescopic mauner or loosely with cone joint as before
described or other suitable joint and retainer so as to cause it to work in a less

page_text: space than if made in one piece. The tubes may be flexible or partly so. I may
form grooves or corrugations longitudinally or round the tube or tubes.
In order to empty the basin the tube is pressed down and the valve is released
and the water enabled to flow to waste.
The inner tube is so made that it can be readily detached from the outer tube
and cleaned and the grid can be detached from the inner tube.
In order to cleanse the tube surfaces the, action of the raising and lowering
of the inner tube may be utilised for this purpose with properly constructed
washers or wipers.
By moving the inner tube in a circular direction the valve or washer may be
tightened or the same result may be obtained by a lever or other suitable
arrangement.

Improvements in Lavatory Basins, Baths, and the like.
I FREDERICK CHARLES LYNDE, Civil and Sanitary Engineer, of 25 Cross
Street, Manchester, in the County of Lancaster, 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 obviate the foul condition, caused by
accumulation of soap and dirt, which overflow pipes and the upper ends of waste-
pipes assume after use, and to facilitate the cleaning of the same.
My invention consists in dispensing with the ordinary plug and overflow pipe,
and forming a specially fitted sliding pipe which performs the functions of waste-
pipe, overflow pipe and plug, as hereafter described.
I may also dispense with a permanent stand-pipe within the basin.
I will now describe one method of carrying my invention into effect. In a
convenient position in the basin, 1 form an outlet hole made or fitted with a suitable
outlet pipe of uniform, taper, or varying diameters.
Within this pipe, I fit or place an inner tube of uniform taper or varying
diameters, which may be provided with india rubber, or other valve which may be
provided with regulating apparatus such as a screw or lever, washer or washers and
slots or projections to engage with slots and projections upon the interior of the outer
tube forming a stop or stops or for retaining the inner tube in position, or external
stops may be provided for this purpose. The inner tube may be provided with a
detachable or other grid and a loop or handle or other means of elevating it, and
its upper end may, when the inner tube is in its lowest position stand either level or
below, or may project above the outlet hole. The annular space between the two
tubes being due to the difference of diameters, the tubes not being made a sliding
fit, may be utilized for, and to increase the outflow from the basin and may be
covered with a grid, or the tube may be utilized to increase the outflow from the
basin if the grid or top of the inner tube is level with the bottom of the basin
when at its lowest position.
I will now explain the action of the apparatus:-
Assuming the basin to be empty, the inner tube would be in its normal position,
viz. at the lowest point within the outer tube. Owing to this position, the outlet
is caused to be open and the basin has emptied itself. In order to allow the basin
to be filled, the inner tube is raised by lifting it by means of a handle, ring or
other suitable arrangement, and the height of the lift may be limited by stops.

page_text: The inner tube may maintain itself in its raised position by pressure of the valve
or washer or other suitable arrangement. The valve and inner tube then prevent
the water in the basin passing to waste, and the inner tube also acts as an overflow
pipe, should the water be allowed to continue to flow. In order to empty the basin
by allowing the water to pass to waste, the inner pipe is pushed down, and may be
caused to be released immediately and fall into its normal position, and be arrested
by a cushion of india rubber or a washer of india rubber which may be slotted so
as to facilitate the flow of water to waste.
The releasing of the inner tube may be effected by means of a taper portion or a
collar within the outer tube which both serves to retain the inner tube when up and
to release it when pushed down. The passage of the water is both inside and
outside the inner tube, thereby flushing both tubes every time that the basin or
vessel is emptied, and for this purpose the inner tube inay be held 'suspended in the
outer tube when in its lowest position by means of a suitable stop which, may also
prevent it from being raised too high.
My invention may be adapted to deep basins or baths by making the inner tube
in sections to slide in a telescopic manner or loosely with cone joint as before
described or other suitable joint and retainer so as to cause it to work in a less
space than if made in one piece.. The tubes may be flexible or partly so, I may
form grooves or corrugations longitudinally or round the tube or tubes.
In order to empty the basin the tube is pressed down and the valve is released
and the water enabled to flow to waste.
The inner tube is so made that it can be readily detached from the outer tube
and cleaned, and the grid can be detached from the inner tube. In order to cleanse
the tube surfaces the action of the raising and lowering of the inner tube may be
utilized for this purpose with properly constructed washers or wipers.
By moving the inner tube in a circular direction the valve or washer may be
tightened or the same result may be obtained by a lever or other suitable
arrangement.
In order that my invention may be clearly understood I have annexed hereto two
sheets of drawings of which the following is a description, and which illustrate
methods of carrying my invention into practical effect.
On Sheet Fig. 1 is a transverse section through the outlet of a lavatory basin
to which my improvements have been applied.
Fig. 2 is a similar view of a similar construction but the outer tube is in this
view formed with the basin and in Fig. 1 the said tube is separate and fitted to the
outlet of the basin.
On Sheet 2 Fig. 3 is a transverse section taken at right angles to the plane of
section of Figs. I and 2 shewing a further modification hereafter referred to.
a is the bottom of the basin. "b is an outer tube formed or fitted at the outlet
thereof, which is preferably formed in a recess a at the back of the basin, c is the
inner tube made with an opeuing e+, or a grid or openings e 1, at the top and made
of metal as seen at Fig. 1 or earthenware as seen at Fig. 2.
When the basin is to be filled, the tube e is raised by the handle e 2 until the
valve c3 which is preferably made of india rubber of the form shewn in section at
Figs. 1 and 2, fits water tight in the seating formed by the reduction in diameter,
or shoulder b1, at the upper end of the tube b, and the water cau rise in the basin
to the level shown at X, X, and the tube e will then become an overflow pipe, as
well as a plug. In these cases the valve c3 is held in place by the pressure of the
same in its seating & 1.
The handle e2 is shewn sliding in a socket d preferably made of india rubber
fitted in the basin a forming a stop when the tube c is lowered to retain it in the
position shewn dotted on the drawings.
The water can then flow around the valve c 3 and also in part through the tube c
which becomes in part a waste pipe and thus both tubes are flushed every time the
basin a is emptied.
isa arid covering the unner end of the tube b

page_text: Fig. 3 shews another form of valve c4 and seating 61 held up to retain the water
by the lever fand weight 1 and lowered by pulling forward the lever f into the
.-dotted position..
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 :-
A tube applied to the outlet of a lavatory basin bath or the like, and provided
with a valve or its equivalent, so that the raising of the tube shall actuate the
valve and cause the vessel to retain water, the tube then forming an overflow pipe,
and the lowering of the said tube shall cause the water to be released, the outlet
being of such form or diameter that the water can escape both inside and outside
the said tube, substantially as hereinbefore described.
