PROVISIONAL SPECIFICATION.
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 accumulation
of soap and dirt which overflow and the upper ends of waste pipes assume after use
and to facilitate the cleansing of the same.
My invention consists in dispensing with the ordinary plug and overflow pipe and
forming a sliding pipe which performs the functions of waste pipe, overflow pipe and
plug. I 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 an inner
tube of uniform, taper, or varying diameters which may be provided with india rubber
or other 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. The inner
tube may be provided with a detachable or other grid and a loop or other means of
elevating it.
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 tuhe. Owing to this position 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, & the height of
the lift may be limited by stops. The inner tube maintains itself in its raised position
by pressure of the washer or other suitable arrangement. The inner tube then
prevents the water in the basin passing to waste, and also acts as an overflow pipe
should the water be allowed to continue to flow. In order to empty the basin the
stand-pipe is pushed down, & may be caused to be released immediately and fall into
its normal position, so as to permit the escape of water from the basin.
When it is intended to adapt my invention to deep basins or baths then I may
make the inner tube to slide in a telescopic manner so as to cause it to work in a less
space than if made in one piece. The tube may also be flexible. I may form grooves
or corrugations on either or both tubes or provide both or either with a slide or slides,
stop or stops.
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.

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 inven-
tion 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 cleansing of the same.
My invention consists in dispensing with the ordinary plug and overflow pipe and
forming a sliding pipe which performs the functions of wastepipe over-flow pipe and
plug. I 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 an inner tube of
uniform, taper or varying diameters which may be provided with india-rubber or
other 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. The inner tube may be
provided at the top with a detachable or other grid and a loop or other means of
elevating it.
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 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 maintains itself in its raised position by pressure of the washer or other
suitable arrangement. The inner tube then prevents the water in the basin passing to
waste, and also acts as an overflow pipe should the water be allowed to continue to
flow. In order to empty the basin the stand-pipe is pushed down, and may be caused
to be released immediately and fall into its normal position so as to permit the escape
of water from the basin.
When it is intended to adapt my invention to deep basins or baths then I may make
the inner tube to slide in a telescopic manner so as to cause it to work in a less space
than if made in one piece. The tube may also be flexible. I may form grooves or
corrugations on either or both tubes or provide both or either with a slide or slides,
stop or stops.
"
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.
In order that my invention may be clearly understood I have annexed hereto a sheet
of drawings marked with figures and letters of reference corresponding with those of
the following description thereof.
Fig. 1 is a sectional elevation of the bottom of an earthenware lavatory basin made
according to my invention and
Fig. 2 is a plan of the inner tube hereafter described.
a is the outer tube shewn made of varying diameter, that is made with the upper
part a 1 reduced and slightly tapered. The part a 1 is preferably made separate and
fixed by the screwed plate or ring a 2.
bis the inner tube provided with the washer 61, and with a perforated cap at the
upper end forming a grid 62, through which water can escape into the tube, the said

page_text: cap b 2 being made with projections 63 (see Fig. 2) by which it can be lifted, when
desired, into the position shewn by the full lines on the drawing, the washer b1
fitting tightly into the part a 1 of the outer tube a, the tube b in this position acting
as an overflow pipe as well as a plug. By forming the part a 1 of the outer tube a of
reduced diameter and coned as shewn, the washer 61 and inner tube b are released
instantly when the tube is pushed downwards and the latter will fall until stopped by
the shoulder or projection b* falling upon the bush a* as seen by the dotted lines on
Fig. 1.
The tube 6 then becomes part of the waste pipe. By applying suitable annular
wipers or brushes just below the washer, the pipe a can be cleansed by the pipe b as it
is moved alternately up and down.
Fig. 3 shows another way in which the inner tube may be used; in this case the
outer tube a is of varying diameter and made at the upper end with an internal flange
or annular projection a 3, upon which when the inner tube b is raised the washer b 11
can rest, but sufficient pressure can be put upon the inner tube by the hand to
force the washer 11 through the reduced opening formed by the internal flange.
or annular projection a 3, and cause it to fall to the bottom of the tube (see dotted
lines).
Fig. 4 shews another way of applying the inner tube. In this case the two-
tubes a and b fit water tight (or may be made to do so by a washer if required); the
inner tube can slide in the outer tube a into the raised position preventing the
escape of water from the bottom of the vessel, but if lowered the open part 2 of
the said tube b will come to an enlarged part a 4 of the outer tube a in communication
with the basin or vessel by a grid c and thus the inner tube will become a part of the
waste pipe.
A projection b 4 may be fixed on the tube b and can pass through a slot c 1 in the
grid c, and on the tube b being turned slightly round the tube b will be held in the
raised position if the friction of contact between the two tubes a and b is not sufficient
to sustain it.
I do not confine myself to the exact details herein before set forth and illustrated, as
my invention may be applied in many forms, so long as the chief feature thereof is.
retained, that is to say a tube or pipe so fitted to the basin or vessel that the upper
end of the said tube or pipe (where it is open or perforated) may be raised in order
that the said tube shall then act as overflow and plug, and lowered when it is desired
to act as a waste pipe.
By this means the flushing of the surface of the said tube or pipe is effected each
time the vessel is emptied of water.
I am aware that a tubular stopper has been used to perform the functions of an
overflow pipe and a plug, such stopper being applied from above to the upper end
of the waste pipe, but in this case the stopper was raised or removed from the waste.
pipe while emptying the basin or vessel.
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 :-
A tube or pipe fitted to a lavatory basin bath or the like so as to perform the
functions of waste pipe overflow pipe and plug, the raising of the tube or pipe
closing the outlet and forming the overflow and the lowering of the said tube or
pipe opening the outlet and allowing of the emptying of the basin bath or
the like.
