Improvements in Fittings for Lavatories, Baths, and Sinks, and in
Valves and Traps for the same.
I, JAMES GEORGE STIDDER, of Petersham Lodge, New Malden, in the County
of Surrey, Engineer do hereby declare the nature of my said invention to be as
follows:-
:-
The object of my invention is to fit lavatories, baths, and sinks, with improved
valves and traps, whereby the foul water may be readily discharged, and effluvia
arising therefrom may be effectually prevented from returning or emanating from
the drain.
In carrying out my invention, I fit a plug valve to the bottom outlet of the
basin. This plug valve opens into an outflow pipe of larger diameter than the
valve, secured to the basin with a fluid-tight joint. The overflow from the basin
also runs into this pipe in the usual manner. On one side of the outflow pipe a
lever or trigger is mounted in a fluid-tight bearing. The inner end of this lever
engages in a hole or slot formed in the stem of the plug. The lever is so
weighted that, when the valve is raised, it is supported in that position, thus
allowing the foul water to flow away. The lever may be raised and lowered by
the application of the hand to the outer end of the lever; and the plug may be
supported in a raised position by means of shifting weights attached to the lever,
or by a weighted vertical lever attached to the spindle, or by a spring acting
upon a cam, or by a toggle-jointed lever, or analogous contrivance.
The supply to lavatories &c., is so made and constructed, that the whole of the
interior working parts of the valve can be taken out at the top of the slab, and
the water shut off during repairs, or when removing grit or other matter from off
the seat of valve, without the aid of stop cocks or plugging the pipes when under
pressure.
I run the waste from the outlet, and from baths, sinks, and other sanitary and
other appliances, into a slipper sink, with a combined trap, and one, two, or more
shoes combined in one, and supported by or connected with a cast iron ventilating
grating, which extends (in parts) the whole length of the slipper sink. The
slipper sink has a trap at one end, preferably having a two inch dip, the outlet
leading to a bend, the bend being formed at any angle to suit the rim of the drains.
The entrance to the trap is covered with a curved iron grating, set at a consider-
able inclination, so as to secure a large area of interception, and throw solid
matters back out of the way of the running fluids. At the trap end of the slipper
I fit a socketed bend to receive the end of a down water pipe, which leaves the
inlet open inside the slipper for ventilation.
I also make a square box-shape receiver, with a hole in the bottom, and a
projecting rim to fit into a trap. One side of the box is shaped to receive the
bottom of a rain water pipe, with a grating to fit in the top and round the pipe,
the end of the pipe being left free and open for ventilation.

Improvements in Fittings for Lavatories, Baths, and Sinks, and in
Valves and Traps for the same.
I, JAMES GEORGE STIDDER, of Petersham Lodge, New Malden, in the County
of Surrey, Engineer, do hereby declare the nature of my said 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 fit lavatories, baths, and sinks, with improved
valves and traps, whereby the foul water may be readily discharged, and effluvia
arising therefrom may be effectually prevented from returning or emanating from
the drain.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts..
Fig. 1 is a sectional elevation of my improved lavatory basin.
Fig. 2 is a separate sectional view of the valve arrangement, drawn to a larger
scale.
Fig. 3 is a plan of one form of admission valve.
Fig. 4 shows another arrangement for actuating the plug valve.
Fig. 5 shows an improved form of screw valve, for the supply of lavatories,
sinks &c.
Fig. 6 is a section on the line 1-2 of Fig. 5.
Fig. 7 shows an improved bull nose waste water slipper, with trap combined.
Fig. 8 is a plan of the same.
Fig. 9 shows a form of bull nose shoe for receiving the water at the lower ends
of rain water pipes.
Fig. 10 is a plan of the same.
a is a lavatory basin, formed of strong Stourbridge clay or Staffordshire pottery.
bis the service pipe, which may be fitted with the plug valve shown in Fig. 3,
or the screw tap Fig. 5 or any other suitable tap or valve. The pipe b is sustained
by a longitudinal angle bar, which not only sustains but also protects the pipe
from damage. c is the supply nozzle. d is the overflow pipe, so formed that when
the water rises above the height shown in Fig. 1, the overflow can run away
without raising the plug valve e. The plug e is raised, for emptying the basin,
by means of the lever f. One end of this lever is pivoted to the bell crank lever g.
The other end passes through a slot in the casing. f¹ is a notch formed to retain
the lever, when drawn out, by engaging the lip of the casing, whereby the plug e
is kept open, if desired. Another method of keeping the plug open is shown in
Fig. 4, in which the outer arm of the bell-crank lever g' is fitted with a weight k
supported by rollers m. When the outer arm of the lever g' is lowered to open
the valve e, the weight k travels to the position on the lever, and thus retains
the valve open, until the lever g' is again raised by hand. n is the waste water
pipe.
The supply tap shown in Fig. 3 is worked by means of the button o. Upon
pressing this button inwards the water issues through the nozzle c to the basin.
The body ss of the screw tap shown in Fig. 5, is made in one casting. t is a
plug, bored and tapped to receive the screw-threaded spindle u. A passage is
cored in the plug, at the lower end of which the valve seating is formed. p is a
disc screwed to the spindle u, and fitted with a rubber ring in an annular groove.
vis a screw cap which holds the working parts in position. The whole of the
interior working parts of the valve can be taken out for cleaning or repair after
removal of the cap v. is a plate fitted to the lower part of the casting for
securing the tap in position by means of screws, as also shown in Fig. 6.
I run the waste from the outlet pipe n, and from baths, sinks, and sanitary and

page_text: other appliances, into a bull nose waste water slipper sink, of the form shown in
Figs. 7 and 8; Fig. 7 being a sectional elevation and Fig. 8 a plan. w is a cast
iron ventilating grating, covering nearly the whole length of the slipper sink. w' is
a trap, preferably having a two-inch dip, the outlet leading to a bend, which bend
is formed to any angle to suit the run of the drain. The entrance to the trap is
covered by a curved iron grating w³, set at a considerable inclination, so as to
secure a large area of interception, and throw solid matters back out of the way of
the running fluids. to illustrate my improved method of fitting two or more
pipes to one slipper sink, for draining sinks and other appliances.
Fig. 9 is a vertical section and Fig. 10 a plan, showing my improved method of
forming a bull nose shoe for receiving the water from the lower ends of rain
water pipes, so as to bring the water pipe plumb down the wall. Fig. 10 shows
the recess in the wall, which accommodates the corresponding projection in the
shoe, a straight pipe being used instead of a pipe with a curved end. x is a
rectangular receiver, having a projecting rim to support the receiver. y is the
rain water pipe, and z is the grating which fits the receiver and also the pipe.
The end of the pipe y is thus left free and open for ventilation.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
The several and respective improvements in fittings for lavatories, baths and
sinks, and in valves and traps for the same, substantially as herein before described
and illustrated by the drawings.
