PROVISIONAL SPECIFICATION.
Improvements in the Construction of Water-closets, and in Flushing,
Trapping, and Supplying the same with Water.
I, JAMES GEORGE STIDDER, of 66 Waddon Old Road, Croydon, in the
County of Surrey, Sanitary Engineer, do hereby declare the nature of my said
invention to be as follows
The object of my invention is to effect improvements in the construction of water
closets, and in fitting the same with valves and other appliances, for the purpose
of rendering the action of the valves noiseless; preventing the return of noxious
gases; securing an abundant flush, and preventing the waste of water.
In applying my improvements to valve closet pans, I form the rim in such a
manner that a complete "all round" flush is secured, an opening being formed
at the back of one portion of the rim, leading to a trap, the overflow edge of
the trap being at such a height as to regulate the height of water remaining in
the pan after the flushing of the pan has been effected.
I fit the stuffing box to the sunk cup with " woodite " or other packing,
through which the rod to the lever passes, to render it air-tight. The fulcrum
of the lever is adjustably pivoted to a spring, which allows the fulcrum to
accommodate itself to the motions of the lever. A stud on the lever works in
a slotted lever or cam attached to the valve bracket, the slot being so formed that,
when the valve is closed, the stud locks the valve in that position.
A lug
attached to the lever rod is fitted with a rubber roller in a fork, which comes
in contact with the flushing lever, which is operated thereby. The basin has a few
perforations above the trap to prevent syphoning and secure the water level. Just
above the flushing trap 1 fit a cleansing cover, for cleaning the trap when required.
The connection with the soil trap is made circular, and is so formed that the drain
pipe may be placed at any angle relatively to the position of the pan.
In applying my improvements to valveless closet pans, I form the basin cellular,
and divide the flow of the flushing water, part thereof passing down the inside
surface and the remainder down the annular space round the pan, and through holes
formed in certain parts of the pan.
In applying my invention to a syphon valveless closet, I form the syphon at the
back of the pan, and form a trap at the lower end of the syphon. The flushing
water enters the pan through the usual lip, and a trapped entrance for the water is
also formed at the upper end of the syphon. The quantity of water remaining in
the pau after flushing is regulated by the height of the syphon.
I also improve the method of fixing closet pans and slop sinks with lugs and bolts
or clips, whereby the flanges of the pans and traps are secured together; the slop
sinks being (preferably) fitted with semicircular strainers, to prevent the entrance
into the trap of solid matters.
In connection with the improved closets and sinks, I fit a water-waste preventer,
consisting of a glass mounted cylinder, fitted with a packed piston attached to a
rod and handle. The main supply pipe is fitted with a diaphragm formed of
rubber or other material, carrying a rubber or other valve capable of falling upon
a circular seat. By-ways for water are provided to admit water above the
diaphragm and to the piston. When the rod and piston are lifted a partial
vacuum is caused above the diaphragm, which opens the valve and allows the
water to pass. When the piston descends by its weight, a rubber or other washer

page_text: closes some of the by-ways, and thereby allows the diaphragm to descend and
close the valve, after a definite time, regulated by a set tap attached to the
by-ways..
I form a cylindrical valve for valve closet pans, consisting of a cylindrical valve-
case, having suitable openings for the passage of the soil and for ventilation. A
segmental valve is kept to its seat by a coiled or other spring or springs acting
upon its stem or otherwise. The back of the valve is fitted with a triangular
copper case, which acts as a guide and keeps the spring clean. The valve is actuated
by a segmental pinion driven by a segmental rack, attached to and operated by the
usual lever and handle.
Connections with ventilating pipes are fitted to all the above described closets.
Improvements in the Construction of Water-closets, and in Flushing,
Trapping, and Supplying the same with Water.
I, JAMES GEORGE STIDDER, of 66 Waddon Old Road, Croydon, in the County
of Surrey, Sanitary 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 effect improvements in the construction of
water-closets, and in fitting the same with valves and other appliances, for the
purpose of rendering the action of the valves noiseless; preventing the return of
noxious gases; securing an abundant flush, and preventing the waste of water.
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
figures of reference indicate corresponding parts.
In applying my improvements to valve closet paus, as shown in perspective in
Fig. 1, and in sectional elevation in Fig. 2: I form the rim 10 in such a manner
that a complete "all round "flush is secured, openings 11 being formed at the side
of one portion of the rim, leading to a trap 12, the overflow edge of the trap being
at such a height as to regulate the height of water remaining in the pan, after the
flushing of the pan has been effected.
"
I fit the stuffing box to the sunk cup 13 with "woodite' or other packing,
through which the rod passes to the lever, to render it air-tight, and to keep
the rod in a vertical position. The fulcrum 14 of the lever 15 is adjustably
pivoted to a spring 16, which allows the fulcrum to adjust itself to the motions
of the lever. The lever 15 is adjustably connected to the spring 16, by a sliding
block 19, secured to the spring by a screw pin passing through a slot in the
spring, and secured in position by a nut; the adjustment being made by the screw
clamp 62; after which the nut is turned, fixing the sliding block 19 in position.
A stud 17 on the lever works in a slotted lever or cam 18 attached to the valve
cover, the slot being so formed that, when the valve is closed, the stud locks the
valve in that position. A lug 20, attached to the lever rod 21, is fitted with a
rubber or other suitable roller 22 in a fork 23, which rubber roller comes in contact
with the flushing lever 24, which is operated thereby. The basin has a few
perforations at 11 above the trap, to prevent syphoning and secure the water level.
Just above the trap 12 I fit a cleansing cover 25, for convenience in cleaning
the trap, when required. The conuection with the soil trap 26 is made circular
at 27, and is so formed that the drain pipe 28 may be placed at any angle,
relatively to the position of the pan.

page_text: The motion of the lever 15 is regulated by a buffer stop 63 secured to the
framing of the closet, preferably as shown in Fig. 1, the stop being fitted with a
rubber or other suitable buffer to prevent noise.
In applying my improvements to valveless closet pans, as shown in sectional
elevation in Fig. 3 and in sectional plan view on the line a b in Fig. 4: I form
the rim 29 cellular, and divide the flow of the flushing water, part thereof passing
round the annular space 30, and through holes 31; and the remainder through the
annular space 32 round the pan, and through holes formed therein leading into
-the pan.
In applying my invention to a syphon valveless closet, as shown in sectional
elevation in Fig. 5, and in horizontal sectional plan view on the line ed in Fig. 6: I
form the syphon 33 at the back of the pan, and form a trap 34 at the lower end of
the syphon.
The Anshing water enters the pan through the usual lip 31. A trapped entrance
for the water is formed at 35, as shown in Fig. 5. By these means I am enabled
to obtain a syphoning action without the use of the separate pipe, which is usually
employed for the purpose. The water passing down the supply pipe is divided:
one portion entering the basin, and the other passing through the trap 35 to the
top of the syphon 33 by the pipe 64, thus starting the syphoning. The syphon
is also fitted with a relief valve 65 for the escape of air when the basin is being
filled, and also for passing away any extra pressure of foul air which may accumu-
late in the syphon 33 by the arrangement shown in Fig. 7. The quantity of water
remaining in the pan, after flushing, is regulated by the height of the lip of the
syphon at 36.
In connection with the improved closets and sinks, I fit a water-waste preventer,
as shown in sectional elevation in Fig. 8. I mount a glass cylinder 37 in a metallic
cylinder 38, and fit it with a packed piston 39 and piston rod 40 passing through a
stuffing box 41. A lever joint 42 is fitted to the rod. The main supply pipe 43 is
fitted with a diaphragm 44, formed of rubber or other material, carrying a rubber
or other valve 45, capable of falling upon the circular seat 46. By-ways 47, 48
and 49, for water are provided to admit and pass away water to and from the
piston and above the diaphragm. When the rod 40 and piston 39 are lifted, a
partial vacuum is caused above the diaphragm; this operation opens the valve 45
and allows the water to pass, as shown by the arrows. When the piston descends
by its weight, a rubber or other washer 50 closes the by-ways 48 and 49. The
water entering by the passage 47 above the diaphragmn causes it to descend and
close the valve, after a definite time, regulated by the set-tap 51, controlling the
by-way 47.
I form a cylindrical valve for valve closet pans, as shown in sectional elevation
in Fig. 9, consisting of a cylindrical case 52, having openings at 53, 54 and 55.
The opening 53, leads to the closet pan, 54 to the drain or trap, and 55 to the
overflow pipe. 56 is a segmental valve which is kept to its seat by the coiled
spring 57 surrounding a guide pin 58. The back of the valve is fitted with a
triangular copper case 59, which acts as a guide to the valve and keeps the spring
clean. The spindle extends to the outside of the valve box, passing through a
stuffing box, and is actuated externally by a segmental pinion 60, driven by a
segmental rack 61, attached to and operated by the usual lever and handle.
openings in the valve box and the method of actuating the same may be otherwise
arranged.
The
Connections with ventilating pipes are fitted to all the above described
closets.
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 :
1. The improvements in the construction of water closets, and in flushing,

page_text: trapping and supplying the same with water, substantially as and for the purposes
