A New or Improved Flushing Device and Water Waste Preventer.
I, SHANKER ABAJI BIIISE, of No. 84, Clapham Road, London, S.W., Professor
of Arts, do hereby declare the nature of this invention to be as follows:
-
This invention relates to a new or improved flushing device and water waste
preventer especially applicable for flushing or flushing and disinfecting, water
closets and the like; as well as for discharging a definite quantity of water at
every operation for domestic and other purposes; and has for objects to provide
a simple and reliable device or apparatus for flushing, or flushing and disinfecting
water closets and the like (automatically if required) from the main water pipe
without the use of separate overhead syphon tanks, and to prevent water waste
when used as a water tap for domestic purposes, public water stands, and other
such like purposes.
The device or apparatus, according to this invention consists essentially of an
elbow piece, attached or connected to the main water pipe forming the nose or
nozzle of my flushing device and water waste preventer, and a vertically acting
piston or plunger controlling the passage of the water therethrough with the
operating mechanism hereinafter described. The device is enclosed in a rectan-
gular casing, provided with suitable doors, for easy access to the parts when
required, through which casing the lower end of the nose or elbow is allowed to
project. Water may be drawn from thence or a branch pipe may connect the
elbow with the closet, urinal or other place to be flushed. To permit the plunger
or piston to be raised or lowered and the passage through the elbow to be thus
opened or closed the horizontal portion of the elbow (near the bend) is provided
with two cylindrical openings, one above and opposite the other, the upper one
being surrounded and enclosed by a cylindrical cap (which may have an opening
therein closed by a screwed cap) of a sufficient height to contain the piston or
plunger when raised, and the passage way open; and the lower opening is
enclosed by a collar or cap forming a seating for the piston or plunger when said
piston or plunger is lowered and the flow of water shut off.
Below the lower cap there is a metal plate to which the piston is rigidly
connected by two vertical bars capable of sliding up and down in vertical grooves
made in the side of the upper cylindrical opening and corresponding holes made
in the bottom cap. A tin, or other box open at the top and having one end
concave so as to slide on the vertical round part of the nozzle or elbow is rigidly
attached to the metal plate. A trap is made in the bottom of the box with an
adjusting piston having a T-shaped pin dependent therefrom. A bent lever
having at its vertical end a hook nose and at its horizontal end a small hollow
tin cube is fulcrummed to one side of the concave end of the box and a similar
lever is attached to the cube and fulcrummed to the other side of the concave.
Two vertical pins having their lower ends bent at right angles are rigidly fixed
to the side of the bent pipe or elbow in such relative positions that the hook noses
of the fulcrummed levers aforesaid rest slidably upon them. In lieu of two hook
nosed levers being provided, one only may be employed if desirable. A small

page_text: outlet tube with a regulating cock and a bent end is fixed to the lower portion
of the bottom cap or piston seating and leads into the tin, or other, box aforesaid.
A glass jar or tin case or other suitable receptacle may be fixed upon the
apparatus for storing any liquid disinfectant and to a perforation made in the
bottom of said receptacle is fixed the upper end of a small tube vertically fixed
in a corner of the rectangular casing and having its lower end bent and provided
with a regulating cock to the piston of which the end of a weighted lever is
attached. This lever is in connection with the main operating lever. A bent
pipe is passed through a perforation in the side of the vertical part of the nozzle
and leads from the casing into said nozzle.
An operating lever pivotted to the side of the casing is used to raise the piston
from its seating when it is desired to draw water or cause a flush, and this
operating lever may be connected with the closet plate of the door for automatic
working if desired. The disinfectant fluid cock or tap before mentioned may be
also in connection with the main operating lever and be operated thereby,
allowing the disinfectant to pass from the reservoir through the pipe into the
casing and thence through the outlet pipe into the nozzle and on to the water
closet or other place. After operating the balance weight on lever will auto-
matically close the disinfectant cock or tap. It will thus be seen that as the
cock or tap is left open for a short time only, a small quantity of disinfectant.
fluid will pass automatically with every flush and it may be regulated by
attaching the chain or other connection with the operating lever nearer or farther
from the piston of said cock or tap. An adjustable flange is used for easily con-
necting the device with the main and branch water pipes.
In operation the piston or plunger is raised by means of the operating lever
and the water passage through the elbow is open to the full extent. Whilst the
water is flowing a small quantity will pass through the pipe leading from the
bottom cap or seating for the plunger into the tin or other box carried by the
piston or plunger as aforesaid, and it will thereby float or lift the hollow cube
within the box causing the hook noses of the supporting levers to slide from the
bent pin heads or carrier brackets and the box thus losing its support will
immediately fall down by gravity and in doing so will draw the piston or plunger
with it and thus close the water outlet and stop the flush. When the box falls
as above explained the projecting T-head of the piston in the trap in the bottom
thereof coming in contact with the bottom of the casing will lift the piston up
and allow the water in the box to escape into the casing from which it will flow
into the nozzle by means of the outlet tube provided as aforesaid.
When the box is lifted up again by the operating lever the hooked noses of
the supporting levers again slide over the carrier bracket heads and the box and
piston or plunger be held in such raised position to permit a fresh flush or flow
from the main. It will be seen that as the lifting of the cube will depend upon
the definite quantity of water collected in the box the passing of such required
quantity of water can be regulated by the cock provided in the inlet pipe leading
from plunger seating collar to the box.
For regulating the cock to discharge definite quantities of water accurately an
indicating wheel with an indicating needle or finger may be fixed over the top of
the device. When used as a flushing device only a small quantity of lubricating
oil may occasionally be introduced through the screwed cap covered hole in the
cylinder to ensure the smooth working of the piston or plunger: and when so
used and connected directly to the main a syphon like bent tube may be placed
in the branch pipe connecting the nozzle with the water closet to prevent foul
gases entering the water main by means of the water collected in such syphon
tube.
The device as above described is connected directly with the main water pine.
but if necessary it may be connected with a reservoir tank which may preferably
be closed to exert additional force on the water flushed by means of the air
compressed in the reservoir tank.

page_text: It will be understood that the passage of water being entirely free, the flush
will retain full pressure of water in the main water pipe. Furthermore, as the
device will not stop until, and unless it discharges the required amount of water,
it will not require a fresh operation in case the water is not running in the main
pipe.
A New or Improved Flushing Device and Water Waste Preventer.
I, SHANKER ABAJI BISE, formerly of No. 84, Clapham Road, and now residing
at No. 5, Upper Bedford Place, London, W.C., Professor of Arts, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
My invention relates to automatic flushing devices, or devices for automatically
flushing and disinfecting water closets, as well as for discharging a definite
quantity of water at every operation, for domestic purposes. The object of the
invention is to provide a simple and reliable device for automatically flushing
and disinfecting water closets from the main water pipe or reservoir tank, without
the use of separate overhead siphon tanks, and for preventing waste of water
when the device is used as a water tap for domestic purposes, or in conjunction
with public water fountains or stands. A further object of the invention is to
provide a device of the character described which will be durable and economic,
and in which springs, float-valves, ball cocks or similar mechanisms liable to
frequent disarrangement, will not be employed.
The invention consists in the novel construction and combination of a plug
located in the flushing pipe and operated by a float controlled cut off mechanism
with several other parts as will be hereinafter fully set forth and pointed out in
the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures.

Figs. 10 and 11, are transverse sections through the upper portion of the
apparatus, illustrating the application of further details of construction, Fig. 12
is a detail view of the operating levers, while Fig. 12 is a transverse section on
line XX of Fig. 12.
The flushing pipe A is of angular or elbow formation, and in its upper or

page_text: horizontal member 10, between the inlet portion of said member and the bend
in the main member, a vertical tapering chamber 11 is formed, the bottom 12
whereof is closed, the top being open, and the said chamber 11, is provided with
openings 13 and 14, connecting respectively with the main and with the hori-
zontal members of the pipe A, as shown in Fig. 1.
A dome 15 is erected upon the horizontal member 10 of the flushing pipe A
immediately over the chamber 11 therein, and said dome is of even diameter
throughout its length with the exception of the lower portion of the dome, where
from a point 15 the said interior of the dome is made to taper correspondingly
to the chamber 11: in fact, this portion of the dome actually constitutes a portion
of said chamber. An opening is made in the top of the dome closed by a cap 22
for inserting any lubricating compound in the dome if so desired.
The upper end of a pipe 15, having at its lower end a cock 15 with an
operating lever 15d, is attached to the dome 15 as shown in Fig. 11 for discharging
the water collected in the dome 15 when the plug 21 is lowered and thereby
making room for the plug when it is desired to be raised.
It will be observed that when the chamber 11 is empty or open, the water from
the main supply pipe will rush unobstructed into the inlet end of the flushing
pipe, through said chamber and out at the lower end of said flushing pipe. It is
therefore necessary that some device be provided to stop the flow of water through
said flushing pipe at stated intervals as desired. To that end a plug 21 is utilized
which operates the flush either by sliding in a vertical line or by turning on a
hinge or round its axis as hereinafter described. Referring to Fig. 1. The
plug 21 is made tapering so that it may fit snugly in the chamber 11, and its
lower end may rest upon the bottom 12 of said chamber, at which time the upper
portion of said plug will fit snugly to the inner wall of the lower portion of the
dome 15, as shown in dotted lines. The plug 21 is made of metal, or may prefer-
ably be made entirely or partly of vulcanized rubber, or like material to fit the
chamber 11 closely and smoothly.
A downwardly extending bar 23 is secured to the bottom portion of said plug
at opposite sides, as shown in Fig. 4, and these arms or rods 23 are held to slide
in vertical grooves 24 made in the inner wall of the chamber 11 and in extensions
from the outer side surfaces of said chamber, as shown particularly in Fig. 3
although when the character of the walls of the said chamber permits the projec-
tions spoken of may be omitted. The lower ends of the bars or arms 23 are
attached to a cross bar or plate 25, located below the bottom 12 of the chamber 11,
which bottom is provided with suitable apertures through which the rods or
arms 23 may pass.
In the modification shown in Fig. 10 the plug 21 is made cylindrical and
consists of a casing 11 located on the top of the nozzle or flushing pipe A, and
the cylindrical chamber 11 (in which slides the said plug) is provided with a
gland 11 at its upper end. The said chamber 11 is provided with opposing
openings 13 and 14 and a larger opening 14 in its bottom, which is in direct
communication with the flushing pipe or nozzle A. One end of a pipe 10°
encircling the outer side of the chamber 11, is connected with an opening 10d
made in the main or supply pipe 10, and the other end of this pipe is connected
with the opening 13 above described. It will be seen that the water from the
pipe 10 is let into the chamber 11 through the openings 13 and 14 which being
opposite each other cause equal pressure on the plug 21 when the latter is in
lowered position to facilitate its moving. The water from the chamber 11 passes
to the nozzle or flushing pipe A through the opening 14. A washer 10 having
a groove in its upper face, is inserted in the gland 12b at the bottom of the
chamber 11 and a similar washer 10b having a groove in its upper face is placed
and held in position in the upper gland 11. The dome 15 in Fig. 1 is dis-
pensed with, and the plug when raised passes through the washer 10b and is
operated by the rod 23 connected with the cut-off mechanism C.
It will be observed that when the plug is lowered the tapering edges 65 and 66

page_text: made respectively in the upper and lower portions of the plug, will enter the
grooves and of the washers 10 and 10° and thus effectually close the flush
and prevent leakage.
Un
Referring to the Figs. 7 and 9 I have shown the plug 21 as turning on a
hinge and round its axis respectively instead of sliding in a vertical line as
before described. Below the mouth of the chamber 11 at the end of the flushing
pipe 10, a trap door, or shutter 21 is mounted to turn on a hinge fixed to a
vertical bar A, the latter being secured to the lower part of the pipe 10.
the upper side of the shutter 21° is fixed a short plug 21, preferably made of
rubber and tapering in size to fit in the corresponding inclining or sloping
lower end of the bottom of the chamber. One end of a horizontal lever A is
hinged to the lower extremity of a vertical bar A, and its other end is con-
nected with the projecting extremity of an upper horizontal lever 23, by means
of a rod or chain 23. A vertical pin is fixed in the lever A in such a rela-
tive position that when the latter is raised up by the lever 23, the pin presses
against the lower part of the shutter 21° to cause the plug 21 to tightly close
the bottom of the chamber and thereby stop the flush. The plug 21 with the
shutter 21, instead of turning on a hinge may be made to rise and fall in a
vertical line to shut or to open the bottom of the chamber by means of two
vertical guide rods attached to the opposite sides of the shutter 21", and made
to slide in corresponding vertical slots made in the outside of the chamber.
The upper ends of these rods may be projected and connected with the lever 23.
The upper lever 23 is fulcrummed at 236 above the flushing pipe A, and its
other end is slotted or divided into two branches, similar to a fork and con-
nected with the upper extremity of the vertical rods 23 The lower ends of
these rods 23 are fixed to the opposite sides of the box 27 of the cut-off mechan-
isni C, and slide through guide plates 24 attached to the lower portion of the
main pipe 10 at opposite sides. A tube, or a cylindrical metal pipe as A¹, of
sufficient length to touch the plug when it is raised may be located in the
chamber to check the flush of water acting forcibly on the face of the plug 21
when ne latter is shut; or it may be fixed on the top of the plug, preferably
where the latter is made to rise and fall in a vertical line as before described.
Below the bottom of the chamber an outlet pipe A is fixed, and it has its upper
end sufficiently widened to freely admit the play of the shutter 21 and the
lever A
In Fig. 9, the plug 21 is shown as located in the chamber 11 in the flushing
pipe. In this modification, the plug turns a quarter revolution in the chamber 11
instead of moving up and down in a central line, as shown in Fig. 1, for allow-
ing a flush or closing the same. The plug is operated by a segment 60 of a
bevelled wheel connected with a lever 61, which latter is connected with the
rod 23, and is fulcrummed on the outer side of the chamber 11 near its bottom at
62, the attachment being made to the chamber at one side only. The upper
end of the plug 21 is projected beyond the top of the chamber 11 and at that
point is provided with bevelled teeth 63 which mesh with the teeth of the
segment 60. The lower end of the plug is reduced, and is passed through the
bottom 12 of the chamber 11 and suitably tightened by means of a nut. The
lower portion of the bottom 12 is covered by a screw cap 64, enclosing the lower
end of the plug.
The plug 21 constitutes a portion of the cut-off mechanism.
This mechanism consists of a box 27 attached to the cross bar 25, and is adapted
to slide freely in the jacket or casing B and one end 28 of said box is concaved
in order that it may fit around the vertical member of the flushing pipe A, as
shown in Figs. 3 and 4. The box 27 contains a float 29, and the horizontal
members of the latch levers 30 are attached to said float 29 at the same end, one
lever near each side of the float, and the pivot pins 31 of the latch levers 30 are
passed through that portion where the members connect and into the inner side
surface of the box 27 at its curved end 28, as shown in Fig. 3. The vertical

page_text: members of the latch levers 30 terminate in heads 32, which heads are adapted
to normally engage with keepers 33 and thus hold the box 27 in an upper position
and the plug 21 within the dome 15. These keepers 33 comprise an upper hori-
zontal member, a lower shorter horizontal meniber and a vertical connecting
member. The upper horizontal members of the keepers are secured to the flush-
ing pipe A, and the concaved end portion of the box 27 may pass upward between
the flushing pipe and lower members of the keepers 333 until the latch heads 32
of the latch levers 30 engage with the said lower members of said keepers, as
shown in Fig. 1. The box 27 may be made square, or cylindrical and the float 29
instead of being attached to the horizontal levers or catches 30, as shown in
Fig. 1, may be made square or round, to suit the inside of the box 27, see Figs. 7
and 8 and be free to rise and fall in the box in a vertical line. A square pin 27*,
attached to the bottom of the box 27, slides in a recess 29" made in the centre of
the float 29, and thus guides the rising and falling of the float. A vertical rod 30ª,
terminating with an inclined nose, is fixed on the top of the float 29. A bolt 321
slides in guides 32ª fixed to the sides of the box 27, see Fig. 8, and its projecting
end rests upon the bent end 33 of a keeper rod 331 fixed to the pipe 10. This
bent end 33 of the keeper rod 33 is hinged at the top, so that when the bolt 321
is raised with the box 27 it slips over the end 33ª of said keeper rod 331 and
reaches a position above it. A groove 30 is made in the side of the nose of the
rod 30, touching the bolt 321, and a pin placed in the centre of the bolt 32 slides
along the groove 30, so that by the rising or falling of the rod 30d with the float,
the bolt 3 is made to move to and fro, and thereby engage or disengage the
keeper, 33ª.
The box 27 is provided with an apertured well 34 in its bottom near one end,
and the apertures in the bottom of the well are normally closed by a disk valve 35,
provided with a downwardly projecting stem 36, and when the box 27 drops
sufficiently to bring the stem 36 in engagement with the bottom of the casing or
jacket B, the valve 35 is opened and the water contained in the box is permitted
to escape.
Water is supplied to the box through the medium of a faucet 37 connected by a
pipe 38 with the bottom portion of the plug chamber 11 or to the flushing pipe A.
In case of the modification shown in Fig. 7, a flexible connection 38 is fixed to the
outer end of the branch pipe 38 connected with the faucet 37, see Fig. 8, in such
a manner that when the shutter 21ª is opened, the connection is brought suffi-
ciently into the flow or column of water to pass a small quantity of water to the
box 27, and when the shutter is closed the connection is pushed aside.
The stem of the faucet 37 is provided with an attached dial 39 having a scale
thereon, as shown in Fig. 3 read in connection with a pointer 40 that extends
downwards from the under surface of the horizontal member of the flushing
pipe A as shown in Figs. 1, and 3.
Thus by setting the dial 39 to any desired point on the scale, the flow of water
through the faucet 37 and thereby the amount of water to be flushed may be
regulated as desired. When the plug 21 is in its upper position and the box 27
is locked by means of the latch levers 30, water will freely pass from the service
pipe down through the flushing pipe A, but a certain quantity of water will pass
out at the faucet 37 into the box 27, and when sufficient water is collected in the
box to raise the float 29, the latch head 32 or bolt 321 will be disengaged from
their keepers 33 and the box 27 will immediately drop, bringing the plug 21 in
closing position in the chamber 11, as described before and causing the valve 35
to open in the bottom of the box, whereupon the water from the box is dis-
charged and passes down into the coupling 16 through the medium of a short
pipe 51, shown best in Fig. 1. As soon as the plug 21 is seated water will be
cut off from the outlet end of the flushing pipe.
The box 27 of the cut-off mechanism is raised through the medium of a hand-
lever 41, which is preferably yoke-shaped or bifurcated and is pivoted at the
outside of the rounding portion of the casing or jacket B by suitable pins 42, as

page_text: shown in Fig. 3. The members of this lever 41 extend into the casing or jacket B,
as shown in Fig. 3, and engage with the under faces of projections 43 formed on
the sides of the box 27. The lever 41 is also provided with a thumb or hand
piece 44. Thus when the box 27 is in its lowest position, which is its normal
position, and it is desired to flush a closet, the hand lever 41 is pressed downward,
thereby carrying the cut-off mechanism to its upper position, focking the box to
the keepers 33 and permitting the free flow of water to the flushing pipe A, to he
cut off again when the float 29 of the cut-off mechanism is raised as described
before.
It will be observed from Fig. 11 that the main operating lever 41 is much
lower than the projection and the end portion of this lever 41 is made to turn
on a hinged end 41°, as is particularly shown in Fig. 12. On this end portion
rests the weighted lever 15d, so that when the main lever 41, is operated it raises
the lever 15 and thereby opens the cock 15º, and discharges part of the water
collected in the dome 15, before it (namely the main lever) touches the projec-
tions 43 and thereby raises the plug 21 for making a fresh start. It is evident
that as by the above means sufficient room is created in the dome for the plug
to occupy the same before it rises, it will be raised with the greatest ease.
raising the cut-off mechanism C when the main lever 41 drops down, its hinged
and 41 slides over the end of the lever 15 and occupies a position beneath it
as before, and as shown in Fig. 11.
After
In Figs. 7 and 8 another mechanism is provided for shifting the projections 43
sufficiently out of the way of the main operating lever 41, to enable the cut-off
mechanism to descend and thereby close the flush as soon as the float is actuated
on discharging the required quantity of water, notwithstanding the lever 41
is held in depressed condition for a length of time with a view of having a larger
flush thereby. The mechanism consists of two vertical rods 41 (one on each side
of the box 27) having furcations or slots, one at right angles to the other as
shewn particularly in Fig. 12 in their entire vertical length, and having their
lower ends bent at right angles, by which ends they are fixed to the casing B
on each side of the cut-off mechanism (. A flat piece 41b slides in that slot
in each of the rods 41 which is parallel to the side of the box 27, and is kept
in position by means of a pin placed in the centre of each flat piece, and which
slides up and down in the other slot which is at right angles to the piece 41b
and consequently also at right angles to the first mentioned slot in which the flat
piece 41b is disposed.
The projecting end of this pin moves in a groove or slit made in the main
operating lever 41, as is also shewn in Fig. 12. and thereby the piece 41b travels
up and down with the main lever 41. On the lower portion of the piece 41b
a pin 41 is fixed to enable the round end of the piece to be movable on its
pivot in an upward direction to allow it to slide over the projections 43 and be
brought under them while at the same time the abutment of such pin against
the side of the slotted rod 41* will prevent the said piece being moved downwardly
out of its horizontal position. The projections 43 are fulcrummed in their centres
by vertical pins attached to the opposite sides of the box 27; see Fig. 8. and their
ends projecting outside of the box 27 are normally over the top of the piece 41b
and their opposite ends engage with the wedge-like pieces 29b, fixed on the top of
the float 29 in such a relative position that when the float 29 is raised in the
box 27. the said wedges 29b being simultaneously raised push forward the ends
of the projecting pieces 43, thereby causing their outer extremities to shift
in the opposite direction and be brought out of the reach of the piece 41b;
and,so enable the box 27 to drop down as soon as the latch head 32 (see Fig. 1)
or bolt 32 clears away from the keeper 33, without being obstructed by the
piece 41b raised by the main lever 41. The projections 43 are caused to assume
their original position over the pieces 41b by any suitable means.
A receptacle D is suitably supported above the upper portion of the flushing
pipe A, and this receptacle is adapted to contain a disinfecting compound. A

page_text: pipe 45 is led from the bottom of this disinfecting receptacle down through the
casing or jacket B to the bottom thereof, its lower end 46 terminating in a stop
cock 47, as shown in Fig. 1. A lever arm 48 is attached to the key of the stop
cock, and this arm carries an adjustable weight 49, while a chain 50 or its
equivalent, is attached to the lever arm and to one of the members of the hand
lever 41.
Inder this construction it will be observed that when the cut-off mechanism
is raised by the manipulation of the hand lever 41, the lever arm 48 is carried
upward, as shown in dotted lines in Fig. 1, and at the moment the water is
supplied to the flushing pipe A, the stop cock 47 is opened, and the disinfecting
material escapes from the pipe 45, and through the medium of the pipe 51,
enters the pipes connected with the closet, and so freely mixes with the water
flushed. The moment that the hand lever 41 is released and drops to its normal
position, shown also in Fig. 1, the weight 49 will carry the lever arm 48
downward, thus closing the stop cock 47 and thereby allowing only a small
quantity of disinfectant to pass.
The casing or jacket B holding the cut-off mechanism C and the disinfecting
arrangements is provided with a door 26 at the front in order that access may be
readily gained to the interior thereof and is either fixed to the pipe 10 to en-
close the vertical portion of the flushing pipe A as shown in Fig. 3 or hung on
the main pipe 10 by two hooks or rings B as shown in Fig. 8 and then it is
free to move horizontally along the pipe 10 when it is desired to employ a longer
lever 23 in order to exert more pressure on the plug 21 to withstand high pres-
sure in the water mains.
A
Through the medium of a coupling 16 the outlet end of the flushing pipe A
is connected with a section of pipe 17 adapted to be carried to the closet, and
this coupling is preferably provided with a central flange and with right and
left-hand threads at opposite sides of the flange. A siphon-like bent tube may
be placed in the section of pipe 17, to prevent foul gases from the closet
entering the water main, by means of water collected in such siphon tube.
similar coupling 18 is provided for the inlet end of the horizontal member 10
of the said flushing pipe A, the coupling 18 serving to connect the flushing
pipe A, with the main water supply pipe 20 in a water service or with a pipe
from a reservoir tank through the medium of a fitting or branch 19 as shown
in Fig. 1.
In operation, supposing the device to be attached to the water main or reser-
voir tank pipe and the flushing pipe A at its lower end, and is connected with
a water closet or urinal, and the cut-off mechanism to to be in its upper position,
shown in positive lines in Fig. 1, the passage of water from the pipe 20 to the
flushing pipe A will be entirely free from any obstructions, and the water
will pass through the flushing pipe A and will enter the closet and flush it very
forcibly, since the full pressure of the water main is utilised. As soon as the
float 29 is raised and the latch head 32 or bolt 321 are disconnected from the
keepers 33, the cut-off mechanism will drop and stop the supply of water and
the water utilized to operate the float will escape from the cut-off mechanism.
Whenever the lever 41 is raised for the purpose of again flushing the closet,
the disinfecting material will pass from the receptacle provided for it into the
pipe connected with the closet.
The lever 41 can be readily connected with the closet plate or door for auto-

seen that as the lifting of the float 29 depends upon a definite quantity of water
collected in the box 27, the passing of such required quantity of water will be
regulated at the faucet 37, and by this means the quantity of water flushed will
be correspondingly and easily regulated as desired. The amount of disinfecting
material discharged may be regulated by connecting the link 50 with the lever
arm 48 closer to or farther from its centre.
The device is capable also of being used as a cock or tap for domestic pur-

page_text: poses, as for example, for drawing water in limited or definite quantities when
so required, to prevent waste of water, since at every operation the device will
discharge only a definite quantity of water and will automatically stop. When
it is intended for such use, the disinfecting mechanism may be dispensed with.
The device has several advantages over the present siphon flush tanks; and
it will be seen that the device does not require separate Hush tanks and can be
regulated for discharging any quantity of water and when once operated will
not stop until it flushes the required quantity of water. Consequently in cases
where the water is not running in the main water pipe, it will not require a
fresh operation, as in the case of siphon flush tanks and like devices. Further
more, the device being operated and closed at once, the flush will be uniform,
and the flush being subjected to the full force and pressure of water in the
main pipe or reservoir tank, will be very powerful and will not produce any
hissing sound due to vacuum or suction, it will not leak or overflow and will
require no waiting for refilling. The device requires but a very small place
in which to be set up, and does not necessitate any brackets or supports of
wood or of masonry, and it contains no springs, air chambers, vacuums, ball
cocks, valves or similar other parts liable to get out of order.
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. A flushing pipe connected with the main, or supply tank, receiving water
direct therefrom, a float operated cut-off arranged in connection with the said
flushing pipe, and operating mechanism for the said cut-off, said mechanism
being actuated to close the cut-off by water from the flushing pipe.
2. The combination, with a vertically movable gravity water receiver having
a valved outlet, of means for sustaining the said receiver in a raised position,
means for supplying water to the said receiver while in its raised position, and
means for releasing the said receiver, the valve of the receiver being opened
when the receiver falls.
3. A flushing pipe connected with a main or supply tank and receiving water
direct therefrom, a cut-off arranged in connection with said flushing pipe, an
operating mechanism for said cut-off, said mechanism being actuated to close
the cut-off by water from the flushing pipe, and means for regulating the
amount of water delivered to said operating mechanism.
4. The combination, with a vertically movable gravity water receiver having
a valved outlet, and devices having movement independent of the water receiver
and actuated by water in the receiver for releasing the same, of devices for
sustaining the receiver in a raised position, and means for supplying water to
said receiver when in a raised position, the valve of the receiver being opened
when the receiver falls.
5. The combination, with a flushing pipe and a cut-off arranged in con-
nection with the flushing pipe, of operating devices for the cut-off, said devices
including a float and a water receiver in which the float is arranged, said
receiver having its inlet communicating with and supplied from the flushing
pipe.
6. A flushing apparatus having a cut-off, means for operating the cut-off,
said means being normally dis-connected from the cut-off, a mechanism for
connecting said cut-off and operating means, by movements incident to the
flushing action.
7. A flushing apparatus having a float-controlled cut-off in which the float
is normally inactive, and means for bringing the float into action in connec-
tion with the cut-off, to terminate the flushing.
S. In a flushing apparatus, the combination, with a flushing pipe, a cut-off
including a plug adapted to be seated in the flushing pipe, and a water receiver
connected with the plug, and means for conducting water from the flushing

9. A flushing pipe arranged for connection with the service pipe, a float-
operated cut-off mechanism, a pivoted plug valve arranged to open and to close
the flushing pipe, an operative connection between the plug valve and cut-off
mechanism, devices for locking the float in the position to open the said valve,
and means for releasing the float and thereby affecting the closure of the said
valve, as described.
10. A flushing pipe arranged for connection with a service pipe, a float-con-
trolled cut-off mechanism, a plug mounted to turn in the flushing pipe, to open
and close the same, the plug being provided with teeth at one side of its upper
and outer portion, a toothed segment, the teeth of which engage with the teeth
of the plug, and a lever connection between the said segment and the cut-off
mechanism.
11. A flushing pipe arranged for connection with a service pipe, a dome con-
nected with the flushing pipe, a plug having sliding movement in the said dome
and in the flushing pipe, a float-controlled cut-off mechanism, a relief pipe
leading from the dome into the said cut-off mechanism, terminating in a lever
operated valve, and means for opening and closing the valve of the relief pipe
by the movement of the cut-off mechanism.
12. A flushing pipe, a chamber located above the flushing pipe, having glands
at top and bottom and grooved washers forming a portion of the glands, a
water-inlet pipe and a connection between the chamber and the flushing pipe,
a float-controlled cut-off, and a plug having sliding movement in the said
chamber and connected with the said cut-off, the plug being provided with
bevelled surfaces adapted to enter the grooves in the washers of the said glands,
as set forth.
13. In a flushing apparatus, the combination, with a flushing pipe, a cut-off
mechanism consisting of a valved receiver adapted to have movement to and
from the flushing pipe, and a plug connected with said receiver, adapted to be
seated in the flushing pipe when the receiver is in a lower position, of means
for supplying water to the said receiver from the flushing pipe and regulating
such supply, a float located within the said receiver, locking devices for the
receiver, controlled by the said float, means for conducting the water discharged
from the receiver to the outlet of the flushing pipe, and devices for raising the
said receiver, as described.
14. The combination with a flushing pipe and its cut-off mechanism, of a
reservoir adapted to receive a disinfecting material, a conducting pipe extend-
ing from the reservoir to a point below the said cut-off mechanism, the said
conducting pipe terminating in a regulating device provided with a lever arm,
