PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus for Water-Closets.
I, JOHN THOMAS GIBSON, Junior, of 57 Wymer Street, Heigham Road, Norwich,
in the County of Norfolk; Church Plumber; do hereby declare the nature of
this invention to be as follows:-
This invention relates to flushing apparatus for water-closets which is so con-
structed and arranged as to be practically noiseless when in operation, and
adaptable to be used either at the right or left side of the closet.
The invention comprises an outer vessel or container in which a tipping tank
is mounted on trunnions which latter pass through the sides of the container and
are squared or otherwise formed for the adjustment thereon of a correspondingly
shaped lever arm, to the free end of which the pull chain is affixed.
Through one side of the container passes the service pipe furnished with a ball
float valve situated so as to discharge into the tipping tank. To the float arm is
secured one end of a chain, cord or other flexible connection the other end of which
is affixed to the side of the container in such a position that the rising side of the
tipping tank as it turns over draws the chain, cord or other flexible connection
taut, thereby raising the ball float and shutting off the valve while the tipping
tank is being emptied.
An air pipe or vent leads from the discharge pipe in the bottom of the container
and opens above the top of the tipping tank to allow the air, displaced from said
discharge pipe by the flush, to pass off.
By a downward pull on the chain the tank is tipped over and the flush emptied
into the container from whence it passes through the discharge pipe to the closet,
the ball valve having been meanwhile closed by the rising side of the tipping tank
drawing taut the chain or other flexible connection on the ball float arm and closing
the valve as before described.
To deaden the noise of the moving parts the chain or other flexible connection
may pass over a rubber covered or other roller fixed between guide arms on the
sides of the tipping tank, and stops to limit the two extreme positions of said
tipping tank are fixea in suitable positions on or to the interior of the container
and are made of rubber, wood or other sound-deadening material. If desired, to
prevent the empty tank from falling back too quickly after the flush has been
delivered and the handle released, a toothed wheel may be fixed on one or on both
trunnions each gearing with a quadrant, or with another toothed wheel, fast on the
side of the container.
By making both trunnions alike the flushing apparatus is adapted to be placed
on the right or left side as required, and for the same purpose the container is so
fitted that the service pipe may be coupled up to either side according to
requirements.

I, JOHN THOMAS GIBSON, Junior, of 57 Wymer Street, Heigham Road, Norwich,
in the County of Norfolk; Church Plumber; 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:-
This invention relates to flushing apparatus for water-closets which is so con-
structed and arranged as to be practically noiseless when in operation, and
adaptable to be used either at the right or left side of the closet, and in which the
supply is shut off while the flush is being delivered.
In the accompanying drawings Figs. 1 to 3 show one form in which my invention
may be carried into practice, and Fig. 4 is a modification thereof. Fig. 1 is a
longitudinal section taken on the irregular line of Fig. 2; Fig. 2 is a transverse
section taken on the line y y of Fig. 1; and Fig. 3 is a partly sectional plan of
Fig. 2. Fig. 4 is an end clevation showing a modification of my invention. The
same letters of reference where they occur are used to denote the same or
corresponding parts in all the Figures.
In the form shown in Figs. 1 to 3, my flushing apparatus comprises an outer
tank or container A in which a tipping tank B is mounted on trunnions 6 which
latter pass through the sides of the container A and are squared at their outer ends
or otherwise formed for the adjustment thereon of a correspondingly shaped lever
arm C, to the free end of which the pull chain D is affixed. Or the trunnions may
be cylindrical at their ends as showir and the lever arm C fitted thereon by means
of a cottar pin or the like.
The tipping tank B is placed in position in the outer tank or container. A by
passing the trunnions b into long slots a in the sides of the container A which
said slots extend from the upper edge for a suitable distance downward and in the
bottom of each is a half bearing block a' into which the trunnions are received.
When the trunnions b are in position in the lower blocks a', the top half bearing
blocks as are passed down the slots, and on top of these blocks a³, filling pieces a
are placed, or the blocks a may be made in one with the filling pieces a³. The
blocks a' and as, and the filling pieces a are wider than the slots a and are furnished
with central longitudinal grooves in their sides by which they are fitted to the
sides of the slots and form tongue and groove joints (see Figs. 1 and 3); the parts
are secured by bolts passed through ears at formed on the upper ends of the filling
pieces a³, (see Figs. 2 and 3).
The
Through one side of the container A passes the service pipe E furnished with
a ball float valve F situated so as to discharge into the tipping tank B. To the
float arm G is secured one end of a chain, cord or other flexible connection H the
other end of which is affixed to one arm J' of a lever pivotted at J to a post. Js on
the side of the container A and having a counterweight. Je on its other arm.
post J is situated above the upper front edge of the tipping tank and is of sufficient
length to hold the counterweighted lever over the tipping tank B, as shown in
Figs. 2 and 3. On the counterweight J, or on the same arm of the lever, is a. stop
arm which projects forward and rests on the upper front edge b' of the tipping
tank B in the manner shown in Fig. 2, thereby holding up the counterweight Ja
so that the chain, cord or other flexible connection H is sufficiently slack to.allow
the ball G' to fall to the lowest position in the tipping tank B.
By a downward pull on the chain D the tank B is tipped over into the position
shown by the dotted lines in Fig. 2 and the flush emptied into the container A, from
whence it passes through the discharge pipe K to the closet. By the tipping of

page_text: the tank B the front edge b' has been removed from under the stop arm j, and the
support being removed therefrom, the counterweight Ja comes into operation and
falls to the position shown in dotted lines in Fig. 1 thereby holding up the chain,
cord or other flexible connection H and with it the ball float G' in the position also
shown in dotted lines in Fig. 1, thus shutting off the valve F, and stopping the
supply of water during the period that the tank B is being tipped. This result is
effected whether the tank B is full when the chain is pulled or is in the act of
filling. In the former case the ball float G' is already in its highest position with
the supply shut off and is prevented from falling so as to open the valve until after
the tank has returned to its normal position. In the latter case the tipping of the
tank raises the ball float thus shutting off the supply until after the tank has
returned. On releasing the pull on the chain D, the tank B returns to the normal
position and in coming back the front edge b' takes under the stop arm j and
raises the counterweighted lever to the normal position the parts being then as
shown in the full lines in Fig. 2.
An air pipe or vent L (see Fig. 2 leads from the discharge pipe K in the bottom
of the container A and opens above the top of the tipping tank B to allow the air,
displaced from said discharge pipe K by the flush, to pass off. L' is a shelf or
ledge secured on the inside of the container A to stop the water splashed upwards
by the flush.
To deaden the noise of the moving parts the stop arm and the post J³ are
covered with or made of rubber, leather, wood or other sound-deadening material.
M is an overflow pipe fixed on the back of the tipping tank B and discharging
into an overflow trough N.
If desired, to prevent the empty tank from falling back too quickly after the
flush has been delivered and the chain D released, a toothed wheel may be fixed on
one or on both trunnions 6 each gearing with a quadrant, or with another toothed
wheel, fast on the outside of the container. Or as shown in Fig. 4 the lever arm C
may turn on a pin C' on the outside of the container and may carry a toothed
sector C which gears with a toothed wheel C3 fast on the trunnions b.
By making both trunnions alike, the lever arm C may be fitted to either and
the flushing apparatus thus adapted to be placed on the right or left side as
required, and for the same purpose the container may be made with a service inlet
aperture E' on each side thereof as shown in Fig. 3 so that the service pipe E may
be fitted into either side according to requirements.
In the modification shown in Fig. 4 the float arm G is secured to one end of a
chain, cord or other flexible connection H, the other end of which is affixed to the
side of the container in such a position that the rising side 6 of the tipping tank B
as it turns over draws the connection H taut, thereby raising the ball float and
shutting off the valve as before described. To deaden the noise, the connection H
passes over a rubber covered or other roller 63 rotating in suitable bearings carried
on the upper edge of the rising side 6 of the tipping tank.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. Flushing apparatus for water closets comprising an outer tank or container
with a service inlet aperture on each side, a tipping tank mounted therein on
trunnions which project through the sides of said container, a lever arm adapted
to be fitted to either trunnion, a flexible connection one end of which is attached
to the ball float and the other end to a counterweighted lever supported by the
front edge of the tipping tank and pivotted to the front of the container the
moving parts being provided with sound-deadening stops, all arranged to operate
substantially in the manner and for the nurpose hereinbefore described and
illustrated in Figs. 1 to 3 of the accompanying drawings.
2. In flushing apparatus of the kind indicated, the means herein described with
reference to Figs. 1, 2 and 3 of the accompanying drawings for shutting off the

page_text: water supply to the apparatus during the emptying of the tipping tank, consisting
of a counterweighted lever pivotted on or to the side of the container and supported
on the front edge of the tipping tank, the said lever being attached by a flexible
connection to the ball float substantially as described.
3. The modified means for shutting off the supply to the apparatus described
with reference to Fig. 4 wherein the ball float is connected to the rear of the
container by a flexible connection which passes over a roller carried on the upper
edge of the rising side of the tipping tank substantially as and for the purpose
herein before set forth.
4. Flushing apparatus for water closets arranged to operate substantially in the
