PROVISIONAL SPECIFICATION.
Improvements in Water Waste Preventers for Flushing Purposes.
SAMUEL THOMPSON and JAMES MEWEN trading as Samuel Thompson & Co.,
Ironfounders at Millfield, Works, near Wolverhampton Staffordshire do hereby
declare the nature of the invention to
Improvements in water waste preventers for flushing purposes, consisting of a
hollow metal cylindrical vessel or well, standing upon pegs or feet, and having a
smaller hollow cylinder inside as shown in the annexed drawing Fig. 3; the space
between the inner & outer cylinder, forms the well, the whole being part of a syphon
the down pipe of which passes through the said inner cylinder, and when covered
with a hollow bell or plunger, the flang of which fills the space or nearly between
the inner & outer cylinder, making the syphon complete. The action of this
syphon is that when the bell or plunger is raised, by pulling the lever to which it is
attached, no water escapes from the cistern, but immediately the lever is released
from the hand, the descent of the bell or plunger within the well, forces the water
into the down pipe fixed through its centre, in sufficient volume to fill the said pipe
& so causes the whole to act as a syphon until the cistern is emptied.
Our claim is in respect of the cylindrical vessel or well only, & its application as
part of a syphon.
Fig. 1 is a plan of the said well.
Fig. 2 is a section of the same.
Fig. 3 is an elevation of the same.
The said well is senarate & distinct from the cistern but may be fixed therein.

Improvements in Water Waste Preventers for Flushing Purposes.
SAMUEL THOMPSON and JAMES MCEWEN Ironfounders, Millfields Works,
near Wolverhampton in the County of Stafford 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 that class of siphon flushing cistern in which a bell or
plunger and a down-pipe is arranged; in combination with these we introduce the
novelty of a loose well, standing within the cistern upon pegs or feet, consisting of
a hollow, metal, cylindrical vessel, separate from the cistern, having a smaller
hollow cylinder inside, as shewn in Figure 3; the space between the inner and
outer cylinder forms the well being part of a siphon; a down pipe passes through
the said inner cylinder and when covered with a hollow bell or plunger, the
bottom of which fills the space, or nearly so, between the inner and outer cylinder,
the siphon is complete. The action of this siphon is that when the bell or plunger A
is raised by pulling the lever B to which it is attached no water escapes from the
cistern Fig. 4, but immediately the lever is released from the hand the descent of
the bell or plunger within the well, forces the water up the annular space between
the down pipe and the inner cylinder of the well and of the bell, over and into the
down-pipe C in sufficient volume to fill it and thereby sets up a siphon action
which continues until the cistern is emptied; a second di-charge cannot be obtained
until the cistern is re-filled and the handle again pulled and released.

Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
The combination with a flushing tank ei term, of a loose metal well.
