PROVISIONAL SPECIFICATION.
An Improved Flushing Apparatus for Closets and the like.
I, WILLIAM HENRY BLY, of Vauxhall, Great Yarmouth, in the County of
Norfolk, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This my invention has reference to an improved flushing apparatus for flushing
closets and the like, and the object of the invention is to provide a more powerful
flush than has hitherto been possible by those apparatus in use. By this invention,
moreover, long vertical flush-pipes are dispensed with.
2.
An apparatus made in accordance with this invention consists of a strong cistern
or receptacle of sufficient capacity to contain the quantity of water required for,
flushing a closet or the like at one time, and also to contain a sufficient quantity of .
compressed air to produce pressure.
The cistern or tank aforesaid is situated in any convenient place, and is provided
with an inlet and outlet. Both the inlet and outlet are provided with a double
way cock, or with valves which are arranged in such manner that no water can be
ejected from the cistern until the supply has been cut off. The double way cock
or valves are operated by a float contained within the cistern, and which closes the
supply valve when the required quantity of water has been admitted to the cistern.
By this arrangement, when the water enters the cistern, the air (which may enter
through any suitable valve when the cistern is empty) is compressed, and causes
the water to be ejected with great force.
I do not wish to confine myself to any particular form of cock or valve for
admitting and ejecting the water, nor to the number of cisterns required to carry
out my system, for it is evident that many kinds of cocks and valves might be
employed, and, further, that in some cases more than one cistern may be
required.

COMPLETE SPECIFICATION.
An Improved Flushing Apparatus for Closets and the like.
I, WILLIAM HENRY BLY, of Vauxhall, Great Yarmouth, in the County of.
Norfolk, Gentleman, 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 my invention has reference to an improved flushing apparatus for closets
and the like, and the object of the invention is to provide a more powerful flush
than has hitherto been provided by apparatus at present used.
By this invention, long vertical flush pipes of large area can be dispensed
with.
I now proceed to describe my said invention, reference being had to the
accompanying drawings, and to the figures of reference marked thereon, like figures
referring to like parts throughout all the views.
Fig. I is a vertical sectional elevation of my improved flushing apparatus.
Fig. 2 is a detail view.
Fig. 3 is a vertical sectional elevation shewing the apparatus with two cisterns.
My invention comprises a strong cistern or chamber 1, of sufficient capacity to

page_text: contain the quantity of water required to flush, (preferably from two to three
gallons) in addition to the area for compressed air." The cistern is closed at both
ends as shewn. A guide and stay rod 2 passes centrally and vertically through the
cistern. A float 3, preferably consisting of a hollow cylinder baving a central
aperture 4 is adapted to slide vertically upon the rod 2. A connecting rod 5,
baving its upper end pivoted to a lug 6, on the underside of the float 3, has its
lower end pivotally connected to a lever 7, pivoted to a lug 8 forming part of, or
secured to the cistern cover 9. The lever 7 has a pin or projection 10 on its side
which engages and supports the free end of a lever 11, pivoted at 12 to a lug 13.
A valve-seat 14 is fitted in the cylinder cover 9, and contains a T-valve 15 opening
inwards into the cistern 1. A double-way-plug cock 16 is secured to or cast
integral with the cover 9, and consists of a casting 17, having two bores 18 and 19;
the former for the inlet, and the latter for the outlet of water to the cistern. A
plug 20 having diametrical ports 21 and 22, corresponding with the bores 18 and 19,
is fitted in the casting as shown. The plug is kept in position, and the wear of the
plug can be taken up by a screw 23 passing through the cap 24 screwed to the
casting 17. The plug 20 has a lug 25 to which is pivotally attached the rod 26
whose opposite end passes through and rests in the lugs 27 of a bracket 28. A
lever 29 is mounted upon the rod 26 between the lugs 27, and is keyed or otherwise
secured thereto. Any suitable handle 30 is secured to the upper end of the
lever 29.
In Fig. 3 I have shewn my improved apparatus fitted with two tanks, which are
connected by the pipe 32, but only one of which is fitted with a float, levers, and
inlet-valve. In this form, the double-way cock is fitted to the pipe 32, and the
lever 29 may be attached to the lug 25, as shewn. It will be readily understood
that several cisterns can in this way be connected up where a very large flush is
required.
The manner in which my improved apparatus is operated is as follows:
When the plug 20 and the hand-lever 29 is in the position shewn in Figs. 1
and 3, the outlet 19 is cut off, whilst the inlet 18 is open. The pressure of the
water in the inlet tube 18 raises the valve 15, and the water rises in the cistern,
raising the float; the water compressing the air in the upper part of the cistern.
As the float rises it lifts the rod 5 and the lever 7, which in turn raises one end of
the lever 11 resting upon the pin 10, whilst the shorter end 33 of the lever 11
depresses and gradually closes the valve 15. Now when the lever 29 is drawn
down (as shewn by dotted lines in Fig. 2) the rod 26 and plug 20 is turned, thus
shutting off the supply through the bore 18 and opening the outlet 19. The
pressure of air in the upper part of the cistern will now rapidly expel the water, as
will be understood.
The manner in which the alternative form shewn in Fig. 3 operates is the same
as in that form shewn in Figs. 1 and 2.
Although I have shewn and described a double way cock operated by a hand-
lever, it will be readily understood that other valves may be employed to control
the inlet and outlet without departing from the principle of this invention.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I.
claim is :-
1. An improved flushing apparatus for closets and the like, consisting of a closed
cistern containing a float adapted to be raised by the water, and arranged to control
the inlet of water to the said cistern, substantially in the manner and for the
purposes herein before set forth.
2. A flushing apparatus comprising a closed cistern containing a float, connected
to a system of levers, combined as described and shewn, to automatically regulate
the inlet of water to the cistern, and a double-way cock adapted to open the inlet
and close the outlet, or open the outlet and close the inlet simultaneously, substaṇ-
tially as and for the purposes hereinbefore set forth.

page_text: 3. An apparatus for flushing closets and the like, comprising one or more cisterns,
one or more of which contains a float adapted to be raised and lowered upon a
guide-rod by the water, a lug upon the underside of said float, a connecting-rod
pivoted to said lug, a lever having one end pivoted to the lower end of said
connecting-rod, and its other end pivotally connected to a lug within the cistern, a
projection upon said lever, a lever pivoted to a lug in the cistern and having one
end resting upon the projection aforesaid, and its other end upon an inlet valve-
arranged in the cylinder, in combination with a double-way cock or other valve
mechanism for controlling the inlet and outlet of water, all substantially as and for
the purposes hereinbefore set forth.
