Year: 1870

page_text: LETTERS PATENT to Isaac Haigh, John Haigh, and Isaac Haigh,
junior, of Westbromwich, in the County of Stafford, Plumbers, for
the Invention of " CERTAIN IMPROVEMENTS IN APPARATUS IN CONNECTION
WITH WATERCLOSETS."
PROVISIONAL SPECIFICATION left by the said Isaac Haigh, John
Haigh, and Isaac Haigh, junior, at the Office of the Commissioners
of Patents, with their Petition, on the 16th September 1870.
We, ISAAC HAIGH, JOHN HAIGH, and .ISAAC HAIGH, junior, of West-
bromwich, in the County of Stafford, Plumbers, do hereby declare the
nature of my said Invention for “CERTAIN IMPROVEMENTS IN APPARATUS IN
CONNECTION WITH WATERCLOSETS," to be as follows (that is to say) :-
:-
Our Invention appertains solely to the means of flushing waterclosets,
and consists in the application to the ordinary syphon, as applied to a
small reservoir or flush box, of an additional vent way, fitted with a valve
and seat, the said valve being connected by a chain and link to a balance

page_text: lever, the link encompassing the lever of the ball connected with the tap
for controlling the supply, by which means the flushing is brought more
immediately under the control of the user of the closet by a rod or other
connection with the balance lever before referred to.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Isaac Haigh, John Haigh, and Isaac Haigh, junior,
in the Great Seal Patent Office on the 16th March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ISAAC
HAIGH, JOHN HAIGH, and ISAAC HAIGH, junior, of Westbromwich, in
the County of Stafford, Plumbers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth-day-of-September,-in-the-year-
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Isaac Haigh, John Haigh, and Isaac Haigh,
junior, Her special license that we, the said Isaac Haigh, John Haigh,
and Isaac Haigh, junior, our exccutors, administrators, and assigns, or
such others as we, the said Isaac Haigh, John Haigh, and Isaac
Haigh, junior, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "CERTAIN IMPROVEMENTS IN APPARATUS IN CONNECTION WITH WATERCLOSETS,"
upon the condition (amongst others) that we, the said Isaac Haigh,
John Haigh, and Isaac Haigh, junior, by an instrument in writing under
our hands and, seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
KNOW NOW YE, that we, the said Isaac Haigh, John Haigh, and
Isaac Haigh, junior, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly

page_text: described and ascertained in and by the following statement (that is
to say):
Our Invention appertains solely to improved means for flushing water-
closets, and consists in the application to the ordinary syphon (as
applied to a small reservoir or flush box) of an additional controllable
vent way fitted with a valve and seat, the said valve being connected by
a chain and link or other suitable means to a balance lever; the link
may encompass the lever of the ball connected with the tap for con-
trolling the supply, or be otherwise arranged. By these means the
flushing of closet pans is brought more immediately under control by
connecting a rod or other suitable means with the balance lever before
referred to:
In giving effect to our Invention some diversification may be adopted
without affecting the general object, but the plan exhibited in the
Drawings hereunto annexed, and which we will proceed to describe,
we have found easy and simple of construction and economic and
officient
Fig. 1 is a side elevation with the side of the flush box or reservoir A
removed for the better exhibiting the action and details; B is the
syphon, which has a break or additional pipe at B' for the purpose of
receiving a vertical valve and seat hereafter referred to, from whence
the syphon descends through the pipe B", its connection with the
reservoir or cistern at this part being effected for convenience with an
union joint, a mode of connection well known and understood in the
plumbing trade. Thus the pipe B" descending to the closet pan forms
the outlet from the flush box or reservoir A. The inlet is effected
through the pipe C from any convenient source, either ordinary water
supply or a head reservoir, the water being delivered through the pipe D,
which is brought under control as to closing and opening by the ball E
and lever F; from the latter a vertical lever projects marked G,, and it is
from this vertical lever that we derive or apply the working, action
which we effect by the lever H, H, working on a fulcrum at I. On the
part H of this lever a compensating weight is applied marked J, and
between the weight J and the lever Gʻan opening is formed in the
extended end of the lever H' for the lever G to pass up through the end
of such slot or opening towards the fulcrum, and forms the surface that

page_text: operates on the inner surface of the vertical lever G; as the lever H
moves in the dotted arc a, b, the lever G is forced towards the left by
means of the rod K attached to the extreme end of the lever H, and just
in proportion to the distance that this portion of the lever H is pulled
down, so the other end of the lever marked H¹ is elevated, and as this is
elevated the valve L is lifted from the seat and the syphon set in action,
and at the same time the ball F is elevated, so as to close the inlet water
way through C and D, but as the flow way of the syphon is larger than
the inlet D the flushing is rapid and exhaustive; the descent of the
ball F opens the supply tap, permitting the flush box to refill itself
progressively, correcting its overflow by the buoyancy of the ball E,
thus no matter how sudden the lever H may be operated on by the
rod K, and the valve L (which forms an important feature of our
Invention) restored to its place, the syphon being once set in motion
will exhaust the whole of the water in the flush box down to the level of
the mouth of the syphon marked M. As a matter of detail we may
observe that at the extremities of the lever H and H¹ we prefer applying
a packing, say, of india-rubber, leather, or other suitable material, as
exhibited at N, N, merely to check the concussion of the sudden pulling
down of the lever by the rod, or the dropping of the other end by the
gravitating effect of the weight J, which weight instead of being placed
as here shown may be put to the extreme end, and regulated by a weight
working on a screw, so as to advance or retire it to or from the fulcrum,
as shown in dotted lines at P; and instead of using the surface of the
end of the slot in the lever H¹ to operate on the vertical lever G, a
friction roller may be applied in the said slot for the periphery of the
roller to work against the surface of the lever.
Fig. 2 is simply a top view of Figure 1, all the parts referred to in
the one Figure being marked and defined with the same letters in the
other.
In some instances the flush box may be divided into two parts
separating the supply of water so effectually that mischievousness will
not have the effect of converting the apparatus into a continuous water-
way or wasteful flow, and yet to preserve the essential advantages of our
Invention. We effect this by admitting the water into the division or
part Q, Fig. 3, from whence it flows into the part R through a small
pipe near the bottom marked S; and to put our apparatus in motion we
simply pull down the lever T by the ordinary handle and rod, and being

page_text: .
fastened to the part U which works through the sides of the flush box
at c and e, forms the fulcrum of its action, and to this fulcrum or axis
the lever V is secured, having a weight at its end capable of regulation
or otherwise, as described at Figure 1, and with the buffer or pad N to
prevent concussion. To the lever V a chain is fixed, connected with a
valve hercafter referred to, and simultaneous with the elevation of the
lever V, the syphon is set in motion and the lever W descends, and by
means of a valve and chain cuts off the supply of water from the division
or cistern Q to the flush box R, but the syphon being set will permit the.
water to flow rapidly from the flush box R until it is below the mouth of
the syphon marked X, Fig. 4, which is a side elevation of Figure 3 with
a portion of the divisional plate Y, Y, removed for the purpose of
showing the valve Z before referred to, connected by the chain ƒ, f, to
the lever V, and in this view we are also enabled to show the lever W
also working on the fulcrum g, g, and to which lever W the valve is
attached by the chain k, k, which valve may have a stalk passing through
a transverse bar within the pipe A' to always insure its dropping correctly
on its seat, and it is through this open valve way that the water flows
into the flush box R, the regulation of the water in the part Q by means
of the ball and tap will always regulate the supply of water to the flush
box R, but the moment the arm T is pulled down the valve / will be
closed and the syphon started, and however sudden the valve Z may be
restored the outlet of the syphon being so much larger than the supply.
pipe A all waste water is prevented, for the moment the syphon has
done its work it becomes immediately inactive from air passing in at its
mouth X, and will remain so until the valve Z is again lifted.
In Figures 3 and 4 we have represented an inlet waterway differing
in its action from that represented at Figures 1 and 2 to the extent that
we prefer fitting a loose valve within the delivery pipe, and lifting the
O said valve by the lever D¹ in connection with the float ball E¹; a part
section of this arrangement we have exhibited detached at Fig. 5, in
which we have shown a part of the lever D' working on its fulcrum m,
while the curved extended part n is brought in contact as the water
flows out of the cistern Q with the stalk of the valve p, and thereby
5 elevates it, permitting the water to flow in until sufficient has entered
the vessel Q to elevate the float ball E¹, causing the valve to descend
and stop the flow of water into the cistern Q, which valve will be
rendered by this arrangement secure from all undue leakage by the
pressure of the water on the top of the valve.

page_text: Having now given a description of our Invention as practically
arranged for giving effect to our improvements we wish it understood.
that we do not limit ourselves to any proportion or detail of construction,
as either may be greatly varied without affecting the principle or object
of our Invention; as, for instance, the flush box, or flush box and
attached cistern, may be made of wood, lead, or iron fashioned or shaped
to any design or proportion adapted for particular positions; and the
levers may be formed or made of wood, cast iron, or other metal
galvanized or otherwise coated if desired; but what we claim and wish
to protect by these our in part recited Letters Patent is, the valves L
and Z or their equivalents in connection with syphons of flushing
apparatus for supplying water to closets and their attendant requirements,
such as wash basins, urinals, and other like or equivalent purposes where
certain measured supplies of water are required.
In witness whereof, we, the said Isaac Haigh, John Haigh, and
Isaac Haigh, junior, have hereunto set our hands and seals, this
Twenty-second day of December, in the year of our Lord Onc
