PROVISIONAL SPECIFICATION.
Improved Combination of Valve Mechanism with Hydraulic Rams.
I, WILLIAM JOHN WATT, of Teddesley Park, in the County of Stafford,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates, to an improved combination of valve mechanism with
hydraulic rams, and has reference more particularly to the feed or supply to
the said ram, and its object is to obviate or to lessen the amount of waste water
escape.
The arrangement is as follows:-A storage of water is made from time to time,
or continuously, in a tank or other convenient reservoir. Leading from the lower
part of this reservoir is a conduit to the ram. At the mouth of this conduit is
placed a counterweighted valve, and contiguous to this valve are arranged suitable
guides to receive or control a rising and falling flat. When the reservoir is
empty the float rests upon the valve and keeps it or tends to keep it down so as
to cut off the communication to the ram. To the valve is attached a cord, chain
or rod, capable of an upward and downward movement, and at a suitable point
thereon is placed a lifting piece or arm, so that when the float reaches a certain
point it lifts the valve. I, find that when the valve has thus been lifted but a little,
the counterweight commences to act, and together with the rush of water through,
the said valve opens with a rush. This sudden rush of water effectively puts the
ram into immediate action. Having used all the water in the reservoir, the float
has by this time fallen so as to again secure the closing of the valve, while the
recharging takes place.
This arrangement applies where the reservoir supply is not sufficiently speedy or
ample to keep the ram'in constant motion.

COMPLETE SPECIFICATION.
Improved Combination of Valve Mechanism with Hydraulic Rams.
1, WILLIAM JOHN WATT, of Teddesley Park, in the County of Stafford,
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 an improved combination of valve mechanism with
hydraulic rams, and has reference more particularly to, the feed, or supply, to the
said ram, and its object is to obviate or to lessen the amount of waste water
escape.
In order to more clearly explain this my invention I have appended hereunto an
illustrated sheet of drawings upon which are figures and numbers of reference
similar numbers referring throughout to the same thing or part.
Fig. 1. is a general side view of this my improved mechanism.
Fig. 2 shows the mechanism as arranged to suit a modified form of valve.

page_text: A storage of water is made from time to time, or continuously, in a tank or
other convenient reservoir 4. Leading from the lower part of this reservoir is a
conduit 5 to the ram, which latter is not shown. At the mouth of this conduit is
placed a valve 6, which may be counterweighted at 7 and contiguous to this valve
are arranged suitable guides 8 to receive or control a rising and falling float 9.
When the reservoir is empty the float 9 rests upon the valve 6 and keeps it or

is attached a cord, chain or rod, capable of an upward and downward movement,
and at a suitable point thereon is placed a lifting piece or arm 11, so that when
the float 9 reaches a certain point it lifts the plate 11 and with it the valve 6...
I find that when the valve has thus been opened but a little, by reason of its
being balanced at 7, it immediately yields to the rush of water and opens
quickly. This sudden rush of water effectively puts the ram into immediate
action. Having used most of the water in the reservoir, the float has by this time
fallen so as to again secure the closing of the valve as before while the recharging
takes place.

In Fig. 2 I have shown how a slideway valve may be used instead of a hinged
valve, both forms of valves being in themselves common in use for ordinary
purposes.
12 is a
In this case I utilize the valve spindle 10* in place of the before mentioned

of the float 9. Upon the spindle 10" is carried the lifting piece 11°.
spring which is attached at its lower end to the pipe 5* or other suitable fixture.
This spring 12 is furnished with the arm 13 which takes underneath the off set at 14
on the spindle 10%. 15 is a bar secured at 16 whose forward end is made to press
upon the spring 12 when the float 9 descends, and' thereby withdraws the arm 13
from the off set 14 on the spindle 10. 17 is a fence against which the spring 12
may rest to prevent its being pushed too far by the bar 15.
.
It will be now seen that its action is similar to that before described: -As
seen the valve is open and the flow passing through the pipe 5* the said valve
being supported partly by the buoyancy of the float and by the arm 13 lying
beneath the part 14. As the water in the tank lowers however the float descends
and commences to act upon the bar 15 which latter in its turn acts upon the

resistance so that a considerable portion of the buoyancy of the float is
Deutralized for awhile, until its accumulation overcomes the spring, and releases
the arm 13 from the catch 14, when the valve would close rapidly and shut
off the supply to the pipe 5ª. As the water in the tank again accumulates
the raising of the float is somewhat resisted by the spring 18 placed between
it and the lifting piece 11, and consequently the upward force becomes
sufficiently strong before the spindle is moved that when motion commences,
it rises with a rapid motion and permits a rush of water through the pipe 5
which effectually puts the ram into action. A weight 19 may be added to the
valve if necessary, as I find it to be an advantage. I am aware that floats have
been used in tanks or reservoirs of this or similar kinds to open and close the valves
leading to the ran, but in such cases when the float begins to rise, the passage of
water through the. pipe is so slow and gradual in its increase as not to put the
valve of the ram into action, consequently a great deal of water merely passes
through the ram to waste unless the valve is started by hand which has
generally to be done. In this my improved arrangement however the sudden
opening and closing of the valve by the mechanism as explained effectually
prevents such waste.
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.

constructed and operating substantially as described and shown in Fig. 2.
(3.) The general combination and arrangement of parts constituting these my
improvements by which the valve leading to the hydraulic ram is automatically
set in motion by a sudden rush of water thereto, such valve being also closed
when water supply reaches a certain low point all substantially as set forth and
illustrated.
