Improvements in Automatic Valves for Controlling the Exit of
Water or other Liquid from a Vessel, Pipe, or other Source.
SAMUEL HENRY ADAMS Hydraulic Engineer, Peaseholm Green York, and
5 and 7 Old Queen Street Westminster London do hereby declare the nature of
this invention and in what manner the saine is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in automatic valves for controlling the
For the purpose
exit of water or other liquid from a vessel, pipe, or other source.
of my invention I use a mushroom valve, spindle valve o .other of similar type by
preference, this valve is so arranged that the pressure of liquid tends to keep
it closed against its seat and it is opened by a weight of liquid by preference,
excited in a contrary direction overcoming the pressure I prefer to cairy a spindle
attached to the valve above the body in which this valve is placed and connect
this spindle either direct to a bucket or to a lever o lovers to which a bucket is
connected.
In one of my apparatus this lever is held in place by a bracket and at one side
of the lever I place a counter weight and at the other a bucket or vessel provided
with means for employing the same by tipping or otherwise-the weight being so
proportioned that by it the valve is held up to its seating or I may sometimes use
a spring arrange a supply of liquid to feed the bucket attached to the lever and
the weight of liquid in this buchet shall at the required moment overcome that of
the counterweight and the pressure of liquid on the valve and the bucket and its
contents shall descend actuating the level with which it is in connection and shall
depress the valve spindle opening the valve itsell and allowing the exit of liquid
from the resei von vessel main or other source of supply. Now the liquid which
has filled and by its weight caused the bucket to descend will presently cause it to
overturn being overbalanced by addition of liquid or it is syphoned or otherwise
emptied out, in some cases a valve being used-the bucket is then brought back
into position by the counter weight at other end of lover or by spring or other
contrivance and the valve is closed against further passage of liquid until the
operation is again repeated-the supply to the bucket thus governs the time at
which the valve 18 opened and also the duration of time during which the valve
Instead of the
remains open and thus also the amount of liquid passed through
lever and bucket I may use a weight or bucket upon the valve spindle in which
case 1 use a sping to keep the valve closed against the valve seat.
Under certain circumstances the positions of the counterweight and bucket may
be reversed and the valve closed against the pressure of liquid but I prefer to
construct my apparatus as now described. Other forms may however be adopted
to relieve the bucket of its load or to put the lever out of equilibrium.
Reference to my drawings will explain my meaning fully.
Fig. 1 Sheet 1 shews tho valve A kept closed by the pressure of the liquid in
supply pipe B. The pressure is sufficient to hold the bucket D in position. The
supply pipe Es led over the bucket and tap F iegulates the flow to bucket. Now
when this bucket is sufficiently full its weight causes it to descend and acting
upon the lever G the valve A 18 forced open and liquid passes directly through
the valve from B to H the outlet until such tune as the bucket D still filling by
liquid or other suitable substance becomes overbalanced and discharges its contents
into the receptacle J or ita contents may be withdrawn by other means when the

page_text: bucket free of its load is again returned to its position by the pressure of liquid
supply in valve and the operation repeats itself automatically being regulated as
to time of discharge by the passage of liquid through tap F.
Fig. 2 shews my valve closed partly by weight K which acts as a counterbalance
to the receptacle or bucket I This receptacle is fitted with a syphon M1 and
in operation the valve A is held closed against its sent until the liquid filling the
receptacle L from any suitable source counterbalances weight K and pressure on
valve from B and descending causes the valve A to open holding it open until the
liquid still entering Lises sufficiently high to pass through and start the syphon M1
and the latter withdraws by syphonage the contents of the receptacle L which
now lightened of its load returns to its former position and agam the valve is held.
closed. Here it will be apparent that a valvo on other contrivance might be used
to allow the water to pass from vessel L and the same applies in the other figs.
shewn.
Fig. 3 shews the valve closed by the weight Kand liquid pressure above valve.
It is opened by the bucket D being sufficiently weighted by liquid to descend and
after its descent still filled until it overbalances itself emptying its contents when
the valve becomes again closed. A is the valve B the pressure main and II the
outgo. The arrows in every case shew the course of water.
Fig. 4 shews my valve A held closed partly by pressure from B and partly by
the spring N. It will be seen that the bucket D is connected to the valve spindle
aud in descending acts duectly upon it. The requisite weight in this bucket will
cause it to descend and open the valve and the required additional liquid will
cause it to upset and thus being freed from its contents to return to its former
position.
Fig. 5 shews my valve A held in position partly by the pressure from main B
and partly by the weight K. When the bucket D becomes full it will descend and
open valve and with the additional inci case of liquid it will overturn and dis-
charging its contents into the vessel J will return to its former position. I form
an orifice at O to damn the liquid from J and I form a bend at P in order to create
a trap or water seal between the outgo pipe II and its connections and the
main B and its connections to avoid any contamination of the contents of the onu
side by those of the other
n
Fig. 6 shews my valve so arranged that it is closed by the weight of the liquid
in bucket and that the valve is open during such time as the bucket is empty
Fig. 7 Sheet 2 shews my valve as in Fig. 5 attached to and in combination
with a closed reservoir V and this reservoir may be supplied by a main T or pipe
or other somice of inferior capacity to the outgo H and is so arranged that having
become gradually filled its liquid contents may be liberated much more rapidly
and with considerable force through the outgo H. To ensure this I attach
my valve to the reservoir V and to allow the admission of an to the reset voit nt
the moment of discharge connect a pipe at or near its summit and I close thi
pipe by a valve R which is operated by the same movement which closes my
valve A. In this case when the bucket D descends it will raise the weight K
from its seat upon my valve K and allow the entry of air thus to the reservon.
It is clear however that this admission of air may be brought about by other
contrivances.
Having now particularly descubed and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claun is
let. The use of a valve in combination with a water main or other pressure pipe
wherein the water pressine shall hold the same closed and a bucket or vessel
descending by weight of liquid or other body therein and so connected to the
valve that the latter shall open and so remain until the bucket or vessel shall be
elieved of its contents and shall then allow the water pressure to exert itself upon
valve closing the same and preventing further passage of liquid.

page_text: 2nd. The use of a valve closing against the pressure of liquid in a main or
other source duectly or indirectly the valve being operated by a level or other
attachment by the weight of liquid stored for that purpose and liberated after it
shall have operated the valve.
3rd. The use of a tipping bucket in combination with a valve used for the
purpose of first opening a valve and secondly of governing the period during
which the valve shall remain open or of a vessel substantially for the same purpose
emptied by valve syphon or other means.
4th. The use of a closed reservoir and means of admitting an and water thereto
in combination with my special valves shewn on their equivalents.
5th. The general ariaugement and design of the various apparatus shewn in my
accompanying drawings.
6th. The use of apparatus as described and shewn though differing from
substantially the same and for the same purpose.
