I SAMUEL HENRY ADAMS Sanitary Engineer of Monk Bridge York do hereby
declare the nature of my invention for IMPROVEMENT IN APPLIANCES FOR THE
INTERMITTENT DISCHARGE OF WATER OR OTHER LIQUID and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention consists of an improvement in appliances for the intermittent
discharge of water or other liquid and is a modification of my Patent N° 727 of
1881 I provide a syphon formed by preference of an inner tube figured A and an
outer shell B as shewn on accompanying drawing the lower end of A dipping into
a receptacle C having an outlet D such receptacle C being filled with water or other
liquid into which the lower end of A dips to any required depth thus forming a
water seal such seal confining the air contained in tube A This apparatus I fix in
a tank or chamber of masonry iron or other suitable material when its action will
be as follows
The tank or chamber filling with liquid the body of air contained in A will be
confined but as the water rises in tank and as the pressure within A corre-
spondingly increases air will be expelled at intervals thro' the water seals at C
Sufficient air will however be retained in the tube A. to hold back the water in
tank which will not waste thro' the syphon until at a height above it equal to the
depth of water seal Upon this point being attained as the tank fills the water will
pass away thro the syphon until upon the sudden addition of water to the tank
and a consequent rapid rise the air within A will be overcome & forcibly expelled
thro' seal at C when the syphonic action will be immediately set up and the entire
contents of tank discharged thro the outlet D.
To prevent this water running to waste and to ensure an instant discharge of
syphon whether the inflow to tank be quick or slow I provide where necessary a
pipe in connection with A or B figured E this pipe having placed over its extremity
a cup F or similar arrangement such cap F being in connection with the bent pipe G
or its equivalent.
The dip or bend of pipe G is less than the dip of tube A into the trap C and the
height of bend G such that it remains filled with water or liquid.

page_text: As the tank or chamber fills with liquid-the receptacle or trap C and the pipe G
being filled with liquid-the air confined within A will be expelled passing up
tube E and escaping from cap F until the water still rising closes this means of
exit and confines the rest of the air within A the cap F is so arranged that the
requisite amount of air is secured within A As the water rises in the tank the
pressure again increases until when a given height above the tube A has been
reached the weight of water becomes so great that the confined air is forcibly
expelled thro' the weakest of the water seals viz that in the pipe G the imediate
syphon action is set up and the entire contents of the tank or chamber discharged
thro the outlet D After this discharge air is readmitted to the syphon through 1
the tube E and the vacuum in syphon broken and imperfect syphonic action
prevented the tube G is so arranged that it refills with liquid after its contents
have been ejected.
Where a quick inflow to tank is assured in certain cases I dispense with the
cap F and tube G terminating the pipe E in a bend H as shewn in Fig. 2 here the 1
air escapes to the required amount and the remainder is confined as before by the
rising liquid in tank after the discharge air is readmitted to the syphon breaking
the vacuum & preventing imperfect action it is not necessary to the working of
this syphon that the water seal at lower end of A should be deep it may be of
any depth or degree of shallowness desired nor is it necessary that the pipe E
should be either closed by a cap or bent down answering my purpose in certain
cases if merely left open at top or with any air opening in its side.
Fig. 3 and 4 shew other forins my syphon apparatus may take.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
I claim 1st The arrangement of pipe E in combination with the long limb of a
syphon such pipe E having an open top or being covered at its extremity by a cap
as G or it may be bent down as H. Fig. 2 or any equivalent arrangement.
2nd The arrangement of cap F and bent pipe G or their equivalent or a valve in
combination with pipe E connected to the long limb of a syphon.
3rd The arrangement of pipe E & cap F and bent tube G in combination with a
syphon such syphon having a deeper water seal at its longer limb than that formed
by the bent tube G the air pressure in syphon when water or liquid shall have
gained the starting level blowing through the water or liquid in G allowing the
syphonic action to follow, the tube G again refilling with liquid.
4th The arrangement of pipe E with cap F or its equivalent with a syphon for
the purpose of allowing the exit of air from within syphon up to a certain point
confining the remainder and afterwards allowing the ingress of air to break the
syphon action or partial vacuum.
5th The arrangement of the different appliances as shewn Fig. 1. 2. 3 & 4 & E
G F or their equivalent in principle though differing in conformity.
