Improvements in Apparatus for Lifting Sewage and other Liquids.
FREDERICK WILLIAM LACEY, of Alum Chine Lodge, West Cliff Road, Bourne-
mouth, in the County of Southampton, Civil Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improved air valves for admission and release of
compressed air in combination with an automatic ram or ejector.
In practice it is found that the air valves as generally used get out of order
after they have been working a short time, they are also liable to jam, and the
parts are complicated.
The object of this invention is to make a valve which will not so readily get out
of order, which is not so liable to jam, and which is also of simple construction.
The apparatus complete, consists of an egg or spherical shaped vessel having
sewage inlet and outlet valves at the bottom, of suitable construction. These
valves are placed similar to those under the ram of a pump and their action is
precisely the same, except that compressed air does the forcing instead of a ran
or piston in the case of a pump. At the top of the vessel there is valve gear
which is made to act automatically by means of a float or weight and bell
arrangement inside the vessel.
In order to ensure a quick movement with the valve, I have a lever and weight
which is made to rise with the sewage inside the vessel and when a given height
is reached, the weighted lever overbalances and quickly turns the valve, and
compressed air is admitted to force the sewage out to the height required. A
similar action is performed when the vessel is nearly emptied of sewage, thus
turning the valve the other way to allow exhaust.
The improved air valve is formed by a piston working in a cylinder. There is
an inlet and an outlet, which are opened and closed as the piston passes. The
piston rod is connected by levers to take action by the weighted lever, and the
lever worked by float inside the vessel.
My improvement consists of a combination of these and it is obvious the
apparatus may be used for lifting or forcing any kind of liquid.

mouth, in the County of Southampton, do hereby declare the nature of this
[Price 8d.]

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My said invention relates to improved air valves for admission and release
of compressed air in conjunction with an automatic ram or ejector.
In order that my said invention may be fully understood I attach drawings
hereto Figure 1 represents a sectional elevation of the automatic ram upon
line A, B, of Figure 2-Figure 2 represents the side elevation of the automatic
ram.
In Figure 1 the spherical shaped vessel is shown in section at a. The inlet is
at b with a suitable leather faced valve at c connected to the branch piece d.
The outlet is at e having a similar valve at f. The float g is devised with inverted
cup similar to a diving bell. The cup h acts as a weight to bring the valve gear
down. The cups are attached to the rod j which is connected with the piston
valve k, the piston having motion between two stops and m upon the rod.
The cylinder for piston is at having a gland p for the rod to pass airtight.
The lever q is worked by drag link through the rod. Upon the same axle as that
of the lever a bell crank lever is placed with weight r at one end, the other end
of which is made with turned ends to form a lip for, and to catch the lever q.
The brackets is made to guide and support the end of rod--and the bracket t
is in the form of a quadrant and made to stop the motion of the levers and piston
valve at each end of stroke.
When the ram is at work the sewage will enter at b, pass into the vessel a and
when the level of the inverted cup 9 is reached the said cup and rod will rise
with the sewage until the collar m is in contact with the piston k, and the lever q
has moved the lever carrying the weight r into a vertical position. The sewage
will continue to rise inside the ram causing the weight to overbalance, and in
falling over moves the lever and the piston valve attached thereto, so as to allow
compressed air to pass from the pipe u across the piston cylinder and through
the pipe w into the ram. The upper branch on pipe w is to allow equal pressure
at the ends and centre of piston. The compressed air upon entering the ram
forces the sewage down and out through the outlet valve f and bend e, until the
level of the sewage in the ram begins to get below the cup h, which latter will
then act as a weight and drop with the sewage bringing the rod with it, until
the lever, actuated thereby reverses the piston valve and thus cut off the com-
pressed air from pipe u, and open the exhaust pipe v which latter allows the
compressed air to escape from the cylinder, when the sewage will enter again
at band the operation as above described will continue to repeat itself.
I thus have a simple piston valve worked by levers acted upon by cup float
and weight.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The combination of a piston valve worked by float and weight and levers in
connection with an automatic ram or ejector for the purposes specified as described,
and illustrated by drawings annexed.
