Improved Means for Compressing Air for Raising Sewage or other
Liquids, and for other Purposes, and for Apparatus in connection
therewith.
I SAMUEL HENRY ADAMS Hydraulic Engineer Peaseholm Green York, 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:-
My present invention relates to modifications and extensions of my Patents
Nos. 6874-92, and 6378-94, wherein I shewed the use of a cylinder receiving liquid
to be raised and another cylinder from which air expelled by liquid pressure should
act upon the first named-forcing out the liquid therefrom up a suitable, outlet
pipe, the height of lift being governed by the height of the water pressure pipe on the
first named vessel and now I will proceed to describe in detail the inventions here
illustrated by the accompanying diagrams the different parts of which for ease of
reference are figured to correspond one with another.
At Fig. 1 Sheet 1 will be seen the flush tank B which discharges itself auto-
matically or otherwise to the pressure pipe E, by means of a syphon as B1 or
other valve-its outlet connected to E by branch as C. The cylinder F receives
the liquid discharge from B by pipe E the air contained in cylinder F being
expelled through air pipe H as liquid enters F.
When cylinder F is filled to the desired capacity its contents are discharged by
syphon G with outlet G 3 or a valve automatic or non automatic operates allowing
the liquid contents to pass away.
Now it is evident that if I can at the same time as the liquid from tank B
enters F induce an additional air current in pipe E I shall carry more air to F
and the result will be that I shall be able to pass by pipe H more air than the
actual amount contained by F before the liquid from B was delivered to it. To
effect this end I place a cone D or a series of cones D. D or other device by which
I cascade the falling water as shewn at Fig. 2 and 3 either at the junction of air
pipe A at Fig. 3 (this pipe A is in reality a continuation of E or a branch attached
thereto as A 2) or below the junction of vent pipe as Fig. 2. Now the cone or
other device breaks the water in falling and creates a cascade and the cascade
creates suction of air down pipe A to E and feeds the air to F in a degree greatly
in excess of the amount which would be fed in if as at Fig. 1 where the cones are
not inserted I may add any number of air feeders as A 1 Fig. 4 or of breaks or
cones as D1 on pipe E.
At Fig. 3 I shew the syphon outlet G which is sometimes used instead of a
valve to withdraw the liquid contents of F.
At Fig. 4 shew the air cylinder F with its tank B pressure pipe E
air pipe H and
At H 1. I shew a ball which floating on the rising liquid in F may close air
pipe H and thus prevent entry of liquid thereto.
The syphon G is also shewn, this syphon it will be seen has a very deep trap or
bend at its longer limb G 1 the object being to lock the air within the syphon
itself and by this means I am able, to use a syphon with comparatively short
top G4 where a tall top would be objectionable or impossible or inoperative, the
confined air in G due to liquid remaining in G 1 forming an air lock and preventing

page_text: 8th. The combination of three receptacles or vessels one containing air and the
other two containing liquid or matter to be raised and the air pipe connecting the
same.
9th. The use of valves automatic or otherwise directing the passage of air
from a pipe or cylinder to one or other vessel as desired for the purpose of
expelling by air pressure the contents of the said vessels as shewn at Fig. 6.
10th. The use of the float as Y rising and falling with the liquid supply to
cylinder I actuating the supply by tap or cock Z to tank B or direct to pressure
pipe E or E 2.
11th. The use of two or more cylinders from which it is desired to force liquid
or other matter in upward steps or stages in combination with outgo pipes coupling
the same, it being sufficient for my purpose that the expelling force used shall be
air under pressure however this pressure be obtained.
12th. The use of a pipe so arranged between a vessel charged with liquid and
another vessel into which it is desired to raise this liquid, that the said pipe serves
to convey the liquid from the lower vessel to the higher-and subsequently to
convey air from the lower vessel-which air acting upon the liquid in the higher
vessel shall be available as a power to force this liquid from this higher vessel
through an outgo pipe or shall force it to another vessel connected therewith as
before described shewn at Fig. 8.
13th. The combination of two or more vessels as I and R-with an intermediate
pipe which shall serve both for a liquid exit and to convey air pressure.
14th. The use of the water trap X which allowing the escape of air from a
vessel to which it is connected shall presently become charged by the rising liquid
in the said vessel and thereby stop further exit of air. This with the object of
utilising the air thus confined for the purpose of exerting air pressure upon the
contents of the same vessel and thereby expelling its contents up outgo pipe the air
then blowing water trap clear see Fig. 8.
15th. The use of a valve or tap automatic or non automatic in combination with
a vessel or vessels to allow or check or stop the escape of air therefrom that liquid
⚫ may first enter & afterwards be discharged by air pressure from the said vessel or
vessels as X Fig. 8.
16th. The use of the vessels described & shewn and the general arrangement
and design of the apparatus shewn & described or their equivalents though differing
in conformity, substantially the same & for the same purpose.
Dated this 9th day of January 1896.
