Improvements in Pumps
I, ALFONGS MFUSER of Longwood, Orange County, Florida, USA,
Mechanic, do hereby declare the nature of this invention to be as follows
-
This invention relates to the provision in a pump of two an chambers which are
in communication with the delivery pipe, which latter between the two air chambers,
is provided with a check valve
the delivery pipe
As the pump piston rises the water or other fluid is forced into the first of the air
chamber, then up past the check valve into the second air chamber and then out of
At the end of the stroke of the pump piston the check valve
closes and takes the weight of the superincumbent fluid off the pump valve and
whilst the piston is descending the air compressed in the upper air chamber will
expand and force the fluid in an even stream from the delivery pipe

1, ALONGS MEUSER of Longwood, Orange County, Florida, USA,
Mechanic, 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 attachment for pumps by means of which power is
economized in two ways, first by enabling speed to be increased, and second by
decreasing jar and friction
In the accompanying drawing
Fig 1 is a side view of a pump having my invention attached thereto
Fig 2 is a sectional view of the attachment which consists of a primary air
chamber I connected by a suitable pipe 2 with the outlet of the pump 3 Said
pipe 2 is preferably horizontal and connects with a perpendicular pipe 4
Thus the
primary air chamber 1 is connected with pipe 4 Pipe 4 is provided with a
secondary air chamber 5 suitably connected The outlet of the chamber 5 is above
the top of the chamber 2 Pipe 4 is also provided with a check valve 6 which is
Jocated between the connection of air chamber 5 and the connection of air
chamber 1 This valve allows the fluid to pass up, but does not permit its return
The pipe 2 may be provided with the draw off cock 7 As the piston in the pump
rises, the water or other fluid is forced into the primary air chamber 1 then up
through the valve 6 into a secondary air chamber 5 and up out of the pipe 4 As
the fluid enters the air chambers the air therein is compressed At the end of the
stroke of the piston the check valve 6 closes and takes the weight of the super-
incumbent water off the pump valve and while the piston is descending the air
compressed in the secondary air chamber ɔ will expand and force the water in an

page_text: even and continuous flow out of the pipe 4
As there will be less water weight on
the air in chamber 5 expansion will take place first in that chamber, and when this
pressure is sufficiently exhausted the valve 6 will rise and the expansion of air in
chamber 1 will act on the new supply of water furnished it by the return stroke of
the piston in the pump
This attachment may be applied to any kind of pump the one shewn in the
drawing being used simply as an example
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
An attachment for pumps consisting of a pipe adapted to connect with the pump,
primary and secondary air chambers connected to said pipe, and a check valve
located in said pipe between the connections of the said air chambers substantially
as described and shewn
