A LONG FELT
WANT SUPPLIED.
The Mitchell Pump and Irri-
cation Machine.

draulic Engine is for high pumping
TO raise water on the higher mesa
lands fifty to two hundred feet
above river level-By water power
The only practical power that
can be used for irrigation purposes,
no engineers, no fuel, also to avoid
| the construction and maintainance
of long and expensive ditches-In
construction the machine is solid
and durable, the mechanism is SIM
pie, automatic and positive, with =
minimum Of friction and wear,
economical in operation and posi-
tive in results, requiring but little
attention.
The structural work of standard
sized machine consists Of timber
frame work feet wide at ends, 8
feet wide at center, % feet long and
Z feet high. On top Of and the full
length of the frame, a fume or tank
feet wide and Is inches deep-mak-
ing the total heighth Of the machine
8l-2 feet. In this fiume or tank
water must be supplied for power and
pumping. This may be done by
ditch, fiume or pipe line rs conditions
may warrant. The mechanism con-
sists of two walking beams 81 feet
long; one water wheel feet in diam
eter; one balance wheel 8 feet In di-
ameter; pumps Of size required;
4 valve boxes attached to flume;
self dumping buckets. These buckets
are attached one to each end Of walk
ing beam, are almost half-circle In
shape and are SO balanced that they
dump very quickly and easily. The
walking beams are hung In the GEN.
ter OH rocker shaft; on each side Of
shaft or center, pump rods are con-
nected to beam making rocker shaft
the fulcrum for each pump. Thereby
making walking beams lever of the
first order for each pump.
The water wheel is connected to
the balance wheel by sprocket chain.
The balance wheel is connected 70
walking beams by crank and pitmsn
rods, acting as = governor, controlling
travel of beam and length Of stroke
sssists in velocity and In ntainin
an even motion.
At ends Of hume or tank on each
side located directly over ends Of
beam and self dumping buckets,
there is projecting box provided
with valves In the bottom Of box.
These valves are operated by rods
connected to walking beam, making
them automatic and positive. When
one end of beam raises to box, valve
is opened, the bucket filed with
water Of sufficient weight to over bal
ance resistance Of pumps and weight
of water in discharge pipe, forcing
that end Of the beam down and the
other end up, opening valve at that
end. While one bucket is filling the
other is dumping; while one pump is
discharging the other is charging,
and SO on encycle, producing a con-
tinuous flow Of water.
The valves are adjustable; the
power and speed of the machine can
be regulated by simply moving the
collar on the valve rod to open valve
more or less as desired.
The principle of this machine is
one of leverage. The walking beam
is the lever, the rocker shaft is the
fulcrum and the pump resistance the
power to lift; the water In the self
dumping buckets the power or weight
to over balance resistance of the
pumps and weight of water In the dis
charge pipe and lift 1t.
The water wheel is connected to the
balance wheel by sprocket chain and
geared down to one revolution to four
of the balance wheel thereby con-
serving the water.
This wheel may be of the over shot
style or of the turbine type and will
generate as much power as 1t is pos
sible to get out of q wheel or rotary
device with water at that height.
In addition to the power Of the
water wheel there is all the leverage
Of a 2l-foot walking beam. Leverage
is an old and recognized principle of
power. There are but two other ap-
pliapces by which it Is possible to ex-
ert more force or power than the
lever; these are the screw and wedge.
As the principle Of my machine is
one Of leverage, 1 depend largely on
the walking beam for power. a
water wheel Of whatever type 1t may
be is only a lever in circular form.
1t derives its power from the weight
Of the water being applied on the out
side OF the wheel. The amount of
leverage depends on the diameter of
