A WONDERFUL PUMP.

was Seen at Brfdesburg-Fifteen Million
Gallons of water Day from 2O-inch
Pump.
A number OF gentlemen under the leadership
of Colonel Barton Ii. jerks, whose extensive
machine-shops have contributed so much to-
wards the prosperity and reputation Of our city,
were yesterday taken to Bridesburg in the mini
ature yacht Harold, the property of Colonel
William B. Mann, to note the operation of
newly-patented compound pump. Mechanics
have, from time immemorial, set their wits to
work to devise an appliance to raise water at
any elevation that should be simple in Its con-
struction, economical in its operation, and COM
parativey cheap in its first cost. All tnese
qualities are met in the, uncompncated
though marvellously powerful pump-ratner
elevator-which has been produced at the
works of Colonel jerks. The pump at work
Yesterday may be thus briefly described:-A
cast-iron pipe about 12 feet long and 20 inches
in side diameter, which stands upright in
basin of water, the lower end of it resting
upon an iron basket, or guard, to prevent stones
and the like from passing into the pipe. From
the upper end projects a nozzle to direct the
stream of water as it Is pumped up.
Through this cast-iron pipe is run a
about four feet, are placed cast-iron propeller
wheels, each of two blades with angular
pitch of sixty-ive degrees. Having described
this much, the reader will al once discover, I'm
his minds eye," the principle on which this
pump works. At the top of the steel shaft is
pull eighteen inches in diameter, and run by
10-inch belt at the rate of four hundred revolu-
tions to the minute, the motor being % horse
power engine. Thus it was, and much to the
astonishment of the party that yesterday
saw it, that these two propeller wheels, running
ut the speed we have mentioned, discharged
from the pump ten thousand gallons of lCdter
per minute, six hundred thousand gallons in an
hour, and nearly fifteen million gallons of water
per day, or just one-half of the amount supplied
by all the engine pumps in the entire water

for indicating the quantity of water raised by
the pump has paddle wheel 20 inches in diam
eteT, with worm gearing into an index wheel
with 160 teeth. The index wheel is revolved by
the passage of the current of water once in two
minutes and half, and in one minute registers
the passage of 4021 inches of water. The falls
is 101 inches in width, with an average depth
of So inches, showing the passage as stated
above of 10 098 gallons, or over 40 tons of water
per minute. But Colonel jerks has added
another, and striking Improvement to this
Invention.
He has avoided the great amount of friction
which would otherwise be caused by the weight
of the shaft and the propellers supporting
heavy column of water, by constructing at the
top of the pipe disc, upon which rests ring
of brass, and upon this rests another disc en-
bracing the outer periphery of the brass ring,
and which is permanently secured to the pro
peler shaft. By means of small donkey pump
water is forced between the two discs under suf-
fcent pressure to slightly separate them, so that
the top disc, propeller shaft, and column of
water are supported by the film of water be-
tween them, and thus the rotation of the pro-
peller shaft revolving on the water causes only
very small amount of friction.
There is in successful operation at Glen Car
bon Colliery now one of these compressed pro-
peller pumps The principle upon which it
works is Identical with that at work at Brides
Durg. 1t differs, however, in this:-Whllc the
inside diameter of the pipe is but eight inches,
its length is three hundred feet long, and of it

of 100 gallons per minute-the propeller lifting the
water to stationary wings or blades above IL, oy
which it is supported aud from which it Is taken by
the next succeeding propeller and so on until tne
water is discharged, thus avoiding all valves or COM
piicated machinery. The advantages claimed for

The advantages of this pump are thus sum-
First. Its great simplicity of construction, having
no valves and consisting OF but three pieces, pipe,
Second. Economy, costing much less than any
pump OF the same power.
Third. Its enormous power. The eight-nch pump

Fifth. 1t can be used either as lift or force
pump.
Sixth. 1t requires oiling, and is adapted for all
kinds OF mines, quarries, breweries, lighthouses OF
any place where water is an annoyance and II
especially useful for waterworks in towns and cities
as the water can be introduced by this apparatus al
less expense than by any other system.
Seventh Sand, mud, sticks, and other rubbish dc
not interfere with It's operations.
This pump is to be brought to the attention ol
Councils. One thing is certain, should 1t be
adapted to municipal purposes, that the cost
of maintenance would be remarkably small, in
comparison with our present heavy expenditures
to keep up a supply, while the volume would be
more adequate to our wants.
While the Bridesburg Manufacturing Com
pany have the entire control of the manufacture
of these pumps, the patent right belongs to the
Hydrostatic and Hydraulic Company of Penn
sylvania, chartered under the general laws oi
this State, of which company Colonel Barton II
jerks is President.
