THE NEW PUMP.

With Water Whe,, all The other Pansps
are shut Do,vn, and Is Only Run at One
Hall its Capacity. too.
Yesterday the new 100000 gallon
capacity pump was started up for general
business, and is now supplying the entire
city with water, the other pumps having
been shut down. It does the work re-
quired of it easily and noiselessly and
is only run at half its capacity, throwing
100000 gallons per diem. On Monday
three of the old pumps will be started
again and run at a very slow speed, while
the remaining two pumps will be taken to
the East Side pumping station.
As has been mentioned in these col
umns, this new pump is tn invention of
Chief Engineer Waters, of the water board,
and was manufactured by Streethman
Bros. The cost was $500, while a pump
of the same capacity of any other make
must have cost about three times as much,
besides occupying nearly three times the
space in the water works. So, all in all, it
is estimated that the city has saved up
wards of $4,000 in the manufacture of
this Waters pump, which is far superior
in almost every particular to any other
by the inventor, who will beyond doubt,
amass fortune from the same.
Chief Engineer Waters gives the follow,
ing detailed description of the pump,
which must prove of interest to our citi
zens: The pump receives its power from
sixty-inch water wheel of 500 horse pow
er, to which is attached an upright shaft
six and one-half inches in diameter. The
pump rests directly over the water wheel,
the shaft making connection with it in the
| center of the machinery. 1t consists of
five iron columns thirty seven inches IN
diameter and eleven feet in height, the
| top of each being in the form of a dome.
| The columns are placed in circle infthe
center of which stands the upright shaft.
Each column is divided into three cham
bers-a lower, central and an upper
| chamber. Within the space circum-
scribed by the circle of col
umns are two circular pipes
placed horizontally, one above the
other. The size of these pipes is twenty
inches, and they are connected with the
columns by connecting pipes as follows:
| The lower one, with each Of the lower
| chambers, and also with the suction pipe;
while the upper is connected with each of
the upper chambers and with the discharge
pipe. TO more clearly locate these two
| pipes, it may be added that they are re-
| spectively on the same plane, horizontally,
with the upper and lower chamber of the
columns.) The movable part of the ma
| chinery connects with the stationary part
as follows: The plungers and connecting
rods play horizontally between the central
chambers of the columns (ths plungers en-
tering the chambers) and crank on the
upper end of the water wheel shaft, the
said being exactly midway between the
two circular pipes and coinciding with a
line drawn perpendicularly Though TIE
centres of both the circles formed
by the circular pipes. Each connecting
rod Whose outer end is attached to its
plunger) is connected in the center to the
crank-eye on the shaft crank and oscillates
on pinion as the crank revolves. The
crank-eye is also fastened rigidly to an ex
ira connecting rod and plunger-called
the ''idler"-the latter doing no service
except to keep the sc! Q" 10 position as the
| crank revolves.
Nov when the shaft and crank are put
in motion the plungers-each in turn-are
forced in and out of the central chamber
| by the connecting rods. AS the plungers
are drawn out the water is sucked through
the suction pipe into the lower circular
pipe and thence into the lower chambers,
passing upwards through valves
| just under the plungers, enter
ing the central chambers. AS the plungers
are forced back into the central chambers
the valves below close and the water is
forced into the upper charlottesville
| domes of which act as air chambers
thence into the upper circulars pipe and
finally into the discharge pipe.
At every revolution of the shaft all of
the five plungers perform this service, and
in an instant seventy-fve gallons of water
pass through the pump, With 100 revolu-
lions of the shaft $4,000 gallons pass
through which occupies one minute of
time. 1t Is the intention to place three
other pumps of a similar pattern and
capacity in the room where the new one is,
to be arranged in rectangular form.
