SECTION OF THE NEW PUMP.
Professor Charles A. Lurth, OF st. Louis,
was selected, and with some notifications
and changes. the machinery was put up
by H. a. Ramsey q Co, OF Baltimore.
The water-wheel is a vertical partial iur-
bine. . feet, u inches in diameter, peri
meter ~ inches wide buckets cOncdve
and q inches deep. The wheel revolves
vertically. Water is brought TO the wheel
by a fume five feet in diameter, and con-
nCCted by 81 gOOSe-ncck bend, WITH a
large guide chamber and dffuser at tne
base of the wheel. so as TO deliver the
water at right angles TO the buckets and
acts on about one-eighth of the circum-
ference at once The buckets and dlffuscr
are so shaped as TO lose the water as
quickly as possible after its action upon
the wheel Upon the shaft are three
crank arms. set at an angle OF l20 degrees
TO each other. and OF such length as 10
make six foot stroke OF plunger; they
are so proportoned that the moment one
pump ceases TO deliver, another com
mences, therefore the revolution is per-
fectly uniform.
DIAMETER OF THE rUMrs
The pumps are sirtgle-acting. vertical
plunger pumps, fourteen inches In diam
etor; each pump is supplied with three
cornish valves, suction. intermediate, and
discharge. The pumps are. connected by
20-inch diameter branches with a D.
inch suction main. charged under 20
foot head. and deliver into 3)-inch main,
passing under the fore-bay, and rising by
a gradually ascending grade. leo feet 10
the new reservoir There are three
wheels and three pumps 10 each wheel.
each set having a capacity OF 100000
gallons, or a total capacity OF 1900, 900
gallons in twenty-four hours. At their
maximum rate the wheels make 20 revo-
buttons per minute, and require 2s5 cubic
feet OF water per second. The water ne
cessary TO run the pumps Is discharged
into the Richmond level of the canal
and Is again used by several manufac-
tories and mills in the city

II will be seen from the above descrip-
ton, that the pumping machinery Of
Richmond is OF various designs. At the
upper station there are three vertical
partial turbine wheels. with single act

Duplex Compound Steam Pump. At the
lower station there are six old-fashioned.
low-breast water-wheels, working six
double-acting horizontal piston, pumps,
and Jonval turbine wheel working two
borizostal double acting piston pumps
The Guild and Garrison steam pump has
been sold. The pump-mains are so ar
ranged or connected that one or both
plants can be used to supply the higher
reservoir. or the lower reservoir can be
filled from the new reservoir.
The city distribution Is divided into two
services. The high service is supplied
from the rev reservoir, the low service
from the old reservoir The daily con-
sunaption Of the high service amounts to
100000 gallons. the low service TO $500.
