bracing the blades 15 and preventing vibra-
tion of the shaft 6 I provide one or more
guides 18, consisting of a pair of plates fas-
tened one on each side of the blades at suit-
able intervals, each plate being provided with
a semicircular socket 19 for the reception of
the operating-shaft.
In operation motion is imparted to the shaft
6, which causes a partial vacuum in the tube
10 or casing and forces the water upwardly in
contact with the first propeller. As the fluid
leaves the first propeller its rotary motion is
changed by contact with the wings or blades
15 and said fluid forced upwardly in a straight
[5 line until it reaches the deflectors 16, at which
point the column of water will be deflected
so as to strike the next propeller tangentially
and in a direction opposite to the direction
of rotation of said propeller. As many pro-
20 pellers may be used on the operating-shaft as
desired, the action of the water as it enters
and leaves the propellers being the same in
all cases. The cylindrical casings 12 prevent
the water and sand from being thrown out-
25 wardly in contact with the casing 5 and also
form a means for supporting the deflecting
wings or blades.
By having the radial blades extend the en-
tire distance between the propellers they not
30 only serve to maintain the integrity of the
column of water, but cause it to travel up-
wardly in a path substantially parallel with
the axis of the pump-casing, thereby reduc-
ing the amount of friction, and consequently
35 increasing the efficiency of the pump.
While 1 have shown and described the wings
or blades as being disposed substantially par-
allel with the operating-shaft, it is obvious
that said blades may be arranged at any angle
40 or inclination with relation to the shaft de-
sired.
Having thus described the invention, what
is claimed is-
1. In a pump of the class described, a cas-
45 ing, a propeller, and means for checking the
rotative movement of the column of water and
guiding it in a direction approximately par-
allel with the axis of the casing and subse-
quently deflecting the water at an oblique an-
5c gle in a direction the reverse of that in which
the propeller is rotating.
2. In a pump of the class described, a cas-
ing, a plurality of propellers, and means for
directing the column of water in a direction
55 approximately parallel with the axis of the
casing between successive propellers and for
subsequently deflecting said column at an
oblique angle into the path of each propeller.
3. In a pump of the class described, a cas-
6o ing, a plurality of propellers, means for di-
recting the column of water in a direction ap-
proximately parallel with the axis of the cas-
ing between successive propellers, and curved
deflectors for changing the direction of the
65 flow of water after it leaves each propeller.4. In a pump of the class described, a cas-
ing, an operating-shaft, a plurality of pro-
pellers carried by the shaft, a protective cas-
ing surrounding said propellers, and means
for directing the column of water in a direc- 70
tion approximately parallel with the axis of
the pump-casing between successive propel-
lers and for subsequently deflecting the col-
umn at an oblique angle into the path of each
propeller. 75
5. In a pump of the class described, a cas-
ing, an operating-shaft, a plurality of spaced
propellers carried by the shaft, and longitu-
dinally-disposed blades extending the entire
distance between said propellers and provided 8o
with terminal curved deflectors for directing
the column of water in a direction the reverse
of that in which the propeller is rotating.
6. In a pump of the class described, a cas-
ing, an operating-shaft, a propeller consisting 85
of one or more flights secured to the shaft, a
protecting-shell for the propeller, and a plu-
rality of longitudinally - disposed wings or
blades secured to the protecting-shell, said
wings or blades having their opposite ends 90
curved to form deflectors.
7. In a pump of the class described, a cas-
ing, an operating-shaft, a propeller carried by
the shaft, a protecting-shell surrounding the
propeller, and a plurality of wings or blades 95
each provided at one edge with a flange se-
cured to the protecting-shell, said wings or
blades having their.end portions curved to
form deflectors.
8. In a pump of the class described, a cas- 100
ing, an operating-shaft, a propeller carried by
the shaft, a protecting-shell surrounding the
propeller, radial wings or blades secured to
the protecting-shell, said wings or blades hav-
ing their end portions curved to form deflec- 105
tors and their intermediate portions arranged
substantially parallel with the operating-
shaft.
9. In a pump of the class described, a cas-
ing, an operating-shaft, a propeller carried by 11o
the shaft, a protecting-shell surrounding the
propeller, wings or blades arranged longitu-
dinally of the shaft and radially of the casing
secured to the protecting-shell, said wings or
blades having their terminal portions curved 115
to form deflectors.
10. In a pump of the class described, a cas-
ing, an operating-shaft, a propeller secured to
the shaft, a protecting-shell surrounding the
propeller, wings or blades having their termi- 120
nal portions curved to form deflectors secured
to the protecting-shell and guides carried by
the wings or blades.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in 125
the presence of two witnesses.
