An operating-crank II may be attached to
the outer end of the shaft G, or said shaft
may be provided with any other suitable de-
vice by which it may be operated by hand or
5 power, as desired.
The cap-piece F may be provided with seg-
mental slots or openings f' f', covered and
closed by transparent plates 2, of glass or
other suitable material, through which the
io interior of the pump mechanism may be in-
The bottom or base-piece, piston, middle
piece or member, and top or cap-piece are all
preferably of flat circular or disk shape, hav-
15 ing the relatively-arranged segmental slots
or grooves, as above described, and assem-
bled together in parallel superposed positions,
as shown, whereby the whole forms a simple
and compact pump device which will operate
go with great power and effectiveness.
The operation and advantages of my inven-
tion will be readily understood. The water
enters at the inlet e into the segmental groove
or passage d of the middle piece, and as the
25 piston is turned or revolved by means of its
shaft the hinged valves rise at the initial end
of the slot d and force the water through the
same and the outlet f at the terminal end of
the slot, when the hinged valves close and
30 pass under the middle piece D until they
again reach the initial end of the slot d. The
rotary operation of the piston and its hinged
valves is adapted to force the water with great
power, so that it will throw a stream for a
35 considerable height or can be generally used
for any desired purpose for which such mech-
anism is adapted.
Having thus described my invention, I
claim and desire to secure by Letters Pat-
1. An improved pump of the class described,
comprising a closed casing interiorly having
a segmental groove or channel in its base por-
tion and a relatively-arranged segmental pas-
45 sage above said groove or channel, water in-
let and outlet connections at the respective
ends of said passage, and a rotary piston ar-
ranged between said groove or channel and
said passage and carrying angular valves op-
erating upon a fulcrum and embodying di- 50
vergently-projecting arms adapted to project
respectively into said groove or channel and
said passage when the valve turns upon its
fulcrum, substantially as and for the purpose
set forth. 55
2. An improved pump of the class described,
comprising a closed casing embodying a base
having a segmental groove or channel in its
top surface, a middle piece having a rela-
tively-arranged segmental slot or passage pro- 6o
vided with water inlet and outlet connections
at its respective ends, and a cap - piece or
cover, in combination with a disk forming a
rotary piston inclosed within said casing be-
tween the base and middle piece and carry- 65
ing angular hinged valves embodying arms
adapted to project at its opposite sides and in
relation to said channel and said passage,
substantially as and for the purpose set forth.
3. An improved pump of the class described, 70
comprising a closed casing embodying in su-
perposed relation a base having in its top
surface a segmental groove or channel with
guide-inclines at its ends, a middle piece hav-
ing a relatively-arranged segmental slot or 75
passage provided with water inlet and outlet
connections at its respective ends and with a
guide-incline at its terminal end extending
with relation to said channel, and a cap-piece
or cover, in combination with a rotary disk 8o
forming a piston and carried upon a shaft
transversely mounted in said casing, said pis-
ton having mounted in it right-angular hinged
valves the arms of which are adapted to pro-
jectat opposite sides and operate in said chan- 85
nel and said passage, substantially as and for
the purpose set forth.
In testimony whereof I affix my signature
in presence of two witnesses.
