JAMES C. WALKER, OF WACO, TEXAS.
WATER-WH EEL.
SPECIFICATION forming part of Letters Patent No. 467,840, dated January 26, 1892.
Application filed June 20, 1891. Serial No. 396,999. (No model.)To all w hona it imay cozcer:zz:
Be it known that I, JAMES C. WALKER, re-
siding at Waco, in the county of McLennan
and State of Texas, have invented a new and
5 Improved Water-Wheel, of which the follow-
ing is a specification.
The object of my invention is to provide a
water-wheel in which the energy of the water
shall act upon a series of peripheral buckets
to on a principle of hydraulic pressure in con-
tradistinction to that of mere impact and mo-
mentum; and to this end it consists in the pe-
culiar construction and arrangement of parts,
which I will now proceed to fully descri be with
15 reference to the drawings, in which-
Figure 1 is a vertical section of the wheel,
taken at right angles to its axis. Fig. 2 is an
inside view of the case. Fig. 3 is a vertical
section of the wheel, taken longitudinally to
20 the axis; and Figs. 4, 5, and 6 are details of
the valve mechanism.
In the drawings, Y Yis the outer case, which
is sustained upon a suitable base by means
of legs or standards L. The right-hand por-
25 tion of the case, as shown on the drawings,
is constructed with a semicircular chamber
extending a little more than half-way around,
beginning at P P' and extending to P2 P3, the
balance of the chamber being open. The in-
30 ner perimeter of this semicircular chamber
P' P2 of one half-section approaches the same
wall of the outer half-section just close enough
to leave a slot through which the web of the
water-wheel may pass, the joint being made
35 tight at this point by packing laid in a groove
in this inner wall and bearing against the
web of the wheel. The other portion of the
case is open and need not closely fit the wheel,
and hence may be made of any desired shape.
40 F' is the inlet-pipe of the wheel, and G is
the outlet. The inlet-pipe is cast upon or at-
tached to the case and extends around about
two-thirds of the semicircular chamber, and
has four inlet-ports F F' F2 F3 opening into
45 the same. Within the case there revolves a
wheel Z, which consists of a thin disk with a
series of cup-shaped or conical buckets D on its
periphery, sustained by webs or flanges r, hav-
ing inclined outer edges. As the wheel revolves
50 in the case said wheel receives the water upon.
its buckets D, the water entering through the
ports F F' F2 F3. Gates or abutments a b anda2 b2 prevent the water from escaping back-
wardly and compel the water to act with a hy-
draulic pressure upon the buckets of the wheel a5
within the closely-fitting semicircular cham-
ber. These gates are hinged to the outer pe-
ripheryof thecase,and theirfreeends rest upon
the inner periphery of the case and outer edge
of the wheel, the inclined flanges or webs r of 6o
the wheel causing these gates to ride up and
over the buckets D as they pass the gates.
The gate a b is constructed as shown, and fits
closely the chamber with a tight joint, so that
while in this position no water can flow back 65
of it into the open part of the case. When
the bucket D passes one of these gates, the
said gate rises into its recess in the upper
portion of the case, as shown by the dotted
lines a b', (and also as shown by the fullline 7o
a2 b2,) and when the bucket passes the end of
the gate the latter falls back to its place. As
soon as this gate is touched by the inclined
flange r of the bucket, the port F (or F') is
closed by a valve mechanism hereinafter de- 75
scribed, and when the gate falls back to the
position a b the same valve mechanism opens
the port again and the water fills the space
in the chamber between the gate and the re-
ceding bucket of the wheel and adds its force So
to the said bucket, which now raises the sec-
ond gate to its recess, as shown at a2 b2. As
soon as the bucket passes theend of this gate,
the latter falls back to the position indicated
by dotted lines a2 b2, and this gate in this po- 85
sition prevents the backflow of water from
port F' and also from ports F2 F3. The prac-
tical point aimed at is to have one of these
gates in position a b or a2 b all the time-i. e.,
as the first gate is raised the second is closed, 90
and before the second gate is reached by the
incline of the bucket the first gate falls back
to a b, thus practically stopping up the upper
end of the pressure-chamber, and thereby
bringing to bear on the revolving buckets of 95
the wheel the hydraulic force of the water
entering through at least three of the ports.
In constructing the case of the wheel I may
make that portion in which the gate plays
square instead of circular and with the top 'co
or side removable to permit of access to the
'gates.
Referring to Figs. 4, 5, and 6, B represents
a slide-valvehaving an opening Ain the same
