DUPLEX-WATER-WHEEL REGISTER-GATE.

SPECIFICATION forming part of Letters Patent No. 588,501 dated August 17, 1897.

I Application filed November 5, 1896. Serial No. 611,159. (No model.)

-of casing.

The object of this invention is to employ a scroll-casing and inechanism to simultane ously operate the gate mechanism for both wheels.

The features of my invention will be more fully set forth in thedescription of the accompanying drawings,making a part of this specification, in which- Figure 1 is a central vertical longitudinal section of my improvement in position for use. Fig. 2 is a transverse section on line as m, Fig. 1. Fig. 3 is an enlarged sectional plan view of the chute-case and gate mechanism, as shown in Fig. 2. Fig. 4 is a sectional plan view of one of the bridge-plates. 'Fig. 5 is a plan View of Fig. 3.

A represents the bed-plate upon which the water-wheel is mounted. It is supported upon the scrollway which forms the outer casing of the wheel. E E represent cylindrical plates which form the outer walls of the duplex chute-cases. These plates are provided with end flanges b, which form the side walls of the scrollway. B represents the outer wall of the scroll way or casin g. These parts are rigidly connected together and form a bridge for supporting the water-wheel case on its bed-plate. The chute-case and waterwheel are placed at one side or at the helix of the scroll. The end flanges b approach each other near the terminal of the scrollway, as shown in Figs. 1 and 2. 'In order to strengthen the scrollway, the flanges b of plates E are provided with horizontal flanges d, which rest on the bed-plate A, making a firm strong support for the casing and wheel.

The chutes G of the register-cases are rigidly connected to the cylindrical plates a of the chute-case; and these are in turn rigidly connected to the flange of plates 'E. The register-ease 0, plates a, and plates E with their flanges h united form a bridge for the scrollway as Well as a support for the entire casing and wheel.

The registering-casing D and the plates E upon the draft-tubes upon each side of the wheels.

N represents the bridge-tree bearing. 0 represents a shaft j ournaled in the scrollcase B, upon the central portion of which-is I mounted an eccentric P. Thiseccentric operates the crank-arm Q. e

R represents a stud connected to the respective register-gates, and it is hinged to the crank-arm Q. 4* represents a recess in the chute-case into which said stud R projects and travels as it is thrown by the crank-arm Q back and forth to' rotate the register-gate D to open and close'the same. p

In Fig. 2 the gates are shown open and in Fig. 3 the gates are shown closed. Both sets of gates are operated simultaneously by the v revolution of shaft 0.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination in a water-wheel having an outside scrollcasing,ot' a duplex chutecase O, annular plates E rigidly connected to the duplex chute-case, end flanges 1) formed on the plates E and constituting a bridge for the scrollway, and a support for the waterwheel and easing, substantially as described.

2. A duplex-water-Wheel case composed of duplex chute-cases, a central hub connected at one end thereof, cylindrical plates E connected to the opposite ends of the chute-cases and constituting the inner wall of a scrollway,

end flanges b rigidly connected to the plates each other near the terminal of the scrollway,

E and forming the side Walls of the scrollway, substantially as described. 10 and the scroll-plate B rigidly connected to In testimony whereof I have hereunto set said flanges 12, substantially as described. my hand.

3. The combination of a duplex chute-case EDW'IN R. STILWELL. with the scroll-easing formed of the plates E, Vitnesses: flanges Z) and scroll-plate B, connected to- \V. R. WOOD, g'ether, said flanges I; being inclined toward OLIVER B. KAISER.
