IMPROVEMENT IN WAT ER-WHEELS.

Specification forming part of Letters Patent No. 192,671, dated July 3, 1877; application filed May 8, 1877.

To all whom it may concern:

Be it known that I, JAMES J. BoURGEoIs,

. do hereby declare that the following is a full,

clear, and exact description of the same.

My present invention relates to an improvement upon that for which I received Letters Patent of the United States, No. 171,088, dated December 14, 1875.

In the former invention, horizontally-sliding gates are arranged over the wheel to regulate and out off the flow of water to the wheel. When there is a full head of water, the vertical pressure on the gates causes so much friction that it is difficult to operate them. To avoid this result I have devised a two-part hinged gate, and arranged it beneath the wheel, together with a shaft and chains for operating it, as hereinafter fullydescribed.

In the accompanying drawing, forming part of this specification, Figure 1 is a sectional elevation of a wheel-casing and gate, the latter being shown closed by full lines, and open by dotted lines. Fig. 2 is a cross-section of the wheel-casin g on line :10 a, Fig. 1, representing the gate open. Fig. 3 represents a modification.

In the several figures, A indicates the easing or part of the flume in which the turbine wheel B is placed. 0 is a rotating shaft, arranged horizontally beneath the wheel, and having its hearings in the casing A. This shaft is provided with pulleys or chain-wheels a a, on which are wound the chains 1;, for raising and lowering the hinged parts of the gate.

In Figs. 1 and 2 the gate is shown formed of two semicircular parts, D, hinged on a central rod, 01. A gate of this construction is most suitable for use where there is little fall, the hinged parts D opening downward in a holein the bed of the stream, in order to give as much fall as possible.

In Fig. 3 I show a modification best adapted for heavy streams with a good fall, the parts D of the gate being attached to separate parallel rods d, their inner ends overlapping, and their outer ends resting on shoulders or brackets attached to the inner side of the casing.

In this case said parts D fold upward, when opening, to allow the discharge of water from the wheel. I

' My improved construction and arrangement of gate enables it to-be easily operated for closing the discharge-opening of the wheel, or regulating the flow of water for increasing or diminishing the rapidity of rotation of the wheel.

What I claim is- The gate made in two semicircular parts, D, hinged on a rod or rods beneath the wheel B, the shaft 0, having pulleys a, attached, and the chains 1), all constructed as shown and described.
