BRUNT, OF SAME PLACE.
IMPROVEMENT IN TURBINE WATER-WHEELS.
Specification forming part oi Letters Patent No. 136,784, dated March 11, 1873.
To all whom it may concern:
Be it known that I, STEPHEN M. STEVENS, of Lancaster, in the county of Keokuk and State of Iowa, have invented certain Improvements on Turbine Water-Wheels, of which the following is a specification:
The drawing hereof shows a turbine wheel constructed under my invention, Figure 1 being a top view of the wheel; Fig. 2, a sectional view with part of the frame omitted; Fig. 3, a view of one of the gates; and Fig. 4, a view of one of the buckets.
a indicates the base of the wheel, with a cross-bar, I), to support the step c; d, the inclosingcase; e, the buckets; f, the band to which the bottom of the buckets is affixed; g, the plate, to which are attached the upper ends of the buckets; h, the shaft; 1', the supporting cross-bar for the shaft; j, the topplate; 70, the chutes or water-inlets l, the gates; m, the bar for moving the gates.
The buckets, gates, and several of the other parts are made of steel. The buckets are secured to the plate and band by lugs, which are formed by clipping the sheet-steel of the buckets and bending them to the proper shape. The band f forms the entire support for the lower ends of the buckets, thus completing the periphery of the wheel.
The gates lie in agroove formed in the top plate, and are, therefore, very fully protected from displacement and injury. They are made of steel, and have an inclined and a beveled edge at the end near the chute. This cutting end of the gate serves to keep the chute-mouth clear of wood, sticks, &c., and to remove any ice that may form about the opening. The form of the gate here shown and its being fitted into the groove in the top or deck plate insure its being always tight and not leaking, as the gate will always fit close to the seat.
The means for opera-ting the gates, which are shown by Fig. 1, the pinion fitting into Witnesses:
