(NqModel.) Tl H. RISDON 8E Wl W. TYLEPM TUEBINE WATEE WHEEL.
16.268,287. Patented Nov. 28,1882.'
WITNESSES E QWM A N. PETERS www-magnum. wa-ningmn. DA u UNrrnD States To all whom lit muy concern:
Be it known that we, THEoDoRE H.RIsDoN and WILLIAM W. TYLER, citizens of the United States, residing in lllount Holly, Burlington county, New Jersey, have invented certain Improvements in Turbine Water- W heels, ol' which the following is a specification.
The objects of our invention are to prevent binding ofthe wheel in its casing, to obtain the maximum of power at all stages of water, and to render the wheelcasing independent of any defects in the Hume or chest ot' the draft-tube.
In the accompanying drawings, Figurel isI a longitudinal section otpart of a Hume or penstock, showing our method of constructing and mounting Water-wheels; Fig. 2, an enlarged section ofthe wheel, its casing, and gates; Fig. 3, a transverse section on the line 1 2, Fig. l; Fig. 4, a transverse section on the line 3 4, Fig. l; and Figsand 6, diagrams illustrating one ofthe features ot our invention.
A represents part of a flume or penstock; B, a horizontal shaft having two wheels, D and E, and F a draft-tube common to both wheels. The wheels D and E are, so t'ar as regards their general construction, similar to thewheel de.- scrihed in our Patent- No. 193,283, dated July MW?, c being a guide-rim, and b a crownplate supported by goose-necks d, which serve as guides for the gatesj", the latter being connected to a sleeve which is guided on the tubular projection g of the crownplate andin a box IL at the end bt' the same, and is operated by means of a rack and pinion, se as to open or close the gates simultaneously. The guiderimand crow n-plate thus form practically, with the gates, the casing of the wheel; and one 'of the features of our invention consists in proriding the wheel with a vertical bearing only `against the guide-rim and crown-plate. Thus, as will be observed on reference to Fig. 2, the wheel has a vertical bearing against the crownplate at x and a vertical bearing against the guide-rim at 1/, and these are the only points of contact between the wheel and casing. V By this means slight vertical displacement of the wheel in the casing, due to wear or sagging ot' the shaft D, does not cause the wheel to bind,
nor does it interfere with the free ruiming of the wheel. Thismode of constructing the wheel also permits'. us to control the shaft-bearings PATENT OFFICE.
THEODORE H. RISDON AND VILLIAM YV. TYLER, OF MOUNT HOLLY, N. J.
TURBINE WATER-WHEEL.
SPECIFICATION forming part of Letters Patent No. 268,287, dated November 28, 1882.
Application filed July 24,1852. (No model.)
by set-screws, so that said bearings can be set up to compensate for wear, and keep the shaft properly lined. (See Fig. 4.)
The casings of the wheels are supported by frames G G, connected to the guide-rim and to the box hot' the crown-plate, so that said wheelcusings are entirely independent of the sides of the liurne and ot' the drafttube chest. By this means the said chest and the sides of the iiume may be made of sheet-iron or wood and comparatively light, as there can be no distortion ot' the wheel-casings and binding of the wheels in the event of the chest or side ofthe flume yielding to the pressure of the water.
It will he seen on reference to Fig. l that the capacity of the wheel E is greater than that ot' the wheel D-that is to say, the former wheel has a greater area ot discharge, and is consequently more powerful than the otherboth wheels, however, running at the same speed, owing to the fact that they are ot' the same diameter at the gate. The object of this arrangement is to obtain the maximum effect ofthe waterat all stages of water by working as near full gate as possible. For instance, when the water is high both wheels may be run at full gate, and as the supply diminishes the gates may be gradually closed until economy suggests the shutting off ot the small Wheel andthe ruiming of the large wheel at full gate. It' further restriction becomes necessary, the gate oft-he large wheel may be gradually closed until it reaches a point where it becomes economical to run the small wheel at full gate, and the gate of the small wheel may then be adjusted as circumstances suggest until it is necessary to shut down altogether. In order, however, to obtain the full effect of this arrangement-that is to say, to obtain any desired amount of power between the maximum ot' both wheels and the minimum of the small wheel-itbecomes necessary to so constructlhe wheels that they will give a high percentage of power in working from full to about threequarters or halll gate; and with this end in view we construct the gates of the wheels so that they will present a smooth regular surface instead ot a sharp edge to feed and direct the current of water upon the wheel at part gate.
In the drawings we have shown a ange or garniture upon the edge ofthe gate as a means IOC lin the area of the buckets or water-passages.
of accomplishing this result; but the same end may be attained by other means-as, for instance, with a gate of a form similar to that shown in Fig. 7.
In the wheels shown in Fig. 1 the difference in capacity is due to a difference throughout Variations in the capacity of the wheel may be effected, however, by simply varying the area of discharge, the form ofthe inlets remaining practically the same. Thus in Figs. 5 and G we have shown two Wheels having the same inlet form; but the wheel D basa discharge in line with the shaft only, while the wheel E has, in addition to this, a circumferential discharge, due to the flaring of the rim of the wheel. The same circumferential discharge might be effected by cutting away the wheel at and near the discharge ends of the buckets, and the discharge may be inward or toward the shaft, it' desired, instead of outward or away from the shaft.
Although we have shown a continuons horizontal shaft, B, carrying both wheels, it will be evident that two shafts coupled together between the wheels are the equivalent of-the single continuous shaft; and where we have alluded or may allude tothe shaft77 we wish to he understood as meaning eithera continuous or a coupled shaft.
We claim as our inventionl. The combination 0f the crown-plate, guide-rim, and gates with the wheel carried l by a horizontal shaft and having vertical bearings m yagainstthe said crown-plate and guideriin, as set forth.
2. The combination of the crown plate, guide-rim, and gates, the wheel having vertical bearings y against the crown-plate and guide-rim, and the horizontal shaft B, adapted to adjustable bearings, as set forth. y
3. The combination of the horizontal wheel, the fiume, the draft-tube chest, the crown-plate, and guide-rim, and a structure, Gr, whereby said crown-plate and guide-rim are supported independently of the said chest on thesides of the Hume, as set forth.
L1. The combination ofa horizontal shaftwith two wheels of dilfereut capacities having gates which present a smooth regular surface to feed and direct the water upon the wheel at part gate, as set forth.
5. The com bination ofahorizontal shaft with two water-wheels, one constructed with a longitudinal discharge only and the other having both a longitudinal and a lateral discharge, as set forth.
In testimonywhereof we have signed our names to this specification in the presence of two subscribing witnesses.
