TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 651,731, dated .Iiine i2, 19oo;

Application filed September 24, 1898. Serial No. 691 ,809. (N0 model.)

To all whom it may concern.-

Be it known that 1, JOHN 1V. TAYLOR, a citi-.

zen of the United States, and a resident'of York, in the county of York and State of Pennsylvania, have made certain newand useful The object of my invention is to improve the construction of that class of turbines which receive the water upon the upper part of the buckets through stationary guides or chutes surrounding the wheel proper, the admission of water being controlled by means of an annular or cylindrical gate, which is adjustable in such manner as to open or close the water inlets or chutes at the top.

The several features of construction, an ran gement,and combination of parts embodying my invention are hereinafter set forth, and illustrated in the accompanying drawings, (two sheets,) in which- Figure 1 is a side elevation of my improved wheel, the gate being shown lowered, as required for free admission of water.

proper. Fig. 3 isahorizontal section on line 3 3, Fig. 2. Fig. 4is a horizontal section on the line 4 4, Fig. 2. Fig. 5 is a plan view of the cylindrical gate. Fig. 6 is a side view of the wheel proper or runner.

The parts comprising the wheelcasing are indicated by lower-case letters, and the movable parts are indicated by numerals, for convenience of distinction. The upper portion of the wheel-casing comprises the horizontal top or cover a, the guide or chute frame b,

tal flange of the base-ring d, which rests upon the floor of the flume, as indicated by dotted lines in Fig. 1, and is suitably bolted thereto. The upper portion of the central draft-tube c seeFig. 2) is rabbeted or grooved to adapt Fig.2. is a central vertical section of the wheelit to receive the base of the guide-frame b, which is bolted thereto. Vithin the lower or flaring draft-tube 'e is arranged a horizontal skeleton frame or spideI""f,which is bolted to the sides of said tube, as shown in Fig. 2. Said spider is provided centrally with a polygonal socket adapted to receive the corresponding shank of a removable stepblock 1, whose upper end is conical and fits in a corresponding recess in the rotary shoe 2, in which the wheel-shaft 3 is stepped. The lower end of said shaft is polygonal and fits in a corresponding socket in the aforesaid shoe 2. The shaft is guidedand adapted for adjustment in vertical position by means of blocks 4: and set-screws 5, connected with the box ,forming an attachment of the top aof the wheel-casing. A packing 6, composed of fibrous material or leather,is arranged around the shaft 3 in the upper portion of said box g for the purpose of preventing influx of air to the runner of the turbine. Said runner7 is provided with a tapered hub S, which is suitably keyed upon the shaft 3. Surrounding the lower portion of the buckets 9 is a thick band 10, whose upper edge is rounded or beveled, as shown in Fig. 2, and worksin frictional contact with a correspondingly-beveled flange h, that projects inwardly from the top of the central draft-tube c and is constructed integrally therewith. By this means the escape of water between the buckets and the lower edge of the guide-frame and topof the dra f t-tube is avoided, and the whole power or force of the water-current is therefore expended upon the buckets.

My improved gate 12, by which the influx of water to the wheel proper is controlled, is made cylindrical in form and adapted to surround the guide-frame b and central drafttube a, as shown. Said gate is provided-at its lower edge interiorly with an inwardlyprojec'ting flange 13, which works in sliding contact with the draft-tube c. The upper 5 edge of the latter is also provided with a corresponding flange t, which extends outwardly 'and works in sliding contact with the inner side of the gate 12. The upper edge of the gate has also an inwardly-projecting flange mo 15, which works in contact with the edges ofthe bars composing the circular chute-box b.

By this arrangement close joints. are formed, friction is reduced-to a minimum, and the upper flange cuts or shears 0E Weeds, plantrstalks, and other trash that may lodge the joint formed by the adjacent or meeting edges. of such-semicircularparts, and, being bolted to the latter, they connect them so that they form a rigid cylinder.

against the chute-bars. A series of lips or flanges 16 is bolted to and projects from the. r gate-"between the chute-bars; butthis feature is unimportant;

It will be seen that my improved gate is adapted to open downward and close upward, so that water is admitted at the top of-the wheel proper, and thereby produces the greatest efiect practicablebefore being discharged,

from the Wheel into the draft=tube c. I propose to employ any suitable means for raising and lowering the gate; but in this instancel'showrods 17 for this .purpose, the: same being connected to. rack-bars 18, whose, teeth-meshwith pinions 19 uponatransverse: shafitrfzflt r- Rotation isiimparted to saidshaft by meansliof beveled gearing 21,, operated from any-suitable source of power; I coun terbala'nce the gate and the :rods and rack- .rconnected therewith by means of a weight 22,;
