IMPROVEMENT lN ROTARY HYDRAULIC ENGINES.

Specification forming part of Letters Patent No. 196,266, dated October 16, 1877; application filed June 8, 1877.

To all whom it may concern Be it knomi that I, JAMES TALLEY, Jr, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Turbine Wheels, of which the following is a full and clear description.

This invention relates to certain improve- I ments in the wheel itself, the casing which incloses the wheel, the chute for delivering the water to thewheel, and in the discharge arrangements for conducting the water from the wheel.

The invention consists in constructing the wheel with sloping buckets on its periphery, which said buckets are terminated against flanges at each side of the wheel, the flanges being scalloped out between the buckets, so as to allow the spent water to escape on the eXit side of the wheel, and with annular packing-rims formed on each side of the wheel, so as to confine the water-way to the periphery or near the periphery of the wheel. The casin g which incloses the wheel is constructed so that the wheel may be run in either a vertical or horizontal position, and the eduction-ports are formed so as to be changed at will to Suit either position.

The chute which delivers the water to the wheel is formed with its discharge-aperture in a wave -line, extending for some distance around the periphery of the wheel, and diminishing from the first point of inlet toward the last end, so as to deliver the volume of water onto one or several buckets simultaneously, and with increasing force, decreasing the volume in proportion to the increase of distance from the inlet-pipe.

The invention will be readily understood by reference to the accompanying drawings, of which-- Figure 1 isa sectional elex'ation of the improved turbine wheel, its casing, and inlet and outlet pipes, taken as the machine would appear when used in a vertical position. Fig. 2 is a transverse sectional elevation. of the same taken in the same position as above. Fi 3 is a side elevation of the wheel taken without the case. Fig. 4 is a cross-section of the wheel taken without the case. Fig. 5 is a plan of that side of the case which becomes the bottom when the machine is used in a horizontal position. Fig. 6 is a plair of the wave-line chute-aperture. Fig.7 isa detached plan view of-one-half of the case.

The housing or case A may be formed with its exterior cylindrical or any other approved shape; but the interior chamber A will be made either elliptical or nearly so, as shown in Fig. 1. 5

The interior faces of the ends A A of the said case will be flat, so as to fit tightly to the flat ends of the part A, to which they are to be securely bolted; but the exterior faces of the ends will be spheroid, as shown in Fig. 2, so as to accommodate in the part A, which forms the bottom when the machine is used horizontally, the eduction chute. This spheroidal form of the ends also gives the requisite amoimt of strength to these plates without an unnecessary amount of metal.

The wheel B is, of course, circular in form, as is shown clearly in Fig. 3, and it is mounted on the drivingshaft O, which finds its bearings c c in the end plates A A of the case.

When the machine is used in a horizontal position the lower end of the shaft 0 rests on a step, 0, which is adjusted as to height by means of the set-screw c From the driving-shaft O, of course, power may be communicated in the usual manner. The extreme periphery of. the wheel B terminates in two flanges, b, between which are placed the buckets -or wings I). These buckets are set sloping at an angle of about thirty degrees (more or less) with the radial lines of the wheel. Between each pair of the said buckets the flanges b are cut out in scallops I), as shown best in Figs. 1 and 3.

Just inside of the scallops I), on the outside ofthe wheel B, are formed annularfianges B, which form packingrims to bear against the inner faces of the casing ends A A raised seats a on the said inner faces of the ends being provided on the working side of the wheel to bear against the said flanges.

The effect of this construction is to cheapen the cost, by reducing to a miniminn the bearing or finished parts, and also to reduce to a minimum of friction between the wheel and the case, the amount and also tolimit the working water to contact with the wheel at or near its periphery.

The wheel 13 is placed eccentrically in the 'zehamber A so as to touch,or nearlytouch,

the case on: the inlet side, and leave alarge .water way on the outlet side, as shown in -Fig.'1

V the wheel B and the oaseA' on the outletside, r asabove explained, thedistance between the wheel and the case graduallydecreases toward the minimum distance at the first part'of the inletaperture.

The distance between the points 11 and: d

sex 'eral of the buckets of the, wheeh ide quarter of the periphery of the wheel, more ater; will be distributed better over the widths in harmony with its force.

The gradually-increasing space between the wheel 13 and its surrounding casing A, between the point (I and the opposite outlet E, as hereinbefore described, will accommodate the in crease of the flow of water from the chute between the points 01 and d; There are two outlets, 1*] and F, for the escape of the spent water from the case AA A The first of these, E, is used to discharge the water from the periphery of the casing A at the bottom, when the machine is used in avertical position, and the other outlet, F, is formed on the side A which becomes the bottom when the machine is used in a horizontal position. A screw-cap, G, is mutually interchangeable to screw upon in use. A slide or gate, a is formed and seated in, the casing A, so as to close the inner end 1 a I :of the outlet Ewhennot in use, so as not to with the other outlet. II
