WATER- SPECIFICATION forming part of Letters Patent No. 716,650, dated December 23, 1902.

Application filed January l5, 1902l Serial No. 89,896- (No model.)

'.lb LEZ whom, it nerr-y concern:

Be it known that we, MILD L. G. WVHEELER and DANIEL D. BESSE, citizens of the United States, residing at Seattle, in the county of King and State ofWashingtou, have invented certain new and useful Improvements in Water-Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to Water-motors. Its object is generally to utilize in a simple manner the power of water passing through pipes under pressure and to provide compensating devices whereby the power-shaft shall be rotated at a uniform speed.

More particularly, the invention is intended for use where it is advantageous to utilize all available water for a specific purpose, as in hydraulic mining, and where at the same time auxiliary power is essential-for generating electricity for lighting and other purposes, which we provide directly from the water in transit by switching the same, so to speak, through a by-pass upon the main pipe-line,

turning in an unbroken state to the main line the entire quantity of water.

The invention 4is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure l is a plan viewv of a motor constructed accordingto our invention, the cover :n of the casing being removed. Fig. 2 is a substantially central vertical longitudinal section of the same, and Fig. 3 is a cross-section through line 3 3 of Fig. l.

In the said drawings the letter n indicates a cylindrical casing or pipe terminating in bends b, which are secured to a water-main v in a proper manner, so as to make watertight joints therebetween. Positioned between the said openin gs of the main is a gatevalve c. by-pass through which all or a portion of the water may be directed. Extending through the said casing is an axial shaft d, provided with a continuous helical `flange or iianges d', integral therewith, of one or more convolutions. An extended hub or hollow shaft e,

mounted upon the aforesaid shaft, also has a continuous helicaliange e', but of opposite hand-that is, if the flange d' upon the firstabstractiug the said power therefrom, and rei Consequently the-casing o forms a' mentioned shaft is a right-hand thread the other, e', will be aloft-hand one, or vice versa, and in consequence are rotated in opposite directions by the water passing therethrough. Oppositely-arranged bevel gear-wheelsf and f', ixedly secured to shafts d ande, respectively, rotate a counter-shaft g through gearwheel g. Stuffing-boxes h and h' are provided where the driving-shafts d and e project through the casing and also upon the outer extremity of the hollow shaft e. The gland i of the latter box h' and a bushing i at the inner end of shaft e form bearings for the same, the intermediate distance being preferably bored to form a loose fit upon the internal shaft, minimizing the friction therebetween. A rotary cut-off valve 7c, having a plurality of radial apertures lo', which register with corresponding apertures in a seat Z, is actuated by a governor m, controlled by pulleys m' and belt fm" from shaft d, regulating the iniiow ofthe water, and consequently the speed of the motor.

gages with the lifting-rod n of the governor. Gate-valves o are positioned in the ducts connecting the motor-casing with the main.

p p' are drain-cocks.

q is an air-vent.

fr indicates the main bearings.

A compensating screw s, passing through a threaded bracket t of the frame, and a collar u, rigidly secured to the shaft ,are provided to take up the thrust of the main shafts.

Having thus described our invention,'what we claim as new, and desire to secure by Letters Patent, is-

In a water-motor, the combination with the water-main, of a oy-pass having its inlet and outlet communicating with the main, a horizontally disposed drive shaft extending through the by-pass, bearings r extending outwardly from the ends of the by-pass for supporting said shaft, a helical iange integral with the drive shaft, a hollow shaft mounted on said drive-shaft, a bushing at the inner end of the hollow shaft, said hollow shaft terminating adjacent the inner end of the helical iiange of the drive-shaft, said bushing forming a bearing for the hollow shaft, a helical flange of opposite pitch to the iiange of the drive-shaft formed integral with n is an arm secured io the said valve, which en- IOO hollow shaft and the drive-shaft, with a comf mon gear meshing with said gears of the holloW and drive shaft, substantially as described.

In testimony whereof We affix our signatures in presence of two witnesses.
