WATER- MOTOR.

SPECIFICATION forming part of Letters Patent No. 743,055, dated November 3, 1903.

Application filed May 9, 1902.

To all whom it may concern.-

Be it known that I, LABS ERIK BOQVIST, a subject of the King of Sweden and Norway, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Water-Motors, of which the following is a specification;

My invention relates to improvements in water-motors which are operated by the action of water under pressure brought to bear upon suitable rotary power-wheels, and has special reference to improvements in motors of this class on which Letters Patent were issued to me November 5, 1901, Serial No. 685,967.

Among numerous objects attained by this invention and readily understood from the following specification and accompanying drawings, included as a part thereof, is the production of simplified andeflicient mech; anism whereby nearly the entire force of the water can be utilized as power and preferred forms and combinations of parts incidentally developed in accomplishing the objects.

The above-mentioned and numerous other objects equally as desirable are attained by the construction, combinations, and arrangements of parts as disclosed on the drawings, set forth in the following specification, and succinctly pointed out in the appended claims.

With reference to the drawings filed herewith and bearing similar reference characters for corresponding parts throughout, Figure 1 is a horizontal section showing one-half of each of the wheels and the directrix of the machine, taken on line 1 1 of Fig. 2, viewed as the arrows indicate. Fig. 2 is a side e1evation of the motor with the spindle and relative parts in vertical longitudinal section.

Fig. 3 is a verticallongitudinal section, on

large scale, of the upper end portion of the spindle. Fig. 4. is a plan view, on large scale, of the spider-valve adapted to regulate the volume of Water discharged through the passage-ways of the directrix; and Fig. 5 is a horizontal section of the center portion of the inner wheel and directrix, taken on line 1 1 of Fig. 2, viewed as the arrows fly and produced on large scale. s s

The reference character indicates a frame of any construction suitable to properly Serial rt. 106,626. (No model.)

' support the several parts of the motor and is formed with a casing 11, in which the powerwheels 12 and 14 are arranged to rotate, and [this casing is provided with a downwardly and inwardly tapering discharge 15 at the ilower end through the dead-water escapes.

16 is an intake-pipe adapted to deliver Water under pressure to a centrally-located intakepassage of a suitable directrix 17, which lis conveniently held from rotation. This dil rectrixis formed with curved passage-ways 18, arranged to deliver said fluid tangentially to passage-ways 19 of the inner wheel, which passages are formed at a reverse curve to said i passage ways 18 of the directrix and are 1. adapted to direct the water for final discharge [against the face of suitable buckets 20, carried by the outer wheel 12, whereby the inner and outer wheels are made to rotate in oppo- Esite directions. The buckets 20 are prefer- ;ably adjustably mounted on the rim of the outer wheel by vertically-disposed stems 21, seated in suitable sockets formed in the rim and normally secured by clamping-nuts 22, having screw-threaded connection at the end of these stems or pivots, so that they may be.

rotated to adjust the buckets to a nicety relatively to the line of discharge from the pas- I sage-ways of the inner wheel, andat the discharge ends of these passage-ways suitable nozzles 23 are fixed to concentrate the fluid as it discharges.

Intermediate theintake ends of passageways 19 and the discharge ends of passageways 18 a series of breakers 25 are provided and serve to destroy the symmetry of the streams passing from the ways 18, and thus facilitate the passage of the water to the outer ways 19 and. at the same time ofier a continuous impact-surface for the water discharging from the direbtrix, which is thus made to accelerate the speed of the wheel. These breakers comprise concavoconvex plates, which are secured to the inner wheel and disposed in a circle with their concave surfaces at'right angles to the lines of discharge from the directrix and arranged in such multiplicit-y that they overlap each other in close proximity throughout the entire circle as permitted by forming them concave convex, and thus offer impact-surfaces for the water ,to constantly play upon.

The wheels 12 and 14 are mounted on re which motion is transmitted through pinions 27 and 28, gear-wheels 29 and 30, shafts 31 and 32, and miter-gears 33 and 34 to shafts 35 and 36, on which oppositely-disposed conepulleys 37 and 38 are mounted, with their peripheries in close relation, so that a suitable intermediate belt 39 serves as means to transmit power from one of the last-said shafts to the other when it is desirable to take all of move vertically.

the power from the motor by one driving-belt, using in that case either pulley 40 or 41.

In the present embodiment spindle 24 is supported in a suitable annular step-box 42, set upon a non-rotatable tubular standard 43, which rests upon the end of an adjustable bolt 44, having screw-threaded connection with the wall of intake 16, so that said box can be moved vertically by rotating said screw, and thereby adjust the spindle longitudinally, as may be desired. 7

Immediately beneath directrix 17 is a suitable seat 46, upon the upper end of which the directrix normally rests, and in this seat a spider-valve 47 is slidably fitted, so as to This valve is formed with upwardly-projecting tongues 48, which are arranged to fit the ends of respective passageways 18 of the directrix and serve to reduce the area thereof as the valve is adjusted upwardly, and thereby regulate the volume of discharge and serves to hold the directrix from rotation, while allowing it to moveupwardly by upward pressure of the water passing up the intake. As now considered this valve-seat comprises a cylindrical body of a diameter slightly less than that of the directrix, and the attendant valve is formed to fit snugly but movably therein and to also slidably embrace the standard 43, and a suitable governor 50 is adapted to adjust said valve. This governor is of any ordinary or desired form, but as now considered comprises a pair of balls suspended from a vertical shaft, so as to swing outwardly when the shaft is rotated, and this shaft is driven by a suit able belt from a pulley 50, mounted on the shaft 36. Thegovernor is operably connected to the spider-valve by a collar 51, which is slidably mounted on the shaft of the governor and operably connected to the balls thereof, an arm, as 51, connected to the collar, a lever 52, to which said arm is secured, and a valve-stem 53, which extends from said lever to the valve and is preferably located within the spindle and secured to the valve by a key 54, which is loosely received in suitable elongated slots formed in the wall of the standard 43, whereby any acceleration of speed above a given rate causes the valve to be partly of the motor.

In thepresent instance water is admitted to standard 43 from the intake through suitable ports 43' and passes upwardly to and through the bore of spindle 25, and therefrom through suitable apertures, as 26, to a water-tight chamber 55, which is formed concentric with said spindle. In this chamber a piston, as 56, is convenientlysecured to spindle 25 beneath said apertures 26 and is provided with a suitable peripheral packing ring, whereby the water admitted to said chamber is made to counteract the upward pressure of the water in the intake bearing upon the directrix, and thereby reduce friction in the upper hearing or thrust of the spindle. In the lower end wall of this chamber 55 a suitable relief-valve 57 is mounted to free the lowerend of the chamber of water leaking from the upper end thereof, and thereby maintain pressure on the upper surface of the piston 56. This valve consists of a suitable ball, which normally rests in a seat, as 58, and is operated by upward action of a horizontally-disposed lever 59, which has at one end an upwardly-projecting pin 60,adapted to lift said ball, and is operably connected at the opposite end to a piston 61, mo'vably seated in the said wall of the chamber and held against a predetermined pressure of the water by a suitable spring 63, which is of proper strength to allow said piston to be depressed by pressure of said water when the portion of the chamber below the piston 56 becomes filled, and the water is thus discharged and passes away through a suitable pipe 60'.

The upper end of the shaft 25 is loosely fitted in the lower end wall of chamber 55, so that a certain percentage of water will pass therefrom and run down the shaft, and a tubular casing, as 66, is rigidly fitted to the shaft above the sleeve 26 and formed with longitudinally-disposed passage-ways 67, arranged in the bore for the water to pass through this casin g, thence through the sleeve to the hub of wheel 12, through the bore of which it will seep, and pass outwardly between the lower face of this hub and the hub of wheel 14, thus serving to keep the bearingsurfaces of these hubs constantly lubricated. The top and bottom ends of casing 66 are received in suitable stuffing-boxes arranged on the bottom wall of chamber 55 and on the upper end of sleeve 26, and the drive-pinion 28 is keyed or otherwise securely fastened to this casing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-
