ELASTIC-FLUID TURBINE.

Patented Au. 13, 1912.

Original application filed July 7, 1910, Serial No. 570,879. Divided and thisapplication filed January 23,

1911. Serial No. 604,086.

To all whom iamay concern Be it known that I, \Vrwono DARE, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented new and,

engine to which my invention is applied,

taken on the axial plane of the engines rotor, certain parts being broken away; Fig.

2 is a sectional view of certain parts taken ..on line ss of Fig. 1; Fig. 3 is a transverse section of certain parts shown in Fig. 2 and taken on line az-zv thereof, and Fig. t is an under plan view of the rotor shaft and parts of the governor connected therewith.

A frame or casing 1 incloscs the operative parts of the turbine engine to which my present invention is applied. The screw plug 2 may be removed to supply oil. The rotor shaft 3 carries the rotor body 4 provided with buckets The elastic fluid (hereinafter referred to as steam) is conducted from its supply by a suitable passage, as the circular passage (3 in the casing, through an annular opening 7 and a passage 8 into the recess 5) formed in theinner face of the retaining nut 10. The steam then passes through the strainer 11, and through the'passage 13 therein, whose lower extremity forms the seat of the valve it; it is thence discharged by suitable alining passages 15, as shown, into the rotor buckets 5. The steam may also be supplied through the opening 45.

A governor to control the valve 14 and regulate the supply of steam to the buckets, comprises and. operated by the following parts: when the centrifugal force becomes sullicient to overcome the spring 18, governor bell-crank levers 1S.) pivoted at 20 on the rotor body move the sleeve 21 along the rotor.

shaft 3 (which said sleeve encircles) and,

the end of such sleeve being joined to the thrust collar '22 (bearing on the carbon washer 23 held in the non-rotating collar 24), moves said collar 24 axially-the rotor shaft. This movement throws the lever 25,

fulcrumed at 26 and pivoted at 27 to the 001- lar 21, which movement, through the antii'riction roller 28, operates the lever 29'ful- "crumed at 30, and thus closes the valve 14 against the pressure of its spring 31 surrounding the valve stem 32, by hearing v against the adjusting nut 33, which may be locked in proper adjustment by the jam nut 34. The pressure of the spring 18, one end of which is fastened to the sleeve 21 and the other to theeollar 43, is adjusted by screws 35 threaded in such collar and journaled 0n the rotor body, such screws being held from accidental turning by their fiat sided heads being held in engaging recesses 36 in the face of the rotor body. are turned to adjust. the pressure of spring 18, their fiat sided heads are forced, by so turning the screws, to mount the inclined sides (shown in Fig. 4:) of the recesses 36 at each half turn; the pressure of the spring 18 tending to keep the heads in the recesses and the turning of the screws raising the heads out of such recesses.

The support or cage 37 of the valve 14: is formed of separate piece from the casing or 5 frame of the engine, is conical in shape, shown, and is adapted totightly fit in a correspondingrecess in such casing, in which it is securely held as by the retaining nut 10,

but may be readily removed to'eflect repairs,

cleaning, etc.- A passage 38 leads from passage 8 to the rear of the valve 14 for the purpose of adn'iitting steam to balance the pressure of the steam on the face of the valve; the area of the cross-section of the passage 13 and of the cross-section of the annular chamber 46 1s, in order to efiect a perfect balance, equal. The internal rib 39 in thc'casing serves to confine lubricatihg oil, as shown in the oil chamber 40; the

vapors in the casing chamber, stirred by the motion of the running parts of the engine, take up this oil and thus the governor, etc., are constantly luln'icated. The screw plug 41 closes an opening in the casing through which the screws may be adjusted, and

iVhen the screws 35 7 5 the screw plug 42 may be removed to supply -oil to the chamber 40. 'The exhaust pipe is shown at 4A.

This application is division 3 of my original application Serial No.57 0,87 9, filed July 7, 1910.

My invention may be embodied in varying mechanisms and may be. applied to other ypes ofelastic fluid engines, and I do not propose to confine myself to the construction shown and described.

I claim- 1. In a machine of the character described, a valve ca e having a lifting valve and valve-seat therefor, '21 fluid supply passage controlled by the valve, and a fluid passage leading from'the fluid supply to the inner side of the valve opposite the valve-seat, to balancelor counteract the pressure of the fluid on the face of the valve.

2.. In a machine of the character described, a valve support having a lifting valve and a seat therefor and a fluid supply assage leading to the valve seat and contro led by the valve, said support having also a fluid passage leading from the source of fluid supply to the inner side of the valve opposite the valve seat, the area of so much of the face of the valve as is pressed by the fluid supplied bythe first-mentioned passage in the closed position of the valve being equal to the area of the rear of the valve pressed by the'fluid supplied by the second mentioned passage.

3. In a machine of the character described, a conical and removable valve cage having a fluid strainer with. a fluid passage and radially extending straining passages c0m municating therewith.

t. In a machine of the character described having a casing frame and a rotatable shaft and a valve for controlling its rotaryspeed, a governor for said valve comprisin a governor lever centrifugally controlle a second lever fulcrumed on the casing frame, means intermediate the governor lever and the second lever to actuate the latter by the former, and a third lever operating toclose the valve and actuated by the second lever, said levers and actuating means being cont,ained in the casing frame.

-5. In a machine of the character described having a frame and a rotatable shaft and' a valve having a valve stem, for controlling its rotary speed, said valve and stem having a longitudinal reciprocal movement, a governor for said valve comprising a governor lever centrifugally controlled, a sleeve encircling the shaft and slidable thereon by the governor lever, a second lever fulcrumed on the frame and having a collar pivoted thereto and adapted to be moved longitudinally the shaft by said sliding movement of the sleeve, and a third lever operating the valve stem to close the valve and actuated by the secondlever.

6. In a machine of the character described having a frame and a rotatable shaft and a slidable thereon by the overnor lever and.

adapted to move the co lar, and a spring pressing against said movement and whose tension is adjustable by screws carried by the rotor and threaded in a collar carrying the spring.

.7. In a machine of the character described, having a rotatable shaft and a rotor carried thereby and a valve for controlling its rotary speed and a governor for said valve comprising a governor lever centrifugally controlled and connections intermediate the governor lever and the valve to operate the latter by the 'movement of the former, a spring pressing against said movement whose tension is adjustable by screws carried by the rotor and threaded in a collar carrying the spring, and whose heads are held in engaging depressionsagainst accidental movement.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
