WALTER DUKE SMITHEY, QF BAY CITY, TEXAS.

Application filed August 22, 1917.

To all whom it may concern:

Be it known that I, l VALTER D. SMrrHEY, a citizen ofthe United States of America, residing at Bay City, in the county of Ma tagorda and State of Texas, have invented certain new and useful Improvements in Turbine-Motors, of which the following is a specification.

This invention relates to turbine motors, and means for controlling same.

The object of the invention is to provide a simple and economical motor which'can be efiectively operated by motive fluid.

A further object of the invention is to provide'improved means for governing the speed of the turbine motor.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described, and particularly pointed out in the claims.

In the drawings:

Figure 1 is a perspective view of my improved motor,

Fig.2 is a central vertical section,

Fig. 3 is'a detail view of the resilient duct,

. Fig. 4: is a transverse section of the motor.

1 indicates a motor casing formed with an inlet port 2, and an outlet port 3 the latter communicating with a muffler 3 Between the inlet port 2 and outlet port 3, is bolted at 4, a resilient element having an inlet duct 5, which is formed'at its exit end with a V concave shield 6. Secured to a driving shaft 7, within. the casing 1 is a rotor 8, formed on its periphery with a plurality of pockets 9. The shield 6 snugly fits the periphery of the rotor and forms a tight joint to prevent the motive fiuid leaking from the pockets.

The rotor travels in oil contained in the casing, and the bottom of the latter is formed by a detachable plate 11, which inclines downwardly toward the rotor to form a well directly under the latter.

The casing 1 is provided with a hollow extension 12, which communicates with'the inlet port 2. 13 indicates a valve seat formed in the extension 12, to one side of the inlet port 2, and cooperating with this seat is a valve 14, the stem 15 of which extends up through the top of the extension, and is providedwith an adjustable nut 16.

The driving shaft 7, extends through an opening 17, in one side of the casing 1, and which communicates with a chamber 18,

formed by an auxiliary casing 19, bolted or otherwise fastened to one side of said casing. Bolted to the auxiliary casing 19, is a cap plate 20, in which is formed a central bearing 21, for one end of the driving shaft 7, and between the end of the latter and the cap plate is interposed a strong cup shapethrust spring 22. This thrust spring forces the shaft 7 laterally which retains a flanged washer 23, snugly against the bearing 24, in the opposite side of the casing.v

The auxiliary casing contains oil to lubricate the parts to be described, and the thrust spring and washer serve as'a means for preventing the oil leaking around the bearing.

Slidably mounted on the shaft 7 by a key and slot connection 25, is a cone 26, located in the opening 17, and provided with cars 27, to which links 28 are pivoted. The 0pposite ends of the links are pivoted to weights 29, which in turn are pivoted to ears 30, on a collar 31, fixed to the shaft 7.

32, indicates a vertical slidable lever mounted in a guidein the casing 1, and pivoted at its upper end to a controlling lever 33, formed with an opening 34:, in which loosely fits the nut 16 on the valve stem 15. Pivoted to a standard on the extension of the casing is a handle 35, the foot end 36.

thereof. engaging under the free end of the controlling lever 33, as shown. A spring 36", is attached to the controlling lever 33 A. coupling 41-1, is screwed to the outer end of the extension of the casing, and in this coupling is mounted a pressure regulating valve.

In operation the handle 35, is released, which causes the spring 36, to open the valve 14, and the motive fluid passes through the inlet port 2, inlet duct 5, to the pockets on the periphery of the rotor. The shield 6, acts as a packing, consequently the full effective force of the motive fluid acts on the pockets to rotate the rotor.

As the rotor travels at a rapid rate in a bath of oil, it follows that the bearings, be tween the shieldand the peripheral surface of the rotor, and the shaft bearings will be thoroughly lubricated.

; As helsp edi flthe rotor increase b yo d 1 that set by thetension of the spring 36, the

weights 28, are centrifugally' thrown out- 7 wardly which slides. thelcone 25, on theshait 7, and elevates the vertical lever 32, which raises the controlling lever 33 against the. tension of the spring 36, and correspond ingl-y raises-the valve El i, to itsseat' l3, and

shuts off thesupply of motive fluid. lmmee diately thespeed-of the rotordecreases, the spring 36, acts to restore the lever valve, and theweights act to restore thecone. 5
