Specification of Letters Patent.

Patented July 23, 1912.

To all whom it may concern.

Be it known that we, lVILLIAM A. Soorr a-nd'HnNnY P. GRANT, citizens of the United States, residing at Tacoma and Seattle,: re-

spectively,'in the counties of Pierce and King, respectively, State of lVashington, have invented certain new and useful Improvements in Turbine-l lngines; and we do hereby declare the following to be a full, clear, and exact description of th invention, such as will enable others skilled in the ,art to which it appertains to make and use the same. reference loc g had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in turbine engines adapted for use with a fluid, either' gas, steam or water, and affords means whereby the highest possible economy may be obtained and affords means whereby a maximum power may be obtained by a minimum of energy.

()ur invention comprises Various details of construction andcombinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claim.

\Ve illustrate our invention in vthe accompanying drawings, in which :-Figure 1 is a vertical central sectional YlGW through our improved rotor and transversely through the shaft, and Fig. 2 is a vertical sectional View taken in a plane at right angles to the section in Fig. l. v

Reference now being had to the details of the drawings by letter. A designates a casing in which a shaft l) is mounted in suitable hearings and lixed to said shaft, by means of the spider arms is a tubular shell D having circuinern tial ports E formed therein through hich the fluid passes from a series of spiral ducts or passageways F. The interior of said shell is provided with exhaust ports H leading to the exhaust passageway K. Said spiral ducts or passageways are separated from one another by means of the thin partitions O, the circumferences of which partitions form a series of separate compartments through which the fluid is directed from the inlet N.

In operation, in our improved turbine the shell with the series of spiral passageways form'ing a rotor affords means whereby the fluid, as it enters theduct N, will be forced to take a uniform spiral course of a length corresponding to the length of the spiral turns of the rotorx By this means an exceedingly heavy torque will be produced from the moment that the fluid enters the spiral passageways. In the action of the fluid, either steam, gas or water which may be utilized for carrying the energy, the

properties of adhesion and velocity are depended upon, the attraction of the fluid to the rotor surfaces and the resistance of these particles to the molecular separation combine in transmitting the velocity of the motive fluid to the available working surfaces of the rotors.

In our turbine, we present, by the sides of the partitions and the surface of the spiral ways, a maximum surface for the fluid to act upon, thereby materially increasing the power obtained.

lVhat we claim to be new is A turbine comprising a casing. a shaft journaled therein, a shell fastened to said shaft, a series of spiralpassageways, the inner ends of which communicate through circumferential openings in said shell, said passageways separated from one another by partitions, a portion of said shell extending laterally of the passageways within said shell and having openings communicating with an exhaust port, as set forth.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
