TURBINE.

Application filed October 2, 175523. Serial No. 666,156.

To ZZ 'fw/iam may concern:

Be it known that I, LARRY E. Goararnn, a citizen of the United States, and a resident of Pontiac, in the county of Oakland and State of Michigan, have invented a new and Improved Turbine, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in engines, and it pertains more particularly to engines of the rotary turbine type.

It is one of the objects of the invention to provide a new and improved rotor structure for turbine engines,

t is a further object of the invention to provide a new Yand improved structure of turbine engines in which there are a plurality of'impelling elements simultaneously operated.

-t is a further object ofthe invention'to provide av new and improved control for Vturbine engines, which `control serves to regulate the pressure of steam introduced to the rotor of the turbine.

fit is a. further object of the invention to provide a new and improved mechanism whereby the impelling'iiuid introduced to the turbine may be maintained within the limits of a predetermined pressure.

lith the above and other objects in view, reference is had to the accompanying drawings, in which- Figure 1 is a transverse vertical section of a turbine constructed in accordance with the present invention;

Fig. is a view in elevation of the turbine rotor;

Fig. 3 is a longitudinal vertical sectional view of the turbine taken on the line 33 of Fig. 1;

Fig. 4 is a view in end elevation of the rotor showing the rotor shaft in cross section.

Referring more specifically to the drawings, the turbine comprises a base 5 and a housing which is cylindrical in form, the lower portion 6 of the housing being formed integral with the base 5. The other half of the housing is designated by the reference numeral 7, and is secured to the portion 6 thereof by means of bolts or the like, 8.

The reference numeral 9 designates an exhaust, of which there are three in the present instance, and leading from each of the exhausts 9 there is a pipe 10 connected to apipe 11 by a coupling 12, which pipe 11 is connected to an exhaust manifold 13.

The upper portion 7 of the housing is provided with a plurality of intakes 14, connected by means of a pipe 15, to a threeway coupling 16, and by means of the 'pipes 17 and 18 and a coupling 19, the three-way coupling 16 communicates with the intake manifold 20. Secured to the leg 21 of the three-way coupling 16, there is a pipe 2:2, and secured to the pipe 22, there is a valve 23, the seat of which is designated by the reference numeral 24. The reference numeral :25 designates a valve member provided witha stem 26 surrounded by a spring 2T,

the upper end of which spring engaging the inner end wall of a cap 2S screwthreaded, as at 29, into the body of the valve y23; The lower end of the spring 27 engages thevalve member Leading from the valve Q3, there isa pipe 30, connected by means of a coupling 3l and afpipe 32 to a secondary exhaust manifold 33. The operation of the foregoing mechanism willbe hereinafter described.

The housing members 6 and 7 are formed with recesses 35, and mountedlin such recesses are bearings 36 of the anti-friction type. At one end the housing is extended, as at 37, and mounted inthe bearings 36 therev is a shaft BS, such shaft having an 'extension 39 mounted in the extension 37 of thediousing. The shaft 3S has spaced threaded sections 40, and mounted within the threaded sections 40 are members 4l, which form end plates of the rotor. The rotor comprises a cylindrical member 4:2, and the end plates are secured to the cylindrical member 42 by bolts, screws, or the like, 43. The cylindrical member and the end plates 41 are retained in adjusted position upon the shaft 38 by nuts or the like, 44.

The two members 5 and 6 of the housing are provi-ded with alined channels 45, and the cylindrical member is formed with channeled flanges or rims 46 adapted to project inwardly of the channels 45 in the members 5 and 6 of the housing, and at the point of ljuncture of the cylindrical member with the members of the housing, there are contact elements 47, set in recesses in the housing members and the cylindrical member of the rotor.

Mounted in each of the channeled flanges 46 of the rotor are two sectional annular members 50, and such sectional annular lltl members 50 are secured in position by bolts, or the like, 5l, Which pass through the cylindrical member of the rotor, as shown in Fig. 1. These sectional annular members are formed `With radial projections 52 spaced With respect to one another to provideJ 'intervening pockets 53, and the rotor is of such construction that the projections Will pass in the presence of the intake passage 14 as the rotor travels in a rotary path.

Leading through the upper member 6 of the housing there are a plurality of passages 55, and each of the passages 55 has communication with a pet cock 56, the purpose of Which Will be hereinafter described.

The operation of the device is as follows: The elements Vforming the rotor being arranged in parallel, steam is admitted by Way of the intake port 11i to the interior of the housing, and in the presence of the proj ections 52 of the sectional annular members 50 of the rotor and imparts rotary movement to the rotor, the same exhausting through the exhaust passage 9.

In order to regulate or predetermine the ,pressure at Which the ste-am is admitted to the rotor, the valve 23 heretofore mentioned is employed, and by screwing the cap 28 until it places the spring 27 under the desired tension, the valve 25 Will be held to its seat until the predetermined pressure of fluid has been exceeded. For example, if the cap isscrewed and the spring 27 is placed under compression to a predetermined point, say to permit steam of sixty pounds to enter the turbine, immediately the steam pressure exceeds sixty pounds, the valve 25 Will open and reduce the pressure allowing the predetermined pressure to enter the housing of the turbine.

In order to determine the condition of the packing, it is only necessar to open the pet cocks 56. The presence o fluid in the space with which the pet cocks communicate, indicates a leaking condition of said packing o By this construction it is apparent that the Valve 23 serves to regulate the pressure of the steam or other fluid employed to operate the turbine, and through this medium serves to maintain the steam of the turbine constant, all Within certain predetermined limits.

I claim:

l. In a turbine, a rotor assemblage, said rotor lassemblage comprising a shaft, a plurality of plates carried by the shaft, a

Vcylindrical member surrounding said shaft and supported by said plates, and sectional annular members secured to the outer surface of said cylindrical' member, said sectional annular members being formed With pockets. f

2.- In a turbine, a'rotor, said rotor comprising a shaft, a cylindrical member carried thereby, a plurality of integral spaced flanges formed in the periphery of said cylindrical member to provide spaced channels, sectional annular members formed on their outer periphery With projections, said sectional annular members adapted to be received Within said channels, and bolts passeing through the Walls of said cylindrical member into engagement With the sectional annular members to secure them in their respective channels.

3. In a turbine, a rotor comprising a cylindrical member provided With spaced` peripheral channels, and pocket members mounted in said channels, said pocket mem bers comprising sectional annular members adapted to embrace said cylindrical member and occupy a position Within the channels thereof.
