Specification of Letters Patent.

Patented Dec. 25, 1917.

Application filed October 21, 1916. Serial No. 126,955.

To all whom it may concern.

Be it known that I, Marinas A. PA'rroN, a citizen of the United States, residing at Idaho Falls, and .Stateof and useful Fluid-Motor, of which the following is a specification.

The present invention appertains' to motors, and aims to provide a novel and improved rotary motor adapted to be operated y water, steam, air or other fluid, and which is also operable as a pump.

It is the object of the invention to provide a machine of the character indicated embodying a novel construction and assemblage 'of the component elements, whereby the structure is comparatively simple and inexpensive yet practical and efficient.

With the foregoing. and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a vertical section of the motor taken at right angles to the axis of the casing.

Fig. 2 15; a vertical sectlon taken on a plane at right angles to the plane of section in Fig. 1

The motor embodies a cylindrical casing 1, having its axis illustrated, and the periphery of the casing l is provided with openings 2 and 3, one of which provides an inlet and the other an outlet. A shaft 4 extends through the casing axially thereof and is journaled through bearings 5 carried by the ends of the casing.

A cylindrical rotor 6 is rotatable within the casing, and bears upon the cylindrical surface of the casing 1 between the inlet and outlet, to provide a crescent-shaped chamber between the rotor and periphery of the casing. the ends of the rotor working adjacent to the ends of the casing. The rotor 6 comprises a plurality, in this case four, segmental-shaped sections 7 co-extensive in length with the rotor, and connected at their ends by outstanding rings 8 which are rotatable in annular grooves 9 with 111 the county of Bonneville Idaho, have invented a newv disposed horizontally, as

'to the outlet in either which the ends of the casing are provided eccentrically relative to the shaft 4. Suitable anti-friction balls 10 or other antifrietion means can be provided for reducing the friction between the rings or ribs 8 and the casing. The sections 7 of the rotor provide V-shaped pocliets 11 therebetween which permit of the oscillatory movement of the flat blades 12 which are disposed axially within the casing 1. The ends of the blades work adjacent to the ends of the casing, and the outer edges of the blades bear against and Work around the cylindrical interior surface of the casing. The inner edges of the blades 12 are provided with alining sleeves 13 fitted upon the shaft 4, and the sleeves of one blade 12 are keyed upon the shaft, whereby the rotor in being operated will operate the shaft, although when the device is operated as a pump, the shaft in being operated will actuate the rotor by moving the blade which iskeyed to the shaft. c

In order to prevent leakage and permit of the oscillatory movement of the blades 12, the sections 7 of the rotor are provided at the outer ends of the pockets 11 with complementing longitudinal concaved seats 14 in which packing strips 15 are seated. The strips 15 are co-extensive in length with the rotor and are of sector-shaped cross sec-- tion, their curved faces seating in the seats 15 and their flat faces bearing against the opposite sides of the blades 12. As the blades 12 are oscillated relative to the rotor in the pockets 11, the strips 15 are oscillated, and will close the spaces between the blades 12 and rotor sections 7.

When the device is operated as a motor, fluid is delivered into the casing and in passing around the crescent-shaped chamber will force the blades 12 around with it. thereby actuating the rotor and shaft 4. When the device is used as a pump, the shaft 4 is operated to rotate the rotor, which will cause the fluid to be moved from the inlet direction, according to the direction in which the shaft 4 is ro- 'tated.

Having thus described the invention, what is claimed as newv is:

A device of the character described, comprising a cylindrical casing having an inlet and outlet in its periphery, a shaft extend- Ling Within the casing axially thereof, a cylindrical rotor within the casing bearing against the periphery thereof between the inlet and outlet, said rotor embodying segmenta1-shaped sections having their ends bearing against the ends of the casing, rings united with the ends of said segments and of smaller diameter than the rotor, the ends of the casing having annular grooves in which said rings are movable, the rotor having V-shaped pockets between the segments, and said segments having longitudinal concaved seats between the periphery of the rotor and said rings, blades disposed radially Within the casing and Working in said pockets, the outer edges of the blades bearing against the periphery of the casing,

the inner edges of the blades having sleeves embracing the shaft, the other edges of the blades bearing against the ends of the easing and extending across said rings and grooves, and packing strips of sector-shaped section seated for oscillation in'said seats and bearing against the opposite sides of the blades. I

In testimony that I claim the foregoing as my ovvn I have hereto afiixed my signature in the presence of two Witnesses.
