vWILLIAM D. LABADIE, OF SOUTH BEND, INDIANA.

ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 766,707, dated August 2, 1904.

Application filed December 13, 1902. Serial No. 135,131. (No model.)

To all whom it may concern.-

Beit known that I, VVILLIAH D. LABADIE, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Rotary Engines; and I do hereby declare the followingto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to rotary engines.

The object of the present invention is to provide a rotary duid-actuated motor of simple and inexpensive construction adapted to be employed as a driving means for rotary tools of diderent description, and more especially designed for use in connection with a rotary cuting-tool for removing incrustation from tubes and flues.

The invention is illustrated in the accompanying drawings, in which- Figure l is a longitudinal section of the fluid-motor with the cone shown in side elevation. Fig. 2 is a plan View of the cone removed. Fig. 3 is a detail view of the end of one of the nozzles. Fig. #L is a plan view of the cutters assembled.

In carrying out the invention the driving mechanism for the cutters may be arranged in any convenient form of casing; but the preferred embodiment is shown in Fig. l of the drawings, in which a casing l of substantially cylindrical shape, having a closed semispherical lower end 2 and an open upper end 3, is employed.

In the semispherical end is formed a substantially semicircular conduit 4, having' a coupling' 5 between the ends thereof adapted to connect with and permit the supply of motive power, which may be either water or air, preferably the former. The ends of the conduit terminate in contracted nozzles 6, which extend inwardly into the casing to eject a jet of water or air against a wheel 7.

The wheel 7 consists of a cone-shaped member having radially-disposed and longitudinally-curved blades 8, which gradually increase in breadth from the ends toward the center, so that the broadest portion of the blades is opposite the nozzles to provide an increased contacting' surface for the water ejected therefrom, the opposite ends of each blade lying in the same radial line. This wheel is provided with an axle 9, journaled at one end in a boss l0, formed in the wall of the conduit, and the other end of the axle 9 is journaled in a removable bearing ll, fitted in the hub 1-2 of a ring 13, which is screwed into the open end 3 of the casing. To reduce the friction on the wheel 7, a suitable thrust ball-bearing 14 is provided at each end thereof.

A shaft l5 is connected to the axle of the cone-wheel by a universal joint 16, which permits the cutter to operate in curved iiues, although the axle may be a continuous shaft for straight liues.

On the end of the shaft 15 are the cutters 1T, which consist of a plurality of rings having' spokes 18 and cutting-teeth 19. The upper or outer ring is of less diameter than the inner succeeding rings, so that the outer and smallest ring will penetrate the surface of the incrustation in the flue and the larger succeeding rings will cut deeper into the incrustation until the whole is removed and the last and largest ring scrapes the surface of the flue. In this way a gradually-increasing cut is provided, each cutter penetrating only a portion of the incrustation, and thus the strain on each cutter and the power required to operate them is reduced. The water which escapes from the open end of the casing passes into the iiue through the openings between the spokes of the cutter and carries od the debris, so that the movements of parts are not obstructed.

Having thus described this invention, what I claim, and desire to secure by Letters Patent,

l. In a iuidanotor, acasing having inlet and exhaust openings, and a cone-shaped member rotatably mounted in the casing and having radially-disposed and longitudinally-curved blades, the opposite ends of each blade lying in the same radial line.

2. In a fluid-m otor, a casing having inlet and exhaust openings, and a cone-shaped member rotatably mounted in the casing and having radially-disposed and longitudinally-curved blades that gradually increase in breadth from IOO the ends toward the center, the opposite ends of each blade lying in the same radial line.

3. In a device of the class described the combination of a casing having a closed end and an open end, a cone-shaped member rotatably mounted in the casing and having radially disposed and longitudinally curved blades, broadest midway their' ends, and a conduit formed in the closed end of the casing, said conduit terminating' in nozzles arranged to direct the impact of the fluid against the broadest portion of the blades.

4. A fluid-actuated motor comprising a casing, a rotary driven member therein having curved blades on its periphery, and ka longitudinally-disposed conduit terminating in nozzles that project inwardly from opposite sides of the casing toward opposite sides of the rotary driven member.

5. In a device of the class described, the combination of a cylindrical casing having an open end and a closed end provided vwith an approximate semicircular conduit disposed longitudinally of the casing, said conduit terminating in inwardly-directed nozzles, a coneshaped member mounted in the casing with l its smaller end journaled in the closed end of the casing and provided with longitudinally- Vpresence of two witnesses.
