ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 535,337, dated March 5, 1895.

Application filed March 10. 1894.

To all whom it may concern.-

Be it known that I, JOSEPH WEST, a citizen of the United States, residing at Galveston, in the county of Galveston and State of Texas, have invented a new and useful Rotary Engine, of which the following is a specification.

My invention relates to improvements in rotary engines by which a flanged or bladed disk is made to revolve in a steam tight ch am ber or chest. I attain this object by a revolving disk having transverse flanges 0r blades on its periphery being caused to rotate in an annular recess in a steam tight chamber by the introduction of steam through an opening or port in one part of the circumference of said chamber and striking the flanges or blades of the disk in the required direction in its passage to another opening or port for the exit or escape of the steam; thus causing the disk to revolve. I have the space in the chamber between the entrance and exit ports of the stream, flowing in the required direction, of greater diameter than the part where the blades are not intended to carry steam or that part of wall of the chamber may be suitably serrated or corrugated, thus forming a series of pockets or recesses therein,my object being by the enlargement of steam space at this part of chamber the better insuring of direction and the giving of greater pressure on the blades of the disk at that part by the steamimpinging against stationary wall at that part of the chamber, the blades rotating closely along the general circumference of the recess of the chamber at other places.

Blades may be set at any angle with disk and may be scalloped out on concave side or in place of projecting blades, hollow spaces or pockets may be sunk into the periphery of the disk without extending through its faces.

Steam may be introduced atany angle with blades and the entrance and exit ports for steam may be through either face or circumference of casing and at any desireddistance apart. Steam may also be superheated or expanded in this chamber.

By using an inflammable gas in place of steam I can by means of out off in the escape conduct the gas after passing through the en- Serial No. 503,148. (No model.)

gine back to the fire box and there use it as fuel.

For a more complete description reference is had to accompanying the drawings.

Similar lettersret'er to similar parts througlb out the several views.

Figure l is a vertical section of the machine with face of casing removed, A being steam chamber showing enlarged diameter of the recess in direction of rotationbetween entrance of steam at the portFB and its exit at the port of escape C. At D is shown the revolving disk with its transverse flanges or blades E thereon. F desighates the perimeter or outer casing. H shows axis or shaft of disk projecting through face of casing from which motion is taken.

Fig. 2 shows the same machine adapted to both forward and reverse motions, the chamber being enlarged at such places and in such position as direction may be required, blades of disk running closely to smaller circumference of chamber between the two ports of entrance B and the two ports of exit at C direction being determined and regulated by admission of steam through the cut off G. F shows solid parts of easing narrowing chamber to diameter of disk at that part. Figs. 3 and 4 show same machine in position for superheating or expanding the steam in its passage through the enlarged part of the steam chamber.

Fig. 5 shows excavations or pockets in disk in place of blades on its periphery also excavations in wall of chamber forming impact pockets for the impingement of steam thereon, parts of disk being cut away to lessen friction.

Fig. 6 is a view of that part of inner circumference or wall of chamber showing entrance and exit ports of steam and the curvilinear part of solid casing F narrowing the chamber to diameter of disk between the two ports of entrance as in machine adapted to forward and reverse motions as shown in Fig. 2.

Fig. 7 represents the machine adapted to the consuming of an inflammable gas it used in the place of steam. By means of the cut off J in the escape pipe and the conduct ing pipe K the gas after passing through the engine is led to the fire .boxand there consumedas fuel, L being the smoke or fire flue also having its vent in the escape pipe.

Among its claims to merit are: that it can be used in either a vertical or horizontal-position; its small number of parts; its simplicity of construction and mode of working; its compactness, solidity and durability. *In size it may be from the smallest toy to large enough to answer the most powerful requirements. The larger'the diameter of the disk and consequently more blades engaged the more steam would be utilized and greater power gained, while from a smaller disk extreme velocity could be obtained. Drawings are not made to scale. Neither are blades as shown proportionate to size of disk.

Wherever the word steam is used -it is intended to imply anyliquid or gaseous current of pressure.

Having thus-described my invention,-what I claim, and desire to secure by Letters Patout, is-

1. In a rotary engine, the combination ofa casing withinlet and exit ports for steam and a bladed disk ordrum mounted therein, as herein described,'the disk casingbeing provided with a steam reservoir for accumulating and distributingsteam simultaneously to' all the disk blades encompassed in their passage through it; said reservoiror steam chamber being formed by enlarging the diameter of the recess in the casing between inlet and exit ports in direction of rotationandbeing concentric with the annular recess of the casing, terminating in a curved-or straight 'rear end at the inlet point, fortheimpingement'of steam thereon, and a gradually sloping for- Ward end to point of exhaust; said reservoir also forming a steam channel embracing all the blades in their passage through it, the blades of the disk being adapted to rotate in contact with the general circumference of the recessed chamber at all other places.

'2. In a rotary engine, the combination of a casing inclosing steam chambers with a bladed disk or drum mounted therein, and being adapted to both forward and reverse motions as herein described, the casing being provided with two oppositely directed inlet ports for steam conducting to oppositely sloped orinclinedsteam chambers formingreservoirs for accumulating and distributing steam simultaneously to all the disk blades encompassed in their passage through them; said steam chambers 0r reservoirs being formed concentric with andlocated in the annular recess of encompassed with steam in their passage through either chamber or reservoir to which steam is admitted, and passing freely through the oppositeemptyreservoir, the-direction of rotation being determined by admission of steam into-andthrougheither chamber.

3. In a rotary-engine,the combination of-a easing 'in'closing a steam chamber with a bladed'or bucketed drum mounted therein,

the chamber being provided with two oppositely'directed inlet ports for steamconducting through oppositely sloped or inclined impactlpockets formed in the wall or inner circuinferenceofthe said chamber, one set leading in-onedirection andonesetleadingin the opposite-direction to port'ot escapeor'exhaust, the disk-or'd'rum blades having their steam faces oppositely curved or inolinedso as to engagewvit'h either set of steam pockets in wa'llof chamber; ad missionotstea'm through either-inlet port-determining'the direction'of rotation.

4. lnarotaryenginecomprising-the casing,

chamber-and disk as h'ereiubeforedescribed the combination'of the cutoff in the exit or exhaust port in connection with the channel or conducting flue leading down or back to the firebox for the consuming of-gas when an inflammable gasis used in place of steam.

5. In a rotary engine thecombination o'tthe casing, steam chamber, disk or drum,the arrangement forexpauding steam inthe engine, theout off "valve in the exhaust'and the returning channel from exhaust back to the fire box, all substantially as described and shown.
