ROTARY ENGIN E.

SPECIFICATION forming part of Letters Patent No. 623,750, dated April 25, 1899.

Application filed July 16, 1898. Serial No. 686,137. (No model.)

T0 to wltont it may concern.-

Be it known that 1, CHARLES L. WEIHE, a citizen of the United States, residing at New Minden, in the county of WVashington and State of Illinois, have invented certain new and useful Improvements in Rotary Engines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in rotary engines; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a vertical elevation of my device. Fig. 2 is a horizontal section taken on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 1. Fig. 4 is an elevation of the upper end of the drive shaft and wings carried thereby, between each pair of which the movable pistons or blades are mounted; and Fig. 5 is a section on line 5 5 of Fig. 3, taken through the spaces between the wings, the lower section of the cylinder being shown partly broken away and the shaft in elevation.

The object of my invention is to construct a rotary engine which shall be simple, one which shall operate noiselessly and with a minimum amount of friction, and one possessing other and further advantages more apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents the upper section, and 2 the lower section, of the steam -cylinder, the two sections being secured together by bolts 3, passed through the

flanges

4 and 5 of the respective sections. The flange of the lower section is extended beyond that of the upper one, the extension serving as a means for mounting the engine to any convenient base or support. (Not shown.) Passing through an ordinary stuffing box or gland 6, carried by the lower section 2, is a depending drive-shaft 7, to whose lower end may be secured a series of fanblades 8 and whose upper end terminates in a supporting-flange 0, by which the shaft is carried, the base of the flange being mounted on roller-bearings 10, which travel in a groove 11, formed between an inner annular ledge 12 and the inner surface of the section 2. The ledge 12 is sufliciently depressed below the plane of the inner surface of the section 2 to bring the upper face of the flange 9 flush with said surface. (See Fig. 5.) The shaft 7 is mounted eccentrically to the inner curve of the vertical walls of the cylinder, theupper face of the flange and the adjacent surface of the section 2 serving to support during the rotation of the shaft the cross blades or pistons 13, which are constrained to follow the vertical walls of the cylinder, being guided in their reciprocation resulting from such constrained movement by the adjacent edges of the vertical wings 14, between which the blades pass, the upper edges of the blades being substantially flush with the upper edges of the wings. The length of each blade is very nearly equal to the full diameter of the circle about which the vertical walls of the cylinder are described, the blades being permitted to span one another by cutting away a portion of the body of each along their adjacent sides, one blade being supported along the full length of its loweredge, and the spanning blading resting on the portion of the lower edge remaining on each side of the cut-awayportion. (See Fig. 5.) The section in Fig. 3 is taken alonga plane below the point where the upper wall of the passage of the exhaust-pipe 15 enters the cylinder, the continuity of said Wall with the vertical wall of the cylinder being shown by the dotted line.

The upper section of the cylinder is provided with an extension 1, through a stuffing-box 16 of which passes a steam-pipe 17. The steam-passage at the inner end or base of the extension 1 is substantially triangular in outline. (See dotted lines in Fig. 2.) The base of the triangle referred to lies along the lower edge of theinnersurface of awall 17, inclined to the exposed faces of the movable blades, the upper section 1 being so coupled to the lower one that the steam as it follows along the Wall 17 impinges against the blades.

of the position the blade occupies after the exhaust-port has been passed, it being understood that the said triangular opening is cut from the bottom wall of the upper section 1, between which and the adjacent surface of the lowerseetion the blades are confined and are free to rotate without material friction. The dotted position of the blades in Fig. 3 shows their relative position after apartial rotation of the shaft.

It is apparent that slight changes can be made in the details without departing from the spirit of my invention. It is apparent, too, that the drive-shaft may be coupled to any machinery which it is desired should be driven.

Having described my invention, what I claim is 1. In a rotary engine, a cylinder comprising an upper and lower flanged section, a blade confined between the adjacent inner surfaces of the two sections and having a medial cut-away portion whereby two such blades may span each other, a drive-shaft, a flange carried at the upper end thereof, and supported directly by the lower section,wings projecting a suitable distance beyond the plane of the flange and distributed along the peripheral edge of said flange, the blades be ing guided between the wings, one of the blades resting with its full edge along the face of the flange and the surface of thelower section contiguous thereto, and the other blade resting on so much of its lower edge as remains on each side of the cut-away portion, a steam-pipe extension leading from the upper section, and an exhaust-pipe leading from the lower section, substantially as set forth.

2. In a rotary engine, a suitable cylinder comprising an upper and lower section, a drive-shaft depending from and mounted eccentricallyin the lower section, a flange at the upper terminal of the shaft for the support thereof, a series of wings projecting from and in continuation of the periphery of the flange, the wings being separated by spaces diametricallyin alinement with one another, blades confined between the basal wall of the upper section and the adjacent wall of the lower section and guided by the walls of the spaces between the wings,-and extending outwardl y beyond the wings to contact with the walls of the cylinder, and upwardly substantially flush with the upper edges of the wings, the blades having theiradjacent edges cut away to allow the same to span one another, the supporting edges of the blades being adapted to slide along the upper face of the flange and the adjacent flush surface of the bottom of the cylinder, an annular groove formed at the base of the cylinder, the inner wall of the groove being bounded by an annular ledge depressed below the inner surface of the base of the cylinder, the groove being adapted to receive antifriction-balls, a steam-supply pipe carried by, or forming an extension of the upper section and terminating in an inclined passage for delivering the driving fluid at an incline to the blades, and an exhaust-pipe, substantially as set forth.

3. In a rotary engine, a suitable cylinder comprising an upper and lower flanged section,adrive-shaft depending from and mounted eccentrically in the lower section, a flange for the support of the shaft, a series of wings projecting from and in continuation of the periphery of the flange, the wings being separated by spaces diametrically in alinement with one another, blades confined between the basal wall of the upper section and the adjaeentwall of the lower section and guided by the walls of the said spaces, and extending outwardly beyond the wings to contact with the walls of the cylinder, and upwardly substantially flush with the upper edges of the wings, the blades having their adjacent edges cut away to allow the blades to span one another, the supporting edges of the blades being adapted to slide along the upper face of the flange and the adjacent flush surface of the bottom of the cylinder, an annular groove formed at the base of the cylinder, the inner wall of the groove being bounded by an annular ledge depressed below the inner surface of the base of the cylinder, the groove being adapted to receive antifrict-ionrollers, a steam-supply pipe carried by, or forming an extension of the upper section and terminating in an inclined passage for delivering the driving fluid at an incline to the blades, and an exhaust-pipe, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
