ROTARY STEAM-ENG l N E.

SPECIFICATION forming part of Letters Patent N0. 601,696, dated April 5, 1898. I Application filed April 29, 1897. Serial No. 634,401. (No model.)

T0 at whom it may concern.-

Be it known that I, ANTON ZWIEBEL, a citizen of the United States, residing-at Burlington, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Rotary Steam-Engines; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to rotary steamengines; and the object is to simplify the construction and to provide a valveless engine which may be run with a minimum amount of steam expenditure and generate a maximum amount of force or power.

With this object in view the invention con sists of certain features of construction and combination of parts, which will be hereinaft'er fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved rotary engine. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail perspective view of the rotary piston removed. Fig. 4 is a cross-section through the engine.

In said drawings, 1 denotes the engine-cylinder, 2, its base or pedestal; 3, the cylinderheads; 4, the rotary piston, and 5 the piston rod, to the outer end of which is adapted to be secured a power-transmitting device or mechanism,illustrated in the present instance as a pulley 6. p

The piston on one end is provided with a semicircular recess which extends about half around that end of the piston, and one end wall of this recessis vertical to form a steamimpacting shoulder 7, while the other end wall is inclined to form means for actuating the impacting-heads hereinafter described.

The side wall of this recess is provided for a portion of its length with transverse apertures 8, which communicate with vertical apertures 9, arranged directly below the steaminlet port 15. The other end of the piston is constructed in identically the same manner with the exception that the recess is on the opposite side of the piston.

7 denotes the impacting-heads hereinbefore referred to. These heads are pivoted in the ends of the casing and extend the full width ofthe recesses in the cylinder.

A rod 12 is supported upon the cylinderhead by a spring-actuated cap 13, and the ends of'this rod are provided with links 14, connected to the impacting-heads.

1O denotes exhaust-ports in the cylinder.

In operation as the steam enters the cylinder through its steam-port it passes through one series of verticalapertures and is conducted out between the impacting-shoulder at one end of the piston and the impacting head which is'located in that particular re: cess. The steam, being confined between these impacting surfaces, will rotate the cylinder, and as it is being rotated each successive vertical aperture will be presented to the steam-inlet. I When the last aperture of this series has passed the steam-inlet port, the steam acts expansively from point A to point B in the rotation of the piston. At the very instant the actuating-shoulder of the piston touches the impacting-head that has just been performing its duty theimpacting-head at the other end of the cylinder will drop downward and engage the recess at that end of the piston, and the steam will then be conducted through the other set of vertical and transverse apertures between the impactingshoulder of the piston and the impactinghead, and the operation will be identically the same as hereinbefore described.

By connecting the impacting-headswith the bar it is evident that when one head is raised the other will be positively lowered into on gagement with the opposite recess, thus making it impossible for the impacting-heads to fail in their operation by being clogged with lubricants.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

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

1. In a rotary steam-engine, the combination with a cylinder provided with inlet and exhaust ports, of a rotary piston arranged within said cylinder and provided at its ends on opposite sides with semicircular recesses,

one of the end walls of each recess being provided with an impacting-shoulder and the other with an actuating shoulder, and the side wall of each recess being provided with transverse apertures communicating with vertical apertures arranged to come opposite the inlet-ports of the cylinder, the vertical apertures of one set being in line with the vertical apertures of the other set, and impacting-heads secured to said cylinder and adapted to successively engage the recesses of the piston, substantially as set forth. I

2. In a rotary steam-engine, the combination with a cylinder provided with inlet and exhaust ports, of ,a rotary piston arranged Within said cylinder and provided at its ends on opposite sides with semicircular recesses, one of the end walls of each recess being provided with an impacting-shoulder and the other with an actuating-shoulder, and the side wall of each recess being provided with trans verse apertures communicating with vertical apertures arranged to come opposite the inlet-ports of the cylinder, the 'vertical apertures of one set being in line with the vertical apertures of the other set, impacting- ANTON ZWIEBEL.
