SPECIFICATION forming part of Letters Patent No. 585,333, dated June 29, 1897. Application filed February 29, 1896. erial No. 581,387. (No model.)

To a whom it may concern:

Be it known that I, J OHANN BURGERMEIS- TER, clock-maker, of Hogyesz, Austria-Hungary, have invented Improvements in Rotary Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a rotary engine in which the steam or other pressure fluid acts directly upon a vane secured to the driving-shaft.

Four different constructions of the rotary engine are shown on the accompanying sheets of drawings.

Figures 1 to 3 show, respectively, in vertical section, cross-section, and in plan one form of the engine. Figs. 4 and 5 show details of the construction. Fig. 6 is a longitudinal section, and Fig. 7 a cross-section, of a modification. Figs. 8 and 9 show another modification, while Figs. 10 and 11 show, respectively, in side view and section yet another modification.

The working of the engine shown in Figs. 1 to 5 is as follows: The semicircularblock a for controlling the steam-supply, by alternately, as it revolves, covering over or exposing the port 6, is secured to the disk I), which is keyed to and rotates with the shaft 0. This disk may have teeth on its periphery, as at Fig. 5, if it is desired to transmit power. Steam is admitted by the pipe 01 and passes through the port 6 into the cylinder 71, (see also Fig. 4,) where it acts directly upon the vane f of the shaft 0, and as a consequence causes both to rotate in the direction of the arrow. As soon as in its rotation the nave passes the exhaust-port g the steam escapes through said port into the atmosphere. The fiy-Wheel a has an elliptical cam part 19, by which the s1ide-valve m is operated. As the momentum of the fiy-wheel maintains the rotation of the shaft after the steam has escaped through the exhaust-port g, it follows that the vane f continues its rotation, and, further, the parts are so arranged that when the vane approaches the valve m the latter is lifted up out of the way by the elliptical part 10 of the fly-wheel acting on the upper exposed part m of said valve. This part m, as will be seen, Fig. 1, has friction-rollers m between which the flange of the liy-wheel passes. flywheeleventually, as will readily be understood, force the slide-valve m back again until it bears tight against the shaft 0. As a result of the continued rotation of the shaft 0 the port 6 is again uncovered by the block a and steam gains access to the cylinder h and gives a fresh impulse to the vane f until it is out off the second time by the continued revolution of said block a. The action before described continues so long as steam is supplied to the engine.

To cause the shaft 0 to rotate in a reverse direction, the outlet and inlet ports d and 9 must be correspondingly reversed.

In the arrangement shown at Figs. 6 and 7 the valve m is raised at the proper times by means of a cam-like projection 7t, fixed to the shaft 0 and to the back of the vane f. The valve is caused to fall again by means of a spring, as shown, or by gravity. The steam enters at d and escapes at t'. The supply of steam is controlled in the same way as before.

In the arrangement shown at Figs. 8 and 9 the only difference is in the distribution of the steam. The steam which enters the hollow fixed central shaft 0 at 90 passes therethrough and enters the cylinders 7t through the port y, where it acts upon the vane f and slide-valve and imparts a rotary movement to the cylinder and the fly-wheel secured thereto. As soon as the cylinder has turned sufficiently far for the arm fixed to the shaft to beginraising the slide-valve the steam will enter through the opening 0 of the sleeve .2 and finally escape through the opening 00 into the shaft 0 and from thence by the outlet y to the atmosphere.

The fourth arrangement, Figs. 10 and 11, is suitable for engines having no fly-wheel such as ships engines, for instance. In this case the steam enters through the ports d and 6 into the cylinder h and imparts a rotation to the shaft 0 and vane f in the direction indicated by the arrow until the cam-shaped projection 2, fixed to the shaft, slightly raises the slide-valve 'm, whereupon the steam forces up the valve until it uncovers the exhaustport r, through which the steam escapes.

.The vane fis so arranged as to release the slide-valve after the escape of the steam,

The continued revolutions of the whereupon it Will fall by its own gravity or under the action of a spring to its original position. Areverse rotation can be produced in this case by merely reversing the inlet and outlet ports.

lVhat I claim, and desire to secure by Letters Patent of the United States, is

1. In a rotary engine, the combination of a cylindrical casing, a rotary shaft j ournaled in said casing, a radial vane keyed to the shaft and rotating in said casing, a cylindrical steam-supply chest at one end of the casing communicating with the interior of the casing through a suitable inlet-port, a rotary head keyed to the shaft and comprising a circular plate forming the outer head of the steam-chest and a semicircular block or pro jection which fits snugly and rotates in the steam-supply chest and alternately opens and closes the steam-inlet port, a radially-movable abutment, means for moving the abutment into and out of position, and means for transferring power from the rotary shaft, sub stantially as set forth.

2. In a rotary engine, the combination of a cylindrical casing, a rotary shaft journaled in said casing, a radial vane keyed to said shaft and Working in the casing, a movable abutment projecting into the casing in the path of the radial vane, means for holding said abutment in its inner position, a cylindrical steam-supply chest at one end of the casing communicating With the interior of the easin g through a suitable inlet-port, and a rotary head keyed to the shaft and comprising a circular plate forming the outer head of the steam-chest and a semicircular block or pro jection which fits snugly and rotates in the steam-s11 pply chest and alternately opens and closes the steam-inlet port, substantially as set forth.

3. In a rotary engine, the combination of a cylindrical casing, a rotary shaft journaled in the casing, a radial vane keyed to said shaft and Working in the casing, a cylindrical steamsupply chest at one end of the casing, a rotary head comprising a circular plate fitting over the end of the steam-chest and a semi circular block projecting into the chest, a gear-Wheel formed integral With said rotary head, and a suitable radially-movable abutment having means for operating it, substantially as set forth.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.

JOHANN BURGERMEISTER.
