UNITED STATES PATENT OFFICE.
ADOLPHMICHAEL, or EILENBURG, GERMANY.
ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent No. 720,834, dated February 1'7, 1903.
Application filed August 21, 1901.
To all whom it may concern:
Be it known that I, ADoLPH MICHAEL, a subject of the King of Prussia, Emperor of Germany, residing at Eilenburg, Kingdom of Prussia, Germany, have made anew and useful invention in Improvements of Rotary Engines, of which the following is a full and exact specification.
The present invention relates to rotary engines; and it consists of the details of construction hereinafter set forth, and particularly pointed out in the claim.
In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.
Figure 1 is an end elevation of the engine; Fig. 2, a section on line N N of Fig. 1; Fig. 3, a section on line M M of Fig. 1; Fig. i, a detail face view of the piston; Fig. 5, an end View of a ring placed within the cylinder; Fig. 6, a face view of two disks employed with the piston, and Fig. 7 a detail view of one of the piston-heads.
The housing A is bored out comically and provided with the covers B, having stuffingboxes and glands for the shaft 0, which passes through them and is provided with an enlarged central part. The piston D is centrally mounted on the said shaft 0 and provided with four or more radially-arranged sliding piston-heads M, adapted to be projected in and out of the guideways K of the said piston. The said piston is further provided with two face-disks E, each having an inwardlytnrned flange, and each disk having guideslots K for the piston-heads M, the said slots not extending to the edge of the disks, but forming limitations for the outward movement of the piston-heads. The object of this arrangement is to prevent the piston-heads from rubbing the interior surface of the ring G, against which they are adapted to act. Inserted between the housing and the adjacent faces of the piston-heads is an eccentric ring G, Fig. 5. This ring is not a true eccentric, but is provided with two concentric parts G and G and two intermediate eccentric parts G and G The concentric part G Serial No. 72,836. (No model.)
fits the circumference of the piston D, while the concentric part G forms the guidesurface for the faces of the piston-heads in their ext-ended positions. The eccentric parts G and G are provided with slots J, and the whole ring is supported rigidly in the hous ing by means of a screw F, the said slots being in communication, respectively, with the steam inlet H and outlet H. The faces of the piston-heads M are provided with grooves L, Fig. '7, by means of which the steam or other fluid has free access to the spaces K behind the said piston-heads, so that they are entirely free to be projected out of their guideways as far as the flanges of the disks E allow and inwardly again by the eccentric parts of the ring G.
The engine works in the following manner: Steam enters at H and passes through the slot J of ring G, acting on the piston-head in front of it and forcing the same along the concentric part G of the ring G. As soon as one piston-head has left the ring part G the next will have reached it, thus forming the cut-off, and the steam between the two pistonheads will pass round and out at the exhaustport H. The closure of the piston and the piston-heads against the upper concentric part G of the ring G prevents the steam from passing to both sides of a head, and the engine may be reversed by simply using the exhaust-port H as steam-inlet port andthe inlet H' as exhaust, as will be readily understood. The conical boring of the housing A enables the piston-disks E to be easily and conveniently tightened up and adjusted, and the flanges of the said disks E allow the edges of the piston-heads to just contact with the concentric parts of the ring G, but not to rub violently against the same and form a brake for the piston.
I claim as my invention- In arotary engine the combination of ahousing having a conical boring arotary piston concentrically mounted therein and having radial guideways therein, radially-movable pistonheads in said guideways, and disks at each side of the said piston, having limiting-slots therein for the said piston-heads, and having inwardly-turned flanges lying within the conposite sides of the piston the inlet and outlet ports substantially as described.
In witness whereof I have hereunto set my hand in' presence of two witnesses.
ADOLPI-I MICHAEL. Witnesses:
