A TTOHN /N VENTOH wiaf BY i UNITED STATES PATENT OFFICE.
EREDJ. MA'oEY,-or oN'roNAeoN, MICHIGAN.
ROTARY` ENGINE.
. STIHL.(JIFICATIOEN' forming part of Letters Patent No. 604,995, dated May 31, 189,8; l i y i Applicatin filed I une 21,1897.v Serial No. 641.662. (No model.)
To all zutojlti may concern:
Innni'o'l' steam and-i1i which a simple means is. provided for adjusting the steam cnt-oil.
I will describe a rotary engine, embodying Iny invention, and then point ont the novel features in the appended claim.
Reference i to be had to the accompanying drawings, forming apart of this specilication, in which similar characters of reference indicate corresponding parts in both views.
Figure 1 is a vertical section of a rotary engine embodying my invention; and Fig. 2 is a vertical section at right angles to Fig. 1 but showing the piston-wings in the position indiv cated by dotted lines in Fig. 1.
lteferringto the drawings, 1 designates a steam-cylinder having a power-shaft 2 extended transversely through it and eccentric thereto. Integral with orsecured to the heads y of the cylinderare 1-'in'gs.3, which are eccentric to the shaft 2,but concentric with the cylinder. The peripheral wall of the' cylinder 1 has exhaust-ports It 5 leading fromaboutits central portion and designed to communicate with an exhaust-port 6 in a head 7 on the cylinder. The peripheral wall of the cylinder is also pro vided with steam-inlet ports v8 and 9, their inlets being near the top of the cylinder. The head 7 has a steam-port 10, designed to com- .:munieate with `a hollow cut-oit valve 11, 'mounted to oseillate in the head and having an open end into which steam may enter from .Mounted on the shaft 2 is a piston-disk 13. This piston-disk is concentric with the shaft, and therefore ,its upper portion will engage with the upper'portion of the interior-of the cylinder, thus providing an abutment for the steam. The piston-disk 13 has oppositel`yextended openings 14, and in these openings piston-wings 15 and 1G are movable. The opposite ends of the inner portions of the piston-wings 15 and 1G are respectively provided with segmental straps 17 and 18, en gaging with the rings 3, and the outer ends of the piston-wings, which bear against the inner wall of the cylinder 1 and the cylinder-heads, will be provided with suitable packing-plates. At the outer ends of the openings 14C/the walls thereof are provided with segmental or concave recessesin which rocking blocks 19 may oseillate, and between the rocking blocks the piston-wings are adapted to slide as the piston-disk rotates.
Arranged in the head 7 is a'reversi'ng-valve 20, having a port 2l, designed to be turned into register with the ports 8 and 10, depending, of course, upon which direction it is designed-to rotate the piston. This reversing valve 2O has also at onel side a port 22, designed to be turned into connu unication with the exhaust-ports. The reversing-valve 20 has an outwardly-extending stem 23, Aprovided with a handle 24.
O11 the outwardlyextending stem of the valve 1l is a crank 25, ha 4ing a pin 26 extended into a link block in an are slot in a link 27, to the endsv of which link are pivotally connected eccentric-rods 2.8 and 29, operated by the eccentric-s 30 and 31 on the shaft 2. Secured to the centerof the link 27 is a bridgepieee 32, from which a link extends lto a lever 234, pivoted to the outer side of the cylinderl. This lever 34 has'a springpressed dog 35, designed ,to engage with a curved rack 36, secured to the side of the cylinder.
In operation the lever 34'will be placed in position'to provide a communication between thevalve 11 and the port 10, and the reversing-valve 20 will be placed ,in -position to provide comm unieation between the ports 10 and 8. Then the stem, operating tlm :.Qh the port 8, will act upon the piston wing 15 and rotate the piston in the direction indicated by the arrow in Fig.V 1, and when the IDO in the desired direction to change the position of the link 27, so that the eccentric-rods 2S and 29 will oseillate the valve ll to eut ol'f the steam at any point where it is desired tlnlt the expansion shall take plneeA Ol course when it is desired to reverse the motion of the engine the reversingwnlre will he rotated to place its port 2l in Communication with the ports G and il.
It will be noted that the recess or cavity 22 in the reversing-valve 20 is sufficiently broad to communicate not only with the exhaustports but with the steaminlet ports and D,
A rotary engine comprising L cylinder hav ingr exhaust-ports lending from zt head on the ylinder and extending through the periph- 2o eral wall of the cylinder and communicating' with the interior of the cylinder et about its Center, the said peripheral wall also having inlet-ports, the inlets being:r at the upper portion of the Cylinder, a reversing-valve, a holz5 low rocking vulve for controlling admission of steam, a piston disk eeeentrienlly mounted in the cylinder, and radially-movable pistonwings carried by the piSton-disk,substantinll y as specified.
