RILEY DEXTER FASSETT, OF HARRIS, MISSOURI, ASSIGN OR TO HIMSELF AND GROVES R. STRONG, OF SAME PLACE.
ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent No. 595,536, dated December 14, 1897.
Application filed J' une 8, 1897. Serial No. 639,831. (No model.)
To all whom t may concern:
Be it known that I, RILEY DEXTER FAS- sETT, of Harris, in the county of Sullivan and State of Missouri, have invented new and useful Improvements in Rotary Engines,of which the following is a full, clear, and exact description.
This invention relates to rotary engines, and the object is to provide an engine of this character in which there are very few parts and in which the motive agent, such as steam, ,l may be employed to its greatest expansive capacity.
I will describe a rotary engine embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi'cate corresponding parts in all the views.
Figure 1 is a section on the line 1 1 of Fig. 2 of a rotary engine embodying my invention. Fig. 2 is a section on the line 2 2of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section showing valve and abutment mechanism similar to that shown in Fig. 1, but in a different position; and Fig. 5 is a section on the line 5 5 of Fig. 1.
The engine comprises a cylinder 1 of circular form, and extended transversely through the cylinder and having bearings in its side walls is a driving-shaft 2, upon which are mounted eccentrically the piston-disks 3 and 4. The piston-disks 3 and 4 are circular and are reversed as to their eccentricity, so that they will be evenly balanced. Mounted on the shaft 2, between the piston-disks 3 and 4, is a partition-block 5, bearing at its periphery closely against the inner surface of the cylinder.
Mounted on the cylinder 1 and extending entirely across the same is a housing 6, having steam-chambers 7 and 8, divided by a partition 9. Movable vertically in the housing 6 are abutments 10 and 11, engaging, re-
spectively, with the piston-disks 3 and 4.
These abutmentsat their opposite sides are provided with depressions 12, forming steamways. inlet pipe 13 and an exhaust-pipe 14. The partition 9 is provided with ports 15, 16,17,
Leading intothe chamber 7 is a steam-v and 18, which provide communication between the chambers 7 and 8, and the chamber 8 is placed in communication with the cylinder 1 by means of ports 19 and 2O at opposite sides of the abutments. inclusive, are controlled by a slide-valve 21, having a port 22, adapted to register with the port 15, a port 23, adapted to register with the port 16, a port 24, adapted to register with the port 17, and a port 25, adapted to register with the port 18. It will be noted that the ports to 18 are arranged in line, one directly opposite the other, and also that the ports 16 and 17 are arranged in line, one opposite the other. The ports 22 and 25, however, of the slide-valve 21 are arranged out ofline, as are also the ports 23 and 24.
It will be noted in Figs. 3 and 4 that the abutments divide the chamber 8 into two compartments'and that the ports 15 and 16 extend from the chamber 7 through the partition 9 to opposite sides of the abutments. From the valve 21 a stem 25 extends outward through a suitable stuffing-box in the wall of the housing 6 and has pivotal connection with a hand-lever 26, pivoted on an arm 27, extending frointhe housing. This hand-lever has a spring-pressed dog adapted to engage in either one of the notches formed in a segment-rack 28, so that the ports 0f the valve may be made to register more or less with the other ports to regulate the flow of steam.
Movable vertically in the housing 6 at opposite sides of the abutments are valves 29 and 30, designed to regulate the length of expansion in the cylinder. These regulatingvalves 29 and 30 bear at their edge against the abutments in line with the depressions 12. The valves are operated from the lever 26 by means of a rod 31, pivoted to the lever 26 near its lower end and pivotally connecting at its upper end with an arm 32, mounted on a rock -shaft 33. On this rock shaft 33 walking-beams34 are secured, and to the ends of the walking-beams links 35 are connected, rods 36 extending from these links to the valves 29 and 30. Y
When the parts are in the position indicated in the drawings, the engine will be taking steam to rotate the pistons in the di- The ports 15 to 18, y

rection indicated bythe arrowin Fig. l. The abutments will move downward by steampressure on top of the abutments and will be moved in their upward direction by the rotation of the pistons. Vhen the parts are in the position shown, steam will enter through the port 17 at the right-hand side of the abutment,and the pressure on the pistons will cause them to rotate, and when the pistons shall have reached suiiiciently far to move the abutments, with their depressions, above the controlling-valve 29 the steam will be cut off, and then the expansion will continue the rotation of the pistons. The exhaust at this time will be through the port 1S and out through the pipe 14.
To reverse the motion of the engine, the slide-valves will be moved to place the ports 22 and 23 in line with the ports 15 and 16, and then the steam will enter through the port 1G to the opposite side of the abutments, and the exhaust will be through the port 15 and out through the pipe 14. The exhaust portion of the chamber' 7, it will be noted in Fig. 3, is separated from the inlet portion by a partition 37.
Having thus described my invention, I I claim as new and desire to secure by Letters Patent l. A rotary engine comprising a cylinder, a shaft extended through the cylinder, a circular piston eecentrically mounted on the shaft, a slide-valve forcontrolling ports leading into the cylinder, an expansion-regulating valve, a lever having connection with both of said valves whereby they may be operated together and an abutment held against the piston, substantially as specified.
2. A rotary engine, comprising a cylinder, a shaft extended through the same, pistondisks eccentrically mounted on the shaft, a partition-disk mounted to rotate with the shaft between the pistons, a housing,r on the cylinder, abutments movable vertically in said housing and engaging with the pistons, a partition dividing the housing into compartments, the said partition having ports extended through it, a slide valve for regulating said ports,expansion-regulating valves at opposite sides of the abutments, a lever, and connections between said lever and slidevalve and also between the lever and regulating-valves, whereby all of the valves are operated togetherby said lever, substantially as specified.
3. A rotary engine, comprising a cylinder, a shaft extended through the same, pistondisks eccentrieally mounted on the shaft, a housing on the cylinder, abutments movable in said housing and engaging with the pistons, the said abutments being provided with steamways on their opposite sides, a partition dividing the housing into two chambers, the said partition having vertical ports providing communication between the chambers and also having cross-ports providing communication between the chambers, a slide valve having ports adapted to register with the first-named ports, a lever with which said slide-valve is connected, expansion-regulating valves at opposite sides of the abutments, walking-beams with which said regulatingvalves are connected, an arm extended from the shaftof said Walking-beams, and a connection between said arm and the slide-valveoperating lever, substantiallyT as specified.
