ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 609,049, dated AAugust 16, 1898. Application iiled September 2, 1897- Serial No. 650,345 (No model.)

To all whom it may concern..-

Be it known that I, SAMUEL S. ROSE, a citizen of the United States, residing at Amador City, in the county of Amador and State of California, have invented certain new and useful Improvements in Rotary Engines; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which-form a part of this specification.

My invention relates to certain new and useful improvements in rotary engines; and my object is to provide a rotary engine which will more eectually utilize the power and expansion of steam and may be cheaply constructed.

It consists in the peculiar construction, novel combination, and adaptation of parts hereinafter described, and particularly point-` ed out in the claims hereunto annexed, reference being had to the accompanying drawings for a better understanding hereof, in which- Figure 1 is an end elevation of my newlyinvented rotary engine, part of the same being in section, showing the parts in `position to take steam from that side. The other part shows the parts in a neutral position. Fig.

2 is a vertical longitudinal section of the same. 4

Fig. 3 is a top viewof the ports and valve mechanism. Fig. l is a detached cross-sectional view of the rotary piston.

Similar figures of reference indicate corre-p sponding parts in the several views. y

A circular steam-cylinder l, having the legs or braces 2, is rigidly attached on a suitable foundation 3 and secured thereto by means of the bolts and screws 4, which are inserted in the said braces 2. A cylinder cover or head 5 is rigidly secured to the rear side of the cylinder 1 by means of the screw-bolts 6. The maindriving-shaft 7 is inserted eccentrically in the face of the cover or head 5 in a vertical line above the center of such head 5. The innerend of the said shaft 7 is rigidly secured to the center of ,the end of a revolving piston 8, which is adapted to `it in the circular grooves 9 in the head 5. On the front side of the cylinderl a cylindercover orhead 10 is rigidly secured bymeans ofthe screw-bolts 6, and in the upper portion of the said head a circular groove 11, similar to the grooves 9, is cut, into which the outer end of the vrevolving piston S is adapted to fit. In the center of the head 10 there is an opening, into which a wrist-pin 12 is inserted and rigidly maintained therein by means of a shoulder 13, which engages with the inner side of the said head 10, and a nut 14, which is inserted on the outer end of the said wrist-pin 12 and adapted to engage withthe outer edge of the head 10. The wrist-pin .12 is adapted to receive operating-fans, which are formed in the shape of a hinge or knuckle joint at 16, and their loose ends are inserted through slots in oscillating bearings 17, which are pivotally journaled in the ends on opposite sides of the said piston 8.V

18 represents bushings which are inserted in recesses in the wall of the piston 8 and adapted to engage with the oscillating bearings 17 for the purpose of relieving the said `piston of the consequential Wear. l The outer ends of the operating-fans 15 `have a groove in the end of each, into which groove a bushing 19 is inserted for the purpose of receiving the wear.

The oscillating bearings 17 are inserted in the rotating piston 8 by means of a ring 20, which is removablyattached to the face of the piston 8, thereby permitting the easy removal of the said bearings 17. The said ring 2O is also for the purpose of strengthening the said piston 3. 4The revolving piston 8 is lowith the upper side of the said cylinder, so as to prevent the passing or escapeof steam between `the said parts.

The cylinder 1 has an `interchangeable steam and exhaust port 21 in either side, near the top thereof, and the said ports 21 are convcated in the cylinder 1, so as to closely engage IOC provided with a stem 28, which protrudes d through an opening in the rear side of the said chamber 25 and is flexiby connected to the upper end of an oscillating lever 29,which is forked at its other end and provided with wheels or ball-bearings 30, which engage with either side of the tongue 31 of an eccentric or cam wheel 32, which is rigidly' attached to the shaft 7. The fulcruin for the said lever 29 is formed of an adjustable bracket 33,which is provided with a slot 34 in its base, which is inserted over a lug 35 on the side of the head A5 and secured thereto by means of a screw-bolt 36. The outer end of the said bracket 33 is adapted to receive a ferrule 37 between its parts, such ferrule having lugs or pins on opposite sides which engage openings in the end of said bracket. The ferrule 37 is inserted over the lever 29 and maintained in proper position by means of set-nuts 3S, adapted to engage with either end of the said ferrule 37, there being screw-threads cut on `the periphery of the said lever 29 for that purpose.

39 represents a steam-pipe which is mounted on, attached to, and adapted to communicate with the steam-chamber 25.

rlhe pulley 40 is of ordinary construction and is rigidly attached to the main shaft 7, from which pulley 40 power may be distributed as desired. On one end of the threeway valve 23 a nut 41 is inserted, which is adapted toengage with the rear side of the cylinder 1, and on the other end of ,the said valve 23 a flange 42 is rigidly attached and adapted to engage with the front side of the said cylinder 1. The front end of the valve 23 is provided 'with a stem 43, on which an operating-lever44 is rigidly secured by means of a nut 45. Such lever 44 has a pin 46 rigidly attached in the front side thereof, which pin 46 is inserted in a slot 47 in the center of a connecting-rod 4S,which is flexibly attached at each end to the outer ends of levers 49, which are fulcrumed on brackets 50, which extend from and are rigidly attached to the two front corners of the cylinder 1, near the top thereof. Ony either side of the steamchamber 25'an exhaust-valve 51 is inserted in a chamber 52 therefor, and such chambers 52 are connected with the ports 21 by means of the passages 53. flexibly connected to the loose ends of the levers 49 by means of the rods 54, which are rigidly attached to said valves 51. The eX- hau'st-pipes 55 are suitably attached to the said chambers 52 for the purpose of conducting the steam therefrom. A cylinder-cock 5 6 is attached to the cylinder 1 at the bottom thereof,whereby the condensed steam may be removed.

The mode of operating my improved rotary engine is as follows: The different parts having been connected and placed in normal position, the operator grasps the lever 44 and presses the saine to the left, whereupon the valve 23 is given an cighthturn, thereby The exhaust-valves 51 arey connecting the passage 22 and the chamber 25 by means of the angular slot 24. As the lever 44 is depressed the pin 4G engages with the slot 47, and by means of the connecting.- rod-43 and levers 49 the exhaust-valves 51 are opened and closed on the right and left sides,respectively. As will be seen,the steam rushes in through the passage 2G from the chamber 25 into the passage 22 by way of the angular slot 24 in the valve 23, on through the steam-port 21 into the cylinder 1, where it engages with the fans 15, which are adapted to closely engage with the walls of the cylinder 1, therefore forcing such fans around, carrying with them the revolving piston 8, which imparts in turn motion to the shaft 7 and wheel 40. The cam or eccentric wheel 32 having been suitably adjusted on the shaft 7, such cam-wheel 32 engages with the lever 29, whereupon the same engages and operates the cut-off valve 27 by means of the stem 28. As the piston 8 reaches a certain point in its rotation the supply of steam is cut off, whereupon the expansion of the steam forces such piston around until the steam engages with another fan 15, whereupon the valve 27 allows a new supply of steam to enter the cylinder, the cam-wheel 32 having been adjusted so to do. The oscillating bearings 17 are for the purpose of allowing the irregular motion of the fans 15 as the piston revolves. Vhen it is desired to reverse the motion of the engine, the lever 44 is pressed to the right, thereby directing the steam into the port on the `right side, and by the same operation the exhaust-valve 5l on the left side is opened 4and the exhaust-valve on the right side is closed. As will be seen, the steam enters the port on the opposite side and engages the fans 15 from the opposite direction, thereby vreversing' the motion of the piston and its attendant parts. When the lever 44 is placed in a vertical position, the angular slot 24 communicates with neither steam-port, and consequently allows no steam to escape. The
