To @ZZ 'wh/Unt it may concern;

Be it known that I, ALBERT GLiDiE, a subject of the King of Norway, and a residentJ of the city or New Y'orx, borough of Manhattan, in the county and btate or N ew York, have invented a new and improved Rotary Engine, of which the following is a` full, clear, and exact description.

'lhis invention relates to certain improvements 4in rotary engines adapted to be operated by steam, compressed air, or other nuid under pressure, and the object of the inveiition is to provide certain improvements in the means for controlling the admission and exhaust of saidmotive nuid in order to gain the maximum eliiciency.

The invention consists in certainfeatures of construction and combination orl parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.`

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts iii all the iigures, in whichl! igure 1 is an end elevation of the engine, a portion thereof being broken away. rig. 2 is a side elevation, a portion thereof being broken away to show the throttle-valve. Fig. 3 is a detail showing the piston, abutment, and inlet and exhaust ports. Fig. 4 is an end elevation, the valve being removed and the valve-chamber being shown in section. Fig. 5 is a plan view of the complete engine. Fig. 6 is a transverse section talen on a plane through the controllingvalve. Fig. 7 is a plan view of a portion of the device, the superstructure being removed. liig. 8 is a detail showing the eccentric for operating the abutment. lig. 9 is a detail showing the reverse side of the parts illustrated in Fig. 8. Fig. 10 illustrates details of the valve-operating mechanism, and Fig. 11 illustrates details of "the abutment.

1n the specific embodiment of my invention which I have illustrated in the drawings I employ a casing made up of 'two parts 10 and 11, bolted together and having an annular chamber 12, circular in cross-section, formed within the casing. The casing is supported by suitable standards 13, resting upon a base 14, and the standards are provided with journal-boxes 15 for supporting the main shaft 16. This shaft extends through the casing centrally of the annular chamber,

and rigidly mounted uponthe shaft is a plate or wheel 17, having its outer circumferential edge 18 extending through a slot in the innerv wall of the annular chamber or cylinder 12 and serving io close the latter. ln orderto provide a perfectly-tight joint, the Wheel 17 is provided with annular flanges 19, spaced a short distance from the innerusurface of the' casing, and intermediate these flanges and the casing is provided a packing held in place by the annular packing-rings 20, supported upon the cylinder, as shown in I* ig. 2.

As previously stated, the chamber or cylinder 12 is circular in cross-section, and the wheel 17 extends through the casing to the inner side of the chamber. Within the chamber and rigidly secured to the wheel 17 is a circular piston 21, completely closing the annular cylinder and adapted to move through said cylinder and cause the rotation of the Wheel 17. rlhis piston may be of any suitable character, but is preferably composed of a plurality of layers rigidly bolted together, one of said layers being integral With or rigidly secured to the wheel 17 In order to cause the movement of the piston 21 within the cylinder 12, l provide suitable inlet and exhaust ports for the motive iiuid and a suitable valve for controlling said ports.

Preferably the section 10 of the main cas'- ing is provided with an extension 22 integral therewith, and within this extension is provided a cylindrical valve-chamber 23, directly above the main shaft 16. Within this valvechamber is located a valve 24, the shape of which is more clearly shown in Fig. 7, and which has a passage 25 extending therethrough intermediate the two side Walls 26A 26. 'i'he valve is supported upon a valvestem 27, leading through a packing in the lower side of the valve-chamber, and said valve-stem terminates in an eccentric-strap- 28, surrounding and adapted to be operated by an eccentric 29 on the shaft 16. rl'he valve-chamber 23 is provided with an inlet pipe or conduit 30 and an outlet pipe or conduit 31, while the opposite side of the valvechamber is provided with a plurality ofv openings leading into the chamber or cylinder 12. As shown in Fig. 3, these passages are fourin number, two of them, 32 32,1eading into theV chamber or cylinder 12 at one side of ,the abutment, hereinafter referred to, and the other two, 33 33, leading into the'cylinderor' chamber at the opposite side ofthe abi'i't-f ment. The passage 25 through the valve 24.L

, with the exhaust-.passages is of considerably greater Width at one side than at trie other and is so formed that when rotated through a portion of a revolution the larger side of said passage remains at all times in communication with the inlet-pipe 30, while the smaller end of the passage may be brought in communication with the ports 33. As the valve does not completely hll the valve-casing, two longitudinal passages are formed extending trie entire length of the valve-casing, and both passages communicate at all times with the outiet-pipe 31 below the valve. When tne valve is rotated to bring the passage 25 in communication with one of tne sets of ports, the other ports will communicate with one of these two longitudinal passages and be in free communication with trie outlet-pipe. By reciprocating the valve Within the valve-chamber the wall of the valve may be moved across the end of the inlet-pipe 3U and completely shut off the supply,l although without interfering in any w ay During the normal operation of the engine the valve is moved up and down in its casing once during each revolution of the drive-shaft 16 and o1 the piston 21. The valve is only rotated When it is desired to reverse the direction of rotation.

ln order to cause the reciproeation of the valve Within the valve-casing, l provide the eccentric illustrated in llig. l0. 'l'his eccentric is made up of three disks rigidly secured together or formed integral. Une of these disks is round and is coiicentrically mounted upon the shaft 16, while secured to one side of this disk is a second or larger disk 34, having a notch 35 cut in its surface adjacent one side thereof. Upon the opposite side of the first-mentioned disk is a third disk 36, having a lug 37 diametrically opposed to the notcli 35 of the disk 34. 1he valve-stein 27 carries the eccentric-strap 28, surrounding the circular disk, and extending upward from the surface of this eccentric-strap are two projections 39 and 40, extending in opposite directions and having cam-surfaces. rl'he point of the projection 39 normally travels upon the surface of the disk 34, while the point of the projection 40 normally travels upon the surface of the disk 36, and the valve stem 27 is held from rotating. As the proj ection 37 strikes the cam-surface of the projection 40 the rod and eccentric-strap 2S are moved longitudinally and the projection 39 enters the notch 35 in the disk 34. rPhe opening in the strap 23 is of substantially the same diameter as the circular disk of the eccentric, but is of sufficient length to permit of the longitudinal movement of the strap as the projection 37 strikes the cam-surface of the projection 40. lt will thus be noted that the valve-stem is held stationary throughout the greater portion of the revolution of the shaft 16, but is suddenly raised and again lowered once during each revolution. By means of the improved eccentric above described all side movement of the valve-stem 27 is prevented and the valve is positively operated at the required instant.

"t the upper side of the cylinder-casing, intermediate the valve-ports 32 and 33, is located an abutment 41, capable of longitudinal movement and adapted close the cylinder or chamber 12 at this point. Upon the upper side of the casing is also provided means for guiding the abutment in its longitudinal movement, and this means pref erably comprises a casing 42, having a packing 43 at its upper end and through which the rod 44, carrying the abutment, reciproe cates. The casing 42 rigidly supports an arm 45, having a lever 46 pivoted to the upper end thereof, and this lever is connected to the iod 44 in such a manner that when the lever 46 is raised a sin'iultaiieous movement of the rod 44 is effected.

Upon the shaft 16 l provide a second but larger eccentric 47, similar to the eccentric 29, save as to size. The disk 36 carries a projection 37, adapted to engage with the cam-surface of the projection 40 on the ec` centric-strap 28, and the largest disk 34 is provided with a notch 35a, into which passes the projection 38L of the eccentric-strap when the rod 4S is moved longitudinally thereby. r1`he two eccentrics are so located upon the shaft in respect to the position of the piston 2l that the abutment 41 will remain in the position indicated in Fig. 2- namely, closing the chamber 12-and the valve will remain in the position indicated namely, permitting the motive lluid to enter the pipe 30 and pass through the passages 32 in tlie valve-chamber at one side of the piston, while the exhaust-gases may pass out through the passages 33 and escape through the pipe 31. As the piston 21 nearly com pletes its revolution, or, in other words, approaches the abutment 41, the eccentric 47 operates to move the rod 48 and simultaneously the rod 44 to lift the abutment out of the chamber or cylinder 12 to permit the passage of the piston 21. Simultaneously the valve 24 is dropped to close the inlet-port, and the inertia of the piston is sullieieiit to carry it past the abutment to a position beyond the ports At this instant the abutment is dropped. to close the chamber and the valve is opened to permit the entrance of motive huid intermediate the abutment and the piston to cause the further rotation of the latter.

ln order to reverse the engine, means are provided for rotating the valve 24, and this means preferably comprises a rod 49, secured to the valve 24 and extending up through a packing in the upper side of the valve-casing. '1`his rod is provided with a lever-arm 5l), connected by a link 51 to a lever-arm 52 on a to completely y rotatably-mounted rod 53. A handle 54 is rigidly secured to this rotatable rod 53, and a guide 55 is secured to the superstructure of the engine to control the movement of the handle 54. With the handle in the position indicated in the drawings thevalve will occupy the position illustrated in Fig. 6 and the inlet-pipe 30 communicate with the inletports 32. By moving the handle toward a horizontal position thelever-arm 52 causes the movement of the lever-arm 50 and a rotation of the valve 24 to bring the inlet-pipe 30in communication with the outlet-ports 33. The motive fluid is then delivered to the opposite side of the abutment 41 and pressure is applied to the opposite side of the pist0n 2l.

The eccentrics for operating the abutment and valve are such that it is entirely immaterial in which direction the engine is operating, as the valve will be closed and the abutment raised when the piston reaches a given distance upon one side of the valve and abutment and will be closed when the piston has passed them to a given distance upon the opposite side. Their operation is reversed by a reversal of the direction of rotation of the engine-piston.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A rotary engine, comprising a curved chamber provided with a slot, a rotary member having a portion thereof adjacent its circumference entering and closing said slot, a piston carried by said rotary member and movable within said curved chamber, a flange carried by said rotary member and substantially parallel to the wall of the chamber adjacent the slot but spaced from said wall, and a packing intermediate said iange and said wall and in contact with the body of said rotary member.
