ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 678,652, dated July 16, 1901.

Application filed January 29,1901. Serial No. 45,254. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY FRANKLIN FAR- LEY, a citizen of the United States, and a resident of Kalona, in the county of Washington 5 and State of Iowa, have invented a new and Improved Rotary Engine, of which the follow ing is a full, clear, and exact description.

The object of the invention is to provide a new and improved rotary engine which is simple and durable in construction, very ef: fective in operation, and arranged to permit of convenient reversing and of utilizing the motive agent to the fullest advantage.

The invention consists of novel features I and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views- Figure 1 is an end elevation of the improveinent. Fig. 2 is a transverse sectional side elevation of the same. Fig. 3 is a sectional side elevation of the same on the line 3 3 in Fig. 1. Fig. 4 is a sectional plan view of the same on the line 4 4 in Fig. 1. Fig. 5 is a perspective view'of one of the abutments, and 0 Fig. 6 is a face view of the exhaust-valve.

The cylinder A is mounted on a suitablyconstructed base B, and in the cylinder-heads is journaled the main driving-shaft O, carry ing a piston D concentric with the cylinder 3 5 and provided with piston-heads E E, located diametrically opposite each other and mounted to slide in recesses formed in the piston D, springs E pressing the said piston-heads outwardly to hold their outer ends in contact 0 with the inner surface of the cylinder A. On opposite sides of the piston D are arranged abutments F F, of which only one is active at a time, each abutment when in use forming a supply-chest of the motive agent for the cylinder, as hereinafter more fully described. The abutments F F are made hollow for this purpose and are fulcrumed on supply-pipes G G, extending to the outside of the cylinder and connected with a main supply-pipe G leading to a boiler or other suitable source of motive-agent supply. The ends of the pipes G G within the cylinder are perforated,

as shown in Fig. 4, so that the motive agent can pass from the pipes into the hollow abutments F FQ ments F F are formed with openings F through which passes the motive agent into the cylinder to rotate the piston D.

When the abutment F is in use, as shown in Fig. 2, then the motive agent passing into the cylinder acts successively on the heads E E to turn the piston D in the direction of the arrow a. When it is desired to reverse the engine, the abutment F is moved outward into a recess A, formed in the cylinder A, while the other abutment F is moved from its recess A into the cylinder, so as to become the active abutment, and then the motive agent passing from this abutment F into the cylinder acts on the piston-heads E E to ro- 7o tate the piston D in the inverse direction of the arrow a. The under sides of the abutments F F are curved, as is plainly indicated in Fig. 2, so that when the piston-head E or E comes in contact with the said under side then the corresponding piston-head is pushed inward against the tension of its spring E to pass the abutment, and as soon as this takes place the spring E again forces the corresponding abutment outward to take steam.

The abutments F F are simultaneously moved by mechanism under the control of the operator-that is, when one abutment moves into an active position the other moves out of an active position. For the purpose described the abutments are provided with stems H H, extending through the walls of the recesses A A to the outside of the cylinder, and theouter ends of the said stems H H are connected by links I I with alever 0 J, fulcrumed on the driving-shaft O and provided with a hand locking device J adapted to engage a notched segment J secured on the cylinder-head. When the'operator unlocks the lever J and swings the same from the left to the right to the position shown in Fig. 3, then the abutment F is moved into an active position, while the abutment F is moved into an inactive position--that is, outward into the recess A. When the lever J too is swung from the right to the left, then the abutment F is swung inward into an active The forward ends of the abut- 55 position, while the abutment F is swung out-- ward into its recess A to become inactive.

In order to control the amount of motive agent passing from the abutments F F into the cylinder at the time an abutment is in an inactive position, I provide slide-valves K K over the openings F of the abutments, and said slide-valves are provided with stems K K each of which carries at its outer end an adjustable collar K connected by a link L with a lever L, fulcrumed on a bracket N, attached to the, corresponding stem H or H of the abutments F or F. L is connected by a link L with a hand-lever 0, having a locking device 0, adapted to engage a segment P, pivotally connected with said bracket N, and with a link P, fulcrumed on the cylinder A, as is plainly shown in Figs. 1 and 2. The lever O is fulcrumed on the se ment P, and the latter moves with the corresponding bracket N when the abutments F F are shifted by the operator manipulating the lever J, as above described.

By the operator operating the hand-lever O a swinging motion is given to the lever L, which by the link L and collar K imparts a sliding motion to the corresponding valve K or K, so as to shift the same relatively to the opening F to allow more or less motive agent to pass into the cylinder A, according to the direction in which the hand-lever O is shifted.

The exhaust in front of a pistonhead takes place through an exhaust-port a, formed in a circular valve R,,(see Figs. 3 and 6,) extending between the front face of the piston D and the cylinder-head A and mounted to turn loosely on the shaft 0. The port oregisters with a segmental exhaust-channel Q, formed on the inner side of the cylinder-head A and leading to an exhaust-pipe Q, as is plainly indicated in Figs. 1 and The exhaust-valve R is connected with a hand-lever S, fulcrumed on one of the cylinder-heads by means of a pin S, extending through a segmental slot S formed in said head A of the cylinder. The lever S is provided with a locking device S for locking the lever on a segment S and holding the valve R in the desired position-that is, with its port 0. either at the right or the left portion of the exhaustchannel Q. When the abutment F is in use, the valve R closes the left-hand half of the exhaust-channel Q, and when the abutment F is in active position then the operator has to shift the valve R to bring the port a to the right-hand half portion of the channel Q.

A packing and an adjusting disk T is arranged between the cylinder-head A and the rear face of the piston D, and set-screws T, screwing in said head, serve to adjust the disk transversely to hold the piston in proper contact with the exhaust-valve and prevent leakage of steam.
