JOSEPH GOUGEON, OF BALTIC, MICHIGAN.

ROTARY ENGINE.

To all whom it may concern:

Be it known that I, Josnrn GoUeEoN, a citizen of the United States, residing at Baltic, in the county of Houghton and State of Michigan, have invented a new and useful Rotary Engine, of which the following is a specification.

This invention relates to rotary engines and is more particularly designed to improve the construction and operation of the engine set forth in Letters Patent No. 1,000,509, dated August 15, 1911.

The object of the invention is to provide a reversible engine of the rotary type which is provided with a series of link controlled valve gears which in turn are operatively connected with the engine shaft, means being provided for manually shifting the valves to change the direction in which the engine shall rotate, the said means including mechanism for closing one or the other of the exhaust ports of the engine in combination with fiy wheel carried and controlled governors. That it to say when the cut off valve which controls the steam to drive the engine in one direction is held closed over its port its cooperating exhaust valve is also closed. Thus when the engine is to rotate in one direction, the cut-off and exhaust valves at one side of the piston are closed while the valves at the other side are open and when the engine is to rotate in the opposite direction, the first mentioned valves are opened while the last mentioned valves are closed. The parts of the valve gears are both manually and automatically shiftable with relation to the links whereby the movement of the exhaust valves may be controlled.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings :-Figure 1 is a side elevation of the engine complete. Fig. 2 is a view of the engine at a right angle to the side illustrated in Fig. 1. Fig. 3 is a top plan view of the invention. Fig. 1 is a view of one of the fly wheels with Specification of Letters Patent.

similar view with the governor in its maximum valve operating position. Fig. 6 is a section on line 66 of Fig. 3.

The engine includes a casing l in which is j ournaled a shaft 2, two fly wheels 3 being mounted upon the respective ends of said shaft. A piston or rotor R is located in the casing 1 and is fixed to the intermediate portion of the shaft 2. A steam chest 8 is formed in the upper part of the casing 1 and a steam supply pipe 9" communicates with the said steam chest. The ports 6 and 6 lead from the interior of said chest to the chamber in which the piston 4 is located. Valves 9 and 9 are located in the chest 8 and are arranged to move over the ports 6 and 6 respectively. Operating rods 10 and 10 are connected with the valves 9 and 9 and project through the sides of the casing 1. Levers 11 and 11 are fulcrumed at sides of the casing 1 and their lower ends are pivotally connected with the outer end of the rods 10 and 10. Bars 12 and 12 are pivotally connected at their outer ends to the upper ends of the levers 11 and 11 and the said bars are provided at their inner ends with pivoted blocks 13 and 13 respectively. Links 14 and 14 are pivotally mounted on the standards 15 and 15 respectively which are mounted upon the top of the casing 1 and the blocks 13 and 18 are slidably mounted in the said links.

A shaft 16 is journaled in standards 17 which are mounted upon the top of the easing 1 and an operating handle 18 is fixed to said shaft. A segment 19 is located adjacent said lever 18 and the lever is pro vided with a spring pawl 20 adapted to engage the said segment whereby the said lever is held in an adjusted position. Links 21 and 21 are pivotally connected at their lower ends with the intermediate portions of'the bars 12 and 12 respectively and at their upper ends the said links 21 and 21 are pivotally connected with arms 22 and 22 which in turn are fixed at their inner ends to the shaft 16 and project beyond the opposite sides thereof. Both of the fiy wheels 3 are provided with governor mechanisms, whereby the respective valves 9 and 9 are automatically controlled to regulate the admission of pressure fluid to the rotor R, and each governor consists primarily of a bar 50 pivoted ofi' center at 51 to a pin 52 which is connected to and carried by the fly wheel eccentrically of the hub thereof. The

bar 50 is provided with the weighted ends 53 and 54, the weight 53 normally as viewed in Fig. 4:, having its outer face nearer the rim of the fly wheel than the outer face of the weight 5 1, the coiled spring 55 which is connected to the bar 50 at 56 opposite to the pin 52 and to the fly wheel 57 normally holding the bar 50 and its weighted ends in such position. Disposed in the path of the outer weight to the inner face of the rim of the fly wheel is a fiat spring contact 58, which acts as a cushioning and retarding means when the bar 50 is in normal position. The rods 25 and 25 are connected at their lower ends at 59 to the respective bars 50, eccentrically of the shaft 2. The upper ends of the pitman rods 25 and 25 are pivotally connected with the inner ends of the arms 26 and 26 respectively and the said arms 26 and 26 are fixed to shafts 27 and 27 respectively which are journaled to standards 28 and 28 located at the top and to their respective sides to the casing 1. Arms 29 and 29 are fixed at their upper ends to the shafts 27 and 27 respectively and extend downwardly approximately at right angles to the arms 26 and 26. Bars 30 and 30 are pivotally connected at their outer ends to the lower ends of the arms 29 and 29 respectively and at their other ends the said bars 30 and 30 are pivotally connected with the links 14 and 1 1 respectively. Valves 31 and 31 are located to control the exhaust to the main exhaust pipe 7 and are operatively connected with the rods 32 and 32 respectively. A lever 33 is fulcrumed to the side of the casing 1 and its ends are connected with the upper ends of the rods 32 and 32. The lower end of a rod 34 is pivotally connected with the lever 33 at one side of the fulcrumed point of the latter and the upper end of the rod 34 is pivotally connected to the end of an arm 35 which in turn is rigidly fixed upon the shaft 16. By this arrangement a valve gear is provided which may be manually adjusted in connection with the pivoted links to cause one or the other of the valves to move to a greater or less extent over the ports that it governs and by reference to the drawings it will be seen that the parts are so positioned and arranged that when one valve is at a state of rest or approximately so over the port that it governs the other valve is movable over that port which it governs. This is for the reason that when the shaft 16 is turned by using the lever 18, the arms 22 and 22 are swung whereby the links 21 and 21 are moved longitudinally and the bars 12 and 12 are moved so that when one of the blocks 13 or 13 is at the lower end of a link the other block is at the upper end of its receiving link. Also when the shaft 16 is turned the arm 35 is moved about the axis of the said shaft whereby rods 35 are moved longitudinally and the lever 33 is rocked upon its fulcrum. The arrangement of the rods 32 and 32 with relation to the valves 9 and 9 is such that when for instance the rod 32 closes the valve 31 in its respective exhaust, the valve 9 is uncovered from its port or is permitted to move to uncovered position with relation to same while the valve 9 is held in covered position over its port 6. On the other hand when the valve 31 is closed the valve 9 is permitted to move over its port while the valve 9' is held in closed position over the port 6. By this arrangement the steam or fluid, pressure can pass through one side of the casing 1 while the valve at the other side of said casing is closed and vice versa. Therefore it will be seen that means is provided for reversing or changing the direction in which the engine shaft is rotated and to automatically operate the valves 9 and 9 from the fly wheel 3 through the governor bar 50.

Any form of impact receiving and pressure fluid expanding blades may be used upon the rotor R, the essential feature of the invention being an arrangement of the inlet and exhaust valve operating mechanism controlled automatically from the tlv wheels of the engine.
