No. 851,195. Patented. April 23, 1907.

To all whom it may concern:

1 Be it known that we, ALBERT L. BAUER and RAYMUND BAUER, citizens of the United Fig. 7 illustrates a slight modification of the i abutment.

' Similar numerals of reference are employed States, residing at Wheeling, in the county of to indicate corresponding dparts throughout .Ohio and State of West Virginia, have inthe several figures of the r vented a new and useful Engine, of which the i awings. In carrying out the invention, two engines following is a specification. i of similar construction are connected to a This invention relates to rotary engines, main shaft 10, and the engines operated in and has for its principal object to provide a 1 consecutive order, one eliecting a half revonovel form of engine in which a cylinder is lutlon of the shaft, whlle the other efiects the second half revolution, so that both pistons may make the complete rotation.

The cylinder 11 of each engine is circular in form, and within said cylinder is a circular piston drum 12, rigidly secured to the shaft lOand carrying a radially disposed piston wing 13, Which 'travels in the annular space between the periphery of the piston drum and the inner circular wall of the cylinder. Arranged above, and in communicationwith part displaced by the action of-a fluid under pressure, or by the formation or combustion of a gas or other compound, the water serving to transmit movement to the revoluble piston and preventing direct contact between the piston and the actuating fluid.

A further object of the-invention is to provide a rotary engine in which the force or pressure of the fluid actuating medium is transmitted to the piston through the medium of a liquid.

A still further obj ect of the invention is to provide a novel form of rotary engine in which the cylinder is arranged in communication yvith a pair of chambers, either of which may serve as the compression cham: ber, while the other receives a volume of liquid equal to that displaced by the action of thefluid.

With these and other objects in view, as

of vertically disposed casings -15 and 16, and between these casings is a movable abutment 17. This abutment may be moved to such position asto permit the free passage of the piston wing 13 as the piston drum 12 rotates.

'The cylinder and the chambers 15 and 16 are filled with water or other fluid up to the level indicated in Fig. 1, and where steam or similar fluid is to be employed as the working in each of the cham em 15 and 16, t e piston serving to prevent direct contact between the steam and the Water, thus avoiding unnecessary condensation. P p

The cubic content of each of the chambers 15 and 16 is approximately equal to the cubic content of the annular space between the piston drum and the inner clrcular Wall of the cylinder, and when .the steam or other fluid is operating in one of said chambers, the li uid displaced by the action ofthe steam will rise in the other chamber.

At a short distance above the normal level tion consists in certain nove features-of construction and arrangement of parts, hereinafter fully described, illustrated in the pointe out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure. may be made without departing vantages o the invention. I

In the accompanying. drawings :Figure 1 structed in accordance with the invention. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is aplan view of the engine, parts being broken away to more clearly illustrate the abutment connectionsj Fig. 4 is a sectional plan view through' the lane of the adjustable valve or abutment o the expan- 1 sion chambers. Fig. 5 is a sectional plan view through one of the valves for control valve or abutment 22 which ma be moved across one or other of the cham ers 15 and sion or pressure space, the opposite wal being formed by one of the floating istons, and when this slidable valve 'or a utment is fluid. Fig. 6 is a view similar to Fig. 1, illustrating a slight modification of the invention.

is displaced.

The adjacent Walls of the two cylinders are 16 in order to form one wall of anex an the upper portion of the cylinder 11 is a pair -medium, a floating iston 19is arran ed'withof the floating piston, 19 is arranged a slidable moved across one of the chambers, it leaves the other chamber wholly clear, 'so that the floating piston may freely rise as the water or abutment 22, which will occur at-a timewhen the abutment 17 is down in engage ment with .the peripheryof the piston 12 and the piston '13 has moved to about the position shown in Fig. 1, the ressure and ex ansive force of the steam will depress the oat' ing piston 19, and this movement will be transmitted through the water or other liquid, compelling the piston wing to move in the direction indicated by the arrow and the liquid ahead of the piston wing will be forced to moveupward into the chamber 16.

The volume of liquid\ normally contained within the chamber 15 is slightly greater than half the volume of fluid'in the'annular space between the piston drum and cylinder,

so that by the time the floating piston 19 has completed its stroke, the iston drum will have made a'one-half revo ution, and practically all of the water will be displaced from chamber. 15, while the chamber 16 will be nearly full. At this stage of the operation, the second engineof the shaft 10 will operate, the piston 13' of the second engine being at a' point diametrically op osite the piston 13 of the first engine, and t s second engine will compelthe second half revolution of bothpistons. is admitted to the second engine, the abut+ ment 17 of the first engine is moved from the annular space surrounding the piston and the exhaust valve below the valve or abutment 22 is open, so that the liquid'in the two chambers 15 and 16 may assume a common,

level, and this levelwill have been attained vbythe time the piston wing 13 a ain reaches the position shown in Fig. 1, and

is in readiness to commence a second, stroke, or second rotation. v

The abutment 17 is preferably formed of two segmental plates 28 that are pivoted on shafts 29 and 30, these shafts being providedv with reduced end portions havingintermeshing gears 31 to insure simultaneous movement of the abutment members to open and closed position. of the abutment members are arranged to fit against the correspondingly concaved surface of the piston drum 12, and when in 1 closed positionthe abutment is sufliciently' tight to prevent the leakage of the li uid from one side of the cylinder to the ot ier. One of the shafts, 29 .-is providedwith a Immediately after the steam gear with its pin 42.

The curved outer ends rocker arm 33, which is connected to one end of a lever '34 that is pivoted on a bracket 35 carried by the frame, and this lever 34 is pivoted at a point intermediate of its ends to a vertically movable bar 37 thatis'und'er the controlof a cam- 38 carried by the main shaft.

When the actuating fluid is not-ofsuc'n-n'a ture asto rapidly condense when brought into contact with liquid, the floating pistons 19 may be dispensed with and the fluid allowed. to operate directly against the water or other liquid. For this purpose compressed air or an explosive compound may be employed, and the upper ends of the chambers. 15 and 16' may be laced in-communication with each other, t us ermitting the employment of chambers of ess height than where the:floating pistons are used. The liquid displaced from the lower portion of one chamber is. then free to flow'upward into the second chamber, while the space above the valve or abutment in the first chamber serves toreceive the air above the fluid, which air being placed under slight pressure, will tend to assist in restoring the normal level of the water after the abutments 17 have been moved to open position. i

In some, cases the abutment may be formed of a single. plate 17 and'in this case provision must be made for a greater range of movement of the abutment, than where in the preferred construction.

The valves 26 are provided with stems 40 from which extend hooks 41 that engage ins 42 carried by the bell crank levers 43. he bel crank levers are pivoted to brackets 44, projecting from the'fiame of "the engine, and said bell crank levers are connected by rods 45 to eccentrics 46 on the main ,shaft.

To provide for the reversal of the engine, a shaft 47 is carried by the brackets 44 and to said shaft is secured a pair of cams 48, and the cams of eachpair or 'set are disposed at a right angle to each other. Atthe end of-the shaft is an operating lever 50 which may be turned for the lpurpose ofthrowing one hook out of gear wit the pin 42, while the hook of the mating valve is allowed to drop into This aflords a central means for disconnecting the valves of .those oint above the liquid level, whereby the iquid in said chamber is displaced and the movement transmitted to the piston wing.

2. In a rotary engine, the combination with a cylinder, of a pair of liquid containing chambers in communication therewith, a revoluble' iston drum, a piston wing extending there rom, an abutment movable into and out of the path of the piston wing to per mit communication between said chambers, means for controlling the admission and exhaust of an operating fluid to one or other of the chambers at .a oint above the liquid level, whereby the liquid may be displaced from one chamber and rise in the other, and

' transmit movement to the piston wing.

' 3. I The combination ina rotary engine, of a cylinder, a pair of vertically disposed liquid containing chambers in communication therewith,.a-mo vablevalve or abutment adjustable across either of the chambers and forming the fixed wall of a pressure space, a valve controlling the admission and exhaust of fluid under pressure to this pressure space, a piston drum, a wing projecting therefrom;

an abutment, and means for moving the abutment into and out of engagement with said piston drum. i

4. The combination in a rotary engine, of a cylinder, a pair of vertically disposed liquid containing chambers in communication therewith, float istons arranged within the charmbers, a sli able valve or abutment movable across either of the chambers to form one wall of a pressure space, a valve for controlling the admission and exhaust of a working fluid to the pressure space, a piston drum in' the cylinder, a piston wing carried by the drum, an abutment, and means for actuating the abutment.

5. In a rotary engine, the combination with a shaft, of a pair of cylinders surrounding the same, a air of piston drums secured to the shaft and aving piston wings, the wing of one drumbeing diametrically opposite the wing of the other drum, a air of iquid containing chambers connecte to each cylinder, means for introducing a fluid under ressure to one chamber of each pair to disp ace the liquid therein, the operations alternating in the respective chambers, and abutments movable into and from the cylinders to permit communication between the liquid containing chambers ofeach pair.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
