App1ication filed May 11, 1912. Serial No. 696,684.
To all whom it may concern:
Be it known that I, HENRY HERMANNS, a citizen of the United States, residing at Cross Roads, in the county of Charles and State of Maryland, have invented a new and useful Rotary Engine, of which the following is a specification.
The present invention relates to improvements in rotary engines, the primary object of the invention being the provision of a balance reversible rotary engine, in which a plurality of intake and exhaust valves are oscillated in time through the medium of the rotor, a novel mechanism being provided for regulating the registration of the ports of the respective valves to conduct the pressure fluid to the rotor chamber to regulate the speed at which the rotor is operated and also the direction of rotation.
A further object of the present invention is the provision of a novel form of cam actuated mechanism for imparting simultaneous oscillation to all of the respective valves of the engine, so that the pressure fluid will be properly conducted at substantially diametrically opposite points within the rotor chamber, the rotor being provided further with rigid abutments, while the stator is provided with diametrically opposite slidable partitions disposed to be projected and retracted relatively to the rotor, a plurality of cams being carried by the rotor and operably connected to the valve operating and the partition operating mechanisms to actuate the valves and such partitions in consonance with the rotation of the rotor.
With 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 the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawingsFigure 1 is an end elevation of the complete rotary engine taken from the valve and partition actuating side thereof. Fig. 2 is a top plan view of the complete rotary engine, sections being taken on lines 2*2 and 22 of Fig. 1 to show the construction of valve and partition controlling means. Fig. 3 is a longitudinal sectional view through the complete rotary englne. Fig. 4 is a section taken on line H of Fig. 1. Figs. 5 and 6 are detail views of the two cams and their reciprocatory frames. Fig. 7 is a vertical section through the two superposed valves at the outlets thereof and also a portion of the casing adjacent thereto.
Referring to the drawings, the numeral 1 designates the stator or main casing which is provided with the diametrically oppositely projecting portions 2 and 2' respectlvely, terminating in the feet or supporting portions 3 and 3, respectively. The rotor casing 1 is open at both ends and is therefore properly sealed by means of the plates or heads 4: and 4 respectively.
Disposed concentrically of the casing 1 is a shaft 5, one end of which is journaled in the stufling box 6 carried by the head 4, while the other end carries the inner cam 7 internally of the head 4, and which is surrounded by the stuiiing gland or ring 6. Keyed upon and rotatable with the shaft 5 beyond the cam 7, is another cam 8, said cam 7 being provided with the cam recess 7, while the cam 8 is provided with the cam recess 8, the purposes of which will presently appear.
Keyed upon and rotatable with theshaft 5 is the cylindrical and hollow rotor 9 provided with the diametrically opposed transverse slots 10 and 10 for the detachable reception of the pistons or stationary abutments 11 and 11, both of which are constructed similarly and are provided with the outer periphery engaging surfaces 12 and 12 and the two oppositely inclined surfaces 13 and 13 respectively. The bolts Z) are employed to retain the respective pistons or abutments 1111 in the proper relation to the rotor 9 and when the rotor is assembled, the casing 1 is divided into the two fluid pressure receiving chambers CC, respectively.
As clearly shown in Fig. 3, the abutments 2 and 2 are provided respectively with the transverse cylindrical bores 1415 and 14L and 15 and in each of the respective bores is removably mounted a bushing 16 which is of substantially the full length of the bore, as clearly illustrated in Fig. 2. Mounted for oscillation in each of the respective bushings 16, is a hollow fluid-pressure induction valve 18 and an exhaust valve 27, bot-h of which are connected together for oscillation in unison through the medium of the pinand-socket-connection 28, as clearly shown in Fig. 2.
In order to actuate both of the valves 18 and 27 simultaneously, the spider 19 carried in the inlet end of the fluid induction valve 18, is provided with the concentric boss 20, all of which as clearly shown in Fig. 1, project exteriorly of the head plate 1 of the engine and have connected thereto, the respective crank arms 21, 21, 21 and 21 the crank arms 21-21 and 2121 being disposed in pairs for simultaneous and cooperative action. The two cranks 2121' are coupled together by means of the rods 22, while the two crank arms 21 21 are coupled together by means of the rod 22, the operation of which will be described later on.
Each. fluid induction valve 18 is provided with the induction port 23 which at the proper time is disposed to be placed in registration with the induction port 24 of the casing 1, there being four of such ports, while the exhaust valves 27 are each provided with an exhaust port 26, which at the proper time is disposed to be placed in registration with the exhaust port 25 of the casing 1. The respective ports 23 and 25 are disposed in alinement, side-by-side, in proper relation to the respective valves 18 and 27, but as the respective ports 26 of the valves 18 and 27 are out of alinement with each other, it is impossible for the intake and exhaust ports of the two coupling valves to register with their respective cas ings ports simultaneously.
Each of the exhaust valves 27 are provided at their outlet ends with the spiders 30, which permit of the proper exhaust of the pressure fluid therethrough and out of the head 4 of the engine, each spider being provided with the boss 31. concentrically thereof for the reception of the adjusting screw 31' mounted in the stationary spider 32 carried by the head 41, the said screw 31 being provided to properly adjust the valves 18 and 27 within the bushings 16 and thus properly retain the same and allow for any wear due to the friction between the valves and such bushings.
This particular engine is constructed to be used as a unit, or in a series, and when connected in series, an exhaust conduit E is connected to receive the exhaust from the respective valves 27 and convey them to the intake valves of the next succeeding engine.
In order to actuate the respective valves in consonance with the rotor 9, to control the introduction of the pressure fluid and the quantity thereof, a walking beam 3 1 has its journaling shaft 35 mounted in the pillow block 36 supported by the top of the casing 1, while the outer ends thereof are pivotally connected to the upper ends of the respective rods 22 and 22. By this means the arms 21-21 and 21 and 21, have imparted thereto an equi-distant movement, but in order to regulate the throw of the respective valves, so that the respective intake and exhaust ports are moved into greater or less registration with the respective intake and exhaust ports of the casing 1, thus con trolling the direction of flow of the pressure fluid and the quantity admitted to the chambers C and C respectively, a manually con trolled lever 37 is pivoted to the outer end of the shaft 35 and has its lower end 38 connected to the inner pivotal end of the oppositely extending arms 39-39. Each of these respective arms 3939 is provided with its respective slots 10- 10, for the sliding reception of the respective pins 4:1 11 of the toggle joints 4-2 and 42 respectively. The upper ends of the respective toggle joints 424l2 are pivotally connected to the terminals of the walking beam 34- intermediate of the ends thereof, while the lower ends are pivotally connected to the ends of the respective lugs 43- 13 carried by the reciprocatory frame 1%. This frame 44 is mounted exteriorly of the head 4 and is provided with the oppositely extending guide arms 45%5, which are mounted for sliding movement within the removable guides 46- 16 which are connected to the outer face of the head 4, as clearly shown in Figs. 1 and 41. Y
A pin 47 carrying a roller 48 is carried by the frame 4 1, such pin and roller being projected into the cam recess 8 of the cam 8, so that the rotation of, the rotor 9 and shaftb will impart rotation to the cam 8 and through the recesses S and the pin 17" impart a reciprocatory movement to the frame 4 1 and thus through either toggle joint 42 or 42 will oscillate the walking beam 34 and consequently operate all of the valves of the engine.
Disposed to the rear of the frame 14 and for reciprocatory movement individually thereof, is a frame 48 providedwith the oppositely extending arms 1-94t9 and as before. stated mounted to the rear of the arms 45%5 within the respective guides 16- 16. The frame48 is provided with the stud or pin 50 which projects inwardly and has its roller 50 disposed within the cam recess 7 of the cam' 7, so that the rotation of the shaft 5 and the cam 7 through the stud. 50 will impart the necessary reciprocatory action to the frame 4.8.
.The frame 41-8 is provided with the lugs 5151 to which are pivotally connected theshort links 52-52 respectively, and to these links are connected the inner terminals of the respective bell-crank levers 53 53. which are journaled to the heads of the engine and disposed in opposite actuating position, as clearly shown in Fig. 1. The upper terminals of the respective bell-crank levers 53 53 are connected by means of the oppositely extending rods 54 -54E, to the crank arms 5555 respectively, of the rock shafts 5656 which are properly journaled upon the upper surfac'eof the respective feet 3 and 3 of the casing.
Each shaft 5656' has extending therefrom, a pair of arms 57 and through the medium of the short links 58 and the bolts or pins 59, which pass through the stufling boxes 60 connected to the abutments 2 and 2 respectively of the casing 1 at diametrically opposite points, will properly actuate the slidable partition or abutting walls 616l mounted centrally of the respective abutments 2 and 2 to thus divide the space between the inner wall of the casing 1 and the outer peripheral surface of the rotor 9 into the respective chambers CC. Upon the inner ends of the respective partitions 6161 are provided the stufling strips a which provide a yielding contact between the respective partitions and the periphery of the rotor 9 and at the same time prevent any leakage of the pressure fluid at such point. i
As clearly shown in Fig. at, the circular packing ring 62 is mounted in the inner face of the head 4 and is held resiliently toward the end of the rotor 9 by means of a plurality of springs 63 which are disposed in cupshaped abutments 641 formed integral with the head 4. By this means a tight joint is provided near the periphery of the rotor to prevent the escape of the pressure fluid to the space above and around the head at this point. By means of the packing gland 6, as also shown in Fig. 4, a tight join't at the periphery of the cam 7 between the surrounding portion of the head 4 and also the abutting end of the rotor 9 is provided, thus doubly insuring against the leakage of pressure fluid at this point.
From the foregoing description taken in connection with the drawings, the operation of the present invention is readily understood, but briefly stated it is as follows The pressure fluid is admitted through both of the conduits or pipes 6565' and into the respective inlet ends of the upper two intake valves 18 and through the conduits 6666 respectively, to the lower two intake valves 18, thus providing a means for supplying the pressure fluid to the interior of all four of the valves 18. The lever 37 is now moved, as for instance to the position as shown in Fig. 1, so as to shorten the toggle 12 and make it idle, and permitting the toggle 42' to be extended practically its full length. The shortening of the toggle 42 thus decreases the distance between the arm 43 and terminals of the walking beam 34 connected to the valve actuating rod 22,
thus providing a means whereby as the cam 8 is rotated, and the frame 44 is consequently reciprocated, the walking beam 34 will be oscillated solely by the toggle 49., retaining the arms 2121 and 21*21 at the same respective angles to each other, the position of the respective arms 2121 and 21 21 controlling the position of their respective valves, so that the intake ports 23 and the exhaust ports 26 of the exhaust valves 27 are advanced in the valves controlled by the rod 22 so that the intake ports 23 of the diametrically opposed valves 18, will be placed simultaneously into registration with the intake ports 2% of the respective chambers C and C and thus impartrotation to the rotor 9 in the direction of the arrow Fig. 3.
By means of the reciprocatoiy frame 48 and the cam 7, said frame 18 is reciprocated and through the bell crank levers 5353, as the respective pistons 11 and 11 have passed the respective exhaust ports 25 disposed at diametrically opposite sides of the casing 1, one to each chamber C C, the slidable partitions 61-61 will be actuated to be retracted within the respective abutments 22 and thus permit the pistons 1111 to pass the said partitions, the cam 7 being so constructed that the instant the outer surface 12-12 of the respective pistons has passed beyond the inner ends of the partitions 6161, the said partitions will be projected inwardly and into engagement with the periphery of the rotor 9 in time to provide the proper pockets for the pressure fluid between the partitions and the intake 24 of each chamber. By this means the pressure fluid is admitted at diametri cally opposite points to the rotor chamber and the rotor has imparted thereto, the consequent desired rotation, and that the respective toggles 1:242 may be adjusted at various angles with relation to each other, thus regulating the position of the respective arms 2121 and 21-21", and consequently the desired projection of the pres sure fluid within the respective chambers and also the quantity, so that the speed and direction of rotation of the rotor 9 is controlled directly through the lever 37.
When it is desired to reverse the rotation of the rotor 9 and cause the same to rotate in the opposite direction to the arrow in Fig. 8, the lever 37 is moved to the right as viewed in Fig. 1, to cause the lengthening of the toggle 42 and the folding of the toggle 12.
hen the rotor is rotating in the direction of the arrow in Fig. 3, the respective bores 15 and 15 are the steam induction port-ions of the engine, while the respective bores 14 and 14: are the exhaust portions of the engine, the reversal of the lever 37 reversing the respective valves in the bores of the engine, so that when the lever 37 is thrown to the right and the toggle 42 is folded and the toggle 42 is straight, the bores 1414 will be converted into the induction portion of the engine, while the bores l515 will be the exhaust portion.
