ROTARY ENGINE Fi'led March 3. 1930 4 Sheets-Sheet 4 INVENTOR Y WITNESS liar-,3, E11/Wawy? ATTORNEY Patented Oct. 4, 1932 UNETE HARRY E. WILSEY, OF MIAMI, .ARIZONA ROTARY ENGINE Application filed March 3,

This invention relates to improvements in rotary engines of the type shown for example in U. S. Letters Patent No. 1,042,018 to Macoinbei, granted October 22, 1912, wherein a 5 plurality of parallel cylinders are arranged in concentric relation about a common axis and are mounted rigidly with respect toeach other and arranged to be revolved bodily around their common axis through recipro- 10 cation of their pistons, With the plane of rotation transverse te the longitudinal axes of the cylinders, rotation b ein g accomplished through a stroke plate to Which the ends of 1 piston connecting rods are ball jointed, which 5 stroke plate is arranged in a plane at an angle to the plane of cylinder rotation and for rotation about the axis of cylinder rotation, the angularity of the plate, permitting relative i'eciprocatory movement of the pistons in '20 their cylinders and presenting resistance causing the expansion of the fuel ignited behind the pistons to react against the cylinders and cause movement thereof in the line of less resistance constituted by rotation about said common axis. rlhe invention is designed to improve prior two-cycle engines of this type.

@ne feature of the invention consists in a Q0 cylinder 'and piston construction designed -to provide increased efficiency through permitting alcnger piston stroke, a more eiii'cient scavenging of exhaust gases, and the injection of a fuel charge into the combustion chamber of the cylinder Without the use of stroke-limiting fuel diverting baiiies on the heads of the pistons. Y

A second feature consists in the construction and mounting of the stroke plate and the connection of the piston rods thereto through provision of a continuous annular support for thestroke plate on a rigid axial support shaft, With the piston rods ball jointed to the stroke plate and guided for rectilinear movenient parallel With the axis of cylinder rotation.

A further feature improves the construction of the pistons themselves by providing a fuel charge by-pass traversing the piston and 7 9 having abaiii'e therein diverting the charge against heat hns on the interior of the piston 1930. semina. 432,919.

head, serving'the double. purpose of cooling the pistons and preheating the fuel mixture to increase its efhciencyl A As another feature, I have 4designed improved supporting means for the cylinder providing a common supportl for said cylinders mounted concentric to and revoluble with said cylinders about their axis of rotation, the cylinder supports involving annular supporting plates journaling on a fixed support shaft concentric with said axis. Additionally, I have mounted the cylinders, connecting rods and stroke plate on supports for axial rotatory movement as a unit with the pistons and connecting rods maintained for rectilinear movement in the longitudinal axis of the cylinders. With the connectingrods ball jointed to the angular stroke plate, their maintained rectilinear movement through the resistance offered by said vplate thereto, provides increased torques to the reactance force of the ignited charges.

These various features and other features of construction and design Will be more clearly apparent from the following'de'tailed speciiication` which is to be readf'in conjunction with the accompanying drawings forming part thereof and in Which Figure 1 is a. longitudinal vertical section through a rotary engine of the type described embodying the improvements of the present invention. j i Figure 2 is a similar section on an enlarged scale through the cylinder end of the assembly, vvit-h opposed cylinders and their 'pistons ,showing at the beginningA and end of' their power strokes, respectively.

Figure 7 is a transverse vertical section through the intake manifold taken on line 7 7 of Figure 1.

Figure 8 is a similar section, taken on line S- of Figure 1V through the connecting rod gui e.

Referring to the drawings by numerals, it will be seen, by reference to Fig. 1, that the hub of the motor is constituted by; affixed tubular rectilinear shaft 1 which is to be appropriately supported and which adjacent its outer or front end is provided with an internal closure plug 2 and at an 'intermediate point with a second plug 3 (Fig..2) partitioning offthe intervening.portion of the hollow shaft and forming a lubricant holding and distributing chamber 4.

Adj acentthe rear or inner'end, 4a third and cylindrical closure plug -(Fig. 2,) is` inserted, thespace enclosed betweeaplugsB-and 5 constituting #a fuel chamber 6.v lThese .last namedlplugsmay be-axially'bored and an oil pressure gaugeitube 7 Vmay. extend therethrough-and Voutwardlyfrom the rear end of shaft 1 *for connectiony to .anappropriate pressure gauge. Thetube-.atthe-front and rear ends of the plugs 3 and 4 is provided with suit-able packingglands to-prevent the entrance ofl-ubricantinto thefuel-chamber 6 and the escape offuelffrom said chamber.

`Adjacent and forwardly of the plug 5, the tubular -shaftlis provided'iwith a series of fuel intakefports 8. AA domed sleeve -9 overlies these ports and is held in position ony the shaft by end collared packing glands l10. The bottom. of the. domed sleeve 9 is .provided with a-fuel intake port 11 :andtheendflange 12A-off-arfuel`intake pipe 13 .is boltedto the bottom of sleeve-9 with its pipe communicating with said port. A suitable carburetor14 is attached to said pipe; v

Adjacent-and rearwardly of the closure or partitioning plug3,.the:fuel chamber section of the shaft is provided With groups of outlet slots 15 externally overlaidbyaa distributing ring 16ported'in alinement .with the slotslsand keyed tothe shaft. A duct 17 traversing the plug 3,. shaft 1. and` ring l16 conducts .lubricant `-from fchamber 4 to the outer face ofiring .16 whichf serves as a bearing foracooperating rotary sleeve valve hereinafter' described.

F orwardly of the. plug 3--and overlying the adjacent lubricant chamber 4 of the shaft, the inner-.race plate of. a roller bearing18 is fixed on the shaft. The hub 19 of an annular support plate 20 seats over the outer raceplate of .the lbearing and vis revolubly mounted thereon .for.rotationaboutithe shaft as an axis. The hub isprovided with a rearwardlyoffset flange21'fromwhich depending'an annular packing ring 22 lembracing the shaft andgprovidin-g an annular lubricant channel 23 between it and the roller bearing 18 into which lubricant is led from chamber 4 by a duct 24 in shaft 1.

Y A plurality of cylinders 25, of which only two are shown, have their outer or non-compression ends open, internally threaded and provided with peripheral abutment flanges 26. These' ends of the cylinders are inserted in bores of corresponding diameter in the support plate 20 adjacent its outer edge and are clamped thereto with their longitudinal axes in parallel with each other and with the shaft 1 by externally threaded end closure plates n27 having peripheral flanges 28 engaging the opposed face of the support plate 20.

Theseplates 27 are centrally bored to guide in the longitudinal axes of their cylinders the tubular connecting rods 29 threading into the bases of their pistons 30 and extending outwardly through the bores in the closure plates which are packed by glands 31 as shown.

rIhe cylinders 25 which, as shown, are of the externally finned air cooled type, are also rotatably supported adjacent their opposite orcompression ends by a second annular support plate .32 having an axial hub'33 housing and resting on the outer race of a roller bearing assembly 34' retained within the hub by an end bushing 35 threading. on the external periphery of shaft 1 and locked in position by abacking lock nut 36 likewise threaded on the shaft, the forward side of the hub has a depending annular packing flange 37 engagingthe shaft and the rear open side of the hub is closed by an annular packing plate 38. The inner faces of the roller bearing Vand bushing are grooved; the rear face of the bushingischanneled` and a lubricantl tube 39 extending through the-lock nut 36 provides means for vfeeding lubricant to the bearing as through the usual pressure gun. Between the hub flange 37 and the distributing ring 16,` a coiled spring 41 encircles shaft l and maintains the ring against its seat on the shaft.

The second support plate 32 is provided in alinement with the cylinders 25 with bores having rabbetted inner faces in which are fitted rabbetted peripheral anges 40 formed on the cylinders 25, the cylinders being thus supported by and rotating with plates 2O and 32 with theirf longitudinal axes in parallel with each other and .with shaft 1.

VForwardly or outwardly from the `roller bearing 18 of the first cylinder support plate 20, the shaft 1 is reduced in external diameter providing a shoulder 42. Seating against this shoulder at its rear or inner end and keyed to the shaft is a hub 43 (Fig. 1) having its peripheral face formed with a channel 44 therein extending in a plane inclined to the rightangular transverse plane of rotation of the support plates. 20 and 32 and their cylinders. The opposite sides of this channel are faced with side thrust bearings 45 and at the base of the channel a central groove 46 extending in a similarly inclined plane seats a circular ball bearing 47.

The inner circular edge of an annular stroke plate 48 engages and journals on the central roller bearing 47 with its adjacent side faces engaging the side thrust bearings 45, the stroke plate extending outwardly from hub 43 in an inclined plane alined with that of the channel 44 and itsvcentral base groove and confronting and lying in out* wardly spaced relation to the outer ends of cylinders 25 and their support plate 20. The inner end of hub 43 is held firmly against shoulder 42 by a clamping nut 49 threading on the shaft and backed by a lock nut 50, these two members serving to space the outer end of the hub from a lubricant pump casing hereinafter described. A lubricant duct 51 passing through shaft 1 and hub 43 conveys lubricant from shaft chamber 4 to the ball bearing 47, and other ducts 52 (Fig. 6) convey lubricant from groove 46 to the side,

thrust ball bearings 45. A spacing sleeve 53 extends between the rear or inner end of hub 43 to the axial roller bearing 18 of support plate 20 and is provided with a lubricant ej ecting opening therein alining with a lubri cant duct 54 in the shaft to spray lubricant upon the connecting rods 29.`

Outwardly of the hub 43 and spaced therefrom by the nuts 49,50, the hollow hub 55 of a lubricant pump casing encircles and is journaled on the reducedperiphery of shaft 1 and encloses therewithin a spiral gear ring 56 fixed on the shaftand lubricant entrance ducts 57 in the enclosed portion of the shaft. A tubular housing 58 integral with the hub 55 extends radially outward therefrom and has appropriately journaled therein a rotatable pump shaft 59 mounting a spiral gear 60 on its inner end meshing with the spiral gear ring 56. The tubular casing 58 at its outer end is laterally enlarged to house a toothed pump gear 61 meshing with a Second toothed' gear 62 fixed on the outer end of the shaft. The laterally enlarged portion of the casing is provided with a lubricant intake opening, the gears 61-62 functioning as the usual gear type pump to draw in and force lubricant through the tubular housing 58 to the hub 55.

The outer end of the tubular casing 58 is rigidly secured to the inner face of an annu lar housing plate or drum 63 whose inner or rear edge is bolted to the peripheral edge of the cylinder support plate 2O and whose outer or or front edge isy similarly bolted tol the peripheral edge of an annular drive plate 64 having an axial hub portion 65 journallin g on a roller bearing assembly 66 carried on a shaft sleeve 67 and retained within the hub by a washer plate which in turn is held thereagainst and spaced from they pump housing by spacing washers or nuts 69 threaded externally on the shaft 1 and engaging the pump casing hub 55 at the side'opposite to the spacing nuts 49, 50. The hub 65 has its outer face formed with a packing flange 70 guides into frictional tightly clamped seating engagement in the drive plate. The tubular guides extend in alinement with the longitudinal axes of the cylinders 25 and are open at their inner or rear ends to receive the outer ends of the tubular connecting rods 29 which are provided with external peripheral ribs 29a (Fig. 8) seating in the grooves 73 of the guides.

The tubular connecting rods pass through i circular openings or sockets 77 in the stroke plate 48 faced by bushing rings 78 and are enlarged to provide spherical-enlargements 79 of a diameter to seat in these openings and provide universal ball joint connections with the stroke plate in the line of theircylinder axes. AThe ball joints or spherical enlargements 79 are retained in the stroke plate sockets by annular cross head plates 80 embracing opposite sides of the stroke plate and having concaved inner faces conforming to and engaging the spherical faces of the ball joint spheres 79. f

The housing 63 encloses therewithin between the drive plate 64 and support plate 20, the lubricant chamber portion of the shaft,

the stroke plate and its hub, the gear pump housing, the tubular guides and the connecting rods. It constitutes also a rigid connection between the drive plate and the cylinder supporting plate 2O and forms a lubricant is.

reservoir. rlhe outer end of the pump casing is fixed to the housing drum 68 and rotates therewith, the gear 60 on the inner end of the pump shaft riding over the fixed spiral gear 56 on shaft 1 and rotating the pump f shaft to cause its gears 61-62 to draw oil or other lubricant down into the tubular case 58 and to the hub 55 from whence it passes through the shaft ducts into the lubricant chamber 4 and is distributed as described.' It will be noted that the inner or rear face of th-e drive plate roller bearing assembly 66 is exposed on the interior of the housing 68 and is directly lubricated. Since the lubricant is thrown to the outer side of the hous-v ing by centrifugal action in the rotation of the housing about the shaft, the pump gears 61-62 will always feed lubricant while the engine is in operation.

The cylinders 25 and pistons 30 are of par-l ISD ticularly advantageous construction'and have peculiar combinative interrelation. While 'I have shown only two cylinders in diametrically opposed relation, it will be obvious that this number may be increased as desired and as consistent with the size of the motor and that the stroke plate and connecting rod connectionsand gui-ding means will be duplicatively increased accordingly, aswell as cylinder and piston arrangement and mounting.

The engine herein involvedis oft-he two cycle type andthe cylinder and piston constructed ofthe present invention is designed to provide increased efficiency through provisions for longer stroke, more complete scavenging, cooling of the piston head and preheating of the fuel passing to the combustion chamber of the cylinders.

Accordingly, the outer or noncompression ends of the cylinders 25 at their sides adjacent shaft 1 and outwardly of the distributing sleeve 16 are formcdwith longitudinally extending peripheral enlargements 81 providing for internal longitudinally extending fuel receiving passages 82 having their opposite ends ported into lcommunication with the interior of the cylinder. Fuel tubes 83 threaded into the enlargements 81 intermediate of their ends extend-inwardly therefrom and seat in bores in a valve sleeve 84 closely fitting over and revolving onthe fuely distributing ring 16 on shaft 1 and are held in the sleeve bores-by packing glands 85 backed by nuts 86 threaded on the tubes 83. As shown (Fig. 2) the valve sleeve 84 is provided with opposed ffuelintake openings with which the tubes 83 communicate. As thissleeve rotates with the cylinders, support and drive plates, etc., about shaft 1 as an axis the group as for example where two cylinders only are used), or groups of ports 15 will register successively with successive tubes 83 in the cycle of rota-tion, the registration period being, obviously,l timed tothe rearward movement of the pistons on their compression stroke to draw a charge of fuel into the outer noncompression end of the cylinder, this Vcharge being forced by the piston on its succeeding firing stroke through by-passes to the compression end of the cylinder for compression and firing on the next succeeding compression stroke. i

This is accomplished by providing the cylinder walls at the sides opposed t o the receiving passages 82 with similar longitudinally extending peripheral enlargements 87 providing for longitudinal internal fuel jet passages 88 ported at their opposite ends into communication with the interior of thev cylinder. The passage 88 constitutes, at the sides of the cylinder opposite thereto, a. prolongation of the receiving passage 82 in the direction ofthe compression end of the cylinder, with the intake or outermost end port 88a opposed to the innermost or discharge port mediate the opposed passages 82 and 88 are provided with exhaust ports 89 therein. l/Vith the exhaust ports so located with reference to the fuel jet ports and the latter inclined toward the compression end of the cyl- Y inder, I am enabled to dispense with the usual jet diverting baflie plate on the exterior of the cylinder head and thus permit further inward or compression movement of the piston and a longer stroke thereof. Furthermore the location of the exhaust ports with reference to the fuel jet ports, enables, in a two cycle engine, a more complete scavenging of the exhaust and maximum power from the explosion since these exhaust ports will not be opened until close to the end of the power stroke when the gases have reached their fullest possible expansion.

The fuel received in the passage 82 on the compression strokeof the piston is forced by the piston on its power stroke through the passage to its discharge port 82?) and is permitted by the piston, at the time of maximum pressure on the fuel toby-pass through the interior of the piston under substantial pressure to enter the intake port 88a of the fuel jet passage for discharge therefrom as a jet irecte'd to the compression end of the cylin- This result, accompanied by cooling of the piston head and preheating of the by-passing fuel, is accomplished advantageously by the piston construction as shown in Fig. 2 in which the pistons 80 are of hollow construction with internally threaded sockets 90 in their outer ends to receive the threaded ends of the connecting rods 29. Adjacent the head ofthe piston a conical partition 91 forms with the adjacent interior surface of the piston head a'transverse passage or fuel by-pass 92 across through the interior of the piston. The side walls of thepiston at the opposite ends of the passage 92 are formed with ports 93 which, at the end of the power stroke of a piston (as shown in Figs. 1 and 2) alines with and cross connects the discharge port 826 of the fuel receiving passage and the intake port 88a of the fuel jet passage. The conical partition 91 acts as a baille or deflector and directs the by-passing fuel against the inner face of the piston head or end, which may have one or more heat radiating fins 94 formed thereon. The head of the piston is thus continuously cooled by the by-passing fuel which, by absorption of the fin radiated heat,vis preheated before entering the combustion chamber, with obvious resultant advantage. With the exhaust ports positioned to be opened by the piston at and slightly prior to the completion of its power stroke (as seen in Fig. 2), they are located at the natural head of expansion of burning gases iov and not only is maximum permissible expansion thereof secured prior to exhausting but the exhaust occurs at that point to which the expanding gases normally flow and increased scavenging is therefore secured as compared to previous location of the exhaust and intake ports in substantial opposition with an intervening piston baille deflecting the incoming fuel.

Since the operation of the type of internal combustion engine involved herein is Well known, the preceding detailed description of the structure and function of the specific mechanism of the present invention renders recapitulation of its operation unnecessary.

The specific form of the invention described herein While representing a preferable embodiment of the inventive idea, is intended as illustrative rather than restrictive and is subject to modification in form and arrangement to suit different conditions of manufacture and use in consonance with the spirit of the invention and the scope of the appended claims.
