ROTARY ENGINE.

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed October 15.1906. Serial No, 339,108.

To all whom it may concern:

Be it known that I, HOMER ARTHUR KING, a citizen of the United States, residing at Colton, in the county of San Bernardinoand State of California, have invented a new and useful Automatic Rotary Engine, of which the following is a specification.

My invention relates to improvements in motive-fluid in said chest shall be equal on the edge or edges of the revolving valve or valves instead of on one side, one motivefluid chest serving two engines, imparting power to each alternately and by expansion giving continuous pressure on two or more piston headsysecond, to construct the reversers or regulators so as to admit the insertion of oil pipes; third, to provide mechanism for working the oscillating cylinderheads automatically from and close to the revolving shaft, with a casing inclosing all of the mechanism except the sprocket wheel on the shaft and the crank that reverses the engine; fourth, to prevent the escape of motive-fluid by inserts or packings on either or both below and above the motive-fluid chest, and on each side of the piston disk, near the periphery, resting against springs; fifth, to further prevent escape of motive-fluid from the annular cylinder, when its construction is rectangular in cross-section, by employ-,

ing rectangular collar rings with overlapping halved joints, resting against springs; sixth, when the power is secured by the explosion of the motive-fluid, to provide chambers in the annular cylinder between each piston head and closed cylinder-head, the explosion being effected by means of a battery or lamp as soon as the chambers are filled with con 1 densed motive-fluid. I attain these objects by mechanism illustrated in the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a cross section showing the union of two engines, Fig. 2 is a view of one united; Fig. 4 is a cross sectional view of two engines united showing the rectangular form of the annular cylinders; Fig. 5 is an elevation of the reverser with oil pipe; F ig. 6 is an elevation of the regulator, two being used when two engines are united; Fig. 7 is an elevation of the revolving valve, preferably two being used and when two engines are united a little space being left between them to prevent too much friction, the two being united by the packing disk K and both secured to the disk by projections into slots permitting each valve to be gently pressed against its companion regulator L by the motive-fluid, and by a few coiled springs which may assist in pressing the valves apart; Fig. 8 shows packing ring K, although this ring may not be necessary; Fig. 9 is an elevation of disks C with piston heads E E bolted thereto; Fig. 10 is a section of Figs. 1 and 4 taken on line i t of Fig. 1, showing the oscillating cylinder-heads FF turned down after piston heads E E have just passed; Fig. 1] is a cross section of a portion of the disk C shown in Figs. 9 and 10, taken on line it u of Fig. 9, and showing only one of the spliced collar rings V of a piston head with springs and packing rings K pressed outward by springs X; Fig. 12 is one of the disk rings K Fig. 13 is portion of Fig. 4 but without reversers L L and regulators L L and Fig. 14 is an elevation of one side of Fig. 13, showing rods Z, Z, instead of the belt and chain connection shown in Figs. 2 and 3; and showing also buffers Z Z arranged to strike rubber or air cushions Z Z causing cylinder-heads F F, to gently cease oscillating just at the right time.

A and B are the main parts of the annular cylinder which may be formed circular with a milling machine and united as in Figs. 1, 2, and 3, or may be formed by a lathe taking a rectangular piston-head like Fig. 11 and united around the periphery like Figs. 4 and 10.

B is one of the round removable portions of the annular cylinder furnishing access to a the oscillating cylinder-heads F, and A is the corresponding removable portion for the other cylinder-head of the annular cylinder shown in Figs. 1, 2, and 3.

C is the piston head disk, there. being two in each of the two double engines shown in this application.

D is the revolving shaft, D is one of the sprocket-wheels and D one of the two-armed for cylinders such as illustrated in Figs..1,"2,""

cam devices for actuating the pulleysystemcontrolling the movement of the cylinder heads.

E is one of the piston-heads wider at the base to economize motive-fluid, and is bolted to the disk C which is splined to the shaft D.

F is one of the oscillating cylinder-heads,

its periphery being circular in cross section and 3, but straight for those of rectangular form like Figs. 4 and 10.

F F are buffers for the oscillating cylinder-heads, preferably air cushions, moved 90 degrees when actuated by the, re versers L L G is the cover for the pulley system actuating the cylinder-heads and may be easily removed.

H is an exhaust: I I are inlet ports for the motive-fluid when the engine is running forward, and I I are inlet ports for running backward as shown in Fig. 10. Chambers M M are for the motive-fluid and are made much larger when the power is obtained from the explosion of motive-fluid, the chambers M M being filled with compressed motivefluid and I I or I I closed by the regulator and revolving valve while piston-head E is passing the cylinder-head F.

J is a chain, belt, or flexible connection secured to or passing one or more times around pulleys J J, J 2 and J 3 and operates cylinderheads F F from close to the shaft by timely contact of the points or lugs of cams D against the small wheels J 4 J or J 5 J 6 constituting operating pins or studs for one of the two united engines, these being operated on one engine while the other engine is running by expansion. Other forms and arrangements of cam and wheels or other methods of operating the cylinder-heads might be used. The two lugs, on cams D in revolving move studs J and J thus moving pulleys J 2 and J just enough in opposite directions to open and close the passage under two oscillating cylinder-heads by means of sprocket chain J and pulleys J J to let piston-heads E E pass. hen the reversers L L are moved to reverse the engine, the connections S S shift the chain J, pulleys J J and J 2 J and bring studs J and J 7 in position to contact with cams on D instead of pins J J thus oscillating the cylinder-heads F F as before, but the piston-heads E E will then be moving the engine in the reverse direc- 131011.

K is a packing-ring between the parts of the engine casing.

K are packing-rings in the side or edge of the piston head disk C which are pressed outward by the coiled springs.

as are bent flat springs on the periphery of the valves L, serving to spread them apart.

A motive fluid chest or opening I is formed between the periphery o the revolvand I are l t ing valves L L and the peripheral walls of the annular cylinder. Valves L L move with the supporting disk K, being prevented from turning thereon by set-screw stays N, the nuts thereon serving also to adjust the position of the valves. The valves-L L are free to be forced apart by the motive-fluid and are also kept close to the regulators L by means of coiled springs seated in shallow holes P P in the sides of the valves. The position of the reversers L is changed, for the purpose of reversing the engine, by means of hecrank levers L and this movement also changes the position of the buffers F F correspondingly, as the buffers are connected to the reversers by means of springs S S.

In case the motive-fluid is used explosively, lamps or batteries are placed in cavities M M, which serve to explode the motivefluid in the chambers M M, as they pass the channels or openings leading to said cavities M M, the openings being closed so quickly that the light in the protected lamps is not extinguished.

Oil is conveyed to the bearings on the shaft D, through the tubes 0. The usual circular collar rings are used on piston heads in Fig. 1 but in the construction shown in Figs. 4, 9, 10, 11, and 13, the collar rings U are rectangular, spliced or lapped at V V and are pressed outward by springs IV. X is a coiled spring'pressing the packing rings K K against the sides of the annular cylinder.

In Fig. 13, I have shown the engine without using the regulator L and the reverser L 4 A removable part of the casing Y, affords easy access to the valve L, which may be adjusted by me ans of the block and set-screw N when, however, the regulator L and reverser L are used, openings ma be provided each side of the packing-ring I to give access to a set-screw on the eriphery of the valve, while the opening to ac mit motive-fluid to the chest I may be provided on either side of the packing-ring.

The general operation of my engine is as follows: Upon admitting the motive-fluid at high pressure into the chest I, the fluid enters through inlets I I as shown in Fig. 10, into the chambers M M in cylinder-heads F F, and propels piston-heads E E in the direction of the arrow, at first by direct pressure which is then cut off by the revolving valve L, the pistons E E then continuing under the expansion of the motive-fluid: Before exhausts H II are reached, however, the motive-fluid enters the other engine at two points, and thus continuous pressure is had on two or more piston-heads, avoiding dead points, and

. very long stroke is secured and the exausth occurs only before the piston-heads reach the l rising cylinder heads; with the reverser and regulator on each side of the valves L L the stroke is not so long, but the motive-fluid can be economized, running mostly by expansion with or without the reversers. WVithout the reversers the cylinder-heads may be dropped very quickly by using springs, but the larger the wheels J 2 J 3 the more rapid the oscillation of cylinder-heads F F, especially if the pins coming in contact with cam D are very near the axles of wheels J 2 and J In Fig. 14, I have shown a means of operating the cylinder-heads, without using the systern of pulleys and belt or chain, consisting of a central oscillating pulley or disk intermittently operated by the cam D and connected with the cylinder-heads by means of rods Z Z. Buffers Z Z strike against air-cushions Z Z and bring the parts gently to rest after each oscillation.

hat I claim as my invention and desire to secure by Letters Patent, is

1. In a rotary engine, a cylinder-head operated by sprocket-chain and cam-mechanism on the revolving shaft, when running in one direction.

2. A cylinder-head, in a rotary engine, os-, cillated by sprocket-chain and cam-mechanism on the revolving shaft to run the engine in either direction.

3. Two cylinder-heads, each one near the periphery but on opposite extremities of the annular cylinder of a rotary engine, oscillated by sprocket-chain and cam-mechanism on the revolving shaft for running the engine in one direction.

4.. Two or more cylinder-heads, in a rotary engine, oscillated by sprocket-chain and cam mechanism on the revolving shaft for running the engine in either direction.

5. In a rotary engine, a revolving disk bearing adjustable valves admitting motive-fluid alternately through inlets into the annular cylinders of two or more engines.

6. In a rotary engine, a casing provided with two annular piston cylinders, a motivefluid chest intermediate said cylinders, a rotary disk supporting upon its periphery detachable valves for the respective cylinders, and inlet and exhaust ports connected with said cylinders.

7. In a rotary engine, a casing provided with two annular piston cylinders, pivoted cylinder-heads engaging at opposite points with the periphery of said cylinders, means connected with the engine shaft for intermittently oscillating said heads, a chamber intermediate said annular cylinders constituting a steam chest, motive-fluid ports connecting said chamber with said cylinder-heads, a rotary disk in said chamber provided with peripheral valves, and disks on either side of said valves provided with openings or channels cooperating with said ports, and means for determining the position of said disks to control the passage of the motive-fluid be tween said chamber and said cylinders.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
