My invention relates to internal combustion engines, and consists in the improvements hereinafter described and shown in Figure 1, is an elevation, looking at the one "end of the main shaft, the supporting standard which is toward the observer being removed. Fig. 2, is a vertical central section in a plane at right angles to the plane of the picture of Fig. 1. Fig. 3, is a detail view, showing the train of gearing connecting the shaft and rotary casing. Fig. 4, is a detail elevation, showing the valve operating mechanism. Fi 5, is a detail, showing one end of a cylinder and illustrating the valve operating mechanism and its relation to the valve. Fig. 6, is a perspective View of the valve operating mechanism. Fig. 7, is an enlarged detail of one end of one of the cylinders, showing a method of making electrical contact. Fig. 8, is a detail view in section, illustrating the mechanism for holding the valve operating mechanism in an adjusted position. Fig. 9, is a detail sectional view, illustrating the mechanism for "operationis shown.

altering the angular position at which elec trical contact is made. Fig. 10, isa detail view, illustrating a portion of the: exhaust ap aratus. 1

n the drawings an internal combustion engine employing the four cycle method of 'A, A, are standards upon which the engine is sugported.

B; B B are four radially disposed cylinders secured to a casing C. The casing C is provided with trunnions G which rest, f in bearings G on the standardsA, D is the main shaft resting in bearings D D in the trunnion C of the casing G.

D and D are two adjacent cranks forming part of the shaft D. Apair r pistons.

b, 6 are connected by connecting rods 6 b to. a crank D The connections to the crank D are entirely similar to that of those to D, so that they need not be specifically described.

E is a gear wheel upon the shaft D.

H is a gear wheel upon the trunnion. C of the casing C.

F and G are intermediate gear wheels joining the gear wheels E and H, so that the casing C. shall turn in the same direction as the shaft D, and have halfthe angular velocity ofsaid shaft.

I, I are intake valves. The charge is sup plied to said valves'and'to the correspondin valves of the cylinders 13 and B through the pipe J, and the radially extending pipes I 1, I", and I. The pipe J is stationary, and opens into a chamber in a trunnion-C of the casing C, with which chamber the radial pipes just referred to connect. The end of ltJhe pipe J may be surrounded by a stuifing K, K are exhaust valves; the cylinders B and B are provided with similar exhaust valves. The exhaust from the'four cylinders is conveyed 'igrough radial pipes, two" of which, K, and d are shotvn in Fig. 2, similar to the induction pipes above described. The exhaust pipes open into a chamber surrounding a trunnion C? at the opposite side of the engine to that at which the pipe J is located. The chamber into which the exhaust is discharged, is made up of a plate Ifi connect'ed with the casing C of the engine, a 7 tionary plate L and a baflle ring L, acts'as a shield to protectthe bearing.

Lisa pipe conveying the exhaust from the chamber to which it has been delivered by the radial exhaust pipes.

M, M M M", are con-tact pieces shown ;as extending from the sparking plugs in the,cylinder;

M, M, are-radius rods between the outer ends of which passes a horizontal rod M carefully insulated from said radial rods. The contact pieces M, M 1W, 1V are lo-' cated in difierentplanes, and therefore-each will require a special corresponding contact iece m. The radius rods M may be adusted to different radial positions.

A A are rodsextending upward from the standards A, A.

9 evaso'e N is a rod extending horizontally between the standards A, A, near the lower ends of' said standards. 1

N is a rod extending horizontally between the upper ends, of the standards A, A There is a shaft P resting in bearings adjacent to each pair of valves 1, K, on each ,cylinderflFrom' each shaft I extend arms P P 1 ,1 and toward the ends of each of said-shafts is a cam P and a cam P, the former of said cams adapted to operate the inlet valve,.-and the latter the exhaust valve. 1 The arms P ,P Pfland'l form lugs which strike against a rod N or Nfithus turning ashaftP through one quadrantat each con- -tact. i

I. (Figs. 6 and 8) are notcheslocated 1 one quadrant apart at one end of each of the shafts'P, and in the periphery thereof.

. P is a latch adapted to engage in a notch Pito hold the shaft P at adefinite angular position. Each time that one of. the radial rods from a shaft P strikes againsta rod N or]. N the shaft is moved through one quadrant. When a cam P. or 1? is turned to the nroperposition, it rai'sesthe inlet or spring. connections extendin exhaustfvalve from its seat, and when it passes said position, said valve is returned again to its seat by its proper spring in the usuallway. While I have shown the radius rod; and theconnectionsm, M and the from the sparking plugs, as one way 0 making the electrical connections of the secondary. atj

different points, still other ways may be de- ,and-the ,method of making this connection 4-0..'Will be well-understoodby those cognizant vised, and in any case, the time of sparking will probably be adjustedby the primary connection if the jump spark systemis used,

Withthe art, and will need'no explanation. ,Ijtwill" be observed that there is but one deadpoint to each pair of c linders for'each i in a bearing, a main shaft resting in a bear- I ing in said trunnlon, one or more cylinders revolution of the main sha D.

@WhatIclaim is: t V 1. In an engine, the combination of a crank case provided with a trunnion resting upon-said crank case, a stationary and a .movablewall' surrounding said trunnion and inclosing a chamber, a pipe extending from the port or ports of said cylinder or cylinders to said chamber, and an outlet passa e in the stationary part of the walls surroun 'in'the stationary part of the wallssurroun ing said chamber, and a. shield L for keeping the exhaust gases from the bearing.

3. In an engine, the combination of a revoluble cylinder,a valve in said cylinder, a rotarypart pivoted on said cylinder adapted to actuate said valve, a lug connected with said rotary part adapted to contact a stationarypart to turn said rotary part, and a stationary part adapted to be contacted by said lu'g.

4. In an engine, the combination of a revoluble cylinder, a valve in said cylinder, a rotary part pivotedonsaid'cylinder adapted to actuate said valve,,a lug'connected with saidrotary part adapted to contact a stationary part to turn said rotary part, a stationary part adapted to'be contacted by Said lug, a cam on said rotary part and means for holding said" cam at its various adjusted positions.

5. In an engine, thecombination of a revoluble cylinder, a valve in said cylinder, a rotary part pivoted on said cylinder, adapted to actuate said valve, 'a lug connected with said rotary part adapted to contact a stationary part to turn said rotary part, a stationary part adapted to be contacted by said lug, notches on said rotary part, and a stationary pawl adapted to engage said .notches, for the purpose described.

In testimony whereof, I sign this specification in the presence of two witnesses.
