tion engines, and has for its ,object to provid'e an improved engine of a type employing a plurality of cylinders, the cylinders being arranged in parallel relation around a common center at which the driven shaft is located, the axis of the shaft being paral- The power is transmitted to the'main shaft by means of radial crank shafts to which the pistons are connected, and each crank shaft has a pinion fective arrangement for a multicylinder engine.

The cylinders are all mounted in position on the crank case, atone end thereof, so

that they are conveniently accessible, and the inlet and exhaust connections, aswell as the connections for the cooling system, are easily made. Each cylinder is provided withsuitablc valves which are operated by'.

of the crank case, the symmetrical arrange- 1n parallelism around a common center at which is, located themain shaft 19 which extends through the opposite end of the crank case, having a bearing. at 20 in theend 8 and another bearing at 21, in the opposite end. Each cylinder has awater jacket 10, and aguide 9 for thevalve rod 16. These rods are preferably-located on the inner side of each cylinder and each rod is connected 'at its outer end, at 14, to arocker 14 which turns on apivot 15 on apost 15 at the top of the cylinder. Theinlet valve 12 and the exhaust valve 13 are lo-- cated in the cylinder head, and thestems 12 and 13 thereof extend through the head to contact with the opposite ends of the rockerlit, atsurfaces 14 and l4",respecvtively,springs 12 and 13 tending to .close'the valves. The inlet connections are indicated at 30 and the exhaust connections at 31, the latter extending to anexhaust manifold 32 communicating with anoutlet pipe 33, the' manifold being in the form of a ring. The inlet manifold, not shown, may have a simi lar form.

The cylinders are located over' corresponding openings in the crank case end, and each cylinder has apiston 22 connected by arod 23 to a crank 24: which is mounted inhangers 25 and 26 on the inside of the crank case, and the outer end of each crank has astub shaft 24 carrying apinion 27 which meshes with alarge ring gear 28 mounted at 19 onarms 19* projecting from themain shaft 19. Said shaft-also carries acam plate 18 which hasneutral surfaces 18 permitting both valves to be closed,raisers 18 to open the exhaust valves, and drops 18 to permit the Patented July 20, 1915. I

the stems being "provided .with.

inlet valves to open. In the arrangement shown, having seven cylinders, there will be four rises and drops arranged symmetrically around the'cam. Each valve rod has aspring 17 which holds'the roller'17 ,at the inner end of the rod, against the cam plate and which operates the rod to open the inlet valve; The rod is squared as at 16 Where is passes through the opening 8 in theend plate 8 of the crank case. 4

In operation, the explosion of the motive fluid in the cylinders turns the crank shafts which through the several pinions and the.

main gear drives the main shaft, and thecam plate 18 carried thereby operates the valves in proper succession to control the inlet to and exhaust from the several cylinders.

The invention is not limited to the particular number of cylinders, nor to the other features shown and described, except as in dicated in the following claims; therefore changes may be made Within the scope of the invention.

What I claim as new is 1. The combination of a crank case, a

- main shaft extending therein, a plurality of cylinders mounted in parallelism on one end of the crank case and around a common center at the axis of the shaft, inlet and ex haust valves on each cylinder, operating devices for the valves of each cylinder including a rod extending through the end of the crank case, and means Within the crank case, actuated by the main shaft, for operating said rods. r

' 2. The combination of a crank case, a main'shaft therein, a cylinder on the end of the crank case, parallel to the axis of the main shaft, a rocker on the outer end of the cylinder, inlet. and exhaust valves on the cylinder, operatively connected to said rocker, a reciprocating. rod Working through the end of the. crank case, parallel to said cylinder and connectedat its outer end to said rocker, and. a cam plate on the main shaft,bearing against the inner end of said rod.

3. The combination of a crank case, a main shaft extending thereln, a plurality of parallel cylinders arranged in a ring on one end of the case, around the axis of the main shaft to operate said-rods.

In testimony whereof, I afiix my signature 7,

in presence of two Witnesses.
