VALVE OPERATING SYSTEM.

APPLECAUON FILED DECJI, i914.V

2 SHEETS-SHEET 2.

(18) A. bridge structune overlying the admission valves 14 and'coniprising av panof outlying brackets rising rom'tlie cylinder head and an interconnecting shaft constitut-` ing thel crown of the bridge.

(19, 20) 19, 20) Synchronously operatin/g pairs of valve rods and levers arranged to individually engage and operate exhaust valves 13. The levers 20, 20 are pivoted 0n the crown shaft of the bridge 18 which vshaft constitutes their pivotal axis. The

rods 19,19 are arranged in the sanie plane as the valve red l5.

What 'I claim is:

1. In an internal combustion engine, a. cylinder having a rnetrically arrange in its cylinder head, a single valve operating lever pivotally mounted on said head for operation in an axial plane of said cylinder and actuating one set of said valves and a pair of separate levers lalso pivotallyjmounted on said head for movement in planes parallel to but on opposite sides of the plane of the rst named lever and individually actuating another set of said valves. 4

2. In an internal combustion engine, a cylinder having a pair of exhaust valves disposed in its head and operable by separate levers, said levers being' actuated by separate valve rods and both said levers and said rods being disposed in planes-located on opposite y sides ofthe axis of the cylinder, a pair of intake valves also disposed in said cylinder head and substantially in line with said planes, a pair of inlet conduits, lsaid valves being disposed intermediate said conduits,

'and a single lever in combination `with a single valve rod mounted for movement in the axial plane disposed between the aforesaid planes to simultaneously operate said lurality of valves syni- Laeaaao sides of said single lever for operation in.

planes parallel to the plane' of actuation thereof and individually actuating said eahaust valves.

4. An internal combustion engine cornprising a cylinder, dual admission and exhaust valves associated therewith, and ar- .ranged in pairs, a bridge across the valves of one pair, operating levers for the valves of the second pairpivoted thereon and operating in synchronisrn, and a third valve lever intermediate the aforesaid pair of levers commonly operating the valves of the rst named pair of valves and engaging them below the crown of the bridge.

5. An internal lcfnnbustitm engine cornprising a cylinder, a pair of puppet valves of like character associated therewith and a common valve operatino* lever therefor having'- a T-head formed by inserting a taper pin transversely of the trunk of the lever.

6. ln an internal combustion engine a cylinder having dual admission and ehaust valves arranged in pairs according to their character and symmetrically disposed with reference to an axial plane of the cylinder, a valve operating rod and lever for one pair of said valves located in said axial plane, and individual operating valve rods and levers for the valves of the other. pair symmetrically disposed with reference to said plane.

7. ln an internal `combustion engine, a cylinder, dual admission valves therefor symmetrically located with v respect to an axial plane, a valve operating lever and rod located and operating in said plane, and a pair of admission conduits located on opposite sides thereof.

8. In an internal combustion engine, a cylinder, valves entering the cylinder, a le ver to similarly operate a pfair of said valves, an actuating rod for the lever, levers pivoted above the first said lever'to operate other of said valves and actuating rods for each of the last said levers arranged in the plane of the first said rod.

In testimony whereof l' sin my signature in presence of two witnesses.
