.Livonia To all whom t may concern:

Be it known that I, RALPH T. GUYEma residing Elkhart, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Engine Valve Mechanism; and I do hereby declare the following to be a full and exact description of the invention', such as will enable others skilled in the artto which the same.4

My invention relates to internal'combustion engines and especially'to engines of the four cycle type. he objects of my invention are as follows; first, the production of an explosion engine having a novel and eflicient form of rotary valve, second, the -production of an engine having 'a rotary valve and: novel means for lubricating the same, and third, novel and efficient means for relieving the valve of the force of the explosion.

Further objects will appear /and be de-l scribed in the-specification following.

In the accompanying drawings, Figure 1 is a section inelevation through the an engine cylinder embodying the tion; Fig. 2 is a section on the line 2--2 of Fig. 1; Fig. 3 is a plan view cfg-,the valve top; Fig. fis a view in elevation of the 'preferred form of the rotary valve; and Fig. 5 isa plan-view of the valve seat on the cylinder'v head.

Similar numerals lrefer' to similar parts and members throughout the several views on the drawings.

yliumeral 1 designates' the top 'of an explosion engine cylinder bored at 2 to receive a piston 3 for reciprocation therein. The `cylinderl is provided with a water jacket 4 open at its top to communicate with the water jacket' of the cylinder head hereinafter' described.

. Numeral 5 designates a cylinder head rigidly secured to the cylinder top in any suitable manner, and closing same. The head 5 is provided,

invena `wate'r outlet opening 7. l

,he numeral designates a conical Valve seat formed Von the/surface of lthe cylinder head 5, and numerals 9 and 10 designate, exhaustand fuel intake ports, or evenings, formed inthe liead 5, in .com-

u1u-:mation with the atmosphere, and ter-4 minating at their inner ends in the exhaust atI itappertalns to make and use` top of-v with a.water jacket 6, in comvmunication with the cylinder jacket 4, and

serial No. 26,987.

and fuel inlet ports 9 and 10', respectively,

1n the-surface of the valve seat 8. The exhaust and intake ports 9 and l0 are placed, for most purposes and uses, at an interval of about ninety degrees relation .to each` other, but forspecial purposes this angle mayibe'varied and made greater or less, accordlng vto the purpose to be accomplished.

he numeral 11 designates an annular for rotation within the' bore '14 formed. in the cylinder head 5, and is also provided Patented Een. 1, 191e.

y Valve stem 12 is provided with an annular section 13 journaled' wltha squared portion 15 whichis arranged.

withinl the squared` wheel 17 with enough gitudinal movement thevalve stem' at 15. The numeral 18 desi nates a gear wheel meshing with the gear 1% and provided with one half the number of teeth carried fby the gear 17, mounted upon a shaft 19 idly secured thereto. 'The shaft-19 hole 16 of the gear play to permit of lonis driven by and at equal speed with the engine crank: drivmg means not being shown.y

the valve stem 12 by a `pin 22.` The spring 2O holds the valve 11 securely upon its seat 8 at all times, yet permitting rotation freely,

cient tension to withstand e vacuum created in the cylinder when. the piston. 3r is asprlng washer21 andv and exerts suiii descending on its suction stroke, or move` ment.

The numeral 23 designates opening formed in thel head 5 vat a point substantially opposite the port 10,.' and adapted to be closed suitable design.

` The numeral 24 by a spark plug of any i 'i .l J deslgnates a valve port,

of substantially truncated sector formation,

formed in theI valvell and extending from a point intermediate its center and periphe to the outer periphery thereof to obtain al possible port area. The port 24 is adapted to alternately-register with exhaust and intake ports 9 and lO for exhausty and l fuelintake purposes, respectivel anddur.- ing the' compression and -wor 'ng vmovements of the iston 3, is necessaril. and designed and tlme'd to be,.o ut of rem'stry or communication, With both of said ports which are closed and sealed during saidr cycles.v Y

'Ihe numeral 25 designates a squared secl tion of the valve stem 12 arranged Within i formofvalve and stem which are integral diameter.'

and made of any suitable metal, and provided with the journalv section 18. and the squared section 15 for receiving gear Wheel 17 and havingv the same functions as the correspondingly numbered parts -of the detachable valve stem l2 shown in Fig. 1.

The numeral 28 designates an oil, or lubricant, chamber formed in the cylinder head 5 and within which the lower end of valve stem section 18 rotates, and into which the conical center of the valve 11 slightly pro- 'ects. J The numeral 29 designates a lubricant supply pipe placing the oil chamber interior in communication with .the exterior of the head 5, tlirough which lubricant may be introduced to the chamber 28 by gravity or pump in any suitable manner.

Numeral 30 designates an annular oil groove formed in the upper, or seating, surface of the valve 411 adjacent its center but below the outer periphery of the oil chamber 28 and-between it and the outer periphery of the valve 11. And numerals 81 designate tangential oil grooves extend-V ing radially from the groove 80 toward the outer periphery of the valve 11 but ceasing at points betweensaid outer periphery and said groove to retain the lubricant as long as possible.

At Fig. 5 I show a plan View of the valve seat 8 and the ports 9 and 10 opening thereto. Thereon, the numerals 82 designate a plurality of radial grooves formed in' the valve seat surface and extending centrally from 'the outer periphery thereof, which is of greaterv diameter than the diameter of the valve 11, to points in a circle concentric With oil groove 80 but of greater I provide the grooves 82 not only to reduce the natural frictional resistence Kbetween the valve 11 and its seat 8,

' but also to permit the compression of the explosion to enter therein to partially relievethe valve and actuating mechanism oi' the pressure thereof, thereby obtaining pressure on both sides of the valve 11. It is understood tliat'the ignition points of the spark plug located in the opening 28 are in communication with the cylinder bore 2 when a charge is compressed therein and realy for ignition, and also that the valve 11 is rotated in the direction indicated by the arrows in Figs'. 2 and 8 to obtain the valve port registration `with the exhaust and inlet ports 9 and 10 at the proper times and for the purposesmentioned and understood.

I claim: p
