gg? M te. ily known that l, llouiziir A. lli-'.vxonos, 1 a citizen of the United States, residine at. lietroit, county of \Viiyne, tritate of A\liehi gan, have invented a certain new and useful lni|uovi \.mcnt in lnternal-Coinlnistion lneines. and declare the following to he a full, clear, and exact. description of the same, such as'will ciiahle others skilled in the art to which it pertiiiiis to make aiul use the saine. reference heine; had to the accompanying.,r drawings, which form a part. o this vspeciliration.

'lhis invention relates te internal combus- Itien engines.

i 'l'hc particular obl'ect of the inveiitiou is to provide an oscillating: valve, which alleruately covers the induction and ediictioii ports, and is actuated to control the, intro- -diietiou ol' fuel and the expulsion of the products of conihustion produced in the en' igiue. t ln the drawingsi-Figarc 1, is a plan iview of two cylinders, provided with oscillating.: valves. Fig. 2, is a sectional clevation at the line a-a of liig. l. Fig. Il, is-a zsidetelevation. Fig. 4, is'a perspective of4 `a single valve.

'lhe invention is shown as applied te a ,pair of cylinders, hut it is equally ap ilicahle 'to single. cylinders, or to any iiiiiltip e num- ;her ol cylinders.

' Across the. top of the cylinder 1 is a diafiu'iisie-. 2i tei'iiaatiiisthe Qeiiiliiisten chamber of the cylinder, and perforatedl with passages 3 and 't which are, respec-- tively, the intake and exhaust passages oft the cylinder. Beyond the diaphragm 2 they perforation is continued as n passage into the exterior water jacket. li, and communicating through side passage tt, ou tha oiui side, with tha feed supply, nud through pasis inserted a valve stein S, which, on the interior end, luis secured lo it a segment' shaped valve 0. (hi its outer side it'. hasI secured to it a crank arm l0, which crank arm is provided at its extremity with a wrist pin 1l. that. engages in the race l2 of a eam t3. 'lhe cani is driven in rotation hy a shaft ll, mounted iu hearings across tlm axis ol` theengiue, and carrying: at its cnil if, which projects heyond th. cylinder hody. a spiral gear itl, which meshes with a spiral gear t7 on vertical shaftl. 'lhe vertical shaft. has its axis parallel with the axis of hearings 10 and 20 on the engine ciising, an'd at its lower end is provided with al spiral gear 2,1 that meshes with the spiral. gear 22 on the engine shaft. l'The several sage 7.on the opposite side with the. exhaust, conduit. Through the head of the cylinder desired timingI of oscillation of the valve Si,v

' oscillation for cach revolution of the crank.

If the engine is of the four c vele variety, there should he one oscillation of the valve for two revolutions of the crank.

lt is desirahle that in addition to timing the valve to oscillate as ahove described. it should also he arranged to produce :i dit'- ferential movement. iu its oscillation. so that. there may he quick opening'. a long durat ion of opening, and quick shutting ot hoth the intake and the exhaust. ports, and this is provided for hy living to the valve an irreg uhir movement of oscillation hv the cani coniiection of the arm l0, and the. cam lf.. l prefer to extend the valve nearly across the entire upper face of the cvliuder, and in order that the valve. may lieso extended, provision is ninde at the side of the cylinder for the full oscillation of the valve. which swings into the pockets Q3 and .'.t. yThe upper face of the valve is lubricated h v oil that passes in through the oil conduits Q5, and reaches the iipper face of the valve near its connection with the stein S. 'l`he oscillation of the valve forces the oil on the surface of it h v centrifugal action over the entiic face. Where more than a single cylinder is used, the shaft 14 is provided with a driving cam for each cylinder. 'A second driv- .-.iic am is illiisti'atcsletin. Fim 1. Pref.;

which is determined by the character of the'` engine with which the'v-alvc is used. `lf the "er:ilil the. vulve stein has n slight. freedom .;.fitiiilinal movement of the vali'e stem he` lauch that the. valve can move more than u l, i very lniuied dist ance, simply enough to peri -,nuty a free clearance of the valve from its i fseat. at all times in operation, a cleiiraiice that: generally completely closed by the oil -paekiug that oeeuis ietween the valve and its seat, hut which is measured in very smell iuuits of measurement.

What'I l claim is ivalvo pivoted eccentric to the axis of the cyli ing oscillation of said valve, substantially as 1 described.
