mnosrvn-nuemn.

Be it known that we, LEE A. Fauna, a

' citizen of the United States, residin at C0- lumbus, in the county of Franklin, tate of Ohio, and WILLIAM J. Mum, a citizen of the United States, residin at Springfield, in the county of Clark an State of Ohio, have invented certain new and useful Improvements in Explosive-Engines, of which the following is a specification.

This invention relates to improvements in explosive engines.

The objects of the-invention are to rovide improved means for cooling the va ves and cylinders.

The invention consists in the constructions' and combination of parts hereinafter described and set forth in the claims.

In the accompanyin drawings, Fi ure 1 is a side elevation part y in section 0 a device embodying this invention. Fig. 2 is a vertical sectional view through one of the c linders, its air jacket, supply and exhaust c ambers and connected parts. Fi 3 is a side elevation of a ortion of the air jacketof one of the cylin ers. Fig. 4 is a bottom' plan view of the air. jacket. Fig. 5 is a detail view of the fan showing t hub and 1 projections.

Like parts are represented by similar spective cylinders o characters of reference in the several views.

In the said drawin a a represent the rethe engine, four of which are shown in the present instance.

a is the piston connected in the usual way with the crank-shaft. Connected integrally with the upper end of the c linder and opening 'theremto is the com nstion chamber, (1?, in the walls of which are the outlet and inlet openings communicating, respectively, with the supply and exhaust chambers, a a, arranged o posite each other in the resent instance. T eseo enings are closed by the spring-pressed va ves, a. a, o erated in the usual way. Bolts, a secure 8 e valve chambers to the combustion chamr. Surrounding the cylinder and combustion chamber is an air jacket or casing, I), having olpenings b and b o posite the openings in t e combustion cham er to permit the insertion of the exhaust and supply chambers.

This airsjacket fits snugly about the exhaust and supply chambers, which chambers are Specification of Letters l'atent. Application filed au ust 3, 1908. Serial No. 446,550.

7 provided, res ectivel y, with shoulders 'or anges, a. an a fitting closely against the outside of the said air-jacket; the bolts, 0, which secure the parts together passing through these flanges and the air-jacket and bein secured in the walls of the com- .bustion c amber. The air-jacket is further and communicating therewith is an air-conduit, b, adapted to receive a supply of air from a fan, c, of any suitable construction,

secured to the starting shaft, d, which starting shaft is cared to the crank shaft f of the angle. 0 air jacket is sufiicient-ly removed from the cy inder and combustion. chamber to permit the free passage .of the air about these parts, but the lower part of the air-jacket is part1 closed by the lower series of spines or spi es, b, so as to form in effect a series of openings, b, at the lower end of the air-jacket to retard the passage of the air, so as to cause aeo iderable portion of it to pass out aroun d the exhaust valve chamber, which is one of the most highly heated portions of an en 'ne of this character. The flange, a, of t e exhaust ber, and formed inthe air jacket and adapted toregisterwith these openmgs, a. ,is-a series of openings, 6. Also located in the air jgcket directly beneath the exhaust chamr is a second series of openings, b. By

this construction it will be seen that a con? siderable portion of the air is dischar e completely about the exhaust valve chamie'r through the series of openings before the air has become heated to a extentffrom the other parts, the remain er of the air passing down about the cylinder and through the openings, 1).

Having thus described the invention, we claim:' r

1. In a hydrocarbon engine, the combination with a cylinder, of a jacket which parmngs, a", ar-

tially incloses said cylinder, an air conduit which communicates With said jacket at the top of the cylinder, said air jacket being closed with the exception of a few small openings at the bottom thereof, and a valve casing also surrounded by said air jacket, said air jacket having a number of openings formed in the wall thereof adjacent said valve casing.

2. In a gas engine, the combination with a plurality of cylinders, and air jackets partially inclosing each of said cylinders, a fan, a conduit leading from said fan and extending along the tops of all of said cylinders, said conduits being in communication with each of the air ackets at the top thereof, valve casings also inclosed by said air jackets, said air jackets having a number of openings formed in the walls thereof adjacent said valve casings, and said air jackets being closed at their bottoms with the except-ion of a few small openings to thereby cause the major portion of the air from the conduit to pass out around the valve casings.

3. In a gas engine, the combination with a plurality of cylinders, of air jackets par- Win34 tially inclosing each of said cylinders, a fan, a conduit leading from said fan and extending along the tops of all of said cylinders, said conduits being in communication with each of the air jackets at the top thereof, valve'casings also inclosed by said air jackets, said air jackets having a num'- LEE A.
