NTRNAL-COMBUSTEGN ENGINE.

Application filed September 25, 1918.

To all whom t may concern.'

Be it known that I, Ponri Us ll. lVEELER, a citizen of the United States, and a resident of Peoria, in the county ot' Peoria and State ot' Illinois7 have invented certain new and useful Improvements in lnternal-Combustion Engines, of which the following' is a full. clear, and exact description, reference beinghad to the accompanyingq drawin forming a part ot' this specification.

ly invention relates more particularly to that class ot' internal combustion engines operatinp, upon the two-stroke-cycle principle wherein a power impulse is imparted to the piston for every two strokes thereof.

One object ot' my invention is to so arrange the rvarious parts of the engine that the suctiori stroke thereof will he continuous during` substantially a halt revolution of the crank shaft.

Another object of my invention is a provision of means whereby a portion ot the charge sweeps the ignition element thus insuring' the proper ignition of the charge.

Another object ot' my invention is to arrange the Various parts of the engine so that they are easily accessible tor repair, renewal or inspection, should occasion arise.

Other objects of my invention will appear and be described in the specification.

The noveltyvoic my invention will be hereinafter more t'ully set forth and specifically pointed out in the claims.

ln the accompanyingdrawing Fig-ure l is a sectional end elevation of an engine emparts being shown in their proper relation and position at the point of ignition.

Fig. ll is a View similar to Fig: l, some ot' the parts being shown broken away, the' position and relation of the parts beiner proper foraposition about midway on the suction and compression stroke.

The saine numerals ot reference are used to indicate identical parts in both figures.

To illustrate one form ol engine in which my invention may be embodied, l represents a cylimler structure composed ot the inner cylinder wall Q, water ljacket wall- 3, valve pocket 4, and other parts to be later described. 'lhe cylindrical' piston r mounted within the cylinderfand connected by meansI ot' connecting rodttivto the (granit i cra nl; case 8. The upper portion ofthe cylindrical pis ton is provided with exhaust ports 9, suc- Specification of Letters Patent.

tion and transfer ports 10, and head 11, this head being provided with mg anda stuling box 12 and the central opening in tube 13 is passed, the tube the member 14, and carrying 15 at its lower end.

The member 1112 is secured to the upper portion of the cylinder structure `as by means of cap screws 16. The valve pocket 4 is provided with the valve 17 which may be the usual form ot' puppet valve, or any other suitable form of valve and is provided w1th a downwardly extendingn stem 18 and spring` 19 which serves to normally hold the valve 17 against its seat. The valve actuating mechanism comprises a link 2O which is connected to the connecting' rod 6 at one end and to the bell crank 2l at the other end, the bell crank 21 beingmounted upon the valve lifterr guide 22 as clearly shown, the guide carrying the valve lifter 23 which is adjustable as by means of the cap nut 24 and lock nut 25 so that the parte may be set to insure the proper operation of the valve 17.

At the head end of its travel one of the exhaust ports 9 of the cylindrical piston 5 registers with the ignition port 26 as shown the head 11, a being held in a piston head vin Fig. l and any suitable form of ignition device such as the spark plug 27 may be provided for the ignition of the char e, while at the lower end of the travel of t e cylindrical piston 5 one of the exhaust ports S) registers with the exhaust port 28 through which the spent gases pass to the exhaust manifold 29. v

An annular inlet port 30 is formed in the cylinder structure and communicates with the valve pocket 4 and with the inlet and transfer ton 5.

lt is to he noted that the inlet and transfer ports 10 are ot such length and location thaft immediately after the beginningf of the registration of the exhaust portl with the exhaustpassage 28, the lower edge ot thc inlet wand 'transfer ports 1() pass below thelower edge oi the pistonA head 15 to permit the charge to transfer as will be later described. v lt is also to he noted that the piston head 'l5' is a-t all'tiines stationary with relation to the cylinder structure andto facilitate the control ot' its temperature during lthe operation oi the engine it may be provided a central open-j through which,

ports l() ot the cylindrical pis-,

n ileeeee ing cylinder and a combustion space, a snp port for said stationary piston head seid support passing` through the charging portion of said cylinder piston7 e removable head sun' rounding said support and carried'by said cylindrical piston, cooling medium inleiJ and outletpassages in said support and communioating with a cooling medium space in said stationary piston head, a valve in the inlet passage of seid cylinder structure, and oonnections between a moving part of the engine and a valve lifter whereby said valve may be raised from its seat during the suction stroke of the engine.

In an internal combustion engine the combination of a cylinder structure, e eyl lindrical piston therein and connected edja- 'cent one end to operate a crank shaft, a removable head in the drical piston-'and arranged stuing box, a support carried by other end ofV the eylm` lie cylinder srnoeurej e 'nbe depending from the support and passing through the stuiiingbofi of the head of the eyliiiidrieal piston, a piston bead carried by alle lower end of Jche tube and provided with ii eenling medium chamber the piston liead dividing the cylindrical piston into charging and combustion Cylinders, ineens for cirenlating2 2L cooling medium through die piston head and its tubular support, in admission and transfer port in tbe cylindrical piston, an ignition device carried by the Cylinder strueture and registering with the transfer port during the transfer of :i charge whereby the charge will sweep the ignition device, and an ignition and exhaust; port registering with the ignition device for the "l the charge and with an exhaust port in the cylinder structure for the exhaust of the eo charge.
