Be itknown that I, ARTHUR ,B Goonsrnnn,

a citizen of the'United States, residing in Roseville, in'the State of New J ersey, have invent-m and useful Improvements in' Valve-Gear for Internal-Combustion Engines, i

ed certain new &c., of, which'the following, is a specification, reference being hadto theaccompany-v ing'drawings,iormingaparthereofi 5 This invention relates generally to I inter rial-combustion engines the typeof that shown ini ap licationfor Letters.Patent of the United construction of the valves of such engin the-engine shown- 111 said application the fuel-oil is admitted to a chamber "above the'i'nlet-valve, to which is also admitted the air under pressure, so that vide'd for the 'pur ose the oil is: carried nto the "combustionc amber by the in'rushing air. Obviously'it is im oss ible in such a con-. struction to vary the a mission of the fuel-oil v with respect to the admission bf the air.

a same time provisionis made for the-complete shutting off of both of combustion.

Another object isi t'c provide for a more thorou h atomization'of the oil as'it is admit-- directed upon the igniter, and thereted an fore for a better mirgcture of the oil and'theair, while "the oil,inevertheless, does not. lose I its physicalidentity until combustion begins. Both parts of the improved valve are hper ated together by the valve-opening means, while that part which controls the admission of oil is clapable of operationindependently of the otherlpart'to provide forthe independent regulation oftheadrnission of ,oiL. a

bu'stible mixture in the working cylinder is admitted under pressure, as from a compression-cylinder- (represented at E) .to a valvecharnber; K, which communicates, through a valve-port k; with the working cylinder, a vaporizer and igniter M being interposed between. the valve ort and theworlnn cylin 'der.

The means 'u'st described for operating the valve 712' are t e same as those'shownin said application, Serial No. 202,720 but any other suit-. able means maybe employed so far as concerns the present invention.-

Surrounding the stem of the valve kt is a sleeve 0, which carries at itsv lower end a valve of to rest upon the valve kf and to coeperate withthe valve-port is, being ressed normally to its seat upon the valve 2 and u on the the sleeve 0 and the cured on the stem ofthevalve 7c;

plication' of the inventiomto be understoo Y e oil is not admitted-to the, V as described in said former is admitted between the v described, The valve 7c",- which closes the.

guided in a suitable bracket k and ro'vided roe" Near its lower endfthef' sleeve 0.,is .chamb ered,ias at 0 about the and is provided with a 1 vided in the casting, which forms the cylinsure of the oil from its source of supply, and.

the time-oi? the lifting will in general be determined by the action of the pump or the valve which regulates the supply of oil. The exact instant of opening may, however, be regulated, as by the substitution of a different sprin 0 or by the variation of its tension, as by a justing the collar or the cap between which it is confined. In this manner the valve 0 may be arran ed to open in advance of the lifting of the va ve k. or at the same instant or later. It will be evident that when the valve is lifted from its seat the oil will be distributed radiall in a thin film upon the valve-seat and will. e instantly taken up by the inrushing air, which is also distributed in a conical sheet and also completely atomized and mixed with the air, so that immediately upon contact with the vaporizer and igniter M it will be thoroughly vaporized.-

The valveseat, as will be noted, actsas a baffle-plate against which the oil is discharged, and the relation of the oil to the aircurrent is such that the atomization of the oil is-facilitated, while at the same time the physical-condition of the oil is unchanged un' til vaporization and combustion take place. Moreover, through the regulation of the instant of discharge of the oil, as already described, the character of the mixture can be Varied as may be required under the particular conditions of operation. It willbe understood, of course, that various changes in the form and construction of' parts may be made without departing from the spirit of the invent-ion, and it is not intended to limit the invention to the precise construction and arrangement shown and described herein.
