,Toaawllomitmoycmmi Be it known that 1, DAVID Room, a aubect of theKing of Great Britain, reai at to "Iron Worka, mm, Linco d, have invented new and neoful Impwementa in Internal-Combuation I which the following in a apeciflca on.
I My invention relatea 'to internal combuation ace in which hydrocarbon fuel il ueed an to that type. of auch engine wherein the vaporiaer or combustion chamber ia formed an anextenaion of the cylinder and connected to it by. a more or leaa contracted 18 neck or paaaage. The vaperiaer or co bultionchamberofauchanenginehal, aome caaea, been divided into twaportiona, a hot and a cell! or wabr-jaoke art, and in othereaaea, ha been whe'llyj we. In :0 their inlet and enhauat outlet valvea have i uently .been arrangedin one valve-box m a pa-e common to the valvea opening direetin thecylmder ropar, and new timea 2e tglbagvea havzh'hn-gn in :8 v xea opemng '.d1rec" t into iii? p wa - with air inlet-v ve o direct into the vapon'ler or comb on c amber'and the exhauat.outlet-valve a aepa rate'valve-box with a,paaaage direct intoJhe cylinderaprofer. 1th the ehove arrengemente e ope-of com reeaionthatoanbeuaedialinntedbythe arge 8i clearance apa'cee niceaeitate'd by each arrangem'ant and alao the power and etiiciency obtainpdjroni a cylinder otgiven nae have been hnuted owing to the amount of inert air contained in the above named clearance apacea and varioua paaaagea and valve boxea outeide the vaporizer or cornbuation chamber, and the large euriace m the port and expoeod to the hot gain during the combustion stroke.
My inmntion ban for its object tobenable enginea' vaporizere or 'com uatien chambera above-named type to develop ore power tvith a cylinder of Elfin aize d give gnileater efliciency than hitherto, 3y obtaining 'gher compreaaion and introuem va or combuetiop ehakmberaluring the en teeom reeeionatreean e ite own cylinder caeea alao the have beenaralninimum of aurface to contact with during the comhu'etion atmlte, by do- -ing away with the uaual porta and paaaagea a greater proportion of air into,the-
between the va riaer or combuetion chamher and the c'y der and air inlet and exhauet outlet valvee.
In carry out my invention I a an 0 hi erabl onthe oftheco or wa ter a nx'eted pazt of the i a pioriner or combuation chamber, which opemn acta alteror the ma of the iaton t and'in either use are pref rably one a flecting valve and the ower the exhaust deflectingvalve. Theae valvce'may also be of the mushroom tygn arranged side by side or the accompanying drawings, in which:-

e ll the contracted passage by which the water-jacketed part c of the vaporizer is connected to the cylinder a and f is the oil-inlet.
g is the opening in the art e of the vaporiser which opening acts a ternately as the air inlet and the exhaust outlet h is the sealing valve opening inwardly and controlling the opening g.
its t iechamber in whichare arranged the air inlets k and theexhaustoutlets j. r
l is the air deflecting-valve, and m is the exhaust deflecting valve, the said valves-being of any of the types andarranged as illustrated in the accompanyin drawings.
In engines working on tlo ()tto or fourstroke cycle the valves perform the following functions. The main sealing valve it closes the opening 9 in the side of the wateriacketed part c of the vaporizer thereby o a seal during the combustion stroke; this v ve also controls the time of comple-' tion of the air inlet or induction stroke and the time of commencement of the exhaust or outlet stroke. The air deflecting valve 1 controls the time of commencement of the air inlet or induction stroke and the exhaust deflec valve-m controls the time of completion the exhaust or outlet stroke. With t ment of valves the air and exhaust deflecting valves have practically no pressure to resist, and the exhaust valve, if of the double-beat drop-type or piston type, is so arranged that as it, opens it enters into a chamber above it and immediatel beneath theair valve, and ,thugis practical y shielded from aetionsn the issuing ahaust sees; the maximum pressure due to the exp osion or combustion stroke is resisted by the main sealing1 vslve, am to 1111!! main sealing v intoteva rizeror eombrf the clesran spaces are reduced to a minimum, thereby minimizing the amount of heat lost b conduction to the water acket and by rs 'ation with the increased power and efficiency are obtained.
The main valve hand the air and $0 exhaust deflecting valves 1 and m may be operated may of the well-known means so as to isle proper sequence of operations and al nghs'uy invention isahown a plied to a horizontal type of engin it will obvious 88 that it may equally well I 'applied to other,
