Be tknovvnl thatl I, yVVI'LLIAM Il, RICH MAN, acitizenof the United States7 residing in Philadelphia,:Pennsylvaniea have invent- -ed certain improvements l in.-Internal-Combustion Engines, a specification. f One ob3ect of my invention is to provide ofvvhich the` following is animprcved device for4 controlling the 'ad-V mission of exploslve chargesto the `cylinder' of an internal combustion engine which .de-
. vice shall be of such a nature and constru'cf attention even after prolonged use.
Vtion as to allow an abundance of time forv the inoW-of 'such charges Without invoiving many or complicated parts, or interference with the proper and eiiicientfoperation of the engine.' l y Another object of the invention is to prof .vide an inlet valve for internal' combustion engines which shall .not be liable to" leakage nor vbe likely toget'out of order or requireI It is further desired to provide anu-inlet valve having the above characteristics which .A
in laddition may be readily adjusted to permit the engine to be reversed..I These and other advantageous 'ends I secure as hereinafter set forth, referencebeing had to the accompanying drawings, in which: i
Figure 1,. -is a vertical section of ,an'eX-1 plosion engine constructed according to my invention; Fig. 2, is a vertical sect-ion taken on the line 2-2 Fig. l; and Figs. 3 and 4' are vertical sections, taken at right angles to each other, illustrating a modified form of my invention.
Referring to Figs. 1 and 2 of the above drawings, A is the base or crank Case of an internal combustion engine having a main shaft a and a. crank a. The engine cylinder A is mounted on the base in the customary manner and Within it is a piston B operatively attached to thecrank by a' connecting rod An inlet port 012 enters the crankcase and is connected to any suitable source of fuel for the engine. A passage b extends from tlieupper portion of the crank case toward the upper and of the engine cylinder, in the manner customary in two-cycle' encines of a Well linoivn form, and in addition there is provided inthe side of said cylinder' an'exhaust port or passage 52 for the escape of the products of combustion.
Mounted upon one side of the crank so that it may if desired, act as a counter-balrod, etc., -is a 4;subst.fitntially semi-circular nular shoe ciheld' inposition'bypins c.

One en d ofthe crankcas .cylindrical chamber for 'this 'valve structure `C and `its shoe, and. it .Willbe understood forced out bycentrifugal force', as v've'll as e forms-a flat.
'thatwvlien the. crank ist turned, saidshoe is -5 by the spring 02,-so as to closely tit the'wall'fl revoluticn ofthe shafts.

At the begin?" the fuel is compressedinftheVcrank casey and is .finally allowed 'to pass :into the?` cylinder' when the piston uncoversthe opening `into the Passage b. .1 I Justfafterthis admissionl of fuelv 'to the cylinder', theshoe. again opens the inlet-port a2 so' that theupward move- `ment of thepiston' sucks alnew charge into exploded in: any suita eration ofthe engine.
Insteadofplacing the projection or counterweightstructure C directly on the crank,- I ma in thosecasesin which it may be de# semi-annular shoe on the segmental struc` ture, though in this case I place 'springs c? to act directly onthe pins c so as to cause the shoe to make a tight jointwith the interior the crank caseandlat thesame time conipresses' that previouslyadmitted until it 1s ble manner. t'o cause op-V surface of the."chamber in Which it moves.
The operationjof. the valveformed by the part C and its shoe is the same as described in connection with the form of the invention illustrated in Figs. ll and E2, and when it is desired to reverse the direction of op- 7o chamber 'in'Which-the structure() andthe f' 'shoe .revolve',"so thatit is 'periodically'closed by said .ShoeferrsubsamnuyI 011ehanf-af noname eration of the engine,. said valve may be shifted on the shaft through an angle of 180 relatively to the crank.
'y It is obvious that the positions of the ports andthe proportions of. the various parts ofthe valve and `the chamber in which it works; may be materially changed Without departing from my invention, which provides a most simple and efficient means for controlling' the admission of fuel to an internal combustion engine.
I claim as my invention:
l. The combination in an internal combustion engine of a crank case having a cylindrical interior provided with a port openf ing into its cylindrical surface; a cylinder; a piston therein; ashat having a crank in said crank case; means for connecting the crank and the piston; a valve structure car-` ried by the shaft so as to `extend in a line substantially 180 degrees distant from the line of the crank; with a substantially semiannular shoe mounted on and 'structurally independent of said structure in position to movably coperate with the cylindrical surface ct the crank case to control the flow of iluid throughpthe port; there being a conduit for conducting luid'from the crank case to the engine cylinder; with springs between the valve structure'and vsaid shoe,v
2. The combmation 1n an internal conr' v bustion engine, of a crank case having a substantially cylindrical surface provided with a pOI't; a cylinder a piston in said cylinder;
a crank 1n the crank caso; 1
a shaft havmg a rod connecting the crank with the piston; a valve structure on the shaft; and a circularly curved strip forming a -shoe movably mounted on the valve structure in position to coperate with the port in the cylindrical surface of the crank case to controlthe low of fluid therethrough; there being means for conducting Huid from the crank case to the engine cylinder.
3. The combination in an internal combustion engine of a crank case having a cylindrical portion provided with a port; a crank shaft passing through said case; a crank on said shaft.; a semi-cylindrical structure mounted adjacent to the crank and extended from the shaft in a line substantially 180 from the line of said crank; a substantially semi-annular shoe' movably mounted on said structure in position to cooperate with the crank case Iport to control. the flow of fluid therethrough; an engine cylinder; a piston'therein; and a rod connecting the piston with the crank.
In testimony whereof, I have signed my name to this specification, in the presence ot' two subscribing Witnesses.
