/ To all- 2121mm it nay concern: it known that, IgJrrirEs Knis'rnn, a citi- .:zen or the imtedyStates, and 21V resident of .Steubenville, intnecounty of Jefferson and State of Ohio, have invented a new and Improved Internal Combustion Engine, of which the following is a tull clear, and
exact description.
I T his invention relates to internal combus i .UOILQIlgiDGS of the four-cycle type, and par-o tic-ularly to engine'sot that character wherein theadnnssion of tl'lE QXPlOSIYG fluid and theexhaust of the spent gases are controlled bya single tubular valve which surrounds the piston of the engine. xMore specifically, the invent-lon'relatesto an eng ne of that type dlsclosed in my pending= application forLetters Patent Serial. Number 770.3%7, file-d. May 28,1913, wherein the tubular va-lve is provided with separate [inlet and exhaust ports and has two-step stroke in one dire n for opening the exto. improve and simplify the construction of haust port during one step and closing the exhaust port and opening the admission port during the next step said steps being synchronous respectively with the exhaust and suction strokes of the piston, and in the return movement thepist-on moves in one step .to jclose the ,portsduring' the compression and firing strokes.
The general objects of the lnvention are the valve-operating mechanism so as to he ,signed as to be readily assembled or disasreliahle and etiicient in use, comparatively niexpensive to manufacture, and so de- ;.senibled.
-- More specifically the object of the invention isto provide an mproved cam mechanism for operating the sliding tubular valve.
such mechanism including a spring which is located at the side of' the cam shaft zoppositetrom thecam-actuated operating lever for the tubular valve, there being link 1.connectionsbetweenthe leveran'd the spring ."for uniting said parts.
With these objects in, view and others which willappear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts such as will be set forth with particularity in the following description and claims appended hereto.
In the accompanying drawing. which illustrates one embodiment ot' the nvention. and wherein similar characters of reference "valve 5'. underthe cam shait '17, andhas its lower "end detachabl'y engaged with an anchor 23 e I Specification of 'LetteirsIf ateiit.

Figure l, is. a longitudinal section taken cylindertFig. is adiagrammatic view of on a plane coincident with the axis of the.
the cam for operating. the valve; and Fig. 3
is providedwith a fixed tubular bore element 4 which is of uniform diameter and in which reciprocates the tubular valve 5,
which is somewhat longer than the bore element 4. Mounted for reciprocation in the valve 5 is the piston 6, which has a wrist pin 7 connected by a rod ,8 with the crank 9 arranged within the crank casing or base 10 to which the cylinder A is secured. The head 11 of the cylinder has a rc'e'ntrant portion 12 which enters the tubular valve 5 and bore element 4cwhichcooperateswith the piston 6 to form an explosion chamber 13. The inlet and exhaustpassages 2 and 3 are adapted to communicate respectively through the ports 14, 14 and 15, 15 in the bore element st and valve-5 respectively. The inlet port 143 oi the valve is so arranged that it will be out of alinernent with the inlet port'14 while the exhaust port 15 is ;in registry with. the port 15, so that at no ime will the explosion chamber 13 commuspeed shaft 17 suitably driven from the v crank shaft 9, and riding on the periphery of this cam 16-is a roller 18 carried on the outer end of 'a'lever 19 that is disposed in the base 10 and iulcrumed-atQO, there being aspriiigfll to hold'the-roller ls against the cam 16. The leverlS) is connected by-a link or rod 22 with the lower or outer end of the The spring 21 is'located directly fastened in the bottom "21 of the base section of the crank case. The upper end of the spring terminates at the plane 0; division l ctween the lower section ".7 and upper. section 26 of the crank case and has a hook 27
