To all whom 'it may concern.'
Be it known that. I, WILLIAM OTTAWAY, a citizen of the United States, and a resident of Aurora, 'in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Explosive- Engines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forma part of this specifica-tion.
This invention relates to an improvement in explosive engines and consists in the matters hereinafter described andmore particularly pointed out in the appended claims.
In the drawingsz-Figure l is a longitudinal section through the cylinder of an explosive engine provided with my improvement, the section being in a 'plane passing through the central axes of the exhaust and intake valves, and the central axis ofthe cylinder. Fig. 2 is a cross-section through Fig. l on the line 2 2 thereof. Fig. 3 is a partial section through Fig. l on the line 3-3 thereof. Fig. 4 is a perspective view of the adjusting sleeve secured to the end of the inlet valve stem. Fig. 5 is a perspective view of the collar for the inlet valve stem. Fig. 6 is a perspective view of the sleeve secured to the end of the exhaust valve stem. Fig. 7 is a perspective view of the collar for the exhaust valve stem.
In the drawings A represents `the cylinder; B, the piston:l B1the connecting rod pivotally connected to the piston by means of a-pin 6,' C, the explosion chamber; I), the inlet valve dome; E, the inlet valve, and F, the exhaust valve.
F1 represents the exhaust valve stem and- 5F the exhaust valve seat.
J is the reciprocating lifting rod which actuates the exhaust valve.
rIhe lower end of the valve stem is threaded, as indicated at F2.
G indicates a sleeve provided with a head g at one end and at its opposite end *with a. threaded recess g1 to receive the threaded end F2 of the valve stem. Said sleeve is split longitudinally, as indicated at g2, from its upper end to points near the head. They outer surface of the sleeve body is tapered, as shown at ga.
H indicates a collar provided with a tapered recess 11.1 to tit the tapered body of the sleeve. This collar has an annular flange ragainst which bears Aa coil spring I -which normally holds the exhaust valve in' Iengagement with the lseat. The other end of said spring engages an annular flanged lring h2 which is rigidly mountedy on the valve stem guide-ring F3. The collar H clamps the longitudinally split sections of the sleeve upon the threads of the valve `stem and thereby holds the sleeve from turning on said stem. The valve-actuating spring I exerts constant pressure on the collar, tending to force itl toward the lower or larger end of the tapered split sleeve,
and thereby maintains the sleeve in clamping engagement .with the screw-threaded end of the valve stem. This construction provides, in the case of the exhaust valve, a simple and reliable device for adjusting the position relatively to the valve disk, of the part which is acted on by the lifting rod J, as required for regulating the lift of the ,valve from its seat. `Such adjustment is effected by lifting the collar I-I a sutlicient distance to release the split parts of the tapered sleeve Gr from their clamping engagement -with the valve stem and then turning the said sleeve to move it up or down on the 'screw-threaded end of the valve stem, until the lower end of the sleeve is brought into the desired vertical lposition with relation tothe lifting rod J. i When the collar I-I is again allowed to seat itself on the tapered outer surface of the split sleeve, it ac ts to clamp and hold the split parts of the same immovably upon the stem. The constant pressure of the spring on the collar alwaystends to tighten the parts, or' to hold them firmly in contact with each other, so that there will be no liability of the same becoming loose, or the adjustment of the valve stem being changed, by the jarring of the parts occurring 1n the operation of the engine. A sim1lar construction is used for adjusting the opening of the inlet valve.
El is the inlet valve stem and e a guide ringin which said valve stem slides.
K is a tapered, internally threaded sleeve split longitudinally at K2 and K1 is a collar provided with a tapered recess K3 within which the tapered sleeve its. Said collar is provided with an annular shoulder 7c in which is formed an annular recess 701 to receive the upper end of a coiled spring L which normally holds the intake valve in closed position against its seat. The lower end of said spring bears against a shoulder Z formed in the guide ring e.
When the inlet valve is opened it moves away from its seat until the lower end of the collar K1 strikes the upper end of the guide ring e. It is thus apparent, that the position of the collarl1 on the valve vstein and of the sleeve K on the stem, which determines that position, limits the opening of the valve. By withdrawing the collar and adjusting the sleeve K up or down on the valve stem, the amount of the opening of the valve maybe adjusted. The -sleeve K is preferably provided with diametrically opposed flat parts k2 near its upper end for turning it by means of a wrench. The head of the sleeve G is made hexagonal, as shown at gt, for.
the same purpose.
The construction described is quite simple and at the same time provides for the ready adjustment of the valve opening, both intake and exhaust. In addition the parts are locked in their adjusted positions without the use of pins and holes in the collar or valve stem which tend to weaken them.
It will be noted that in case of the exhaust valve, the split sleeve constitutes an adjustable partv which is acted on by the valve actuating means and controls the extent of lift of the valve while in the case of the intake-valve the collar constitutes an' adjust-y able part which by its contact with a fixed stop likewise limits the lift of the valve. It is to be understood, however, that the novel construction .described mightl be applied in a construction wherein neither said sleeve or collar comes in Contact with any other Lumens rod which is subject to the pressure of a V spring exerted endwise thereon.
l claim as my invention :-4
l. The combination with a valve-stem, of a' sleeve surrounding and having screwthreaded connection with the stem, said sleeve having a smooth, tapered external surface and being split longitudinally in its tapered part,a collar fitting upon the tapered exterior ot the sleeve, and a spring acting on said collar in adirect-ion to force the same upon the tapered sleeve and to thereby hold the .said sleeve in clamping enga-gement with the stem.
2. The combination vwith a valve-stem or like part, and a coiled actuating spring which surrounds the same, of a sleeve which surrounds and has screw-threaded engagement with the stem, said sleeve having a partwhich is longitudinally split, and a smooth, tapered external surface on its split portion, a collar provided with a tapered bore adapt ed to lit upon the tapered surface of said sleeve, said spring acting on the said collar to torce the same upon the tapered sleeve and to thereby clamp the sleeve upon the stem.
