Claims. (Cl. 123 188) Our invention relates to valve mechanisms for gas engines, and the objects of our invention are: a First, to provide forv preventing the collection of carbon or other deleteriou s'r'natter around the ;valve stem, particularly the' exhaust valve stem of an internal combustion engine, thereby preventing sticking of the valve due to the accumulated carbon binding in the valve stem guide;
Second, to provide a mechanism of this class which may be readily and quickly installed in a conventional internal combustion engine;
Third, to provide a mechanism of this class which in no wise interferes with the normal operation of the valves; a
Fourth, to provide a mechanism of this class which is particularly simple and economical of manufacture;
Fifth, to provide-a mechanism of this class which not only prevents the accumulation of zq; carbon on the valve stem but also tends to main tain the stem ina lubricated condition particularly at its juncture-with the guide;
Sixth, to provide a mechanism of this class which prevents undue heating of the valve stem particularly at the juncture with its guide; and
Seventh, to provide on the whole a novelly constructed valve stem cleaner for'internal combustion engines which is simple and economical of manufacture, durablefeflicient in its action and which will not readily deteriorate or get out of order. f
With these and other objects in view as will appear hereinaftenour invention consists'of certain novel features of constructiomcombination vand arrangement of parts and portions as will be] hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form. a. '40 part of this application, infwhichi Figure l is an outline view of a conventional exhaust valve and its stem with adjacent ,portions of a cylinder block shown fragmentarily and in section, and illustrating our mechanism in position by means of a longitudinal sectional vationalview of our mechanism taken substantially alongthe line 2-2 of Fig. 1; and Fig. 3 is a side elevational view of the shell member form combination with a valve stem andits guide, of
ing a part of our mechanism.
Similar characters of reference refer to similar parts and portions throughout the several" views of the drawing.
The conventional exhaust valve, designated A" in Fig. 1, comprises a head A1 which seats over tion of the stem entering the guide from view thereof; Fig. 2 is a partial plan partial elesaid guide, and a retainer the end of an exhaust port Bl formed in. the
cylinder block B. The exhaust port Bl curves I to one side and its bottom portion is provided;
with a valve guide C in alinement with the ex haust valve A'which protrudes upwardly into 0. the exhaust valve port. The guide 'C'receives the valve stem, designated A2,..of the valve. Our mechanism includes a shell memberl hav-* ing a cylindricalportion 1a adapted to fit over the protruding portion .of the valve guide C. 55 L This portion of the valve guide C may be machinedif necessary so that the shell 1 maybe pressed tightly thereon. The upper portion of the shell protrudes above the guide'C and termi nates in an inturned flange lb'leaving anopening 1c which loosely receives the valve stem'A2. The extended portion of the shell 1 forms with the ends of the valve guide C a small chamber 1d in which is positioned a collar member 2; The collar'member 2 is provided with a bore therethrough which s'nuglybut slidably receives the stem A2 of the valve; said collar fits loosely within the chamber ld. v Operation of our mechanism is as follows: Re-
,ciprocation of the valve and its stem causes the collar 2 tovibrate or reciprocate to a certain extent therewith. Oil which worksup the guide is delivered to the collar and is wiped thereby on the valve stem just above the guide but withinthe sill so that the'entire lengthof the valve stem within the guide maintains a lubricated condition. However,: excess carbon which may collect on the protruding portion ofthe valve I stem is continually worn'oif by the action of the collar, Furthermore, the shell 1 seals thepon direct contact with the hot exhaust gases. Thoughtwe have shown and described a particular construction, combination and arrangement of partsand portions, we do not wish 'to 9 be limited to this particular construction, combination and arrangement, but desire toinclude a collar slidably mounted on said valve stem above for, said collar supported fromsaid guide.
2. In an internal combustion engine having valves 'in which the stems thereof extend across v or through passages controlled by said valves and into guides intersecting said passages, the
combination with a valve, its stem and guide,
of a collar slidably mounted on said valve stem between the valve and guide, and a retainer for said collar supported from'said guide. 7
3. In a mechanism of the class described, the combination with a valve stem and its guide, of a collar slidably mounted on said valve stem above said guide, a shell continuing upwardly from said guide and surrounding said collar and.
combination with-a valve, its stem and guide, of
a collar slidably mounted on said valve stem between the valve and guide, a shell continuing upwardly from said guide and surrounding said collar and stem, and an inturned flange at the extremity of said shell for restraining said collar. 5. The combination with a valve, particularly the valve stem and its guide wherein the guide protrudes into the passage controlled by the head of said valve, of a cylindrical shell press fitted upon and extending beyond the protruding end of said guide, an inturned flange at the extremity of said shell, and a collar slidably mounted on said valve stem within said shell between said flange and the extremity of said guide.
