VAIJVEGUIDE.
Application filed September -16, 1922." Seria1 No.588,622;
T0 all'whom it may concern Be 1tknown that I, \VILLIAM A. DrscH,:a
citizen of the United States, 'residingat' Chicago, in the county of Cook and State of Illinois, have-invented new and useful Im-- provements 1n Valve Gu1des,zof whlchv thefollowing is a specification; a
My invention relates to valve guides and more particularly to:such' as are applicable to 'reciprocatory' valves of the stem type,
employed in connection with thecylinders of internal combustion engines.
ing a guide suitably supported." One end of the-valvestem extends-into the'lntake and exhaust valve chamber andbecomes'covered with carbon, which :is carried into the guide as the=-valve"'rec1procates backhand forth thus subjecting the-bearing surfaces to undue wear, which, taken with unsuffi= cient lubricatloirthereof necessitates fre quent replacement of both' valve and guide:
" It is therefore the primary object of my in'-= vention to provide a guide of the character set forth which will serve" as a bearing surface for the valve stem, and will maintain the same free of carbon and in a thoroughly lubricated condition during its operation.
Another important obj ect of the invention is the provision of a valve of this kind which is adapted to receive and hold a considerable quantity of lubricant for communication to its bearing surface, the lubricant receiving portions of said guide being suppliable both manually and during the actuation of the engine.
The invention also has for ,an object to furnish a device of the kind stated which is highly eflicient in use, inexpensive of manufacture, and which will be applicable to all internal combustion engines of standard construction employing reciprocatory valves.
The above and other objects are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing, forming a part of this specification.
In the drawing:
Figure 1 is a view partly in section and partly in elevation illustrating the application'of'my improved 'valve guide to an internal combustion engine;
Fig.;:2 is-an elevation of--the guide re-' moved,- and Fig.6 is a central-longitudinal section through. the guide;
Referring specifically to the drawings-3'.
wherein like reference charactersdesignate' like parts throughout the several views, nu- -meral 10 :denotes a portion of the casing of an internal combustion-engine having an explosion chamber 11, a valve' chambe'r :12, 1 and a crank chamber: 13, the same: being:
usual springs :16 being furnished to returnprovidedwith intake and exhaust valve's of the puppet type shownat 14 and: operated inl the usual :manner" by means of: the cam shaft 1 '15 through the medium of push rods 16, the
theva'lve. Sinceth'e' engine,"perse, is'of a well known type' and forms no' part oft-he present 'invention, a further description 7 thereof is unnecessary. y r
The valve guicle' 17 which'for'm's the=sub'-'-"- ject matter-of my invention comprises 'a sleeve of cast iron'orother suitable bearing metal having"'a central bore 18 for the reception of the stem 14* ofthe' puppet valve 14. The guide is provided intermediate its ends with a shoulder 19 for determining the location of the guide with respect to its associated support upon the engine and, of course, this varies with different types of engines. Beneath the shoulder 19 the outer surface of the guide is formed with a number of undercut circumferential grooves 20 of considerable depth from which communication is had with the bore 18 through a plurality of obliquely disposed apertures 21 opening downwardly thereinto. In the engine illustrated, upon reciprocation of the piston within the explosion chamber 11, oil from the crank chamber 13 is carried upwardly through the aperture 22 in the partition 23 disposed between the crank chamber 13 and the portion 12 of the valve chamber, and is splashed into the undercut grooves 20 from which it seeps through the apertures 21 to the bore 18 for lubrication thereof. The reciprocation of the valve stem 14* serves to carry the oil upwardly to the bearing surface of the guide above the uppermost groove 20 thus eificiently lubricating the same and preventing overheating and undue wear. In engines of different types employing a different system of lubrication oil may be fed to the grooves 20 from an oil can, the grooves being of sufficient ca pacity to receive a considerable supply of lubricant.
The upper end of the valve guide l7 is provided with a chisel like edge 24 to re move any particles of carbon or other foreign matter clinging to the valve stem. An
' annular groove 19 in the outer surface of the valve guide adjacent and above the shoulder 19 may be provided for reception of a washer or gasket (not shown) to assure a tight fit between the guide and the engine. By my construction the effect of the lubricant supplied from the grooves 20 is not destroyed by the effect of carbon within the upper end of the guide 17. However, after long continued use the edge 24 becomes somewhat 'dullened and particles of carbon enter the bore of the guide. To provide for the removal of these particles the apertures 25 are furnished through which the carbon deposits are forced by the actuation of the valve, thus leaving the valve stem and the bore of the valve guide free of grit, and depositing the carbon particles in the valve chamber 12.
From the foregoing description read in connection with theaccoinpanying drawing, the novel features and advantages of my valve guide will be readily appreciated by those skilled in the art, and while 'I have described the preferred embodiment of the invention, it will be understood that various changes and modifications thereof may be made within the spirit and scope of the invention as claimed hereinafter.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: r
1. A valve guide for internal combustion engines comprising a tubular valve stem receiving body having the outer side thereof formed with a plurality of spaced circumferential lubricant receiving grooves, the upper and lower walls of which are inclined downwardly and inwardly, said tubular body being formed with openings inclined downwardly and inwardly from said grooves and opening into the bore of said body whereby the lubricant in said grooves may be supplied to the stem movable through said body, said body being provided above said grooves with a valve spring shoulder.
2. A valve guide for internal combustion engines comprising a tubular valve stem receiving body having the outer side thereof formed with an annular lubricant receiving groove, said tubular body being formed with openings inclined downwardly from .said groove and opening into the bore of said body'to supply the stem movable through said body with lubricant from said groove, the upper portion of said tubular body be ing bevelled to a sharp annular edge to engage and scrape the carbon from said stem, said tubular body being formed below said edge with a plurality of downwardlyand outwardly inclined openings for the discharge of the carbon on said valve stem.
In testimony whereof I affix my signature;
WILLIAM A. DISOH.
