UNITED, STATES PATENT OFFICE.
WILLIAM r. Awn, or CHICAGG, ILLINOIS.
vim: GUIDE.
Application filed Septemberfll, 1922. Serial No. 589,580.
To, an whom it may" concern: a 1 Be it known that I, WILLIAM FJAWE, a citizen oi the'United States, residingat Chicago, in the countyof Cook and State of Illinois, have invented a certain new and .useful Improvement in Valve vGuides, of
which the following is man, clear, concise, and exact description, reference beinghad to the'acc ompanying drawing, forming a part of this specification.
My invention relates to valve guides, and more specifically to: poppet valve guides,
' which are lubricated by the splash of oil of apor'tion of an internal combustion endrawing wherein from the crank case an internal combustion engine by means of reservoirs or'pockets on the periphery of the valve, and ducts leading from the reservoirs to the inner bearing surfaces. 1 The chief object. of myinvention is to improve the-lubrication of sucha valve. guide by insuring a more even flow of lubricant intothese pockets "by means of a layer of fclt like material lying aroundlthe pockets and serving, by' capillary attraction and otherwise, to feed such oil as comes in con-' tact with it to the pockets.
A still furtl'ier object of my invention is, by aisim lar arrangement'of felt-like material, to strain theoilfof'such particles of 'loreign matter as mayhave accumulated in it in its previous use. j
Other advantages of my invention will appear from the description which follows, in which I shall refer to the accompanying transverse vertical section Figure 1 is a gine showing the guide of my invention adapted to a downwardly seating poppet valve;
Figure 2 is valve guide; 1
Figure 3 is a longitudinal-section of the guide, and,
Figure 4 is a transverse vertical section taken Iuponthe line s r-4 of "Figure 3.
an elevational view' of the Similar characters of reference refer to similar parts throughout jthe several views.
I have indicated in the drawing a downwardly seating poppet valve 11 which reciprocates within the bore 12 of a valve guide 13, which "issupported in a suitable aperture in the-cylinder casting- That por tion of the valve guide which lies below the limiting shoulder 14, it-will be seen, lies in {hat portion-0f the cylinder casting outside 'stem, I
WVere the felt sleeve 17 omitted, the lubriof the gas port 15, access being had between this portion of thevalve' stern and the crank case by an aperture 16 through which the lubricant .in the crank case is splashed by the rapid rotation of the crank shaft, with the result that lubricant will fall upon the lower end of the'valve guide and upon the ad oining surfaces of the cylinder casting,
whence it gravitates downwardly to a sleeve 17 consisting of a layer of felt-like material which surrounds the lower exposed portion of the guide. This portion-of the guide, it will be observed, is provided with a plurality of vertically spaced annular reservoirs or pockets l8 havinginwardly inclined or conically conformed lowersurfaces, from which a plurality of small ducts 19 leads through the remaining thickness of the shell of the guide to the bore 12 which forms the bearing surface for the reciprocating valve cant would run down the sides of the valve stem and enter the reservoirs 18, from which the lubricantpwould be fed rather rapidly into the bearing surface becauseitis impossible to] prov de the guides w1thrlucts19 which are sufficiently small in area, for to do so would cause frequent clogging of. the ducts by small particles in the relatively be left without the most efficient lubrication during long periods of idling of the engine.
The provision of the felt sleeve 17 overcomes both of these objects in that the oil which enters the reservoir 18 is'strained through the line pores of the felt with the result that the use of ducts 19' of smaller area becomes practicable, and in that the felt tends to hold in its pores a considerable amount of lubricant which it releases gradually into the reservoirs 18. In this way,
vthe feed fromthe reservoirs into the bearing surfaces is made gradual and constant, and
the supply oflnbricant t0 the reservoirs is r maintained at a relatively constant'amounte An occasional speeding of the.engine,it will be seen, will quickly resaturate the i felt sleeve 17 with lubricant. It is also to be noted that the felt sleeve 17 gathers oil from a larger area on the guide than would be gathered by the reservoirslS without the use of the sleeve.
I have. found in practice that as the lower end of the valve guide, as shown in Fig. 1, is insulated from the .heat of the exhaustport 15 by'the water jacket, there is no tendency for the ."lelt sleeve 17 to burn, although it is not made of non-combustible mate ial.
.llavingtlius described my invention, what I claim is: l
l. A valve guide comprising a bearing surface for a valve stem, a peripheral pocket for the reception of lubricant, a duct leading from adjacent the bottom of said pocket to said bearing, and a layer of felt secured to said guide and overlying said pocketfor bringing to said pocket such lubricant as is splashed ontosaid guide.
2. A valve guide comprising an inner bearing surface for a valve stem, vertically spaced pockets on the periphery of said guidevfor the collection of lubricant, ducts feeding lubricant from said pockets to said bearing surface, and a layer of felt-like material lying around a portion of said guide and'covering said pockets for the purpose of supplying lubricant which finds its way to the surfaces of said material to said peckets, saidematerial also straining said lubricant.
3. rAfi valve'guideconrprising a bearing for the-stem ot' a reciprocating valve, said guide being provided with a plurality of long-i tudina-lly spaced annular peripheral recesses for the reception of lubricant, the bottoms of .whichr cesses are inwardly inclined, annular portions of said guide separating said recesses from said bearing surface, ducts leading through said annular portion from said recesses to said-bearing surface, and a sleeve of felt-like material lying around said guide and eovrin'g said recesses lor bring ing oil to saidirecesses.
at. A valve guide comprising a bearing surface fora valve'ste n, arperipheral pocketfor thecollection oflubr-icant, a duct leading from said pocket to said bearing surf cc, and alayer of felt-like material overlyingsaid pocket for supplying lubricant to said pocket.
A valve guide for motors comprising a cylindrical bearing member having an internal bearing surface, a duct through the wall of said member for carrying oil to said surface, and a felt-like absorbent member surrounding a portion or" said cylindrical hearing member and adapted to receive oil in the form of mist or splash and to retain a portion of said oil at the entrance to said duet, whence it may pass gradually to the internal bearing surface, the fibrous character of said felt-like material serving to strain'out the coarser particles of carbon and grit from said oil.
In witness whereof, hereunto subscribe my name this 15th da) of September, 1022.
