Description

Patented Septt 7, 1926.
HAROLD o. GoonBaAKn, or EAST str.Y LoUIs, I'LLINoIs.
VALVE-STEM QILER.
Application led .Tune 22, r1925. Serial No.'38,812.
This invention relates toy oilers for valve stems of internal combustion engines. i
The object of the invention is to provide an oiling system constructed so as to ensure pertect'valve action and to prevent trequent and expensive valve and valve guide replacement. g
Another object of the inventionv is to provide an oiling system of this character io which may be applied to all types except a vertical valve in head motor including sleeve valves, marine and stationary engines also tractors. With the foregoing and other obyects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinatter described and claimed, it being understood that changes in the precise embodiment oit the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings Figure l represents -a side elevation of an engine equipped with this improved oiling system, portions being broken out to show 'the application of the oiler;
Figure 2 is an enlarged detail sectional with this improved oiler; and
Figure 3 is a, horizontall section taken on the line 3-3 of Figure 2. v v
Y It has been proven that 7 5% of the valve trouble in internal combustion engines is due to the sticking of valve stems caused by v Ypressure oiling systems so that-.this system may be added Without'the expense` of add-A ing a pump which is necessary to lensure an even pressure of the oil.
The invention is shown applied tothe engine of aV Dodge carfwliich is shownat l and which has eight valves one ot-'which is shown at y2.k This valve' is equipped with the usual valve stem 3 vmounted to reciprocate in a' cylindrical valve guide 4.- Each valve guide 4 is equippedl atl its upper end about three-eighths of an inch below the top ywith an oil pocket 5 which isl about oneview showingy the valve stem guide equippedv It is .to overcome these ob-v eighth of an inch wide and from which leads a spiral groove 6, said groove being about one-sixteenth of an inch deep. Oil is discharged into the'poclets 5 oit' each pair of guides 4, through a tube 7 The tubes 7 are connected by a coupling 8 with a larger in outer diameter.y The tube 9' is connected by a coupling lO with a larger tube 11 which is about threefeighths of an inch inV outer diameterl and is connected by a coupling l2 with a pipel which leads to a gear pump not shown. The gear pump operates to drive the oil under pressure through the system and ensures a continuous feed to the grooves contained in the valvev guides.
.An oil drainl is arranged between each sure system all that is necessary is to connect up said system through the pipe 13 with the pipes l1, 9 and 7 which discharge .into the pocliet 5 of the valve stem guide and thus supply lubricant to this stein which;
will freely reciprocate in said guides with out danger of binding or sticking andthus ensures proper seating of the valve.
I claim Y y The combination with the frame of an internal combustion engine, of aV tubular guide mounted in the frame, a poppet valve including a stein mounted to reciprocate in the guide, and a tube extended throughV a' portion of the frame Aand into the guide, theV guide being supplied with an internal circumterentialoil pocket withwliich the inner end of thetubecommunicates, and theV guide having an internal groove `which eX- tends spirallyv down Vfrom the ,oil 'pocket tube 9 whichis about one-fourth ot an inch i through thev lower end of the guide, the 'f Y vspiral groovev opening laterally into the guide throughout the length of the groove,
and said groove being shallower than the joli pocket.'
In `testimony that I-claim theforegr'iingv as my own, I have vhereto -afxedmy signa` ture. Y Y l HAROLDV C. GOODXBRAKE.
