OILING SYSTEM FOR litlil'Glhl'itS.V
Application filed April 11, 1922.
T 0 @ZZ whom. t may concern.'
Be it known that I, ELMnn TUTTLE, a citizen of the United States, andl resident of Antigo, in the county of Langlade and State of Wisconsin, have invented certain new and useful Improvements in Oiling System for Engines; and l do lrereby declare that the following is a full, cle-ar, and exact description thereof.
My invention refers to oiling systems for internal combustion engines such as disclosed in my application for Vpatent for internal combustion engines filed September 12, 1921, Serial No. 499,870.
The object of my present invent-ion is to provide a simple, economical and effective oiling system for the above referred to type of engine, which system includes cert-ain peculiarities of construction and arrange ment of parts` whereby .oil is introduced through a hollow cam sha-ft to all of the moving parts associated with the head of the engine, which parts include the valve cams and associated valve stems, bearings and driving gear connections.
With the above object in view, the invention consists in certain peculiarities of construction and combination of parts as are hereinafter fully set forth wit-h reference to the accompanying drawings and subse quently claimed.
In the drawings,
Figure 1 represents a fragmentary elevation of an engine equipped with an oiling system embodying` the features of my invention, the view being shown partly broken away and in section to more clearly illustrate details of construction pertaining` to the oiling mechanism, and
Figure 2, a longitudinal sectional View through the same, the section being indicated by line 2-2 of Figure 1.
Referring by characters to the drawings, 1 represents a movable series of cylinders, provided with the usual valve 2 and reciprocated valve stems 3. The upper ends of the valve stems are mounted in blocks 4t, which blocks are suit-ably secured with an engine head cast-ing 5. The head is also provided with end pillars 6, which terminate with split journal boxes 6. The split journal boxes constitute bearings for a shaft 7, which shaft carries actuating cams 8 Vfor the series of valve stems 3.
Motion is imparted to the cam shaft by a counter-shaft 9, which is Vsuitably sup- Serial No. 551,695.
ported at its upper end by a bracket 6, which extends from one.. of the pillars G. The counter-shaft carries a beveled gear l() that is meshed with a corresponding beveled gear 10, which latter beveled gear is secured to one end of thecam shaft.
All of the above referred to mechanism forms no part of my invention, which invention primarily refers to the oiling system and, as shown, the cam shaft is 'provided with a centrally disposed oil channel l1 which extends from end to end ofi the shaft.
As `shown,l in this eXemplificatio-n of my invention, the oil channel at one end of the shaft is beveled outwardly for the reception of the corresponding beveled end of a valve controlled oil feed pipe 12, the same being supported b-y an arm 12 which is extended upwardly froni one of the bearings of the shaft. Hence it will be seen that the oil feed pipe is held against rotation and a ground joint connection is effected between its end and the engaged beveled surface of the oil channel 11. Y
It is understood that the feed pipe is connected Vto a pump or other suitable means, whereby oil or grease is fed to the channel 11 under pressure.
The oil channel at the opposite end of the cam shaft is, in this instance, restricted with reference to the bore of the channel, the restricted passagebeing of sufficient area to permit a predetermined amount of oil to beV discharged from this end of the cam shaft, whereby it will be uniformly distributed upon the beveled teeth of the driving gear wheels 10` and'lO` and the discharged oil may also travel through a suitable duct through the gear wheel 10 to the bearing 6 therebelow.
The channel 11 is also provided with radial branch passages 13 which serves to distribute oil to the journal bores 6', and said shaft is also provided with similar radial passages 13', which passages pass through the low faces of the cams 8 and thus deliver oil or grease tothe engaged surfaces o-f the valve stem 3. Hence it will be seen that when the engine is in operation with each revolution of the cam shaft,
Aa predetermined quantity of oil is automatibeing understood that they oil feed passages and duct-s are of such proportions as to provide oil in sufficient quantities for pervfeotlubrication.
It is to be noted that by providing the restricted passage way adjacent the outer end of the earn shaft7 that the lubricant is prevented from freely owing directly through the Cain shaft Without supplying the transverse passages.
However, this restriction allows sufficient pressure to build up in the passage way of the cani shaft to discharge a suitable amount of lubricant int-o each of the transverse plas,- sage ways as wel-l as through the end yof the shaft. f
lVhile I have shown and described a simple exeinplitcation of my oiling systelguV in all of its details, it is understood that I may Vary the structural features withinthe knowledge of those skilled in the art.
I claim:
An oiling syst-ern for interna-1 combustion engines, having a lurality of cylinders, a head casting provi Ned with shaft bearings,
and valve stems reciproca-tively guided in the head Casting, a. eounterfshaft, a shaft journalled in the head bearings in beveled gear oonneetion with the counter-shaft, the last mentioned shaft having a longitudinal oil channel extending throughout its length and intersected at intervals by cross passages, cams carried by the `channel shaft through which certain of the cross passages extend, the earnsI being engageable with the ends of the valve stems, other cross passages ef the channel being in communication with the journalled bearings for said shaft, the said oil channel being adapted at one end to deliver lubricant to the driving' gears and having at such end a restricted passage way, and an oil feed pipe in coupling oonneetion with the other end of the channel shaft- In testimony that I claim the foregoing I have hereunto` set my hand at Antigo, in the county of Langlade and State of IVisconsin. Y
