CHILDE HAROLD 'l/VILLS, OF MARYSVILLE, MICHIGAN."
OIL-FEEDING MIEANS.
Application filed November 12, 1920. Serial No'. 423,681.
the cam shaft of a hydrocarbon motor from the hollow interior of the shaft, and also` has particular advantages in automobile motors in which there is a change of level due to differences in grade.
The principal object of the invention is to provide for an equal distribution of oil from a hollow body toa plurality of parts to be lubricated at a uniform rate of feed, and in sufficient volume to provide proper lubrica-V Another object of the invention is to enable oil to be fed by pressure directly to the exterior faces of the valve operating cams of a hydro'cail'ion motor.
Another object of the invention is to insure a sufficient feed of oil to all the cams of an automobile motorwhen the vehicle is ascending or descending a grade.
TWith these objects and others in view, the invention is embodied in preferable form in the construction hereinafter described and illustrated in the accompanying drawing, in whirh- Figure l is a longitudinal central crosssect-ion of the cam sha-ft of a hydrocarbon vmotor and associated parts, and
F ig. 2 a cross-section taken through one of the cams.
In the lubrication of the cams of the cam shaft the oil is fed to the interior of the shaft, and passes through ducts therein to the outer surfaces of the cams. There is a tendency in the camshaft to throw the oil fed thereto toward the front of the shaft, thus causing an undue supply of oil to the front cams with a consequently diminished supply to the rear cams. This invention prevents the excessive feed to the front cams, and also prevents an excessive feed to the rear cams when thev automobile is ascending a hill.
The invention consists of a tube or a plurality of tubes mounted within the hollow cam shaft or similar body, and having a duct therethrough of less diameter than the total 4diameter of the channels leadingwv through the cams or other parts to be supi plied with oil from said tube, and into which tube the oil is conducted from the source of oil supply whereby the oil feed will be re# stricted and metered by the hole in the tube, and thus the feed regulated so as t-o maintain a uniform ysupply to all the cams and also a sufficient amount of oil for each cam -at all times.
Referring' 'to the drawings, l isa hollow cam shaft, and 2- cams carried thereby. These Canis have ducts 3 leading through the same to -the outer contact faces thereof. A role 4 admits oil under pressure to the interior of the hollow cam shaft which forms a part of the oiling system. The pressurev is supplied by a pump 5 shown dia-l grammatically. The invention is shown as applied to a cam shaft for the valves 6 of the four cylinders of one set of cylinders of a V- type, eight cylinder motor. Yllithin the hollow cam shaft are mounted two identical tubes 7, one located opposite each of the two sets of four cams at the forward and rear parts of the cam shaft. Each of these tubes is expanded at each end thereof at'8 so as to closely t the wall of the cam shaft to thereby cause the oil enteringthe center of;`
tube corresponds. The oil is forced into and through the tubes by the oil pressure. 10 is a small duct formed in the wall of the tube and leading to the annular space 9. The diameter of this duct is less than the total diameters of the ducts or channels 3 leading throughthe cams. The oil is thus restricted and metered byrthis single duct, and owing to its relatively small diameter the tube will always be sufliciently supplied with oil to furnish proper quantities to all the cams. This duct is preferably of the same diameter as each of the ducts through the cams. This metering of the oil by means of the tube also renders it possible to maintain suflicient pressure of the oil in the direct feed of oil to the cams from the pressure oil system as distinguished from those arrangements in which the cams are lubricated by splash or drip feed.
Having thus described my invention., what I claim is:
2. In combination with a hollow shaft, a
Vseries of me nbers to be lubricated having ducts communicating with the interior of said sha-ft, a tube mounted in said shaft to receive lubricant supplied to the shaft, said tube being spaced fromithe shaft opposite said ducts, and having oil passage mea-nsV therethrough leading to said space. y
3. ln combination'with a hollow shaft and parts having ducts communicating with the interior of said shaft for lubrication of said parts, a tube in said shaft adapted to receive the oil supplied to the latter, said tube having portions opposite said ducts spaced from the hollow shaft, and having an oil passage therethrough adapted to establish communication between the tube and said ducts.
t. ln combination with a hollow shaft and parts having ducts communicating with the interior of the shaft for lubrication, a tube in said shaft adapted to receive oil admitted to the shaft and spaced from the wall of the latter, `said tube having a single opening therethrough to admit oil from the tube to said space.
5. In combination with ahollow shaft and parts having` ducts communicating with the interior of said shaft for lubrication thereof, a tube in said shaft closely fitting said shaft at each end of the tube and spaced on the sha-ft intermediate said ends, means for admitting oil to said shaft and tube, and said tube having oilpassage means therethrough leading to said space, of less diameter than the total diameters of said ducts.
6. ln combination `with a hollow shaft and parts having ducts communicating with the interior of said shaft for lubrication, means for admitting oil to said shaft, a tube in said shaft open atits ends and closely fitting at said ends the wall of the shaft, said tube being spaced from the wall of the shaft intermediate said ends and 'having an opening therethrough communicating with said space, said opening being of approximatelyl the same diameter as one of said ducts.
7. in a hydrocarbon motor, the combina- 'ion with a hollow cam shaft, of pressure oil feed means communicating` with said shaft, cams on said shaft; duets leading from the interior of said shaft through said cams to the faces of the latter, and conduit means in the shaft through which the oil must passte the ducts having restricted passageway means therein of less diameter than the total diametrical area of thecam ducts.
8. ln a hydrocarbon motor, the combination of a hollow cam shaft, two series of cams thereon, means for admitting oil to said shaft between said two series of cams, a tube in said shaft at each side of said oil admitting opening having its ends extending beyond said cams and closely fitting the wall of the shaft and spaced from said wall intermediate said ends, said cams having ducts communicating with said space' and leading to the exterior faces of the cams, and an oil restricting opening leading through said tube to said space.
