LUBBICATOR FOR INTERMEDIATE GEARING.

Application filed November 22, 1921. Serial No. 517,036.

Gearing, of which the following is a full,

clear, and exact description.

. The present invention relates to new and useful improvements in intermediate driving gears for accessory shafts of motor vehicle motors, and it pertains more particularly to a means for lubricating the driving gears.

It is one of the objects of the invention to provide a new and improved means for feeding a lubricant to the driving gears of the accessory shafts. V g

It isa furtherobject of the invention to so construct .this lubricant-feeding means that its action will be constant during the operation of the motor.

With the above and other objects in view,

reference is had to the accompanyingdraw+ ings, in which the figure is a detail sectional viewof the forward portion of an internal combustion motor. I

Referring, moreparticularly to the drawings, the reference character 5 designates the upper wall of the crank case of the motor and mounted in an opening 6 formed therein is a housing or the like 7. Mounted in the lower open center of the housing 7 is an anti-friction bearing 8, and said antifriction bearing 8 serves as the centering means or support for a vertically extending shaft 9. Secured to the lower end of this shaft 9, is a bevel gear 10, and said bevel gear 10 meshes with a bevel gear 11, which latter is carried by the motor crank shaft and is shown broken away in the drawings.

Extending vertically from the housing 7 is a tubular housing 12, and mounted in said tubular housing 12 is a shaft 13, which is connected to the shaft 9 as shown. This shaft 18 extends vertically of the engine and serves as the means for driving the cam shaft thereof, which latter, however is not shown.

The reference character 14 designates the accessory shaft, and mounted on said accessory shaft is a gear 15. This accessory shaft 14 and gear 15 are mounted ina suitable housing 16. The shaft 14: and the gear 15 are driven by means of a gear 17 and said gear 17 is connected. to a other suitable means 19. Meshing with the gearlS is a gear 20, and said gear 20. is mounted upon the crank shaft of the motor in such a manne'r as to rotate therewith and.

dear 18 by or v furnish the driving power for the gear 18.

.The heretofore mentioned gears 17 and 18 are provided with a bushing 21, and said gears are mounted to rotate upon a hollow bolt or pin 22 secured inthe lower portion of the housing 16; This hollow bolt 22 has a passage 23 extending longitudinally thereof, and branching off from said'passage 23 and extending through the side walls of the hollow bolt 22 are passages 24, the bolt be,-

ing cut away as indicatedby the reference character 25 to provide a space between the hollow bolt 22 and the bushing 21.- Ata point adjacent the openend of the passage '23, "the housing? is'provided withanopening 30, and carried by the shaft 13 at a point adjacent the opening 30, is a dished member 31. This dished member 31 is carried by the shaft 13 and is adapted torotate therewith.

The device operatesin the following manner:

i The lubricant is fed in any suitable manner (not shown) to the cam shaft housing (not shown but with which the housing '12 communicates.) As the lubricant feeds through the cam shaft housing into the housing 12, the lubricant will pass downwardly of the housing 12 and downwardly of the shaft 18. As the lubricant passes down the housing 12 and the shaft 13, it is caught by the dished member 31, and owing to the rotation of the shaft 13 and the dished member 31, the lubricant is thrown by centrifugal action from the dished member 31 through the opening 30 in the housing 7 and into the passage 23 of the hollow bolt 22. From the passage 23, the lubricant passes through the passages 24: to the space formed by the cut-out portion 25, to lubricate the gears 17 and 18 carried by the bushing 21. 7

From the foregoing it is apparent that by the construction shown in the present illustration, the intermediate driving gears of the accessory shaft will be constantly lubricated during the operation of the motor and that the lubricant is constantly fed to the intermediate gears by centrifugal ac tion.

I claim:

11 A lubricating means for intermediate gearing comprising a hollow bolt upon whlchthe intermediate gearing is mounted,

said hollow bolt having passages extending- 2. A mechanism of the class described comprising a housing, a shaft mounted in said housing, means for driving said shaft, a dished member carried by said shaft internally of the housing, an intermediate gearing, a hollow bolt for supporting said intermediate gearing, said hollow bolt alining with an opening in the housing and adapted to receive lubricant projected by the: centrifugal action of the dished member through the hollow opening of the bolt.

3; A device of the character described comprising in combination, an accessory shaft, a cam shaft driving shaft, acrank shaft, an intermediate gearing for driving the accessory shaft from the crank shaft, a support for said inter-mediate gearing, and means carried by the cam shaft driving shaft for projecting lubricant to the inter' mediate gearing support to lubricate the intermediate gearing.

4- A device of the character described comprising in combination, an accessory shaft, a cam shaft driving shaft, a crank shaft, an intermediate gearing for driving the accessory shaft from the crank shaft, a support for said intermediate gearing, and centrifugal means carried, by the cam shaft driving shaft for projecting lubricant to the support of the intermediate gearing support to lubricate the intermediate gearing.

5. A mechanism of the class described comprising in combination, an accessory shaft, a crank shaft, a cam shaft driving shaft, a housing for said cam shaft driving shaft, said housing having an opening, intermediate gearing; for driving the accessory shaft, a support for the intermediategear-ing, saidsupport comprising a hollow bolt having its open end in alinement with the opening in the housing ofthe cam shaft,

driving shaft, and means for projecting lubricant through the opening of the cam shaft driving shaft housing into the hollow bolt for lubricating the intermediate gearmg.

6. A mechanismof the class described comprising in. combination, an accessory shaft, a crank shaft, a cam shaft. driving shaft, a housing forsaid cam shaft driving shaft, said housing having an opening, intermediate gearing for. driving the access sory shaft, a support for the intermediate gearing, said support comprising a hollow bolt having its open end in alinement with the opening in the housing of the camshaft driving shaft, and centrifugal means carried by the cam shaft driving shaft for projecting lubricant throughthe opening of the cam shaft. driving shafthou-sing into the hollow bolt to lubricate the intermediate gearing,

7 A lubricating means-for gearing comprising a hollow bolt having an exposed open end and forminga support for said gearing, and centrifugal means-in alinement with the exposed open end of said bolt for supplying lubricant to said hollowfbolt VICTOR WV. PAGE.
