OILING DEVICE Filed Nov. 5. 1923 S Mam Patented Au 11, 1925 ETD T FRANK SCI-IAFER, SR., 0F DULUTH, MINNESOTA.
OILING Application filed November To all whom it may concern:
Be it known that I, FRANK SoHArnn, Sn, acitizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Oiling Devices, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to oiling devices and has special reference to novel oiling means for crank pins of an internal combustion engine, the principal object being to provide a more efficient oiling device than heretofore known.
Other objects and advantages of the invention will appear in the further description thereof.
Referring to the accompanying drawing, forming part of this application, in which like reference characters indicate like parts:
Figure 1 is a side elevation of the lower end of an engine connecting rod, with the oiling device partly in section; and
Figure 2 is an enlarged transverse section on the line 22 of Figure 1, showing the boot in plan view.
1 represents the ordinary connecting rod, usually of substantially I-beam section, and 2 represents the oil well usually found in internal combustion engines into which the lower end of the connecting rod dips during its revolution receiving its lubrication by what is known as the splash system.
The inefficiency of this system of oiling the crank pin end of such connecting rods is well known to those versed in the art, and in carrying out my invention, a supply of oil is more positively provided by forming a boot leg 3 about the lower end of the DEVICE.
5, 1923. Serial No. 672,699.
run down the front edge of the rod as well as what may be running down the sides thereof. In this manner it is evident that the boot leg will be amply supplied with oil at all times during the operation of the engine.
To convey this oil from the boot leg to the upper half of the hearing I provide the vertically disposed hole 5 centrally of the web of the connecting rod and at the upper end of said hole is provided a transverse hole 6 through said web so that oil may readily pass from either side of the boot into the central hole; the usual oil grooves being provided in the upper brass of the bearing.
By this means it is obvious that a constant supply of oil is provided for the upper portion of the bearing, and any other convenient means for oiling the lower half of the bearing, such as the cup like orifice 7, may be provided as desired. An abundant supply of the lubricant is not only thus provided but the fact that the boot 3 has considerable capacity for holding oil, the same during the upward stroke of the connecting rod, will provide added pressure in its application to the bearing.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
The combination with the connecting rod of an internal combustion engine, of an oil receiving boot leg about the lower end of said rod, said boot being spaced from the face and sides of the rod for the purpose described, and means of communication between the bottom of the boot leg and the crank pin bearing of the connecting rod.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
FRANK SGI-IAFER, Sn.
