Description

wymzs A g 1932- J. 5. LE FEVRE VALVE OILER Filed Sept. 9. 1930 ATTORNEY Patented Aug. 16, 1932 UNl'i'E TATES PATENT; on on 1 JOHN S. LE FEVREOF EL CENTRO, CALIFORNIA, ASSIGNOR OF ONE-FOURTH. T WALTER L. SCOTT AND ONE-FOURTH 'IO ARNOLD O. KLEIN} BOTH OF EL GENTRQOALIFORNLA.
VALVE OILER Application filed September 9, 1930. Serial No. 480,729.,
This invention relates to'lubrication, and its general object is to provide a device for lubricating the valve stems of an overhead valve engine, in a manner whereby sufficient 5 oil will be provided for the stems as well as between the latter and the rocker arms, to
insure quiet and efficient operation of these parts at all times.
A further object of the invention is to provide an indicating device for the purpose set forth, that can be attached to the rocker arms of an overhead valve engine through the medium of the usual cap screws now employed, with the result no change will have to be made in the rocker arm'mechanism to install my attachments thereto, and the attachments can be installed in an easy and expeditious manner with very little eifort.
Another object of the invention is to provicle a lubricating device for the valve stems of an overhead valve engine, that is simple in construction, inexpensive to manufacture and install and extremely efficient in opera tion and service.
. This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specificaL ly pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a top plan view illustrating the application of my lubricating device to the rocker arm mechanism of a valve and head engine.
Figure 2 is a sectional view taken approximately on line 22 of Figure 1 looking in the direction of the arrows.
Figure 3 is a perspective view of the lubrieating device per se.
Referring to the drawing in detail, the letter A indicates the rocker arm of a type now employed on certain kinds of overhead valve engines, B the cap screw for securing the rocker arm mechanism to the cylinder head, 0 and-VG the valve stem which is engaged by the free end of the rocker arm as clearly shown 1 in Figure 2 of the drawing. The aforementioned elements do not constitute anypart of the present invention and' are merely disclosed to properly illustrate the application and use of my invention which includes a cup 1 offa size to engage the top of the bear ing for the rocker arm shaft as clearly shown in Figure 2, and it will be obvious that one of my lubricating devices is employed for each pair of rocker arms and co-operating valve stems as shown in Figure 1. The cup 1 is relatively shallow and has an opening 2 formed in the top thereof for the purpose of V accommodating the cap screw which is utilized for securing the devices with respect to the rocker arm mechanism.
Secured to the cup 1 and extending in divergent relation with respect thereto are conduits 3 which are disposed in parallelism and have their free portions curved to a degree whereby the outer or free ends thereof are disposed in close proximity to the free endsof the rocker arms as best shown in Figure 2.
The conduits 3 are of course hollow and are disposed in communication with the interior of the cup, while their free ends are provided with drain openings 4 disposed upon the lower side thereof so. that oil will drip provided a lubricating device that will amply lubricate the valve stems of an overhead valve engine so as to'not only provide for the efl'icientoperation of the valve, but due to the fact that oil will accumulate between the rocker arms and stems, a cushion will be provided which will eliminate all noise which is generally caused by the tapping of the rocker arm upon the valve stems.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts,
provided that such changes fall, within the scope of the appended claim.
What I claim is: 7
A lubricating device for the valve stems of an overhead valve engine, comprising a cup having an opening therein adapted to have 10 passed therethrough the cap screw of the rocker arm mechanism of the engine, said-cup being secured to the mechanism to receive oil v from the rocker arm shaft, a pair of diverging conduits in communication with said cup 7 and curved for a portion of their length to follow the curvatureof the rocker arms of said mechanism, said conduits terminating in close proximity to the free ends of the rocker arms and being provided with openings in their lower ends for the'disposal of oil' upon the top .ofsaid free ends. 7 g
g In testimony whereof I affix my signature. JOHN S. LE FEVRE.
