DEVICE FOR OILING VALVE STEMS IN INTERNAL-COMBUSTION ENGINES BY MEANS or FORCE FEED.

Application filed August 6, 1926. Serial No; 127,642.

This invention relates to oiling devices, andits general object is to provide an oiling device that is primarily designed for lubricating the stems of valves of internal com- -bustion engines. I

A further object of the invention is to provide an oiling device for the stems of valves of internal combustion engines, that is adapted to be disposed in communication with the oil pressure line of an engine and includes manually operated means for controlling the flow of lubricant to the stems.

Another object of the invention is to provide an oiling device for the stems of valves of an internal combustion engine that supplies the lubricant between the stems and their guides, with the result the stems will be properly lubricated so as to perform their intended function in aneificient manner.

A still further object of the invention is to provide an oiling device for the stems of valves-of an internal combustion engine, that is extremely simple in construction, inexpensive to manufacture and install, and eflicient in operation 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 drawings and specifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 illustrates our one type of internal combustion engine.

and t e wicks therefor.

Figure 7 is a vertical sectional view taken through the valve for controlling the lubri- 5 cant to the stems.

device applied to tional view taken through a portion of the in any well knownmanner in the block are 1 stem guides 1 that have their lower ends tapered and disposed adjacent the lower ends are longitudinally disposed slots 2 that extend through the guides and are arranged in diametrically opposed relation with respect to each other. i

Each of the slots have their upper and lower walls disposed in converging relation with respect to each other and are adapted to receive wicks 3 that are substantially wedgeshape as shown in Figure 6 for the purpose of fitting the slots 2 as will be apparent; The wicks 3 are of a size to engage the stems of the valves as shown in Figure 3 and may be formedfrom felt or other Well known absorbing material.

. Asubstantially cup-shaped reservoir 4 is rovided for each guide and surrounds the atter as clearly shown in Figures 3 and 4. Formed with the cup-shaped reservoirs 4and depending therefrom are projections 5 which are adapted to receive the upper ends of the coil. springs B, and these reservoirs 4 take the place of the'usual abutment means for the springs.

Arranged in the cup-shaped reservoirs 4 are disks 6 of absorbent material that surround the guides and the reservoirsare disosed on the uides in a manner whereby the isks of absor ent material engage'the wicks 3 whereby capillary action will cause the lubricant to pass from the disksfi to the wicks 3 as will be apparent.

Each of the reservoirs are provided with aninclined bore 7 extending through the walls thereof for communication with the inner side of the reservoirs as best shown in Figure 35 and these inclined bores have their ipe lines 8 which have their outer ends ormed or secured with a pipe line 9 for communication therewith in any well known.

manner, and this .pipe line supplies the lubricant to the-reservoirs through the mediuni of the bores and thesbr anch'pipe lines 8 as will be apparent.

I The pipe lme 9 has one of its ends closed by a plug or the like, while its oppositeend is arranged in communication with a needle Valve that includes an elbow body 10 having a seat therein to accommodate thetapered end of the stemll which is provided with a serrated head 12'whereby the stem can be adjusted with respect toits seat as will be apparent.- Disposed in communication with the needle valve is the oilpressure pipe line 13 of the lubricating system of the engine. a

From the above description and disclosure of the drawings, it will be obvious that We have-provided an oiling device for the stems of the valves of internal combustion engines,

that is manuall controlled through the instrumentality o the needle valve as shown in Figures 1 and 7, with the result the pressure of lubricant to the valve can be regulated as desired, and by employing the cup-shaped reservoirs having projections thereon, these reservoirs not only act as such but also act as abutments for the upper ends .of the coil springs. By employing the wicks and disks of absorbing material in the manner set forth,

' with the means of supplying lubricant tothe 'valve in the pipe line.

disks, our device will perform its intended functiop in an eflicient manner for a prolonged period of time and with minimum attention.

It is thought from the foregoing description that'the advantages and. novel features of our invention will be readily apparent.

' We desire it to be understood that we 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.

In an oiling device, the combination with a' valve of an internal combustion engine and its spring, of a guide for the stem of said valve and being formed with slots extending therethrough, a wick in each slot and being engag'eable with said stem, a substantially cu -shaped reservoir surrounding the guide,
