FORCED-FEED OILER.

Application filed August 23, 1921. Serial No. 494,597.

ing is a specification.

My invention relates to those 1 devices.

known as forced feed oilers' One object of the said invention is to provide an oiler of the charatcer indicated with which to automatically and; continuously supply oil to the valve stem and push rod ends of the rocker arms of internal combustion engines. Further objects are to provide device of the character indicated that will be simple .in form and construction, easily adaptable to all forms of engines, that has no workinp parts to wear loose or get out of order and that will be highly efiicient in its practical application.

In the drawings,-- 0 Figure 1 is a plan view of my invention as adaptable for six cylinder internal combustion engines.

Figure 2 is a side elevation of the same. Figure 3 is a cross-section on line 3-3-of Fi ure 2.

igure 4 is an end View, partly in section, showing the device in operative position on an engine.

Referring more particularly to the drawings. at 1 I show an oil carrying tube formed with curved ends and the sides equidistant and parallel with relation to the longitudinal axis thereof. the ends of the said tube being spaced a distance from each other and having connecting ells 2 and 3 secured thereto as shown. Connecting with said tube 1 through the medium of ells 2 and 3 are inlet and outlet pipes 4 and 5 respectively.

l\lounted upon and depending from oil carrying tube 1 and connecting therewith are a number of smaller, short tubes 6 spaced from each other and in the relative positions shown. The number of these tubes 6 varies with the type of engine and number of cylinderl of the same.

Secured tosaid tube 1 and along the longitudinal axes of tubes 6 are wires 7, the same being the supports for the'wicks 8 which fill the interior of tubes 6' and extend a distance below the same. The wicks 8 are held in operative relation to the parts to be oiled by means of strips 9 mounted upon tube 1, the same having openings 10 therein through which bolts 11, ofthe engine pass. p 7

In operation the oil is drawn from the crank-case 12 by means of oil pump 13 and is fo-rced through inlet pipe 4 into oil tube 1 and thence back into the crank-case through outlet pipe5. Thus the oil has a steady and continuous circulation, under a' slight pressure through the tube 1 where it comes into contact with wicks 8 at points 14. Said wicks 8, by means of their fibrous na-' ture, draw "the oil from tube 1 and when they become saturated the oildrips upon the parts to be lubricated, automatically and in uniform quantity.

In the present types of overhead valve constructed engines no provision is made for oiling the valve stem and push rod ends of the rocker arm, therefore the same is done with an oil can thus the oiling of the same is dependent entirely up'o-n manual labor, and consequently the said parts suffer from lack of sufiicient lubricant.

It is apparent however that with my invention in place these parts receive oil all the time they are operating and in sufiicient quantities to freely and efiiciently oil the same. The device is simple to construct as there are no working parts except the lubrieating pump-which is a part of every automobile engine and consequently nothing to beadjusted nor to wear out. The same is easily installed. Simply remove the rocker arm cover 15 and place the device in position on bolt 11. replace the cover and tighten up on the nut 16. which holds both the oiler and the cover securely in place.

It is to be understood, of course. that while I have herein shown and described one M I claim:

An oileicomprising an oil cai'rying tube having sides arranged parallel with the longitudinal axis thereof; the said tube having spaced inlet and discharge openings therein and a number of shorter tubes depending therefrom and connecting therewith and spaced in pairs a distance from the trans- JOSEPH H.
