CHARLES WHITE, or GLEN covE, NEW YORK.

INTERNAL-COMBUSTION ENGINE.

To all whom it may comm-11 Be it known that I. CHARLE lVHrrE, a citizen of the United States, and a resident of the town of Glen Cove, county of Nassau,

and State of New York, have invented a new and useful Improvement in Internal- Combustion Engines, of which the following is a specification, reference being had to the accompanying drawing.

As is well known, the accumulationof carbon, and gummcd oil iibout the intake and exhaust valves and the valve stems of internalcombustion engines is a source of much trouble and expense in the running of automobiles. It is the purpose, therefore, of this invention to provide inexpensive and easily operated means whereby the carbon and gummed oil may be efiiciently and inex- ,pensively removed from the parts referred to and their lubrication easily and quickly effected.

The figure of the drawing is a vertical sectionnl view of a portion of an automobile cylinder, showing an intake valve and one form of my invention applied thereto.

In the drawing, 1 represents a part of the inner wall of a cylinder, 2, 2, the water jacket passages, 3 one of the intake valves,- 4 the stem therefor, 5 the usual spring, 6 the rod which extending downwardly engages with the cams or eccentrics, 7 a nip ple which is threaded into the outer wall of a part of the water jacket, as shown, and is tightly entered into an opening 8 made in the bored stem guide part of the casting. 9 is a coupling nut whereby the ferrule 10 of a pipe 11. which may be rigid, asof metal,

'or flexible, as of rubber, or other suitable material, as preferred, may be tightly clamped to the exposed end of the nipple, 7. 12 is a small reservoir with which the opposite end 13. of the pipe engages. 14 is a waste plug to draw oil the contents of the reservoir 12. 15 is the filling opening for the reservoir. 16 is a cap adapted to seal the opening 15. 17 is a pipe which enters the upper end of the reservoir and 18 is an air pump of any suitable construction.

The operation is as follows: L,

Kerosene, or equivalent carbon-- and gummed oil cutting and reinovi liquid is first ut into the reservoir and 6 ca placed in position." gummed oil accumulate upon the valve, its seat or stem, then a few strokes of the air pump 18 will generate air pressure upon Specification of Letters Patent.

the to of the kerosene, which will be forced -from he'rescrvoir through the pipe 11 and nipple 7 against, the side of the valve stem 4 and o wing'to the permeative character of kerosene, or its equivalent, it will be dis h of the valve stem, and a,- portion carrie upwardly and spread lateral lyover-the under side of the valve 3, so as to ,cut and'remove the objec- -tionable deposits upon the valve and its seat. The amount of kerosene thus injected will depend upon the desires of the chaufi'eur: or operator, which obviously will depend uponthe foulnessand size of the parts. The carbon and g'ummed oil thus disintegrated and washed 0; shoved. aside will partly move downwardly along the stem, and dro through the spring 5, to an unobjectionab 0 place, from w ich it may be periodically i'emoved, and that which comes from the valve and its seat will-drop into the water jacket or manifold its the case may be, fromwhich il: .also' will be eriodically removed.

It will be un erstood that although I illu's- 3 tratc the invention as applied to a single cylinder, that there may be as many pipes 11 as there are cylinders, or that a single pipe 11 may connect the reservoir with a suitable crosshead or manifold pipe, frontwhich individual connections with the several cylinders may be made. It willv of course be unnecessary to illustrate these details because they are elementary in such mechanism. Moreover they will vary when used in conjunction with en ines of differ-- ing constructions. Also it wi 1 be noted that the nipples may be so located as to discharge upon any referred part of the valve stem, or the va ve, or its sent, and that 9 there may be more thanone nipple dis- It will also., note that the reservoir and pump m located at any convenient place upo car, and if desired. the um plungeir be manipulated rroin t e aufl'eurs sea I prefer to arrange the hi pie 7 titan 1111; ward angle as illustrated, .so'that the tend sene may be to impel it upwardl {so that; it may miore surely distribute itsell upon all parts oi the stem and valve. Gravity-will tend to spread it in the opposite direction. "-5 The apparatus describedjxrgfllustrated shows one form only in whi' y'mvention 11''? may be embodied and many departures therefrom may be made and till'the es seu ,v V

tials of the invention be retained. I therefore do not limit myself to such details.

I claim:

In combination with an internal combustion engine provided with a valve which coinn'iunicates with the interior of the cylinder, devices for removing carbon and. the like from the valve and its stem comprising a reservoir for kerosene or similar carbonremoving material, having a sealing device, an air pump discharging into the u per part c. the reservoir and a pipe exten ing from the lowerp'art of the reservoir and discharg' ing against the stem of the valve.

2. In combination with an internal combustion engine provided with a valve which communicates with the interior of the cylinder, devices for removing carbon and the like from the valve and its stem comprising a reservoir for kerosene or similar carbonremoving material, having a sealing device at its upper part anda draw-off plug at its bottom, an air pump discharging into the upper part of the reservoir and a pipe exzending from the lower part of the reservoir to and through the cylinder structure and discharging upon the stem of the valve.

3. In combination with an internal combustion engine provided with a valve which communicates with the interior of the cylinder, devices for removing carbon and the like from the valve and its stem, comprising a reservoir for kerosene or similar carbonremoving material, having a filling device at its upper part and means to close the filling device air-tight, an air pump adapted to pump air into the uppergiart of the reservoir and a pipe extending rom its lower parh to and through the cylinder structure and discharging upon the stem of the valve.

4. In combination with an internal combustion engine having a cylinder and a stemmed valve connecting therewith, a reservoir provided with means whereby it may be filled with kerosene or other carbon-removing material and means to close the filling opening air-tight, means to generate air pressure upon the top of the contents of the reservoir and a pipe extending from the lower part of the reservoir to the cylinder structure, the cylinder structure being provided with an opening in continuation of the said pipe extending at an upward angle and discharging upon the stem of the valve.
