WATER-CIRCULATING MEANS FOR INTERNAL-CQMBUSTION ENGINES.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application tiled July 29. 1913. Serial No. 781,759.

To all whom it may concern."

'Be it known that ,I, THOMAS C. Youno, a; citizen of the United States, residing at- Glendale, in the c'ounty of. Los Angeles,

State of California, have-invented a new and useful Improvement in Water-Circulating Means for Inte'imal-Combustwn Eni gines, of which thefo'llowing is a specificaindefinite time. I

tion. v Thisinvention relates toimprorements in the water circulating system used inv con nection witlr-gasolene engines, such system including aMater jacket for the, engine and a radiator connected to the water jacket.

The main object of the present invention is to conserve the water in such a'system, so that when the apparatus has once been filled with water it will remain full for an In connection with the radiator above referred to an overflow pipe isgenerally pro-' vided, which is open to the outer air, and through which water or steam escapes when the water in the-radiator is boiling. This results in loss of water from the apparatus and my invention provides for retaining this Water insuch manner that t is drawn back into the radiator when it cools.

Another objectof my-invention is to pre vent access of air. to the radiator, thereby preventing rusting of the radiator walls. In the operation of a. radiator having an open overflow-,I air'. is drawn intovthe radi-.' ator through this overflow whenever theradiator'cools, resulting in serious damage to the radiator by rusting, and my invention avoids this objectionable action by sealing the water circulating system from direct contact with the air. 7

Other'objects of my invention will appear hereinafter. g r

The accompanying drawings illustrate an embodiment of my invention and referring thereto: Figure] is a vertical section of an automobile provided "with my invention. Fig. 2 is a plan view of the water circulating system and the overflow receiver therefor.

The invention is shown as applied in connection with an automobile, but is capable of general application tointernal combus-' tion engines of the water cooled type.

1 designates the body or frame on which the engine 2 and radiator 3 aref mounted. Engine 2 is provided with the usual water jacket '2 having water circulating connections 4 and 5 with the radiator, the arrangement shown being of the thermosiphon type, whereinithe circulation is, effected automatically, without the .use'of a pump.

The radiator is provided at its top with the usual tiller cap' 6, and an exhaust or overflow pipe 8 opens'at its upperend'into the pace at the top of the radiator, for exambeneath the cap 6, said pipe.

ple, directly extending downwardly andthrough'the radiator wall. union 9, a pipe 10 leading to a receiver or tank ll, a sealing tube 12 being connected to the pipe 10 by a union 13 and extending down into tank or receiver 11, and opening at its lower end into said tank, near the bottom thereof Said receiver and the" connecting it with the radiator are l than the overflow outlet from-therad into said pipe, so that water'boilingover at said outlet will flow by gravity to th'e receiver. A vent pipe 14 communicates with the upper part of tank or receiver 11 and extends downwardly outside the tank. Tank 11 is provided with a filling opening normally closed by a screw plug 15'.

To this pipe is connected,-by a;

The operation is as follows: The water acket 2, radiator 3 and'receiver or tank I 11 are charged with water, andin the opera tion of the engine the water in thewater jacket becomes heated and flows automatically to the'radiator and from the radiator back to the miter-jacket. lVhenever the water in the radiator becomes hot enough to boil, steam and water'escape through the exhaust or overflow pipe 8, and are conducted by pipes 10 and 12 to the lowerpart of tank or receiver ll. Any steam so entering the tank 11 is condensed as it rises throughthe cold water in said tank. Thus the body ofwater in the tank or receiver 11 acts as a condensing means for the steam escaping from the radiator, when ,the latter becomes hot, and it also acts as a seal for preventing air from passing back through pipe 10 to the radiator when the latter cools On cooling of. the radiator any steam in the upper. part off the radiator becomes condensed and a vacuum is produced in the radiator at the top of the overflow pipe, with the result that water is drawn'from receiver or tank 11 back into the radiator, by reason of the deficiency of pressure in the radiator as compared with that in the tank ll. Thus the apparatus is maintained in charged condition, and no water is lost to thesystem as a whole.

Thepiie atmo that w on a vacuum is produced imthe radi: etor, the atmospheric pressure in the tank .11 forces the water back intothe radiatoii' end on the other hand, it acts as a safety rent, to, permit the escape of any steam which might be generated in the tank 11 by reason of excessive heating of the radiator.

"What I claim is: W 1.; The combination w. th he water jacket of internal combustion engine, and a radietor connected to said water ac ct, rovided Tith a filler cap and with an over ow outlet'helowsaid 'cap,; of a. receiver for containipg g. body of water, said receiver being open to communication with the atmosphere, and overflow pipe leading from said overflow 1 t meintains connection from the on let of. said radiator and communicating Viththe receiver below the level of the water said overflow pipe and receiver belower than the overflow outlet from the radiator, to allow flow of water from said outlet to the receiver by ravity, to receive the overflow and steam rom the radiator when the water therein boils, and to feed the overflow and condensed steam back to the radiator when it cools. I

2. The combination with the water. jacket of an internal combustion engine, and a reere toptheinterior of tenk-lil, so

diator-conneeted'to said water iackct, provided with a filler cap and with an overflow outlet'below said cap, of a receiver for containinga body of water, and an overflow pipe leading from said overflow outlet of said radiator, and opening into the body of water in the receiver, said receiver being provided with a vent at its upper portion, and said overflow pipe and receiver being lower than the outlet from the radiator, to allow flow of water from the said outlet to the receiver by gravity.

3. The combination with the water circulating system for an internal combustion engme of an overflow pipe therefor, and a receiver open to atmos nected to saidover discharge from said pipe when the water in the system boils and to retain the discharge and feed itlatter cools, said overflow pipe and receiver being lower than the overflow outlet'from the water circulating system to said overflow 9 50W outlet to the receiver by gravity.
