p I y P.H.GSMN@ CIRCULATING SYSTEM FOR INTERNAL COMBUSTION ENGINES Filed Feb. ll. i922 Application 'filed Ieisruory l, M532. Serial ."to. 535,65).

T0 all wfzom t may concern.'

Be it known that I, PALEMON H. Ges- Kms, e citizen of the United States, and e resident of Jacksonville, in the county of 5 Duval sndltcte of Florida, uive invented certain new and useful Improvements in Circulating Systems for internal-Combos! tion Engines, of Wliichl tile following is o specification.

This invention relates to intern-el combustion engines and more `rticularly to a. circulating system therefor Uu which water, or the lilo., is employed cooling medium.

The object of the invention is to provide adept/ed to perm t the liquid employed e cooling medium to be used when heated to :thigh decree by tire heat gencrezed in the associated engine; and with u minimum l 35 o circulatingsystein oi' tl'ie eisers. character LGSS so of the cooling medium by evaporation or otherwise.

@ther objects will hereinate. appear in the detailed description to follow invention is illustrated by of exsmpie in the accompanyingdrawing, in which ligure represents sectionu perspective View ot" tire forward portion of en automobile und showing tlie eppiicetion of 'the present invention. l

Referring to the drawings particu ieri E indicates generally un enqfine which in t lis instance is cest,- en bloc, although it is to be understood that my invention be applied to other types of engines. 'ille eugine E has its cylinder surroiuided the usuel cooling or Water jacket W and which. communicates with the manifold M .which is mounted upon said jacket.v At it is in dicfited u radiator which is provided with the usuel oep C threaded upon the neck it) of the radiator. Also at l1` there is iudis cated the usual drain tube, the upper end ot which is disposed within the neck l0 and its lower ond brought to a. position for charging Water or steam therefrom without injuring parts of the automobile. The

radiator has extending from its upper end e nipple i2 and from its lower end o nipple 13, seid nipples, in each instance, comnilumeeting with the interior of the radiator casting` in the usual manner.

in. the present instance, the free end oit the manifold M is connected through a ble tube or hose with the radiator nipple 13. The cooling or water jacket W ot the engine E Tues also secured. thereto tin-elbow l5 'which communicates with the interior of the Water jacket :it its one end und at its other end with u pump i. The pump I is preferably oi the rotary type and driven by e snail, Il, seid siiuft in turn carrying' upon its forward end u suitable pulley over Wiiicii muy pass a. belt i6, whereby the shaft S be driven 'from the crank shaft of tire associated engine E. The shaft S may be the usual means for driving the radiator o1 the automobile and simply extended to drive the uum l?. The fan is driven'by the belt itl und t e pulley 17. The extendirtioL-o of the siioft S for tiie pump may L vloci uy suitable bracket bearthe of pump P communicates u liose 20, the other end communicating with the interior of tie radiator R through the nipple The 2O muy loe secured to the nipo the inlet nozzle or nipple of lp by any conventional means, and

l vlo lios-e le may lieve its ends secured to he nienitld lvl und radiator nipple 13 in ililifll i lllllllf?! 'I iidjecen't the orwerd end of ru old ci there is threaded thereone feud ot o tube 2i which is ily or tire diameter shown, and the 1er end Hof s iol tube 1s connected Wit-l1 the l, 2 et uplorouimotely the point 22. The tube 2i es `ilishes communication between the .infiniiold the interior ot' the rz. etor'ut the points mentloned.

ff. he o'ieretion o the present circulating sys c, is i lows ii The waiter or other cooling;r

e tinu tile radiator R passes down- 'tt e arrows und is forced into the coolin Socket 'W of the engine E by the pump und from thence through the manifold M, hose 14:, and into the lower end of the radiator R. The water proceeds upwardly through the radiator and is thus cooled. By providing u pump for forcing the Water or other cooling medium through the cooling jacket of the engine insures that a circu lotion will elwuys be lied. Any steam which may be generated in the cooling jacket- W sud carried Ainto the lower part of the radiotor t rougir the hose lll will be entirely con- Aenscd dissipated before it reaches the nouer gluortion ol' tlie radiator and thus intliut eminimuni quantity of the cooling;

nieuwe will escape to the drain tube l1.

"olii through the hose 20 as indicated by its stated in the objects of the'present invention, the present circulating system permits the water or other cooling medium to reach a high degree of temperature and yet be utiliaed With certain advantages. As is Well known an en ine will operate at its highest eeiency w en its engine Walls are retained hot, but not to an excessive degree. It the water or other cooling medium was at its boiling point and steam could circulate Without Aharmful results the engine would operate at its best efficiency. In this instance when the water is brought to its boiling point, or above, steam will of course be generated and as the Water is passing from the manifold M the pressure of steam is relieved by the tube 2l. The steam passing through tube 2l will enter the radiator at a point beneath the Water therein and willfeie culate upwardly to the water and yibeo're reaching the nipple l2 will be inostiy con densed or dissipated and thus will not cause an overflow through the drain tube 11i I claim:

, In a circulating cooling system for intelvnal combustion engines, a radiator, a cooling jacket for the cylinder el the engine, a connection between the outlet of the eenling jacket and the bottoni of the radiator, a eennection between the inlet of the water jacket and the to of the radiator, and a bypass connection livetween the outlet of the cooling jacket and the radiator, said bypass communieatinfr With the radiator at a point below the outlet thereof.
