HEATING SYSTEM FOR LIQUID 'CIRCULATING COOLING SYSTEMS Filed Aug. 9, 1928 INVENTOR Patented Nov. 7, 1933 I s lsssgzsr I I I HEATING SYSTEM FOR QUID CIRCULAT- I iNG COOLING SYSTEMS I I 7 t Rosa'New York,N. Y. t App ic Au ust 9, 1928; SerialNo. 298,434 I II 9 Claims. (013123-174) I I p This invention refers to internal combustion motors and more particularly to that class having a liquid circulating cooling system usually associated therewith When initially starting motors of this type it is customary to choke, or prime the motor resulting in supply ofexcess of fuelthereto, this fuel, in known manner, causing dilution of the lubrieating. oil, as well as depriving the cylinders of adequate lubrication during the starting period ofthemotor. f I

The prime object of this-invention isto'pro- 'vide a means for rapidly heating the cooling liquid of the motor whereby a temperature approi'iimating that ofnormal operating conditions-said motor will obtain.

" Other objects and advantages will appear as thedescription ofthe invention progresses, and

g, the'novelfeature of the invention will be pointed out in the appended claims. I

1' This invention consists inthe novel construction and arrangement of parts hereinafter described, delineated in the accdmpanyin'gdrawing, and particularly pointed out in that portion is had to the accompanying drawing, whereinl have illustrated embodiments of myinvention, and,wherein like characters of reference, designate corresponding parts'throughout the several views and'in which:- Y I Figure 1 is a front elevational view taken on line 1-1 of Fig. 2-and Fig. 2 is a side elevational view taken on line 2-2 of Fig. 1, and Fig. 3 is a side elevational View of an automatic steam generator, and Fig. 6: isQa sectional view ofa valve taken on line 4-4 of Fig. 5,'and Fig. 5 is a" front elevational View of the same valve taken on line 5-5 of Fig. 4, and Fig. 6"is a sectional view'of a modified form of valve, and Fig. 7 is a side elevational view. of a valve showing a modified VI couplingthereforf and Fig. 8 is aside 'elevational ew of a control valve'associated with the steam generator. a

' Referring to Figs. 1 and 2, showing an inter nal combustion motor and a liquid cooling sys' steam controls the supply of heat thereto 657 whereby a substantially uniform pressure of steam indicated by gage 11 may be maintained within said unit, to the steam outlet 12 is s e-' cured a quick operable valve 13 controlledby I handle 14 and to the'o'utlet of which is secured,

.one end of hose 15.

: .Secured to the ides of unit are brackets 1616 formed to provide spaces 1717into which hose may be coiled when not in use.

Secured to the outlet end of hose15 may also 75 be secured a quickopening valve'18, more fully hereinafter described.- Unit 10 is supplied with suitable handles 19 19 having a caloric insulation'material covering 20 thereover whereby the unit may be transported. Without injury to 73-0,

the hands from excess: heating thereof. I

Referring to Figs. 4- and 5, illustrating one form of valve, '7, forattachmentto radiator '3, body member has'flange ZSarrang ed' to be secured'to the corewall27 of radiator 3,]also g5 tubular extension 28, arranged to, 'enterthrough orifice 29 in said wall to the interior of said radiator core and in'contact withv the cooling liquid therein. I

Supported in canal 30 of body member 26, and 90 arranged-to be restrained to seat 31 by spring 32, allocated by nut 33, having outlet orifice 34;, is valve 35 arranged-when seated to close inlet orifice 36 formed in threaded extension 37 arranged to receive coupling 38 secured to hose 15. 95

Referring to Figure dillustrating a modified form of valve l0,.which is similar to valve 7 however difiers in that extension 41, extends more deeply into the cooling liquid chamber of radiator 3, and the exterior extension42 hasan 1100" internally threaded position 43, a guide bore {14, and a concave seat 45, against which the con cave nose 46 of modified coupling 47 is arranged to impinge. Exterior extension 42 is also formed with a'lug 48 to which cover 49 is hinged by pin 5 50, a suitable springv (not shown) acting to restrain said cover over said extension. I I

Referring toFig. 7, the modified valve is I similar to valve '7 however the threaded exte'n-.-

erators. I

The handles 14 and 63 are preferably also covered with a sleeve formed of caloric insulation terior extension 56 in which are suitably secured bayonet pins 5757. i

Referring to Fig. 8, illustrating a combined valve and coupling 61 for attachment to the discharge end of hose 15, the valve member 61 is preferably of the rapid .openable type having spring returned valve stem 62 arranged to be depressed .by handle 63 hinged to lug 64, by

65L Swivelly secured to the outlet end of valve fil is coupling member 66,-having swivel 6? communicating through tubular member 68 to coupling member 38, a sleeve 69 of caloric insulating material acting to calorically insulatesaid part 1 A similar caloric insulatingsleeve '70 is secured over the discharge end of hose 15, said" to prevent heat injury to op-f sleeves acting material (not shown),

The. operation of the system is as follows:- When a motorist desires to :start his automobile on a cold ,morningthe coupling, as 38, is

attached to valve 7 whereaft'er the valve l i or valve 61-, which ever may be employed, is opened by-depressing handles 14 or 53. Simultaneously steam passes from steam generator 1e, through hose 15 *to valve 7,. the pressure thereof restraining-valve away-from seat 31' thereby permitting; said steam to pass through canal 30 and orifice 34 to the cooling liquid in radiator 3 where itiscondensed, said condensation acting to raise the temperature of said liquid ,in knownim annerh v j n Iti willbenoted that the valve, as '7, is preferably placed opposite the outlet fitting 6, therefore as the steam is injected into the cooling liquid through orifice 34, said liquid is, by injector action, restrained to pass intolconnect'ion 5 and thence tofthe circulating jacket of motor 1, thereafter passing-through connection 4 to the upper-portion of radiator 3 and thence downwardly therethrough' to the valve '7 where it is-again subjected to -a further temperature rise due to the injected steam from valve '7;

whereafter-it is again restrained to pass to motor 1 and complete the, cycle hereintofor described. t

On certain types of liquid circulating cooling system it is preferable to attach a valve as 77a on -the cooling liquidijacket of the motor said valve being similar to any one'of the forms of valve 7 and may be additional to the valve. at-

tached to the radiator 3 or maybe solely em ployed for admitting steamto the system. 1

By employing a comparatively high pressure in'steam generating unit, 10, the temperature of the cooling liquid system-of an, internal combustion motor mayberapidly increased to the 7 replacing the liquid evaporated during the preboiling point, said, heated liquid aotingto heat the motorcylinders and adjacent parts whereby said motor'may be initially started without priming as is now customary in all forms of weather. Furthermoreby thusly preheating the circulating cooling liquid of internalcombustion motors a motor car may be operated smoothly and at maximum capacity as'it is initially placed in motion for service therebyincreasing the economy and utility thereof 7 ."Furthermore by preheating the circulating cooling liquid in the novelmanner hereintofore described the condensedsteam adds cooling liq uid to the system in this manner, automatically vious day's operation ofthe motor,

When a large fleet of motor vehicles, as for example, motor trucks, or buses are to be initially started substantially simultaneously, steam generator. 10 may be made a stationary unit in a remote part of the garage and the steam suitably piped to one or more convenient, locations whereat hose connections as '15, are interposed for more conveniently supplying the steam to the cooling systems of the motor vehicles.

If desired steam generator 10 may be suitably mounted on aiwheeled floor truck for more convenient transfer from one motor vehicle to another. I H
