andf Statey of Ohio, have invented certain` newv andv usefulr Improvements in Automatic Heating Systems,.of which the following is a specification.

This invention relates to heating devices, and more particularly to means for heating thewater for the cooling system of'an auto mobile internal combustion engine;

One. o4 the main objects ofthe invention is to. provide simple and eicient means which. may be readily applied to the coolingy system of an. automobile engine. of the in! ternal combustion type So as to` prevent ireezing' of the same during cold weather. A further object is to provide simple and elicient means for automatically throwing the heating device into and out' of'operation in accordancewith variations in temperature of the water in the coolingA system.. Another object s-tor providemeans whereby the heatingI device .may be readily,v connected to a storage battery or to the magneto orl other source of electrical. energy; as` conditions may" require.- Further objects will appear from the detailed description.

In the drawings-:

`Figure 1 isV a.` diagrammatic view' of a. heating devicey constructed in accordance with my invention, as applied.

Fig. 2 isa fragmentary section through the heater.

A. suitably constructed casing-'1 is mounted adjacent to;- one? side ofY the engineA of thev automobile, and rearl ofV the radiator B,

this casing. is divided by horizontal? plates or partitions 2" and 3 into upper'A and lower water chambers which are connected-p by a plurality of. spaced vertically' disposed andy narrow waterl tubes. 4 Heating; coils 51 are mounted` between these tubesand the lower ends of these` coils. are connected by a wire 6 tol one pole off an induction coil' 'I'. The upper ends of the heatingcoils are connected by a lead 8 to a contact; 9- of av thermostatv 10 of suitable type mounted in a cap 11 connected: by' a nipple 12V to the lower water chamberv of' casiiig4 1f. The thermostat includes a Slidable rod 13 provided at its up@ per end a: bridge piece 14 forv connecting? contact' 9` to contact 15- of" the thermostat when the rod is; lowered.

understood,` when the. temperatureY ot the water the lower'compartment. of the cas ing, falls belowv a predetermined. point, rod 18 is lowered so as to. connectY theI contacts 9 and 15V through the medium. ofl bridge p1ece14.

(jontact'V 15 is connected byv a wire 16,. in which is interposed a switch 17, to thee other pole of the secondary coil for induction coil 7. One pole of the primary coil of indue-- tion coil 7. is connected by a wire 18 to a contact jaw 19,the other pole of the-primary coil being connected by a wire 20l to a con'- tact jaw 21. The jaws 19 and. 21 cooperate with a two bladed doublethrow switch 22,k onev pole 23v ofy which is connected by a wire 2a,v in which is interposed a switch 24a, to wire 6, the other pol'e25v ot'this switchbeing connected by a wire 26 to wire 1.6. Switch 22* also cooperates with.l two contact jaws 27 connected by wires 28'to a plug 29y by. means of which'. these wires may be connected to a suitable socket,` which is connected to an electric light circuit: orany other suitable source of electrical energy; The. blades of switch 221titinto. contact jaws 301 and 31 p0- sitioned a short distancev from contacts 21 and' 19, when the switch is in the position illustrated., Contact jaw 31 is connected by a wire 32;'to one pole ot a.` storage battery 33 which may be mounted in. any suitable positionv upon the automobile, and the other pole of' this: battery isconnected byV av wire 34:.to1 contact jaw 30.

The uppery water compartmentv ofv the radiator` Bf is connectedy by a hose section Cy to, the water jacket ot* the engine in the known manner,` and the. lower compartment ot the radiator isconnected byV hose section D tothe lower water compartment of casing 1 the upper water compartment of which is connected byv hose4 section 35.y toV theA water jacket of the engine.

As will'. be understood, the waterl of the engine coolingsystem circulates through the tubes 4 of the. heating device. and throng-h the radiator and?` the Water jacket. in the known manner. When this water falls belowi a predetermined temperature, the thermostat` 10 connects contacts 9and 15. With the switches 1'?, 22, and* 24* in the relative positions: illustrated, current from battery 33 tlowsthrough the primary coil ot induction coil 7.' The induced 'current in thesecondaryl winding of the induction coll will How through heating coils 5 so as to heat the water flowing through tubes 4 sulciently to eieetually prevent it from The storage battery is preferably used when the automobile is standing still on the road. During travel of the automobile, and aiter the engine has warmed up sutlciently, the switch 22 is thrown into open position, thus saving the battery current. During the time when the automobile is stored away, the heating current may be obtained more cheaply from a local light circuit. To this end, switch 22 is thrown into its other position, switch 17 being opened and switch 24* closed. With the switches in this position, current will flow from plug 29 through wires 28 to wires 24 and 26, and thence through the heating coil,.when the thermostat rod 13 is lowered, the storage battery 33 and induction coil 7 being cut out. Whenever required by the voltage o the local light circuit, suitable means may be inserted in line 28 to reduce the voltage in the heating coils 5, as indicated by resistance 28. Preferably, though not necessarily, in practice suitable connections are provided between switch 22 and switches 17 and 24:, by means of which switch 17 will be closed and switch 24 opened when switch 22 is thrown into the position illustrated, switch 17 being opened and switch 24:* closed when switch 22 is thrown into its other operative position. YAs will be understood, and as indicated herein, slight changes may be made in details of construction and arrangement of various parts of the invention without departing from the eld and scope of the same, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which a preferr-ed form only of my invention is disclosed.

What I claim is In combination with an internal combustion engine including a water jacket, a radiator having its upper water compartment connected to said jacket, a casing having an upper water compartment and a lower water compartment communicating with the water jacket and the lower water compartment of the radiator respectively, tubes connecting the upper and lower compartments of said casing, heating coils mounted between said tubes, a source of supply of electrical energy connected to said coils, and means interposed tothe circuit of said source of supply of electrical energy for closing said circuit when the temperature ot the water owing through said casing falls below aA predetermined degree.

In testimony whereof I aiix my signature.;
