3 Claims.

This invention relates to a heating system or means for the water within the jacket of' an internal combustion engine or any equivalent, which is designed to automatically operate to hea-t the water upon lowering of the temperature to a predetermined degree,- in order to avoid freezing of the water in such jacket and make` easy the starting of the motor. l

a A further object is to provide a novel construction which is readily controllable to govern the degree of heat employed.v

It is further aimed to provide a structure which may be built as a unit and constitute an attachment as well as beingcapable of installation in automobiles or the like initially.

The more specific objects ,and advantages will become apparent from a consideration of the description following taken in connection with the accompanying drawings illustrating an operative embodimet.

In said drawings:

Figure 1 is a view in side elevation, showing our improvements applied to an automobile engme;

Flgure 2 is an enla'rged Vertical section taken substantially on the line 2-2 of Figure 1;

Figure 3 is a fragmentary view, on a larger scale, showing the control of the improved device;

Flgure 4 is a view looking toward the interior of the control member;

Flgure 5 is a diagrammatic view showing the parts in position to give one degree of heat;

Figure 6 is a view similar to Figure 5 showing the parts in position to heat to a different temperature; and

Figure 7 is a view partly in plan and partly in horlzontal section of the heater or boiler.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, an internal combustion engine of conventional form is shown at |O in association with its radiator I such engine having a conventional water cooling system. i

Our improvements include a Water container or boiler |2 connected at its top by means of a pipe |3 to the water jacket of the engine |O and connected at its base by means of a pipe |4, with the communicating pipe or conduit |5 between the radiator, adjacent the base thereof, and the water jacket of the engine IO.

Our improvements include a mounting plate |6 preferably of suitable insulation which is attached to the engine IO. Such plate or support IG mounts a plate or supporting ring |l, which or boiler |2.

Said boiler |2 is U-shaped in Vertical section and it has a large recess Vor space |8 rising from its lower end in which is located a suitable core |9, of any suitable insulation, about which, in spiral grooves 20, ,electric heating elements `or resistant means 2| are wound and disposed, adapted to be energised to heat the water within the container or boiler |2, which being heated, will serve to circula'te the water throughout theV cooling system or jacket of the engine IO and radiator to avoid freezing of the water, as when the engine isidle, either on the street, in a garage or elsewhere.

Said heating elements or resistant means at 2| include three resistant elements 22, 23 and 24. Resistant element 22 is connected to a vcontact or conductor plate 25 and through a conductor 2,6 is also connected to a conductor plate 21. Said conductor plate 21 has a pair of conductors 28 and 29, connected thereto and to the coils 2,3 and 24. Said coils or resistants 23 and 24 are bridged by a conductor 30 which is connected to a conductor plate at 3|. Said conductors or contacts 25, 21 and `3| respectively are engaged with clip conductors 32, 33 and 34, bolted or otherwise fastened to the insulating support |6 asat 35. Said contacts or conductors 25, 21 and 3| may be bolted or otherwise fastened as at 36 in a bar or dependent 3'l integral with the core of molded insulation or the like |9. 4

A suitable control member is provided at 38 in the form of a lever and made of suitable insulation, the same being pvoted as by means of a bolt 39 to the support |6. Said support IB carries a receptacle 40, as best shown in Figure 6, which may be engaged by a separable plug connected at any suitable source of electric current, and of any desired Voltage. The source may be the electric battery of theiautomobile having the internal combustion engine IO, or it may be a house lighting supply or otherwise. Obviously the coils must be wound for the desired voltage. conductors 4| and 42 lead from the receptacle 40 and the former is connected to a conductor ring or contact 43 fastened to the support |6. C'onductor 42 includes a thermostat 44 of any desired' type and leads to a disk conductor 45, surrounded by but spaced fromthe ring conductor or contact 43. Said thermostat 44, as shown i'n Figure 1, is preferably connected in the pipe |4 and is adapted to automatically close with the lowering of the temperature of the water in the water Jacket and cooling system, specifically the water passing through the pipe 14, closing the thermostat to make the electric contact for passa-ge of the current through the heating system for heating the Water in the system and preventing freezing therecf. It is obvious that the thermostat is of such a construction and characteristics that it may be adjusted to automatically close any desired predetermined temperature.

Reverting to the control lever 33, it has rigidlyT connected thereto, a ring contact fi and a disk contact in Constant Wiping engagement with the ring contact '3-3 and disk contact 45. Conductor fingers or contacts A33 extend from the ring conductor 'ZS and between the same a nger or contact extends from disk H, passing under the ring 455 at 5d, or otherwise avoiding contact with such ring.

The control lever 38 preferably has an indicator i thereon coacting with the numerals i, 2 and 3, as shown in Figure 3, to indicate a position of the lever and which degree of heat the device is set for.

With the parts in the position of Figure 5, upon closing of the thermostat 44, the circuit Will be closed giving the lowest degree of heat, such circuit including the contacts 46 and 41, contact i and right hand contact 48, contacts 32 and 33, 25, 2? and the single resistant 22 and conductor 25.

When the indicator` 5! is at the position designated 2, the contacts will be in the full line position of Figure 6, thus closing an electric circuit and the contact '21, through finger 49, contact 33, contact 21, conductors 28 and 29, resistant elements 23 and 24, bridge 30, contact 31, contact 3d and right hand finger 48.

Greater heat will thus be produced by the two resistant elements 23 and 24 than by the single resistant element 22..

Still greater heat is possible by including all of the resistant elements 22, 23 and 24 in a closed electric circuit through the parts mentioned, by pulling the control element 38 to the dotted line position shown in Figure 6, all of the i'lngers 48 and 49 being engaged with an adjacent contact 32, 33 and 34 and the latter through the contacts 25, 21 and 3|, and conductors 28, 28 and 30, including all of the resistant elements.

By the anticipated temperature of the weather, one might govern the use of the preferred degree of heat of the three degrees available.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

We claim as our invention:

l. In combination With a heating chamber in the water cooling system of an engine or the like, electric heating means in said Chamber having a core of insulation provided with a projection of insulation disposed exteriorly of the chamber, a support of insulation secured to said projection, and means operable to control the circuit through said electric heating means mounted by said support and projeotion.
