JULIUS E. HETTINGER, OF CHICAGO, ILLINOIS. I

HEATER FOR AUTOMOBILES.

To all 'whom it mayV concern.'

Be it known that I, J ULiUs E. Herrmann, a citizen of the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Heaters for Automobiles, of which the following is a specification.

This invention relates to heaters for heating vehicles or cars such as trucks or automobiles which are driven' by internal combustion engines, and which have water jackets for cooling the en 'nes and radiators for -cooling the water.

ne of the objects of the invention is to-provide means for transferring the waste heat of the engine, b

liuids, to the body of the machine, so as to warm the persons in the machine, or to protect -any perishable goods which-may be in the trucks from injury by becoming too cold. Other objects of the invention are to provide means for increasing the radiating surface used in coolin the water, and to provide suitable means Ier using the apparatus either for heating purposes or for additional radiating purposes, as may be desired. Other objects of the invention will be apparent from a. consideration' ofthe accompanying drawings and the following descriptionthereof.

Of the accompanying drawings Figure 1- is an elevation'ofan automobile, with portions broken away, which has mounted there* in certain means Jfor ca ing out my invention; Fig. 2 is a plan view of the engine and` radiator of the machine, together with Athe nclosing casing;

the heater which I use; Fig. Sis an enlar ed plan view of the heater or radiator;

Fig. 5 is an end view' of the heater casing; Fig. 6 is a perspective view of one s1de of Fig. 7 is a perspective view of another side of the casing; and Fig. 8 is a perspective view of a device -As is well understood, it is 4common with automobiles and trucks `tohaveA a' water jacketed engine and. to have aradiatonin the machine which'is directly connectedl with the water jacket, and to which the water -iiows, and Afrom which the heat thereof is A.radiated away, so` that the water in the jacket may be kept suflicientl cool.- However, inthe apparatus which use carryspecineation of Letters Patent.

means of the water, or other suitabletions othe ig. 4 is a section-along the line 4-4 of-Fig. 3;

the heater formed by the ipes 12'by meansL of -a pipe 13, to the-top of t e ordinary radiator 14 of the machine, and then by means of `a vpipe 15 I connect the bottom of the radiator 14 with the bottom of the'water j aclretI ofthe engine. v

When the pipes are arranged in the man` i ner specified it will be seen that there will be a continuous 'flow of water from the water jacket around through the heater pipes 12, back to the top of the radiator -14`,- and finally vto the bottom ofthe water jacket, due to the cooling of the water in the radiator 14 and in' the pi e 11 and the downward iiow thereof. At t e same time the water in the heater pipes 12 will be, continually losing heat by radiation from, the pipes,l and this heat will be used in heating the car.

In orderto prevent dangerof vbreaking the pipes from vibrations and otherwise, and

to provide simple. means for'connecting or disconnecting the ipes, `I provide flexible couplin s 16 and 1 to connect various porpipes. In this manner any strains due to limproper placing of the pipes, or to strains on the automobile itself, will be avoided, and also danger of fracture by Vibrations will be eliminated, and the pipes can be conveniently detached when desired. For instance if it is desiredto disconnect theheater itself from the system it is necessary only to disconnect the couplings 16 and 17 from the ypipes and to connect the two ends of the pipes which are joied to the' front radiator and the engine b means of the iiexi'ble tube 18 (Fig. 8) an the circulation of the water will continue as before, while the heater itself may be entirely removed.

In order to prevent waste of heat, I inclose a portion of the

pipes

11 and 13 in a conduit 20 having a` lining 21 of non-conducting substance, and I also inclose the heater itself in a casin 22, the walls of which have, in the sides t ereof, non-conducting sheets 23, the bottom 25 of the casing being composed iio of a sheet of suitable metal 26 oneach side f of a sheet of non-conducting substance 24.,

such as asbestos. When the heater is to be used for heating purposes the upper surface of the casing 22 is covered by a sheet 27,

through the openings of which the heated air from the pipes is allowed to pass.

However, the

sheets

27 and 25 are interchangeable, so that, while in cool weather the sheet 27 may be used on the upper surface of the casing 22, so as to allow the heated air to pass into the machine, and the.

lsheet may be used for the lower surface so as to prevent heat from passing downwardly, yet in warm weather the two sheets may be reversed, so that no material amount of heat can pass upwardly into the machine, vbut the'heat may be radiated down freelyl through. the sheet 27 and also by the sheet sides they are fixed in place in the caslng 22 by ymeans of catches 30, so that b simply springing these catches o from t e sheets the sheets may be removed and very easily interchanged. The heater may be composedof an suitable form 'of pipes or chambers. Iy have shown-in this mstance round pipes for the purpose, but it is to be understood that oval or flat pipes may be used if it is desired. The pipesare supported in the casing by means of cross pieces 31 which' rest upon beams 32 extending across the machine from one side of the chassis to the other,- and resting upon the chassis beams 33, the beams 32 projecting through the ends of the casing 22, as indicated. Cross pieces'35 hold the provided for running the water out 'ofthe various pipes firmly in place. By these means the heater pipes may be conveniently removed from the easing or the entire casing may be removed rom the machine, whenever desired. And when the casing is 'removed the opening may be closed by means of the cross bars 32 and the

plates

25 and 27 resting thereon. Apetcock 34 is piges whenever desired. p

y this means a very effective' and convenient heating apparatus is provided. The hottest water passes immediately from the water jacket ack into the machine,'the

hottest' portion of the pipe 11 passing im mediatelyl beneath .the Hoor of the front seat,

through, said pipes, a casing inclosing said pipes, said casing having a detachable heat non-conducting bottom and a detachable metal open work top, the shape and size of said bottom being substantially the same as the shape and size of said top, whereby said bottom and top are interchangeable.-
