Specification of Letters Patent.

Patented July 2l, 1914..

Application led April 6, 1914. Serial No. 829,976. l

To all whom t may concern Be it known that we, J. C. KANE and FRANCIS E. HUGG, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Heaters for Automobiles, of which the Vfollowing is a specification. i

This invention relates to improvements in gas heaters, and has particular reference to a gas heater so constructed that the same is of the proper shape and size to be installed within or upon an automobile, in an out of the way position.

An important object of the invention is to provide a gas heater of the above mentioned character, which is of simple construction, inexpensive to manufacture, compact, and adapted to be arranged below the seat of an automobile, while not necessarily restricted to such location.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a front elevation of a gas heater embodying the invention, Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. l, Fig. 3 is a front elevation of the saine, with the frontI plate removed, and Fig. fl is a horizontal sectional view taken on line 4:--4 of Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 desig nates the body portion of the heating shell or casing, the same being of sheet metal, and including a Hat baclr 6, sides 7, a horizontal. floor or bottom 8, and a forwardly extending inclined top 9, as shown. The forward side of the body portion 5 is formed open, and is normally closed by a front plate 10, formed of sheet metal, adapted to engage with and be secured to an outwardly extending flange 11 formed upon the body portion 5, as shown. It is thus seen that the construction of the heating shell or casing is compact, the same being adapted to be vertically arranged when in use. The upper portion of the inner surface of the back 6 and top 9 is lined with a sheet of asbestos Il', shown. Arranged within the main heating shell or casing is an inner partition l2, formed of sheet metal and aording a vertical chamber 13. The vertical edges of this partition 12 are provided with flanges 14:, secured to the front plate 10, by means of bolts or rivets 15, as shown. The lower end of the partition 12 is spaced a substantial distance from the floor or bottom 8 and the upper end of the same is spaced a substantial distance from the inclined top 9, as shown.

Mounted within the partition 'l2 or chainber 13 are a plurality, two being considered an advantageous number, of vertical tubes 16, arranged in spaced relation and rigidly connected with the side of the partition 12 by means of bolts or rivets 17, as shown. The upper end of the partition 12 is bent forwardly to forman inclined top 18, passing above the upper end of the tubes 16 (the upper and lower ends of these tubes being open), and projecting outwardly beyond the front plate l0, in the form of a downwardly inclined deflector 19, as shown.` The front plate 10 is provided with

horizontal openings

20 and 21, arranged above and below the deflector plate 19, as more clearly shown in Fig. 2.

Extending into the lower portion or the bottom of the main heating shell or casing `is a preferably horizontally arranged gas supply pipe 22, adapted to have connection with the acetylene gas tank carried by an automobile and which is ordinarily employed to supply gas to the headlights of the machine. This pipe is preferably provided with a cut-off valve 23, arranged within the main heating shell or casing, with its stern 24 extending outwardly through an opening in the front plate 10. the same being preferably formed square in cross-section for engagement with a wrench 0r suitable tool, to turn the same.

Connected with this gas supply pipe 22 by means of T-couplings 25 are gas burners 26, which I have found may be of the same type as ordinarily used in the headlights of an automobile, the same being adapted to burn acetylene gas. The upper forked ends of these acetylene gas burners 26 extend into the lower ends of the tubes 16 for a substantial distance. Adjacent the upper end of these burners, the tubes and front plate 10 are provided withv openings 27, to afford access to the burners whereby the same may be lighted, said openings being normally closed by swinging doors 28, pivoted at 29. Below these doors 28 the front plate 10 is apertured or provided with air supply openings 30 through which air passes, to travel through the air passage 31, as indicated by the arrows in Fig. 2.

As clearly shown in Fig. 2, the numeral 32 designates a portion of the seat of an automobile, while the numeral 33 designates a portion of the floor of the same. The heater is adapted to be arranged below the seat 32, and is connected at its upper end with the seat by means ofv screws 34 or the like, passing through apertured flanges 11 formed upon the body portion 6 and the apertured edge of the front plate 10. At 'its lower end the main heating shell 5 is secured to the oor 33 by means of screws 36 or the like passing through apertured flanges 11 and the apertured lower end of the front plate 10, as shown.

In the operation of the heater, assuming that the same is arranged below the seat of an automobile, where it is particularly adapted to be disposed while not necessarily restricted to such location, the burners 26 being lighted, the products of combustion or heated gases pass upwardly through the tubes 16. These products of combustion are deflected forwardly by the top 18, and pass through opening 21, and are again deflected downwardly by the deector plate 19. By the time the products of combustion have passed from in proximity to the deflector plate 19 they are suliiciently cooled whereby they will not over heat the feet or legs of the occupant of the automobile. The heat within the tubes 16 heats the air within the passage 31, causing the samel to circulate upwardly therein, this air entering through apertures 30, passing upwardly through passage 31, deflected forwardly between tops 9 and 18, and discharging forwardly and upwardly through openinY 20. This air does not attain a heat su ciently high to cause inconvenience to the occupant of the `car and is deflected upwardly to heat the upper portion of the car.

It is to be understood that the form of the invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I-Iaving described the invention, what is claimed is 1. In a gas heater for automobiles or the like, a main upstanding heating shell having one side thereof formed open, a removable plate covering the open side of the heating shell and provided near its lower end with an air inlet opening and near its upper end with a gas discharge opening, a partition secured to the inner side of the removable plate and having the upper end thereof bent to forman inclined top portion arranged adjacent the gas discharge opening, and a burner arranged within the lower end of the main heating shell and adapted to discharge products'of combustion into the chamber formed by the partition and plate.
