HEATER AND FOOT-REST FOR VEHICLES.

To all whom it may concern: I 7

Be it known that I, ANDREW J. JOHNSON, a citizen of the United States, residing at Lead city, in the county of Lawrence and State of South Dakota, have invented certain new and useful Improvementsin Heaters and Foot-Rests for p Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use th same. H

The present invention relates to heaters and consists in the combinations and arrangements of elements hereinafter disclosed and particularly set forth in the accompanying claim.

The invention has for its purpose to, provide a heater adapted to be used on motor vehicles, especially on automobiles using the explosive engine as the propelling means, wherein the exhaust gases. from the engine are utilized as the heating medium; and wherein the heater will also serve in the capacity as a rest or support for the feet of.the occupants of the car.

The invention has for its further purpose to provide a heater and foot rest of the character mentioned, which willbe of very simple construction, which may be readily installed on any vehicle, and one which may be manufactured at very small cost.

With-these and other objects in view, the invention consists in the novel details of construction and arrangement of parts more fully hereinafter disclosed and particularly pointed out in the claim.

Referring to the accompanying drawings forming a part of this application, in which like numerals designate like parts in the several views :Figure 1 illustrates the application of the device to an automobile; Fig. 2'

is a perspective view of the device per se,

and showing the parts thereof partly disassembled; Fig. 3 is a longitudinal sectional view thereof, showlng the inner casing in elevation; and Fig. 4 is a transverse sectional View of the inner casing.

Referring to the construction in detail, the heater and foot rest consists of an outer casing or section comprising a body portion 1 made from a single sheet of metal of substantially triangular shape in cross section, and having its respective side edges secured by a flange 2 which over-lies the outer casing wall, as clearly shown in Fig. 2.

Specification of Letters Patent. Application filed. February 15, 1918; Serial No. 748,762.

inner casing consist of Patented Feb. 24, 191,4.

A pair of

end plates

3 and 4 close the ends.

, of the tubular body 1 and provide therewith a heating chamber. Said

end plates

3 and 4 are securedto said body 1 through the dium of flanges 5 and 6 formed on the

respectlve plates

3 and 4, and which over-lie and are crimped against the end wall portions of the body 1. (See Fig. 3).

A second and smaller casing or section is located within the first named, or outer, casing and is likewise constructed of a body 7 formed of a single sheet of metal, and having its respective edges secured by an overlying flange 8, as shown in Fig. 4:. Said inner casing has the ends thereof closed by a pair of plates 9 and 10 secured thereto after the manner of secu ing the plates 3 and a. The end plate 9 of the inner casing 'is secured to the end plate 3 of the outer to supporting (me casing, and in addition said outer plate 3 end of the inner casing carries the inner casing in its entirety when 1 the heater sections are being assembled or disassembled as in the manner shown in Fig. 2. The inner casing, or section, is also of substantially triangular shape in cross section, and is mounted centrally within the outer casing to provide an annular heating chamber 11.

The means for centrally supporting the a pipe 12 that receives the exhaust gases from the motor A of the vehicle B, and a similar pipe 13 which carries off the gases from the heater and delivers'the same to the atmosphere. Both of said

pipes

12 and 13 pass through the

respective end walls

3 and 4 of the outer casing and are secured to the respective end walls 9 and 10 of the inner casing, and communicate with the chamber of said casing. In addition to this means for centrally supporting the inner casing, the end plate 9 of said casing is in any approved manner, as for instance by soldering, secured to the end wall 3 of the outer casing, and by reason of which, the inner casing and said end wall 3 constitute a single unit, which is convenient for assembling or disassembling the several parts of the heater, as in the manner illustrated in Fig. 2. 4

The inner casing 7 which receives the gases direct through the pipe 12, is provided with opposed series of gas escaping apertures 14 formed in the opposite side walls of said casing, and'said apertures are so graduated that the incoming gases when portions or flanges 15, which are disposed within the inner chamber and in the direction opposite to that taken by the entering gases to the end that said gases will be directed into the heating chamber 11. At-

the instant of discharge in the cylinder, the gases enter the member 7 under considerable pressure, and are deflected and compressed within the chamber 11. As the pressure falls, the gases again enter the member 7, and so the device tends to equalize the pressure during each discharge and thus produces the desired mufiling action. During these charges of high and low pressure within the member 7 the gases are free to escape through the exhaust-pipe 13.

The heater-thus constructed is adapted to be installed on a motor driven vehicle without requiring any alterations in the structure of the car, and when located, as illustrated in Fig. 1, said heater provides a convenient rest or support for the feet of the occupants of the car, and in this respect, the heater is in effect a foot Warmer.

The usual muflier G is connected to communicate with the exhaustpipe 12, and said pipe is provided with a valve D adapted to be operated through the medium of a lever,

E, to the end that the exhaust 'or treadle,

be directed into the mufiler, or

gases may into the heater, as desired.

Itis obvious that those skilled in the artmay vary the details of construction as well as the arrangement of parts without departing from the spirit of my invention, and

1 therefore, I do not wish to be limited to the above disclosures, except as may be required by the claim.

What I claim is In a heater of the character described, the combination of a sheet metal body portion of substantially triangular design in cross section, and plates crimped on the edges of said body portion and providing therewith a closed chamber; a second and smaller casing located within the first casin and comprising a sheet metal body portion of triangular cross section, and plates secured to the ends of said inner body portion and providing therewith a closed chamber; one end plate of said inner casing secured to one of the end plates of the outer casing and adapted to be carried by said last named end plate when the heater sections are being assembled or disassembled; a pipe passing through the secured end lates of said casings and adapted to de iver heated gases into the inner casing; and a second pipe passing through the other end plates of said casings to support one end of the inner cas ing, and conduct the gases from said heater; said inner and outer casings providing a heating chamber; and the body portion of said inner casing having inwardly struck portions providing opemngs of increasing dimensions toward said outlet pipe, and

adapted to deflect the passing gases from the
