ATTORNEYS Patented Nov. 1, 1938 PATENT OFFICE AIR HEATER Edwin Hui-ford and Richard Johnson,

Detroit, Mich.

Application July '1,

1 Claim.

The invention relates to a heater and more especially to an air heater accessory for motor vehicles. I

The primary object of the invention is the provision of a heater of this character, wherein the gases from the exhaust of a motorvehicle will be utilized for heating air and such gases in their travel will have, a spinning motion within the heater so that quick and thorough heating of air can take place prior to distribution within a vehicle body for heating purposes.

Another object of the invention is the provision of a heater of this character, wherein the same is susceptible of mounting within the exl5 haust pipe leading from the exhaust side of a motor installed within a motor driven vehicle so that the exhaust can be utilized for the heating of air to be delivered interiorly of the body of the vehicle, the heater being of novel construc- 20 tion.

A further object of the invention is the provision of a heater of this character, which is simple in construction, thoroughly reliable and efilcient in its operation, enabling the use of the exhaust 25 gases from an internal combustion engine for the heating of air to be distributed, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction,

30 combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses-the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a vertical longitudinal sectional view through a heater constructed in accordance with the invention.

Figure 2 is a sectional view on the line 2-2 "40 Of Figure 1.

ends l3 of the body l0, these end portions being joined with the ends I! by flange formations I4. 55 The formations snugly embrace a heating drum 5 1936, Serial No. 89,396

which is carried centrally through the body and which outside of the body has the contracted portions IS with pipe extensions I! which are suitably joined with an exhaust and a mufller as built within a motor driven vehicle. The exhaust gases are admitted from the exhaust of the'vehicle motor into the drum l5 through one end thereof and discharged from its other end in the direction of the muflier (not shown).

The lining ll of the body III is set outwardly from the drum l5 to effect an air space l8 concentrically about said drum. Cold air is admitted to the space It through an air inlet l9 and discharged from said space after the heating thereof through an air outlet 20, these communicating with the space at opposite ends with respect to the body I0.

Arranged at the longitudinal axis interiorly of the drum I 5 is a tubular shell 2| having an outwardly tapered pointed tip or end 22 confronting the exhaust and formed with this tip are spiral vanes or wings 23 so that the exhaust gases entering the drum IE will effect a spinning motion between the shell 2| and the drum l5 to be carried about the latter in a spiral manner and in this way uniformly heating the air circulating through the space l8 when admitted through the inlet I9 and delivered through the outlet 20. The other end of the shell 2| remote from the tip or end 22 has connection with webs 24 which function to hold the shell centered within the drum l5 while the vanes or wings 23 also center the said shell. The exhaust when spinning about the shell 2| will flow to the muiiier for exhaust to the atmosphere.

Within the shell 2| is a filling of a silencing compound 25 for the purpose of silencing the exhaust when passing through the heater, the compound being preferably'asbestos and refractor materials.

The construction of the heater as hereinbefore set forth renders the vehicle motor noiseless and eliminates exhaust noises and additionally assures the heating of the air flowing through the space It as admitted through the inlet i9 and delivered through the outlet 20.

The body In and the lining H as constructed afiords a dead air space 26 therebetween so that the air circulating through the space I8 is protected against weather elements during the working of the heater.

What is claimed is:

A heater of the kind described comprising a cylindrical body having an internal lining spaced therefrom and forming a dead air space therebetween, a' drum fitted centrally within thebody and having the lining concentrically spaced therefrom to form an air circulating course, a tubular shell having an outwardly tapered pointed tip and disposed within said drum and spaced from the inner surface of the drum, an air inlet pipe having tangential connection with said air course at one end thereof, whereby air entering the course through the inlet pipe will pass through 10 the course in one spiral direction, means for connecting said shell to an exhaust of an internal combustion engine at the end adjacent the air inlet pipe, vanes secured to said tip for imparting to the exhaust a spiral movement opposite to that of the air in the air course, and outlet means for the air and the exhaust at the other end of the shell and air course.
