CARL J. PATTERSON AND OLIVER J. KILBURN, OF JACKSON, MICHIGAN..

AUTOMOBILE-HEATER.

To a]? whom it may concern:

Be it known that we, CARL J. PaTrERsoN and OLIVER J. luLBURN, citizens of the .llnited States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful-Improvements in Automobile-Heaters, of which the following is a specification.

This invention relates to exhaust heaters for automobiles, and has for its object a simple construction that can be clamped over the exhaust manifold and run into the bodyv time effectively accomplishes the heating.

In the'drawings, v Figure 1 is a side elevation of a Ford power unit showing the heater clamped in I place.

Fig. 2 is a vertical longitudinal section of the heater.

Fig. 3 is a cross section, of the same taken on the line 3-3 of Fig. 2. v i

a designates the usual Ford cylinder block;

J) the crankcase cover,'and c the transmission. d indicates the carbureter; e the intake manifold, and f theexhaust manifold. a: designates the so-called stove that is clamped to the manifold by the band 2 fitting ont the stud i. This stove has a flue 1 leading to the carbureter air intake to furnish warm air to the carbureter. The intake manifold and exhaust manifold are bolted to the cylinder block by yoke-like .clamps g.

which are threaded onto the studs 2'. These manifold clamps are quite common construc tion in all types of automobile engines where the two manifolds are on the same side of the engine. Our heater comprises simply a hood of sheet metalwhich at its forward end is bent into sinverted U-shape with one of the legs of the U considerably longer than the other (see Fig. 3). At the rear end the same sheet of metal is bent into tubular form to form the pipe j. The'apron m or long leg of the U of the forward portion is recessed at k and Z for the purpose of straddling the threaded studs upon which the manifold clamps engage, as will appear from Fig. 1.

These openings straddle the two center studs. The clamps; as appears from Fig. 1, are adapted to engage the metal of this depend- Specification of Letters Patent. Patented NOV. 8, 1921. Application filed ianuary 10, 1921. Serial No. 436,086. 7

ing apron m on either side of the apertures k and 7, and when the nuts are screwed down air thrown from the fan and direct it into v the heater. Around the U metal sheet at the top thereof above the apron m is secured an asbestos sheet h that acts as a heat insulator. This fastening is accomplished by riv-t eting or spot-welding the metal sheet 0 over this asbestos sheet. The pipe jis adapted to project into the interior of the body at the junction of the dash and floor board, as indicated in Fig. 1, at one side andbelow the coil box 7).

One of thefeatures of this heater is that a simple butterfly valve (1 is mounted in the extreme end of the pipe 7' where it acts both as a control for the air passing through the tube and also by reason of being at the extreme end can be used as a deflector. For instance, the heated air can be directed toward the driver of the car or away, just as desired, by simply turning this deflecting valve slightly.

Another important feature of this construction is that the U-like portion of the heater also fits over the ordinary stove a: and hence the air drawn into the stove has travfold. It is, therefore, much hotter and is possible to cut down the carbureter needle valve adjustment so as to make a material saving in gas.

\Vhat we claim is:

An exhaust heater for automobiles, comprising an open front and open bottom hood formed of a single piece of metal bent into inverted U section with the long leg of the U arranged to run down the outside of the manifold forming an apron with afree bottom edge into which are cut recesses for straddling the yoke clamp studs and permitting the yoke clamps of the manifold to enersed the entire length of the exhaust manigage the bottom of the apron to hold the heater to the engine, the top of the hood including the other leg of the. U being supported in free suspension above and on the inside of the manifold by the yoke clamps engaging the said apron, a reinforcing sheet of metal secured over the hood at the top and part way down both sides; and a sheet of heat insulating material retained between such reinforcing vsheet and the hood, the 10 In testimon whereof We aflix our si natures.
