To all whom it may 00mm.-

Be it known that I, EUGENE F. SMITH, a citizen of the United States, residing at Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Automobile Heaters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same. i i

This invention relates to automobiles and other engine driven vehicles, but more particularly to certain new and useful improvements in heaters for engine driven vehicles.

The primary object of the invention is to provide a heater-for engine driven vehicles adapted to receive its heat from the exhaust of the engine, and at the same time to muffle said exhaust so as to overcome much of the noise necessarily incident to the running of an engine. 7

Another object of the invention is to improve upon devices of this class by the porvision of a comparatively simple, strong, durable and inexpensive construction, and one which will be efficient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerous other objects in view the invention consists of certain novel features of construction and the combination and arrangement of parts which will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of the application, and in which similar characters are used to designate like parts throughout the several views Figure 1 is'a diagrammatic plan view of an automobile equipped with this invention;

Fig. 2 is a side elevation of the heater detached;

Fig. 3 is a vertical sectional view through theheater on the line 3-3 of Fig. l; and,

Fig. f is a vertical sectional view taken on ,theplane indicated by the line l4e of Fig. 3.

Referring more particularly to the drawings, the letter A designates an ordinary internal combustion engine, and B the exhaust pipe of the same. Arranged beneath the floor of the automobile, preferably in advance of the portion of the same above which the seats are disposed, are hollow casings or heating chambers 1, each of which is formed of two asbestos-lined relatively long and narrow portions 2 and 3. The portions Specification of Letters Patent. P tent d mayg'jl, 19131,

Application filed May 9, 1917. Serial No. 167,462.

2 and 3 of each casing are arranged at right above the upper side of the portion 2. The

numeral 4 designates register plates which are fitted upon the open tops ofthe portions 3 of the casings and secured thereto in any suitable manner. Each of these register plates forms a part of the casing whose upper end it covers. As shown, the plate 4 is provided with a plurality of perforations, but it is to be understood that openings of any form or configuration may be substituted for them. vThe lower side or bottom of the portion 3 is inclined from its outer to its inner end to assist in causing the hot air from the portion 2 of the casing to be directed toward the top of the portion 3 and out through the perforated registerplate.

Projecting centrally and outwardly from one end of the portion 2 of each casing is a short nipple 5. Theother end of theportion 2 is provided with a comparatively large opening 7 through which a tubular or cylindrical element 8 is inserted into the interior of the casing. After this is done a plate 9 is secured in any suitable manner to the last mentioned end of the portion 2. This plate 9 carries the centrally arranged outwardly extending nipple 10 which is similar to the nipple carried at the other end of the portion 2. The nipple 10 of one heater and the nipple 5 of the other heater are attached, by means of unions 6, to pipes C which are connected to the exhaust pipe B. The remaintogether by two nipples and a short pipe section I).

As shown, the tubular element 8 is of a length such that when it isdisposed longitu dinally in the portion 2 of the casing, and the plate 9 is secured to the proper end of the same, the pipe section will be maintained firmly in place. To prevent any possible leakage between the casing and the ends of the tubular element 8, the ends of the latter are broadened or radially flanged, and suitable packing l1 isdisposed between said ends and the adjacent sides of theplate 9 and the other end of the portion 2 of the casing.

Extending transversely through the element 8 and inclining forwardly from their 111g unions 6 of the two casings'are connected upper to their each casing, near their vlded with openings 13 through whlch a1r 7 lower ends is a plurality of tubes 12. As shown, these tubes 12 are arranged in two rows extending longitudinally with respect to the tubular element 8. The

lower end of each tube 2 is cut off rightangularly, while the upper ends thereof are cut ofi all in the same plane. This construc tion provides a means for causing circulation of the air both around the element 8 and therethrough by way of the tubes.

The opposite sides of the portion 2 of lower edges, are profrom the outside may of the casing.

It is to be understood thatthe automobile pass into the interior 'OIfOtheI vehicle maybe provided with as many of theheaters as it has seats, and these may be arranged in any convenient manner and location in the machine, the pipe section or pipe sections D being dimensioned and shaped according to the require ments of each case.

The relatively long and narrow registers are in open communication with the interior of the automobile and extend transversely of the automobile floor and through the greater part of the width ofthe latter, so that the heated air is dispensed in a relatively narrow and long space across the floor, and several persons on the same seat of the automobile may be equally benefitted by one of the heaters. This advantage is obtained in spite of the location of the portions 2 and their tubular elements at one side of the automobile. By thus locating the portions 2, however, they do not interfere with the driving shaft, nor with other centrally located parts, and are arranged in close proximity to the laterally disposed 'exhaust pipe B, so that the exhaust is not cooled appreciably in passing from the engine to theheaters.

Because of the portions 2 being relatively long and narrow and positioned as explained in the foregoing they are susceptible of the maximum capacity and air-heating surface while providing for the utmost convenience in attaching the casings to one another and to the automobile.

After the engine has been started and it is desired to heat the machine, a'two-way valve 14: arranged at the junction of one ofthe'pipes C and exhaust pipe B is operated so as to cause all or a portion of the exhaust from the pipe B to passthrough the heaters. This hot exhaust heats the air contained in the casing, and this heated and lightened air passes upwardly through the same and out through the register plate 4 Copies of thispatent may-be obtained for five cents each,

into the interior of the ear. Cold air enters the casings or hot-air chambers by way of their inlet openings 13, and a considerable portion of this cold air is drawn through the tubes 12, in consequence of the air being heated therein and rising therefrom. It is obvious, therefore, that these tubes 12 render the heaters extremely eflieient.

From the foregoing description, taken in connection with the accompanying drawing, the construction, use and operation of the device will be readily understood without a more extended explanation. As various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit of this invention, it is to be understood that I do not wish to be limited to the precise construction herein shown and described.

I claim:

1. In a heater for engine-driven vehicles, a hollow casing formed of two relatively long and narrow intersection portions arranged at right angles with respect to each other, one of said portions of the casing including an apertured register plate through which it is in open con'nnunication with the interior of the vehicle, said portion and its registering plate extending transversely of the vehicle and through the greater portion of the width of the latter, the other portion of said casing having air inlet openings therein, and a tubular element extending through said otherportion of said casing and adapted to be connected to the exhaust outlet of the vehicle-engine.

2. In a heater for engine-drix en vehicles, a unitary structure comprising a hollow casing formed of two relatively long and narrow intersection portions arranged at right angles with respect to each other, one of said portions of the casing projecting laterally of the other of said portions and extending from one sideto and beyond the other side of the other of said portions, this laterally projecting portion including an apertured register plate in open communication with the interior of the vehicle, said other portion of the casing having air inlet openings, and a pipe extending through said other portion of the casing and, adapted to be connected with the exhaust pipe of the vehicle-engine.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
