HEATING DEVICE FOR AUTOMOBILES AND THE LIKE.

Specification of Letters Patent.

Patented J an. 18, 1916.

- Application filed January 30, 1915. Serial No. 5,302.

devices incorporated in motor cars and the like. g

The objects of my invention are to provide a device which can be easily and quickly fitted to any ordinary automobile and which is so'arranged when in operative position that it will heat the car effectively and uniformly throughout. This and other objects and advantages 1 secure by the means hereinafter fully described and particularly pointed out in the. claims.

In the accompanying drawings, I have illustrated a preferred embodiment and adaptation of my invention, in which:

Figure 1 represents a side elevation of an internal combustion motor with a fragment of the exhaust pipe leading therefrom, a vertical longitudinal section through a portion of the flooring of the ear in which the motor is mounted, and a side elevation of a preferred embodiment of my invention properly connected to the exhaust pipe and fitted in the flooring of the car; Fig. 2 represents an-enlarged top plan view of the heating element or radiator of my improvement; and Fig. 3 is an enlarged vertical transverse section through the heating element or recllator on line 33, Fig. 2, also showing afragmentary side elevation ofthe connecting pipe, and a transverse vertical section through the exhaust pipe.

In referring to the preferred embodiment or adaptation of my invention shown in the accompanying drawings in detail, similar numerals, symbols, or letters indicate corresponding parts.

I have shown an internal. coml'iustion motor l of conventional type in Fig. 1 of my drawings from which the usual exhaust pipe 2 extends, and have also illustrated sectional portions of the flooring of the body of an automobile in both Figs. 1 and 3.

-The preferred embodiment of my invention, briefly speaking, comprises a heating element or radiator fitted in the flooring of the carbody and a pipe connecting said heating element to the exhaust pipe so that a portion of the hot gases of combustion will flow into and through the heating element or radiator and thereby heat the same.

I prefer to construct the heating element in two hollow rectangular members 4 and 5, one smaller and placed within the other.

The outer and larger member 4 has a remow able top lid or cover 6 which is provided with a plurality of perforations or apertures 7, preferably of square outline arranged in longitudinal rows, and is fastened in place with screws 8, and said member 4 is secured in proper position in the car flooring 3 by screwing orbolting its oppositely-extending top flanges 9 (shown in Fig. to said flooring 3. The interior of the side walls, end walls and bottom wallare preferably lined with asbestos or with other suitable non-l'ieat-conducting material, as shown at 10 in Fig. 3, and the bottom wall is provided with a series of apertures 11 which are preferably of considerably smaller area than the perforations or apertures 7 and constitute air inlets, see Fig. The inner member :"iis of a similar rectangular form to the outer member, except that it is correspondingly smaller in length, 'width, and depth so that it will fit within the outer member 4, and provide an intervening space 12 which completely surrounds the said inner; member 5 and provides for the circulation of air around the same. The inner member 5 is completely closed throughout except at the inlet pipe 13 and outlet pipe ll provided for the passage of the heated gases of combustion into and out of said member.

In the embodii'ncnt shown in Figs. 1 and 3 of my drawings, I extend a vertical seetlon of pipe 13 from the inlet opening and connect it by an elbow 15 to a horizontal section of pipe 16, the outer end of which connects to a globe valve 17 having its hollow depending stem 18 screwed into and through the ventral boss 1 of a block 20 and into an opening extending through the wall of the exhaust pipe, as shown in Fig. 3,

the block being clamped to the exhaust pipe by a lishapcd coupling 21 which bends under the exhaust pipe and has its ends 22 exand drawn tight by nuts 23, fitted upon thetending up through openings in the block projecting ends thereof.

The inner member 5 is. supported in its separated position within the outer member with reference to the bottom wall of said outer member by huts 2424 fitted upon the inlet and outlet pipes 13 and'14 in interposed position between the bottom walls of the respective members, said nuts 2424 also serving to fasten the ends of the pipes 13 and 14 to the heating element or radiator.- I also prefer to secure the inner member 5 within the outer member 4 against upward movement by interposing one or more longitudinal strips 25 of metal between the top lidor cover 6, and the top of the inner member as shown in Fig; 3. These strips 25, are preferably made'of hollow light construction and of triangular cross-sectional form and are arranged with the apex or one of the corners of thetriangle against the under surface of the cover and one of the faces contacting with the top surface of the inner member 5.

It will be noted by referring to Fig.3 that the interior of the inner member 5 is not divided by-any walls, partitions, or.

similar elements placed therein but is entirely unobstructed, providing a large rectangular interior space which is completely filled throughout with the heated gases of combustion and through which said gases can-flow easily and quickly and without any danger of clogging the same, thus securing an'even, uniform, and very efiective means tending entirely around said inner member,.

for heating the radiator. v a

While I have illustrated and described a vpreferred embodiment and adaptation of my invention, it should be understood thatthis is capable of a Wide range of variation and modification without departing from the spirit of the invention or sacrificing any of the advantages thereof, I therefore do not, 'Wish to be limited to the details of construetion'herein set forth, but desire to. avail myself of such variations and modifications. as fairly fall within the scope of the apthe top plate of said outer member being removable and provided with comparatively large outlet openings for the-heated air, and

the bottom of said outer member being also provided with inlet openings for. unheated air considerably smaller in size than the outlet openings in the top plate, and inlet and outlet pipes for the heating agent extending through the outer member and connected to the inner member.

2. A heating device of the class described v comprising a hollow rectangular inner member having openings-near its opposite ends,

for the connection of inlet and outlet pipes;

the remainder of the wallsof said member being imperforate and the interior of said heated air and the bottom of said outer.

member being provided with inlet openings for air and openings for the passage time through of the inlet and outlet pipes for the heating agent extending through the open- -ings in the outer and inner members and into communication with the unobstructed interior of the inner member and means interposed between the lower portionsof the two members and mounted on the inlet and outlet pipes for securing said pipes in 'place and also maintaining said members in their separated position.

3. A heating device of theclass described comprising a hollow rectangular inner memher having openings near its opposite ends Y for the connection of inlet and outlet pipes; the remainder of the walls of said members being imperforate and the interiorof said member beingentirely free 'from obstruc tions and forming in itself a. reservoir for the heating agent, an, outer member of corresponding hollow rectangular. shape and-v suiliciently larger than the ipner member -to provide a circulating spacefor air extending entirely around the inner member, the

top plate of saidputer member being removableand being provided with outlet openings for heated air-and the bottom of said outer member being provided with inlet openings for air and openings for the-passage therethrough of the inlet and outlet pipes for the heating agent extending, through the openin'gsin the-outer and inner members and into communicatienwith .the'

pipes for the heating agent, inlet and outlet unobstructed interior of the inner member, an asbestos lining for the sides, ends and bottom of the outer member having corresponding inlet openings-and openingsfor the passage of the inlet and outlet pipes adapted to register with the similar open- 'ings in the bottom of said outer member,

and means interposed between the lower portlons of the two members and mounted on the inlet and outlet pipes for securing said pipes in place and also maintaining said members in thenseparated posltlon.

In testimony whereof I have hereunto {if fixed my name in the presence of two witnesses.
