J. J. lSUNDAY HEATER FOR AUTOMOBILES Filed Feb` 9, 192e March 25, 1930.

Patented Mar. 25, A1930 UNITED STATES PATENT OFFICE 'Juas J. SUNDAY,Y or DETROIT, IIICIIIGAN, AssIGNon To JAMES w. xELcH.' or l l DETROIT, MICHIGAN f HEATER FOB' AUTOMOBILES Application filed February 9, 1926. Serial No. 87,024.

f This invention relates generally to heaters .for automobiles and consists of certain novel features of construction, .combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing: v a Figure 1 is a fragmentary side elevation ofl an automobile with a heater embodying my invention applied thereto. Figure 2 is an enlarged fragmentary elevation of the heater with certain parts in section.

A Figure 3 is adetail elevation of one of the partitions. Y l

' Figure 4 isa top plan view of the air inlet duct. i

Figure 5 is a front elevation of the air inr, let duct. v 2o Referring now-to the drawing, 1 is aheater embodying my invention having concentrically Aarranged inner and outer shells 2 and 3 respectively. As shown, the inner shell 2 is'divided by spaced transversely extending apertured disks or partitions 4 into a series of chambers 5 in which the exhaust gases from the engine are adapted to expand, while the outer shell 3 is closed at its ends and is providedadjacent to -said ends, preferably at diametrically opposite sides 'of the inner shell with inlet and outletl openings 6 and ''leiY spectively or air. To provide` an efficient construction, the partitions 4 are provlded with the lateral peripheral iianges 8 that fit inner-wall of theshell 2, while the closed ends of the outer shell 3 are provided with the laterally extendingflanges 9 that lit snugly around and are-rigidly secured to the outer f wall of the shell 2. Preferably the ianges 8 of the end walls 4 and the flanges 9 of the shell' 3 terminate flush with the ends of thej shell 2, hence these parts may be securedtogether along their 4outer edges by a slngle welding operation. h

In order that the heater may be applied to exhaust conduits of various sizes, the end walls 4 of the inner shell are preferably'pro-` vided with openings 10 of suiicient area to receive the largest exhaust conduits now in snugly Aagainst and are rigidly secured, to the standard conduit section 11 and are dis-- charged from the rear end of the shell into a standard conduit section 12. Thus, with this arrangement, suitable adapters having openings of various sizes may be employed for holdin the conduit sections rigidly in assemble position.l As shown, the adapter 13 preferably comprises the cooperating plates 14 and 15 and the resilient gaskets 16. To facilitate assembly, these plates have` openings therein for receiving suitable bolts 17, while the gaskets 16 are clam ed between the plates 14 and 15 by means o bolts. Inasmuch as these boltsV extend outwardly through the end walls 4 it is apparent that the adapter plates 13 may-be easily and quickly applied to or removed from the heater. In this 'connection it will be noted that the bolts 17 are prevented from falling or being pushed inside theheater when the adaptf' er plates are applied by means of the rearwardly converging walls of a perforated coneI into a suitable conduit 2O which leads from the outlet-opening 7 to a suitable register 20 in the floor of the vehicle body. As shown,

the duct/19 is provided at its forward endwith an outwardly flaring port-ion y21 and is these securing` provided intermediate its ends with the up-- wardly extending longitudinally curved top wall 22. Located within this duct, preferably below the curved top wall 22, is a baille 23 that preferably extends upwardly from the bottom wall of the duct to a point in substantial alignment with the upper wall 24 at the rear end Yof the duct. Thus with this construction water, dust and foreign matter of any kind entering the duct through its ared forward end will be effectively prevented by the battle 23 from passing into the heater shell 3. In this connection it will be noted that. the bottom wall 25 inclines downwardly from the baflie 23 to the forward end of the duct, hence iiuids stopped by the bai-lle 23 will be discharged from the duct by draining down the inclined bottom 25. If desired, a small port or opening (not shown) may be provided in the bottom Wall 25 adjacent to the baille to permit the escape of such foreign matter.

To facilitate the attachment of the heater to an autotmobile, the air conduit 20 is preferably swiveled in the outlet opening 7 in the outer shell, hence this conduit may be readily adjusted to a convenient position for attachment to the register in the floor of the automobile body.

Thus, from the foregoing description, it

will be apparent that the apertures in the cone 18 and partitions 4 will permit the eX- haust gases to flow freely through the shell 2, hence these parts will serve effectively to deaden the sound of the engine exhaust without causing objectionable back pressure on the engine. It will also be apparent that the tubular shell 2 will receive the heat thrown off by the gases flowing through the chambers 5 and therefore will provide a large heating surface for the air within the outer shell 3. Thus, this construction serves efficiently as a combined heater and muflier.

While itis believed that from the foregoing JAMES J. SUNDAY.

description, the nature and advantage of my invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. A heater for automobiles including a chamber for exhaust gases having an opening therein, an adapter for exhaust conduits having an opening in alignment with the opening in said chamber. means for detachably securing said adapter to said chamber including headed elements projecting outwardly from said chamber, and a delector for said gases upon the inside of said chamber forming a receptacle surrounding the headed elements for preventing said securing means from falling or being pushed inside the chamber when the adapter is being adjusted.

2. A heater for automobiles including an inner shell constituting a muffler casing provided With end walls having longitudinally extending peripheralflanges secured to the inner wall of said shell and terminating flush therewith, an outer shell surrounding said inner shell and spaced therefrom to form an Yair chamber and provided with lateral inturned lianges contacting with the oilter wall
