MOTbR-VEHICLE HEATING- ATTACHMENT.
Application filed December 4, 1925. Serial No. 73,168.
This invention relates to means for utilizing the waste heat from the motor of an automobile, to warm the body of the vehicle by causing a current of air induced by the forward motion of the vehicle to flow through a drum surrounding a portion of the exhaust pipe of the engine, and enter the body of the vehicle in a heated condition.
The objects of the invention are to pro vide a drum of improved construction, composer; of sections adapted to be quickly and conveniently assembled on the exhaust pipe, and form a drum subdivided into a receivingflue at one side of the exhaust pipe, and a delivering fine at. the opposite side, and adapted to conduct a current of air from an inlet at one side of the forward end of the drum to an outlet at the forward end of the opposite side, and communicating with the vehicle body, so that the current passes in two opposite directions along the exhaust pipe, and is heated during its entire passage.
Another object is to provide a drum construction adaptedto prevent gaseswhich may percolate through the wall of the exhaust pipe from contaminating the air flowing through said flues. v
I attain the above-mentioned and other related objects by the improved construction hereinafter described and claimed.
Of the accompanying drawings forming a part of this spccification,
Figure 1 shows inside elevation a portion of an exhaust pipe and an air-heating attachment embodying the invention associated therewith, and in section a portion of the floor of a motor vehicle body.
, Figure 2 is a section on line 22, of Fig ure 1.
Figure 3 is a longitudinal section of the exhaust pipe, and a drum composed of sections assembled thereon, taken on line of Figure Figures d to 7, inclusive, a re fragmentary perspective views, showing portions of the body sections hereinafter described.
Figures 9 and 9 show in perspective the sections of one. of he heads hereinafter described.
Figure 10 is an end view of the drum, and shows the exhaust pipe in section.
The same reference characters indicate the same arts in all of the figures.
In t e drawings a designates a portion of the exhaust pipe of an internal combustion engine, having the usual mufder b. c designates a portion of the floor of the vehicle body.
My improved heating attachment comprlses a drum composed of body sections and head sections formed to be assembled on the exhaust pipe, and clamping bolts connecting the sections and confining the same in assembled relation on the exhaust pipe, the preferred form of said sections being as hereinafter described. The sections collectively form a longitudinal air-receiving hue 12, extending along one side ,of the drum from the forward to the rear end, and a longitudinal air-delivering flue 13, extending along the opposite side of the drum, from the rear to the forward end. An air inlet 14, preferably a forwardly extending tube, communicates with the receiving flue 12. Said fine is connected at the rear end of the drum with the rear end of the delivering flue 13, preferably by ports or openings 15, formed in the partition portions hereinafter described. The forward end of the delivering flue 13 is provided with an air outlet 16, formed by a-pipe extending to a register 1.7 in the floor 0. The arrangement is such that air admitted at the inlet 16, passes through the receiving flue 12, along one side of the exhaust pipe, and through the delivering flue along the opposite side of the exhaust pipe, the reversely flowing current absorbing heat from the entire portion of the exhaust pipe enclosed by the drum.
The preferred construction and connection of the drum sections are as next described. I
The body of the drum-is formed inpart by a pair of longitudinally extending inner body sections, the rear ends of which are formed as shown by Figures 4 and 5. Each inner body section includes an arched sleeveforming portion 18, and two partition-forming portions 19, projecting oppositely from the sleeveforming portions. The partitionforming portions are abutted together and collectively form a partition between the flues 12 and 13. The sleeve-forming portions collectively surround j and conform closely to the exhaust pipe and said portions and the partition portions prevent gases which may percolate through the wall of the exhaust pi e from contaminating air pass ing throng the flues, it being known that gases sometimes escapes in small quantities through the Wall of the exhaust pipe.
The ports or openings 15, connecting the titio'n portions 19, and secured thereto by clamping bolts 23, as shown by Figure 2.
The outer,body sections are provided at their opposite ends with arcuate flanges 24, to which the heads forming the ends of the drum are secured by clamping bolts 25, as shown by Figure 3.
Each head is composed of two sections 26,
formed as shown, by Figures 8 and 9." The marginal portions of the head sect-ions are secured by the clamping bolts 25, to theend flanges 24. The headsections are provided with lateral flanges'27, which are seated on each other and connected by clamping bolts 28, as shown by 'Figure- 10. Between the flanges 27 are arched flanges 29, which collectively embrace portions of the exhaust pipe at opposite ends of the drum, as shown by Figures 3 and 10, and are secured to the exhaust pipe by set screws 30.
In assembling the sections the inner body sections are applied to the exhaust pipe, the
outer body sections are then applied to the partition portions 19, and secured thereto by the clamping bolts23, and the heads are then applied to the ends' of the outer body sections and-secured thereto by the clamping bolts 25. Finally the arched flanges .29 of the head sections are secured by the set screws 30, to the exhaust pipe.
point nearthe radiator of the engine, and its openforward end may be provided with a damper 32, which may be opened and closed by an suitable means controlled by the driver. hen li'eat is not desired in the vehicle body the damper inay be closed.
Packing layers 33 of compressible material may be interposed between the partitionforming portions 19, to prevent gases from the exhaust pipe from reaching the air ports or openings 15, and entering the fiues, openings coinciding with the o enmgs 15 being formed in the packing ayers. Annular packing layers 34 may be interposed between the arched flanges 29 on the head and the corresponding portions of the exhaust pipe.
I claim:
