This invention relates to heaters, and more particularly to heaters designed for utilizing the heat from the exhaust gases passing through the exhaust pipe of a motor vehicle for heating the interior of motor vehicles.
The primary object of the invention is to provide a heater of this type which will retain the heat for a considerable length of time after the motor with which the device is associated has been stopped.
A further object of the invention is to provide a heater which is cast or otherwise formed in a unit, thereby insuring against leakage of the exhaust gases to endanger the lives of the passengers or persons riding in the vehicle by poisoning from the carbon monoxide gas.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the 'details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing.
Figure 1 is a longitudinal sectional view through a heater constructed in accordance with the invention.
Figure 2 is a sectional view taken on line 2 2 of Figure 1.
Figure 3 is a side elevational View of a modified form of the invention.
Figure 4. is a sectional View taken on line 4-4 of Figure 3.
Figure 5 is a plan view of the modified form of the heater.
Referring to the drawing in detail the device in its preferred form includes a substantially tubular body portion 5 within which is formed a substantially tubular member 6 through which the exhaust gases from the exhaust pipe of the motor with which the device is used, pass.
rllhe reference character 7 designates a pipe that leads to the member 6, the pipe 7 being connected with the usual exhaust pipe so that the exhaust gases may pass there- Serial No. 247,930.
through. At the opposite end of the body portion is a pipe 8 through which the exhaust gases pass on leaving the portion 6 of the heater.
As clearly shown by Figure 1, the tubular member 6 is considerably smaller than the body portion 5 'defining a space between the tubular member and body portion to receive a heat retaining material 9, which in the present showing embodies soap stone, al-
though it is to be understood that other heat retaining mediums may be used without de-V parting from the spirit of the invention.
Interior threads are formed at the Vends of the tubular member 6 to accommodate the threaded closures 10 that are designed to close the ends of the member 6, under normal conditions, but when it is desired to remove carbon which will collect within the member 6, these closures 10 may be removed and a suitable cleaning instrument inserted in the ends of the member 6 andthe member G thoroughly cleaned' so that the heating qualities will not be impaired by foreign matter collecting in themember 6.
A similar closure 11 closes an opening formed in one end of the body portion 5, and through which opening the soap stone or heat retaining material is passed to the in-Y terior of the body portion.
Brackets 12 are formed at the ends of the device and are supplied with openings to receive securing nails or screws, whereby the device'may be secured to the floor boards or flooring in the rear of the body of the car at a proper place to warm the feet of the occupants of the vehicle.
In the form of the invention as shown by Figure 3 of the drawing the body portion which is indicated by the reference character 13 is substantially rectangular in cross'section and is supplied with a flange 14 so that the body portion may be positioned in an opening formed in the flooring of a motor vehicle to heat the vehicle, and at the same time provide a device which will be out of the way of persons moving in the body of the vehicle.
A pipe indicated at 15 extends into the body portion 13 at one end thereof, and extends to a point adjacent to the opposite end of the body portion 13 where it bends and extends in parallel relation with the sides of the body portion and extends downwardly and passes rom the body portion to deliver the exhaust gases from the body portion after they have accomplished their purpose.
A plug 16is fitted in a threaded opening formed at one end of the body portion so that soap stone or similar heat retaining material ma bey positioned in the body portion to absor the heat of the exhaust passing through n the pipe to transfer the heat to the interior of the vehicle with which the device is used.
From the foregoing it will be obvious that due to this construction the heat from the exhaust gases passing through the exhaust pipe, of a motor vehicle, and Ywhich is ordinarily wasted, is utilized to heat the'interior of the motor vehicle withV which the device is used,
and because of the heat retaining material, the heater will be maintained hot for a considerable-length of time. after the exhaust gases cease to Vpass through the device, thereby eliminating the necessity of running the motor to heat the vehicle, when the vehicle is parked with persons seated therein.
I claim: Y
A heating device of the class described, including a lhollow body portion, a pipe formed integral with the body portion and extend-l ing throughout the length thereof, the ends of the pipe being open to the atmosphere, said pipe being spaced from the inner surface' of the body portion defining a compartment, heat retaining materialarranged within the compartment, a plug for normally closing one end of the compartment, a feed pipe communicating with the first mentioned pipe, andan exhaust pipe communicatingv with the first mentioned pipe at the op osite end ofthey first mentioned pipe,'brac ets on the body portion yfor securing vthe body portion -to a 1 su ortino'surface.y
In testimony that I claim the foregoing as my own, I have hereto aixed my signature.
