This invention relatesto automobile heatand control means therefor,
One object of the invention is to prov de an improved heater of simple constructlon and designed to radiate a maximum of heat from a givenlflow of exhaustgas without causing a back compression in the gases tending to choke thenengine.
Another object is to provide a heater adapted to be formed as a single casting and adapted to be arranged either above the floor as when used in touring or other open cars, or below the floor which is preferred when used in closed cars.
Another object is to provide an mproved means for controlling the flow of exhaust gas to the heater.
Other objects are to provide a casing for the heater having means thereon controllable from within the car for maintaining a flow of fresh air past the heater into the car and to provide, in addition, means within the casing for directing the flow of air about the surfaces of the heater in close relation thereto.
The foregoing and other ob ects are obtained by the construction illustrated 1n the accompanying drawings and described below. It is to be understood that the inven- 'tion is not limited to the specific forms thereof shown and described.
Of the accompanying drawings; Figure 1 is a plan of the chassis of a car illustrating the improved heater installed therein according to one mode of carrying for the exhaust gases;
Figure 7 is a section on line 77 of Figure 6- Figure 8 is a section on line 8-8 of Figure 7; and, p 0
Figure 9 is a section throu h a car illustrati 11g another mode of carrying out the 1nvention. 7 i
Referring to the drawings, 10 represents the heater pro er whichis formed as a single, thin wa led, hollow, tubular radiating member of inverted U-s'hape formed with spaced annular pockets 11, 11 in its inner surface and having vertical baflies l2,
For'use in closed cars, the heater 10 is preferably mounted in a casing 14, the vertical arms thereof extending downwardly through apertures 15, 15 in the bottom of the casing and flanges 13 resting on the bottom thereofto support the heater 10 in the casing. Casing 14 is mounted in the car by being inserted downwardly through an aperture 16 cut throu h the fioor thereof and is provided with anges 17, 17 engaging with the top of thefloor and on which is mounted a grid plate 18, the casing 14 and plate 18 being secured to the floor of go 1(gar by suitable means, such as screws Casing 14 is lined with asbestos, as indicated at 20, to conserve the heat therein so that it will all be directed upwardly through grid 18 and has pivoted in the bottom thereof a shutter 21 hinged at 22, 22 and arranged to be opened by a rod 23, loosely connected thereto in any suitable manner, extending upwardly into the car and threaded throu h a fixed lug 24 secured on casing 14 where liy rotation of the rod by the 'occupant will open or close the shutter any desired amount to permit any desired flow of fresh air up through the heater into the car. 7 It is desirable, in order to obtain a maximum effect of the heater 10 on the air flowin u wardly through casing 14, to cause sai air to follow a'comparatively narrow path as closely adjacent the heater as possible.
Accordingly, a bafiie plate 25 is mounted in casing 14 so as entirely to surround heater 10 in a plane parallel to the bottom of the casing and substantially tangent to the inner circumference of the heater, the plate bein formed with a rectangular aperture -define by edges tangent to the outer surfaces of ket rtions 11 whereb air flowing u zi'dly fiast the heater will be directed in The supply of gases to the heater is arranged for by the provision of a Y-shaped valve 26 adapted to be inserted in the exhaust gas line 27 and the branch 28 of which is connected by a pipe 29 to the inlet heater 10, indicated at 30.- Operable on slides 31, 31 in valve 26 is a valve gate 32 reciprocable by a rod 33, so as in one position to close branch 28 leaving exhaust line 27 open, or to close the exhaust line 27 leaving branch 28 open, the ate 32 normally being held in the position s own in Figure 6, to cut oil the supply of gases to the heater and to leave the exhaust line 28 open, by means of a spring 34:. For operating the gate 32 against the action of spring 34, a bell-crank lever 35, pivoted at 35, is connected to rod 33 and has connected thereto a pedal rod 36 operable by the driver throu h the floor of the car and adapted to be etched to hold gate 32 across exhaust line 27 by means of a latch plate 37 on the floor of the car arrangedto engage a ratchet 38 on rod 36.
In the form of the invention shown in Figure 9, casing 14- is dispensed with and a casing 39 adapted to be ositioned above the floor of the car is provi ed, flanges 13 being employed to mount heater 10 on the floor of the car, an asbestos sheet 40 being arranged over the floor of the car under the heater.
In either form of the invention, the outlet indicated at 41 is connected to a pipe 42 extending toward the rear of the car to conduct the exhaust gases from the heater 10.
Modifications of the invention may be re sorted to without departing from the spirit thereof or the sco of the appended claims.
What is claime is:
1. An exhaust gas heater for automobiles, comprising a thin walled, hollow, tubular radiating member having a series of spaced, annular pockets formed therein and perpendicular bafiles extending alternately from opposite sides of the radiating member substantially half way across the same and arranged between said pockets, the inlet end of said heater being free of baffles, and means on said radiating member for supporting the same.
2. A heater for automobiles comprising a heat radiating member through which the exhaust gases are conducted, said member being formed with heat radiating projections, a casing for said member opening substantially the entire length of the bottom and having substantially the entire length of the top opening into the interior of the automobile, means for admitting air into the casing to flow upwardly past said member into the automobile, and a hams in the casing for directing the air in paths upwardly between said projections.
3. An exhaust gas heater for automobiles comprising a tubular conductor formed with spaced projections on its outer surface, said projections having grooves or sockets extending thereinto from the inner surface of the conductor and battles arranged between said grooves on the inside of the conductor adapted to direct hot gases into said grooves with out so obstructing the flow of said gases as to create a back pressure in the conductor.
