HOT WATER HEATER FOR AUTOMOBILES Application filed July 29,
This invention relates generally to heaters for motor vehicles and refers more particularly to those in which hot water from the usual water circulating system for the [6 motor of the 'vehicle is used as the heating medium. I I
One of the essential objects of the present invention is to provide a heater of the type described in which air, preferably'from the interior of the vehicle body, is drawn into contact with coils containing the hot water and after beingheated thereby is forced back into the vehicle 'body.
.Another object is to provide a heater in which the hot water coils are constructed and arranged in such a way that the maximum heating surface is provided for the air and the flow of air around the coils is retarded so that the air will be thoroughly heated before it passes from the heater to the vehicle body.
A further object is to provide a construction in which a single fan advantageously positioned serves as both the means for '25 drawing air from the vehicle body into the heater and for blowing the heated air from the heater into the vehicle body.
A further object is to provide a construction in which the hot air outlet from the heater extends through the dash of the vehicle body and has a flexible connection therewith so that weaving of the vehicle body relative to the motor upon which the heater is mounted will not effect the heater or outlet.
With the above and other objects in view,
the invention consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more 'fully described, and particularly pointed out in the appended claims. In the accompanylng drawings: Figure l is a fragmentary elevation. of a motor vehicle with a heater embodying our invention applied thereto; 1

Figure 8 is a view similar to Figure 1 but showing another modification in perspective;
Figure 9 is a view similar to Figure 1 but "showing a further modification in perspective. 1
In the accompanying drawings we have illustrated a'conventional form of automobile in which 1 is the motor or engine block having suitable cylinders 2 and a water Jacket 3 therefor, 4 is the radiator, 5 is the water pump, and 6 and 7 respectively are the hose connections between the radiator and water jacket, and 8 is the body having a dash 9 provided with a rearwardly extending depression 10.
Referring to our heating apparatus, 11 is a pipe for receiving air from the vehicle body 8, 12 is a blower for receiving air from the pipe 11, 13 is, a heating unit for receiving air from the blower and adapted to discharge heated air into the vehicle body. As shown, the pipell is located above the block 1 at one side of the heater unit 13 and, extends through the dash 9. The rear end of the pipe terminates just inside of the dash and is provided with a peripheral flange 13. The blower 12 includes suitable fan (not shown) and a shell or casing 14 therefor. Preferably this casing is lo-- cated on a bracket 15 secured to the engine block and has one side connected to the forward end of the pipe 11. A motor 16 for actuating the fan is mounted upon the opposite side of the casing 14 and has suitable live and ground wires 17 and 18 respectively. The live wire 17 may be connected to any live wire on the instrument board of. the vehicle-body, and includes a controlling switch such as 19 on the instrument board. The ground wire 18 may be connected to any metal part of the vehicle.
The heater unit 13 comprises a shell or casing 22 and a plurality of hot water coils 23 within said shell. Prr'afelably the' shell 22 is mounted upon the engine block and extends longitudinally thereof between the blower 12 and the depressed portion 10 of the dash. The forward end of the shell is tapered and is connected to the blower casing 14 while the rear end of the shell is open and is received in a metal collar 24 secured to the base 25 of the depression 10 of the dash. Preferably a felt washer 26 is placed between the shell 22 and the collar 24 so as to permit movement of the shell relative to the collar or vice versa upon I movement of the body relative to the motor block, and to prevent vibration and noise,
. especially during such relative'movement.
' In the present instance, the coils 23 are formed of tubing or piping and are arranged this construction the air will be retarded longitudinally of the shell in cone formation with the apices of the cones meeting at the center of the shell, as illustrated in Figures 2 and 3. Preferably the tubing of the coils is provided with fins or disks 30 that serve as heat conductors and retard the flow of air through the shell. Thus with as it flows through and around the. coils and will thereby be heated thoroughly before it passes from the shell to the interior of the vehicle body. Preferably both the intake .and outlet portions 31 and 32 of the tubin' are at the rear end of the shell and may e connected to suitable parts such as the hose connections 6 and 7 respectively of the usual water circulating system.
In Figure 7 we have shown a slight modification in which the blower .0 is secured upon the forward side of the dash 9 and is connected to the forward end of the heater shell 22 by a pipe 41 supported by a bracket 42 upon the motor block. With this construction the motor 43 for the blower fan is secured upon the forward face 'of the blower casing and is ada ted to draw air from the interior of the vehicle body through an opening in the dash to the casing and to force such air through thepipe Hand heater shell 22 back to the interior of the vehicle body. Otherwise, the construction and function of parts are the same as that set forth in Figures 1 to 6 inclusive.
56 is cut in the dash to permit air from the interior of the vehicle body to be drawn thrpugh the dash into the blower. A pipe 57 connected to the blower and tapered end 52' of the heater shell conducts the air fromthe vehicle body to the heater, and the other other modification in which the heater shell .60 is similar to the shell 50 illustrated in Figure 8, but extends forwardly from and at substantially right angles to the dash 9. As shown the rear end portion 61 of the shell is received in a collar 62 in the dash and is cushioned therein by the felt washer 63, while the forward end portion 64 is con-- nected by a clamp 65 to the outlet end of a blower 66 supported upon a bracket 67 secured to the engine block. Thus with this construction the heater and blower are supingan elbow 70. Preferably this elbow and the rear section 71 of the pipe have a slip joint that compensates for movement between the heater and the dash. Otherwise, the construction and function of parts are substantially the same as those illustrated in Figures 1 to 6.
- While it is believed that from the.forego-' ing description the nature and advantages of the invention will be readily apparent, we desire to have it understood that we do not limit ourselves 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 we claim as our invention is:
1. A heater for motor vehicles including a tubular shell having aninlet and an outlet for air, and means for heating air as it is received in saidshell from said inlet including a core opening toward the air inlet and formed of coils of tubing.
2. A heater for automobiles including a tubular shell, and means for conducting a heating medium through the shell, includ-- .ing coils arranged longitudinally of said shell in cone formation with the apices of 3. A heater for motor vehicles including a shell in which air'from a suitable source 1s adapted to be heated," and means for heatthe cones meeting at the center of the shell.
ing the air within the shell, including coils containing a. heating medium and arranged in cone formation.
In testimony whereof we aflix our signatures.
