This invention relates to new and useful improvements in apparatus for heating the interiors of automotive vehicles such, for instance, as sedans and buses, and an object of 5 the invention is to provide such an apparatus y com rising a heating member having a con-v nection with the water-circulating system of the vehicle engine whereby ,hot Water will be circulated through the member, means'be l ing provided in connection with the heating member for forcing the air within the vehicle body therethrough to heat it and to keep such heated air in continuous circulation withinlthe vehicle body. l
vide an air-heating member adapted to be mounted within a vehicle body and having'a connection with the water-circulating system of the engine and, further. having means yfor ldiverting substantially all or a portion of the water through the heating member to heat the interior of the vehicle body. y A further object is to provide such an apparatus including an air-heating'member comprising a plurality of horizontally disposed, spaced tubes, each ada ted to be surrounded by water, said member aving means for connecting it to the water-circulating system of an internal combustion engine, whereby a circulation "of hot water may be established therethrough, a valve being interppsed in the .connection `between the intake and discharge conduits of the heating member whereby the flow of water through the heating membermay be controlled. l A- further object is to provide 4a combination hot water and air-'heating apparatus for automotive vehicles, comprising a heat-radiating member having an electrically operated 40' fan mounted adjacent thereto for circulating the air within the vehicle body through the heating member, and means such as a rheostat for controlling thesspeed of the motor-drivenfan whereby the circulation f heatedair within the vehicle body may be controlled independently of the vehicle engine.
A further object is to provide a hot water heating member, comprising a plurality of l l .horizontally disposed tubes arranged in j spaced parallelrelation, whereby Water-circulating passages will be provided between the'tubes and each 'tube will be completely surrounded `by water, thus .providing a heat-- A further object of the. inventionv is to pro-l Application 'for member which 4will (pickly heat the air circulated through the t by the action of the fan or blowerA means mounted adjacent to the heating member. y
A further object .is to provide a heating r apparatus for automotive vehicles of simple and inexpensive construction, comprising few parts, and, which may readily and quickly be installed in a vehicle and-connected to the` .usual water-circulating system thereof, in a comparatively short period of time without the necessity of having to vmake numerous alterationsto the 'usual connections or fittings of the vehicle engine.`
Other objects ofthe invention will appear l from the following` description and accom.-
panying drawings ,andthe novel features `will e pointed out in the' annexed claims.
In the drawings there has been disclosed a structure designed to carryI out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown, as various changesv may bemade l within the scope of the claims which follow;
In the accompanying drawings forming ,heating member; j

In the .selected embodiment' of the inven.
tion here shown, forpurposes of disclosure, thereis' illustrated a portion of an automotive vehicle comrising the usual engine 11, water-cooling ra iator 12 and the connection l13 connecting the/water-jacket of the engine with the radiator 12,
' The novel heating apparatus featured in this invention is best shown in Figures 1 and y 2, and comprises an air-heating member the usual dash 14 of the vehicle beneath the ada ted to be suitably mountedor secured wit in the vehicle body, as, for instance, to
`A fitting 32 is interposed in the connectiony 13 between the engine water-jacket and the radiator 12. I This fitting is provided with tubular extensions`33 and 34. preferably ary ranged at one side of the fitting as shown in Figures 5 and 6. Conduits 3G and 35, preferably flexible, connect the pipes 19and` 22 respectively with the extensions 33 and 34,- as shown in Figure 1. A valve 36, preferably of the butterfly type. is mounted in the fitting 32 between the tubular extensions 33 and 34. Thisvalve'36 is operable from the exterior of the ttingby means of a shaft or rod 37 shown in Figure 6. By means of this valve, substantially all or a portion of the wat-er flowing fromthe engine water-jacket to the radiator 12, may be `diverted 'through the heating member for heating the interior of the vehicle body. s
Means are provided. for establishing a forced circulation of heated air within the vehicle body.v Such means consists of a fan 38 mounted back of the heating member bctiveen the tubes 16 andthe plate 29, and is operable by a small motor 39 mounted upon a s ider or frame 41 'carried'by the lower tiebo t's 26, as shown in Figures 1 and 2. The motor 39, is electrically connected by conductors 42 and 43 to a suitable source of electrical energy such as the Stora battery 44 of the vehicle. L( See Figure 7. A small rheostat 45, of ordinary construction is connected in series with the conductor 43 and provides ,means for controlling the speed of the motordriven fan 38. This rheostat is preferablyI mounted u on the instrument board of the vehicle so that it may be conveniently mani pulated by the driver to control the circulation of heated air within the vehicle body. .This rheostat has been found very useful in actual practice'as it provides a positive means for controlling the heating of the interior of the vehicle, regardless of the temperature of the water circulating through the heating member. This will readily be seen when it is understood that the heating of the interior of vthe vehicle body is governed largely by the circulation of the heated air therein, as forl instance, whenthe fan is operating at high speed, the air within the vehicle body will be rapidly circulated through theheater, thus heating it to a comparative high temperature, while, on the other hand, when the fan is inoperative, the circulation of the air within the vehicle body will beV practically at zero; By the employmenttof the fan- 38 to forcibly circulate the air through the heating member. the latter-may be lmade relatively small and compact in size without jeopardizingits heatingefliciency. This is an importantfactor, as the heater will require verylittle spacein the vehicle as compared to the amount of space l usually required. by' automobile heaters of ordinary construction. Also, as a result of its compactness, practically no heat will be dissipated from the heater when the fan 38 is inoperative. The rheostat.. therefore, has been found an important adJunct in connection with the above described heating apparatus.
By heating the 'interior lof thevehicle body,
as above described. the usual danger ofmonoxlde gas entenngthe vehicle, as when using Avarious forms of heaters now in common use,
is eliminated.v The foul or gaseous air usually found beneath the engine hood is also excluded from theinterior of the vehicle body, it being understood that the air .heated and circulated within the yvehicle body is that conned therein only, or that which enters misi through cracks or crevices in the vehicle or through doors land windows, when thellatter are opened and closed. y
An 1m rtant feature'of the invention resides in t e generalconstruction of the heating member and the air-circulating means which, it will be noted-by reference 'to Figllo ure 2, are assembled 'as a unit. By thus assembling as a unit the heating member vand the blower and fan, the installation of the.' lheater in the vehicle is greatly simplified.
The construction of the heating member is such that `Aeach tube 1,6V is completely surrounded by water so that the air, blown or circulated throu h the tubes by thefan 38, will be quickly cated to a relatively high tem rature in passing therethrough. It has n found from actual practice, that by lengthening the tubes 16, the velocity or circulation of the airtherethrough for a given water temperature may be decreased without decreasing the effective heating of the interior of the `vehicle, as a result of the increased length of lthe tubes subjecting the 'eliminating any danger of the motor 39'being overloade when operating to circulate the air Within the vehicle body to maintain a i comfortable temperature therein on an cxtremely cold day. l
The valve 36within the fitting 32, provides means whereby the flow of water through the heating-member. may be cont-rolled orregulated at will. It has been' found, however, that by varying .the speed of the motor fan 38, the temperature within the vehicle body may be regulated to the desired v degree without having to manipulatev the water-controlvalve 36.
It is apparent that by cutting oii the flow of the engine water circulating system, from the hot-water air-heater, say, by' means of the valve 36, and operating the fan 38 by the motor 39 air will be circulated throughout the vehicle body at a rate depending on the speed of rotation of the' fan under control of the rheostat of the electric motor so as to cool or lower the temperature of the air within the vehicle body without obnoxious fumes entering from the chamber which contains the engine'. p
