10 Claims. (Cl. 257--137) This invention relates to heating apparatus radiator header to discharge the water, which and more particularly to distribution of heat has flown through the heater, back to the cold from heaters in motor cars. part of the circulating system. The heater per It is usual in the present form of motor car se is formed of an outer casing 30, generally in heaters to have some source of heated air adthe shape of a cylinder with two flattened sides. 5 jacent the dash board of a car and a fan for The rear portion of this outer casing has aseries propelling that heated air out at right angles to of holes 32 surrounding the periphery which act the dash into the car. These heaters are as air inlets. Adjacent the rear end of the casing mounted at some distance above the floor of the is secured an angular bracket member 34 to car and as the heat tends to rise it leaves a cold which are secured bolts 36, which pass through 1 area near the floor which makes it uncomfortable the dash board I8, and a backing plate 38 to sefor the feet ofthe' driver and passengers as they cure the heater on the dash by means of nuts get practically no heat. 40.

Secured within the casing,

of our invention. The inlet tube 22 of the heater the from o 3 ea 1 n e 9 par is connected, by suitable piping 24, t t of the compartment, ahead of the radiating elemotor head to cause the hot water therefrom to ment 46 and Ju behmd t Ornamental e circulate to the heater. The outlet pipe not the 5 is rigidly pp d a ed baflle member 62 55 heater is also connected by pipe 2! to the lower extending between the side plates 12 and which 55 pivotally supports at its upper extremity an extension baflle 64, which may be set in any desired position to regulate the forward flow of air. The central portion of the extension baiile 64 adjacent its pivotal point has an integral forwardly extending lip 68 which projects toward the forward portion of the casing and may be used to regulate the position thereof. Openings 80 are provided in the lower portions of the side plates 12 to allow air to flow to the louvers 5|.
The operation of the heater is as follows: Air is drawn in through the openings 32 in the rear of the casing by the fan member 44 through the fan housing 48 and through the heat radiating surfaces of the radiating element 46 into the forward chamber 10. The air coming through the lower portion of the radiator 46 strikes first the baflle 62 and is discharged either through the louvers 50 in the bottom of the compartment 10 or through the louvers 5| in the lower side portions thereof. The air going through the top portion of the radiator 46 goes through the top of the compartment Hi and out through the forward doors 58, the amount passing through the doors of course being conditional upon the amount the doors are opened. Considering that the doors 58 are wide open and the bailie. in the position shown in the full lines in Fig. 3, approximately 50 per cent -of the air will be directed forwardly and 50 per cent downwardly. If the movable extension 64 is moved down to the dotted line position, shown at 64', per cent of the'air will be discharged forwardly and the remainder down, while if the extension 64 is moved to the dotted line position 64" approximately 75 per cent of the'air will be discharged downwardly and only 25 per cent forwardly. Of course it will be evident if the forward doors are closed tightly all of the air will be discharged downwardly. With this type of structure air is discharged directly on the floor boards in the forward portion of the front compartment and therefore eliminates the cold spot occasioned by most heaters at this locality. Due to the side louvers 5| air is directed toward the driver's feet as well as directly down upon the feet of the passenger occupying the right-hand seat. In this way the air can be controlled so that the passengers are comfortable in cold weather by having any required amount directed toward their feet and also-a given amount directed toward the upper portion of the body so that they will be comfortable.
Although we have here illustrated the device as being used with hot water heaters, it is evident that the same might be used with a hot air or steam heater to the same advantage therefore the invention should not be limited to the present showing. It might also be noted that without either the rigid or adjustable baille, with openings in the lower portion of the casing and with the closure of the doors, a certain amount of heat would be directed downwardly. We have therefore devised heat distributing means within the heater casing for distributing the air to different parts of the automobile body to prevent cold spots, and thus give more comfortable i We claim:
