Application filed January 28, 1922. serial No. 532,508.

To all whom itmury concern:

Be it known that I, Ronnnr W. WIEDER- WAX, a citizen of the United States, residing This invention relates to heating devicesit for the cooling systems of motor vehicles.

Inthe present invention, I provide a casing adapted to fit the front and rear of a radiator having shutters to control the flow of air through the radiator. A burner is 15 arranged within the casing at the front and.

a passage 18 provided for air to support combustion. The products of combustion pass ofi through a vertical passage commumeating with a horizontal passage at the top 2c of the casing which is arranged adjacent a ortion of the air passage to preheat the air. hence, the products of combustion pass through the radiator.

object of the present invention 1s the as provision of a heater comprising a casing which may be closed when the burner is lighted for heating purposes and opened when the vehicle is running.

A further object of the invention is the provision of. means for supplying preheated air to the burner.

A further object is the provision of means for preheating the air by the products of combustion and then passing the products of combustion through the radiator.

In the accompanying drawings, 1 have shown one embodiment of the invention. In this showing:

Figure 7 is a side elevation of the casing,

Figure 8 is a central vertical sectional view on line 8-8 of Figure 1,

Figure 9 is a detail view of the shutter actuating mechanism,

Figures 10 is a horizontal sectional-view on line 10-10 of Figure 8, and,

Figure 11 is a detail sectional view on line '11-11 of Figure 4.

. Referring to the drawings, the reference numeral 1 designates generally a motor vehicle provided with a radiator 2. The radiator communicates -with the lower water chamber 3, and an upper chamber 4, each of I which is connected to the cooling jacket of e the engme (not shown), in the usual manner.

The heater forming the subject matter of the present invention comprises a front casing 5 which is arranged in front of the radiator and supported in any suitable manner. As shown, the casing is provided with side walls 6, the ends of which are flanged, as at 7. A strip 8 is secured to the side wall ad j acent the flange, and this strip is provided with a pair of flanges 9 and 10, arranged substantially'parallel to and spaced from the flange 7.

The front wall adjacent the radiator is formed of alternate stationary and movable plates producing a shutter efiect. As shown, the stationary plates 11 are secured between the flanges 9 and by suitable fastening elements 12. The movable plates 13 are arranged between each pair of stationary plates, and the ends of these movable plates are offset, as at 14, and received between the flanges 7 and 9. These plates are arranged slightly ofi-set from the vertical plane of the stationary plates, as shown in igure 2. The movable plates are connected to a rod 15,- having a rack 16 formed adja cent its upper end. This rack meshes with a pinion 17, carried by a' horizontal rod 18, extending through the radiator and provided with an operating handle 19 in frontof the casing.

The rear of the radiator is closed by a. casing or plate which is likewise provided with alternate stationary and movable sections. This rear plate consists of stationary sections 20 and movable sections 21. The movable sections 21 are provided with od-set ends 22, which are received in spaces formed by

plates

23 and 24 of vertical strips 25, secured to the rear of the radiator. These movable sections are similarly connected by Nil vided with slots 29 to permit the plates to move upwardly.

Beneath the bottom of the radiator, the

front is provided with a solid wall 30 and a bottom 31. The wall 32 extends upwardly from the bottom of the front casing to the lower level of the radiator. At the top of the radiator, the casing is provided with an inclined wall 33 having a plurality of openings 34. Beneath the inclined wall, there is provided an air passage 35, formed by horizontal walls 36 and 37, and vertical walls 38 at the front and rear. This passage communicates with openings 34, by means of an inclined passage 39. Adjacent the side of the passage 35, there is provided an air duct 40, extending to a point beneath the upper end of the Wall 32. At the opposite side of the casing, a vertical passage 41 is provided. This passage forms a flue for the escape of products of com bustion, and communicates with a space 42, at the top of the casing above the air passage 35. The walls of the air passage may be provided with openin 42.-

Adjacent the bottom, there is provided a horizontal wall 43, extending from one side of' the casing to the vertical wall formin the inner side of passage 41. The end of the air duct passes through this wall. The

horizontal wall 43 and the bottom form a burner easing which is adapted to receive a burner casing 44. The burner casing comprises a fuel tank 45, and a burner tank 46, separated from each other by a perforated wall 47. The fuel tank is provided with a filling opening, closed by a cap 48. The burner tank is provided with a filling 49 of suitable fibrous material to retard the flow of liquid fuel. A burner 50 is arranged on the top of this tank, the burner comprising a base plate having openings 51 for the passage of air spaced from the top of the burner tank by legs 52. A wick 53 is mounted in a wick chamber 54, and is provided with the usual control member 55. The bottom of the wick extends through the top of the burner tank. as shown in Figure 4 of the drawings. When the burner is in position, the top of the burner co-operates with the horizontal wall 43 to form a transverse air passage 56 to deliver air from the air duct 38 to the burner. The side wall adjacent the burner is provided with a door 57 hinged thereto, as at 58, which may be opened to insert and remove the burner and fuel tank.

This door is provided with a slot 59 for the eaneao passage of the burner control member 55, and is further provided with a transparent window 60 to permit inspection of the flame. The door may also be provided with a suitable catch 61.

Beneath the radiator, the

walls

30 and 32 of the front casing are provided with alined openings inwhich a sleeve 62 is arranged The starting crank 63 of the engine is adapted to be passed through this sleeve.

The operation of the device is as follows:

When the engine is running, or in warm Weather, the shaft 18 is revolved through handle 19 or 28 to move the

plates

13 and 21 upwardly behind the plates 11 and 20 and thus permit passage of air through the radiator for thepurpose of cooling the fluid in the cooling system of the motor. When the engine is standing. in cold weather and there is danger of freezing, the burner 50 is lighted and the products of combustion pass up through the vertical chamber or flue 41 to the space 42. From the space 42, the gases pass around the tubes of'the radiator, heating the water or other fluid and preventing it from freezing. The flow of the products of combustion creates a draught in the horizontal passage 56, causing air to enter openings 34 and pass through passages 35 and 39 to the air duct 40. The incoming air in the passage 35 is heated by the products of combustion in the space 42. It will be noted that this space is open in the front of the horizontal passage 35, which permits the products of combustion to flow on all sides {2; of the air passage 35 before passing through the radiator.

The openings 42' are provided to permit escape of some of the incoming air through the radiator when the amount of air supplied is more than is necessary to support combustion. The air passing through openings 42 joins the products of combustion and passes through the radiator. The products of combustion in the flue 41 heat the space between the front wall of the front casing and the front of the radiator, and this heat is conveyed by radiation through the radiator, thus heating the entire radiator. The space 42'being in free communication with the radiator, except at one side where the flue 41 is provided, any back drafts escape downwardly into the space removed and replaced by opening the door It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
