RADIATOR Filed 00f. '23. 1930 Patented May 9, I933 v UNITED STATES EDMUND ROSER, F BOCHUM, GERMANY RADIATOR Application filed October 23, 1930, Serial No.

My invention relatesvto improvements in radiators and more particularly in radiators provided with a fan for circulating the air and rapidly delivering the same into the room to be heated. The object of the improvements is to provide a radiator of this type in which the heat is rapidly and thoroughly transmitted from the radiator elements and the heating effect of the radiator is improved. Another object of the improvements is to provide a radiator in which excessive heating of certain parts of the radiator is avoided. With these objects in view my invention consists in disposing the fan at the rear side of the radiator comprising a plurality of heating elements disposed one beside the other or one above the other, the fan being disposed so that the air rises at the rear side of the radiator, where- 0 upon it is deflected at its top for flowing downwardly along the front side of the heating elements. Thusthe air is delivered from the radiator in a direction towards the floor of the room and at a part of the radiator where transmission of heat also takes place by radiation.

In one embodiment of the invention I make use' of electrical heating members mounted on rods of insulating material, the

said rods being individually disposed within semi-cylindrical screens disposed one above the other or one besidethe other and overlapping one another with their longitudinal margins and providing slots at the 3 said margins for the passage of the air therethrough. Thus a part of the current of air flows from the rear side of the radiator to the front thereof, and it is directed against the electrical heating elements. Thus when switching in the current the room is 'rapidly heated because the heat cannot be stored at any part of the radiator, and it is directly transmitted by the current of air and by radiation into the room. By the current of 5 air also the cold air located near the floor is moved and replaced by warm air.

For the purpose of explaining the invention twoexamples embodying the same have been shown in the accompanying drawing in which the same reference characters have 490,695, and in Germany October 25, 1929.

been used in all the views to indicate corresponding parts. In said drawing,

Fig. 3 is a sectional elevation showing a modification,

Fig. I is a sectional elevation taken on the line 4:-4 of Fig. 3, and t Iiig. 5 is a sectional view showing a de- In the example shown in Figs. 1 and 2 the radiator is heated by means of gas, and it comprises upper and lower tubular members 10 and 70 connected by vertical pipes b, the gas being supplied through a pipe Z and the burned gas escaping through a pipe Z The radiator is supported on a base m, and it is confined within a casing comprising a rear wall 0 and a front wall 6, the said walls be ng connected at their top by a semi-cylindrical wall having a container z for water fitted therein. The casing c, e is divided by the radiator and partition walls n located between the pipes b and extending to the side walls of the casing into a rear chamber a and a front chamber a and the rear chamber a is closed at its bottom by a plate M. The rear wall a is formed with a circular hole having a flanged ring a fitted therein, and to the rear wall a frame 0 is secured in which a motor (Z for driving a fan al is mounted on a bracket (Z The front wall 6 is formed at its bottom part with a large opening p.

In the operation of the apparatus air is taken in by the fan d and delivered upwardly through the rear passage a and alongside the rear wall of the radiator. At the top of the casing the current of air is directed downwardly and through the front passage (1 from which it is delivered into the room through the opening )2. Thus air is transmitted into the room by the current 9 of air and in addition by radiation.

In the modification shown in Figs. 3-5 the casing enclosing the radiator consists of a rear wall 0 and a front wall 6 and the rear wall 0 is provided with a motor d and a fan ti the said motor and fan and associated parts being similar in construction to the corresponding parts described with reference to Figs. 1 and 2. The front wall e is formed with an opening]? whlch extends from a part near the bottom to a part near the top of the casin The radiator comprises electrical heating members 6 made in the form of wires helically wound on rods Of refractory material. Each heating element is disposed within a semieylindrical radiating shield f located at the rear there of, and all the said shields are disposed one above the other so as to provide a partition within the casing 0. At their adjacent margins the shields are spaced from each other to provide downwardly directed passages g. In the operation of the apparatus the air taken in by the fan (1 flows upwardly through the rear passage of the casing, and thereafter downwardly to the front side thereof from whence it is delivered through the openin 12 A portion of the air flowing upwar ly through the rear passage is deflected through the passages g and towards the heating elements, thus effectively cooling the same and transmitting the heat outwardly and into the room. The concave portion of the shields f is directed outwardly, so that the heat radiated from the heating elements is thrown into the room.
