Budd Manufacturing Company, Phila delphia, Pa., a corporation of Pennsylvania Application September 4, 1943, Serial No. 501,340 2 Claims. (Cl. 257-136) l 2 The invention relates to a heater duct especially for vehicles and more particularly for passenger frames 8 at any desired locations along its longi tudinal extent. The cold and hot water pipes I4, rail cars. I5 are attached to the panel arm 6. ' More speciñcally, the invention relates to im provements in the type of heater duct comprising a housing arranged along the corner of the ñoor and a vertical wall of the room to be heated, which housing contains the heater elements such as a steam or hot Water radiator, though other types ’ ' ' A panel strip I 6 and the ilange along themargin of the horizontal arm I'I of another generally angle-section panel strip are secured by screws I8 to said frames 8. The other arm I9 of the last mentioned panel strip extends upwardly and has its upper margin secured by screws 20 to the panel of heater, for instance electric heaters, may be 10 6’ so that its main body is held at a short dis tance from the panel 6’.

Among the objects of the invention are sim Panel I6 is provided with a row of vertical slots plicity of construction, easy accessibility, eflicient 2l and has its lower margin spaced from the ñoor heating and, above all, comfort for the occupants so that cool air may enter at the bottom and leave, by eliminating overheated zones with which the 15 alftíerzhlaving passed the radiator 9, I0, through the occupants have to or may come in contact, The above and other objects are achieved by a s o s fort of rail car passengers whose feet or lower leg customary constructions, exclusively discharged .
