4943. Mower, C. H., and Sturtevant Engineering Co. March 4. Air, heating; air, supplying, methods of. - In apparatus for heating and circulating air in a workshop or the like, a centrifugal fan draws air from the room optionally mixed with fresh air downwards from the upper part, over a heating-coil, and disc h a r g e s it horizontally over a wide area near the floor. In the construction shown, air from the room, drawn into the heater through openings h, may be mixed with fresh air entering by a pipe i, the amount of fresh air being determined by the position of an adjustable sleeve j. Baffles k regulate the path of the air over heating-coils g to a fan c, which discharges it horizontally through openings b at the bottom.
