Abstract

628,721. Unit air heaters. DELANEY, C. T., and GALLAY, Ltd. Oct. 9, 1947, No. 27160. Drawings to Specification. [Class 137] [Also in Group XI] The subject-matter of this Specification is substantially the same as that described in Specification 628,720, but the claims differ. In particular the unit air heater described in this Specification does not have a hollow outer wall providing a passage for cooling air, but has a rotary switch disposed beneath the lid of the device, a carrying handle being secured to the switch spindle which is vertical, and an inverted conical plate is arranged below the switch to deflect air to the outlet louvres and away from the switch. Four switch positions are possible.
