As shown, the frames are constructed of side members ill of‘ double channel section of the form indicated. in Figure 5, these being two channel members of the form shown in my pend ing application Serial No. 360,868, ?led October frominfr'a-red producing lamps. Ovens for this purpose have been in use for a considerable period and usually consist of frames of welded or bolted angle or‘ channel members 12, 1940,.and'being'f welded together‘back to'back. carrying suitable lights arranged 'so as to con By using this form: of channel member form to the shape of the article and be‘ as near 10 throughout‘ and thefas'tening means shown, parts the latter as possible. may be ?rmly secured at any point along a chan Such ovens do not readily lend themselves to nel and'no slippage can occur.
