To hold the front and back panels of the door in correct relationship to each other, I prefer to weld or otherwise securely fasten one or morev brackets to the front paneland then to detachably fasten such brackets to the rear panel. One form of such bracket comprises a channel'- shaped member u, the nanges I6 of which may be welded to the rear face of the front panel and I the intermediate portion I1 of which may be disposed in engagement with the inner surface of the back plate. Bolts 4l may then be used for attaching the back plate to the brackets, and to this end the arms of the bracket may hold a spring, fastener 1I, for receiving the threaded ends of the bolts. The fastener may be channelshaped in form, so as to be complementary to the .shape ofthe bracket, and may be held therein against movement by spring tension before the bolts are inserted. The fastener has flexible Y tongues 1I which yield to allow entrance of a bolt in an expeditious manner. Y

My invention, so far as I am aware, has resulted in a range, which can `be completely assembled with enameled parts at the factory and transported in a shipping crate to a dealer without requiring the dealer to set up the range or tighten certain parts to hold the enameled panels together. This has been a marked advance in the range industry for it eliminates the necessity for a dealer to maintain a. service department for the purpose of setting up ranges that are shipped to him in crates. Moreover, the invention has minimized the h'azard of checking and crazing which has always attended the fastening togetherof two enameled parts.
