208,366. Harbord, A. E. Dec. 7, 1922. Atmospheric vapour burners; vaporizing- apparatus; burners, mounting; flame spreaders and deflectors.-A vapour burner comprises a tube 5, provided at its lower end with a series of superposed perforations 13 and at its upper end with a nipple regulating - needle 7, and adapted to be reciprocated by an eccentric pin on a transverse shaft, liquid fuel passing from a reservoir 4 through the tube 5, perforations 13 and the lower vaporizing section of a burner tube 6 to a nipple 8. The upper mixing section of the tube 6 is surrounded by a concentric tube 15 having air-inlets 16 and supported by an annular flanged member 14 secured to the tube 6. Two air-inlet tubes 17 pass through the tube 15 and are brazed to the tube 6 adjacent the nipple 8. A disc 18 having an upstanding flange 18<a> is secured to the upper end of the tube 15 and a depending flange 19a of a plate 19, provided with two annular series of burner outlets 20, rests on the disc 18, an annular plate 24 being mounted by means of indentations 24<a> in its surface on the disc 18 so that an annular flange 24<b> projects into the space between the tubes 6, 15. A spreader disc 21 having an upturned rim 21<a>, which shields the inner ring of perforations 20 is secured by a screw 23 on the plate 19. A starting cup 25 is provided. The Provisional Specification describes also a modified construction in which the burner head comprises a cylindrical inverted cup, having a ring or rings of perforations in its top face and a plurality of perforations in a reduced bottom flange, which is located within an upstanding flange of an annular base section mounted at the upper end of the burner tube. The inner part of the base section is provided with air inlets and an inner circular flange in which is screwed an inverted cup having a circular aperture at its upper end and forming a mixing- chamber.
