Abstract

275,696. Turner, E. April 10, 1926. Atmospheric gas and vapour burners; burners for special purposes; vaporizing- apparatus. - Fabrics are singed by means of the products of combustion of fuel burning wholly within an elongated chamber a, formed of refractory material, such as magnesia brick faced with carborundum, and with a longitudinal slot c, through which the products of combustion issue uniformly across the fabric. The slot c may be provided with metal plate h preferably formed of copper or an alloy of nickel, chromium and iron. The fabric may be drawn across in contact with one or both plates h to obtain the additional effect of a plate singeing machine, one of the plates extending above the other or the upper ends of the plates being provided with inclined slots to allow the combustion products to escape. The chamber may be divided into two or more parts, a refractory baffle plate being preferably arranged below the slot c around, or through slots in, which plate the flames pass. The chamber a, Fig. 1, is supplied with gaseous mixture through valve-controlled pipes g and is provided with an opening d for cleaning purposes. When oil is employed, the chamber a is preferably divided into two parts b\ b<2>, communicating through a slot n, Fig. 6, a damper-controlled flue k being provided to allow the combustion products to escape at starting until the chamber is sufficiently heated. A similar flue is provided in a construction (Fig. 10, not shown) for use with producer gas. Specification 169,248 is referred to.
