Abstract: 297,043. Austen, F. H. May 9, 1927. Radiators.-In central heating (or cooling) radiator systems and apparatus, of the kind in which radiators are mounted behind wall or ceiling surface elements, or behind applied panellike sheets or " veneers," which form the radiating surfaces, detachable securing means are provided within the area of the radiator unit and are adapted to fix the veneer evenly and maintain it in heat-transferance relationship with the radiator. Warping of the sheet or veneer is thus prevented, and accessibility to the radiator is provided for. Fig. 2 shows a radiator arranged in front of a wall and having secured to the front face a veneer 2 forming a dado. The veneer is provided with integral or attached clips 20 having inclined portions engaging the edges of slots 34 in the front of the radiator, the veneer -being- removable on lifting. The edges of the veneer are held, with provision for expansion, under mouldings 5, and heat-insulating material 6 is preferably provided round the margin of the space containing the radiator. In a similar manner radiators may be arranged behind veneers forming a false front to a wall, the face of which may be recessed partially to accommodate the radiator in order to economize space. New walls may be formed with recesses 7, Fig. 5, to accommodate the radiator, the veneer 2 meeting the plaster 8 and the joint being covered by moulding 5. The sides, or sides and back, of the recess may be lined with heat-insulating material 6. Similar constructions are described in connection with radiators mounted between ceiling joists, Fig. 10, showing a form in which the radiator is suspended from the joists 10 by adjustable bolts or links 13, the veneers being secured to distance pieces 11 on the underside of the joists; in a modification, the radiators are similarly suspended from a supplementary slotted box girder secured to the underside of the joists. The clips 20 for securing the veneer are preferably of spring metal arranged to exert a wedging action; they may engage parts of the radiator, or may extend, between radiator units or through slots therein to parts or wall brackets positioned to receive them; they may also. be provided, in addition, outside the area of the radiator. The veneers may also be secured by screws passing through apertures in a radiator, or between adjacent radiator elements, into plugs &c. in the wall. The use of engaging studs and keyhole slots on the veneers and radiators is also referred to. The veneers themselves may be of any material, such as sheet metal, plywood, stone or mineral substance, cement asbestos sheeting, or composition boards; or they may be of a composite nature, for example, a base of metal with a covering of wood, paper etc.; they may also be formed from an expanded metal or like support to which plaster is applied in situ. Non-adhesive composition, which may comprise a, metallic filling, may be used for bedding the veneer on to the radiator. The radiators may be of flat box form, cast integrally or in parts, or of welded sheet metal, with flanges for securing to the wall, and with slots or cavities for receiving the clips which attach the veneer; electric radiators of refractory material are provided with similar slots or cavities. Figs. 21 and 22 show a, suitable form of cast radiator comprising fluid ways 31 of triangular or D section united by web members 32 and connected to headers 33, one face of the radiator being a plane surface. Slots formed in the web provide bar members 35 which may be engaged by the clips securing the veneer. Radiators may also be formed of bent piping of D or other flat-sided section providing a flat face adjacent the veneer; the pipe coils may be welded or cast in one with a facing plate. The radiators may be resiliently mounted in relation to the veneers in the manner described in Specification 298,069. Theback of the radiator may be exposed in order to heat an adjacent room or passage. The invention may be applied to radiating devices imitating articles of furniture.
