Abstract: 23,816. Warburton, T. Nov. 3. Reflectors and holders therefor.-In reflecting- apparatus for incandescent gas lamps, reflectors similar to those described in Specification No. 11,971, A.D. 1903, have their metal backs made with one loop or slot a, Fig. 1, to which the cramp b is pivoted. A metal strip c has its ends c<1> bent round the arms of the cramp, and is provided with a screw d for adjusting the inclination of the reflector. The cramp may be substituted by a metal plate arm which may be pivoted, detachably or otherwise, or riveted, or attached by studs and slots to the reflector. The arms or cramps of two or more reflectors may be attached to a ring which fits over a shoulder on the lamp chimney, or which may be flanged to fit on the upper edge of the chimney ; or the upper ends of the arms may project inwards and hook over the upper edge of the chimney. Or an annular reflector may be provided with arms with or without a ring as above. Annular reflectors may be composed of segments, the edges of the back being lapped over the edges of the glass. A ring with both edges turned outwards may also be fitted on the inner edge, and the ring may be provided with tips to rest on a plain ring holder, or the holder may be provided with the tips. Rings are fitted on the inner and outer edges of moulded glass reflectors with circular edges. A special holder is made of two rings n, o, Fig. 4, and two rods p. The upper ring is preferably flanged to carry a reflector without tips, or the reflectors may be attached by any of the other methods. The lower ring is also flanged to facilitate its passage over the chimney gallery, on which it rests. Or the holder may consist of a ring or collar which fits on or over any part of the burner, or a tube which is inserted between the gas nipple and the mixing-tube, the ring or tube being provided with arms which support the ring. The ring encircles the chimney or globe of the lamp and supports the reflector. Or the ring which supports the reflectors may be provided with clasp or grooved pieces by which it is attached to the wire holder of an anti-vibration device. Or the reflector may have grooved pieces, braces, clasps, clips, or the like which engage the lamp-holder, smut-catcher, or other part. Arms with hooked ends may be pivoted to the ring to attach it to the globeholding ring of an inverted lamp ; or the arms may be made of spring steel and riveted to the reflector holder. Pinned arms slide in slots at the back of the reflector in attaching it to, or detaching from, the globe-holder. The reflectors are preferably supported so that their inner edges are level with, or below, the top of the mantle. The arms are bent, if necessary, to allow a passage of air between the reflector and the chimney. Paper &c. may be placed between the back and the glass of the reflector to absorb damp. With circular reflectors may be used a holder of the ordinary type having a large ring with aninturned edge for supporting the outer edge of the reflector. The small reflectors, Fig. 1, may have an additional slot at the back to which a safety-guard may be connected. Opal, metal, or enamelled reflectors may be employed instead of silvered glass. The lower ring which fits round the chimney gallery may be secured in place by a screw, or the ring may be cut and the ends turned outwards to form lugs, a screw being fitted in the lugs to tighten the ring. The lower ring may be substituted by a sleeve which fits on the mixing-tube, the sleeve having apertures which admit air to the mixing-tube ; or it may be substituted by a washer or the like countersunk to fit on the shoulder of the mixing- tube ; or a nipple may be employed, one end of which screws into the mixing-tube, and the other into or on the nipple of the gas pipe or pendant.
