    • 5948. Strode, W. W., and Halston, W. E. March 21. Incandescent lamps.-The connexions of a lampholder are protected by means of a water-tight casing, of porcelain, metal, &c., and also in some cases by means of washers between the parts of the holder and between the holder and its support. In one form, the casing consists of a cup B, Fig. 1, gripped between the upper part of the holder and a flange B' on the support D, a sleeve A threaded at each end, and a flanged ring C which engages a flange F on the cap G and is preferably screwed on the latter. The flange F may be replaced or supplemented by a rubber or like ring, bevelled downwards, the aperture in the ring C being large enough to engage its bevelled edge ; in this case the sleeve A may be integral with the ring C or cup B. Fig. 3 shows a modification in which rubber or like rings K, K are compressed between a flanged sleeve A and the lamp-bulb, and between the sleeve and a nut J, respectively. A washer E is interposed between the porcelain base and the cap of the holder, which is attached, as shown, to a support D, or, by means of a flange and screws to a conduit for the wires, a washer being interposed in either case. When the holder is partly within the conduit, the upper ring K , Fig. 3, is omitted, and the sleeve A screws directly on to the holder ; a ring screwed on the sleeve and bearing against a washer on the conduit presses the sleeve downwards against the lower ring.
