Filed: 1920-10-12
Abstract: 168,263. Stroud, E. Oct. 12, 1920. Reflector-holders.-In an electriclighting fitting in which the lamp may be adjusted relatively to the reflector, the reflector-gallery and lamp-holder are attached to opposite ends of chains or cords passing over pulleys carried by the canopy of the fitting so that movement of the lamp-holder or of the canopy causes the rejector to move relatively to the lamp by an amount equal to twice the distance that the movable member ie moved. As shown in Fig. 4, the lamp-holder a is carried by a sleeve s slidable on a. fixed supporting-tube c surrounding the flexible leads e. Secured to the top of the supporting-tube is a canopy f carrying pulleys or rollers over which pass the chains or cords k attached to the lamp-holder and to the gallery l carrying the reflector m. When the necessary adjustments have been made to bring the lamp into the most suitable position in the reflector, the sleeve s is locked to the tube c by a set-screw u. Fig. 2 shows a. fitting in which slackness in the flexible leads caused by the movement of the lamp-holder is avoided. The lamp-holder is, in this case, fixed to the supporting-tube c which is screwed enternally to engage an internally screwed boss h carried centrally of the canopy f by radial arms g. The reflector-holder l is connected by chains k to a ring o rotatably mounted on the lampholder, the chains passing through slots p in the canopy and over pulleys j carried on the radial arms g. To adjust the reflector, the canopy is rotated about the screwed tube c and the resulting axial movement causes the reflector to be raised or lowered relatively to the lamp by an amount equal to twice the axial movement of the canopy.
