Abstract: A lamp socket and light fixture connection wherein the fixture comprises a tube receiving wiring for the socket, the tube having an abutment spaced from one end and an external screw thread on its end portion outward of the abutment, the thread defining a helical groove, the socket being adapted to be slid on the screw-threaded end portion of the tube and carrying a detent which passes by the thread to enable the socket to be slid on the end portion, the detent being engageable in the helical groove for screwing the socket into firm engagement with the abutment with limited rotation of the socket, following the sliding of the socket on the end portion.

Abstract: A dimmer for a fluorescent lamp comprising a ballast inductor and an impedance adjuster for connecting impedances of various values between a power source and one of the lamp filaments, the other lamp filament being connected through a starting switch to the one lamp filament and to the power source. The value of each impedance connected is such that it will allow a current sufficient to start the lamp to pass therethrough. A circuit is provided for increasing the impedance between the inductor and the lamp, upon starting of the lamp, to reduce the current from a level sufficient to start the lamp to a level below the minimum required to start the lamp but above the minimum required to maintain the lamp emission once started, whereby a reduced light intensity level is produced. In another embodiment the ballast inductor has an impedance such as would draw, during starting, a current greater than the maximum rated current capacity of the lamp filaments.

Abstract: Chandeliers having a center column, a circular arm supporting plate attachable to the center column, and a plurality of arms attachable or attached to the plate, the chandelier being adapted to be compactly packaged with said parts in a knocked-down or knocked-down and folded condition, and to be readily set up with the arms in an operative position extending radially outwardly from the plate.

Abstract: A ballast circuit for a fluorescent lamp including a gaseous discharge light bulb which for a given input power produces a decreasing amount of light as the bulb temperature decreases below a designed operating temperature at which the amount of light produced is a maximum, the ballast circuit being adapted to be connected in series with the bulb and having a first impedance at the designed operating temperature.

Abstract: A dimmer switch for a fluorescent lamp having a gaseous discharge light bulb, the switch being adapted to be connected in a ballast circuit including the light bulb and comprising a tapped inductor having a plurality of coil segments connected in series with one another and a plurality of taps or terminals, one at each end of the inductor and one between each adjacent pair of coil segments, with a first one of the end terminals of the inductor being adapted to be connected in the ballast circuit. The switch further comprises a movable switch member for selectively connecting any one of the terminals other than the stated first end terminal in the ballast circuit, whereby, for a given ballast circuit input voltage, the impedance of the inductor as connected in the ballast circuit and thus the ballast circuit current may be varied to produce the desired level of light output of the bulb by adjusting said movable switch member.

Abstract: A lighting fixture adapted to be mounted on a ceiling by attachment to an outlet box in the ceiling. The fixture comprises a pan having a bottom and a rim engageable with the ceiling for spacing the bottom of the pan therefrom, a crossbar attached to the bottom of the outlet box in position extending horizontally across the bottom of the box, and fasteners for detachably securing the rim of the pan to the crossbar. The lighting fixture also includes a first layer of insulation in the pan secured to the pan above the bottom thereof, a second layer of insulation secured on the underside of the bottom of the pan, and a light socket for mounting a light source on the underside of the pan below the second layer of insulation. A diffuser having an open top is mounted on the underside of the pan around the socket and the light source.

Abstract: A method of making a window pane comprising a cut glass panel including a plurality of glass pieces and cames arranged in a predetermined pattern between adjacent edges of the glass pieces and having flanges on both sides of the pane. The method comprises providing a mold having grooving in the pattern of the cames, introducing moldable material into the grooving, allowing the moldable material to set in the mold to form the flanges for one side of the window pane, and removing the flanges from the mold. The glass pieces are positioned on the same or a similar mold with the edges of each glass piece spaced from the edges of the adjacent glass pieces in the predetermined pattern, the spaces between adjacent glass pieces being in register with the grooving.

Abstract: A mounting assembly for a chandelier-type light fixture to be suspended by a chain or the like from a ceiling. The mounting assembly comprises an outlet box open at its bottom adapted to be mounted in an opening in the ceiling, and a crossbar extending beneath the bottom of the outlet box, the ends thereof extending beyond the sides of the outlet box for engagement with the ceiling. Fasteners interconnect the crossbar and the outlet box, the fasteners being capable of developing a clamping force for holding the crossbar in spaced relation relative to the outlet box clamped against the ceiling. A support extends down from the crossbar and has a head at its lower end adapted to be engaged by and to support the chain, the bottom of the head being at a predetermined distance below the crossbar. A canopy is provided beneath the outlet box for covering the bottom thereof, and a ring is provided for releasably securing the canopy to the head of the support.

Abstract: A lighting fixture adapted to be mounted on a ceiling by attachment to an outlet box in the ceiling. The fixture comprises a pan having an upwardly extending rim and a crossbar attached to the bottom of the outlet box in a position extending horizontally across the bottom of the box. The rim of the pan is adapted to be attached to at least one end of the crossbar for mounting the pan adjacent the ceiling.

Abstract: A method of making a cut glass panel comprising a plurality of glass piece arranged with cames in a predetermined pattern between adjacent edges of the glass pieces and having flanges on both sides of the glass pieces. The method comprises providing a mold having grooving in the upper face thereof in the pattern of the cames, introducing moldable material into the grooving, allowing the moldable material to set in the mold to form the flanges for one side of the glass pieces, and removing the flanges from the mold. The glass pieces are positioned on the same or a similar mold with the edges of each glass piece spaced from the edges of the adjacent glass pieces in the predetermined pattern and with the spaces between adjacent glass pieces above the grooving. Moldable material is introduced in the spaces to fill the grooving and the spaces. The previously formed flanges are positioned on the upper surface of the glass pieces so as to engage the moldable material at the top of the spaces.
