Abstract

114,464. Harrison, F., and Russell, J. J. March 31, 1917. Making and repairing lamps; filaments, attaching; supports for.-In mounting a filament within an old or new bulb, a strong temporary support is secured within the bulb near permanent supports, the filament is wound over the temporary support, heated to set it and, if necessary, sinter it, and disengage from the temporary support, which may or may not be then removed. As shown, the temporary support comprises hooks G of pliable or resilient wire to allow of insertion through a hole at the pip end of the bulb. These hooks are fused into a collar on a short glass rod E, which is held in line with the lamp-stem by a wire C and spring clip B, capable of being disengaged from the lamp-stem by a tool which grips tail-levers B<1> on the jaws of the clip. The temporary hooks G are placed near the permanent hooks H so as to facilitate transfer of the filament after setting, or the hooks of the two sets may be so close together that the filament can be wound over both at once, no transfer being required. The ends of the filament are attached to the leading-in wires by coil-springs K. A wire bent to form a crook is used in winding the filament.
