Definitions
- My invention relates to electric incandescent lamps and similar devices which comprise a filament supported within a bulb or other container. More particularly, my invention relates to devices of that character which are subjected during use to forces causing considerable vibration of the filament and its supports. The object of my invention is to render the filaments of such devices less responsive to forces tending to their maximum amplitude of vibration at their free ends and a comparatively small amplitude at the points of engagement with said filament.
- Fig. 1 is an elevation of an electric incandescent lamp embodying one form of my invention
- Fig. 2 is an elevation at right angles to that of Fig. 1
- Fig. 3 0 is a fragmentary elevation
- Fig. 4 is an elevation at right angles thereto of a modification.
- the incandescent lamp shown in Figs. 1 and 2 comprises the glass bulb 10 within which is supported a filament mount comprising a glass stem 11, a central glass rod 12, and the leading-in conductors 13 which are sealed at 14 in the stem 11 and are electrically connected to leading-in supports 15 7 each having one end embedded in the stem the leading-in and other supports will have lamp, astem and a plurality of combined leading-in conductors and filament engaging supports extending from said stem, the free ends of said supports each projecting beyond the point of engagement with said filament to damp the vibrations oi the filament.
