Abstract
A portable unitary apparatus, preferably wheeled, is provided herein for disposing of hazardous light bulbs, e.g., fluorescent light bulbs. The apparatus is in the form of a housing which includes an upper compartment, and a lower compartment. The top of the housing is provided with a cylindrical fluorescent light bulb feed chute for a fluorescent light bulb to be disposed of. A rotary, bulb crushing fluorescent light bulb device, comprising a pair of rigid articulated crushing hammers is secured to opposed ends of a securement member, by means of a chain-type joint, each rigid articulated crushing hammer including an arm and a weighted end, the weighted end being secured to the end of an associated arm by a chain-type joint. The rigid articulated crushing hammers which are powered by a motor, are disposed within an enclosed reduction chamber shroud which depends from the upper compartment. A disposable, pulverized fluorescent light bulb collection bag is selectively disposed within the lower compartment in air-sealed relationship to the reduction chamber. A filter system is disposed within the upper chamber. This filter system includes exhaust tubes which are connected between the…
