  • Patent number: 5769336
    Abstract: A portable unitary apparatus is provided herein for disposing of hazardous light bulbs, e.g., fluorescent bulbs. The apparatus includes an open-topped, multi-compartmented container of circular cylindrical cross-section, having three compartments and a hinged covering lid. The lower surface of the lid is connected to a reduction chamber, having an axial inlet means for a bulb to be pulverized and an axial outlet leading directly to the collection compartment. A rigid unitary pulverizing blade is secured to the drive shaft of an electric motor. A light bulb feed chute extends through the lid, and extends from above the lid to the reduction chamber. A disposable pulverized light bulb collection bag is selectively-disposed within the collection compartment in air-sealed relationship to the axial outlet means of the reduction chamber. A vacuum motor is operatively-disposed within the lower exhaust chamber.

  • Patent number: 5660338
    Abstract: Apparatus is provided herein for disposing of light bulbs, e.g., fluorescent bulbs. The apparatus includes an open-topped cylindrical container covered by a removable lid. A hollow cylindrical light bulb feed chute is perpendicularly attached to, and extends through the lid along the central longitudinal axis of the lid and has an inlet opening which is and an outlet opening disposed below the lower surface of the lid. An electric motor is mounted upon the upper surface of the lid and has a downwardly-extending rotatable shaft, projecting through the lid and terminating below the lower surface of the lid. An "on-off" electrical switch operates the electric motor. Inventive structure is provided for pulverizing a light bulb, e.g., a fluorescent tube, as it emerges from the outlet opening of the feed chute. That structure comprises a hub at the terminal end of the shaft. At least two equiangularly-disposed, multi-stranded, braided, wire cables are secured to the clamp.
