发明名称 Garbage chute clearing device
摘要 A device for clearing plugged garbage chutes is specially constructed to make it adaptable for use in multi-story buildings, such as apartment houses, having vertical chutes extending through several stories down to a receptacle in the basement of the building. The clogging of these chutes is generally caused by an accumulation of old newspapers, shopping bags and other large pieces of paper. A device of generally Tee-shaped configuration comprises a series of sharp pointed cutting edges positioned on the cross of the Tee and grabbing arms at either end. An extensible handle comprises the vertical portion of the Tee which in turn is comprised of relatively short sections which may be coupled together to facilitate insertion into the chute to varying elevations. A removable handle is positioned at the lower end of the Tee to permit rotation of the device to effect cutting through the obstruction and pulling out the obstructing material.
