Abstract: Dust removing apparatus includes an air valve operable by a trigger-type push button to permit or interrupt the flow of compressed air from a compressor into an air discharge passage. When the valve is opened, the compressed air flows through an annular slit into the air discharge passage at an increased pressure, producing suction at the inlet of an intake member by an ejecting action. The dust removing apparatus further includes another valve which, when in open position, changes the path of flow of air to force out the compressed air from a nozzle.

Abstract: A system is provided for handling debris, such as twigs, leaves, grass cuttings, refuse and the like comprising a fan-shredding device including a vacuum nozzle, the nozzle being shut off from the fan suction when various units are mounted thereon, such as a hopper and a flexible extension hose. Also, a blower is provided by similarly mounting a cowl on the nozzle and a blower tube on the discharge chute of the fan-shredding device. Shredded debris is bagged in a bag mounted on the discharge chute. On bagging, the shredded debris is compacted by the fan blowing action on the small shredded particles.

Abstract: A manually controlled hand-held air inflator adaptor for use with an air compressor is disclosed which is suitable for molding as a single element and which includes an inlet port and passageway, and discharge and bleed ports and passageways in fluid-flow communication with said inlet port and passageway. The discharge port includes means for attachment to an inflator stem or the like, or the adaptor may be used without the inflator stem, such as for cleaning, etc.
