Abstract: A surface-working tool assembly having a surface-working tool connected by a quick releasable coupling to an elongate handle member. One portion of the coupling is connected to the tool and the other is connected to the handle. The tool portion is connected by a universal joint permitting rotational movement about first and second perpendicular axes. A female portion of the connecting means includes first and second telescopically engaged sleeves, the inner sleeve having a tubular passage and radial openings containing locking elements movable into and out of blocking relationship in the tubular passage.
Abstract: Improvements in air blower driven debris collecting devices are disclosed including interchangeable air driven dispenser attachments for dispensing liquids and powders dispersed in an air stream; a debris collector including a portable air blower, a hand held debris pick-up nozzle, and a free standing debris collecting container; and an improved housing construction for a portable blower wherein the air intake and engine exhaust ports are positioned so as not to interfere with the operator carrying the blower and having an integral air cleaner filter holder for the engine carburator.
