102	Hand tool with removable extension handle	US944311	1978-09-21	US4232422A	1980-11-11	Ruedi Fellmann
A tool such as a garden cultivator, squeegee, or paint-roller holder has a relatively short handle provided at its rear end with a relatively deep backwardly open recess. An extension handle has a relatively long front end engageable relatively far into this recess and is provided with a fixed ring formed with a multiple screwthread engageable with a similar formation inside the recess so that the two parts can be locked together by a single revolution relative to each other. At its rear end the extension handle is provided with a cap having a forwardly directed end and screwthread formations similar to that of the front and of the extension handle so that this cap can be placed on the rear end of the short handle of the tool if desired.
103	Shovel mounted weed cutter	US38765473	1973-08-13	US3868775A	1975-03-04	ANDERSON ROBERT L
A weed cutter attachment for a round headed shovel blade has a body member in the form of a bowed plate provided with a bifurcated cutting surface on an edge of the plate. Each bifurcated part of the cutting surface is arcuate in plan, and cooperatively meets with the other part to form a substantially V-shaped recess. Clamps are arranged on a concave surface of the plate for selectively, retentively engaging a shovel blade and clamping the attachment onto the blade.
