  • Patent number: 4473918
    Abstract: Handle includes a main handle portion and an outer end portion pivotally connected thereto. Both the main handle portion and outer end portion have connecting members extending from the adjacent ends thereof, with offset flanges thereon in overlapping engagement with each other and connected together by a bolt and nut arrangement. The opposed faces of such offset flanges have radially extending teeth in mating engagement with each other positively to retain the outer end portion in any desired adjusted position from straight out in line with the main handle portion to approximately 90.degree. in either direction or anywhere in between upon loosening and retightening the nut.

  • Patent number: 4364144
    Abstract: A duster head characterized by a central sleeve portion made from a strip of open mesh backing material, and a plurality of spaced apart longitudinally extending rows of yarn fringe material stitched thereto. To make the duster head, initially two inside rows of the fringe material are stitched to one side of a flat strip of the mesh backing in spaced relation from each other and from the edges of the backing before the backing is formed into the desired cylindrical shape. Both inside rows may extend almost the entire length of the backing material, terminating a short distance from each end thereof. However, preferably one of the inside rows is continued to the adjacent side edge of the backing near the upper end thereof to ensure more complete coverage of the backing by the fringe material in that region. The bottom raw edge of the backing is then serged to give it added strength.

  • Patent number: 4345351
    Abstract: Extension handle consists of a pair of telescoping handle parts made out of relatively thin-walled plastic tubing. A protrusion on the outer wall of the inner tubular member, formed as by inserting a pop rivet therethrough, frictionally engages the inner wall of the outer tubular member to provide some drag or resistance to axial movement of the tubular members relative to each other. The outer tubular member, being made of relatively thin-walled plastic tubing, will deform more or less according to the amount of interference between the rivet and inner wall of the outer tubular member. A rigid metal or plastic ring at the inner end of the outer tubular member acts as an abutment or stop for the protrusion on the inner tubular member thus preventing the telescoping handle parts from being completely pulled apart.
