    Abstract: An apparatus for retaining and storing swimming pool maintenance equipment such as brushes, net scoops, tubular handles and extensions, bottom vacuum heads, flexible hoses and the like when not in use. The apparatus is releasibly connectable, preferably by spaced suction cups, to a top surface of a horizontal frame member of a swimming pool cage or screened enclosure, the frame member being elongated above the pool deck and typically having a rectangular tubular cross section of thin wall aluminum. A plurality of spaced brackets of various configurations are connected to the elongated support bar to which the suction cups are also connected, whereby the maintenance equipment is supported and stored.

  • Patent number: 5224642
    Abstract: A pull wheel for a form, fill and seal pouch packaging machine has a hub that includes an axially extending central bore and a circumferentially extending peripheral surface that is located radially outwardly from the bore. First and second circumferentially extending flanges are formed integral with and extend radially outwardly from the peripheral surface of the hub. The first and second flanges are axially spaced apart one from the other on the peripheral surface of the hub forming a groove between them. An integrally formed, annular shaped elastomeric body is located radially outwardly from the hub in part within the groove and in further part over and radially outwardly displaced from the first and second flanges such that the periphery of the elastomeric body is displaced radially outwardly from the periphery of the flanges.
