  • Patent number: 4582601
    Abstract: A basket frame for a traveling water screen includes a pair of hollow parallel lip beams connected together by end plates which are secured to the lip beams by plugs fixed to the ends of the hollow lip beams. The hollow cores of the lip beams are sealed against ingress of water so that the basket frame is buoyant in water. The lip beams are formed of pultruded fiberglass with cross sectional shapes which are provided with complementary curved surfaces so that the adjacent lip beams on adjacent baskets provide a close fitting seal on the vertical run of the basket train and also on the curved section at the bottom of the basket train where the baskets make the turn around the traction wheel.

  • Patent number: 4443126
    Abstract: A clamp strip is bolted to a frame member which may be one side or rail of the basket of a travelling water screen. The strip clamps a margin of the screening to the frame. The strip is of a durable non-metallic material of a high modulus of elasticity and of a general rectangular section. The strip initially is of an arcuate form so that the deformation effected by bolting exerts a force against an extended area of the screening to hold the latter securely. Each strip of one form is secured by a single central bolt. Each strip of another form is secured by two or more bolts including a bolt at each end of the strip.
