Patent number: 9550628Abstract: A module for a modular conveyor belt includes a flexible retainer for retaining a hinge rod in a bore of the module. A stopper limits the bending movement of the retainer and supports the midportion of the retainer to prevent stresses generated in the retainer from exceeding its design stress.Type: GrantFiled: December 23, 2008Date of Patent: January 24, 2017Assignee: Laitram, L.L.C.Inventor: Philip J. Wunsch

Patent number: 8453827Abstract: A modular spiral belt and method for molding belt modules for constructing a heat-resistant belt. The spiral belt is constructed of a series of hingedly interconnected belt modules. The modules have single hinge links at the outside of a turn and dual hinge links elsewhere. All the hinge links extend outward from opposite faces of a central transverse spine. The dual hinge links, which each have a pair of parallel legs joined at a distal end by a yoke, are separated by a transverse pitch greater than the transverse pitch of the single one-legged hinge links at the outside of a turn. When molded from a blend of a thermoplastic polymer and a nanoclay, belt modules are useful in heat-resistant applications without sacrificing beam stiffness.Type: GrantFiled: October 28, 2009Date of Patent: June 4, 2013Assignee: Laitram, L.L.C.Inventors: Andrew A. Corley, Daryl J. Marse, Dax Wilson-Boyer, Philip J. Wunsch

Patent number: 8453825Abstract: An intermediate drive system for driving a conveyor belt with one or more intermediate drive belts. The intermediate drive belt includes lateral rows of pivotable teeth spaced apart along the length of the intermediate drive belt. The teeth extend into the conveyor belt along a portion of the carryway to drive the conveyor belt in a conveying direction. The only component external to the intermediate drive belt that the teeth contact is the intermediate drive belt. Engagement and disengagement of the teeth with the conveyor belt is effected without the use of cams against the teeth.Type: GrantFiled: September 17, 2010Date of Patent: June 4, 2013Assignee: Laitrom, L.L.C.Inventor: Philip J Wunsch

Patent number: 7776212Abstract: A boot seal for a vertically traveling water screen and a method forming a boot seal. The boot seal comprises a bent plate that extends from an attachment end to a free end. The attachment end is attached to a frame mounted at the bottom of a channel of water flowing through the water screen. The boot seal is positioned just upstream of the upward-moving upstream face of the water screen. The free end of the bent plate in a rest position is positioned close to or lightly touching the upstream face of the water screen. The bent plate has a concave surface facing the water screen. The bent plate acts as a cam follower to a passing lift element's cam. As the lift element slides along the concave cam surface, the lift element pivots the boot plate in an upstream direction against a spring bias. When the lift element clears the boot plate, the boot plate springs back to its rest position.Type: GrantFiled: March 14, 2006Date of Patent: August 17, 2010Assignee: Laitram, L.L.C.Inventors: Philip J. Wunsch, Gilbert J. MacLachlan

Patent number: 7393451Abstract: A compressible boot seal for sealing the side of a vertical traveling water screen with flights. The boot seal is formed by a U-shaped, bent nylon plate having a bottom base that resides in the boot section at the lower end of the traveling water screen and two upwardly extending arms that are attached at their distal ends to a side of the water screen support. The plate is bent at the intersection of the base and the arms to form a living hinge that allows the plate to deflect toward the side of the support on contact with side edges of the flights. The hinge seals the plate against the side edges of the flights. A resilient filler material fills the void between the plate and the side of the support to prevent sand and debris from interfering with the deflection of the side seal.Type: GrantFiled: October 9, 2006Date of Patent: July 1, 2008Assignee: Laitram, L.L.C.Inventors: Philip J. Wunsch, Rocky Portillo
