An apparatus produces a tubular structure having a longitudinal axis and at least one form extending helically inward from the structure relative to the longitudinal axis. The apparatus includes an extruder including at least two spaced apart extrusion die surfaces adapted to extrude plastic state material therethrough. At least one extrusion die has at least one nonplanar channel having facing nonplanar surfaces configured and disposed such that during extrusion of the material through the at least one extrusion die, material flowing into the channel creates the at least one form. The channel surfaces direct material flow such that the at least one form and the structure exiting the extruder and last contacted by the at least one die of the extruder collectively helically rotate about the longitudinal axis.

Apparatus for producing a tubular structure

An extruded multiwall tubular structure formed from extrusion dies, the structure includes a core having a longitudinal axis and a first wall surrounding the core. At least one form extends helically relative to the longitudinal axis and between the core and the outer wall in supporting relationship therewith. At least the first wall and the at least one form lack residual strains, as a result of stress created by the manufacturing process, subsequent the structure exiting the extrusion dies. The core is concentric with the first wall.

A bridge for a conveyor system includes a bridge frame including a top support surface segment having a top support surface. The bridge frame further has first and second side walls extending downwardly away from the top support surface segment. Each side wall has a portion thereof with a radius of curvature substantially matching a corresponding conveyor roller. A portion of the first side wall extends toward and joins the second side wall, the second side wall further having a tail portion and a living hinge extending away from the tail portion.

A lifter assembly includes first and second lifter segments movably attached to one another and defining a lifting channel having an expandable bladder contained therein. Each lifter segment has an arm extending away from a base of the lifter segment and a travel stop at a distal end of the arm. Each lifter segment further has a keyway opening. The keyway opening of the first lifter segment receives the arm of the second lifter segment and the keyway opening of the second lifter segment receives the arm the first lifter segment.

Repeating animal traps incorporating one or more inclined plane trap assemblies with means to preclude an animal on the tilting floor member of the trap assembly from engaging the top and/or side edges of the door member of the trap assembly in an attempt to escape from the trap by pulling the door member down to thereby unblock access to the entrance opening. Additional means are shown to preclude an animal within the enlarged holding chamber or enclosure of the repeating animal trap from engaging the inner end portions of the floor member in an attempt to escape from the trap by pulling the floor member down, enabling the animal to climb onto the floor member and then attempt to pull the door member down to escape from the trap. A barrier in the form of sharpened projections and/or an inclined ramp is provided beneath the inner end portions of the floor member to discourage an animal entering or nesting within that space when the floor member is raised in the reset position of the trap assembly. The barrier can include an inclined ramp whereby the space between the floor member and the ramp is decreased as an additional animal enters the trap assembly, to push an animal beneath the tilting floor member back into the enclosure. A plastic version of the repeating animal trap assembly enables thermoforming of many of the structural elements into the housing cover. Catches are also provided to selectively secure a glue board to the cover of the repeating animal trap to capture an animal attempting to bypass the entrance openings of the trap by running over the trap housing.

Bird food dispenser

A method of making a tubular member such as a bird feeder hopper having offset members extending integrally from the inside surface of the peripheral wall thereof into an internal cavity. A sheet-like member is initially formed with a plurality of wall sections interconnected by integral hinges and the offset members integrally formed on one surface thereof. The sheet-like element can then be folded or pivoted about the integral hinges to form the peripheral wall of the tubular member, with the offset members extending into the internal cavity defined thereby and the edge portions of the end sections secured as by heat sealing, complementary locking members, or a combination thereof.

Method of making a tubular element and product, particularly bird feeder hopper, produced thereby

An animal trap of the type having a base, back wall and side walls made of metal mesh and a roof or lid made of metal sheet. A vertically sliding door is provided at the front of the trap which is held in an upper open position by a trigger mechanism until the trigger mechanism is released by an animal stepping on a bait pan inside the trap. The trap is provided with door slides snap-fitted on the opposite side walls at the front of the trap which improves the rigidity of the trap and the effectiveness of door operation. The slides are extrusions in metal or plastic, each having a first channel which snaps onto the respective side wall and a second perpendicular channel forming a guideway receiving one edge of the door. The roof is formed with inverted U-shaped flanges along its side edges defining a downwardly opening channel adapted to fit over the upper edges of the side walls of the trap housing with inwardly and upwardly extending resilient clip elements pressed into the channel so that the roof can be snap fit over the upper edges of the side walls with the free ends of the clip elements lockingly engaged under horizontal wires of the mesh side walls. The bait pan is supported by a pivot mounting which is spaced inwardly from the side walls of the trap housing and upwardly from the bottom to protect the same against damage causing distortion of the housing.
