Abstract: Reciprocating floor conveyor include floor slats and slide bearings. The floor slats include a top section, first and second side walls that extend downward from the top section, a first bottom flange integral with the first side wall and a second bottom flange integral with a second side wall. A top section cantilever portion extends laterally outward from the second side wall. A seal flange is integral with the first side wall and includes a seal support surface and a seal flange wall that cooperate with the first side wall to form a seal retainer channel position below the cantilever portion of an adjacent floor slat. The slide bearings have a cross beam, and right and left walls. Wings extend laterally outward from the top of the walls and sit on guide beams.

Abstract: A tubular bladder has an outside wall connected to an inside surface of a finger passage through a band of a finger ring. An inside wall of the bladder is integral with the outside wall and forms a gas chamber. A passage connects the gas chamber to a source of air. Increasing air in the gas chamber reduces the diameter of the finger passage. Reducing the quantity of air in the gas chamber increases the diameter of the finger passage. A valve can be provided to meter air into and out of the bladder. If the bladder is resilient and tends to expand the area of the gas chamber, an air passage can let air into and out of the bladder.

Abstract: The sprayer trailer has a trailer frame with a font end and a rear end. A pair of wheels are connected to the trailer frame. A hitch assembly includes a rear mast with a lower end connected to the trailer frame and a front mast with a front mast top end connected to a rear mast top end. A vertical guide assembly is mounted on the hitch assembly. A hitch connector assembly portion is mounted on a front mast lower end. A vertical guide assembly is mounted on the hitch assembly. A boom support frame is slidable on the vertical guide assembly. A sprayer boom center section is supported by the boom support frame. Nozzles on the boom center section move vertically between a lowered position below the rear mast and a raised position above the rear mast lower end.

Abstract: An adjustable width trailer including a center frame with a center deck, and attached tongue and an attached guide beam that is transverse to the direction of forward movement. Left and right wheel support assemblies are slidably mounted on the guide beam. Left and right tire and wheel assemblies are attached to the wheel support assemblies by suspension assemblies. A left wing frame and a right wing frame, with wing decks are pivotally attached to the center frame, when the wheel support assemblies are in inboard positions, the wing frames are folded. When the wheel support assemblies are slid on the guide beam to outboard positions, the left and right wheels are outboard from the sides of the center frame and the left and right wing frames sit on the adjacent wheel support assemblies and are held in horizontal positions.
