Abstract: A sectional sickle bar is provided. The sickle bar includes a plurality of elongated bar segments and means for releasably joining adjacent joining ends of adjacent bar segments. The joining means includes a special section and at least three fasteners. Each fastener includes a bolt, a nut and reciprocal thread means for screwing the nut onto the bolt. Adjacent joining ends of adjacent bar segments are joined together by the fasteners and the special section to form a lap joint. In a preferred embodiment, a special fastener having an oblong shank is provided. Preferably, the fastener has an offset threaded end portion for receiving a reciprocally threaded nut.

Abstract: The present invention is directed to a liquid transfer apparatus. The apparatus draws a first liquid from a container to a low pressure region created when a second pressurized liquid is directed through a venturi nozzle. The first and second liquids combine downstream from the venturi nozzle to flow to a destination tank. The apparatus includes a T-shaped conduit structure wherein the pressurized liquid passes through the first or cross conduit. The first liquid in the container is drawn up the second conduit which forms the leg of the structure. A bypass conduit connects between the first conduit near the inlet end and a sleeve surrounding the second conduit. The sleeve includes openings around the periphery such that when valves are appropriately positioned, pressurized liquid is forced out the openings and may be used to flush and clean the interior of the container of the first liquid.
