Abstract: An improved drive mechanism for a windmill has: (a) a drive chain driven into movement by a wind wheel shaft driven into rotation by wind movement against a wind wheel; (b) a drive chain sprocket driven by the drive chain and coupled to a force chain sprocket to correspondingly drive a force chain; (c) a chain pin coupled at one position to the force chain and also coupled to a captive slide; and (d) a pump rod connected to the slide and driven an equal distance in each direction by the driven slide in order to convert full mechanical force equally on both the full upstroke and the full downstroke of the pump rod. The improved drive mechanism improves the efficiency of the power cycle by transitioning to the full upstroke with only a minimal dwell on either end of the stroke for transition to movement in the opposite direction. Full mechanical force can thus be applied equally on both the full upstroke and the full downstroke.

Abstract: A connecting mechanism for structural building system components for supporting radial, compression and tension loads by use of a captive, expanding/contracting jaw assembly which is caused to extended from an opening in the end of the connecting member into a connecting port located in the attaching component. The jaw assembly is then caused to expanded outward and to lock into the connecting port of the attaching component. Operation of the connecting mechanism is performed by causing an operating sleeve, which is located on the outside diameter of the connecting member, to be moved. This causes a structural bond to be made which firmly joins the connecting member and the attaching component. The procedure is reversed for simple removal of structural components or disassembly of the structure whenever desired.
