摘要： An overdraw apparatus supports an arrow for shooting at a support location between the drawstring full-draw rearward position and the drawstring full-forward travel position upon its release. A construction is provided whereby the drawstring can pass through and beyond the support location, and thereby enable much shorter arrows to be shot from a conventional bow than would otherwise be possible. In one embodiment, the actual arrow support includes two members which are separated by a space which allows the drawstring to pass therebetween. In another embodiment, the arrow support includes a pivotally mounted arm which gets struck by the bowstring and pivots forwardly to accommodate the movement of the drawstring forwardly beyond the support location.

摘要： A multiple orifice spray nozzle having reversible orifice cleaning capability for use with high pressure liquid spraying systems. A first embodiment offers selection of a first or second orifice by vertical movement of an orifice selection cylinder. A second embodiment offers selection of a first or second orifice by rotation of the orifice selection cylinder about a vertical axis.
