Abstract
A dual position cam cleat for use principally on small sailing boats and crafts for maintaining the sail ropes taut. The dual position cam cleat comprises a pair of serrated jaws to grip the rope in either direction. The dual jaws are positioned side-by-side and displaced approximately 90.degree. to 120.degree. apart and mutually pivotable about a common point to either direction. The jaws in a crossdirection comprise a serrated and a non-serrated portion. The non-serrated and smooth portion permits rope slippage for adjusting the tension without movement of the cam cleat. The dual cam cleat is shifted from the one gripping jaw to the other by the sailor vertically jerking the line. A spring means connected between the pivot point and the support member maintains the one jaw in an active position and the other jaw in a passive condition and offers a "crisp" toggling or snapping action when reversing the tension members. A swivel base permits the entire dual structure to be swiveled to any angle within 180.degree. and thereby maintain a constant in-line direction. The dual position cam cleat of the invention provides the unique capability of a continuous line operating a jib or spin…
