  • Patent number: 4660493
    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.

  • Patent number: 4574678
    Abstract: A string locking assembly is provided for mounting on the headstock of a guitar or the like between a string nut and tuning pegs. The assembly includes a baseplate that is mounted directly to the headstock. The baseplate includes an outwardly disposed surface for supporting the guitar strings and outwardly extending posts at spaced intervals. The posts separate the individual strings and are sufficiently spaced to allow a wide range of string spacings to pass from the string nut to the tuning pegs through the assembly without interference. The assembly also includes a locking block overlying the strings and the baseplate and an associated cam action lock screw. The lock screw provides an unlocked position to allow quick tuning of the guitar and a locked position to provide clamping pressure between the locking block and the baseplate so as to prevent slippage of the strings over the string nut during play.
