  • Patent number: 5547407
    Abstract: A first member is pivotally connected to a second member. A rigid support and a linking member are pivotally connected to one another and interconnected between the first member and the second member. The length of the rigid support is selectively adjustable at a constant rate. Adjustment of the length of the rigid support within a first range of length causes the second member to pivot at a first angular velocity relative to the first member. Adjustment of the length of the rigid support within a second range of length causes the second member to pivot at a second, relatively greater angular velocity relative to the first member.

  • Patent number: 4687448
    Abstract: The invention of the present document is an adaptor device (10) for effecting tilting and trimming of an outboard motor (34) mounted to the transom (36) of a boat (38). The device (10) concurrently provides a feature wherein, if the motor (34) engages submerged debris, it is kicked upwardly and rearwardly so that the boat (38) can pass over the debris with minimal, if any, damage. The device (10) includes a base (12) to which are mounted a pair of telescoping cylinders (26). The cylinders include first portions (28) fixedly mounted at the base (12) and second portions (30) which are able to be extended with respect to the first portions (28). The extensible portions (30) pivotally mount transmission links (32) which are, in turn, pivotally mated, at opposite ends from the ends by which they are mounted to the cylinders (26) to the motor (34). The base (12) can be suspended from the transom (36) of the boat (38) by means of a pair of suspension arms (52).

  • Patent number: 4654014
    Abstract: The invention involves an electromechanical mechanism for controlling the trim and tilt of an outboard motor mounted on outboard powered boats. Trim arms are pivotally mounted from brackets attached to a boat transom. The trim arms move the outboard motor prop housing relative to the boat transom and bottom of the boat by use of an electromechanical motor mechanism.
