Abstract: An actuator mechanism is defined by a lever arm that is integrally connected to resilient spring members. The lever arm is movable between first and second positions and is normally biased into the first position in which the actuator may engage an adjacent member, for example to provide a fluid-tight sealing relationship of to lock the adjacent member in a stationary position relative to the lever arm. Movement of the lever arm into the second position releases the engagement with the adjacent member. In one embodiment the actuator is defined by a pair of overlapping, oppositely oriented slots cut into a monolithic member to define both the lever arm and the spring members. The lever arm rocks in a teeter-toter fashion when actuated and both ends of the lever arm can be utilized to perform work.

Abstract: A unique golf putter clubhead, when attached to a shaft, assures better directional control of a golf ball travel when use for its primary purpose of putting a golf ball. The putter clubhead is formed along a longitudinal axis generally transverse to the plane defined by the ball-striking face. The ball-striking face may be formed in a radial surface defining either a spherical or cylindrical arc.
