Abstract: A pedal propulsion device for use on a small watercraft, having a lightweight portable frame with integral foot-engagement cranks. A propeller and rudder assembly driven by the foot cranks automatically will adjust for obstacles within and below the water, while maintaining direct drive by utilizing a depth stabilizer assembly extending from the support frame.

Abstract: A shut height adjustment device is provided for a press having press and tooling rams coupled in spaced relationship during a forward stroke of the press ram. The adjustment device includes a carrier defining a rotation axis and a plurality of apertures concentric with the rotation axis. A plurality of spacers are removably held in the plurality of apertures. Each of the spacers extends parallel to the rotation axis between a pair of opposite end surfaces which accurately define a length of each of the spacers. Different ones of the spacers have different lengths. The carrier is rotatably mountable on a post coupled between the press and tooling rams such that the different ones of the spacers may be selectively disposed between the press and tooling rams for engagement by opposed contact portions of the rams during the forward stroke of the press ram.
