Abstract: A combined tiller extension, holding and controlling device for watercraft embodying an elongated tubular member removably attached at opposing ends to a vessel coaming and tiller, and including spring loaded telescoping and detent retained sections whereby the tiller is extensibly operable and is retained on a predetermined course, but permitting of limited lateral deviations therefrom. In addition, manual rotational control of the tubular sections enables finer course rudder adjustment within such a course.

Abstract: The dispensing apparatus is especially adapted for metering, mixing and dispensing small "shots" of synthetic resin material in liquid form with a minute percentage of a liquid catalyst for patching defects in wood panels. A hand-held dispensing gun of the apparatus has a static mix tube extending from a mixing chamber in a dispensing head where a single air-operated piston upon trigger actuation simultaneously opens resin and catalyst infeed ports to the mixing chamber. At the same time, trigger actuation connects a control air line from a source of compressed air to a pilot air line to start an air motor which drives resin and catalyst metering pumps. These pumps are driven from a common drive shaft with an adjustable mechanical linkage for adjusting the catalyst-resin metering ratio. The pumps meter resin and catalyst through separate lines to the mix chamber of the dispensing gun. A thermostatically controlled heater preheats the resin as it flows to the dispensing gun.
