Abstract: An adjustable roller chock characterized by a strong, non-fraying strap structure and particularly by a smooth strap formed of a partially flattened tubular member.
Abstract: Disclosed is an improved deck cleat of the type that is mounted on a slide for repositioning along a slide track and wherein the improved construction is characterized by (1) a positioning lock such as a set screw, being placed between the legs of the cleat and (2) by the use of rigid threaded sleeves welded to the slide and serving to receive fasteners, such as screws, which fix the main structure of the deck cleat to the slide. This construction avoids stress being placed upon the fasteners during use of the cleat when stress is applied at the union of the cleat and its slide mechanism.
Abstract: A goose-neck fitting used to form a universal joint between a boat mast and a hollow thin-walled boom or spinnaker pole comprises a tubular socket received into the end of the pole adjacent the mast. The sleeve is suspended in the pole parallel to the pole axis by footings which, with the sleeve, form an H-like truss that extends between the opposite walls of the pole for an appreciable distance inward from the pole end. When in use the sleeve receives a male connector member swivelly mounted on the mast, the goose-neck connection opposes shear forces acting on the pole so as to maintain the pole in the proper orientation with respect to the mast and enable the pole end to withstand the substantial shear forces acting upon it at the point of its connection to the mast.
