Fresh water rinsing of a boat hull of a boat occurs to remove contamination from the boat hull during each raising operation of the boat utilizing a boat lift. The contamination coming primarily from a body of water in which the boat operate. The contamination, if left on the boat hull while positioned on the boat lift and out of the body of water, will have an adverse effect upon the condition of the boat hull. A series of intermittent burst of fresh water from each fresh water discharge occur through a respective angle of discharge in a respective repetitive cycle of passes during the raising operation of the boat lift. Each fresh water discharge is generally fixedly positioned relative to a fixed portion of the boat lift. Rinsing of the boat cradle of the boat lift also occurs to remove contamination therefrom to reduce adverse effects to the cradle.

A sealing washer providing watertight connection as between electrical conduit parts and including a reinforcing element molded substantially completely within a body of flexible material except for spaced projections extending to a selected surface of the flexible material and serving to locate the reinforcing element accurately within the body of flexible material during the molding process.

Metal reinforced sealing washer

A one-piece sewing machine bed extension including portions which deform as the extension is placed on a sewing machine and generate internal stresses coacting with interlocks between the bed extension and sewing machine so arranged as to firmly secure the bed extension in place in a manner which is augmented by forces applied to the bed extension incident to normal operation and handling of the sewing machine.

Sewing machine bed extension

A sewing machine bed having main and open channel sections is molded of glass reinforced thermosetting plastic composition which is injected into the mold through a side gate located opposite the juncture of the main and channel sections providing advantageous fiber orientation resulting in dimensional stability and freedom from warpage.

Method of molding a sewing machine frame of fiber reinforced composition

A sewing machine bed which, because an open channel is required to accommodate a preassembled operating mechanism module, is reinforced to minimize objectionable deflection by reinforcing ribs formed on a cover plate and rigidly connected to reinforcing bosses on the sewing machine bed when the cover plate is secured thereon.
