Abstract: An improved sewing thimble having an elongated, tubular body consisting of a pliable material, such as rubber, wherein a plurality of vent holes are disposed about the annular body portion, the inner bore thereof being designed to conform to the average finger, including those having extended fingernails. The forward head portion of the thimble is enlarged with a thickened area of a hard rubber or plastic to allow for forceful engagement with a needle to be threaded. Alternative arrangements include a protective shield embedded within the head portion and a threading-and-cutting device mounted to the thimble at the tip of the enlarged head thereof.

Abstract: A non-snagging fishing sinker comprising a flexible plastic bag having at least three sides defined thereby, wherein one side is open to allow various weight-providing materials to be placed therein, preferably wet sand. Disposed along and adjacent to the open side are a plurality of holes to receive a wrapping wire which is provided with an eye hook to be attached to a conventional fishing line. There is also formed adjacent and below the holes a weakened area, whereby the lower portion of the bag can be easily separated from the fishing line when the sinker is snagged; that is, the bag is allowed to tear along the weakened area.

Abstract: A timing device in combination with a thermostatic control whereby heating units of the type used for heating structures such as buildings can be automatically turned off during predetermined periods, as when such buildings are unoccupied, the device comprising a clock-like motor coupled to a plurality of cam discs adjustable about the output shaft of the clock mechanism, the cams including cam heads to operate control switches engaging therewith.

Abstract: An underwater timer and release device comprising a cylindrical housing sealed at its opposite ends and adapted to receive a slidable spring-loaded piston therein. The piston includes a metering orifice to provide a regulated flow of fluid from a secondary chamber to a primary chamber, thereby actuating a releasing means when the piston shaft is disengaged from a locking means and is allowed to operate. Releasably secured to the housing is a float marker, which rises to the surface of the water, having an interconnecting cord attached to the submerged housing. A one-way check valve is also disposed within the piston, whereby the fluid can be transferred back into the secondary chamber for reloading the release means.
