  • Patent number: 6454123
    Abstract: A stabilizing caddy for a pressurized gas container includes a base and a housing upstanding from the base. The housing has a cavity defined by a continuous side wall with an upper rim distant from the base and a longitudinal axis extending transverse of the base. The continuous side wall of the housing cavity is uniformly snugly supportively receptive of an outer surface of the pressurized gas container when the pressurized gas container is slidably received therein such that a longitudinal axis of the gas container is substantially parallel to the longitudinal axis of the cavity. The dimension of the housing at the upper rim transverse of the longitudinal axis is substantially less than that of the base. In one embodiment, the housing is substantially conical in shape. In other embodiments, the housing may alternatively be of solid material or of thin wall construction.

  • Patent number: 5839924
    Abstract: A releasable connector for electrically connecting a cable to a generally cylindric battery post comprises a body portion adapted for substantially surrounding and clamping the connector to a generally cylindric battery post and a cable attachment portion connected to the body portion for conducting electricity between the body portion and a cable. The structure of the body portion being comprised solely of a strip of sheet metal configured to create opposed partially cylindrical section shapes with juxtaposed free ends normally inwardly biassed in compression towards one another for clamping about a substantially cylindric battery post.

  • Patent number: 5586919
    Abstract: A connector for quickly clamping onto and releasing from an associated generally cylindrical battery post which includes a unitary metallic body having first and second elongated portions disposed in generally parallel spaced relationship with the first and second elongated portions having respective first and second cylindrical section shaped portions disposed therein in opposed relationship. The apparatus also includes the first and second opposed cylindrical section shaped portions biased toward each other, whereby good electrical contact is made with the associated generally cylindrical battery post. The apparatus also includes an oblong member disposed intermediate the first and second elongated portions which enables the connector to be easily removed from the associated battery post.
