  • Patent number: 5608303
    Abstract: A rechargeable power pack is shaped and dimensioned to be inserted in the battery compartment of an electrical device. The top of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack houses rechargeable power cells, and has a peripheral wall spaced apart from the sides of the battery compartment mounting the battery contact terminal. Flexible prongs project from the peripheral walls to provide a wiping contact with either a spiral spring negative terminal or a stationary positive terminal of the compartment. A top mounted connector allows recharging of the power pack even while in use on the electrical device. Baffles mounted astride each flexible prong avert damage to the prong during insertion of the power pack into the battery compartment.

  • Patent number: 5163591
    Abstract: A holster to be used by a painter or to suspend a container from his waist has an oblong panel which is suspended from its midsection to the outer face of the belt by a hook-and-ring assembly so that the upper end of the panel is engaged between the belt and the waist of the wearer. The opposite end of the panel has a strap assembly which adjustably surrounds and supports the container. A pair of looping straps secured to the upper and lower edges of the belt at opposite sides of the panel attachment points are use to slidingly engage the arcuate handle of the container. Due to the swinging attachment of the panel to the belt, the holster can be used to carry the container on either the right or left side. During bending or stooping movements the panel automatically adjusts to maintain a vertical position for the container, the friction of the upper end of the panel against the inner face of the belt and the waist of the wearer limits and dampens the oscillation of the container and panel.
