The cylindrical plug of a low-voltage, high current capacity connector assembly has an axially positioned sleeve wiping contact and a transversely positioned U-shaped channel member to provide two pairs of planar wiping contact surfaces parallel to the plug axis and substantially perpendicular to the plug housing surface. The socket component, which will accept standard low-voltage, low current car appliance plugs, includes an internally mounted, closed face pin contact and a barrel contact having depending ears positioned to engage the protruding sides of the plug U-shaped channel member. The socket also has an internal boss and housing lip to prevent electrical activation of a standard automotive cigarette lighter plug, and the plug component of the connector assembly has the sleeve contact recessed to prevent contact following insertion into a conventional cigarette lighter socket. The mobile power tool and appliance operating system includes a portable lead-acid battery pack having a high current capacity socket compatible with existing low current plugs used with appliances intended to operate from automotive cigarette lighter sockets. Matable high current capacity plugs are attached to power tools and appliances through retractable cords. The battery pack is receivable in a 120 VAC powered charging base having a self-contained charging circuit including a transformer and a voltage regulator.

An endless elastomeric vacuum sweeper belt for use in a vacuum sweeper having a diamond pattern drive surface. A first set of ribs project inwardly in a substantially diagonal direction along the drive surface of the belt. A second set of ribs project inwardly along the drive surface of the belt in a substantially diagonal direction opposite the direction of the first set of ribs. The first and set second set of ribs together define a diamond-like pattern on the drive surface as well as a number of particle recesses for the temporary collection of matter. Each rib includes knife-like edge portions to increase the traction of the belt on a drive surface by cutting, loosening and expelling foreign matter lodged between the belt drive surface and the rotation member and/or the drive source of the vacuum sweeper.

A locking device is provided with a faucet spout. The locking device is operable to lock the spout into a fixed position. The spout is rotated by pushing the spout in a desired direction. As the spout is rotated, the locking device locks the spout into a fixed position when the spout reaches a predetermined position.

In one embodiment, a swing spout is provided. The swing spout includes a spout hub and a bearing member. The spout hub is operable to rotate relative to the bearing member. The bearing member has a detent and the spout hub has a detent member. When the spout hub is rotated to a predetermined position, the detent member of the spout hub engages the detent of the bearing member.

A handle for a shower valve has a fixed portion having a first bearing surface and a movable portion having a second bearing surface. A spring biases the first and second surfaces into engagement. The fixed portion includes a chassis that is threadedly attached to a valve body. The chassis mounts an interchangeable lower shell that has a decorative finish or shape. Rotation of the lower shell causes rotation of the chassis for installation or removal of the handle on the valve body.

A mobile power tool and appliance operating system includes a portable lead-acid battery pack having a high current capacity socket compatible with existing low current plugs used with appliances intended to operate from automotive cigarette lighter sockets. Matable high current capacity plugs are attached to power tools and appliances through retractable cords. The battery pack is receivable in a 120 VAC powered charging base having a self-contained charging circuit including a transformer and a voltage regulator. The high current socket housing prevents inadvertent operation with an automotive cigarette lighter plug, and the high current plug housing prevents electrical contact in a automotive cigarette lighter socket, for safety reasons. In another embodiment, the battery pack is provided with two sockets for delivering different power outputs at each respective socket. Recharging of the battery pack can also be accomplished via connection made to one of the sockets.
