Abstract: A novel de-coupling tool for push-fit connectors that employs a novel compression carousel including a parallel pair of clover-shaped discs slidably secured together by a central axle and a plurality of radially-spaced spindles, the discs being spring-biased apart by at least one spring. Each clover shaped disc is shaped with a plurality of radially-spaced open yokes of various sizes for capturing different sizes of push-fit couplings. The compression carousel is rotatable about the central axle to select an appropriately-sized pair of yokes depending on the size of the coupling. Both a vice-grip embodiment and a lever-operated embodiment are disclosed, in both cases that compress the opposing discs together.

Abstract: A wrench with interchangeable, pivotal, rotatable tool pieces on at least one end. A snap-on tool piece, preferably a wrench, fits into a pivotal end piece which is pivotably held to an extension arm by a toothed pin in toothed apertures. The extension arm is pivotably attached to a rotating shaft by toothed pins. There may be another pivotable snapon connection for a tool piece at the opposite end of the shaft. As an alternative, the tool piece fits into a pivotable end piece which is positioned at the end of a pivotably segmented shaft which fits inside the casing and handle of the tool. The location of the tool piece in relation to the handle may be easily set and secured. The multiplicity of possible tool pieces and positions makes this tool highly versatile and capable of reaching into hard-to-reach areas. Thus, bolts in car motors may be reached without having to partially dismantle the motor.
