Abstract: A tool for removing and installing an oil plug of an internal combustion engine comprising a handle, a drive shaft and a tool head. The drive shaft comprises a flexible material suitable for providing improved access to hard to reach oil plugs. The flexibility of the drive shaft also provides a means for limiting torque transmission between the tool and the oil plug, thereby preventing accidental overtightening, and consequent damage to the oil plug. A multitude of tool head designs are also envisioned by the inventor. Each tool head is designed to frictionally engage and retain the oil plug within the tool head during the installation and removal process allowing for easy, single-handed use of the tool during the servicing and repair of an internal combustion engine.

The method includes extracting a bead from a mounting groove of the rim, so as to bring it axially outside a seat of said rim, with a view to subsequently mounting that bead on the seat, the other bead having been mounted on another seat. The method further includes bringing the bead into a local extraction position, radially and axially outside the seat, and of extracting the bead on the whole circumference of the tire, by pivoting a bead gripper on two pins provided radially on both sides of the mounting groove of the rim. The device includes a bead gripper pivotally mounted on one of the pins which is mobile and coupled to a control through a rod which is pivoted on the other pin.

Abstract: A wrench adapter assembly is provided that can adapt a conventional manual or power wrench to be used to grasp and rotate a smooth-surfaced cylindrical object. The wrench adapter assembly includes of a pivoting hook, a biasing means for the hook, a wrench adapter with a multisided flange for engaging the jaw of a wrench and a concave jaw. The pivoting hook is in circumferential alignment with the concave jaw so as to receive a smooth-surfaced cylindrical article. The flange shoulder has sides that match up with the sides of the jaw of the wrench. Once the wrench adapter assembly is secured within the wrench jaw, it may receive and hold a smooth-surfaced cylindrical article. The wrench adapter rotates with the jaw of the wrench. Thus, the wrench may be used in combination with the wrench adapter assembly to rotate smooth-surfaced cylindrical articles.

Abstract: A wrench has a pair of jaws that are disposed on a handle and are spaced to define an opening for a workpiece. A pair of plates, each of which includes a workpiece engaging surface are mounted on the jaws for selective movement between first and second positions. In the first position, the plates are immobile with respect to each other so that rotation of the handle in a first direction causes the plates to grasp the workpiece between the engaging surfaces and turn the workpiece in the first direction. In the second position, a first one of the plates is pivotable with respect to a second one of the plates so that rotation of the handle in a second, opposite direction causes pivoting of the first plate and allows the engaging surfaces to slide over the workpiece, thereby allowing the workpiece to remain stationary.
