Abstract: The automatically adjusting gripping device grips a workpiece ever more tightly as greater torque is applied thereto. The device has a base plate having a linear guide slot or series of radial guide slots, with a pair of jaws residing in each slot. A torque application component rotates relative to the base plate, and has a cam track of varying diameter in which the heads of the jaws ride. Rotation of the torque application component and cam track relative to the base plate causes the jaw heads to slide along the track due to the jaws being captured within the base plate slot, thereby changing the span between jaws as the cam track diameter varies at the jaw head locations. The gripping device is useful as an adjustable wrench but may be applied to other environments as well, e.g., as an automatic gripping and releasing device in conveyor systems, etc.

Abstract: A ratcheting adjustable wrench is disclosed. The wrench has a main body defining a wrench head, handle and fixed jaw. The main body is fabricated of hardened sheet metal formed from laminations. The adjustable wrench has a pin/slot guide mechanism to retain and provide position adjustment for an adjustable jaw. A locking mechanism allows the adjustable jaw to ratchet over the corners of a fastener being tightened. In a locked position, the wrench operates like a standard adjustable wrench. Moving a trigger to an unlocked position allows the worm gear mechanism to shift axially for additional travel. The movable jaw engaged to the worm gear is thereby also allowed to shift position so that the adjustable jaw wrench can rotate over the points of the fastener being torqued.

Abstract: An adjustable wrench has a ratcheting feature by which its movable jaw retracts away from its fixed jaw when the handle is pulled in one direction, enabling the wrench to slip over the facets of a polygon-shaped nut, but which locks the jaws in position when the wrench handle is turned in the opposite direction. A jaw adjustment screw is positioned for rotation in the wrench head and is axially movable with the lower jaw, but only when a support wedge is slidingly retracted out from its normal position supporting the bottom end of the adjustment screw. The tool can have a ruled edge adjacent to the jaw for indicating jaw opening size. Another feature is a slidable fence device on the fixed jaw, to be moved slidably over a face of the nut when the wrench is in place, providing a stop against sliding of the wrench off the nut.

Abstract: A tool tip is inserted from the inside of the tire into a hole in a tire crown by turning the tool tip as it is pressed against the tire. The tool tip is mounted on a hollow tool having a cylindrical insert receiving chamber. An insert is pushed by a plunger out of the receiving chamber in the hollow tool through a tapered portion into a compression chamber in the tool tip. The compression chamber has a diameter smaller than the diameter of the insert so that when the insert is ejected from the hollow tool it will expand to fill the hole in the tire. The insert is also tapered to engage the tapered portion between the receiving and compression chambers. The plunger has a plunger head with a substantially flat pushing surface and knurled edges which the operator can manually grip and push.
