Abstract: Among other things, an open-ended wrench comprises a wrench head defining an opening to receive a work piece. The wrench head comprises a first jaw including at least a first surface to engage with a surface of the work piece, a second jaw including a first curved surface facing the opening, and a plate mounted on the second jaw and movable relative the second jaw. The plate comprises at least a second surface to engage with another surface of the work piece. The plate also comprises a second curved surface engaging the first curved surface and being slidable against the first curved surface.

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.

Abstract: A wrench includes a pair of jaws mounted to a handle. A first jaw is mounted for selective actuation by an actuator between a stationary position with respect to a second jaw so that the jaws engage and rotate the workpiece when the wrench handle is rotated, and a movable position with respect to the second jaw so that the jaws disengage and slide over the workpiece (e.g., in a ratchet-like manner) and allow the workpiece to remain stationary when the handle is rotated. The wrench operates in the selected mode of operation (i.e., driving or ratcheting) when the handle is rotated in either direction. Another wrench (which is not bi-directional) features a pair of plates pivotally mounted within cavities in a pair of spaced jaws on the wrench handle. Each plate includes a grasping surface for engaging a face of the workpiece and a curved peripheral surface which slidingly engages a curved bearing surface in the cavity so that the plate can pivot within the cavity.

Abstract: A squeegee-type cleaning implement has a wiping assembly including a plurality of spaced implements for wiping moisture from the surface to be cleaned, and a handle pivotally connected to the wiping assembly by a hinge. The hinged attachment of the wiping assembly to the handle allows the squeegee to clean the surface (e.g., a window pane) either from top to bottom or from side to side using continuous strokes. The wiping assembly is constructed so that a first one of the implements (which are, e.g., straight blades) precedes a second one of the implements when the implements are wiped over the surface. The first, leading blade is oriented substantially perpendicularly to the surface to maintain the second, trailing blade in contact with the surface at an angle of approximately 45 degrees over the range of travel of the trailing blade across the surface. The blades are spaced by approximately the blade height.

Abstract: An open-end ratchet wrench has a pair of elongated plates that are pivotally mounted to a pair of spaced jaws on the wrench handle and that include at least one elongated surface for engaging a face of a workpiece onto which the jaws are inserted. A spring mounted on the handle biases the elongated plates toward each other so that the elongated plates grasp the workpiece between the elongated surfaces and rotate the workpiece when said handle is rotated in a first direction. The biasing of the spring is overcome when the handle is rotated in a second, opposite direction so that the elongated surfaces of the plates slide over faces of the workpiece (e.g., in a ratcheting manner), allowing the workpiece to remain stationary.
