Abstract: A wrench 10 including first 11 and second 12 jaw members each having first and second gripping portions 23 for gripping an article to be rotated about a work axis and a leverage portion spaced from the gripping portion, has one or two handles, one handle 13 being connected to the leverage portion of the first jaw member for pivoting movement relative thereto about a leverage axis parallel to the work axis and the other handle 29 (where provided) extending from the leverage portion of the second jaw member in the plane of rotation of the first handle, and an engagement mechanism on the handle for movement therewith for engagement with the leverage portion of the second jaw member to urge the first and second leverage portions apart, and a connector 14 connecting the first and second jaw members and holding them in opposed disposition, the connector being operatively interposed between the respective opposed gripping portions and the opposed leverage portions and being arranged to allow pivoting of the jaw memb

Abstract: Wrench apparatus for rotating a body about an axis and including a jaw assembly having opposed jaw members, a lever assembly having lever means pivotally connected to one jaw member, and abutment means associated with an inner portion of the lever means and cooperable with the opposing jaw member for urging the jaw assembly into tight engagement with the body to be rotated upon rotation of the lever assembly about the axis of the body. The abutment means is adjustably engageable with the lever means whereby the operative position of the lever means relative to the jaw assembly may be selectively varied. The abutment means closes across the open end of the jaw assembly and is moveable independently of the lever assembly between an engage closing position and an open position at which the jaw assembly can be accessed through its open end.
