摘要： A reversible ratchet wrench has a wrench handle with a circular ratchet head having a cylindrical array of ratchet teeth and receiving coaxially rotatably therein a drive body. A pawl is carried by the drive body for movement between forward and reverse conditions of engagement with the ratchet teeth, being retained in each of these positions by an over-center spring engageable with a pin on a reversing lever disposed coaxially with the drive body and retained thereon by a bushing and a screw for rotation relative to the drive body and the ratchet head for shifting the pawl between its forward and reverse conditions. Indicia on the bushing and the reversing lever cooperate to indicate the condition of the pawl.

摘要： A speed wrench has a short jaw and a long jaw interconnected by a throat, the jaws respectively having short and long driving surfaces which are generally parallel but which may be very slightly inclined with respect to each other. The throat has a generally flat surface portion adjacent to the short driving surface and inclined at an angle of at least 120.degree. thereto and connected thereto by an arcuate recess in the short jaw. This generally flat surface portion may be slightly convex having a radius greater than twice the distance between the driving surfaces. The remainder of the throat is arcuate and is shaped and dimensioned so that it will not contact a fastener engaged with the driving surfaces. Open-end wrench and adjustable wrench versions are disclosed, and in the former the support surface portion of the throat has a length approximately one-half the side dimension of an associated fastener. In the adjustable wrench version, at least the long driving surface may be serrated.

摘要： A ratchet wrench is provided which includes a ratchet head having a part-cylindrical surface with head teeth thereon and an elongated handle hingedly coupled to the head. The handle has first and second handle ends, an axis extending between the ends and an axial first bore opening at the first handle end. The wrench also includes a rod disposed in and moveable within the first bore between an engaged condition engageable with the head teeth for locking the head in a selected position relative to the handle and a non-engaged condition disengaged from the head teeth and accommodating relative movement of the head and handle, and biasing structure for biasing the rod to the engaged condition. The wrench also includes retaining structure coupled to the rod for retaining the rod in its non-engaged condition. The retaining structure may be disposed at several locations relative to the ratchet head.

摘要： A socket drive tool includes an elongated shaft having a coupling structure for coupling to a socket. The coupling structure includes a detent ball disposed in a detent recess and moveable between retaining and releasing positions relative to the socket. The shaft has a cavity therein communicating with the detent recess. A tubular sleeve having a sleeve cam surface is disposed coaxially about the shaft for movement between a retaining condition and a releasing condition. A rod is moveable axially between retaining and releasing conditions, being spring-biased to the latter. The rod has within the cavity a first cam surface engageable with the detent ball and a second cam surface engageable with a transfer ball which is, in turn, engageable with the sleeve cam surface. When the sleeve is in the retaining condition, the sleeve cam surface causes the transfer ball and rod to hold the detent ball in its retaining position, and when the sleeve is in the releasing condition it causes the transfer ball and the rod to permit movement of the detent ball to its releasing position.

摘要： A wrenching member includes at least two spaced-apart and substantially oppositely facing drive surfaces, each of which has a roughened region and an unroughened region thereon, with the roughened region being disposed adjacent to one end of one of the drive surfaces and adjacent to the other end of the other drive surface so as to afford a differential driving arrangement which exerts a greater frictional wrenching force in one direction than in the opposite direction.

摘要： An adjustable wrench having locked and unlocked conditions is provided. The wrench includes a wrench body including a fixed jaw, and a movable jaw slidably mounted on the wrench body. The wrench body includes first and second contact walls, the second contact wall having a wall cam surface. The wrench also includes an adjuster assembly including a worm gear on the body between the contact walls and threadedly engaged with the movable jaw for moving the movable jaw toward and away from the fixed jaw, and a locking disc disposed between the worm gear and the second contact wall and having a disc cam surface engagable with the wall cam surface of the second contact wall. The locking disc is movable by a user's finger between the locked and unlocked conditions, wherein the disc cam surface engages the wall cam surface in the locked condition for wedging the adjuster assembly and the locking disc between the first and second contact walls to substantially prevent rotation of the worm gear and movement of the movable jaw, the locking disc in the unlocked condition releasing the disc cam surface from engagement with the wall cam surface so that the worm gear is free to rotate.
