Abstract: The invention is an adjustable wrench comprising a handle with a terminal end and grip end, the terminal end defining a lower bolt claw. A jackscrew is slidably coupled to the handle, the jackscrew being movable to control the movement of the upper and central bolt claws. The upper, central, and lower bolt claws are fitted to the shape of a standard hexagonal bolt head, being adjustable to different sized bolts upon terminal or distal movement of the jackscrew relative to the handle. The central bolt claw is fitted through a slot in the upper bolt claw which defines an inclined ramp surface such that movement of one claw is coupled to movement of the other claw. The claws move cooperatively in reaction to the stationary, lower bolt claw to form a tightly fitted surface for a bolt head.

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: An adjustable head wrench with an elongated generally straight offset handle and a stationary jaw fixed to the handle. A movable jaw rides in a bore hole and slot within the stationary jaw with a worm gear. The worm gear in turn fits into a bore hole in the movable jaw and engages internal teeth of the movable jaw with its outer helical gears. At front end of the worm gear threads mount an external adjuster outside of the stationary jaw and wrench head. This rotatable adjuster is used to rotate the worm gear which causes the distance between the object engaging surfaces of the stationary and movable jaws to vary. To retain the adjuster in place and prevent unwanted rotation with respect to the stationary jaw, a biased ball bearing mounted in a cavity of the stationary jaw is used to engage the outer surface of the adjuster.

Abstract: A repair apparatus for tire punctures is operable upon a damaged tubeless tire in situ and includes a hollow probe initially containing a rubber boot disposed in a collapsed condition but subsequently automatically unfolding when urged into the tire interior by a plunger rod in the probe. A stem integral with a circular main body of the rubber boot is connected to the plunger rod by a flexible tether that serves to retain the unfolded boot juxtaposed the puncture point inside the tire while a drive rod forces a measured amount of rubber bonding fluid through the probe to sealingly secure the boot. Alignment and retention of the probe and drive rod is facilitated by a mounting unit secured to the tire by adjustable attachment elements clampingly engaging the rim of the wheel mounting the tire while threads on the probe and drive rod cooperate with tapped bores in the mounting unit to permit controlled advancement and retraction of the probe and drive rod.

Abstract: A toggle joint band wrench for an oil filter; comprises: A pair of side connectors bases which have three functional sets of systems connected between them to combine in functioning as a device. They are: (a) A set of toggle joint mechanisms connected pivotally between the upper parts to support the central toggle joint and its top handle on the top center of the device. (b) A clamping means connected between the middle pans to function for moving the side connectors closer or away from each other. (c) A pair of curved, laminated, toothed, clamping bands connected between the lower parts with a circular opening for an oil filter to be placed in-between them. A handle is connected to the top of the toggle joint pivotally. The clamping means can be adjusted to move the bands closer to each other in clamping and locking onto the oil filter. The toggle joint system keeps the handle constantly centralized. The handle can be flipped to be set on a lateral position in two positions across from each other.

Abstract: An adjustable wrench has a stationary jaw formed at an end of a handle. A slidable jaw is mounted for linear reciprocal movement toward and away from the stationary jaw by a worm gear in mesh with a gear rack on the slidable jaw. An axially movable shaft extends through the worm gear. The worm gear is rotatably mounted on the shaft, and restrained against axial movement relative thereto. An inner end of the shaft is slidably received in a recess in the handle, and a coil spring in the recess outwardly biases the shaft. A lever has a first end pivotally mounted to an outer end of the shaft and an intermediate portion pivotally secured to the handle. The slidable jaw may be moved by rotation of the worm gear to a loosely adjusted position and may be firmly tightened into engagmeent with the head of a fastener by manipulation of the pivotal lever. The wrench allows extremely quick engagement and release with the head portions of various fasteners.
