20080289454 | Wrench - A wrench capable of engaging a workpiece from the side or top. When the workpiece is engaged on the side, a movable jaw opens when a slight pressure is applied against a flat or a point of the nut or bolt. After the jaws of the wrench have pushed past the workpiece, a pin and spring mechanically return the moveable jaw to its closed position. In its closed position, the workpiece is retained by the jaws in the proper seat position. When tightening or loosening the workpiece, the direction of the pull is towards the fixed jaw. Disengagement between pulls is accomplished by turning in the opposite direction of pull. The wrench rides over the points of the workpiece and automatically reseats itself. | 11-27-2008 |
20120234140 | VALVE WRENCHES - In one embodiment, a valve wrench for rotating a knob may include a handle and a jaw assembly coupled to the handle. The jaw assembly may include a fulcrum member, a hook member and a bias member. The hook member may be pivotably coupled to the fulcrum member and may be aligned to the fulcrum member at a pivot angle. The fulcrum member and the hook member can form an opening there between to accept the knob. The bias member may be disposed between the fulcrum member and the hook member to bias the hook member towards the fulcrum member when the jaw assembly is engaged with the knob. | 09-20-2012 |
20150128769 | SPANNER WRENCH - An adjustable spanner wrench which maintains a predetermined engagement position. The spanner wrench has a rotatable engagement arm attached to a body, wherein the engagement arm is discouraged from rotating in an opening direction unless released. The spanner wrench has a body, an engagement arm, and a release mechanism which allows or prevents rotation of the engagement arm respective to the body in the opening direction. | 05-14-2015 |
20150360350 | Multi-purpose ratchet piper pliers - A piece of multi-purpose ratchet pipe plier comprise a handle, an upper jaw clamp, a pin shaft, a torsion spring, an arc-shaped tooth surface insert block and an upper tooth surface inert block, wherein the upper jaw clam is hinged on the handle through the pin shaft, the torsion spring is arranged in the assembly slot of the handle and connect with upper jaw clam and the bottom of assembly slot in the ends, the arc-shaped tooth surface insert block is fixed on the handle by tenon, and the upper tooth surface insert block is fixed on the upper jaw clamp by tenon. The anti-skip teeth on the handle and the upper jaw clamp are disassembled and replaced, the whole plier opening can clamp the pipe through the tooth surfaces at three different directions for realizing anti-skip function. | 12-17-2015 |
081100000 | Traveling jaw | 4 |
20090133540 | PLIERS HAVING GREATER HOLDING FORCE - A pair of pliers include a shank, a fixed jaw locked onto the shank, and a movable jaw pivotally mounted on the shank and movable relative to the fixed jaw. Thus, the first contact point of the locking teeth of the fixed jaw and the second contact point of the first engaging teeth of the first toothed face of the movable jaw have a larger friction with a workpiece by a special angle design of the fixed jaw and the movable jaw to enhance the clamping force of the fixed jaw and the movable jaw on the workpiece, so that the workpiece is clamped by the fixed jaw and the movable jaw exactly and closely to prevent the workpiece from being slipped from the fixed jaw and the movable jaw during operation of the pliers. | 05-28-2009 |
20100242686 | REPLACEABLE WRENCH JAWS - A tool for gripping and manipulating components such as pipes and nuts; the tool having gripping surfaces provided on removable inserts in the head and jaw such that the gripping surfaces can be replaced if worn, or interchanged, according to need. In particular the invention provides a self-adjusting wrench and a plurality of replaceable or interchangeable gripping inserts for use with the wrench. | 09-30-2010 |
20100294085 | Adjustable pliers - A adjustable pliers comprises a body used to operate the movable pliers including a fixed jaw extending outward therefrom and having a holder mounted on a top end thereof, including an arcuate recess fixed on a middle portion of a front side thereof; a movable jaw pivoted in the holder, serving as engaging a workpiece, and including a guiding rib relative to the arcuate recess extending from a bottom end thereof to be adjusted and moved along the arcuate recess; a locking mechanism pivoted in the cavity of the body and including a control unit to operate the locking mechanism and to drive a pushing member, the control unit including locking and unlocking positions so as to move across the notch of the arcuate recess and then to bias against the guiding rib, thereafter, the pushing member is driven to move downward, thus disengaging the guiding rib to slide freely. | 11-25-2010 |
20140116206 | BASIN WRENCH - A basin wrench is described having a telescoping assembly, pivotal jaws, a light, and a removable T-bar assembly. The wrench includes a polymeric housing having a contoured gripping region. The T-bar assembly includes a pivotally mounted hub and bar slidably retained within the hub. The T-bar assembly can be placed in a stowed position in which the bar is positioned alongside the housing. The wrench also includes magnetic retaining provisions to retain the T-bar assembly in its stowed position. | 05-01-2014 |
081106000 | Traveling fulcrum | 1 |
081109000 | Slotted guide | 1 |
20090308209 | FLEXIBLE THREADING SYSTEM - A wrench has a socket defined by a plurality of flat faces and a handle. A first threading tool is provided having a shape and dimension to fit into the socket. An adapter that retains a second threading tool includes a connector having the same shape and the dimension as the first threading tool that fits into the socket. A retaining member is rotatably mounted to the body for movement between a first position and a second position for locking the adapter and the die in the socket. The retaining member has a second plurality of flat faces defining an opening where the second plurality of faces are coextensive with the faces of the socket when the retaining member is in the first position and are offset from the faces of the socket when the retaining member is in the second position. | 12-17-2009 |
