Patent number: 4872654Abstract: A work-holding implement for use in honing or otherwise machining the inner surface of a bore in a workpiece comprises a torsion-carrying spring band coil mounted at one end of a handle. Most of the inwardly exposed surface of the innermost turn of the coil is a gripping surface, while the remaining turns in the coil have smooth bearing surfaces. A workpiece is gripped by the innermost turn, and as an interior bore in the workpiece is being honed or otherwise machined, rotational torques exerted on the workpiece by the machine tool cause the coil to become more tightly wound around the workpiece. As the workpiece is being worked on, the tightened coil bears against a planar segment of the spring band forming part of the implement and deforms it into a curved surface conforming to the workpiece surface over which contact is made.Type: GrantFiled: February 18, 1988Date of Patent: October 10, 1989Inventor: Harold A. Seele

Patent number: 4866813Abstract: A load carrying handle for securement to an article to be hand-supported or displaced. The carrying handle comprises a handle grip having a strap retaining elongated cavity therein. The cavity has an open end and a bottom end wall. An article attaching element having at least a flat grip attaching portion is also provided. A wedge rod is disposed in tight fit in the cavity with the attaching portion of the attaching element wedged between the wedge rod and extends over opposed sides of the wedge rod and an inner end thereof. The wedge rod is dimensioned so that an outer end thereof terminates substantially flush with a peripheral end wall of the handle grip about the open end so that when the carrying handle is secured to an article and the attaching element is secured tightly about the article, the wedge rod outer end will abut the object and provide a solid connection therewith with the attaching portion held secured between the handle grip and wedge.Type: GrantFiled: December 28, 1988Date of Patent: September 19, 1989Inventor: Andre Dupont

Patent number: 4848192Abstract: A strap-type wrench for use in removing rotatable closures is disclosed which has two rings to assist in removing the slack in the gripping strap, and a pressure plate with a frictional gripping surface positioned on the wrench to allow the frictional gripping surface to be forced radially inwardly against the object being gripped by the wrench, thereby enhancing the frictional grip of the frictional gripping surface on the object. The rings may be sequentially pulled to first tighten the gripping strap by pulling the first ring and then to pull the slack portion of the gripping strap gathered by the first ring with the second ring in a path which will resist loosening due to frictional restraint of a portion of the gripping strap located between the wrench handle and itself.Type: GrantFiled: August 15, 1988Date of Patent: July 18, 1989Inventor: Keith Jeffreys

Patent number: 4840093Abstract: A device for loosening and tightening the lids on jars or containers. The device has a handle, and a strap and brace attached to the handle. The strap is placed through the brace and formed into a loop so that it may be slipped over the lid. When a rotational force is applied to the handle, the brace pulls against the strap so as to apply a rotational force to the lid which is greater than the force applied to the handle. A spike extends from the top of the device which is placed through a hole in the strap to secure the strap to the handle. The strap has a series of holes to accommodate a large variation in sizes of lids. For loosening the lid, a counter-clockwise force, relative to the center of the lid when viewed from above, is applied to the handle. For tightening the lid, the handle is reversed and a clockwise force is applied to the handle.Type: GrantFiled: December 16, 1987Date of Patent: June 20, 1989Inventor: Leman Goldman, Jr.

-
Patent number: 4646593Abstract: This invention provides an improved and simplified tool for rotating a cylindrical object as conventionally accomplished by a pair of pliers or a pipe wrench, but protecting the circumference of the object from damage. A standard length of rod having a polygonal cross section the sides of which intersect at sharply defined fulcrum points, generally square or hexagonal, from a conventional socket wrench set will make it perform the additional function as a multipurpose tool simply by extending an axial slit inwardly from one end to receive thereinto a flexible strap forming a loop about the cylindrical object. The polygonal shape provides fulcrum corners gripping the strap as it is wrapped about the rod to tightly grip and rotate the cylindrical object and thus prevent circumferential slip which together with elasticity in the strap significantly reduces the leverage necessary to rotate the cylindrical objects with small diameter rods.Type: GrantFiled: January 16, 1986Date of Patent: March 3, 1987Assignee: Plastic Oddities, Inc.Inventor: Charles D. Robertson

Patent number: 4552040Abstract: An improved wrench includes a rigid band extending between a pair of spaced-apart end plates which are supported directly upon a common threaded shaft. In a preferred form of the invention, the band has a plurality of sequential and incremental flat surfaces extending along one edge between the end plates, and a file-like inner gripping surface strengthened by a V-shaped ridge forming the remainder of the band. As the shaft is rotated by hand about its longitudinal axis, one end plate remains generally stationary with respect to the shaft while the other end plate moves along the shaft either toward or away from the stationary end plate, depending on the direction of shaft rotation. When placed about a portion of an article such as an oil filter or the like, movement of the end plates toward one another causes the inner surfaces of the band to substantially uniformly grip the article about its circumference.Type: GrantFiled: October 22, 1984Date of Patent: November 12, 1985Inventor: Hyo J. Bang

Patent number: 4478113Abstract: A device is disclosed herein for aiding in properly connecting the threaded segment of one object, for example a spark plug, to a complementary threaded segment of a second object, for example an engine block including a complementary threaded hole. This device is designed so as to be capable of applying sufficient torque to the first object to loosely connect its threaded segment to the threaded segment of the second object in a properly threaded fashion. On the other hand, the device is designed so as not to be able to apply sufficient torque to the first object to connect together the threaded segments in a way which would strip or otherwise damage the threads. In this way, once the two objects are loosely connected together in a properly threaded fashion, a second device, for example a standard socket wrench, can be utilized for tightening the two objects without fear of damaging their threads.Type: GrantFiled: May 3, 1982Date of Patent: October 23, 1984Inventor: Herwig M.

Patent number: 4145938Abstract: A strap wrench has a handle having a strap element pivoted to the handle by a pair of links to permit passage of the free end of the strap portion between the links, whereby the strap may be wrapped in full circumscribing relation to a workpiece. The handle has a camming surface positioned to confront the exposed surface of the strap when it is wrapped around the workpiece and to engage the same and without moving parts to anchor the strap at that point when said handle is actuated to apply torque to the workpiece. The strap has a friction surface on the interior side confronting the workpiece and has a guide surface on the exposed side with lesser friction to permit the strap to slide over said camming surface prior to applying torquing action upon said handle to afford snug engagement of the strap with the workpiece. Preferably, the handle is formed of a one-piece rigid plastic composition having a density which permits the wrench to float near the surface of a body of liquid.Type: GrantFiled: October 11, 1977Date of Patent: March 27, 1979Inventor: Jonathan L.
