Patent number: 11358257Abstract: A magnetic clamping device is provided that includes a housing in which a number of magnets are disposed. A magnetizable core extends through the housing between the magnets and is movable with respect to the housing and the magnets. The core can be moved using a suitable mechanism disposed on the housing between an extended position where the core is positioned in contact with the support surface and a retracted position where the core is spaced from the support surface. The position of the core relative to the housing and the support surface adjusts the magnetic holding force transmitted from the magnets through the core to attract and hold the core on the support surface.Type: GrantFiled: June 27, 2019Date of Patent: June 14, 2022Inventor: Kenneth K. Redman

Patent number: 11358259Abstract: A driver tool for insertion and removal of a first part configured for threaded engagement in a corresponding threaded bore in a second part has a driving end portion of polygonal shape with multiple flats configured for engagement in a recess in the first part having a corresponding polygonal shape. Some or all of the flats have a respective grabbing feature or edge designed to grab or grip into the opposing surface of the recess to allow a greater amount of torque to be applied to the first part when the tool is rotated in the unthreading direction than when it is rotated in the opposite threading or insertion direction.Type: GrantFiled: February 24, 2020Date of Patent: June 14, 2022Assignee: ZEST IP HOLDINGS, LLCInventors: James I. Johnson, Evan A. Cook

Patent number: 11358261Abstract: Apparatus for use with a tool assembly in operations of tightening or loosening threaded fasteners about an axis are disclosed, and in one example includes: a lower clamp assembly; an upper clamp assembly; a reaction adaptor assembly; and a spring assembly formed between the upper clamp assembly and the reaction adaptor assembly. Advantageously an operator can tighten or loosen all fasteners without having to change the initial setup of the apparatus. The lower clamp assembly eliminates the need for extra operators and heavy and bulky equipment to hold the apparatus near the fasteners. The upper clamp allows the operator to rotate the apparatus around with ease. The spring assembly stabilizes and eases vertical height adjustment of the apparatus. The reaction adaptor substantially negates reaction turning forces of the tool assembly during the operations. Drive knobs provide easy alignment of and quick and safe mounting of the tool assembly on the fasteners.Type: GrantFiled: August 12, 2019Date of Patent: June 14, 2022Assignee: HYTORC Division UNEX CorporationInventor: Calvin A. Bonas

Patent number: 11358262Abstract: A fastener driving apparatus featuring at least one gas spring and a drive mechanism, comprising a plurality of lifters, for selectively engaging and disengaging said at least one gas spring to energize the gas spring. The lifters the gas spring to energize the gas spring and thereafter release the gas spring, wherein the gas spring releases a portion of its potential energy and accelerates an anvil to engage a fastener. The lifters may engage the gas spring at the same time for a portion of the operational cycle of the apparatus, and the operational cycle may include an intermediate stopping point, which after resumption of a lifter on the gas spring after the stopping point, a relatively small increase of energy in the gas spring thereafter is required to generate a sufficient energy in the gas spring to effectively drive a fastener.Type: GrantFiled: February 21, 2020Date of Patent: June 14, 2022Assignee: TRICORD SOLUTIONS, INC.Inventors: Christopher Pedicini, John Witzigreuter
