  • Patent number: 11358261
    Abstract: 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.

  • Patent number: 11278171
    Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.
