Publication number: 20190299345Abstract: A rotary-drive sub-assembly includes a tool, a tool retainer, and a retaining member. The tool includes a fastener-engagement portion, a first threaded portion, and a tool-change-engagement portion between the fastener-engagement portion and the first threaded portion. The tool retainer includes a body. The body includes a symmetry axis, a second threaded portion and a key. The second threaded portion is configured to be threadably fastened with the first threaded portion of the tool so that the tool is rotationally anchored relative to the body of the tool retainer about the symmetry axis and is translationally anchored relative to the body of the tool retainer along the symmetry axis. The key is fixed relative to the second threaded portion. The retaining member is removably coupled to the body at a fixed location.Type: ApplicationFiled: June 19, 2019Publication date: October 3, 2019Inventors: Dennis R. MATHIS, Jason KERESTES, Rachel M.

Patent number: 10377001Abstract: A method of threadably coupling a first fastener with a second fastener using a rotary drive including a tool. The method includes rotationally anchoring the second fastener relative to the tool by co-axially urging a fastener-engagement portion of the tool against the second fastener and rotating the tool relative to the second fastener using a socket of the rotary drive until the fastener-engagement portion of the tool mates with a receiving portion of the second fastener, receiving the first fastener within the socket of the rotary drive co-axially with the fastener-engagement portion of the tool, and rotating the first fastener with the socket of the rotary drive relative to a housing of the rotary drive to cause the first fastener to threadably engage the second fastener.Type: GrantFiled: February 29, 2016Date of Patent: August 13, 2019Assignee: The Boeing CompanyInventors: Dennis R. Mathis, Jason Kerestes, Rachel M. Chow

Patent number: 10245688Abstract: A method of coupling or decoupling a tool of a rotary-drive sub-assembly and a tool retainer of the rotary-drive sub-assembly includes rotationally anchoring the tool to a first tool-change member, rotatably coupled to a base, by engaging a tool-change-engagement portion of the tool with a first tool-engagement portion of the first tool-change member. The method also includes causing relative rotation between the tool and the tool retainer.Type: GrantFiled: February 29, 2016Date of Patent: April 2, 2019Assignee: The Boeing CompanyInventors: Dennis R. Mathis, Jason Kerestes, Rachel M. Chow

Patent number: 10226844Abstract: A method of threadably coupling a first fastener with a second fastener using a rotary drive including a tool. The method includes rotationally anchoring the second fastener relative to the tool. The first fastener is received within a socket of the rotary drive co-axially with a fastener-engagement portion of the tool. The first fastener is rotated with the socket relative to a housing of the rotary drive to cause the first fastener to threadably engage the second fastener. When the first fastener is rotated relative to the housing and while the fastener-engagement portion is mated with a receiving portion of the second fastener, the fastener-engagement portion is co-axially translated relative to a tool-change-engagement portion of the tool and relative to the socket so that a fastener-engagement indicator, coupled with the fastener-engagement portion, extends past a surface of a tool retainer, coupled to the tool-change-engagement portion.Type: GrantFiled: February 29, 2016Date of Patent: March 12, 2019Assignee: The Boeing CompanyInventors: Dennis R. Mathis, Jason Kerestes, Rachel M. Chow
