Patent number: 10814442Abstract: A nut torqueing device for a recessed nut is disclosed. The nut torqueing device includes a nut engaging assembly to engage a nut in a recess. The nut engaging assembly includes: a nut engaging element to engage the nut in the recess, at least one stackable riser element to stackably connect to one of the nut engaging element and an adjacent stackable riser element therebelow, and a transmission engaging element to stackably connect to an uppermost one of the at least one stackable riser element. A ratchet interface within the nut engaging assembly allows rotation of the nut engaging element in only one direction, while other stackable elements rotationally interlock. A low profile transmission extends within a small space to transmit rotational power to the nut engaging assembly. The nut torqueing device is applicable with a terminal nut of an electric generator.Type: GrantFiled: October 3, 2016Date of Patent: October 27, 2020Assignee: General Electric CompanyInventors: Donald Alden VanSlyke, Murat Alver, Erkin Bayindir, Philip Frank Burnett, Curtis Maurice Hebert, Mesut Merev, August Elwood Pendergast, Paul August Quail

Patent number: 10284056Abstract: A brush holder apparatus has a stationary support member having two opposing grooves, a fork electrical connector, and a conductive bar passing through a main body of the stationary support member. A brush holder is releasably affixed to the stationary support member, and has two rails that slide along the grooves. The brush holder's knife electrical connector mates with the fork electrical connector. A brush spring is clipped on the brush holder, and presses a brush against a collector. A brush lead connects the brush to a brush terminal. The brush terminal has a generally L-shaped body with a lower part thereof retained under a terminal compression plate, and an upper part thereof located on a front side of the terminal compression plate. The brush terminal is removed from or installed into a front side of the brush holder, and by hand or without the use of any tools.Type: GrantFiled: April 13, 2017Date of Patent: May 7, 2019Assignee: General Electric CompanyInventors: Frank Austin Scalzo, III, Albert Eugene Steinbach, Paul August Quail, Eric Steven Buskirk, Benjamin Alber Mancuso, Curtis Maurice Hebert, Matthew Thomas Preston

Patent number: 10224776Abstract: A retention assembly for retaining a plurality of elements in a stator slot of an electric machine is provided. The retention assembly may include a stator wedge fixedly positioned in a dovetail in the stator slot to retain the plurality of elements; a top ripple spring between the plurality of elements and the stator wedge; and at least one shim positioned between the stator wedge and a load bearing surface of the dovetail. A method may include compressing the stator wedge in the stator slot from a first position thereof relative to the dovetail of the stator slot, the compressing creating a gap between the stator wedge and the dovetail. A shim may be inserted in the gap; the compressing released such that the shim retains the stator wedge in a second position that is more compressed relative to the plurality of elements in the stator slot compared to the first position.Type: GrantFiled: June 3, 2015Date of Patent: March 5, 2019Assignee: General Electric CompanyInventors: Eric Steven Buskirk, Andrew Duane Brown, James Jonathan Grant, Curtis Maurice Hebert, Benjamin Alber Mancuso, Matthew Robert Martin, Jessica Mary Powers
