  • Patent number: 11502468
    Abstract: A method of replacing a brush holder includes positioning a handle on the brush holder while the brush holder is connected to a support, rotating the handle relative to the brush holder in a first direction that is clockwise or counter-clockwise to connect the handle to the brush holder, removing the brush holder from the support by pulling the handle with the handle attached to the brush holder, rotating the handle relative to the brush holder in a second direction that is opposite to the first direction while pulling a trigger on the handle that moves a core in the handle upward in a cavity in the handle, and removing the handle from the brush holder.

  • Publication number: 20190181602
    Abstract: An assembly has a handle, a brush holder, and a support that connect and disconnect to each other using a locking mechanism. The handle reversibly connects and disconnects from the brush holder. The locking mechanism includes a connecting member on the brush holder that attaches to the handle by interaction of a locking flange on the connecting member with a pair of teeth inside of the handle. Insertion of the support within the brush holder extends a post on the support through the connecting member to interact with the handle and enable disconnection of the handle from the brush holder when the support is fully engaged by the brush holder. The locking mechanism prevents the handle from releasing from the brush holder before the brush holder is completely seated on the support.
