Patent 11168791 was granted and assigned to Kurt Manufacturing on November, 2021 by the United States Patent and Trademark Office.
A jaw nut of a vise has a threaded bore with at least one opening on an end face. The jaw nut includes an inner annular groove concentric with a centerline of the threaded bore. The inner annular groove has a radius larger than a radius of the at least one opening from the centerline so as to provide at least a portion of an annular flange about the at least one opening having an inner annular surface facing in a direction opposite the end face. A threaded screw supported for rotation on the vise body threadably engages the threaded bore of the jaw nut. A brush seal is disposed in the inner annular groove with an outwardly facing annular surface engaging the inner annular surface of the inner annular groove.
