Abstract
Embodiments of a tool and method for removing sweeper bristles from a railway track broom are disclosed. An exemplary tool may include a tube member for insertion into a sweeper bristle gripped onto a nipple element, wherein two or more slits split a front portion of the tube member into flexible prongs each having outward-facing gripping elements near its tip. A plunger element, located inside the tube member, can be propelled forward into a front end of the tube member to cause the flexible prongs to substantially expand at least part of the front portion of the tube member, thereby loosening the sweeper bristle's grip on the nipple element. A hydraulic assembly coupling the plunger element to a hydraulic pressure source is controlled by a trigger mechanism to supply hydraulic pressure to propel the plunger element.
