ABSTRACT:
An improved sweeper bristle element is disclosed especially adapted for use on a railway roadbed or track cleaner using a rotating drum onto which a plurality of bristles are fixedly supported. Each bristle element preferably includes an elastomeric stem of 80 durometer hardness with a toe of 60 durometer hardness wrapped around the end and one side of the stem. Rotation of the drum imparts centrifugal force on the bristles causing loose material contacting the toes thereof to be driven away. The stem and toe may be reinforced by fabric and/or spring steel and preferably are laminated together in a vulcanization process. The bristles are formed in a paddle-like configuration which increases the structural strength thereof and makes them simple to install on the drum. If desired, the bristle toe portion may be slitted to render the bristle adaptable to tight situations while maintaining the structural advantages of the paddle-like configuration.
