ABSTRACT:
The present invention relates to a semi-rigid sweeper cover for use in mechanical street sweepers and, in particular, to a polymeric cover for rotary sweepers. The semi-rigid sweeper cover is effective to inter-act with and assist a sweeper brush in lifting and guiding swept materials to a storage area. The sweeper cover has an inner surface which conforms to the shape of the sweeper brush when in motion and is comprised of a polymer selected from the group consisting of rubber, ultra-high molecular weight polyethylene, polypropylene, polyurethane, nylon and acrylic with embedded fibers. The use of such polymers greatly extends the useful life of the sweeper cover. The polymeric cover described by the present invention may be used as an inner protective liner for an exterior metal cover. Alternatively, the polymeric cover of this invention may be used, by itself, as a sweeper cover. Metal tubing and stud bolts are attached to the exterior of the cover so as to permit it to interact with and connect to a mechanical street sweeper in the same manner as present sweeper covers operate.
