Brake system for railway vehicle

Claim 1

In a brake system for a railway vehicle comprising, a brake rod member, a support structure for said brake rod member, said support structure having a horizontally disposed supporting member which is adapted to support said rod member for sliding movements thereon, and an antifriction component made primarily of an ultra high molecular weight polymeric material and carried by one of said members, said component serving to minimize wear and enable antifriction movements during said sliding movements, the improvement in which said component comprises a solid strip portion being a separate elongate strip of substantially rectangular cross-sectional configuration; and said system further comprises self-contained clip means for locking said strip portion against said supporting member, said clip means comprising a pair of resilient parallel legs and a locking projection extending from the outer end portion of each parallel leg toward the other parallel leg, said clip means comprising at least one substantially U-shaped clip having a bight with said pair of parallel legs extending outwardly from said bight, said clip being disposed with its bight against a top surface of said strip and with said parallel legs also embracing opposed vertical surfaces of said strip which are disposed in vertical alignment with said opposed surfaces of said supporting member and being disposed with said parallel legs embracing opposed vertical surfaces of said supporting member and with said projections snap locked beneath a bottom surface thereof; each locking projection having a cam surface and a locking part, each cam surface being adapted to urge its associated leg outwardly from an associated vertical surface during installation of said strip portion against said supporting member and once its locking part clears said bottom surface the associated leg snaps inwardly toward the other leg of said pair with the locking part beneath said bottom surface, each locking projection being defined as an angled end portion adjoining the terminal end of each leg as an integral part thereof, said angled end portion having an outside surface defining its cam surface and a terminal tip defining its locking part; said elongate strip having a cut-out slot therein extending inwardly from a top surface thereof and said U-shaped clip has the bight thereof disposed in nested relation with said slot.
