SPRING-STYLE AIR BRAKE HOSE SUPPORT

摘要

A spring-style railway hose support has a retraction-biased extension unit of a longitudinally compressible spring and a pair of oppositely directed internal wireforms within the longitudinally compressible spring. The internal wireforms engage respective ends of the longitudinally compressible spring, and a closed end of each is configured to allow it to project beyond a respective end of the longitudinally compressible spring. The retraction-biased extension unit is adapted to be directly or indirectly connected to a railway brake hose and to a railway car component that is positioned above the hose on a railway car.

主权项

1. A railway hose support, comprising:
a longitudinally compressible spring having a first end, a second end, and an inside surface; a first internal wireform positioned at least partially within the longitudinally compressible spring inside surface and having at least two legs meeting at a closed end, each leg having a free end spaced away from the closed end, each free end securely engaging the longitudinally compressible spring first end; a second internal wireform positioned at least partially within the longitudinally compressible spring inside surface having at least two legs meeting at a closed end, each leg having a free end spaced away from the closed end, each free end securely engaging the longitudinally compressible spring second end; and the closed end of each of the first and second internal wireforms is accessible, whereby movement of the respective closed ends in opposite directions compresses the longitudinally compressible spring when a load is applied between a railway hose and a railway coupler, the combination of longitudinally compressible spring and internal wireforms being a retraction-biased extension unit.
