Abstract
There is disclosed apparatus for preventing explosive separation of a heavy spring loaded first portion of a parking brake chamber from a second portion thereof. A clamping band, typically secured by a fastener assembly, is provided at the interface between the two portions of the chamber to maintain them in operative engagement. The apparatus disclosed insures continued engagement upon accidental or inadvertent release of the clamping band under spring loading.
Claims9
Apparatus for preventing accidental explosive separation of a first heavy spring loaded section of a spring set safety brake chamber from a second adjacent section of the chamber comprising:
- a. a clamp band circumferentially extending about an interface between the adjacent sections, the band radially outwardly extendable from the interface;
- and
- b. means fixedly attached to the brake chamber adjacent the interface for restrictively engaging the clamp band to limit radial outward extension of the band.
Apparatus for preventing accidental explosive separation of a first heavy spring loaded section of a spring set safety brake chamber from a second adjacent section of the chamber comprising:
- a. a clamp band circumferentially extending about an interface between the adjacent sections, the band radially outwardly extendable from the interface;
- and
- b. means fixedly attached to at least one of the sections adjacent the interface for limiting radial outward extension of the band.
Apparatus for preventing accidental explosive separation of a first heavy spring loaded section of a spring set safety brake chamber from a second adjacent section of the chamber comprising:
- a. a clamp band circumferentially extending about an interface between the adjacent sections and in abutting relationship with the interface, the band radially outwardly extendable from the interface;
- b. means fixedly attached to the brake chamber adjacent the interface for restrictively engaging the clamp band to limit radial outward extension of the band;
- and
- c. means on the clamp band spaced radially inwardly of the means attached to the brake chamber for restrictive engagement therewith upon radial outward extension of the band.
