Abstract
A manually releasable, spring-applied, air-released parking brake device has a hollow guide rod and a non-rotatable spindle connectable to the brake rigging extending through a portion of a cylindrical housing. On one end of the guide rod is secured a portion of a clutch arrangement, and on the opposite end is secured a spline member having a plurality of externally disposed spline grooves. A latching member having an extending surface engages the spline grooves of the spline member, thus preventing rotational movement of the spline member, guide rod, and clutch portion. A release lever, connected to the latching member, allows for engaging and disengaging the latching member and spline member. When the latching member has been disengaged from the spline member, as corresponds to a manual release of the parking brake device, a retractable blocking member is urged against the end surface of the spline member. The blocking member prevents engagement of the latching member and spline member, thus no longer preventing rotational movement of the spline member.
