Abstract
A cable operated piston travel indicator for readily viewing an amount of piston travel of a fluid actuated cylinder assembly positioned in a remote location is provided. The cable operated piston travel indicator of the invention is particularly applicable in the railway vehicle braking industry as an aid in performing pre-departure terminal tests of the air braking equipment of each car of the train. The cable operated piston travel indicator comprises an inner movable cable which is associated and movable with a piston. An outer shielding member encloses this inner movable cable and includes a clear cap with an indicating device thereon for viewing the movement of the inner cable member with respect to the indicating device. The end of the shielding member which includes the indication device thereon may be placed at a readily viewable location so that the amount of piston travel may be easily viewed at any time. The cable operated piston travel indicator of the present invention may be used in any environment wherein it is necessary to monitor the amount of piston travel and may be retrofitted onto currently used systems.
