Apparatus for Interlocking Reverser Handle on a Control Stand of a Railway Locomotive

摘要

Apparatus for interlocking independent control handles for throttle action, dynamic brake action and reverser action, within a control stand for a railway locomotive to permit controlled removal of a reverser control handle in which a first and second cam disks are mounted to a first and second axle for rotation with a throttle handle and a dynamic brake handle such that the disks will interlock with each other so that neither the throttle or dynamic handle can be rotated unless the other is in an "off" position, and having a pivotal lock member secured to the reverser axle, with a member thereon adapted to pivotally lock the reverser lever handle in place when it is secured to the reverser axle. First and second arcuate guide members are provided to engage the pivotal lock member throughout its pivotal rotation with the reverser axle, and includes a member thereon to permit the pivotal lock members to be pivoted to allow removal and insertion of the reverser lever handle when it is in the "neutral" position and the throttle and dynamic brake handles are in the "off" position.
