NATIONAL COUPLER RELEASE RIGGING A release rigging which employs a minimum number of partsnecessary to operate the uncoupling mechanism of an M. C. lift coupler is shown in the illustration. This consists of anoperating lever of 1 in. round bar, bent to the shape shown, andtwo malleable iron brackets riveted to the end sill. The sidemovement of the coupler head is allowed by the slip connectionof the lever in the eye of the coupler lock and the draft gearmovement by the slot in the bracket located nearest the coupler,with the outer bracket acting as the center of rotation. When. Section Coupler Release Rigging. ^Coupler this bracket so that an abnormal forward movement of thecDupler, as in the case of the coupler becoming detached from thedraft gear, will result in the lever tending to unlock the couplerand release the adjoining car, preventing the coupler from beingentirely pulled out of the end sill and falling to the track. It will be noted that the lever is simply a 1 in. round steelbar from end to end, bent to fit the particular car to which it isapiilied. In case it becomes distorted in service, the removal ofthe two cotter pins which hold tlie lever in the brackets willallow it to be disconnected from the car. By using the lever onthe opposite end of the car as a pattern, it is an easy matter tobend it back to its original shape without the use of any specialdies. There is a slight offset in the operating lever near the out-side bracket which holds it in the same position laterally at alltimes, thus insuring the desir
