Electro-mechanical locomotive bell ringing apparatus for quick and easy replacement of existing pneumatic bell ringing systems

摘要

An electro-mechanically operated locomotive bell ringing apparatus designed to quickly and easily replace existing air operated bell ringing systems. The bell ringing apparatus is mounted within the bell and the existing bell striker is attached to the apparatus. Closing of a switch mounted on the engineman's console activates a timer which energizes a coil within the apparatus in a predetermined manner to cause the striker to move against the bell.
