DEFINITION

Classification: 188/38.5

(under subclass 38) Devices wherein a series of detent or stop elements are adjacent the rails arranged in a line parallel to the direction the rails extend and a rail-traversing car or carriage carries thereon an element which is so located that when the car moves along the rails the element will engage one of the stop elements and arrest the car.

(1) Note. The stop elements of this subclass are other than those elements necessary to complete the railway such as crossties, rail connecting plates, rail plates, and the like; the stop elements may be and usually are adjustable in the direction the rails extend.
