Abstract
An in-tie machine for moving the movable elements of a switching device, such as the switch points of a switch point assembly or the moving V-point of a movable point frog, with a sliding device which selectively engages a control rod with either a fixed seat or a moving seat, to shift the movable elements and lock them in place.
Claims22
A machine for railway switching applications, comprising:
- a fixed casing;
- a control rod adapted for sliding movement between two alternative positions relative to said casing, said control rod being connectable to at least one movable switching element of a railway switching application;
- a fixed plate mounted to said casing, said fixed plate having at least one fixed seat;
- and
- at least one operating pin slidably positioned in said control rod, said operating pin being adapted to selectively enter said at least one fixed seat to lock said control rod in either of said two positions relative to said casing.
2 more elements
A machine for selective movement of the movable V-point of a railway moving point frog assembly, comprising:
- a fixed casing adapted to function as a railroad tie beneath the rails of intersecting sections of railroad tracks and the moving point frog assembly between them;
- a control rod mounted within said fixed casing, said control rod being adapted for sliding movement between two alternative positions relative to said fixed casing, said control rod being connectable to a movable V-point of a railway moving point frog assembly located above said fixed casing.
