Abstract: A device for locking end positions of switch parts, having two parts, relatively axially displaceable and positively coupled in at least one direction, including a tube and a rod guided within the tube, at least partially arranged in an outer tube. Locking members cooperate with the parts and outer tube and are displaceable into a locking position in the outer tube's recess. Locking members include ring segments chamfered on insides forming first abutment surfaces converging obliquely toward rod axis. First abutment surfaces cooperate with oblique counter abutment surfaces in a rod recess for holding the rod and the tube coupled during the rod's first displacement path and for urging segments outwardly to emerge from rod recess, and to slide onto the rod's outer surface adjacent rod recess and to immerse into locking position in the outer tube's recess upon rod movement relative to the tube over a second displacement path.

Abstract: A switching assembly includes a pair of hollow ties, a pair of supports, and a linkage. The linkage extends generally through the hollow ties, whereby the cribs are generally free of linkage components, and the ballast in the cribs can be compacted with known automated machinery. The linkage includes a number of lugs and a number of rods, with the rods each being formed from standard bar stock and threaded, and with the linkage configuration avoiding the need to custom bend any of the rods. The hollow ties are formed from generally available standard box section steel, as are the supports. The spacing between the hollow ties can be varied in accordance with the pitch of the other rail ties of the railroad switch. Each hollow tie can include a heater. The switching assembly is highly adjustable, which makes it suitable for use in numerous different track configurations.

Abstract: The invention relates to a device for locking the end positions of movable switch parts and, in particular, the movable point (1) of a frog, in which two relatively axially displaceable parts are capable of being displaced into a position coupled with each other in a positive manner in at least one direction of movement, wherein the relatively displaceable parts are comprised of a tube (5) and a rod (6) guided within the tube (5) and are at least partially arranged in a stationary outer tube (4), whereby locking members (8) cooperate with the relatively axially displaceable parts (5, 6) as well as the outer tube (4) and are capable of being displaced in the radial direction into a locking position in a recess or inner annular groove (15, 16) of the outer tube (4). Said device is designed such that the outer tube (4) is comprised of two tube parts (17, 18) capable of being axially displaced within each other, and that each tube part carries at least one recess or inner annular groove (15, 16).

Abstract: Railway switches are subjected to a high degree of stress due to the influences of weather and as a result of trains traveling over them. This may result in changes in adjustments and settings made at the time of mounting. In order to permit, in particular in the case of hollow sleepers, simple re-adjustment of a drive rod relative to the cam rods, an attachment element can be connected to an attachment flange by a positive lock, formed by various adjustment keys and a main key, and using locking screws in such a way that fine adjustment by appropriately selecting the arrangement of the adjustment keys is possible. Coarse adjustment is made by an asymmetric arrangement of the bore holes for connecting to a drive rod as well as by selecting one of the two bore holes.
