  • Patent number: 8245984
    Abstract: The invention relates to a device for shifting switch rails (6) associated adjustably with stock rails (7) or mobile frog tongues in railroad switches, configured as a latch or vertical clasp closure, comprising locking catches (4) which are activated by means of a cam or slide rod (5a, 5b), and closure pieces (3) and tongue attachments (2), wherein each locking catch (4) is pivotably supported in a tongue attachment (2) and the switch rail (6) is connected detachably to the tongue attachment (2). An improved and simpler adjustment option is to be created for such a device. For this, the cam or slide rod (5a, 5b) is vertically height-adjustable via a multi-edge body (9) mounted detachably in both closure pieces (3).

  • Patent number: 6270041
    Abstract: An apparatus for mechanically locking the end positions of movable point sections, with two adjusting rods (12, 14 ), each of which is connected with one of the point sections and which are coupled mechanically with one another, with at least one locking tappet (28) for locking the adjusting rods in each case in one of their end positions and a force limiting device, which cancels the locking, when the force, exerted by the point sections on the adjusting rods, exceeds a certain value, and the force limiting device is formed by a coupling device (30, 32), which yields when stressed and is located between the adjusting rods (12, 14), and by a transfer mechanism (16, 38), which converts the movement of one of the adjusting rods into a movement for unlocking the locking tappet (28).
