Patent number: 7104508Abstract: A rail switch is provided having an improved throw rod to enable testing with damaging the switch. The throw rod includes a housing on its length, with a piston and spring located within the housing. A locking pin locks movement of the piston during normal operation, causing the throw rod to act as a solid rod as previously used in the art. The locking pin can be removed during gap testing, to enable a small amount of play in the length of the rod. This eliminates the stress caused on the switch by testing.Type: GrantFiled: April 22, 2004Date of Patent: September 12, 2006Assignee: BNSF Railway CompanyInventor: Loren Delaware

Patent number: 6682024Abstract: 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.Type: GrantFiled: October 5, 2001Date of Patent: January 27, 2004Assignee: Siemens Switzerland Ltd.Inventors: Markus Steinmann, Otto Egli
