Abstract: An improved switch point machine is provided which can seal out water, even if the machine itself becomes submerged. The operating rod and the point indicating rod that extend out of the switch box housing should be ground round and have a smooth surface for an improved seal. Those rods are preferably chrome plated. Dynamic hydraulic seals can be used to seal out moisture. Internal components, within the switch box housing, should also be sealed to be water resistant in the event water does enter the housing.

Abstract: A clamp comprising a first end including a base and a hooked portion and a second end moveably connected to the base of the first end. The second end includes a clamped portion and a wire jaw maintaining a wire. The wire jaw is shaped so as to be placed in the second end. The wire jaw including a base and arms extending from the base. The arms defining an opening including teeth, the teeth effective to grip and provide high contact pressure on a rail. A spring is disposed on the base of the first end and is effective to bias the second end toward the hooked portion of the first end.

Abstract: A test apparatus is provided for measuring loads applied to an object and for measuring the deformation of the object in response to the loads. The test apparatus includes a stationary work head and a movable arm. The movable arm is selectively movable toward or away from the stationary work head. A load cell has a driven end mounted to the movable arm and a sensing end spaced from the movable arm. A movable work head is mounted to the sensing end and is configured for applying a load to a test object positioned between the stationary and movable work heads. A liner scale also is mounted to the sensing end of the load cell, and a linear encoder or read head is mounted in spaced relationship to the linear scale. The encoder reads deflection in the apparatus in view of loads applied during a test. A controller is provided for moving the movable work head in accordance with test parameters.

Abstract: A self-lubricating bearing assembly for supporting a load on a guide rail which includes a carriage having first and second ends, a guide surface adapter for translation atop the guide rail and an end cap assembly which mounts adjacent one of the ends of the carriage. The end cap assembly includes a seal and a lubricating assembly having a lubricating block made from a lubricant composition and a compression housing for enclosing a periphery of the lubricating block and for biasing the lubricating block against the guide rail to cause the lubricant to contact the rail.
