摘要： Chain tension sensing device includes a hollow enclosure, a sensor mounted in a stationary position within enclosure and a member mounted for a reciprocal movement in a substantially linear direction relative to the sensor. The member includes a chain engaging first portion, a second portion mounted for reciprocal movement and a sensor target disposed on a distal end of the second portion. A compressible resilient member is mounted in abutting engagement with at least a rear surface of the first portion. Chain take-up attains tension thereon generating force and moving the member towards the sensor so as to position the sensor target in operative sensing alignment therewith. Chain let-up causes the compressible resilient member to move the member in an opposite direction, removing the sensor target from the operative sensing alignment with the sensor.

摘要： A parking brake assembly for a railway car includes a ratchet mounted for rotation on a threaded piston rod of a brake actuator and a holding pawl engageable with the ratchet for maintaining a push rod of the parking brake assembly to apply braking force when the air pressure is lost in the brake pipe and releasing the push rod to accordingly release the braking force when the supply of air pressure in the brake pipe is restored. An operating lever and a cylinder connected thereto are provided for selectively rotating the holding pawl. Valve is provided for supplying air pressure to and evacuating it from the cylinder. Release mechanism is provided for manually releasing the braking force. The parking brake assembly is employed with either truck-mounted or carbody-mounted braking system.

摘要： A constant contact side bearing assembly for a railcar includes a housing having a base, a pair of mounting apertures formed through a thickness of the base, a generally cylindrical housing wall upstanding on the base, a pair of diametrically opposed channels, a pair of diametrically opposed openings and a guide member disposed centrally on and upstanding from an inner surface of the base. A cap is disposed for reciprocal axial movement relative to the housing. An elastomeric spring is disposed within a generally closed chamber formed by a combination of the housing and the cap. A pair of air passages is provided for dissipating heat generated during operation of the constant contact side bearing assembly. Each air passage is defined by a pair of aligned openings formed through a wall portion of the cap. Each opening may be disposed within a pocket provided within the cap wall.
