Abstract: A lubrication system mounted on a railroad locomotive for applying a lubricant to a rail. The system is comprised of a manifold that defines a generally endless, closed lubricant path. A pump is provided to continuously convey a lubricant along the lubricant path. A reservoir for holding the lubricant defines a portion of the lubricant path. A dispensing nozzle is mounted to the locomotive above each rail for directing the lubricant onto each rail. A metering device is associated with each dispensing nozzle. Each metering device is connected to the manifold and an associated nozzle for diverting a metered amount of the lubricant from the lubricant path to the associated nozzle.

Abstract: In accordance with a preferred embodiment of the present invention, there is provided a lubrication system mounted on a railroad locomotive for applying a lubricant to a rail. The system is comprised of a manifold that defines a generally endless, closed lubricant path. A pump is provided to continuously convey a lubricant along the lubricant path. A reservoir for holding the lubricant defines a portion of the lubricant path. A dispensing nozzle is mounted to the locomotive above each rail for directing the lubricant onto each rail. A metering device is associated with each dispensing nozzle. Each metering device is connected to the manifold and an associated nozzle for diverting a metered amount of the lubricant from the lubricant path to the associated nozzle.

Abstract: An automatic lubricator for chain conveyors with a pivoting arm having a roller contacting the chain and moving between the chain side links to place lubricating nozzles along the chain center line. A magnetic proximity sensor on the pivoting arm activates the fluid pump when the nozzles are in position to deliver lubricating fluid to the chain pins. Improved metering pump apparatus diverts fluid from the metering pump to a fluid return line immediately at the end of a lubrication cycle. The metering pump chamber is then primed for the next cycle. Drippage from the lubrication nozzles is eliminated.

Abstract: A lubricating device for delivering multiple clean shots of lubricant to a moving conveyor or the like, comprises an electric motor, a positive displacement lubricant pump having a plurality of individual cylinders and associated pistons driven by a common shaft, a single revolution clutch coupling the output of the motor to the shaft of the lubricant dispenser, and a sensing and control system actuated by the moving conveyor which at an appropriate time causes the clutch to engage the motor to the shaft of the lubricant pump for a single revolution, causing the ejection of a plurality of individual clean shots of lubricant which are directed to selected portions of the conveyor system by individual conduits.

Abstract: A chain lubricating device in which lubricating fluid passes through an inlet line into a shaft to a piston chamber in a pump body where the lubricating fluid is then evacuated to discharge device located on a sprocket to which the pump body is attached, both the pump body and sprocket being adapted to rotate about the fixed shaft. The pump body has a piston and cylinder for receiving and for evacuating lubricating fluid. When the lubricating fluid is evacuated it passes through a passage from the pump body to the sprocket positioned on the shaft. As the sprocket and the pump body rotate about the shaft, the lubricating inlet manifold in the shaft will intermittently align itself with the inlet to the pump body to receive a lubricating fluid, while at the same time the lubricating outlet manifold of the shaft intermittently aligns itself with a passage leading to the sprocket. The lubricating fluid then enters the sprocket and is then discharged from an outlet onto the conveyor system.
