Abstract
Wayside lubrication apparatus for railroad track wherein metered charges of lubricant are delivered to points spaced at intervals along the gage sides of the heads of the rails, and systems for and methods of monitoring the apparatus at a location remote from the site thereof.
Claims45
Railroad rail head lubrication apparatus comprising:
- an elongate applicator for attachment to a railroad rail on the inside of the rail extending lengthwise of the rail,
- said applicator having a lubricant flow divider comprising a group of lubricant metering devices,
- each of said metering devices comprising a divider valve operable in response to delivery thereto of lubricant under pressure to deliver a metered charge of lubricant and to become charged for a subsequent delivery of a metered charge,
- the metered charges delivered by said devices being delivered to points spaced at intervals along the length of the applicator with the delivery such as to apply the delivered charges to the inside of the head of the rail to which the applicator is attached.
Apparatus for applying lubricant to the inside of the head of a rail of a railroad track comprising:
- an elongate applicator for said delivery of lubricant,
- said applicator including an elongate mounting bar,
- a lubricant flow divider comprising a group of lubricant metering devices, each metering device comprising a divder valve,
- mounting means at each end of the mounting bar for mounting said applicator in position extending lengthwise of the rail on the inside thereof,
- each said mounting means comprising a first rail flange clamp jaw engaging an inside edge of a flange of the rail and a second rail flange clamp jaw engaging an outside edge of the flange, said jaws being drawn together for the clamping thereof on the flange, and a support for the mounting bar on the first jaw.
Apparatus for applying lubricant to the insides of the heads of the rails of a railroad track, each rail having one or more elongate applicators extending lengthwise on the inside thereof for delivery via passages in said one or more applicators of metered charges of lubricant to points spaced at intervals along the insides of the heads of the rails,
- a lubricant flow divider comprising a group of lubricant metering devices, each metering device comprising a divider valve,
- a container for holding a supply of lubricant alongside the track, and
- a pump for pumping lubricant from the container to said metering devices in response to passage of a train on the track.
Apparatus for applying lubricant to the inside of the heads of the rails of a railroad track comprising:
- at least one lubricant applicator on the inside of each rail for delivery of lubricant to the inside of the heads of the rails;
- a lubricant flow divider comprising a group of lubricant metering devices, each metering device comprising a divider valve;
- a container for holding a supply of lubricant alongside the track;
- a pump for pumping lubricant from the container to the applicator;
- a electric motor for driving the pump;
- said motor being connected in an electrical circuit responsive to passage of a train on the track for operation of the motor to drive the pump.
Apparatus for applying lubricant to the insides of the heads of the rails of adjacent first and second railroad tracks comprising,
- at least one lubricant applicator on the inside of each rail of the two tracks for delivery of lubricant to the insides of the heads of the rails of the tracks,
- a lubricant flow divider comprising a group of lubricant metering devices, each metering device comprising a divider valve,
- a container for holding a supply of lubricant adjacent the tracks, and
- a pump for pumping lubricant from the container to the applicators for the rails of the first track responsive to passage of a train on said first track, for pumping lubricant from the container to the applicators for the rails of the second track responsive to passage of a train on said second track, and for pumping lubricant from the container to the applicators for the rails of both tracks responsive to passage of trains on both tracks.
Apparatus for applying lubricant to the insides of the heads of the rails of adjacent first and second railroad tracks comprising,
- at least one lubricant applicator on the inside of each rail of the two tracks for delivery of lubricant to the insides of the heads of the rails of the tracks,
- a container for holding a supply of lubricant adjacent the tracks,
- a pump for pumping lubricant from the container to the applicators for the rails of the first track responsive to passage of a train on said first track, for pumping lubricant from the container to the applicators for the rails of the second track responsive to passage of a train on said second track, and for pumping lubricant from the container to the applicators for the rails of both tracks responsive to passage of trains on both tracks, and
- a first lubricant line served by the pump for serving the applicators for the rails of the first track and a second lubricant line served by the pump for serving the applicators for the rails of the second track, delivery responsive to passage of trains on both tracks being alternated via said lines.
