ABSTRACT:
The automatic rail greasing apparatus in accordance with the invention applies metered quantities of grease-like lubricant to the rails of a railroad track to lubricate the same as the wheels of a train pass therealong. A sensing device senses the number of train wheels passing a location on the track, and in response to the counting of a predetermined number of wheels an electronic controller periodically opens a fluid valve to pass a metered quantity of such lubricant from a pressurized reservoir to a manifolded delivery mechanism for delivering metered quantities of lubricant to a plurality of discrete spaced-apart locations on each rail. The lubricant may be passed directly through an opening in the rail head from the rail web and base side thereof to the top surface thereof on which the train wheels roll. A novel flow restrictor facilitates uniform application of grease to the multiple dispensing locations, and a dispensing reservoir formed in the rail assures dispersion of the grease on the rail head surface while avoiding undesirable back pressure into the dispensing outlets as the train wheels pass thereover.
