Benefits of technology

[0005]In one aspect of the invention, an applicator assembly for delivery of a pumpable material to a top surface of a rail head of rail generally comprises an applicator body having at least one orifice for delivery of the pumpable material to the top surface of the rail. The body is resiliently yieldable to permit the applicator body to move from a raised position, in which the orifice is positioned for delivering the pumpable material to the top surface of the rail head, to a depressed position in the event the applicator is contacted by a train wheel. The applicator body thereafter is adapted to return to the raised position.

Problems solved by technology

However, such prior art devices have been less than satisfactory for any number of reasons.

Embodiment Construction

[0021]Referring to FIG. 1, a conventional railroad track, generally indicated at 10, is shown as comprising a series of rail ties 12 and a pair of parallel rails, each generally indicated at 14. Train wheels 16 rolling on the rails 14 are also shown. A system of this invention for applying a pumpable material to a rail head 18 of each rail 14 is indicated generally at 20. The system is particularly adapted for applying a friction modifying material to the rail head 18, and even more particularly adapted for applying a material that controls the friction between the rail 14 and the wheels 16 of a train. A suitable pump 22 delivers the pumpable material under pressure from a reservoir 24 through a main conduit 26 to the inlet 27 of a divider or distribution valve 28. For example, the pump may be a 24 VDC electric Flowmaster® pump, and the distribution valve may be a SSV Metering Device with cycle switch, both of which are manufactured and sold by Lincoln Industrial Corp., St. Louis, M...

Abstract

An applicator assembly for delivery of a pumpable material to a top surface of a rail head of rail includes an applicator body having an orifice for delivery of the pumpable material to the top surface of the rail. The body is resiliently yieldable to permit the applicator body to move from a raised position, in which the orifice is positioned for delivering the pumpable material to the top surface of the rail head, to a depressed position in the event the applicator is contacted by a train wheel. The applicator body thereafter is adapted to return to the raised position.

Description

FIELD OF THE INVENTION[0001]This invention relates to an apparatus for applying pumpable material to a rail head of a rail, and more particularly to an apparatus for applying a friction modifying material to a rail head of a railroad rail.BACKGROUND OF THE INVENTION[0002]It is common practice to apply lubricants (e.g., grease) and other friction modifying materials onto railroad rails, such as to the tops or sides of the rails at or near curves, turnouts, switches and other locations where such materials are needed or desired. As applied to the rails, such materials either reduce or increase the friction where necessary to improve train performance and reduce wear on both the rails and the train wheels.[0003]In the case of a friction modifying material that controls the friction between the train wheel and the rail, the conventional practice is to apply the material to the top of the rail to contact the train wheels. However, such prior art devices have been less than satisfactory f...
