Rail lubrication apparatus

A clamp in combination with a pump actuator, said clamp for use in maintaining the pump actuator in position with respect to various sized rails of the type having a base with outwardly extending flange and a web, said clamp comprising;

• a rigid base section having first and second oppositely positioned ends;
• a rigid hook extending from said first end of said base section and sized to receive any one of the plurality of variously sized rail base flanges;
• a hold-down screw;
• and
• a rigid projection extending substantially vertically upwardly from said second end of said base section, said rigid projection being displaced along said base section a sufficient distance from said hook to enable said hook to be slide under a rail and to engage the rail base flange on the side of the rail opposite of the side on which said projection is positioned, said projection having a threaded bore therethrough for receiving said hold-down screw, said bore and said projection cooperating to orient said hold-down screw at an angle with respect to said base section whereby said hold-down screw extends downwardly toward the web such that said screw is oriented to contact the pump actuator and develop a force for holding the pump actuator in position with respect to the rail and a counterforce is developed for holding said hook in contact with the rail base flange and a moment is developed for holding said base section in contact with the underside of the of the rail,
• said projection, base section, and hook being integrally formed;
• said pump actuator having;
• a first pair of brackets, each of said brackets of said first pair of brackets having an angled surface acting as a bearing surface for said hold-down screw;
• a plurality of threaded holes extending horizontally through said pump actuator and a plurality of threaded adjustment screws, one screw positioned within each of said threaded holes;
• a second pair of brackets having a horizontal portion and a vertical portion, each of said second pair of said brackets being connected along its vertical portion of said pump actuator, said horizontal portion of each of said second pair of said brackets having a threaded aperture therethrough for receiving an elevation screw;
• a pair of elevation screws, one positioned within each of the threaded apertures, said screws being of sufficient length to facilitate contact with the rail base flange when a vertical face of said pump actuator is engaging a side of a head of the rail, whereby upon engagement of said hold-down screws with said angled surfaces, said pump actuator is held in position against the rail.
