A trailer tongue jack includes a grease (or zerk) fitting for providing grease to internal parts The jack includes an outer tube and an inner telescoping tube. A threaded insert (or nut) is fixedly attached inside an upper end of the inner telescoping tube. A screw shaft threadedly cooperates with the insert to extend or retract the inner telescoping tube from a lower end of the outer tube. A crank is provided to turn the screw shaft either directly or through gears, and a thrust bearing carries a vertical load between the screw shaft and the outer tube.

A mold for maintaining alignment between mold halves despite a thermal differential between the mold halves. The lock comprises (1) a T-shaped member, consisting of an enlarged, rectangular head and a tongue extending therefrom, and (2) a receptacle with an outwardly opening U-shaped pocket to receive the tongue of the T-shaped member, when the mold halves are pressed together. A vertical conduit is formed in the head and tongue of the T-shaped member, and a horizontal channel, extending through the tongue, intersects the lower end of the conduit. At lest one groove is defined in each side wall of the conduit. A grease fitting is located in a blind hole in the head of the T-shaped member, so that lubricant flows through the vertical conduit, into the horizontal channel, and into the grooves in the opposite side walls of the tongue. The grooves are usually formed in pairs, and are configured in an intersecting X configuration. The midpoint of the X configuration corresponds to one end of the horizontal channel in the receptacle. The grease fitting, vertical conduit, horizontal channel, and grooves in the opposite side walls of the tongue deliver a film of lubricant into the limited clearances between the side walls of the tongue and the interior walls of the pocket to prevent metal-to-metal, line-to-line contact therebetween. In an alternative embodiment, the grooves are located in the parallel side walls of the U-shaped pocket, and are configured in an intersecting X configuration, to deliver the film of lubricant.

A grease gun coupler for delivering grease from a tube of a grease gun to a grease fitting is provided.
