Abstract
A box lubricator formed from an extruded U-shape having bolt receiving U-shaped channels for mounting a top cover, and bolt or anchor receiving T-shaped channels along a bottom side for alternatively mounting the box to a horizontal or vertical structure, and having support rails extending on an inside surface of the bottom for holding along their length selectively positioned cam supports within the lubricator box. The lubricator box also provides along its length and arranged on an inside surface, screw receiving C-shaped channels for mounting end covers to the U-shaped housing. By providing the T-shaped rails and the C-shaped rails, the U-shaped housing can be cut to any length and retains its ability for mounting top covers, end covers, and mounting the box to external structure. The lubricator box also provides a segmented cam shaft wherein each segment has a short shaft mounted to a cam lobe, each segment having a polygonal male protrusion and a complimentary polygonal female receiver so that the segments may be stacked to form an elongate and flexible cam shaft arrangement.
