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.

Abstract: A piston-type point of lubrication magnetic flow indicator providing a barrel interfit with a bushing having a cylinder portion penetrating the barrel coaxially and a magnetic piston which reciprocates closely interfit inside the cylinder portion of the bushing. Lube oil enters an inlet port of the bushing, flows through a check valve into the cylinder portion, and impinges on one end of the magnetic piston. The impinging causes the magnetic piston to move in the cylinder portion uncovering at least one port formed through the cylinder portion which opens the cylinder portion to the barrel, directing flow thereto. The lubricating oil flows through the barrel and out of an aperture formed at a forward end of the barrel to a lubrication point. Movement of the magnetic piston through the cylinder portion triggers a magnetic reed switch mounted on an outside circumference of the barrel and generally overlying the relative axial position of the piston in the cylinder portion.

Abstract: A dripless spray nozzle for an intermittent or cyclical spraying operation providing a spray manifold having an inlet port for receiving a pumped material to be sprayed, such as pressurized lube oil, and an inlet port for receiving pressurized air, a mixing chamber for mixing the material and the air, an outlet for conveying the mixture to an attached spray nozzle for spraying an air/material mixture onto an object such as an air/lube oil mixture onto a wheel of a railroad transit car. The spray manifold further comprises a first check valve downstream of the mixing chamber, and a second check valve mounted in the material inlet port. The material to be sprayed is intermittently or cyclically pumped past the second check valve into the mixing chamber. Pressurized air mixes therein with the material and the mixture is sprayed past the first check valve. A reduction in pressure of the pumped material closes the second check valve.
