Model D, Sterling Lubricator

Model D, Sterling Lubricator

The demand for mechanical lubrication of the valves and cylinders of engines and pumps of all descriptions has been rapidly developing within the past few years. The Inter-State Machine Company, of Rochester, N. Y., realizing the demand for a high grade mechanical oiler, has just placed on the market its new Model “D” Sterling Force Feed Lubricator as described herewith. The Model “D” Sterling is of the two-plunger type, one plunger drawing the oil from the lubricator reservoir and pumping it through the large sight feed where the second plunger picks it up and forces it on to the cylinder. The lubricator is operated by some reciprocating part of the engine or pump and is consequently automatic in its operation, feeding the oil faster or slower according to the engine’s speed. This method of lubrication is absolutely positive, as the lubricator automatically starts deeding the oil when the machine on which it is installed is started and stops with the machine. After the engineer has once adjusted the proper feed, the lubricator continues feeding with unfailing regularity which results in perfect lubrication. All the working parts of the Model “D” Sterling Force Feed Lubricator are inside the reservoir working in oil, which not only adds to their life but makes the operation of the ratchet driving mechanism noiselsss. The Inter-State Machine Company makes Sterling Lubricators having feeds running from one to 24 and makes these lubricators for every class of engine or pump.
