- Noting a lubricator in which the feeding of the lubricant is visible through a tube of glass, uniformity of feeding being thus assured.
Sorry, no etymologies found.
The lubrication is effected by means of a triple sight-feed lubricator, one feeder delivering to steam inlet, and two serving the main shaft bearings.

We had an Armington & Sims engine with sight-feed oiler.
