Because It's Friday

A longish piece on the work of a fireman in this century.

A number of the ports for oiling seem to be capped with nothing more than corks.

The "corks" (wooden plugs, probably) are just there to keep the dirt out... used to be, they were lead tapered plugs, or sometimes brass.

The oil hole leads to a chamber filled with yarn or string or (sometimes) oakum, which then keeps a thin film of oil on the bearing surfaces, but keeps it from just running out the clearances on the sides. It acts as a wick.

Larger ones had cast iron caps, sometimes with a spring retainer, but the same fiber filling for the same reason. The oil they use is about 70 weight or even heavier, often with a large amount of sulfur in it.
