Since everyone is so smart on their part on vehicles. I figure I'm going to back farther into the past?

Oiler

looking glass suggests oil...

Looks like a steam pressure valve to me to measure your steam pressure.

It's an oil cup. It a screws into the crank arm at the shaft or at the bolsters of a shaft and drips oil. It sorta takes the place of where we would put a zerk fitting to pack grease, but uses oil instead. The thumbscrews at the top are used to adjust the flow to meter out the oil.

When you see old machinist end engineers in pictures with an oil can standing around an old steam, open crank hit or miss, or hit bulb that's what they are doing with the oil cans, they're topping off the oil cups since all those old engines used total loss lube systems.


We use roller and ball bearings these days. So if the bearings aren't in an oil bath we pack them with grease using zerk fittings. Older engines typically used babbitt metal bearing surfaces and so required total loss oil lubrication . So oil cups it was.

I have oiler too
