It allows the oil to bypass the filter completely if the filter becomes clogged.
The function of lubrication is to deliver clean oil at the correct temperature & pressure to every parts of the engine. To be effective, an engine lubrication System must successfully perform the function of minimizing friction between bearing surfaces of moving parts, dissipating heat & keeping the engine parts clean by removing carbon & other foreign material.
To provide a film of lubrication between metal moving parts.
Because they spin at such high speeds, turbine engines are very sensitive to oil-system contaminants. Even something as small as a piece of grit can cause problems if it gets into the wrong part of the lubrication system. Turbine engines are therefore equipped with very sophisticated and redundant oil filtration systems to ensure the reliability of the engine.
Lubrication and cooling.
Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist.

Small 2-stroke engines don't have any separate lubrication system, so they rely on oil mixed with the fuel to be carried to all the parts of the engine that needs lubrication.
I'm not sure that question really makes much sense. All machinery requires lubrication, and therefore all steam-engine manufacturers designed and included some means to this end in their products.
Blinking is an involuntary reaction, largely controlled by the autonomic nervous system (ANS) and designed as a protection and lubrication function.
"Total loss lubrication" refers to an archaic engine lubrication system wherein oil was added to a tank, passed through the engine, and was either burned or went out on the ground. Used in early racing engines as well as some aircraft, it was obviously long before the days of environmental awareness.
As a "train", there is no typical lubrication system, as it is not necessary. Individual components have grease systems and locomotive components include multiple lubrication systems. So, there is no single invention of a train lubrication system.
