Hey all. I got these from an old house we are cleaning out today. I was told they were old cranks for an old vehicle...Any ideas on the exact use of these and age prhaps? thanks!!
Lost Hunter nailed it. One of my many part time jobs in college was helping remove old coal fired furnaces and replace with modern forced air gas furnaces. The heavy iron in those old furnaces was impressive. I recognize the cranks. Put many of them in the scrap sale truck.
An engine crank usually had two notches at an angle on the working end. Acted as a safety clutch to keep you from spinning around when the engine started. Hopefully ... <<lol>>. Also engine cranks were never a square thing on the end.
