A while back I picked up a North Bros. (Yankee) breast drill No. 1555 with a three jaw chuck for straight shank bits. This is a neat drill with two crank speeds selected by a lever and a five position racheting mechanism selected by a slider similar to a Yankee screwdriver. The five positions are:
Plain – turn the crank in either direction to turn the spindle to that direction
Left hand ratchet - the crank rachets in one direction to turn the spindle left
Right hand ratchet - the crank rachets in one direction to turn the spindle right
Double right rachet– the crank rachets in both directions to turn the spindle to the right
Lock – locks the crank and spindle
It appears the drill was designed for use in tight spaces. The rachet mechanism was patented in 1908. My internet research shows a lot of info on North Bros and Stanley’s acquisition of Yankee but almost no information specifically about the 1555. Do any of yall have information about what its’ intended use was?
