Babbit

"What is babbit metal? Why, it is an alloy composed of copper, tin and antimony. The quantities of each used vary with the toughness or hardness of the metal desired; and if my memory serves me right, this allow was named after Mr. Babbit, who was the inventor and patentee of a metal composed of the above-named metals."

"The caps for these journal-boxes or bearings may be Babbited by this same jig, and they would, of course, exactly conform to the other portions of the bearings in the frame. […] This drilling jig is a negative of the interior of the frame. It has two sets of bearings, c d and e f, which are at right angles to each other, and which set in the longitudinal and transverse bearings that have been made and "Babbited" in the cast frame, and thus steady and hold it."
