   • 1886 July 15, The Wood-worker, volume 5, number 5:

     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.

   • 1890, Dickerman's United States Treasury Counterfeit Detector, A Notorious Counterfeiter, page 19:

     The materials used in the manufacture of the coin were silver and babbit metal.

   • 1892, Alexander Ritchie Leask, Triple and Quadruple Expansion Engines, and Boilers and Their Management:

     To pack the box, first insert next to the ring I a ring of round asbestos packing, then the smallest set of babbit metal rings; then insert alternately two coils of asbestos and the next smallest babbit ring, and so on, as shown on drawing, until the box is full, taking care to place the asbestos H and the metal rings G so that the joint spaces between the ends do not come together.

   • 1913, “Testing of Bearing Metals”, in Journal of the Institute of Metals, volume 10:

     The original "babbit metal" for lining bearings is a "tin-base" alloy containing about 90 per cent. tin, the remainder being copper and antimony.

   • 1917, “Letters from Marine Engineers”, in International Marine Engineering, volume 22, page 319:

     After removing the cap and wiping the journal dry, a set of leads is taken (for babbit bearings, soft lead wire should always be used. Never use fuse wire, as it will cut into the babbit rather than compress, as it is very hard.)

   • 1918 March 1, “Points on Babbiting”, in Power Plant Engineering, volume 22, page 213:

     In plants where the engineer has charge of the shafting, pulleys and belts, the bearings will sometimes get hot, and if this continues too long the babbit may melt.

   • 1930, Western Machinery and Steel World, volume 21, page 373:

     However, this impression is misleading, for to produce reliable and dependable babbitted bearings the workman must be trained, the babbit metal carefully selected, temperatures kept within well defined limits, and the tinning process and handling of the shells, mandrels and metals during the heating and pouring process must be given careful study and consideration.

   • 2012, David F. Tver, Encyclopedic Dictionary of Industrial Technology:

     True babbits are tin-base alloys strengthened by the presence of antimony and copper, and occasionally containing lead.
