Following the 1875 dissolution of Millspaugh, Rowley & Millspaugh, Thomas Millspaugh and John H. Millspaugh started a business manufacturing and repairing engines and saw mills: Millspaugh Brothers. They were joined in 1882 by Fred H. Sweet (who had been working at Rowley & Hermance), and Williamsport Machine Co. was organized as a limited concern, with a capital stock of $6,000. The developed a complete line of woodworking machinery, and by 1892 they had 42,000 square feet of space, and a capital stock of $225,000. At that time the company officers were John H. Millspaugh, chairman; F. H. Sweet, general manager; Thomas Millspaugh, secretary and treasurer. From ninety to one hundred men were employed.

Williamsport Machine Co. was one of the eleven companies that merged in 1897 to form American Wood Working Machine Co. Williamsport's jointers, at least, continued to be made by the merged company. A "Happy Thought" planer badged with both the Williamsport and American names is reported.

  • Information on the "Happy Thought" planer came from a posting to the OWWM forum.
  • We have not found any patents granted or assigned to any of the principals post-dating the dissolution of Millspaugh, Rowley & Millspaugh (Fred Sweet did receive some patents as late as October 1882, but these were all assigned to Rowley & Hermance). Based on patent dates seen on machinery from this maker we have identified a handful of patents they have used.
