During the time these tools were building I was waited upon by Mr. Chas. B. Richards, who was then removing from Hartford to New York to establish himself as a designer of machinery, and who brought me a letter from Geo. S. Lincoln & Co. I was at that time engaged in scheming as well as I could a machine for drilling the arms and balls and counterweight and spindle of my governor, and immediately employed Mr. Richards to assist me in getting out the drawings for this machine. This he did quite to my satisfaction, and the machine was made by Geo. S. Lincoln & Co., Mr. Pratt, for so many years head of the firm of Pratt & Whitney, afterwards the Pratt & Whitney Company, being then their foreman; so that all my tools from that concern were made by Mr. Pratt. He also cut for me superb iron patterns for the governor gears. This machine always interested me very much. It solved every problem which was involved in the perfect and rapid performance of these operations. It had two parallel spindles running horizontally in the same plane, one fixed and the other adjustable. Distance pieces laid between the spindle heads insured the equal length of the arms of all governors of the same size. The table was made with a back to it, so that, a parallel block being laid on the table behind the arms, these were always brought in position parallel with its back. The arms were supported on blocks of proper height. These provisions insured that the joint-holes, which were drilled simultaneously, should intersect the axes of the arms and of the balls and spindle at right angles. This machine fitted up all the governors that I ever made. I gradually built up an excellent business in their manufacture, on account of the extreme pains taken to produce perfect work, so that the governors always gave the highest satisfaction.
