1 Calvin Brooks' brother Isaac had been investing money in the efforts of William Dunn who had patented train car couplers earlier and was now patenting an improvement upon them (see W1707, W1711, W1712, W2656, W2667, W2671, W2675, W1714, W1716, W1721, W1741). Unfortunately, Dunn mishandled the business of selling his patents and machinery. He promised to repay Isaac $600 but it appears that he did not accomplish this either and the McQuestens considered launching a suit against him. For more on Dunn, see W2554a.
