Synopsis
Excerpt from Important Gin House Economies: Entered According to Act of Congress, in the Year 1881, by the Faught-Deering Cotton Gin Driver Manufacturing Company, Louisville, Ky
Why were the horses in this case both walking inside the line of the draught hook? Because there was not room for the outside horse between the draught hook and the post; because the draught hooks in this gin house were put into the levers at points which made it necessary to cut notches into each of the middle posts for the passage of the swingl'etrees.
We will now explain the harm of throwing the outside horses thus inside the line of the draught hook.
The lever from which this diagram was made measured 14 feet from the center of the master wheel to the draught hook, and the gentleman who owned the machine thought that his horses had the advantage of 14 feet levers. He was mistaken. The full or actual lever in any horse power is the length of a line drawn at right angles to the line of draught, and ex tending from that line to the center of the master wheel. Look now at dia gram No. 1, and observe that the line d is at right angles with the line 13 which is the line of draught, and then recognize that the length of this line at is exactly the length or value of the lever through which the power of the horses passes without loss to the master wheel. When in.the case now under consideration this line was laid upon the lever, its upper end touched the point represented by the star, and a moment's measurement demonstrated that the levers believed to be 14, were in reality but 12 feet in length.
