label: Description
content: The central part of Holland’s patent concerned the stop motion mechanism on a silk thread making machine. If a thread broke, a small rod, connected to each of the threads by bent wires, would drop. A lever, to which the rod was attached, would come in contact with the drum and then stop the machine by throwing it out of gear. Also included in the patent was a method to change the twist of the silk thread by using a short cylinder.
