Steam Engine Gooch Link and Valve Gear Arrangement

| View Cart ⇗ | Info

“As the speed increases, and the link is ‘notched up’, the lead is increased as the cut—off is shortened, and at high speed we have a large lead. With the Gooch link, the lead can be set for average running speed, and although a little too great for good work at slow speed.” —Derr, 1911
