Marked "Goodrich Sales Co, Chicago" and more on the back of the blade, this iron can be adjusted to three different lofts. Just rotate the knurled ring at the base of the hosel to raise and lower a pin inside the hosel. This pin or "plunger" fits into any of the three holes in the top of the blade under the hosel. The bottom of the blade is attached by a special screw that allows the blade to pivot forward or backward, so any of the three lofts can be selected by lining up the corresponding hole underneath the raised pin. The Four slots in the hosel lowered the weight of the hosel to compensate for the added weight of the mechanism, to keep the head from being too heavy.
This club was based on a patent issued to Charles Curry of Chicago, Illinois on January 6, 1914, and it bears this 1914 patent date. Latimer Goodrich, who received a patent for this very club in 1918, described it as an improvement on Curry's 1914 patent. For more information, see TCA2 V2 p452.
