Grandma and the Machine Age Grandma (Mrs. E. Lightfoot, 103 South Elberon, Atlantic City) "sticks to her knitting" beside an intricate new hosiery machine exhibited by Scott and Williams, Inc., Laconia, N.H., at the Knitting Arts Exhibition in Atlantic City, April 30 to May 4. The machine almost precisely copies the movements of grandma's nimble fingers in knitting a sock. In the time that her fingers take to go once around the stockings, the machine has knitted a whole sock and is ready for another despite the fact that many colored yarns are used and the pattern is complicated.
