Abstract

167,057. Thompson, W. P., (Union Special Machine Co.). June 24, 1920. Sewing-machines; feed by dogs, duplex.-An auxiliary feed-dog 2a is pivoted upon a main feedbar 3a, and is given differential to-and-fro movements by link-work actuated from the main feedbar. A plate 20 is pivoted at 21 to the machine frame, and is connected by a link 24 to a point 25 on the feed-bar. The auxiliary feed-dog is pivoted at 16 to the feed-bar, and a depending portion is connected by a link 18 to a pivot block adjustably secured in an arcuate slot 23 in the plate 20. The mechanism is arranged so that the pin 19 has a smaller movement than the feedbar, and consequently the upper serrated surface has a greater movement.
