Abstract

224,064. Armstrong, J. J. V., (Union Special Machine Co.). Oct. 13, 1923. Sewing-machines; duplex feed; feed, regulating; feed by dogs.-An auxiliary feed-dog is connected to be operated by the movements of the main feed-dog in such a manner that the extent of the feed may be varied by manual displacement of a part without stopping the machine. The main dog 14 on the arm 13 is given feed movements by an arm 16, mounted on a rocking- shaft 17 and pivoted at 15 to the arm 13. Vertical movements are given bv an arm 22 on a rocking shaft 21 engaging a block 23 beneath the arm 13. The auxiliary dog 40 is mounted on a bar 42 pivoted at 43 to the block 23 and having a slideway for a block connected by a link 41 to the pivot 15 of the arm 13. A spring-sustained arm 50 operated by a treadle is connected to the link 41 by a link 46 and may be actuated to vary the throw of the dog 40 by adjusting the position of the block in its slide.
