Abstract

814,055. Sewing machines. PFAFF, A. G., G. M. July 12, 1957 [July 17, 1956], No. 22097/57. Class 112 In a double loop sewing machine the feed dog 8 is displacable horizontally out of its operative position so as to afford access to the looper 4 to facilitate threading of the latter. As shown, the feed dog is pivoted about a vertical pin 17 to the feed 'bar 7 and is held in operative position by a spring-loaded ball catch 21. The feed bar is pivoted to a crank 10 carried by the feed advance shaft 9, and is connected by a pivotal link 13 to a crank 12 carried by the feed lift shaft 11.
