Abstract

621,573. Sewing-machines. KELLER, J. May 30, 1946, No. 16509. Convention date, June 13, 1945. [Class 112] A feed dog drive mechanism, comprising two rock shafts operating a link and lever gear for the feed advance, and two levers for the feed lift, is arranged so that the feed dog remains parallel to the line of feed during its entire movement. The dog 10, mounted on a stirrup 11, is advanced by levers 6 on the rock shaft 3 connected to the stirrup by the link 8. The feed lift is obtained from the rock shaft 17 by means of interengaging levers 16, 18 which co-operate with the stirrup. One end of the lever 16 is connected to the rock shaft 17, and the other carries a roller 13 engaging a slot 12 in the stirrup. The lever 18, pivoted at 19, engages a slot 161 in the lever 16, and carries a roller 14 running in the slot 12. The pivot 19 is eccentrically mounted on the machine frame to, permit accurate setting of the mechanism.
