Abstract
588,757. Sewing-machines. SINGER MANUFACTURING CO., Ltd. and HEGGIE, J. March 24, 1945, No. 7505. [Class 112] Feed, reversing.-In a sewing-machine having a four-motion feed-dog actuated in the usual way from a feed rock-shaft 10 and a feed-lift rock-shaft 14, the shaft 10 is actuated by means of an arm 18 thereon carrying the follower which engages a curved slot in stationary guide-block 21, the guide-block being mounted on an axis 23 parallel to the rock-shafts and being adjusted about this axis to reverse the direction of feed. In the arrangement shown the follower 17 comprises a two-armed member pivoted to the rockshaft arm 18, one arm carrying a roller engaging the guide-block 21 while the other is connected to the feed-actuating pitman 15. In the normal position shown, for forward feed, the slot of the guide-block is concentric with the shaft 10, so that the follower 17 is in effect rigid with the arm 18. To reverse the feed, the guide block 21 is tilted clockwise by depressing a plunger 26 which is pivoted to the middle joint of a toggle linkage connecting the guide-block 21 with a fixed pivot 31; a spring 32 attached to one toggle link restores the mechanism to the normal position when the plunger 26, or a detent which may be provided to hold it down, is released.
