Abstract

202,898. Thompson, W. P., (Union Special Machine Co.). Dec. 6, 1922, Sewing-machines; frames.-The terminal portion of a tubular work-arm enclosing the looper &c. is formed in two parts, one part 14 being fixed to the body of the work-arm and the other part 15 pivoted to turn about an axis parallel to that of the The section 14 is secured to the arm by a bolt entering a slotted flange. The section 15 is connected to the section 14 by a pivot 19 entering lugs in the two sections and is latched in closed position by a catch 27 which may be forcibly disengaged by pressure applied to a thumb-hold 26 on the section 15. The sections are formed with end flanges 17<a> 25 which close the end of the work-arm. Thread is led to the threaded looper 9 along a slot in the workarm closed by a plate 31 and guided by a wire 33 to the heel of the looper.
