Abstract

547,696. Sewing-machines. JACKSON, L. MELLERSH- (International Button Hole Sewing Machine Co.). March 4, 1941. No. 8755/42. Divided out of 547,678. [Class 112] A needle-bar 35 siides in a sleeve 34 mounted on cross pivots 36, 37 and is laterally vibrated in two directions at right angles from cam-grooves 54, 55. The shuttle'and shaft are given an axial movement corresponding to the longitudinal movement of the bar 63 by means of a lever 115 fast on the shaft 77 carrying the lever 78 and a pair of collars 112 on the shuttle shaft 110. The cyclical position of the shuttle beak is advanced and retarded .to suit the transverse vibration of the needle by the relative displacement of helical toothed wheels 121, 122 by which the shuttle shaft is driven from a shaft 124. The wheel 121 is held from axial movement with the shuttle shaft 110 and the wheel 122 is carried by a sleeve 135 which is moved axially upon the shaft 124 by a third cam groove 56 acting through a quadrant lever 146, link 143 and a lever 138. The shuttle is supported and driven by six levers 99 carried by the shaft and caused to move into and out of recesses in the shuttle body by a cam surface enclosing the levers and formed within a non-rotating block 96. The block 96 and a throat plate 195 attached to it move axially with the shuttle shaft 110. The bobbin-case is held from rotation by the alternative engagement of arms 178 with a groove 177 in the bobbin-case front. These arms are carried on a shaft 170 which is oscillated by means of a lever 179 and a crank-pin 181 which may be adjustable.
