The motion is driven through a connecting rod with a discon-nectmg device from a shell cam fixed on the pick-cam shaft. Astud is bolted to the loom side, forming a bearing for one end of asmall lever which carries two studs at the other end, one on eachside. One of these studs works in the shell-cam, and the connect- 181 168 WEAVING iiig rod, A, (Fig. Ill) is attached to the other. At the upper endof this connectiDg rod, A, is attached this disconnecting device inthe form of a slotted lever, B, with a semi-circular recess in whicha stud, D, is held during the operation of the motion, this studbeing fixed at the end of the elbow lever. Ordinarily the discon-nector fits over the stud, and as the connecting rod moves up anddown the lower part of the elbow lever moves with it, thus causingthe uppe
