It also has an opening throughwhich projects a pin, around which theeye of the bolt is bent. This pin is muchlarger where it goes through the platethan at either end ; the outer end is fas-tened by a set-screw in a fork to the leverE^ shown ; this lever is used to pull the up the lower jaw bends the iron enoughto offset it, so that the eye will be formedequally on each side of the bolt. When the rod is clamped and air ad-mitted to the large cylinder, the rackmeshing into the gear causes the head.
