Abstract

The drive cam or crank is connected with the ram by a swing arm and a connecting rod which together form linkage which can travel out transverse to the line which connects the cam shaft with the ram hinge point. A tension rod is hinged to the drive cam and is connected with a swing arm which has a pivot point outside the centre and forms a second linkage with a plate and is connected with the hinge point of the first pair via levers. A bell crnak has one arm connected to a lever, the second arm being connected to the free end of the plate of the second linkage.
