Abstract
Improved control means for liquid feed is provided in a duplicating-machine of the type described in Specification 565,759 by attaching a mechanical device to the rock shaft whereby in one position the feed wick or wicks can be left permanently in contact with the moistening pad whether or not the cylinder is rotating, in a second position the liquid feed is alternately interrupted and re-established during the operation of the machine, whilst in a third position the liquid feed is completely interrupted.
