Abstract
A drilling machine comprises a rotary motor mounted to an assemblage of rigid bar linkages. Means are provided for moving the linkages relative to each other. The linkages are connected together in a configuration which ensures that as the linkages move relative to each other the rotary motor moves along a vertical line. Preferably the machine will be mounted on a suitable vehicle. The invention extends to a method of drilling.
