Torender this power capable of being varied at pleasure, theguide-blades are made movable round gudgeons or centresnear their points ; and a spindle K is connected with theguide-blades by means of links, cranks, &c., in such a waythat when the spindle is moved, the four entrance orificesare all enlarged or contracted alike. This spindle K, forworking the guide-blades, is itself worked by a handle ina convenient position in the mill ; and the motion is com-municated from the handle through the medium of a wormand sector, which not only serve to multiply the force of themans hand, but also to prevent the guide-blades from beingliable to the accident of slappin
