A new firefighting nozzle has a series of moveable vanes that extend inwardly from a peripheral wall of a base. The inner side of the vanes extends between &#x215b; and &#x215c; of the diameter of the central channel. The vanes rotate between a linear position, in which the vanes are generally parallel to the direction of the channel, and a vortex position, in which the vanes are significantly angled with respect to the direction of the channel. In the linear position, smooth bore linear flow is produced. In the vortex position, any of a range of fog patterns are produced. An externally mounted controller connects to the vanes and enables a firefighter to change the shape of the nozzle's spray without interrupting the flow. The controller and base have a series of pins that slide in a spiral groove and cause the shaper to move axially with respect to the base when the shaper is rotated about the base. Radial stems that ride in a circumferential slot translate that axial movement into rotation of the vanes.

A new firefighting monitor has multiple pivoting conduit segments and a synchronization mechanism with engaging faces that automatically restrain pivoting of an intermediate conduit segment with respect to an upstream conduit segment when the downstream conduit segment is pivotable with respect to the intermediate conduit segment, and automatically restrain pivoting of the downstream conduit segment with respect to the intermediate conduit segment when the intermediate conduit segment is pivotable with respect to the upstream conduit segment. In a variation, an intermeshed gear train causes a downstream conduit segment to pivot proportionately with respect to an intermediate conduit segment as the intermediate conduit segment pivots with respect to the upstream conduit segment.
