Abstract:

An apparatus for connecting a waterway, having a nozzle, to various sections of an aerial ladder. The connecting apparatus comprises an off-set cam within a cylindrical sleeve. One end of a connecting link is attached to the cylindrical sleeve. The other end fits within the clevises attached to the different sections of the ladder and has an aperture for receiving a clevis pin which is passed through the clevis and connecting link to attach the waterway to the selected ladder section. To firmly lock the waterway to the ladder section, a rotatable shaft, supported by bearings and having one end attached to the off-set axis of the cam, is rotated by means of a handle located on the exterior of the bracket. The rotation of the shaft and cam urge the waterway bracket against a step on the selected ladder section and thus securely lock the waterway in place.
