ABSTRACT:
A water fountain control wiper unit of resilient material having a tubular portion on one edge that is slit for fitting over the edge of the fountain tray. The wiper has sufficient width so that a relatively flat surface tangentially adjacent the water fountain roller is biased against the water fountain roller to remove water upon rotation of the water fountain roller. The wiper unit has a length substantially shorter than the length of the water fountain roller so that one or more of the wiper units can be positioned along the length of the fountain roller to provide selective water removal, and the connector on the wiper blade unit allows the wiper blade to be quickly and easily mounted on or removed from the connected position on the edge of the water fountain tray.
