ABSTRACT:
Apparatus for continuously lubricating a conveyor belt with a mixture of water and soap or detergent during normal operation and for washing the conveyor belt during a preselected time interval after normal operation has ceased. Solenoid valves are interposed in water lines to a lubricating nozzle and wash nozzles to control the flow of water to the nozzles, and pumps are provided to inject soap or detergent into each of the water lines. During normal conveyor operation, electrical power is supplied only to the lubricating line solenoid valve and the lubricating line pump to produce a lubricating spray of water and soap or detergent from the lubricating nozzle which is directed onto the belt. When the master on-off switch is switched to the "off" position, a wash timer is actuated for a predetermined interval of time and cooperates with a relay to also enable the wash line solenoid valve and the wash line pump to deliver water and soap or detergent to the wash nozzle for cleansing the conveyor belt.
