  • Patent number: 5513667
    Abstract: A parts washer unit including a cleaning fluid storage receptacle which can be easily interchanged or exchanged with a like receptacle by the user of the unit. The unit includes a sink secured to the top of a support frame that defines a space accommodating the receptacle. The sink includes a drain opening which is aligned with an opening on one end of the receptacle when the receptacle is in place beneath the sink. A conveyor is secured to the frame which permits the receptacle to be readily transported to and from the desired location beneath the sink drain opening. A fluid circulating system includes a pump, a bag strainer, and hoses which extend in use into the sink for directing fluid over parts to be washed.
