Abstract

The method of washing industrial articles, involving the steps of placing the articles to be washed on a platform rotating at a predetermined speed in an enclosure; directing a series of streams of water on said articles, said streams of water issuing from nozzles on a rotating spray head, whereby through the rotation of the articles and the rotation source of the streams of water, variation in the incident angles of the streams of water impinging on the articles is greatly increased to produce a scrubbing, scouring, or lifting effect on dirt and foreign matter present on the articles being washed.

Claims

2. A method of washing an article comprising the steps of rotating at least one article to be washed, directing at least one moving stream of wash liquid against the article so that the stream impinges on a portion of the surface of the article, and controlling the movement of the stream with respect to the rotation of the article so that the portion of the surface on which the stream impinges rotates with the surface thus scouring the portion with a stream of wash liquid as the portion tracks with the surface of the article.

3. A method of washing articles in accordance with claim 2 and further including the step of simultaneously varying the angle of incidence of the stream upon the portion as the portion rotates with the surface of the rotating article thus scouring the portion with a stream of wash liquid having a constantly varying angle of incidence as the portion tracks with the surface of the article.

4. A method of washing articles in accordance with claim 3 in which the stream of wash liquid is a rotating stream.
