Abstract
The apparatus comprises a washing chamber and a washing brush on the end of a hose leading to a reservoir for liquid to be applied. The hose is connected to an outlet pipe of the reservoir having a one-way valve which is immersed in liquid in the reservoir and allows movement of the brush to pump liquid from the reservoir to the chamber. Liquid supplied to the chamber is collected in a sump, the overflow of which feeds the reservoir. A filter screen is positioned between the chamber and the sump, in which solid material precipitates, allowing liquid to be recycled. The apparatus can be used, for example, for removal of ink from a used screen, removal of stencil material from a used screen or application of a degreasing preparation to a screen prior to use.
