Abstract
Improvements in or relating to Automatic Washing Apparatus"
ABSTRACT OF THE DISCLOSURE
An industrial washing machine for washing each of a continuous flow of production components in turn has a group of jets mounted in a respective manifold casing at each of one or more washing stations. Each mani-fold casing is hinged to fixed structure and is held in abutment with a locator stop by a toggle lever latch.
Each jet is precisely located in position for use by the combination of the respective locator stop and hinge and can be swung from that position when the respective latch is released in order to facilitate access to the jets for cleaning and/or access to a production compo-nent which is supported at the respective washing station for cleaning so that, if such a production component should be displaced, relocation is facilitated.
The jets in each manifold casing have a smaller diameter and longer bore than do the remaining jets in the washing section of the machine. Washing fluid fed to each manifold casing is passed first through primary and secondary filters whereas the washing fluid fed to the other jets is passed through the primary filters only.
