Rinsing trough

The trough in which formes are rinsed in is a combination of two troughs. The smallest and deepest contains the water, and in some offices has an iron ladle chained to the near upper corner to prevent its being displaced; the shallow part being used to lay up the forme in. They are both lined with lead, and the shallow one has a loose deal bottom to preserve the lead, and in general is bound with iron, particularly at the front, to prevent the edge of the chase when being lifted upon the letter-board from cutting the lead. They both have an opening with a short pipe at the bottom to convey away the water, that in the water trough having a brass plug in it for the convenience of letting the water off to clean it out. They stand on a frame which is usually placed on a platform raised at the edge a few inches, lined with lead, styled the sink, with loose bottom of boards which leads into a pipe for drainage.
