A simple wringing machine can be made in this manner. Obtain two indiarubber rollers mounted on spindles; remove the cogs, as these are not used. Also obtain two slotted plates as A (see sketch), made from l 1/4 -in. by 3/16 -in. iron; the slots in the plates must be of a size to fit easily on the spindles of the rollers, the distance apart being regulated by the diameter of the rubber. Also make two springs from 1-in. by 3/16- in. steel, shaped something like B. Two clips, as C, will also be wanted; the top part must be drilled to take a bolt D, a corresponding hole being made in the two springs. One leg of each of the clips must also be drilled and tapped, and a thumbscrew fitted, as E. To fit the parts together, first place the two roller spindles in the slots in plates, then spring on the impression springs, one on each end. Now measure the distance from centre to centre of the two springs, and drill a piece of flat iron so that it will fit between the springs and the clips, as shown at F: this will keep the springs rigid sideways. The clips with thumbscrews are for fixing the machine to the washtub, and, being fixed by one bolt only, will swivel round so as to be used at either angle. One of the roller spindles should be squared or threaded for a winch handle.

All the ironwork must be well painted or given two good coats of bath enamel.
