Fig. 92. Washer and dryer.
The rapid turning of the inner tub for three minutes throws the clothing and water in them to the outside of the revolving center. This tub being perforated, lets the water thru while retaining the clothing. Thus, the clothes are wrung as dry as in a wringer of the roller type. If the machine is turned a longer time, the clothes can be wrung entirely dry.
172. Care of the Machine. When loading centrifugal wringers, put the heavy pieces at the bottom of the basket. Put articles in basket in bunches, and pack fairly tight. Do not have loose ends hanging out. Fold sleeves into garments. Load the basket full if there are clothes enough. A cover helps to hold the clothes in place. Load so that it runs even and does not wobble.
Never hold your hand on the extractor after it has started.
173. Combination Washer and Wringer. The centrifugal washer and wringer combined is built so that the basket can be lowered into a tub of water. The clothes rotating in water are washed. After this is accomplished, the cylinder is raised, and, when rotated, serves as a wringer of the centrifugal type.
Load the washer with fewer clothes than for wringing. Roll each garment into a bunch before putting it into the washer.
Centrifugal wringers are used also as dry-cleaning machines. For this use, they should be operated out of doors and at a slower speed than when water is used. Friction heats gasoline, causing it to evaporate rapidly. The friction between clothing, tub and gasoline when turned at a high speed may produce a spark which will ignite the gasoline.
