Fig. 87. Suction washer.
The suction washers for use in boilers are placed funnel side down. By means of these, the steam forming in the bottom of the boiler forces the water thru the clothes. Distribute the clothes evenly about the washer. Fill the boiler with water and add shaved soap. When set over a fire, the steam forming at the bottom raises the water in the funnel to the top and pushes it out thru the clothes, or raises the funnel and makes it beat upon the clothes.

Other machines combine the two methods of washing—forcing water thru clothes and rubbing them at the same time.
162. Cylinder Washers. Cylinder washers contain a perforated barrel-like device, into which the clothes are placed (Fig. 88). This cylinder has cleats on the inside to raise the clothes as the cylinder turns and drop them when they reach the highest point in it, back into the water, thus pounding water thru them and rubbing them against the side of the cylinder as they are raised. This is the type used in most laundries. A cylinder turned by an electric motor is made which can be placed in the stationary wash tub in small apartments. The tub then serves as the outer part of the washing machine.

163. Rotary Washers. In the rotary, or milk-stool, type of washer, sometimes called "Dolly" (Fig. 89), the stool-like contrivance which presses against the clothes must be turned half-way around in one direction, and then back the other way, to prevent twisting, tearing or otherwise injuring the clothes. The clothes are thus rubbed against the corrugated sides and bottom of the machine, and thru the water. Never put too many clothes in this type of machine because too tight packing causes the machine to tear them.
