Snyder, Edna B. and Brunig, Morton P. (1931) A study of washing machines (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 56)
The purpose of this investigation was to study the performance and constructional features of various types of washing machines. The machines studied were of four types, classified on the basis of mechanical construction. The types were dolly, gyrator, cylinder, and vacuum. Eight machines were studied, four of the gyrator type, two of the dolly type, one of the cylinder type, and one of the vacuum type. The material reported in this bulletin includes the following: (1) cleansing action of various washing machines and relation of cleanness of fabric to length of washing period, temperature of water, and size of load; (2) wear on fabric; (3) heat retention; (4) constructional features adding to convenience of operation.
