\u2013 An example of the innovative engineering of the period working to quiet the cabinet refrigerator in the early 1930\u2019s, adopted here by Frigidaire\/Delco, \u2013 see also ID# 298
\u2013 The cradle mount provided Frigidaire with a dual function of motor quieting, as well as automatic belt tightening, afforded by a spring tension devices operating on the cradle to hold the belt in a taught position \u2013 see Reference 12
\u2013 The cradle motor mount by Frigidaire\/Delco would be one more significant step in an evolutionary sequence which would result, in the complete disappearance of the noisy, hazards, FHP motor, embedding it within the refrigeration system itself, the hermetic refrigeration motor compressor. [see examples classification code 4.01]
\u2013 Repulsion induction motor technology was above all a marvel of its time, a technology born of both science and the consumer market place, a classic formula for the innovation and diffusion of popular technology, throughout the balance of the 20th century and on in to the 21st. Scientifically, the work of Faraday and many others laid much of the theoretical foundations for electromagnetic devices, the marvel of the early 20th century [much in the same way digital devices became the marvel of the early years of the 21st]. The wonders made possible by alternating current energised, rotating magnetic fields and the electric and magnetic circuitry that made them possible would soon be exploited by those interested in their application in applied electro-motive technology, including Steinnmetz and others.
