The ''Bender Machine Works'' in Hayward, WI is a dairy equipment manufacturer that played a major role in the history of the dairy farming business in the United States from the 1950s to the 1980s, producing milk pipeline and milk transfer cart components, and washing/vacuum-releasing equipment. The company continues to be in business but now focuses its manufacturing on private label electromechanical milk pipeline washing systems. ==Washer/Releaser and Step-Saver== The Bender Washer/Releaser was a vacuum-operated device first invented and patented by Lloyd Bender of Hayward, WI, USA in the 1950s, used to both wash dairy milking equipment and to transfer milk from piping containing a vacuum, into a storage tank at normal atmospheric pressure. As a non-electric pneumatically operated device, the washer/releaser could be used on small dairy farms without electricity that used an engine to supply milking vacuum, and used well water to cool milk. The Washer/Releaser could be used in association with both dairy pipelines and the ''Step-Saver'', a milk transfer cart used with bucket milkers. The Step-Saver and the Washer/Releaser were once extremely common in the 1960s to 1980s on small family dairy farms in the United States, to reduce the labor of bucket milking before the milk pipeline became more popular. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bender Machine Works」の詳細全文を読む スポンサード リンク
