History
The Rotolactor was the first invention for milking a large number of cows using a rotating platform.[1] It was invented by Henry W. Jeffers.[1][2] The Rotolactor was initially installed in Plainsboro, New Jersey.[1] The rotating mechanical milking machine was first used by the Walker-Gordon Laboratories dairy and was put into operation on November 13, 1930.[1]
Description
The Abstract of the 1930 Cow Milking Apparatus (Rotolactor) patent states:
"The object of this invention is to provide an apparatus whereby an indefinitely large number of cows may be milked successively and largely automatically..."[3]
The Rotolactor held 50 cows and could produce 26,000 quarts of milk.[4] After each cow received a bath, their udders and flanks were cleaned.[5]
The August 1931 issue of the American Journal of Public Health and the Nation's Health described the Rotolactor as an advance in cleanliness and hygiene for milk production.[5]

Legacy
The Rotolactor was featured at the 1939 New York World's Fair in the Borden's exhibit.[6] The Walker-Gordon farm in Plainsboro later became a museum.[7] The farm building in Plainsboro containing the Rotolactor had an observation room to accommodate visitors, including large groups of school children.[4]
A 1930 film was titled: "New Jersey. 'The Rotolactor' - hygiene's latest - automatically washing and milking 50 cows at one time in 12 1/2 minutes - inaugurated by Mr. Thomas Edison."[8]
The Walker-Gordon farm stopped producing dairy products on June 18, 1971.[6]
