June is National Dairy Month so here’s a cow story from the December 15, 1930, issue of Farm Machinery and Equipment magazine.

The Last Word in Milking Efficiency
Walker-Gordon Farms of Plainsboro, New Jersey, a subsidiary of the Borden Company, are one of the oldest and largest milk producing farms in the world. The new Rotary Combine Milking System was conceived by Henry W. Jeffers, president of Walker-Gordon, after many years of research, while the milking equipment was developed and installed by the DeLaval Separator Company of New York City. The accompanying diagram, together with the following description, describes how the system operates. 

In brief, this new milking system applies the well-known industrial principle of bringing the work to the operator. In this case, the cows are brought to the operators instead of the operators going to the cows.

The new milking system consists of a revolving platform upon which are placed 50 stanchions. The platform revolves slowly, completing a revolution in 12-1/2 minutes.

The platform is housed in a beautiful new building which not only contains the milking system but a complete set of offices and laboratories. The interior of the building is beautifully tiled and in the center of the platform is a large glassed-in observation room, where visitors may observe the milking operation.
At the Walker-Gordon farm more than 1500 cows are maintained in individual barns of 100 each. The barns are connected by a central covered passageway, which in reality converts all the barns into one. 


The cows are brought to the Rotary Combine Milker and are conducted to the revolving platform through a tiled passageway. As the cow comes to the end of this passageway, she steps onto the revolving platform and one after another does so until all the stanchions are filled.
