Milking machine

vacuum milker in 1889, which hung suspended under the cow. He was granted a U.S. patent in 1892. • The Murchland milker, along with the famous "Thistle" milker, was extensively tested by the Highland and Agricultural Society of Scotland in 1898. • Numerous other hand pumped suction milkers were devised in the next thirty years, with the foot operated Mehring machine being, perhaps, the ultimate in pre- pulsator suction milkers. • Two cows could be milked at the same time, using this machine, with the operator sitting on it's bench, between the cows, and working the foot levers to provide vacuum. • The Mehring foot power machine was still marketed well into the 20th century and many were sold. A fine example was recently noted at one of the Brimfield shows, priced at $400. Pulsator • The pulsator was first introduced in the "Thistle" milker, using a steam driven vacuum pump.
