Des Moines Iowa Homestead (Newspaper) - May 16, 1912, Des Moines, Iowa
The Iowa Homestead Des Moines Iowa thursday May 16, 1912. A Victory for mechanical science How the milking machine the dream of centuries has become a real Ity an invaluable Aid to the Dairyman and a Factor in sanitary Dairying ome one has rightly said that the night Mare of the the important feature of milking machine. Dairyman has been to get and keep Good reliable cleanly gentle efficient milkers who would stay right on the Job twice a Day 365 Days a year. The Dairyman has been called upon to face still another prob Lem of attaining the seemingly unattainable. The Progress of human welfare demands of him that the product of his Dairy be free from Only that it contain no foreign substances but that it retain its original Freedom from the tainting doors and disease Breeding gases that Are incident to and inseparable from the Dairy barn. A standing joke of centuries has been a wish for a milking and the Mere possibility has been and perhaps still is to some extent looked upon with the same seriousness As were the accomplishments of Aladdin s lamp. But the joke no longer exists. Persistence and a Wise application of the principles of science have brought to the necessary state of perfection a mechanical Milker which requires the supervising hand of Man Only in the adjustment and in the care of the product. Its use reduces the help required in the care of a Herd and thus in a measure insures better care of the animals. It disposes of the Drudgery that has been repugnant to Man from time immemorial and so improves his Frame of mind and produces a reflected temperamental Equality on the part of the animals with which he is associated. Cows under the improved conditions Are More Content and devote a greater proportion of their physical and nervous energies to the production of milk. The process of milking with the mechanical Milker reduces the possible absorption of obnoxious flavors to a minimum As the milk has no direct exposure to the air in which the milking is done and it is fully protected from even the smallest particles of dust. The world is begging for cleaner milk than can be gotten by the most careful and cleanly of hand milkers. It is not without the Range of possibilities that the efforts of bacteriologist and Sani tary authorities May re sult in legislation favor Able to the More Gen eral use of the Mechan ical Milker. The illustrations which appear herewith Are made from actual photographs of a mechanical Milker. They give a Mere hint of the truth of the claims made for them that the Cost of milking cows can be reduced 75 per cent that one operator with a boy to carry milk and assist can properly milk 100 cows in less than two hours that the improvement in the cows condition resulting from the thorough Quick and regular work of the Milker will induce an increased milk production of a purer product at a lower bacterial count and of much greater value. A Brief description of the mechanical milk or May be of interest. The milking is done by the application of pneumatic pressure. The equipment is really quite simple and comparatively inexpensive. The More important feature is an air pump which a two or three horsepower of any sort will easily operate. The pump May be located at any convenient Point within 500 feet from the place where the milking is done. A Cir Cuit of two Small Iron pipes reaches from the pump to the farthest Point where the milk ing is done. In the barn these pipes Are so placed As to facilitate the attachment of the flexible tubes connecting them with the milk bucket and teat cups. The teat cups consist of a rigid Metal Shell or tube surrounding a rubber diaphragm or gland. This flexible rubber gland is the equivalent of the human hand in milking except that it is far More flexible More gentle and More persistent. It is operated by air pressure applied in such a Way that it May be worked at will inwardly or outwardly As is determined by the adjustment of the control Ling valve. This soft flexible member at the proper moment closes on the teat on All sides As your Tongue does when you place your Finger in your Mouth and suck it. As the air pressure is increased the rubber encloses the teat More tightly but always gently and gradually forces it up from the Bottom towards the top. At the proper moment the air pressure is relieved the rubber is brought Back to Normal position and the vacuum always maintained in the milk bucket communicates through the milking tube to the teat and the milk flows freely and rapidly. This process is repeated about fifty times per minute thus main Taining the gentle upward Massage squeeze of the teat towards the udder and the rapid effective discharge of the milk Leav ing the udder completely emptied and both teats and udder in a soft pliable Comfort Able Cool and natural condition. A constant vacuum is maintained in bucket and tubes leading to the teats. No air at any time enters these thus accounting for the extraordinarily pure character of the milk. The vacuum or suction on the teat is momentarily Cut off while the upward squeeze is being Given by the pres sure outside the rubber diaphragm forcing it together below the teat. On removing the teat cups from the the vacuum is still maintained in the milk bucket but is relieved at any moment at the discretion of the operator after the bucket has been carried into pure air. All parts in Contact with the milk Are very simple few in number and easily and thoroughly cleaned in but a few moments. There is no hidden or difficult surface to concluded on Page 14.
