THE JAMIESON MILKER.

A MECHANICAL REVOLUTION.

The standard of our butter when it is placed on the markets of the world has a very real bearing on the prosperity of the Dominion, and any marked advance in tho methods employed in the course of manufacture has a direct influence on our main national source of revenue. One of the cleverest inventions applied to machine milking is embodied in the Jamieson improved milking machine which is daily being inspected by hundreds of dairy farmers at tne Auckland Winter Show. The main object of this invention is to overcome the disadvantages of flooding or contaminating the vacuum system with milk, which it has been commonly supposed his been caused by the milk splashing in the top chamber. The force of gravity was depended upon to bring the milk from the top to the bottom chamber by movement of slide or flap valves arid this would have ; sufficed were all cows to give cold water, but in dealing with milk at blood heat | drawn rapidly in the system, trouble was I caused by frothing, and it is here that the Jamieson Milker has brought about a revolution.. Froth cannot be removed from the top, or . receiving chamber of: any releaser by gravitation, ; but * the Jamieson machine has disposed of the problem by the alternate method of applying vacuum, first to the fop chamber, and then by the alternate route to the bottom chamber. The pulsator, the chief feature of the invention, consists of two rotating discs, one revolving against the other, the operation of the machine thus J being automatically regulated. The alj ternating routing of lihe vacuum naturally means a flushing of each chamber, and I as the.top chamber is connected with the j cow's teats, vacuum is always maintained there and to the teat, cup. It will therefora be understood: that such a check I system of automatic control" ensures a ! fool-proof machine, which the Jamieson • has undoubtedly proved itself under test. A point of interest to farmers is that the machine enables a clear judgment to be obtained upon tha return of every cow in the herd, the milk pipe system having one large releaser, and a number of sm*ll releasers at each " dummy " for the testing of individual cows. Thus at a lower cost the Jamieson provides, the farmer, with a more simple and a more reliable type of mechanical milker made possible by the simplest possible arrangement.
