KNOTTS’ PATENT DRY-AIR CIRCULATION CARS.

The question of carrying any long distance dead meat, fish, milk, or other perishable articles without deterioration is the point of success and profit. Many are the contrivances in vogue at present, and amongst'them-iscKnotts’ dry pure air sj'stem of refrigerating, which the inventor states will keep perishable articles in an unaltered state in any climate for an indefinite period without freezing. This system has been applied to railway cars, which are manufactured for the patentee, by the Swansea Wagon Company, Limited. Mr F. G! Andrews, of Foxton, has been appointed sole agent in New Ze iland for these cars. The principle is very simple, and consists of a tank as each end of the car containing an uncongealable liquid which produces the required temperatures.- By means of a blower worked by the revolving of the axles air is drawn into the tanks, and forced through a series of tubes distributed throughout the car. This cold air eventually passes through layers of charcoal before it finally enters the body of the car where the meat, etc., is carried. The patentee claims that the air in the car is not only perfectly pure, but is without dampness, and meat or other perishable articles can be carried long distances in perfect safety. Some of the cars have been supplied to the New South Wales Government. The British Mercantile Gazlette says “ There is no doubt that Mr Knott’s dry-cold and purified air invention is but another link in the great chain, which is binding the Mother country in closer relationship with the colonies.” -
