A bright bazaar, the New York Electrical & Industrial Exposition which began last week, showed that of the 25,000 practical applications of electricity the ones most vigorously exploited are those most useful to housekeepers. They constitute two large groups dependent upon electricity’s change into 1) power and 2) heat.
Power Appliances. Electrical refrigeration commercializes a device which the British scientist Lord Kelvin built 30 years ago. With a pump he compressed gases; the gases lost heat. He permitted the gases to expand into a chamber; they absorbed heat from neighboring objects. Such objects naturally grew colder with the abstraction of their heat.
Upon those essentials are all electrical refrigerators built. Some brands exhibited were:
Frigidaire Kelvinator Copeland Universal Zerozone Ice-maid General Electric Motor driven, also, were:
WASHING MACHINES CLEANERS Graybar Eureka
Savage Hoover
Apex Westinghouse and sewing machines, manglers, fans, floor polishers, etc.
Heating Appliances. Copper wire carries electric energy with very little wastage. A wire made of chromium-nickel or similar alloys, on the other hand, resists the passage of electricity and gets hot. Upon this fact were created the many heating devices displayed at the show: Flat Irons Hot Pads Manglers Toasters Grills Percolators Stoves Waffle Iron— Heaters Curling Irons Radiators Sterilizers and a new device for pressing trousers.
Some important heat appliance brands displayed were: Westinghouse Simplex American Beauty Sunbeam Dover Empire Hotpoint Apex
