In 1832 Ransom’s of Ipswich gained a license to produce and wholesale the Budding mower. This was an ideal situation as now the mowers were being sold within a well established network, Ransom’s being the principal producers of agricultural plough shares.
During the 1830s Ferrabee extended the range with 16in and 22in machines and by 1840 over 1,000 Budding mowers had been sold. Initially Ransom’s were acting as wholesalers from their showroom in Bury St Edmund’s but in 1837 they started to produce the machines under license.

Dr. Gorrie used an ice-making machine to blow cold air across his patients suffering from yellow fever and malaria in the 1830s.

vacuum

Patent for a vacuum cleaner in 1860. Daniel Hess appears to have been the first to patent (#29,077 U.S. issued July 10, 1860) a vacuum cleaner. Hess, a resident of West Union, Iowa, called his invention a carpet sweeper, not a vacuum. The machine did, in fact, have a rotating brush like other sweepers, however, the machine also possessed an elaborate bellows mechanism on top of the body to generate suction. The amazing thing about his machine was that it incorporated two “water chambers” to capture the dust and fine dirt.

So in 1947, the first microwave oven was introduced commercially. The first units were all big, about six feet tall and weighing 750 pounds.
