Carr's Disintegrator
Carr's disintegrator (also known as Stedman in the U.S.; Hubner, continental Europe) was a 19th-century "toothed crusher" or pulverizer invented by Thomas Carr (engineer), Thomas Carr of Montpelier, Bristol, England, and patented in Great Britain in 1859. It used to the best advantage the energy which was transmitted to it, which explained its extraordinarily high output compared with some of the other disintegrators. Carr's disintegrator was the best-known of its era. Several different models were built according to the desired outcome. The machine was mostly used for the pulverising of such substances as superphosphates and other materials that would form pasty masses when subjected to pressure, or would clog the grooves of an ordinary mill. It consisted of two or more circular discs studded with beaters revolving within a casing or box in opposite directions on the same line of shafting. The velocity of the peripheral row of beaters was about per second, at which velocit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carr's Disintegrator With Cover Removed (The Mechanical Engineering Of Collieries, 1905)
Carr's is a British biscuit and cracker (food), cracker manufacturer, currently owned by Pladis, Pladis Global through its subsidiary United Biscuits. The company was founded in 1831 by Jonathan Dodgson Carr and is marketed in the United States by Kellogg's. History In 1831, Carr formed a small bakery and biscuit factory in the England, English city of Carlisle in Cumberland; he received a Royal warrant of appointment (United Kingdom), royal warrant in 1841. Within 15 years of being founded, it had become Britain's largest baking business. Carr's business was both a mill and a bakery, an early example of vertical integration, and produced bread by night and biscuits by day. The biscuits were loosely based on dry biscuits used on long voyages by sailors. They could be kept crisp and fresh in tins, and despite their fragility could easily be transported to other parts of the country by canal and railway. Jonathan Carr protested against the Corn Laws, which placed steep tariffs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
