Edward Potts

Edward Potts (2 March 1839 – 15 April 1909) was an architect who practised in Oldham, Lancashire, England.

Biography Potts was born on 2 March 1839 in Bury, Lancashire. He moved to Oldham and designed many of the town's Cotton mills and was ranked with P. S. Stott as the greatest mill architect of Victorian Lancashire. Potts and his partnerships were responsible for the design and build of 200 mills, sixteen of which were in Oldham. One such mill is Textile Mill, Chadderton built in 1882.

Mills of this period were constructed with fireproof floors. These were principally triple brick arches, but Potts pioneered the use of 7" thick concrete floors. On 3 March 1884 he attempted to patent this new method of constructing fireproof floors and ceilings. The patent was rejected, and it was rapidly adopted by other architects. The seven inch floor was more rigid than a 12" brick floor, so preserved the alignment of the spinning mules, thus saving power. However the concrete floor however required a closer grouping of supporting columns, which restricted the size of the machines. To solve this, he introduced transverse steel girders into the design, supported on steel lintels above the windows. Thus there was no lateral thrust on the walls, and the windows became square headed and abnormally wide.
