Friar's Green Mill
in Warrington
1825 The mill was occupied by Birch, De Iongh & Co, Friar's green, cotton spinners[1].
1828 Mill advertised for sale. A detailed listing of equipment included 'ten patent self-spinning mules, on De Iongh's principle, the purchasers of which will have the privilege of using the same;'[2]. This is significant because Maurice De Jongh had obtained a patent for a self-acting mule on the same day as Richard Roberts, in 1825.
