In about 1820 Henry Pershouse Parkes, from Dudley, established the Tipton Green Chain and Anchor Works (Staffordshire). The firm’s products included cables, chains, anchors and all kinds of forgings. In 1851 some tests were carried out on the company’s chains to demonstrate the tensile strength and fibrous toughness of the iron used in their production. The iron used on this occasion was supplied by Summer Hill Iron Works. Some of the chains were exhibited at the Great Exhibition in 1851 and also at the 1855 French Exhibition in Paris, where they won a prize medal. Henry Pershouse Parkes died in 1867 and appears to have been succeeded by his son, who had the same name. In 1867 the firm produced the largest anchor in the world, at that time. It was built for Brunel’s S. S. Great Eastern to the patented design of Joseph Beterley, of Liverpool. The anchor, which weighed eight tons was twenty six and a half feet long and cast from iron supplied by Bloomfield Iron Works. It was tested at Tipton Proving House and found to be able to stand a strain of 100 tons. Henry Pershouse Parkes junior went into partnership with Alexander Stewart Ross to form Henry P. Parkes and Ross. The partnership came to an end in 1885 and the company became Henry P. Parkes & Company. In 1904 the business was sold and became H. P. Parkes and Company, under the control of N. Hingley & Sons Limited, of Netherton. In 1944 the company’s name was changed to Richard Sykes and Son Limited, then in 1947 it became H. P. Parkes & Company Limited. The business went into liquidation in 1966.The item is significant as an early example of a well known prize winning British anchor and chain maker from the mid 19th century. The company name on the anchor indicate the period of manufacture making it a significant item prized today by collectors.Anchor 5 pronged metal with loop at bottom to attach anti-snag rope.
