Chronology of this group:

1930 Merger of Hans Renold Ltd with Coventry Chain Co created Renold and Coventry Chain Co.[1] The new company had works in Manchester, Coventry and Birmingham, together with the former Brampton works at Calais. Chain production in the UK works was concentrated in Manchester and Coventry, and free wheel manufacture at Coventry was given up.

Arthur Brampton became chairman

1932 Chain supplied had chamfered plates, some being doubled chamfered (i.e. both sides). Patented the early design of bi-planar chain, (The patent being applied for in 1928).

1933 Supplied chain with a notched bush.

1933 Acquired the goodwill and stock in trade of Alfred Appleby Chain Co and Atlas Chain Co and the pressed lug part of the business of Charles H. Pugh Ltd[2]

1937 The Birmingham works and the Brampton cycle fittings business, which was concentrated there after the merger, were disposed of.

1939 See Aircraft Industry Suppliers

WWII During the Second World War, temporary premises were leased at Newton Mill in Hyde, Cheshire, for arms-related production.

1946 A new factory in Cardiff was acquired in 1946; this took over the wheel manufacturing department previously at Burnage and also manufactured chain clutches and couplings. An Australian manufacturing subsidiary was set up in 1949.

1947 Renold established its first green-field manufacturing operation overseas in Melbourne, Australia, and this was followed by the establishment of other owned sales and sometimes manufacturing operations in Austria, Denmark, Malaysia, New Zealand, Singapore, South Africa, Sweden and Switzerland.

1950 Renold and Coventry Chain Co chain plates had reamed holes.

The 1950s saw the expansion of Australian sales and manufacturing operations.

1954 The sales division and administrative services departments moved from Burnage to the new Renold House in Wythenshawe, Manchester. By this point the company had built up a world-wide sales organisation based on its selling subsidiaries and its agencies, which covered over seventy countries.

1954 Company becomes Renold Chains Ltd. and introduced their improved design of bi-planar chain with their patent.

1955 A factory in Burton-upon-Trent, Staffordshire, was acquired for the separate manufacture of conveyor chain and agricultural chain machinery.

1956 Renold acquired Anchor Chain Co of Oldham. With the introduction of nuclear power at Calder Hall, Renold Chains entered the Nuclear Age with the supply of control rod lifting chains.

1958 Wheel manufacture in Canada began in 1958.

1959 Merged with Perry and Co.

1959 Renold Chains Ltd. were innovators in the chain industry of progressive die tooling (i.e. follow-on tooling) in the manufacture of chain plates. Chain plates for pitches between 1.0" and 1.5" were being produced by this method. Smaller pitch chain plates had begun being produced by this process many years earlier.

1960s In addition to the Holroyd merger, the 1960s saw expansion in Europe.

1961 Engaged as manufacturers of driving chains and wheels for cycles, motor cycles, automobiles, conveyor and general power transmission equipment. 5,200 employees. [4]

1963 The company acquired the manufacturing companies Manufacture Lilloise de Chaines S.A., of Lille, France, and Arnold and Stolzenberg GmbH of Juliusmuhle, Germany, and established a new wheel manufacturing plant at Charleville-Mezieres in the French Ardennes. Renolds also gained an interest in local manufacture in Spain during this period. Sales companies were established in Spain, in 1962; Austria, in 1964; Denmark (Renold A/S, of Copenhagen) in 1965; Switzerland, in 1968 and Sweden (Renold Svenska AB) in 1969. Outside Europe, the decade saw the formation, in 1968, of Renold (Southern Africa) (Pty.) Ltd., of Pietermaritzburg, South Africa, a chain manufacturing company.

1964 A significant strategic development of the Renold Group was the acquisition of John Holroyd and Co and this marked the start of the transition from purely chain manufacture to manufacture and supply of a complete range of power transmission products and precision machine tools. Further acquisitions brought more gearing, couplings, clutches, brakes, variable speed drives and various hydraulic products into the Group.

1996 Renold acquires the Holset couplings business in Halifax, and renames the company Renold Hi-Tec Couplings.
