1892 'The business carried on by this able and experienced mechanician was founded in quite a small way at Salford, in 1869, by a Mr. Slater. Ten years later Mr. Hans Renold became sole proprietor of the concern, and under his energetic management the business speedily began to develop at such a rate that it had to be transferred to its present address. Some idea of the manner in which this concern has advanced may be gathered from the fact that Mr. Renold now gives employment to no fewer than one hundred and fifty hands, while he has upwards of one hundred and thirty machines at work in his establishment producing his special improved chains for bicycles and tricycles, and also other kinds of steel driving chains for cotton machinery, elevators, cranes, electric traction, and other purposes. The premises, moreover, are being considerably enlarged, and when completed they will have a frontage of ninety-nine feet, and a depth of one hundred and twenty feet from front to rear, the block, containing six spacious floors, all fully equipped with steam-power machinery for the purposes of this notable industry. Another large building at the rear comprises the smithy and forge on the ground floor, with counting-house, offices, and stock-rooms on the next flat, and extra stock-rooms on the top floor. ....'<ref>[http://messybeast.com/1892-lancashire/1892-lancashire.htm] THE CENTURY'S PROGRESS - LANCASHIRE.

Chronology of this group:

1879 Company founded by Hans Renold. He purchased James Slater's business, a small textile-chain making business in Salford. In December he supplied a chain to James Starley.

1881 Mr. Hans Renold, patent chain maker, mentioned as having three rooms (one with power) at Medlock Sawmills, Chorlton-on-Medlock, and a tenancy of two more years.[1]

1881 He moved from Salford to Brook Street, Manchester, where a new factory, Progress Works, was subsequently built.

1884 Advertising for a Light Tool Fitter and an Improver. Address is Hans Renold, Green Lane, Brook street.[2]

1885 A patent for the block chain was applied for by Hans Renold but he decided to openly give his idea to the cycle trade for all to freely manufacture.

1888 The Hans Renold company were riveting the bearing pins in the assembled chain.

1889 The company designed and manufactured a purpose built plate hole-punching machine.

Designed and manufactured a machine for the Dry Tumbling (Jingling) of chain components.

1892 'The business carried on by this able and experienced mechanician was founded in quite a small way at Salford, in 1869, by a Mr. Slater. Ten years later Mr. Hans Renold became sole proprietor of the concern, and under his energetic management the business speedily began to develop at such a rate that it had to be transferred to its present address. Some idea of the manner in which this concern has advanced may be gathered from the fact that Mr. Renold now gives employment to no fewer than one hundred and fifty hands, while he has upwards of one hundred and thirty machines at work in his establishment producing his special improved chains for bicycles and tricycles, and also other kinds of steel driving chains for cotton machinery, elevators, cranes, electric traction, and other purposes. The premises, moreover, are being considerably enlarged, and when completed they will have a frontage of ninety-nine feet, and a depth of one hundred and twenty feet from front to rear, the block, containing six spacious floors, all fully equipped with steam-power machinery for the purposes of this notable industry. Another large building at the rear comprises the smithy and forge on the ground floor, with counting-house, offices, and stock-rooms on the next flat, and extra stock-rooms on the top floor. ....'[3]

1893 Hans Renold company were using hardened components.

1895 Designed and manufactured a machine for producing the Rotary Rivet on the ends of the chain bearing pins. The need for an Inverted tooth (silent chain) was apparent to Hans Renold and this resulted in his patent of 1895. Although his design of chain was superseded in later years by the silent chain with rocker joints, he made an impact in the introduction of such a chain. Designed and manufactured a machine for the Wet Tumbling (Jingling) of chain components

1896 Hans Renold company designed and manufactured a machine for the proof loading of their chain.

Introduced the 48-hour week when the general practice in engineering was 52 or more.

1899 The Hans Renold company introduced their patented feature of the end recess in the bearing pin. Introduced the round-ended necked (i.e. shouldered) bearing pin in their 1899 patent.

1899 Introduced a Works Canteen.
