    b. 4 October 1788 Smithfield, Pawtucket, Rhode Island, USA
    d. 1865 Washington, DC, USA
    [br]
    American textile machinist who applied the differential motion to roving frames, solving the problem of winding on the delicate cotton rovings.
    [br]
    He was the son of Benjamin and Isabel Arnold, but his mother died when he was 2 years old and after his father's second marriage he was largely left to look after himself. After attending the village school he learnt the trade of a carpenter, and following this he became a machinist. He entered the employment of Samuel Slater, but left after a few years to engage in the unsuccessful manufacture of woollen blankets. He became involved in an engineering shop, where he devised a machine for taking wool off a carding machine and making it into endless slivers or rovings for spinning. He then became associated with a cotton-spinning mill, which led to his most important invention. The carded cotton sliver had to be reduced in thickness before it could be spun on the final machines such as the mule or the waterframe. The roving, as the mass of cotton fibres was called at this stage, was thin and very delicate because it could not be twisted to give strength, as this would not allow it to be drawn out again during the next stage. In order to wind the roving on to bobbins, the speed of the bobbin had to be just right but the diameter of the bobbin increased as it was filled. Obtaining the correct reduction in speed as the circumference increased was partially solved by the use of double-coned pulleys, but the driving belt was liable to slip owing to the power that had to be transmitted.
    The final solution to the problem came with the introduction of the differential drive with bevel gears or a sun-and-planet motion. Arnold had invented this compound motion in 1818 but did not think of applying it to the roving frame until 1820. It combined the direct-gearing drive from the main shaft of the machine with that from the cone-drum drive so that the latter only provided the difference between flyer and bobbin speeds, which meant that most of the transmission power was taken away from the belt. The patent for this invention was issued to Arnold on 23 January 1823 and was soon copied in Britain by Henry Houldsworth, although J.Green of Mansfield may have originated it independendy in the same year. Arnold's patent was widely infringed in America and he sued the Proprietors of the Locks and Canals, machine makers for the Lowell manufacturers, for $30,000, eventually receiving $3,500 compensation. Arnold had his own machine shop but he gave it up in 1838 and moved the Philadelphia, where he operated the Mulhausen Print Works. Around 1850 he went to Washington, DC, and became a patent attorney, remaining as such until his death. On 24 June 1856 he was granted patent for a self-setting and self-raking saw for sawing machines.

    b. 1712 Scotland
    d. 1798 England
    [br]
    Scottish manufacturer who installed the first Boulton \& Watt rotative steam-engine in a textile mill.
    [br]
    George Robinson is said to have been a Scots migrant who settled at Burwell, near Nottingham, in 1737, but there is no record of his occupation until 1771, when he was noticed as a bleacher. By 1783 he and his son were describing themselves as "merchants and thread manufacturers" as well as bleachers. For their thread, they were using the system of spinning on the waterframe, but it is not known whether they held a licence from Arkwright. Between 1776 and 1791, the firm G.J. \& J.Robinson built a series of six cotton mills with a complex of dams and aqueducts to supply them in the relatively flat land of the Leen valley, near Papplewick, to the north of Nottingham. By careful conservation they were able to obtain considerable power from a very small stream. Castle mill was not only the highest one owned by the Robinsons, but it was also the highest mill on the stream and was fed from a reservoir. The Robinsons might therefore have expected to have enjoyed uninterrupted use of the water, but above them lived Lord Byron in his estate of Newstead Priory. The fifth Lord Byron loved making ornamental ponds on his property so that he could have mock naval battles with his servants, and this tampered with the water supplies so much that the Robinsons found they were unable to work their mills.
    In 1785 they decided to order a rotative steam engine from the firm of Boulton \& Watt. It was erected by John Rennie; however, misfortune seemed to dog this engine, for parts went astray to Manchester and when the engine was finally running at the end of February 1786 it was found to be out of alignment so may not have been very successful. At about the same time, the lawsuit against Lord Byron was found in favour of the Robinsons, but the engine continued in use for at least twelve years and was the first of the type which was to power virtually all steamdriven mills until the 1850s to be installed in a textile mill. It was a low-pressure double-acting condensing beam engine, with a vertical cylinder, parallel motion connecting the piston toone end of a rocking beam, and a connecting rod at the other end of the beam turning the flywheel. In this case Watt's sun and planet motion was used in place of a crank.

  • 4 Pickard, James

    [br]
    fl. c. 1780 Birmingham, England
    [br]
    English patentee of the application of the crank to steam engines.
    [br]
    James Pickard, the Birmingham button maker, also owned a flour mill at Snow Hill, in 1780, where Matthew Wasborough installed one of his rotative engines with ratchet gear and a flywheel. In August 1780, Pickard obtained a patent (no. 1263) for an application to make a rotative engine with a crank as well as gearwheels, one of which was weighted to help return the piston in the atmospheric cylinder during the dead stroke and overcome the dead centres of the crank. Wasborough's flywheel made the counterweight unnecessary, and engines were built with this and Pickard's crank. Several Birmingham business people seem to have been involved in the patent, and William Chapman of Newcastle upon Tyne was assigned the sole rights of erecting engines on the Wasborough-Pickard system in the counties of Northumberland, Durham and York. Wasborough was building engines in the south until his death the following year. The patentees tried to bargain with Boulton \& Watt to exchange the use of the crank for that of the separate condenser, but Boulton \& Watt would not agree, probably because James Watt claimed that one of his workers had stolen the idea of the crank and divulged it to Pickard. To avoid infringing Pickard's patent, Watt patented his sun-and-planet motion for his rotative engines.

  • 9 Richard of Wallingford, Abbot

    SUBJECT AREA: Horology
    [br]
    b. 1291/2 Wallingford, England
    d. 23 May 1336 St Albans, Hertfordshire, England
    [br]
    English cleric, mathematician and astronomer who produced the earliest mechanical clock of which there is detailed knowledge.
    [br]
    Richard, the son of a blacksmith, was adopted by the Prior of Wallingford when his father died and educated at Oxford. He then joined the monastery at St Albans and was ordained as a priest in 1317. After a further period at Oxford studying mathematics and astronomy he returned to St Albans as Abbot in 1327. Shortly after he had been elected Abbot he started work on a very elaborate astronomical clock. The escapement and the striking mechanism of this clock were unusual. The former was a variation on the verge escapement, and the hour striking (up to twenty-four) was controlled by a series of pins laid out in a helical pattern on a drum. However, timekeeping was of secondary importance as the main purpose of the clock was to show the motion of the Sun, Moon and planets (the details of the planet mechanism are lost) and to demonstrate eclipses. This was achieved in a very precise manner by a series of ingenious mechanisms, such as the elliptical wheel that was used to derive the variable motion of the sun.
    Richard died of leprosy, which he had contracted during a visit to obtain papal confirmation of his appointment, and the clock was completed after his death. The last recorded reference to it was made by John Leyland, shortly before the dissolution of the monasteries. It is now known only from incomplete manuscript copies of Richard's treatise. A modern reconstruction has been made based upon J.D.North's interpretation of the manuscript.
