Locks of every variety of principle and quality are produced in Willenhall; the chief kinds being the cabinet lock, the best qualities of which range from 10s. to £3 each, while the commoner ones are sold at from 10s. to 3s. the dozen; the rim lock for doors having two or three bolts, and opening with knob and key; the stock or fine plate lock, imbedded in a wooden case to stand the weather when used on exposed yard or stable doors; the drawback lock for hill doors, with a spring bolt that can be worked from the inside with a knob or from the outside with a latch-key; the dead lock, having one large bolt worked by the key, but not catching or springing like the rim lock; the mortice lock, which is buried in the door, and may be of the dead, the rim, or the drawback variety; the familiar loose padlock made in immense quantities both of iron and of brass; and others less familiar. The lock-producing centre includes Wolverhampton, Willenhall, Wednesfield, and some of the outlying rural districts like Brewood and Pendeford, where parts and fittings are prepared. In the mother parish the business is extensive and extending; at Wednesfield, iron cabinets and till locks, as well as various kinds of keys, are produced in great numbers, for keys are frequently made apart from the locks as a separate branch of the trade. Willenhall produces most of the same kinds as Wolverhampton, except the fine plate, though oftener in the cheaper qualities; rim locks are very largely made, all on the Carpenter and Young patent, most of them for export. Willenhall locks are all warded, the wards varying in strength and complexity, known as common, fine round, sash, and solid wards. It was the Carpenter and Young invention of 1830, making the action of the catch bolt perpendicular instead of horizontal, which renewed the vitality of the town’s staple industry. As registered the patent was entered:— “No. 5,880, 18 January, 1830. James Carpenter, of Willenhall, and John Young, of Wolverhampton, locksmiths. Improvements in locks.” Mr. R. B. Prosser, a recognised authority on patents and inventions, records that in 1841 Carpenter brought an action against one Smith, but the verdict was given for the defendant, it being held that Carpenter’s lock was not a new invention (Webster’s Reports of Patent Cases, Vol. I., p. 530). Notwithstanding this the lock has always been known, and is still known, as “Carpenter’s lift-up lock.”
