The planing machine, the milling machine and the shaping machine were developed in the early decades of the 19th century. Although the milling machine was invented at this time, it was not developed as a serious workshop tool until somewhat later in the 19th century.
There have been other times that have been called "second industrial revolution". Industrial revolutions may be renumbered by taking earlier developments, such as the rise of medieval technology in the 12th century, [108] or of ancient Chinese technology during the Tang dynasty, or of ancient Roman technology, as first.
11th century - Sets of hourglasses were maintained by ship's pages to mark the progress of a ship during its voyage; 11th century - Large town clocks were used in Europe to display local time, maintained by hand; 1335 - First known mechanical clock, in Milan; 1502 - Peter Henlein builds the first pocketwatch
The hourglass, invented in Europe, was one of the few reliable methods of measuring time at sea. In medieval Europe, purely mechanical clocks were developed after the invention of the bell-striking alarm, used to signal the correct time to ring monastic bells.
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

To Babbage's delight, the Scheutzes completed the first full-scale difference engine, which they called a Tabulating Machine. It operated on 15-digit numbers and 4th-order differences, and produced printed output just as Babbage's would have. A second machine was later built in 1859 to the same design by the firm of Bryan Donkin of London. 1856
Like the typewriter, these machines were products of the second phase of the Industrial Revolution which started near the end of the 19th century (also called the Second Industrial Revolution). [1] This second phase brought to mass markets technologies like the small electric motors and the products of industrial chemistry without which the ...
The hand axe is the first example of a wedge, the oldest of the six classic simple machines, from which most machines are based. The second oldest simple machine was the inclined plane (ramp), [6] which has been used since prehistoric times to move heavy objects. [7] [8] The other four simple machines were invented in the ancient Near East. [9]
