Many thanks to José Ignacio Aguilera Martinez for the following information. José states – I share some images of the exhibition room that I developed, about the mining history of the nineteenth century in La Higuera (Chile). In it, there are photographs of reverberatory furnaces and a series of refractory bricks, of the group the only Chilean…

No 7253 – George Marquis of Tweeddale. Forming drain tiles by passing the clay from the feeding hopper between two horizontal cylinders on to an endless web, which passes over a shaping cylinder, turned out in the middle to the form of a drain tile ; after which the tile is completed by passing between a pair of inclined rollers and a second shaping cylinder, and is carried by two narrow endless bands beneath a cutting wire, and thence by an endless web to the drying shed.
Making flats or soles by passing the clay between the horizontal cylinders on to an endless band, by which it is carried to the cutting wires.
Flat roofing tiles of equal thickness throughout are made in like manner; but if required to be thin at the upper or nail end, or to have a flat knob or prominence on the end, the upper horizontal cylinder must be suitably shaped. A nail-hole is made in each tile by a punch attached to a lever. An instrument for placing flat tiles on the drying shelves instead of the common peal.
Bricks are produced by modifying the machinery used in manufacturing flat tiles.
House tiles are formed by a pair of moulds, the upper worked by a lever or crank, and the lower capable of sliding on a rod out of its frame to deliver the tile.
The clay is prepared by passing between a pair of large crushing cylinders and is then milled in the usual way.
01/08/1838 – Patents for inventions. Abridgements of specifications. No 7757 – Tweeddale, George Marquis of. — The invention forming the subject of these Letters Patent is the same as N° 7253.

Many brick and tile works were instigated by improving estate owners – George Hay, 8th Marquis of Tweeddale, obtained a patent for innovative tilemaking equipment in 1839. In general, these rural works were small scale.
Marquis of Tweeddale is mentioned in Newton’s London Journal of Arts and Sciences dated 1843 – page 369 – 70.
Field Marshal George Hay, 8th Marquess of Tweeddale, KT, GCB (1 February 1787 – 10 October 1876) was a Scottish soldier and administrator. He served as a staff officer in the Peninsular War under Arthur Wellesley and was with Wellesley at the Second Battle of Porto when they crossed the Douro river and routed Marshal Soult’s French troops in Porto. Hay also saw action at the Battle of Bussaco and at the Battle of Vitoria. He later served in the War of 1812 and commanded the 100th Regiment of Foot at the Battle of Chippawa when he was taken prisoner of war. He went on to become Governor of Madras and, at the same time, Commander-in-Chief of the Madras Army, in which role he restored the discipline of the army, which had been allowed to fall into a relaxed state.
