1913 'Pottery Trades Requirements Exhibition ..... Messrs. Hartley, Causton and Richmond, Ltd., constructional engineers, ironfounders, and boilermakers, Stoke, are exhibiting their patent flat knocking and flint sifting machine, by which the ware from an oven is handled under the influence of an efficient fan draught, during the most dangerous (to the workman) process that it has to undergo at this stage of manufacture. The saggar is placed straight from the oven immediately under an air exhaust opening, which draws away any flint dust raised as the saggar is emptied. The flat ware is placed on shelves situated conveniently for the operator, who places them in the knocker, the flint falling from the ware in to a sifter and thence into an ark. The flint left in the saggar is then emptied into a hopper, and also passes through a sifter into the same ark and is ready to he used again. The machine is so designed that one operator can knock the flat as fast as it is drawn from the oven. when the usual proportion of flat hollow-ware has been fired. All the operations are performed close to suitably situated exhaust openings, and additional openings are provided about on a level with the head of the operator. to catch any flint dust which may be missed by the other openings.'[2]
