.Patent granted to JoHn Cowr~ERoY, .[or manufacturing Bread and Biscuits. Dated Oelober 14, 1831. This invention is to make bread on a large scale, or to prepare in a shorter time a greater qua.tity of loaves than manual labour can produce. There is a wooden vessel, tub, or trough, in which is first prepared the liquid matters which form so large a portion of our bread loaves. What these are, Mr. Accum has tom us we ought not particularly to inquire into, if we woohl' eat heartily. ~ot setting aside all thoughts of dried bones pounded, alum, yest, potatoes, salt, water, &c. we will'suppose the liquor prepared in this wooden vat, or trough. It has a large wooden cock near the bottom, which being open, its contents are issued into an inclined pipe, or channel, or conductor to the kneeding trough. Over this c[~annel is a floor box duly prepared, attached to which is a drum, or, cylindei', 'begirt with rows of brushes, or bristles, to temse or cleanse the flour, forcing it in equal quantities through a wire sieve, so as to make it mix equally', gradually, and completely with the liquor, in order to make a sponge in the kneading trough; it is then allowed to rise, and.when the ingredients are added which are necessary to complete its doughy character, it is removed on a long rail-way to a part of the bread mannfactory, in which is situated a large frame with a variety of moulds of ditl~rent sizes and shapes. When the dough is thus made into loaves, or moulded into the prescribed form, it sets off on another rail-way journey, anti is conducted safely into the oven i n the way" most conducive to its easy anti speedy baking. When that time comes, the other end of the oven is opened, and an immense featheredged peel, which moves on wheels, is introduced, and the huge baking is removed in large quantities, and at few batches, from the oven. The process is equally applicable to the production of biscuits, and the whole invention1 would have been attributed in ancient days to the direct influence and inspiration of the much worshipped deity Jupiter Pistor. What a grand accorr,paniment to the commissariat department of an army, or to the provant stores of a besieged garrison ! [Rep. Pat. Inv.

The tin plates are polished by heitjg passed through between the rotlers previously to their being formed into ladles, spoons, or other articles of culinary use. In stamping the polished plates into tile forms for which they are intended, dies of the usual form, but of much finer finish, so as not to injure the polish of the plates, are to be employed. Tile articles are theutobe finished in tile manner usually adopted in completing the manufac. ture of spoons, ladies, and other culinary utensils.

Patent granted to Monsieur LE PETIT LAMASURE,Jr.,Founder, at Rouen, and proprieior of the Forges in the Deparl/ne~'~tof Lot-et.Ga. ronne; for a double case.furnace Tewel, supphed with waler, and a moveable tube within, to regulate the current of air,.for the purpose of economising the combustible and the workmanship; also to obtain a [greater proportion of iron. General observations upon thejneonveniences of ordinary Tewels,and of their position. The most experienced manufacturers of iron have agreed that the inclination, more or less, in the placing of the tewel, is sufficient for obtaining a fourth, and sometimes even a third, less of the ore, than is procured when the same tewel, by its position, forms a strict angle agreeing with the vertical line that passes by the axis of the fi~rnace. But supposing that it be easy and convenient to place this tewel, so that tile current of air be introduced into the furnace with every re. quisite advantage, we must admit that it will suffer no derangement or descension during the whole course of the operation, which we cannot allow~ tbr upon this point, and up to the i~resent moment, an imperfection has existed which involves the inevitable causes of the loss occasioned by these said tewels. It] fact, after having bestowed much time and pains in the construction of a furnace, Wherein scrupulous attention has been observed in properly disposing a tewel of tile ordinary form and manufacture, it is no unusual occurrence !o find it insensibly altering, and the mouth of the air-pip.e changed in figure, and augmented--and this at every instant: a serJous mconve. mence, oecause tl~e same quantity of air issuing by two orifices of diflhrent dimensions, and propelled by the same force (their reiative speed .being an inyerse ratio to the orifices,) it follows that if the prlmmve ortiice give vent to proper swiftness, and in a convenient n~rectton, it is ce,'tain that the one which manifests deterioration wilt not fulfil the same functions: thence follows the necessity of repine*
