306 of Alexander Brodie, Eſq.[Dec.
chimney-ſweeper, when in the chimney, by ſhutting the Regiſter- door, prevents any part of the ſoot from falling into-the room. In ſummer, the regfler may be kept ſhut ſo as to exclude rain, hail,&c. while an air-courſe is kept open by a valve at the bottom of the Regiſter. The Regiſter is very eaſily regulated: in cold weather the handle needs only to be turned till the ſmoke begins to return, at which point the Regiſter-bandle muſt be turned one degree in an oppoſite direCtion, to remain ſo. If the room betoo hot, by raiſing the Regiſter as high as it will go, the circulation is rendered as great as 1f no ſtove were there.
In November, 1779, Mr. BRODIE put up a Regiſter-Stove m the fſtate-room at Windſor, where her Majeſty's celebrated needle-work is to be ſeen.“Mr. BRODIE, during this, took an opportunity of preſenting to his Majeſty's attention a model of a ſhip's hearth. Sir Alexander Hamilton had ordered one of theſé hearths for the ſhip the Laſcelles, Eaſt-Indiaman. His Ma- JESTY was pleaſed to command Mr. BRODIE to preſent it to the Navy BoARD, which he did, accompanied by Sir Alex= ander Hamilton, and Mr. Wells, a diſtinguiſhed builder. There were ſome objections, which were groundleſs, made againſt the ſhip’s hearth at the Naoy Board. Mr. B. received an order for two; the one to be put in the Fortitude, of 74 guns, and the other in ¿he Minerva, of g8- guns. The trial com- pletely eſtabliſhed the ſuperiority of Mr. BRoD1FE's ſhip's hearth to thoſe in general uſe; and Commodore FIELDING's teſtimony, of the great benefit he received in the Minerva, by iron boilers in eE to copper boilers, was much to Mr. BROD1E?s credit. The old hearths were fixed with brick, ſtone, mortar;&c. which require ſeveral different mechanics to fix them: Mr. BRoDIE's hearth has neither brick, mortar, nor ſtone, but is made of wrought-iron, well fortified with ſtrong plates of caſt- Iron; is eaſily fitted up, and requires little or no repairing; is- ſeven tons lighter than former hearths, and takes up but one- fifth of the room. Mr. BRoDIE has much improved diſtillery and baking by his hearths. He, and other authors of inventions like theſe, are the beſt benefa@tors to mankind. Their abbre- viations of labour'are the ſources of augmented-wages to the la- bourer; and the new accommodations which‘ they provide, tend to improve the general comforts of human life. f
In 1786, Mr. B. purchaſed the CarcurT mines, ſtock, houſes, &c. near. BROSELEY: from which government receives large ſupplies of cannon, and the country in geyeral, iron of the firſt quality. Mr. BRoD1% may juſtly boaſt of poſſeſſing one of the moſt ccmplete boring machines for cannon mm Europe.|
His attive mind induced him to hold a conſiderable ſhare in an iron-fóundery at MANCHESTER: and feeling a ſtrong predi- leétion for his native ſo1l, he eſtabliſhed, in 1792, an exten- ſive woollen manufadttory, in the paruh of INVERLEITII, oppo-
te to Lord Traquaire's, At Peebles, in Scotland, he has pur.
