Machinery for Finishing Sash-bars, Ridge-Pieces, and Gutters Text from The Illustrated London News

We have already (at page 401) described the machinery by which the sash-bars, skylight-bare, and ridge-pieces for the skylights are cut out of nine-inch planks, by machinery, at the Phoenix Saw-Mills, near the Regent’s Park. We now proceed to show the further progress of a sash-bar to its completion, which is effected at the works of the Great Exhibition, a representation of which is given on the present page. In order, however, to present our readers with a clear view of the interesting machinery employed for the purpose, we must first mention the power employed to give motion to such machinery. As in every other part of the works the utmost skill is displayed with regard to economising power, so in the disposition of the machinery in connexion with the steam-power employed, and which we are about to describe, considerable ingenuity is visible throughout. The engine, calculated at eight horse-power (equal to the collective force of forty-four men), is on the locomotive principle, working with steam at a pressure of 60 lb. to the square inch. The boiler (placed east and west) is furnished with twenty-seven 2-inch copper tubes, placed horizontally, coke being the fuel chiefly used.
