warmest friends. The Countess of Ellesmere continued the friendship until her death, which occurred several years later. The same kindly feelings still exist in the children of the lamented pair, all of whom evince the admirable qualities which so peculiarly distinguished their parents, and made them universally beloved by all classes, rich and poor.] I must here say a few words as to my Screw Safety Ladle. I had observed the great danger occasioned to workmen by the method of emptying the molten iron into the casting moulds. The white-hot fluid was run from the melting furnace into a large ladle with one or two cross handles and levers, worked by a dozen or fifteen men. The ladle contained many tons of molten iron, and was transferred by a crane to the moulds. To do this required the greatest caution and steadiness. If a stumble took place, and the ladle was in the slightest degree upset, there was a splash of hot metal on the floor, which, in the recoil, flew against the men's clothes, set them on fire, or occasioned frightful scalds and burns. To prevent these accidents I invented my Safety Foundry Ladle. I applied a screw wheel, keyed to the trunnion of the ladle, which was acted on by an endless screw attached to the sling of the ladle; and by this means one man could move the largest ladle on its axis, and pour out its molten contents with the most perfect ease and safety. Not only was all risk of accident thus removed, but the perfection of the casting was secured by the steady continuous flow of the white-hot metal into the mould. The nervous anxiety and confusion that usually attended the pouring of the metal required for the larger class of castings was thus entirely avoided. At the same time I introduced another improvement in connection with these foundry ladles which, although of minor importance, has in no small degree contributed to the perfection of large castings. This consisted in hanging "the skimmer" to the edge of the ladle, so as to keep back the scorae that invariably float on the surface of the melted metal. This was formerly done by hand, and many accidents were the consequence. But now the clear flow of pure metal into the moulds was secured, while the scoriae were mechanically held back. All that the attendant has to do is to regulate the inclination of the Skimmer so as to keep its lower edge sufficiently under the surface of the outflowing metal. The preceding illustrations will enable the reader to understand these simple but important technical improvements. These inventions were made in 1838. I might have patented them, but preferred to make them over to the public. I sent drawings and descriptions of the Safety Foundry Ladle to all the principal founders both at home and abroad; and I was soon after much gratified by their cordial expression of its practical value. The ladle is now universally adopted. The Society of Arts of Scotland, to whom I sent drawings and descriptions, did me the honour to present me with their large silver medal in acknowledgment of the invention. In order to carry on my business with effectiveness it was necessary that I should have some special personal assistance. I could carry on the whole "mechanical" department as regards organisation, designing, and construction; but there was the "financial" business to be attended to, -- the counting-house, the correspondence, and the arrangement of money affairs. I wanted some help with respect to these outer matters. When I proceeded to take my plot of land at Patricroft some of my friends thought it a very bold stroke, especially for a young man who had been only about three years in business. Nevertheless, there were others who watched my progress with special interest, and were willing to join in my adventure -- though adventure it was not. They were ready to take a financial interest in my affairs. They did me the compliment of thinking me a good investment, by offering to place their capital in my concern as sleeping partners. But I was already beyond the "sleeping partner" state of affairs. Whoever joined me must work as energetically as I did, and must give the faculties of his mind to the prosperity of the concern. I communicated the offers I had received to my highly judicious friend Edward Lloyd. He was always willing to advise me, though I took care never to encroach upon his kindness. He concurred with my views, and advised me |
