The Evolution of a Goodyear Welt Shoe
1. A last. 2. An upper. 3. An Insole. 4. Shoe lasted and ready to have welt sewed on. 5. Welt partly sewed on. 6. Welt entirely sewed on the shoe. 7. An outsole. 8. Shoe with outsole laid and rounded; channel lip turned up ready to be stitched. 9. Shoe with sole stitched on. 10. Shoe with heel in place. 11. Heel trimmed and shoe ready for finishing.
The remaining machines have to do with the final finishing. They include trimmers, stitch separators, edge setters, buffers, finishers, cleaners, stampers, shoe treers, creasers, etc., each playing a part of some importance in giving a final finish to the shoe and making it presentable to the wearer. The whole operation, as will be seen, is a highly complicated one, and is remarkably effective in preparing an article that shall appeal to the salesman and purchaser and prove satisfactory when put into use.
Such is the complicated process of making a shoe by machinery. It would be hard to find any machine process that surpasses it in complexity and the number of separate machines involved. Poor old St. Crispin would certainly expire with envy if he could see his favorite thus taken out of the hands of his artisans and the shoe whirled rapidly through a host of odd but effective contrivances on the way to become made fit for wear.
What is “Standard Gold”?
Gold is one of the heaviest of the metals, and not being liable to be injured by exposure to the air, it is well fitted to be used as coin. Its ductility and malleability are very remarkable. It may be beaten into leaves so exceedingly thin that one grain in weight will cover fifty-six square inches, such leaves having the thickness of only 1⁄282000th part of an inch. It is also extremely ductile; a single grain may be drawn into a wire 500 feet long, and an ounce of gold covering a silver wire is capable of being extended upwards of 1,300 miles. It may also be melted and remelted with scarcely any diminution of its quantity. It is soluble in nitromuriatic acid and in a solution of chlorine. Its specific gravity is 19.3, so that it is about nineteen times heavier than water. The fineness of gold is estimated by carats, pure gold being twenty-four carats fine.
Jeweler’s gold is usually a mixture of gold and copper in the proportions of three-fourths of pure gold with one-fourth of copper. Gold is seldom used for any purpose in a state of perfect purity on account of its softness, but is combined with some other metal to render it harder. Standard gold, or the alloy used for the gold coinage of Britain, consists of twenty-two parts of gold and two of copper (being thus twenty-two carats fine).
