As this dress will often be alluded to in the pages to follow, it may be well at this time to give its description: It was invented by C. S. Merriman of Iowa, and consists of a pants and tunic made of highly vulcanized rubber. When the pants are put on the tunic is pulled over the head and down over a steel band at the upper part of the pants where it is firmly secured by a rubber strap.
You want one quart of gin; I comprehend. Shall it be your Hollands, your Aromatic Scheidam, your Nantz, or our own proud Columbian article? You want one quart of rum, potus e saccharo confectus! You want one quart of brandy. You want one gallon of wine. You want a dozen of brown-stout. You want the patent vulcanized India-rubber pump. You want anise, pimpinella anisum; I comprehend.
In his laboratory note-books are innumerable jottings of the things that were carbonized and tried, such as tissue-paper, soft paper, all kinds of cardboards, drawing-paper of all grades, paper saturated with tar, all kinds of threads, fish-line, threads rubbed with tarred lampblack, fine threads plaited together in strands, cotton soaked in boiling tar, lamp-wick, twine, tar and lampblack mixed with a proportion of lime, vulcanized fibre, celluloid, boxwood, cocoanut hair and shell, spruce, hickory, baywood, cedar and maple shavings, rosewood, punk, cork, bagging, flax, and a host of other things.
The square threads from which elastic webbing is made may be cut from these sheets, though sometimes the sheet is wound on an iron drum, vulcanized by being put into hot water, lightly varnished with shellac to stiffen it, then wound on a wooden cylinder, and cut into square threads. Boiling these in caustic soda removes the shellac. To make round threads, softened rubber is forced through a die.
The juice is milk-white, thick, and glutinous, soon stiffening, darkening, and hardening without aid of art. I should like to see the raw material tried for making waterproofs in the tropics, where the best vulcanized articles never last. The Ndambo tree has been traced a hundred miles inland from the Liberian Coast; that of the Gallinas and Sherbro is the best; at St.
The great manufactories of vulcanized India-rubber in England, Scotland, France, and Germany are the result of his labors; but the peculiarities of the patent laws of those countries, or else his own want of skill in contending for his rights, prevented him from reaping the reward of his labors. He spent six laborious years abroad.
It lasts but two days, but it steals to-morrow's bread, the week's soup, the wife's dress, the child's wretched rags. Men, born doubtless to be beautiful for all creatures have a relative beauty are enrolled from their childhood beneath the yoke of force, beneath the rule of the hammer, the chisel, the loom, and have been promptly vulcanized.
Goodyear triumphantly vulcanized rubber in 1844, making serviceable a gum which had been used in various forms already but without ability to stand heat. Elias Howe took out his first patent for a sewing machine in 1846, being kept in vigorous fight against infringements for the next eight years. The anaesthetic power of ether was discovered in 1844. Gutta-percha was first imported hither in 1847.
Next he drew on a pair of rubber gloves with vulcanized rubber finger tips, and moistening with his lips the ends of the two platinum wires, pressed them to either side of the ball, first the one and then the other. A spark was given off when the second contact was made, and the room was filled with a pungent odour as of overheated metal which caused both men to cough violently.
He would have them look at the man whose cause he pleaded: a man of fifty-two, who looked fifteen years older, sallow, emaciated from disease, due to long privations, bitter disappointments, and wrongs. This was Charles Goodyear, inventor of the process which put rubber into the service of the world. Said Webster: "And now is Charles Goodyear the discoverer of this invention of vulcanized rubber?
