Inventor: IMRAY OLIVER
Filed: 1901-07-15
Granted: 1902-06-19
Abstract: 14,390. Imray, O., [Fabriques de Produits Chimiques de Thann & de Mulhouse]. July 15. o-Toluene sulphochloride is produced from a mixture of o- and p-toluene sulphonic acids by the following process. After precipitating the p-sulphonic acid from the original mixture by treatment with cold water or ice and maintaining a low temperature, the solution is diluted with a small quantity of water, and allowed to rest at about 5‹ below zero C. for at least 48 hours, whereby the o-toluene-sulphonic acid is separated. The crystals, which retain a little sulphuric acid, are dissolved in water, the sulphuric acid is precipitated by sufficient lime, and the filtrate, containing pure o-toluene-sulphonic acid, is saturated with a suitable metallic salt, preferably magnesium carbonate, and evaporated to dryness at 110‹-120‹ C. The powdered magnesium sulphonate is then added to chlorosulphonic acid (S03HCl) whilst stirring and cooling to 15‹ to 18‹ C. After a few hours the pure o-toluene sulphochloride produced is precipitated by pouring the mixture on ice.

Title: Improvements in the Manufacture of Azo Colouring Matters and Intermediate Products relating thereto
Inventor: JOHNSON JAMES YATE
Filed: 1901-10-14
Granted: 1902-07-17
Abstract: 20,551. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Oct. 14. 1 : 2 : 4-Trichlor-3-nitrobenzene-5-sulphonic acid is produced by sulphonating 1 : 2 : 4-trichlorbenzene, for example, by treatment with fuming sulphuric acid containing 23 per cent. of SO3, at a temperature not exceeding 50‹ C., and then nitrating the product by adding nitration acid. The mixture is poured upon ice, and the sodium salt of the new product is precipitated by common salt. 1 : 2 : 4-Trichlor-3-amidobenzene-5-sulphonic acid results when the foregoing nitro-compound is reduced by means of iron and acetic acid. It is obtained in crystalline form, by precipitating iron and acidifying the filtrate with hydrochloric acid. Dyes, artificial.-Compounds which are believed to be diazophenol derivatives are produced by acting upon the diazo compounds of the foregoing trichloraniline sulphonic acid, and upon o-nitraniline-p-sulphonic acid and 2 : 4-dinitraniline, with a compound which will bind hydrochloric acid, such as sodium acetate, sodium or potassium carbonate or bicarbonate, sodium oxalate, magnesia and the like, in suitable proportions. The process may be varied by diazotizing the parent substance with sodium nitrite and an organic acid, such as oxalic or acetic acid, whereupon diazotization and transformation into the diazophenol derivative are simultaneously effected. Another modification consists in converting the diazo derivatives of the amido compounds into the corresponding nitrosamine derivatives, as described in Specifications No. 20,605, A.D. 1893, and No. 3397, A.D. 1894, and then acidifying these products with an organic acid. The diazophenol derivatives above mentioned combine with the usual orange, red, brown, and violet ato dye-stuff components to form dyes which, when treated on the fibre with chromates, copper salts, or the like, change their shades and become faster against washing, light, and other influences. Such dyes are produced by the combination of the diazophenol derivatives with #-naphthol, resorcin, m-hydroxydiphenylamine, 1 : 8-amidonaphthol-4- sulphonic acid, 1 : 5- and 2 : 5-amidonaphthol-7- sulphonic acid, 2 : 8-amidonaphthol-6-sulphonic acid, 2-naphthol-3 : 6-disulphonic acid (R), mphenylenediamine, m-toluylenediamine, 1-naphthol- 4 - sulphonic acid, naphthionic acid, alpha - and #-naphtholcarboxylic acid, 2 : 7-dihydroxynaphthalene, and phenyl - methylpyrazolone, and particulars with regard to their properties are given in the Specification.

Title: Improvements relating to Machines for Sewing Boots and Shoes.
Filed: 1901-12-30
Granted: 1902-07-03
Abstract: 26,601. Lake, H. H., [Duplessis Pegging and Sewing Machine Co.]. Dec. 30. Boot - sole stitching- machines; chain-stitching machines; governing needle thread.- Relates to a machine employing a circular hooked needle and consists of improved take-up and threadfeed devices, and of improvements connected with the needleguide. On its way to the needle the thread is wound round a double ratchet -wheel 67 having two sets of teeth pointing i n opposite directions. A pawl engaging one set of teeth always prevents backward rotation, while a spring- pressed pawl 74, pivoted at 78, engages the other teeth during the take-up only. A lever 77, pivoted at 78 and engaging the pawl 74, has a projection 83 on which the end 84 of a cam-actuated lever 86 normally rests in order to hold the pawl 74 away from the ratchet-wheel. Between the ratchet-wheel 67 and the thread tube 61 the thread passes over a fork 97 carried by the lever 86, and the take-up is effected by the movement of the lever 86 and fork 97 to the position shown, the pawl 74 being thus at the same time allowed to engage the ratchet-wheel 67 and lock the thread. The thread-feed fork 107 engaging the thread between the ratchet-wheel 67 and the tension 54, is carried on the end of the needleactuating lever 101. Between the tension and the fork 107, the thread passes over a stud 109 on a lever 108 connected by a link 110 to the presserbar 19, so that the amount of thread pulled off is proportioned to the thickness of the work. Means are provided, actuated by turning the machine backwards, for relaxing the tension 54, in order, for instance, to take the work off the machine. An elbow lever 119, 59, adapted to engage the tension spring, is connected by a chain to a lever 113 normally held in inoperative position by a spring 117 and stop 116. On the upper end of the lever 113 is pivoted a lever 120 having spring-cushioned jaws engaging the lever 113. When the shaft 5 runs forward (in the direction of the arrow), the lever 120 is merely vibrated by the stud 125, but, when it is turned back, the stud 125 engages the face 124 of the lever 120, and operates the levers 113 and 119, 59 to relax the tension. Needle shields; needle-driving.-The needle-guide 22, Figs. 2 and 9, is mounted loosely on a brush 29 fixed in the frame, and is connected by a pin 28 to a shaft 31 having its bearings in the bush 29, and fitted, on its squared end 36 with an arm 38. The needle-guide is retained in its advanced position, determined by a stop 43<a>, by a spring connected to the arm 38. A fine adjustment of the advanced position of the needle-guide is obtained by a pivoted cam-plate against which the arm 38 can engage. The needle-carrier 23 moves in a circular race formed by the block 24 and plate 25.
