In 1878 Mr. Edmund Wiseman (who is still living), of Luton, took out a patent for a machine to sew plaits with a “concealed” stitch. In 1880 some improvements were made, and for some years the “Wiseman Concealed Stitch” machine sold at about half the price of the “Légat,” and by no means as intricate and delicate, gradually displaced the French machine. Between 1880 and 1886, Mr. Bland, of Luton, and Mr. William Walker of Dunstable, both patented concealed stitch machines, but without much success. In 1886 Mr. Wiseman entered into arrangements with the Willcox & Gibbs Co. to produce an improved concealed stitch machine that from its shape and method of action was called the “Box machine.” This, although on the same lines as the first invention with regard to the method of stitch and sewing, was capable of sewing all kinds of plait both fine and coarse, whereas the earlier patent was only really successful on fine plaits. This Box machine has been greatly improved since 1886, but taken on the whole, its general characteristics are the same. In 1895 Messrs. Janes Bros., of Luton, took out a patent for a concealed stitch machine called the “Lutonia,” which has met with a very distinct success. Meanwhile the demand for hats of certain plaits, which were improved by the outside stitch sewing, kept on increasing, and indeed there are plaits on which even the so called “visible” stitches are _invisible_. Plaits of cotton, silk, ajour, and crinoline are of such nature that the cotton used in the outside stitch machine sewing seems to lose or bury itself in the material of the braid, and there is less likelihood of the needle catching in their tough fibres than there is in the working of the Box machine, where a hook is used; and further for some years plaits of fine chip were the dominant demand, and for these there was less tendency on the part of the fine single needle of the visible stitch machine to cut the narrow wood strands, than if the double punctuation of the Box machine needle and hook were used. In 1879, therefore, the Willcox & Gibbs Co. took out a patent for what is now known as the “17 Guinea” type of visible stitch sewing machines. This model has been closely followed by the “Dresdensia,” a German product of signal value; and “The Singer,” an American competitor, both of which are in the main imitations or copies of the 1879 patent. It is a fact worthy of note that the first successful machine to sew a hat of straw plait from button to circumference of brim was a Willcox & Gibbs, and that the latest word in straw sewing is also, by the arrangement with Mr. Wiseman, a product of the same firm.
