took practical lessons in turning from a toymaker. After some time, thus diligently occupied, he returned to Alsace, to superintend the construction of the machinery for the new factory at Vieux-Thann, which was shortly finished and set to work. The operations of the manufactory were, however, seriously affected by a commercial crisis which occurred, and it passed into other hands, on which Heilmann returned to his family at Mulhouse.
He had in the mean time been occupying much of his leisure with inventions, more particularly in connexion with the weaving of cotton and the preparation of the staple for spinning. One of his earliest contrivances was an embroidering-machine, in which twenty needles were employed, working simultaneously; and he succeeded in accomplishing his object after about six months' labour. For this invention, which he exhibited at the Exposition of 1834, he received a gold medal, and was decorated with the Legion of Honour. Other inventions quickly followed—an improved loom, a machine for measuring and folding fabrics, an improvement of the "bobbin- and fly-frames" of the English spinners, and a weft winding-machine, with various improvements in the machinery for preparing, spinning, and weaving silk and cotton. One of his most ingenious contrivances was his loom for weaving simultaneously two pieces of velvet or other piled fabric, united by the pile common to both, with a knife and traversing apparatus for separating the two fabrics when woven. But by far the most beautiful and ingenious of his inventions was the combing-machine, the history of which we now proceed shortly to describe.
