with his feet a series of operations no less delicate than those which he executes with hishands.

The pedals p are moveable round the axis p, and carry cords p' wound in an oppositedirection upon the pulleys p' ; these pulleys are fixed upon a moveable shaft p", sup-ported upon one side by the prop e', and on the other in a piece k' attached to the twogreat uprights of the frame. In depressing the pedal p (now raised in the figure), theu Pper part of the shaft p" will turn from the left to the right, and the lever n o will be-c ome inclined so as to carry the wheel o' upon the wheel m', but at the same time thePedal which is now depressed will be raised, because its cord will be forced to wind itselfu Pon its pulley, as much as the other cord has unwound itself; and thus the apparatusWill be ready to act in the opposite direction, when wanted.

Disposition of the pincers. —The shaft I.' carries, at regular intervals of a semi-diame-fer, the appendages q q cast upon it, upon which are fixed, by two bolts, the curvedbranches ft destined to bear the whole mechanism of the pincers. When the pincers areopened by their appropriate leverage, and the half of the needle, which is pointed ateac b end, with the eye in the middle, enters the opening of its plate, it gets lodged in anajlgular groove, which is less deep than the needle is thick, so that when the pincers arecl °sed, the upper jaw presses it into the groove. In this way the needle is firmly held,although touched in only three points of its circumference.

Suppose, now, that all the pincers are mounted and adjusted at their proper distancesupon their prismatic bar, forming the upper range of the nr lit carriage. For opening all

le pincers there is a long plate of iron, V, capable of turning upon its axis, and whichExtends from the one end of the carriage to the other. This axis is carried by a kind of■ ° r ks which are bolted to the extremity of the branches ft. By turning that axis the*urlcman can open the pincers at pleasure, and they are again closed by springs. This

Wernent is performed by his feet acting upon the pedals.

, Ihe threads get stretched in proportion as the carriage is run out, but as this tension

s b° elastic play, inconveniences might ensue which are prevented by adapting to thea rria ge a mechanism by means of which all the threads are pressed at the same time bytb' Ve ‘."b t susceptible of graduation. A little beneath the prismatic bar, which carriesoth *” ncers > we see in the figure a shaft, y, going from one end of the carriage to thea ® r > ar| d even a little beyond it; this shaft is carried by pieces y which are fixed to thea( . s and in which it can turn. At. its left end it carries two small bars y' and w', andHie f S ri =^ t a single bar y', and a counterweight (not visible in this view) ; the ends ofthe tW ° •* >ars y are joined by an iron wire somewhat stout and perfectly straight. Whenpr es carr i a ge approaches the web, and before the iron wire can touch it, the little bar w\ v l 8e s a gainst a pin, w', which rests upon it, and tends to raise it more and more. Inb(, t , a as preceded we have kept in view only the upper range of pincers and needles,a is an inferior range quite similar, as the figure shows, at the lower ends of the
