bric, and will consequently require no colour; these omissions can be easily made in their proper places along the party-coloured yarns, by setting out the pattern so that those parts of the yarns will be known when they are wound round the cylinder, and may be passed over without applying any colouring matter thereon. The places which are so left uncoloured in the yarns will be extremely useful as indications to the weaver of the places where the tufts are to loop and knot around the yarns of the warp.

Fig. 106 represents the cylinder A A in perspective, together with the rack B B containing the bobbins a a, from which the yarns b, are furnished to the cylinder A A as fast as they are wanted, when the latter is turned round in order to wind them around its circumference, as herein before mentioned. Figs. 112 and 113 also represent the cylinder, and the same letters of reference are used to denote the same parts in all the figures. CCEL Fig. 113, and KKL Figs. 114 and 115 is the wooden frame for supporting the axis D of the cylinder AA; EL (see Figs. 113 and 114) are upright standards to support a horizontal shelf or rest F, which is fixed across the width of the cylinder, and serves to place the rulers by which the colour is to be applied to the yarns, in a truly horizontal position, and so that each ruler will be presented to the cylinder A A at the same height thereon; dd, (see the Figures 107 and 109) is a guide screw, which is mounted horizontally in bearings notched out in each of the upright standards EL (see Fig. 113;) the screw d d, has a pulley e, fixed on the extreme end of it, in order to turn it round by means of an endless band or strap ƒ ƒ (see Fig. 112,) from another pulley g, which is fixed on the extreme end of the axis D of the large cylinder A A; wherefore, the screw dd, will be turned round with a motion corresponding to that wherewith the cylinder A A is turned; GG (see Fig. 107) is a conductor for the yarns, which is fitted on the guide screw d d, so as to be moved gradually along thereby across the width of the cylinder A A, when the latter is turned round. The rack or frame BB (Fig. 106) contains as many bobbins a a, as the number of yarns which it is intended to wind around the cylinder A A, for colouring at one operation.-A yarn b, from each of the several bobbins a a, is conducted beneath a fixed horizontal rod or wire h, then over another such rod or wire i, and beneath a third fixed rod or wire k; which three rods or wires, by opposing a slight friction to the yarn or yarns when drawn across the rods or wires, will cause the yarn or yarns to be extended with a proper tension when drawn afterwards by the cylinder A A. After passing under the third rod or wire k, each of the several

yarns is passed through a distinct eye in a wire guide z z, Figs. 106 and 107) which is fixed upon the top cross rail R of the conductor G G (see Figs. 106, 107, and 108) and, finally, each of the yarns is passed through a wire loop m, which is fixed in the top cross rail R (see Figs. 107 and 108) and projects so far out therefrom as to reach near to the circumference of the cylinder. (see Figs. 113 and 114) is a fixed rest or guide for the tails of the conductor G G to bear against, when the screw dd, is turned round, and as it carries the conductor G G literally across the width of the cylinder A A in the manner before stated, and in so moving it will guide each of the yarns, so that the successive coils which that yarn makes around the circumference of the cylinder will fall close to each other side by side; and, if that coiling is continued until the last coil made by one yarn joins up to the first coil made by the neighbouring yarn, then, the whole surface of the cylinder will be covered with the several yarns.-The conductor G G is made double, and fitted upon the screw dd, near to each end thereof, the two conductors G G being united by two wooden rails R S, and each part which is so fitted on the screw d d, is formed in two parts Gp, (see Figs. 107, 108, and 109) which are jointed together at q, in the manner of a pair of pincers, to grasp the screw d d, by the action of the spring r, which is interposed between the handles G p, of the two parts, in order to urge them apart from each other, and cause the other parts ss, of the pincers to grasp the screw dd between their jaws, by clasping the two handles Gp, of each of the conductors together in the hands, their spring r, can be overcome to open the two pincers, and then both the conductors G G become detached from the threads of the screw d d, in order to move the whole back from one end of the screw to the other, without the trouble and delay of turning the screw round backwards after one set of yarns has been wound round the cylinder, in order to prepare for winding on another set.*

Figs. 114 and 115 represent the cylinder as it appears when a part H H of its circumference is folded inwards towards the axis, in order to admit of taking off the yarn from it after it has been rendered party-coloured. Two portions H H of the circumference are

* A more simple guide or conductor for coiling the yarns on the cylinder A A, as represented in Figs. 106, 107 and 108, may be used; and as every manufacturer of cotton goods in Great Britain is well acquainted with the common traverse or spooling motion, no difficulty can be experienced by them on this head. We are confident that the manufacture of this kind of carpet, (the velvet pile) is destined ere long to receive vast improvements: indeed, we would not be at all surprised to see from 25 to 30 yards of it manufactured

attached to the remaining portion of the circumference by hinges in the manner of a pair of folding doors; also, a portion II of each of the rims and arms of the cylinder is attached to their central naves on the axis by hinges, so as to admit of folding those portions of the rims and arms down out of their proper places, and then the two portions H H of the circumference by dropping in towards the axis, will slacken and set the yarn free upon the cylinder, in order that they may be removed or doffed from off the same, in like manner as a common yarn real is doffed when it becomes covered with hanks of yarn. And, in order to admit of so doffing the yarns from the cylinder, the side K K L of the wooden frame (Fig. 114) which supports one end of the axis D, is made to turn down in the manner shown in Fig. 115, about hinges at its lowest part, by which hinges it is attached to one of the ground sills of the frame; and, when the side KKL is placed upright in a proper position to support the cylinder, as is shown in Fig. 113, it is retained by an oblique strut M, which is also attached by a hinge at its lowest end to the cross sill of the frame, so that it can be turned down out of the way in the manner shown in Fig. 115, when the side KKL of the frame is to be turned down.-Note, before that side is so turned down, the weight of the cylinder A A must be suspended as shown in Fig. 115, by a tackle of pulleys N, applied in an oblique direction between the arms of the cylinder from a support at the ceiling of the room, and reaching to the end of the axis D of the cylinder. The cylinder is framed with two sets of arms, upon the two ends of the axis, and two circular rims on those arms as shown on the drawings. The circumference is composed of boards fixed across the edges (as in the construction of card drums) of the two rims parallel to the axis of the cylinder, and the outside circumference being formed to a true cylinder, is covered with a printer's blanket strained tight and sewed.-A covering of oiled or varnished cloth is spread evenly over the blanket, and secured thereto by pins. The yarns are wound round the covering of oiled cloth in order to receive their colour, but the said oiled cloth cover is unpinned, and removed from the cylinder along with the yarns when they are doffed, in order to preserve them from blurring their colours by handling in doffing.
