round which it passes, and thence back to the tin roller, and thus, when the tin roller 

 receives motion from the rim band, it gives motion to the spindles. The carriage is 

 caused to move outwards by means of the cord L, one end of which is attached to 

 a ratchet pulley fixed on the carriage cross, or square L J , and is then passed over the 

 spiral grooved pulley i? fast on the drawing out shaft G, and passes thence under 

 the guide pulley L 3 round the pulley L 4 to another ratchet pulley, also on the carriage 

 square where the other end is then fastened. The cord receives motion from the 

 pulley L 2 , round which it passes and communicates the motion it receives to the car- 

 riage, the carriage-wheels i 1 moving freely on the slips b-. 



When the carriage has completed its outward run, the bowl a 4 on the counter 

 fallor shaft comes against the piece a 3 , depresses it and the end of the lever K. 3 to 

 which it is attached, and raises the other end, and with it the slide c, on which aro 

 two inclines. A round pin (not seen) passes through the boss of the catch-box next to the 

 slide, and bears against the sliding half of the cateh-box, and holds it out of contact. 



When the slide c is raised, the part of the incline which bore against the pin and 

 kept the catch-box from being in contact is withdrawn, on which the spring puts 

 them in contact, and motion is given to the hollow shaft, and the cams thereon ; one 

 of which causes the catch-box M to be taken out of contact when motion ceases to 

 be given to the drawing rollers and to the going-out of the carriage ; and the other 

 causes the driving strap to be traversed off from the fast pulley on to the loose one, 

 when motion ceases to be given to the rim pulley and thence to the spindles. The 

 inclines on the slide are so formed that, by the time the shaft has made half a revo- 

 lution, they act on the pin and cause it to put the catch-box out of contact. The 

 next operation is the backing-off or uncoiling the threads coiled on the spindle above 

 the cop, which is effected by causing the backing-off cones attached to the wheel J 8 to 

 be put into contact with one formed in the interior of the fast pulley F, when a reverse 

 motion will be given to the rim pulley and thence to the tin roller and the spindles. 



The backing-off cones are put into contact by means of a spiral spring, which, when 

 the strap fork is moved to traverse the strap on to the loose pulley, it is allowed to 

 do. Simultaneously with the backing-off the putting-down of the faller wire takes 

 place, which is effected through the reverse motion of the tin roller shaft, which 

 causes the catch c 1 to take into a tooth of the ratchet wheel c 2 , when they will move 

 together, and with them the plate c 3 , to a stud in which one end of the chain c 4 is 

 fastened, the other end of which is attached to the outer end of the finger c 5 , fast on 

 the faller shaft. When this chain is drawn forward by the plate, it draws down the 

 end of the figure c 5 to which it is attached, and thereby partially turns the faller shaft 

 and depresses the faller wire b 3 , and, at the same time, raises the lever c 5 , the lower 

 part of which bears against a bowl attached to a lever which rests on the builder rail 

 c 8 . As soon as the lever c* is raised sufficiently high to allow the lower end to pass 

 over, instead of bearing against the bowl, it is drawn' forward by a spiral spring, 

 which causes the backing-off cones to be taken out of contact, when the backing-off 

 ceases, and the operations of running the carriage in and winding the yarn on to the 

 spindles must take place. When the cones are taken out of contact the lower end of 

 the lever N is withdrawn from being over the top of the lever K 1 , leaving that lever 

 at liberty to turn, and the catch-box H 6 thereupon drops into gear, and motion is com- 

 municated to the scrolls H ! and H 2 , and to the cords H S and H 7 . The cord H 5 is at one 

 end attached to the scroll H 1 , and passes thence, round the pulley H 8 , to the ratchet 

 pulley H 9 fixed to the back of the carriage square. The cord H 7 is at one end attached 

 to the scroll H', and passes thence round the pulley H 10 to the ratchet pulley H 1 ' fixed 

 to the front of the carriage square. It will thus be seen that the carriage is held in 

 one direction by one band, and in another by the other band, and that it can only bo 

 moved in either direction by the one scroll giving off as much cord as the other winds 

 on. When the catch-box H 8 drops in gear, the scroll H 1 winds the cord H 5 on and 

 draws the carriage in. It will thus be seen that the carriage is drawn out by means 

 of the back or drawing-out shaft G, and is drawn in by the scroll H 1 . The winding- 

 on of the thread in the form of a cop is effected by means of Mr. Eoberts's ingenious 

 application of the quadrant or radial arm a 7 , screw i and winding-on chain i 4 and i 3 . 

 The chain i 2 is at one end attached to the nut i 1 and at the other to the band i 3 . 

 During the coming out of the carriage the drawing-out shaft through the means of the 

 wheels G 1 , G*, G 4 , and G s , shafts G 8 and G 8 , and pinion G 8 , moves the quadrant which, 

 by the time the carriage is quite out, will have been moved outwards a little past the 

 perpendicular. The chain is moved on to the barrel by means of the cord o, which 

 being fixed and lapped round the barrel as the carriage moves outward causes it to 

 turn. On the barrel is a spur wheel which gears into a spur pinion on the tin roller 

 shaft (these wheels being under the frame side aro not seen in the drawing). The 

 spur pinion is loose on the tin roller shaft, and as the carriage comes out it turns 

 loosely thereon, but as tho carriage goes in the chain i 2 turns the barrel round, and
