Spons' dictionary of engineering, civil, mechanical, military, and naval; with technical terms in French, German, Italian, and Spanish . into each of the branches, the arrangement of ropes is altered at thisjunction, as the ropes of the way last visited are then on the set. Suppose the set has been last inthe west way, in going inbye again, when it has arrived at this junction, the tail rope at the inbyeend of the set is removed, and replaced by the north-way rope ; the shackle connecting the maintail rope with the west-way branch rope being held by a wooden clamp, fixed at the junction, whilethe end of the north-way rope is being attached to it. This shackle-joint is stopped always at thesame place ; and as the branch-rope end is brought to this point whilst the set is coming inbye,they are connected immediately. As this connection is made by the man attending the junction,while the connection at the end of the set is being made by the nm-rider, the time taken up by thechange is very short, generally not more than two minutes. The annexed sketch, Fig. 3909, shows the position of the ropes just when the tail rope 3909,. has brought the shackle-joint near to theclamp, which is then screwed up. Asbefore described, the west-way rope is thentaken off, and the north-way rope con-nected. When the end of the north-wayrope is not just opposite to this point, it isdrawn up by a winch, fixed here for thepurpose. In coming oMíbye, the set (from eitherway) comes out to the shaft without stop-ping. At the fore end of the set is fixedthe self-acting knock-off link, Fig. the set arrives at the top of the kip,and most of the tubs are over the brow,a piece of iron, fixed to the roof, comesin contact with the arm A of the knock-off apparatus, and releases the main rope,which falls off to one side. The engineis then stopped, and the set is let down bythe tail rope, which is still attached, tillthe first tub (if there are no full tubs stand-ing) reaches the shaft. Whilst g
