In thisillustration the radius rod is connectedto the lift shaft arm by means of a linkor hanger. In Fig. 4 the radius rod isdirectly connected to the lift shaft armby means of a slip block, the reverseshaft being made in two pieces. To dis-lonnect the radius rod it is necessary onlytl remove the outer section of the lift-liaft arm and remove the slip block. In the general class of accidents, whereit is necessary to block the valve to coverthe steam ports, these may be divided intotwo classes: first, cases where it is neces-sary to take down the main rod; and sec-ond, those in which the main rod is incondition to run. In the latter cases, thedescription already given is consideredgood practice as to leaving the main rodup or taking it down. Taking up thesetwo kinds of accidents in their order,and assuming that the main rod is brokenor the piston rod bent. In the case ofthe inside admission valves, the locomo-tive mav be disconnected and blocked as. This will prevent compression and alsopermit of lubricating the cylinder. .■\s an illustration, assuming that an ec-centric crank, eccentric rod or the footof the link is broken. Fig. 3 shows howthe valve gear may be disconnected insuch cases. Remove the eccentric rod,disconnect the radius rod from the liftingshaft and secure the link block by piecesof wood fitted into both ends of the linkslot, holding the link block securely in thecenter of the link. The valve on the side shown in Fig. 4. Disconnect the rtdiusrod from the lap and lead lever. Sus-pend it clear of the latter. Secure thevalve to cover the ports. There is usuallya set screw or other device for this pur-pose. Clamp or block the crosshead atthe back end of the guides as shown inthe illustration. With the valve motiondisconnected in this way, the reverselever is free to operate the other side,and the locomotive may be r
