Iliyw long should the reverse-lever be? Answer. The lever should be suthciently long, so that inthrowing the link from full gear forward to full gear backwardthe handle // will move not less than four limes the distancethat the link is moved. It is much better to give the end of thehandle five or even si.x times the motion of the link, as therewill then be a much easier action in reversing the engine. Thiswill also make it possible to use longer sectors and give roomfor more notches. QtESTlON 39S. What provision is made in the reversing gearfor overcoming or neutralizing the weight of the link and otherparts of the valve-gear? Answer. Their weight is counterbalanced by the pressure ofa spring of some kind. In fig. igS the case // contains a. Fig. 251. country are usually called quadrants, but in England are called(and more properly) sectors. These are placed on each side ofthe reverse-lever and are fastened to some portion of the engine.They have notches, n n n, cut in them to receive the latch I, which slides in a clamp, c, and holds the leverse-lever in thenotches in which it is placed. This latch is operated by a trig-ger, t, which is grasped by the locomotive runner when he takeshold of the handle H of the reverse-lever. The trigger workson a pin. e, as a fulcrum, and is attached to the latch by a rod, r r. When the trigger is pressed up against the handle, thelatch is raised out of the notches by the rod r r, and is pressedinto them again by the spring s when the trigger is released. * TyiK/oot-doard 93, plates III and IV (see Journal for May), is a platformfor the locomotive ninner and fireman to stand on, and is located at the backend of the engine. spiral spring (of the form
