The next alteration is in the reversing gear. The aircylinder for lilting the motion into back gear, instead ofhaving a large balance weight as usual, works was necessary, however, to have a circular rack fixedupon the screw, with a detent to retain it in position ; andthere was in addition a pinching screw to nip the nut solidto the guide when the engine was in motion, to preventthe chattering which takes place by the varying angle ofthe expansion link. This acts perfectly if the driver willuse it ; but it very often happens that he allows the engineto run held by the circular rack only ; and this chattersaway the thread of the reversing screw and nut. So decided to put an air-brake to hold this, insteadof the catches or pinching screws ; and he makes a rec-.
