Automatic gear.-In a colliery winding - engine, to prevent operation in the wrong direction and premature starting, the engine has reversing-gear which is automatically set and locked by the engine, and is released by the engine man when the banksman and onsetter have conjointly released a control member. The shaft 1 is driven by toothed gearing from the winging - engine and has a sprocket wheel 2 which drives a wheel 3 on a rocking-shaft 4 carrying two guides 5, 6 spaced thereon and carrying chains 7, 8 which pass over rollers 11 on an auxiliary shaft 9, Fig. 3, and support reversing-slides 12, 13, Fig. 1, which have a pin- and-slot connection with levers 14, 15 mounted to slide on actuating-rods 16, 17 connected to the reversing-shaft 19. The arms 14, 15 are loaded by adjustable weights 80 and are connected by cables 21 passing over pulleys 22 to adjustable, spring-mounted cross-pieces 23. A rod 41 from an indicator such as is described in Specification 259,711, [Class 118 (ii), Signals], is connected to a slide 42, and a rod 44 connected to an adjacent indicator is connected to a slide 43 carrying a weight 45. Slides 42, 43 are connected through lost motion and a pivoted lever 47 to a control slide 46 which is not operated until both slides have been operated. Slide 46 rocks a control shaft 53 upon which is mounted a longitudinally-movable tripping member 58 which engages catches 54, 55 holding the slides 12, 13 in their raised positions. The member 58 is brought beneath one or the other catch according to the necessary direction of reversal by mechanism operated by a cam 65 on the shaft 4 thereby ensuring the release of the proper slide 12 or 13. Locks' 67, 67<a> for the starting-handle are provided as described in the above Specification. The starting-lever is locked in its off position until the slide 68 operates to move the lock 67<a>, which takes place immediately after the engine is actually reversed. Slide 68 is actuated by an arm 69 on a crank 70 which is operated by a spring mounted on a rod 72 connected to a shaft 75 carrying arms 74 which are engaged by levers 14, 15. A connection is provided through a chain to a reverse indicator. The slide 68 may be operated by a foot stamp 96. The rod 44 is connected through an indicator with a transparent front and a bell 94.
