Abstract

5607. Thomas, J. March 17. Brakes.-Either-side railway-wagon brakes are applied by a lever g, secured to the rocking shaft d and actuated by levers s<1> at either side and opposite ends, one of which is fitted with a catch to hold the brakes off. The lever g has pivoted to it a pawl l, Figs. 4 and 5, to engage a rack c. which may have stops v, v<1>, secured to the usual bracket a. The pawl has a downward projection m to engage a circular boss n on a stud j, working in a slot k in the lever g and secured to a second lever i, which is pivoted to the arm g at h. A pair of links o, o' working in guides o<2> connect the lever i with the arms on the hand-lever shafts, one of which extends across the carriage. The arrangement is such that, on the hand-lever s<1> being raised to release the brakes, the stud j is pushed along the slot and raises the pawl out of engagement, as shown in Fig. 5, with the rack, indicated' by dotted lines. The brakes are held off by a pawl u, Fig. 1, engaging a notched circular plate t on the shaft q<1>, the pawl having a tail u<1> to limit its movement. To apply the brakes, the handle s' is jerked upwards, so that a projection on the plate disengages the pawl, and the handle is brought sharply down before the pawl falls, thus pulling over the levers i, g, till the brakes are set when they are held by the pawl l engaging the rack c.
