Abstract: A harness bracket 10 comprises a first securement member 12 and a second securement member 14. The harness bracket 10 is arranged, in use, to be mounted to a carriage used in harness racing or trotting where the carriage is pulled along by a horse. A harness bracket 10 is mounted on to two shafts extending from the carriage 11 in order to secure a harness therebetween. The second securement member 14 is movable relative to the first securement member 12 in order for the securement means (i.e. a securement plane or the plane of the harness) to move towards an optimal plane for transferring the forces from the horse to the carriage 11 through the shafts 15. Accordingly, as the horse turns out of the line of the wheels 60 of the carriage, the second part 14 of the harness bracket 10 move and pivot to provide a securement plane at an angle to the plane of the wheels.

Abstract: A brake accelerator is operable sequentially upon each successive braking stage over the service application range of brake line pressure reductions and is employed with a single release brake control valve of an indirectly acting compressed air brake for railway vehicles. The control valve has a service brake portion and an emergency brake portion provided with a emergency brake piston one side of which is subjected to brake line pressure and the other side is subjected to auxiliary chamber pressure . The accelerator has a main piston which operates an inlet valve to connect the accelerator to the brake line. The main piston which is also subjected on one side to brake line pressure and the other side to auxiliary chamber pressure is moved to a service position upon an application of the brakes to open the inlet valve and connect a control piston with the brake line such that the control piston is subjected on both sides to brake line pressure.
