A “FOOLPROOF" CONTROL. Gear-changing Mechanism on the Triumph.
For the trials rider and partí- cipant in speed events generally a simple and efficient method of gear. changing is absolutely essential. The loss of a fraction of a second in gear changing may quite easily valuable result in the loss of a award.
Recognising this fact, the Triumph Cycle Co., Ltd., of Coven- try, have arranged the gear change on their T.T. Triumph in such a manner that it is practically impos- sible for the rider to miss second gear. On this particular machine) low gear is engaged by pulling the lever up from neutral, and a change. is made into second gear by push
neutral ing the lever down past until it comes to a definite stop. Directly second gear is engaged and the rider's hand releases the lever, it automatically springs out- wards, and, when desired, top gear can be engaged by merely pushing the lever down as far as it will go Thus when changing from low to second it is impossible to overshoot second gear. position, as the lever cannot pass the correct place until it has made its outward movement. A similar arrangement holds good when changing down, the only dif ference in this case being that the lever must be pressed inwards when ehanging from second to bottom.
A sliding "T" plece in the con- trol axle provides a definite stop for second gear by coming in con- -fact with adjustable set ping in the
gear box control tower, this plece deriving its sliding movement from the spring-loaded gear lever. The actual gears are operated by sliding forks, projections on which engage in slote formed in the con trol cam plate, the latter, of course, being actuated by the gear lever. Definite location after engagement is provided by a spring plunger in the control tower engaging with holes in the cam plate. This new gear is simple, neat and very strong. I la quite sure and pool- tive in action, and marks one more of the many advances in motor cycle design which have emanated from the famous Triumph Corapany of Coventry.
