Abstract

1528. Bergmann, T. Jan. 19. Belt and rope gearing.-Two sets of stepped pulleys are coupled by a corresponding series of belts n<1>, n<2>, n<3>, any one of which may be put into action by a tension pulley t<1> carried by arms T' on the spindle N<1>. The spindle is connected by a feather and groove to a lever q<3> the head of which is free in the support N<2>; this lever is coupled by a link to a handle P<3>. In order to move the tension pulley opposite the belt it is desired to throw into action, the spindle is also connected to a handlever P as indicated. A modified arrangement for four belts and with two tension pulleys is described. The invention is stated to be applicable for ropes.
