MOTION TRANSMITTER EQUIPPED WITH ONE OR TWO DIVIDABLE PULLEYS

摘要

Novelty: motion transmitter equipped with one or two dividable pulleys. Constitution: one or two pulleys dividable into three at least equal sections 11 which are pierced for being each placed on the steady sections of the pulley 10; said steady sections bear projections 12 whereto the supports 14 are connected via two rollers 16 adapted to two gears 19 which -being pressed towards the centre of the pulley by the two openable jaws 20 fixed at the steady point 21 between the two pulleys- are liable to freely move in order to enable the closing and opening of the pulleys at convenience. The divided sections 11 can be outwardly pressed by the aforementioned jaws 20 what implies the increase of the perimeter of the first pulley and the decrease of the perimeter of the second one so that -when said pulleys are connected via a belt 24- the relations of revs become infinitely increased (fig.4). The construction can be constituted of one stable and one dividable pulley (fig.5).
