Mechanisms

SIMPLE CHAIN DRIVE
INVERSE CHAIN DRIVE
PULLEY AND ROPE, (uses small pulley to make tension)

                                            ROPE AND PULLEY,(inversing mechanism for loading higher weights)
Adding small movable puuley in mechanism'1', 9when the pulley is pressed the band will transmit the motion, when it is not band becomes slack and will not allow to transmit the motion.)
 (lever IS secured to the semi-circular segment, tHIS imparts a reciprocating rotary motion to the two pulleys below.
(enganging, disenganging of the shafts)
                      Belt & Pulley Mechanism(  used in machine tools for varying speeds, e.g. lathes)
          Cone Pulleys ( e.g. cotton machinaries.)
(just the modification '9', being different shape)

                                                                                        (same as '3' without guide pulley)
                                                                                      (Simply pulley used to weigh the loads.)
( In this the lower pulley is movable. One end of the rope being fixed, the other must move twice as fast as the weight, and a corresponding gain of power is consequently effected.)
(tackle and blocks)

(modification of above, known as white's pulley)

            (spanish bartons,modification in lifting load)
(sopanish barton)
(Two fixed pulleys and one is movable)




( for transmitting rotary motion to a movable pulley. The pulley at the bottom of the figure is the movable one; if this pulley were raised or depressed, the belt would be slackened or tightened accordingly. In order to keep a uniform tension on the belt, a pulley, A, carried in a frame sliding between guides (not shown), hangs from a rope passing over the two guide-pulleys, B, B, and is acted upon by the balance weight, C, in such manner as to produce the desired result.)
