  • the shaft 29 rotates it carries the circular plate 25a and with it the wheels 21b and 21c.
  • the wheel 21b being in mesh with the wheel 21a causes the wheel 21a to rotate with the same speed of rotation, thatis to say, with the same speed of rotation as the shaft 26, since wheels 21b and 2111 do not rotate independently on their own axes but rotate with the circular plate 251:.

The wire being slack,no movement has taken place of the lever 43, 44, so that the brake shoe 30 is still acting upon the brake drum 28, and so tending to retard the speed of. rotation of the spindle 24. As soon as the shaft'26 commences to rotate the spindle 24 is held momentarily by the action of the brake shoe 3!
