guide pulley

There were other, smaller, guide pulleys used in conjunction with these larger wheels.

As far as can be ascertained this happened near to the position of the guide pulley sited on the lower embankment.

The pulleys are known as the jockey pulley or guide pulley (top) and the tension pulley (bottom).

From the inner ends of these rods chains are led, over guide pulleys, to the ends of a winch, situated as shown in Figs.

Of a certainty, the guide pulley wheel footings are of depth, as witnessed by Mr P. Durran, then the boy of nine years.

The main guide pulleys at the top of the incline, round which the rope passed before reaching the winding drum, were over 10 feet in diameter, had cast iron hubs and rims, and 24 wrought iron spokes.

This arrangement is as follows: From each bearing a chain is led, over a guide pulley situated at the top of the guide belonging to that bearing, to an arm fixed on a rocking-shaft placed close to the floor of the vessel.
