ClipArt ETC

The Pulleys ClipArt gallery offers 87 illustrations. Pulleys use ropes, cables, or belts along with grooved wheels to change the direction of an applied force or to increase mechanical force in a linear or rotational system.

"Many wheels may be combined together, and in many ways, to form compound pulleys. Whenever there is but one rope running through the whole, as shown here, the relation of power and resistance is known by the number of folds, or turns, of the rope which supports the weight." — Goodrich, 1844

An illustration of an inclined plane pulley. "Let the weight w be started to move p the plane, and let P be the pull in the cord which just keeps up steadily the motion imparted to w. Then id l is the length of the plane and h its vertical height, it is evident that when w rolls the whole distance l, P falls through the same distance since the length of l of cord passes over the pulley." -Britannica, 1891

"In the single moveable pulley, the same rope passes from the fixed point, A, to the power, P. It is evident here, that the weight, W, ten pounds, five pounds will be supported by one string, and five by the other. The power will then support twice its own weight." -Comstock 1850

This is used on the upper end of two extension ladders in place of cornice hooks, where the building is not too high. The upper blocks are hooked on as shown in the picture and the stage platform swings between the ladders and the wall.

This shows the old fashioned rope stirrup rigging. The scaffold as a whole consists of a platform twenty inches wide and from ten to twenty feet long. (This platform is an especially strong ladder with planks secured to the rungs.) Cross bars, the timbers under the platform constitute the lower part of the stirrups. They have roller wheels in the ends which are in contact with the building. Then there are the rope stirrups which fasten the cross bars to the lower block as shown in the picture. The falls (pulley blocks and ropes) and the cornice hooks complete the scaffold.

"In order that the successive wheels should revolve in the same time, and their circumfrences should be just equal to the length of rope passing between them...By this construction, although the length of rope passing over each was different, yet their revolutions are equal, both with respect to time and number." -Comstock 1850

A windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end.
