Gwilt translation

2On the back faces of the pieces of timber, where they diverge, are fixed socket-pieces (chelonia), for the gudgeons of the axles to work, so that they may revolve freely. The axles at the ends near the gudgeons, are pierced with two holes, so adjusted as to fit and receive the levers. Iron shears are then made fast to the under part of the lower block, whose teeth are received in holes cut in the piece of stone, for the purpose. The loose end of the rope being now attached to the axle, and that turned round by means of the levers, the rope, in winding round the axle, raises the weight to its height and place in the work.

Morgan translation

2Socket-pieces are nailed to the hinder faces of the squared timbers at the point where they are spread apart, and the ends of the windlass are inserted into them so that the axles may turn freely. Close to each end of the windlass are two holes, so adjusted that handspikes can be fitted into them. To the bottom of the lower block are fastened shears made of iron, whose prongs are brought to bear upon the stones, which have holes bored in them. When one end of the rope is fastened to the windlass, and the latter is turned round by working the handspikes, the rope winds round the windlass, gets taut, and thus it raises the load to the proper height and to its place in the work.
