corves

The corves were placed together in a cage, between which and the pit-ropes there was usually from fifteen to twenty feet of chain.

Now when thou hearst a team of corves coming along, pull yon end and open the door.

Thus the engine may move with great rapidity, while it imparts an equable slow motion to the corves ascending in the shaft.

Betwixt these guides, friction-roller sliders are placed, attached to the gin-ropes, to which sliders the corves are suspended.

The reduced value of the corves is forty-nine livres fifteen sols.
