Stave-cham′fer-ing ma-chine′.

One for beveling the ends of staves at the chine.

Chamfering and crozing machine.

Fig. 5575 is a machine for chamfering the ends of and crozing barrel-staves at the same time. A stave is inserted in the machine, held by two ribs B at the ends, and clamped between them and a central curved bar K, by means of two vibratable clamps L, operated by segment rack-levers C and pinions at each end of the shaft G. The croze is formed by a toothed cutter a, and the ends are chamfered by upper and lower cutters seen at J. Each stave, as it is inserted, pushes the preceding one forward, they occupying the same relative position as in the completed barrel, uniformity is secured, and splitting off the wood at the edges of the staves is prevented. See also stave-crozing ma-chine.
