Stave-joint′er.
A machine for truing the edges of staves.
Fig. 5583 is a machine for trimming the edges of staves by a descending cut, the stave lying upon a bed and exposing the part to be cut off over the edge, against which the cutter works shearwise.
The cutter is depressed by a treadle and raised by a spring when the foot is withdrawn.

In
