rate of speed. The edges of the stave are jointed by cutters on 

 either side of the stave, attached to upright shafts, which stand 

 in a radial line to a centre, whose distance is equal to the radius 

 of the circle of the cask, and which have a sidewise movement, to 

 enable the cutters to be moved from each other as the stave passes 

 between them, as far as the centre of its length, and towards each 

 other, as it passes from the centre to its opposite ends, to give to 

 it the requisite arc to produce the " bulge," when the staves are 

 " set up." The cutters maintain their radial line while jointing, 

 so that the staves are cut to the exact bevel required to make a 

 tight joint when they are made into barrels or casks, and they can 

 be adjusted with great facility to joint staves of all widths, from 

 one and a half to six inches, and of lengths from twenty-four to 

 sixty inches, with perfect exactness. The staves are laid upon 

 the bed of the machine by hand, and are then carried by the feed- 

 ing movement to the jointing cutters, and from thence to the 

 dressing cutters, being guided in their progress in a direct line, to 

 prevent " winding," by a simple arrangement; so that all the 

 hand labor required in the operation of the machine is simply to 

 lay the staves upon the bed. 



It will be noticed, that the staves dressed by this machine are 

 straight upon their face, and require to be bent into shape when 

 they are set up; but it is claimed by the inventor, and the state- 

 ment is substantiated by jDractical men, that the saving in time 

 effected in setting up the steamed and bent staves, does not equal 

 their increased cost, and the straight stave is preferred on that 

 account. 



The operations of champering and crozing the staves are per- 

 formed in another machine, invented by Mr, McNish, into which 

 they are carried as they are finished in and leave this one.

These machines work up all kinds of sound materials, regard-

 worked more like a metal than a fibrous substance. A spurious
