The Head Cutter. 

 A is the wood previously planed down to the required thick- 

 ness, and held in its position by the plate B, in connection with a 

 lever, C, operated by the foot at D. The wood A, out of which 

 the head has to be formed, and the plate B, are made to revolve 

 by the belt E. The head is then cut and chamfered on both 

 sides at the same time, by the knives F and G, operated by a 

 lever. 



About one-half of one-horse power is required to operate the 

 Head-Cutter. 



The Heads fit firmly with mathematical exactness, and are 

 formed so much alike, and equal, that it is impossible to mis- 

 place them. 



Staves for shooks, manufactured by this machinery, require no 

 marking, but a given number of staves necessary for a cask may 

 beset up promiscuously, and they form a perfectly tight joint j 

 while, by any other process truss hoops must be employed, and 

 each stave marked, so that when set up for use, they must occupy 

 the relative position given to it by the manufacturer. The expe- 

 rience of commerce demands for general packing purposes pre- 

 cisely the qualities which the cooper attempts to give a barrel or 

 cask, namely, convenient size for handling, roundness for rolling, 

 projecting chimes to be seized in hoisting, and swelled bulge to 

 allow of tightening by driving the hoops. Economy demands 

 that the whole should be wood in separate pieces; but a due 

 regard to elficiency and tightness requires a high degree of per- 

 fection in the workmanship. \A silver medal awarded.
