AMERICAN INSTITUTE. 75 



Machine for Preparing Planing, Tonguiyig and Grooving at one 



Operation. 

 C. B. Morse, Rhinebeck, N. Y. This machine always removes the 

 same quantity of wood in forming the tongue and cutting ofl' the 

 waste, and preserving the waste whole if the board should chance 

 to be wider at one end than the other. In other machines, the 

 cutters that remove the waste by having a greater quantity of wood 

 at one point than another, draw the board away from the line edge 

 which is entirely overcome by this improvement. Improvement 

 in preparing and tonguing at one operation, while the planing and 

 grooving is done at the same time. The peculiarity in this machine 

 is in the cutters that form the tongue working from opposite sides, 

 having projecting bills that cut through the plank and take off 

 the excess of width in form of a strip. [Ji gold medal aivarded.
