Among the many arrangements for saving labour by the introduction of machinery in the working of wood, nothing has presented so many difficulties as dovetailing. Numbers of machines have been introduced, introduced, but have failed , either from the roughnes of the working, or through the great complexity of the machine employed and the consequent great loss of any work done.
The American Dovetailing Machine here shown was exhibited working at the International Exhibition at Paris and has been acknowledged by all the leading members of the mechanical body as the most perfect machine of its kind ever produced.
The want of such a machine has long been felt, particularly in the box-making, the expense of dovetailing by hand being so costly that nearly all the packing boxes have hitherto been put together with nails. The production of this machine is so great that boxes and case can now be dovetailed together cheaper than nailing.
Each machine is arranged for cutting ordinary dovetails, dovetails on the angle and blind dovetails.
It is quite easy to work. The discs being set to the proper angle, the board is placed on the table, being held fast by a cramp and on motion being given to the machine, it travels along the front of the saw and the dovetail holes are cut clean at the rate of twenty feet of board per minute.
For cutting the pins to fit in the dovetailed holes, it only requires to give half a turn to a handle for partially reversing the disc and the machine is ready for that portion of the work. It is now in use by some of the largest packing case makers, cabinet makers and builder in the country.
They are made of different sizes, as under, to suit various trades, but all do dovetail any thickness from ¼ in. to 1¼ ins. Thick

Size to dovetail any width of board up to 24 ins., including one set of saws; Weight 1½ tons; Power required, ¼ horsepower.
Size to dovetail any width of board up to 36 ins., including one set of saws; Weight 2 tons; Power required, ½ horsepower.
