Workers in wood are continually annoyed by the disarrangement and un-reliableness of the common and temporary miter box; the engraving shows one of more durable material than wood, one which cannot warp or wear. 

It is made entirely or iron, yet by a simple arrangement of the parts the saw teeth never come in contact with the metal.

It will saw four, six, and eight square, and at any angle, from 45 to 90, the work always being done with perfect accuracy, requiring no paring of joints with plane or chisel, as is so often the case with that done with the common wooden box.

The saw passes through two upright guides, that at the back capable only of being lifted to accommodate the thickness of the piece to be sawed, and also of turning to guide the saw at any angle, while the front one in addition turns in a sliding clamp which can be secured at any required point by a dowel pin and a thumb screw.

The box is planed, both floor and back, so that it is perfect.  The saw is sustained in the guides by its back so that under all circumstances the teeth are kept clear of iron.

This device will recommend itself to all practical workers in wood as durable and exact.  It was patented Nov. 24, 1864.
