But, as the nails are longer, it would end of a slip of iron, which is introduced be- be too laborious to cut them by the same motween the cutters.

It is during the ascent of the convenience of the workman, and to enable him piercer that another nail is dropped down from to work at the different sides, he remains seated the wheel through the tube, and received into before the table.

This frame is intended to hold fast the nail lies ciose by the side of the piercer. But, leather which is placed beneath the frame; the when the piercer has risen up completely out of interior opening of the iron frame is nearly of the cell, its two halves spring together, and the the same size and shape as the sole of the shoe. joint in which the nail is placed being formed with The sole is placed flat upon the table, in the faces inclining inwards, they throw the nail into proper position, which is determined by two the cell itself, in which it drops down till it sticks gauge pins fixed into the table, and entering the fast; because, as before stated, the cell is smaller holes made in the sole; then the iron frame, at the bottom; and in this situation the nail is being turned down upon the leather, will enclose certain to be held perpendicular, with its head the sole as it were with an iron hoop, or raised under the point of the piercer.

When he has with this tooi !ying in the bottom of a cell of iron, of the same pared down that part of the edge which is figure as itself, and with the nail points pro- uppermost, he releases the screw of the press, jecting upwards from the sole.

This leaves the spindle at the curves of the outline of the sole. As fast as liberty to be turned round, and the sole turns any part of the length of the strip is settled to with it, so as to bring up a new part of the edge its position, it is attached to the sole by striking of the leather to a convenient situation to be it down with a mallet upon the points of the pared or cut; and the screw is then turned to nails.
