Fig. 1 is a perspective view, and Fig. 2 a sectional view.
This improvement supplies a want long felt by millers, more especially those who have not the convenience of sending their picks to a good blacksmith who understands tempering steel.
A is a wedge-shaped plate, which is attached to the handle by a screw shank; B is a piece of metal made so as to partly fold about A, as shown, but leaving a space between A and B, in which the steel bit C is held by a lug formed upon it, which fits into a corresponding recess in the plate B, as shown in the section, Fig. 2.
It results from this arrangement that blows upon the bit C, in dressing a stone, more firmly clamp and hold the parts together, while to loosen them, all that is necessary is to tap the plate B on the end opposite the cutting point or edge, which unwedges the two plates and releases the bit.
Two recesses are provided in the plate B, so that when the bit is worn down it can be set further out from between the plates A and B. When one end of the bit becomes so worn as to be no longer available, the bit is reversed, and the other end applied to dressing the stone. Thus the bit may be used until it is almost entirely worn away. It is retained firmly, and yet is instantly detached for sharpening or for adjustment.
The head is made of Malleable Iron, and the blades of the very best quality hammered cast steel, tempered the whole length, and do not require blacksmithing, but only to be ground when dull.
The price places these Picks within the reach of every miller.
Twelve 6 inch double blades sent with each head.
