In the upper half of the Mold, at about a Pica distance from the Throat, is fitted into the under-side of the Body the Nick: It is made of a piece of Wyer filed flat a little more than half away. This Nick is bigger or less, as the Body the Mold is made for is bigger or less; but its length is about two m’s. It is with round Sculptors let exactly into the under-side of the Body.
In the under half of the Mold, is made at the same distance from the Throat, on the upper-side of the Body, a round Groove, just fit to receive the Nick in the upper half.
¶. 9. Of the Bow or Spring.
This is a long piece of hard Iron Wyer, whose Diameter is about a Brevier thick, and hath one end fastned into the Wood of the under half of the Mold, as at h; but it is so fastned, that it may turn about in the Hole of the Wood it is put into: For the end of it being batter’d flat, a small Hole is drilled through it, into which small Hole the end of fine Lute-string Wyer, or somewhat bigger is put, and fastned by twisting about half an Inch of the end of the Lute-string to the rest of the Lute-string: For then a considerable Bundle of that Wyer, of about the Size of a Doublet Button, being wound behind the Hole, about the end of the Spring, will become a Sholder to it, and keep the end of the Spring from slipping through the Hole in the Wood: But this Button or Sholder must also be kept on by thrusting another piece of Wyer stiff into the Hole made on the end of the Spring, and crooking that Wyer into the Form of an S, that it slip not out of the Hole.
The manner how the Spring is bowed, you may see in the Figure: But just without the Wood is twisted upon another Wyer about an English thick five or six turns of the Wyer of the Spring, to make the whole Spring bear the stronger at its point: For the Office of the Spring is with its Point at g, to thrust the Matrice close against the Carriage and Body.
¶. 10. Of the Hooks, or Haggs.
These are Iron Wyers about a Long-Primmer thick: Their Shape you may see in the Figure: They are so fastned into the Wood of the Mold, that they may not hinder the Ladle hitting the Mouth. Their Office is to pick and draw with their Points the Break and Letter out of the Mold when they may chance to stick.
¶. 11. Of the Woods of the Mold.
All the Iron Work aforesaid of the Mold is fitted and fastned on two Woods, viz. each half one, and each Wood about an Inch thick, and of the shape of each respective Bottom-Plate. The Wood hath all its Sides except the hind-side, about a Pica longer than the Bottom-Plate; but the hind-side lies even with the Bottom-Plate. The Bottom-Plate, as afore was said in ¶. 2. of this §. hath an Iron Pin on its under-side, about half an Inch long, with a Male-screw on its end, which Pin being let fit into an Hole in the Wood does by a Nut with a Female-screw in it draw, all the Iron Work close and fast to the Wood.
But because the Wood is an Inch thick, and the Pin in the Bottom-Plate but half an Inch long, therefore the outer or under-side of the Wood (as posited in the Figure) hath a wide round Hole made in it flat at the Bottom, to reach within an English, or a Great Primmer of the upper-side of the Wood. This round Hole is wide enough to receive the Nut with the Female-screw in it; and the Pin being now long enough to receive the Female-screw at the wide Hole, the Female-screw may with round nosed Plyers be turned about the Male-screw on the Pin aforesaid, till it draw all the Iron Work close to the Wood.
