¶. 3. Of the Carriage.

On the Bottom-Plate is fitted a Carriage, (as a) This Carriage is almost the length of the Bottom-Plate, and about a Double-Pica thick, and its Breadth the length of the Shank of the Letter to be cast.

This Carriage is made of Iron, and hath its upper side, and its two narrow sides filed and rubed upon the using File, exactly straight, square and smooth, and the two opposite narrow sides exactly parallel to each other.

On one end of the Carriage, as at g, is made a long Notch or Slit, which I call the Female-Gage: It is about a Double-Pica wide, and is made for the Male-Gage of the other part of the Mold to fit into, and to slide forwards or backwards as the thickness of the Letter to be cast may require.

¶. 4. Of the Body.

Upon the Carriage is fitted the Body, as at b. This Body is also made of Iron, and is half the length of the Carriage, and the exact breadth of the Carriage; but its thickness is alterable, and particularly made for every intended Body.

About the middle of this Body is made a square Hole, about a Great-Primmer, or Double-Pica square; and directly under it is made through the Carriage such another Hole exactly of the same size.

¶. 5. Of the Male-Gage.

Through these two Holes, viz. That in the Body, and that in the Carriage, is fitted a square Iron Shank with a Male-Screw on one End, and on the other End an Head turning square from the square Shanck to the farther end of the Body, as is described at c; but is more particularly described apart at B in the same Plate, where B may be called the Male-Gage: For I know no distinct Name that Founders have for it, and do therefore coyn this:
