About the place where the middle of the _Carriage_ lies, is made a Hole about a _Great-Primmer_ square, into which is rivetted on the upper-side a Pin with a Sholder to it, which reaches about half an Inch through the under-side of the _Bottom-Plate_. This _Pin_ on the under side the _Bottom-Plate_ is round, and hath a _Male-Screw_ on its end. This _Pin_ is let through a Hole made in the Wood of the _Mold_ to fit it; so that when a square _Nut_, with a _Female-Screw_ in it, is turned on the _Male-Screw_, it may draw and fasten the _Half Mold_ firm to the Wood. The Hind side of the _Carriage_ lies on this _Bottom-Plate_, parallel to the Hind side of it, and about a _Two-Lin’d-English_ within the Hind Edge of it; and so much of this _Bottom-Plate_ as is between the _Register_ and the left-hand end of the _Carriage_ (as it is posited in the Figure) is called the _Stool_, as _g g_ in the under-half of the _Mold_, because on it the lower end of the _Matrice_ rests; but on the upper half of the _Mold_ is made a square Notch behind in the _Bottom-Plate_, rather within than without the Edge of the _Carriage_, to reach from the _Register_, and half an Inch towards the left hand (as it is posited in the Figure) that the upper part of the fore-side of the _Matrice_ may stand close to the _Carriage_ and _Body_. ¶. 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.
