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: _a_ The _square Shanck_. _b_ The _Male-Screw_. This _square Shanck_ is just so long within half a _Scaboard_ thick as to reach through the _Body_, _Carriage_, and another square Hole made through the _Bottom-Plate_, that so when a _square Nut_ with a _Female-Screw_ in it is turned on that _Pin_, the _Nut_ shall draw and fasten the _Body_ and _Carriage_ down to the _Bottom-Plate_. The Office of the _Male-Gage_ is to fit into, and slide along the _Female-Gage_. ¶. 6. _Of the_ Mouth-Piece. [Illustration: _Plate 19._ _The Upper half of the Mold_] Close to the _Carriage_ and _Body_ is fitted a _Mouth-Piece_ marked _d e_. _Letter-Founders_ call this altogether a _Mouth-Piece_: But that I may be the better understood in this present purpose, I must more nicely distinguish its parts, and take the Freedom to elect Terms for them, as first, _c c e_ The _Mouth_. _d_ The _Palate_. _c c_ e _d_ The _Jaws_. _d d_ The _Throat_. Altogether (as aforesaid) the _Mouth-Piece_. The _Mouth-Piece_ hath its _Side_ returning from the _Throat_ filed and rubb’d on the _Using-File_ exactly straight and square to its _Bottom-side_, because it is to joyn close to the Side of the _Carriage_ and _Body_; but its upper-Side, _viz._ the _Palate_ is not parallel to the _Bottom_, but from the Side _d d_, _viz._ the _Throat_ falls away to the _Mouth_ e, making an _Angle_ greater or smaller, as the _Body_ that the _Mold_ is made for is bigger or less: For small _Bodies_ require but a small _Mouth_, because small _Ladles_ will hold Metal enough for small Letters; and the smaller the _Ladle_, the finer the _Geat_ of the _Ladle_ is; and fine _Geats_ will easier hit the _Mouth_ (in a Train of Work) than the course _Geats_ of Great _Ladles_: Therefore it is that the _Mouth_ must be made to such a convenient Width, that the _Ladle_ to be used and its _Geat_, may readily, and without slabbering, receive the Metal thrown into the _Mold_.
