Parallel to the outer-sides of the hind part of the Planck of the _Carriage_, at three Inches distance from either side, is Nailed down on the upper-side of the Planck two Female-Duftail Grooves, into which is fitted (so as they may slide) two Male-Duftails made on the two Feet of the _Gallows_ (as at _d d_) that the _Tinpan_ rests upon; and by the sliding forward or backward of these Duftail Feet, the heighth of the _Tinpan_ is raised or depressed according to the Reason or Fancy of the _Press-man_. At three Inches from the hinder Rail of the _Coffin_, in the middle, between both sides of the Planck, is cut an Hole four Inches square (as at _e e_) and upon the hither and farther side of this Hole is fastned down on each side a _Stud_ made of Wood (as at _f f_) and in the middle of these two _Studs_ is made a round Hole about half an Inch over, to receive the two round ends of an Iron Pin; which Iron Pin, though its ends be round, is through the middle of the Shank square, and upon that square is fitted a round _Wooden-Rowler_ or _Barrel_, with a Shoulder on either side it, to contain so much of the _Girt_ as shall be rowled upon it; And to one end of the _Rowler_ is fastned an Iron _Circle_ or _Wheel_, having on its edge _Teeth_ cut to stop against a _Clicker_, when the _Rowler_ with an Iron Pin is turned about to strain the _Girt_. ¶. 10. _Of the_ Tympan _and_ Inner-Tympan, _marked_ b _in_ Plate 7. The _Tympan_ is a square Frame, three sides whereof are Wood, and the fourth Iron. Its width is one Foot eight Inches, its length two Foot two Inches; the breadth of the wooden Sides an Inch and an half, and the depth one Inch. On its short Wooden-side, _viz._ its Hind-end, at the two Corners is Rivetted an Iron _Match-Joynt_, to be pinned on to another _Half-joynt_ fastned on the _Hind-Rail_ of the _Coffin_. The other end, _viz._ the Fore-end of the _Tympan_ is made of Iron, with a square _Socket_ at either end for the Wooden ends of the _Tympan_ to fit and fasten into. This Iron is somewhat thinner and narrower than an ordinary Window-Casement. Upon the outer edge of this Iron, about an Inch and an half off the ends of it, is made two Iron _Half-joynts_ to contain a Pin of about a quarter of an Inch over, which Pin entring this _half-joynt_, and a _match Half-joynt_ made upon the _Frisket_, serves for the _Frisket_ to move truly upon. In the middle of each long _Rail_ of the _Tympan_, is made through the top and bottom an Hole half an Inch square, for the square Shanks of the _Point-Screws_ to fit into. The like Holes are also made in the _Tympan_, at one third part of its length from the Fore-end or _Frisket-joynt_, to place the _Point Screws_ in; when a _Twelves_, _Eighteens_, &c. is wrought.
