The two _Side-Rails_ on either side the _Press_ are _Tennanted_ at each end, and let into Mortesses made in the _Cheeks_ and _Hind-Posts_, so as they may stand Range with the outer-sides of the _Cheeks_ and _Hind-Posts_; But the _Tennants_ that enter the Mortesses in the _Cheeks_ are not pin’d in with Wooden Pins, and Glewed, because they may be taken assunder if need be; But are Pin’d in with Iron Pins, made a little tapering towards the entring end, so as they may be driven back when occasion serves to alter the _Press_: And the _Tennants_ that enter the Mortesses in the _Hind-Posts_ are fastned in by a Female-screw, let in near the end of the _Rail_, which receives a Male-screw thrust through the _Hind-Posts_, even as I shew’d in §. 4. the _Fore_ and _Back-Rails_ of the _Case-Frames_ was. ¶. 8. _Of the_ Ribs _marked_ b _in_ Plate 6. The _Ribs_ lye within a Frame of four Foot five Inches long, one Foot eleven Inches broad; its two _End-Rails_ one Inch and an half thick, its _Side-Rails_ two Inches and an half thick; and the breadth of the _Side_ and _End-Rails_ two Inches and an half. But the _Side-Rails_ are cut away in the inside an Inch and an half towards the outer-sides of the _Rails_, and an Inch deep towards the Bottom sides of the _Rails_, so that a square _Cheek_ on either _Side-Rail_ remains. This cutting down of the _Outer-Rails_ of the _Frame_ is made, because the Planck of the _Carriage_ being but one Foot eight Inches and an half broad, may easily slide, and yet be gaged between these _Cheeks_ of the _Rail_, that the _Cramp-Irons_ Nailed under the _Carriage Planck_ joggle not on either side off the _Ribs_, as shall more fully be shewn in the next §. Between the two _Side-Rails_ are framed into the two _End-Rails_ the two _Wooden-Ribs_ two Inches and an half broad, and an Inch and an half thick; they are placed each at an equal distance from each _Side-Rail_, and also at the same distance between themselves. Upon these two _Ribs_ are fast Nailed down the _Iron-Ribs_, of which more shall be said when I come to speak of the Iron-work. ¶. 9. _Of the_ Carriage, Coffin _and its_ Planck, _marked_ a _in_ Plate 7. The _Planck_ of the _Carriage_ is an Elm-Planck an Inch and an half thick, four Foot long, and one Foot eight Inches and three quarters broad; upon this _Planck_ at its fore-end is firmly Nailed down a square Frame two Foot four Inches long, one Foot ten Inches broad, and the thickness of its Sides two Inches and an half square; This Frame is called the _Coffin_, and in it the _Stone_ is _Bedded_.
