The Description and Use of a Joint-Rule fitted with Lines for the ready finding the Lengths and Angles of Rafters, Hips and Collar-Beams in any Square or Bevelling Roofs at any Pitch.
Use I. To lay down a Line, that shall represent any Number of Feet and Inches given or required.
Use II. To increase or diminish a Line to any Proportion.
Use III. To divide a Line into any Number of parts or models under 30.
Use IV. Any two Lines given, to find their Proportion one to another according to any other Number.
Use V. Two Lines being given, to find a Third in continual Proportion to them.
Use VI. To divide a Line in such sort as another Line is divided.
Use VII. To find a mean Proportional between two Lines or Numbers.
Use VIII. To work the Rule of Three by the Line of Lines to 30 or to 3 Num∣bers given to find a fourth, in Geometrical Proportion Direct.
Use IX. To measure flat Measure by the Scale of 30.
Use X. The breadth of a Board given in Inches, and the length in Feet, to find the Content in Feet and Inches required.
Use XI. To measure Timber by the Line of Lines to 30.
Use XII. The Inches, Square, and Length given in Feet, to find the Content in Feet and Inches.
Use XIII. The Breadth of any Frame being given, to find the Length of the Rafter and Perpendicular by Inspection only.
Use XIV. The Breadth of the House and the Height of the Perpendicular being given to find the Rafters Length, the Hips Length, the Dia∣gonal Line, from Corner to the King-post, and any Angle required, in square Frames. What the Perpendicular Height of the Gable end ought to be at true pitch by the last Rule you may readily see, and the better make estimate of the quantity of alteration. Which being once resolved on, then thus proceed.
The Rule to find the Angles of the Rafters and Hips.
Example, and more briefly in a House 20 Foot broad.
Use XV. To find the Lengths and Angles of the Rafters and Hips, or Sleepers, in Bevelling Frames at any Piton.
4. To find the Diagonal Line.
5. By the Diagonal Line and Perpendicular to find the Hips Length, and the Angles at Head and Foot of the Hip or Sleeper.
To find the nearest Distance from the Corner of the Rombus to the opposite Hip set up in his true place.
To find the Angle on the outside of the Hip.
Use XVI. To find the Rafters, Hips and Angles in Bevel and Taper Frames, being broader at one end than the other. See Fig. III.
Then for the Hips Length and Angles thus,
Example in this Figure for the longest Hip.
Use XVII. To find the Length and Angles of every Principal particular Rafter in Frames broader at one end than the other.
Use XVIII. To find the Length and Angles of Collar-Beams in any Roof.
Use XIX. To find the Lengths and Angles of Rafters, and Purloyns in Bevel Frames.
Use XX. The Vse of the Scales to lay down or measure out on Paper, or Board, the Members and Parts of the fine Columns, and their Or∣naments, with their names and measures, digested into a Table, for the more ease and use of Workmen.
