Page 17 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; and each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds ; and these into thirds, etc.
Page 285 - ... stairs are placed. B shows a portion of a baseboard, the top edge of which has the same finish as the top edge of the string. B and A together show the junction of the string and base. FF show blocks glued in the angles of the steps to make them firm and solid. Fig. 28 shows the manner in which the wall string S is finished at the top of the stairs. It will be noticed that the moulding is worked round the ease-off at A to suit the width of the base at B. The string is cut to fit the floor and...
Page 15 - A convex or concave line is such that it cannot be cut by a straight line in more than two points ; the concavity of the intercepted portion is turned towards the straight line, and the convexity from it.
Page 162 - Code, unless the ashlar be at least eight inches thick and bonded into the backing, and then it may be counted as part of the thickness of the wall. Iron ashlar plates used in imitation of stone ashlar on the face of a wall shall be backed up with the same thickness of brickwork as stone ashlar.
Page 123 - Rule. — Multiply the square of the length in feet by the span in feet, and divide the product by the cube of the thickness in inches; the quotient multiplied by .155 will give the depth.
Page 21 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.

The other end of the riser is in the housing in the wall string. The outer end of the tread is also mitered at the nosing, and a piece of material made or worked like the nosing is mitered against or returned at the end of the tread. The end of this returned piece is again returned on itself back to the string, as shown at N in Fig.
Page 54 - English," which prevailed in this country from about 1189 until 1307. Fig. 58 is the Equilateral arch, the radius with which the arcs are struck being equal to the span of the arch, and the centres being the imposts ; and thus, the crown and the imposts being united, an equilateral triangle is formed. This form was principally used in the " Decorated" period of Gothic architecture from about 1307 until about 1390, at which time the Ogee arch (Fig.

Usually, in stairs of this kind, the ends of the treads are rounded off similarly to the front of the tread, and the ends project over the strings the same distance that the front edge projects over the riser.
