. Spons' dictionary of engineering, civil, mechanical, military, and naval; with technical terms in French, German, Italian, and Spanish . The segments are described from the centre of the hinge A, and light portion requires to be cut outto permit the passage of the leaf of the hinge A B. Figs. 39G0, 39G1, illustrate an example of acentre-pin hinge, the door opening eitlier way, and folding back against the wall in either E F at right angles to the door, and just clearing the line of the wall, which represents theplane in which the inner face of the door will lie when folded back against the w^all in eitherdirection. Bisect E F in B ; draw A B perpendicular to E F, which make equal to E B or B F,then A is the position of the centre of the hinge. To find the centre of the hinge, Figs. 3962, 3963 ; draw A D, making an angle of 45° with theinner edge of the door, and A B parallel to the jamb, meeting D A in A the centre of the hinge ;the door, in this case, will move through a quadrant D C. 1882 HINGING. Figs. 3966, 3967, are of another variety of centre-pin hinging, opening through a distance o
