[Illustration: Fig. 258. Devices for Gluing Beveled Edges.]
_No. 58. A ledge and miter or lipped miter joint_, Fig. 268, is made by rabbeting and mitering the boards to be joined so that the outer portion of the two boards meet in a miter. It is strong and good looking and may be glued or nailed. It is used for fine boxes.
_No. 59. A stopped miter_, Fig. 268, is useful for joining pieces of different widths, when both sides can be seen.
_No. 60. A double-tongue miter_, Fig. 268, is made by cutting on the adjoining edges tongues which engage in each other. It is used in high class joinery, on members that join lengthwise of the grain.
_No. 61. A stretcher joint_, Fig. 268, is a slip joint in which one or both sides is mitered. It is used in frames for stretching canvass for paintings by driving wedges from the inside. Two forms are shown in 61a and 61b.
_No. 62. A strut joint_, Fig. 268, is a form of miter joint used in making trusses.
_No. 63 and 64. A thrust joint or tie joint or toe joint_, Fig. 268, is one in which two beams meet at an oblique angle, one receiving the thrust of the other. The toe may be either square as in 63, or oblique as in 64. The pieces are bolted or strapped together with iron. It is used for the batter braces of bridges.
_No. 65. A plain brace joint_, Fig. 269, is one in which the brace is simply mitered and nailed into place. It is used for bracket supports.
No. _66. A housed brace joint_, Fig. 269, is a joint in which the brace is housed into the rectangular members except that the outer end of the mortise is cut at right angles and the inner end diagonally to receive the brace which is cut to correspond. It is much stronger than 65.
_No. 67. An oblique mortise-and-tenon or bevel-shoulder joint_, Fig. 269, is one in which the shoulders of the tenoned beam are cut obliquely and its end is cut off at right angles. The cheeks of the mortise are correspondingly sunk. By these means the tenon prevents lateral motion while the whole width of the beam presses against the abutment. Thus a much larger bearing surface is obtained. The whole is bolted or strapped together. It is used in heavy truss work.
_No. 68. A bridle joint_, Fig. 269, is an oblique joint in which a bridle or "tongue" is left in an oblique notch cut out of one beam. Over this tongue is fitted a grooved socket cut obliquely in the other beam. It is used in truss construction.
