Truss miter angle saws

Apparatus for successively cutting truss webs to length and cutting cooperating miter angles on the ends thereof, comprising:

• an upright frame having a top wall, an open front and opposing side walls;
• longitudinal workpiece guide means horizontally supported by said frame adjacent its open front for forming a workpiece path;
• means for limiting movement of a workpiece relative to said guide means;
• a pressure cylinder vertically supported by said top wall and having a depending piston rod;
• a disk horizontally supported by the depending end of said piston rod;
• an index rod vertically connected with said disk in radially spaced relation with respect to said piston rod;
• superposed rotary saw means having the planes of the saws normal to each other and normally supported by said disk above the workpiece path;
• power means operatively connected with said cylinder and said saw means for vertically reciprocating said disk and severing a workpiece to length by cutting two miter cuts on respective predetermined angles and,
• indexing means on said disk including a clamp for preventing angular rotation of the disk about the axis of said piston rod during reciprocation of the disk and saws and permitting manual angular rotation of the disk and saw means as a unit for selectively positioning the saw planes relative to the longitudinal axis of a workpiece when the clamp is released.
