Abstract
Improvements in the manufacture of cutting picks for coal cutting or sawing machines characterized by a cutting pick comprising a shaft and a cutting head forming body with it and in the same plane as the shaft and provided with a cutting face projecting forward in the which an insert or hard piece constitutes the cutting edge and from whose cutting face the head is lowered backwards characterized by the fact that two diametrically opposed non-marginal areas on the lateral faces of the shaft and along the opposite marginal faces of the same shaft over the entire width of said opposing marginal faces they are adapted to limit or limit a tucked and abutted insert surface for the end of a cutting spike fastening screw in a support in which said spike is to be fastened with each indicated stop surface having a spine near the free end of the shaft which is adapted stops so that when the shaft of the cutting tip is held so Slightly engage the retaining screw in the bracket to prevent the cutting spike from accidentally falling completely out of the bracket.
