摘要:
An improved process for securing the metal tines of leaf rakes in which the tines embody a row of notches in the ends thereof which are inserted in a holder. The holder is provided with relief cutouts in areas thereof at the ends of the row of notches. With the parts assembled a suitable tool is brought to bear on the outside surface of the holder, directly over the notches, in-forming an indentation which fits into the notches, thus to lock the tines in the holder. The openings in the holder provide relief for such indentation assuring that it extends completely across the holder and enters all the notches of the complete row of the same.
