Abstract: This application provides an enhanced method and equipment for forging bow-shape Conjointed rake with one-piece steel. The methods of the present application include: S1: heating the rectangular blank to target temperature; S2: stamping the rectangular blank to mold rake tooth with rake handle blank reserved at both sides, and conduct cutting at the shoulder; S3: horizontally forging and stamping the rake handle blanks at both sides respectively to columnar; S4: heating the rake handle blank locally, stretching the rake handle blank with roll forging machine to mold rake handle, and bending the rake handle back in reverse to the rake tooth; S5: bending the rake handle stretched out from the sides inward and forge the two ends of the rake handle together to form the main body of the bow-shape rake; S6: placing the main body of the bow-shape rake between the convex stamping equipment to stamp the rake tooth.

Abstract: A closed back shovel is fabricated by placing a frog within a back-side cavity of a standard open back shovel head. The frog is configured to fill the back-side cavity of the shovel blade. A tang element interconnects the frog and a forward end of a tool handle positioned within a tool receiving socket of the blade, within a handle receiving socket, to secure the tool handle to the shovel head. A process for assembling a closed back shovel includes the steps of securing the tang element to the frog, heating the tang element and placing the frog within the back-side cavity of the shovel blade so that the tang element extends into the handle receiving socket, and aligning a tool handle with the tang element by inserting the handle front end into the handle receiving socket. The tool handle includes a thermoplastic section in proximity into the front end thereof, having an elongate tang receiving channel.

Abstract: A process for assembling a hand tool includes the steps of heating an elongated tang element fixed relative to the tool head, aligning a front end of a composite tool handle with a rearwardly extending portion of the tang element, and driving the heated tang element into the tool handle. The tool handle includes a thermoplastic section in proximity to the front end thereof, having an elongate tang receiving channel. The heated tang element is driven into the tang receiving channel such that as the tang element engages the tool handle, the thermoplastic section surrounding the tang receiving channel is softened and flows into intimate contact around the tang element and then hardens as the heat of the tang element is dissipated to hold the tang element in place. In one preferred form, the tang element forms a portion of the tool head which is heated and then positioned in a stationary jig.

Abstract: 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.
