   Austrian PATENT LETTERING? 10642. JOSEFHENNELUNDHERMANNFLACHBARTHINGÖLNICZBANYA (HUNGARY).



   Pick and method of making them.



   The present invention relates to an innovation in picks made in one piece with the ear and the method for producing the same, according to which, in order to reduce the material waste and to achieve strong eyes, the pick blades are punched out one after the other from a sheet metal strip with dovetail-shaped projections at the root of the rib so that each blade tip cut forms the section of the next following continuation.



   The drawing shows in Fig. 7 such a finished pick and in the other figures the individual stages of the manufacturing process of the same. The pick consists of sheet a, punched from sheet metal, which has a swallow-like shape at the root of the rib when punched out.
 EMI1.1
 is greatly reduced, since it is precisely the permanent appendages that were previously part of the waste.

   The extensions b1 are now hammered out (stretched) in the pointed vertex of the cutout.
 EMI1.2
 Extension b1, as can be seen from Fig. 4, bent parallel to one another around a corresponding mandrel (1n and one leg receives a cutout b2 at the top and bottom, whereupon the ends of both legs are around the same mandrel (Fig. 5) closed in such a way to form the finished ear b that it receives a double, flat rear wall formed by the leg ends, the outer part of which differs from that provided with the cutouts b2
 EMI1.3
   An iron or steel band d is then stretched around the sfiten walls of the finished bent eye b, which is still attached to the mandrel, like a collar (Fig.

   6), the ends of which are riveted on top of one another on the blade root by means of rivets c, and around the edges of which the protruding edges e of the eye b (Fig. 7) are crimped so that the finished eye b in the side parts has the cross-section of Fig. 8, the cross section of FIG. 9 is given on the rear wall.

Verfahren zur Herstellung der sub 1 gekennzeichneten Hauen, dadurch gekennzeichnet, dass zunächst aus Blechstreifen f die Hauenblätter a an der Öhrseite mit schwalben- schwanzförmigen Fortsätzen bl versehen, derart nacheinander ausgestanzt werden, dass behufs Materialersparnis jeder Blattspitzenscnitt den Ausschnitt je eines BIattfoitsatzes bl ergibt (Fig. 1), worauf die Fortsätze @@ durch senkrechtes Abbiegen um die Wurzelkante gegen die Blattunterseite (Fig. 3) und Umbiegen um einen entsprechenden Dorn zu den Blech- öhren b (Fig. 5) ausgebildet werden, um welche nun ein Vcrstärkungsstreifen d umgebogen wird, dessen übereinandergelegte Enden an der Blattwurzel festgenietet werden (F. 2. A method for the production of the picks marked sub 1, characterized in that first of sheet metal strips f the blades a are provided on the eye side with dovetail-shaped extensions bl, are punched out one after the other in such a way that each blade tip cuts the cutout of one blade set bl in order to save material (Fig. 1), whereupon the extensions @@ are formed by bending vertically around the root edge against the underside of the leaf (Fig. 3) and bending around a corresponding mandrel to form the sheet metal ears b (Fig. 5), around which a reinforcing strip is now d is bent, the overlapping ends of which are riveted to the leaf root (F. g. 6) und um dessen Ränder schliesslich die überragenden Ränder des Blechöhres umgebörtelt werden (Fig. 7).
