摘要： THERE IS DISCLOSED AN APPARATUS FOR FORMING CLOSING HEADS AT RIVET WITH THE AID OF A RIVET SET OR ANVIL WHICH CARRIES OUT LOOP-LIKE REVOLVING MOVEMENTS. ACCORDING TO THE INVENTION, THE RIVET SET IS SUPPORTED IN A CRANK-LIKE ELEMENT WHICH COOPERATES WITH A DRIVE SHAFT, THE AXIS OF ROTATION OF SAID CRANK-LIKE ELEMENT BEING INCLUDED WITH RESPECT TO THE AXIS OF ROTATION OF THE DRIVE SHAFT. FURTHER, THE CRANK AXIS OF THE CRANK-LIKE ELEMENT IN ONE EXTREME POSITION AS LEAST APPROXIMATELY COINCIDES WITH THE AXIS OF THE DRIVE SHAFT AND IN THE OTHER EXTREME POSITION SUCH CRANK AXIS INTERSECTS THE AXIS OF THE DRIVE SHAFT AT THE REGION OF THE RIVET.

摘要： A novel method is disclosed for fabricating weaving heddles from wire stock by passing the wire through a rolling mill to give the stock a substantially elongated, that is, a comparatively thin and wide cross section. Then a plurality of longitudinal notches are embossed in the stock spaced apart a distance generally equal to the desired length of the heddles, whereupon each notch is spread by means of a wedging tool into an elongated slot to form an eye and there is inserted an eyelet member therein. Thereafter, the individual heddles are cut apart generally midway between consecutive eyes. Each end of the heddle is then formed into a terminal eye by bending between appropriate tool members. The heddles may also be formed from precut sheet stock by bending the ends thereof into terminal eyes by means of tool members generally similar to those used for the wire stock.

摘要： A safety device for machine tools with a tool advancing member in the form of a tool holder performing a tool operating motion during operation and having mechanism for the interruption of the operating motion in the presence of adverse or anomalous operating conditions. According to important aspects of the invention a primary switching or control means is provided for the purpose of interrupting the tool operating motion of the tool holder during a portion of its operating stroke if there is exerted on the tool member a pressure opposing the operating motion. Additionally, secondary switching or control means bridge the primary switching or control means or prevent such from moving into a breaking position as soon as the portion of the operating stroke of the tool has exceeded a predetermined value.
