  Sicherheitsvorrichtung für   Schmiedehämmer.   



   Bisher ist es bei   Schmiedehämmern   allgemein üblich, für den   Hanimerbär   oben offene Führungen anzuwenden. Dadurch kann der Fall eintreten, dass bei Bruch des Bärs dessen Bruchstücke aus der Führung hinausgeschleudert werden und beim Herabfallen die Bedienungsmannschaft verletzen. Diese Gefahr besteht insbesondere bei Federhämmern, da der Bär an der Angriffsstelle des Federwerkes die grösste   Beanspruchung   erfährt und bei Bruch an dieser Stelle das Bruchstück durch   das Federwerk n : : ch   
 EMI1.1 
 angebracht ist. 



   Auf der Zeichnung ist die Erfindung durch ein Ausführungsbeispiel veranschaulicht, u. zw. zeigt 
 EMI1.2 
 abgestützt ist und dadurch als Stossdämpfer wirkt. 



   Bei Beginn der Aufwärtsbewegung des Hammerbärs ist das Federwerk unter dem Einflusse des   Bärgewichtes     abwärtsgebogen. Tritt   in diesem Augenblick ein Bruch des Bärs ein, so wird das Federwerk zum Teil entlastet und hat demnach das Bestreben aufwärts zu schnellen. Es ist   zweckmässig,   die Platte   8   in solcher Höhe anzubringen, dass das   aufwärtsgeschleuderte   Bruchstück des Bärs gegen. die Platte trifft, bevor noch die Entspannung des Federwerkes vollständig eingetreten ist, um zu verhindern, dass dem Bruchstück eine grosse Beschleunigung erteilt wird. 



   PATENT-ANSPRÜCHE :
1. Sicherheitsvorrichtung für Schmiedehämmer, dadurch gekennzeichnet, dass an dem   Hammer-   kopf über der Bärführung eine Fanghaube angebracht ist. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Safety device for forging hammers.



   So far, it has been common practice with forging hammers to use open-top guides for the Hanimerbär. This means that if the bear breaks, its fragments are thrown out of the guide and injure the operating team if they fall. This danger exists in particular with spring hammers, since the bear experiences the greatest stress at the point of application of the spring mechanism and if it breaks at this point, the fragment is caused by the spring mechanism n:: ch
 EMI1.1
 is appropriate.



   In the drawing, the invention is illustrated by an embodiment, u. between shows
 EMI1.2
 is supported and thus acts as a shock absorber.



   At the start of the hammerbear's upward movement, the spring mechanism is bent downwards under the influence of the bear's weight. If the bear breaks at this moment, the spring mechanism is partially relieved and therefore has the tendency to speed upwards. It is advisable to attach the plate 8 at such a height that the upwardly thrown fragment of the bear against. the plate hits before the spring mechanism is completely relaxed in order to prevent the fragment from being given a great acceleration.



   PATENT CLAIMS:
1. Safety device for forging hammers, characterized in that a safety hood is attached to the hammer head over the bear guide.
