 EMI1.1 
 
Bei den Kolben von Verbrennungskraftmaschinen wurden bisher zum Abheben in den Kolbenböden gewöhnlich zwei   Gewindelöcher   in entsprechender Entfernung   vorgesehen,   in welche Haken zum Einhängen der Ketten und Seile für den Kran eingeschraubt ! werden. 



     Diese Schraubenlöcher   haben jedoch den Nachteil, dass sich in den   Kolbenböden beim  
Betriebe, wobei die   Kolbenhöden   sehr hohen Temperaturen ausgesetzt sind, Risse bilden, welche stets von diesen   Sehraubenlöchern   ausgehen. Es bilden eben die   Schraubenlöcher :   auch dann eine gefährliche Stelle der Kolbenböden, wenn entsprechende   Verstärkungsaugen   - im Innern der   Kolbenböden vorgesehen   werden. Bei den hohen Temperaturspannungen lassen sich Risse im Boden bei Anwendung der vorerwähnten Schraubenlöcher nur sehr schwer vermeiden. 



   Dieser Übelstand soll   gemäss   der Erfindung dadurch beseitigt werden, dass unter   gänzlichem   Fortlassen der   Schraubenlöcher   an Stelle der bisher gebräuchlichen Schraub- haken hakenförmige Laschen a, Fig. 1, benutzt werden, welche in eine Aussparung, z. B. eine Ringnute b des Kolbens eingreifen. Die beiden Laschen a werden durch ent- sprechende Schrauben c verbunden. In diesen Laschen a können Schraubenlöcher für
Schraubösen d oder dergleichen zum Anlegen der Seile oder Ketten eingebohrt sein. Zum
Einführen der Ilakenlaschen a werden die ohnehin vorhandenen Ventil aussparungen e im
Zylinder benutzt. 



   Die Neuerung kennzeichnet sich also dadurch, dass die ohnehin vorhandenen Ventil- aussparungen e zum Einführen der Hakenlaschen a verwendet werden, wobei die Haken- laschen a in eine Ringnute b im Kolben eingreifen. Die Laschen a können beliebiger
Ausführungsart sein, zweiteilig oder einteilig. Sie können unmittelbar in die Nut b ein- greifen oder auch, wie in Fig. 2 dargestellt, durch Vermittlung eines Einschiebekeiles f wirken.

 EMI1.1
 
In the case of the pistons of internal combustion engines, two threaded holes were usually provided at a corresponding distance for lifting in the piston heads, into which hooks for hanging the chains and ropes for the crane were screwed! will.



     However, these screw holes have the disadvantage that they are in the piston crown when
Businesses where the piston heights are exposed to very high temperatures, cracks form, which always emanate from these void holes. It is precisely the screw holes that form: a dangerous point on the piston crowns even if corresponding reinforcement eyes are provided inside the piston crowns. Given the high temperature stresses, cracks in the floor can only be avoided with great difficulty when using the screw holes mentioned above.



   According to the invention, this inconvenience is to be eliminated in that hook-shaped tabs a, FIG. 1, are used, which are inserted into a recess, for example, in place of the previously used screw hooks, without the screw holes. B. engage an annular groove b of the piston. The two brackets a are connected by suitable screws c. Screw holes for
Screw eyes d or the like can be drilled in to attach the ropes or chains. To the
Introducing the Ilakenlaschen a, the already existing valve recesses e in
Cylinder used.



   The innovation is thus characterized in that the valve recesses e that are already present are used to insert the hook tabs a, the hook tabs a engaging in an annular groove b in the piston. The tabs a can be any
Be design, two-piece or one-piece. They can engage directly in the groove b or, as shown in FIG. 2, act by means of an insertion wedge f.

1. Device for lifting the pistons of internal combustion engines, characterized by a gripping tool (tabs a), the hook of which is inserted into a recess (annular groove b)
