Abstract

Perfeccionamientos en los mecanismos de acoplamiento para máquinas de coser, particularmente del volante al árbol principal de una máquina de coser, caracterizados porque el mecanismo comprende un disco metálico acoplado rígidamente con el árbol principal, un elemento en U flexible, acoplado por la parte inferior a dicho disco, y una leva elíptica dispuesta en el interior de dicho elemento y capaz de asumir dos posiciones de trabajo, en la primera de las cuales fuerza los brazos del elemento en U contra una superficie cilíndrica de dicho volante montado loco sobre dicho árbol principal, mientras que en la segunda posición permite a los dos brazos del elemento en U separarse de dicha superficie circular del volante, forzados a tomar de nuevo su posición de reposo por efecto de su propia elasticidad y por la acción conjunta de un resorte antagonista
