Abstract
Caballete de entibación en el que el talón o contrafuerte de techo está entibado por medios de unos puntales principales que apoyan contra un bastidor de suelo, llevando articulado dicho contrafuerte una placa orientable en inclinación destinada a determinar un plano o guía eficaz para evacuación de carbón, en caso de operar en una explotación en la que se debe extraer el carbón de techo, desembocando dicha placa a un transportador dispuesto en la parte inferior del conjunto y en el lado inmediato a la explotación antigua, caracterizado esencialmente por el hecho de que la placa para evacuación del carbón de techo está entibada a su vez en cada posición adoptable por medio de puntales secundarios que apoyan contra el bastidor de suelo, los cuales van articulados en modo orientable tanto en la placa como en el bastidor de suelo, comportando dicha placa en su seno , al menos una corredera que se puede desplazar en el sentido de su mayor longitud, por medio de la cual se puede modificar la envergadura eficaz de la placa en sus funciones transportadoras del carbón de techo.
