摘要

Improvements in the hammers for the mechanical detachment of coal or other minerals, mainly in flat strata, characterized in that it has at least one body of a hammer provided with teeth, which is dragged along the coal exploitation pit with so much , velocity, while at the same time being in a direction transverse to that of the traction under a force of recoil so strong, that in a continuous alternative, due to the protrusions of the coal pit with which they meet their teeth, it bounces off the coal pit and by the force of recoil it is thrown back against it, the teeth detaching the minerals at the impact site, the body of the ram being mounted transversely to that of the traction in a movable manner on a chassis moved by means of traction that holds the means back.
