Abstract:
A grapple capable of gripping logs for use in the logging industry, comprising:a pair of opposed tongs which are movable about respective pivotal axes, away from one another or toward one another to overlap at a point on the respective pivotal arcs of the tongs diametrically below their respective pivotal axes, each tong terminating in a pointed primary grapple prong;each tong having a pair of opposite sides which are curved inwardly in the same direction, which tong together with the opposed tong defines a primary convex gripping area for gripping objects therebetween, when the opposed tongs of the grapple are moved toward one another;each tong being provided with a secondary grapple prong fixedly and non-removably attached to the tong for movement in unison therewith;each secondary grapple prong being radially more remote from the pivotal axis than the primary grapple prong and being in a plane which is substantially perpendicular to the pivotal axis;each secondary grapple prong further having a pair of opposite sides which are curved inwardly so that the secondary grapple prongs of the opposed tongs define a secondary convex gripping area of smaller dimension than the said primary convex gripping area for gripping objects there between when the opposed tongs of the grapple are moved together to overlap; andeach secondary grapple prong being shorter than the primary grapple prong.
