A and A represent the two handles of my pipe-tongs, pivoted together at d.

The handleA is extended beyond the pivot, substantially in the manner shown in Fig. l, and forms the hook B.

The other handle, A, extends also beyond the pivot, and is bent nearly at right angles, and is provided with an enlargement or head, 0, having shoulder b, which shoulder forms stops for the handles, both in opening and closing.

The bit G is made of angular form in crosssectiou, as shown, and the slot or opening in the head 0 is made of corresponding form, so that the bit can, under no circumstances, be twisted When'grasping a pipe; and when the bit is in position it will readily be seen that it is held firmly, and all movement thereof is prevented, whether lengthwise or in any other direction.
