Furthermore, the object of the invent-ion is to produce a base for an implement-of the character noted which is in such relation to the implement that the said base may be moved by the foot of the operator in order that it may be properly positioned with relation to the nail or spike to be extracted to attain the best results.

Finally, the object of the invention is to produce adeviceof the character noted which will possess advantagesin points of efficiency,

simplicity, and durability, proving at the same time comparatively inexpensive.

As illustrated, the sides of the claw-head arecut away somewhat to form shoulders I, and the upper. portions of the shoulders are rounded, as at 2, to form bearings for the upper rounded surfaces of the posts. arrangement the supporting-posts may be readily applied and removed and a pivotal pin is dispensed with. Hence an aperture in the claw-head need not be formed.

As shown in Fig. 2, the sides of the claws of the hammer are cut away to form shoulders 3 and a socket or seat 4 for the upper ends of the posts, and the operation and advantages of this construction correspond to the construction and operation described in connection with the disclosure of the invention illustrated in Fig. 1.

The construction, operation, and advantages will, it is thought, he understood from the foregoing description, it being noted that various changes may be resorted to in the proportions and other details of construction for successfully carrying the invention into practicewithout departing from its scope.
