ABSTRACT:
This invention pertains to a hammer with a swinging auxiliary head which is used to impart a second imputus or force to the first and fixed head. This auxiliary head is pivotally mounted in a fixed bracket and is restrained in its movement by a ball detent and/or a U or J-clip which limits the swing or selectively holds the two heads together in a contiguous relationship. A spring actuated lever control device is also shown for compressed spring propulsion of the auxiliary head. Two embodiments are also shown for combining the ball detent, spring actuation and holding the two heads in fixed together arrangement. Each apparatus may be employed with conventional rear portions of hammers such as nail pulling claws and ball peen configurations.
