ABSTRACT:
A device for dislodging an object, for example a cap that is close fit over the top of a pipe, in which a handle and a grip, each formed to be held by the respective hands of a user, are interconnected with a weight member and an impact member, such as a pair of tongs. Slide bars fixed to the weight member are disposed through one end of the grip and connected to the handle. A shank is slidably disposed through the weight, connected to the grip on one side of the weight and to the tongs on the other side of the weight. The tongs include a plurality of pivotally connected links and are formed with elongate arms terminating distally with jaws formed to impact against a horizontally disposed surface of the cap. The tongs tend to close when freely suspended from the shank so as to slip over the cap on a pipe, contacting it from below the cap. Lifting of the handle impacts the weight against the grip to transmit a hammering force to the jaws, dislodging the cap.
