Description:
Elliott & Hopkins - patent attorneys

My invention relates to that class of nail pullers in which a pair of gripping-jaws are caused to sink into the wood below the head of the nail and to close upon or grip the nail when pressure is applied to the handle of the device like a lever, using a second lever or foot which rests upon the box or board as a fulcrum. The primary object of my invention is to provide a nail-puller in which the jaws will remain normally separated and will firmly hold the fulcrum lever or foot against oscillation, whereby the latter may be employed as a hammer. A further object of my invention is to provide a durable and effective nail-puller consisting of the minimum number of simple members.
