ABSTRACT:
The cost effective hand held tool of this invention has a one-piece housing and a elongated driving piston that can assist the user in driving nails. The piston is made of a metallic material having been magnetized to hold the nail at one end. A striker plate is provided at the first end of the piston for ease of striking by a hammer. The housing is made of an impact resistant nylon that can absorb blows from a hammer without braking. A large hand protecting collar is provided to protect a hand of the user. The tool is indexed to be able to properly position nails of different size within the housing prior to being driven. A two part indexing mechanism is provided by having a plurality of index elements being formed from the housing that engage one of a plurality of index grooves on a length of the elongated piston. Each index groove has an index position to correspond to the standard length of a nail. Index positions are identified by a number to agree with the standard nail designations 6d, 8d, 10d and the like. Metric or other designations can also be used. By setting the piston at an index position, a nail having the size designation is placed in the bore of the housing to contact a second end of the piston. In this position, the nail is guided and will be held approximately flush with the lower end of the housing ready to be driven.
