Abstract

An impact nailing arrangement having a nail with integral pointed target-penetration and securing forward section, rear hammer section, and medial compression shear section, the forward section having a threaded object-securing surface rearwardly of its pointed forward target-securing end. The nail is propelled into a target in the preferred embodiment by any one of several illustrated latent energy means, and the forward section is secured by initial point penetration and subsequent compression shear of the medial shear section to enable the hammer section to impart a secondary securing impact to the forward section. Various alternative propulsion arrangements including electrical actuation of a powder charge, spring actuation, and valved pressurized gas, are disclosed.

  1. 1. An arrangement for enabling impact nailing, comprisingguide means,a nail unit adapted to be directionally oriented by said guide means,and latent energy means disposable in energy-transmitting relation to said nail unit when said nail unit is disposed in said guide means for imparting linear motion to said nail unit,said nail unit having a forward penetrator section, a hammer section and a medial impact-compression shear section between said penetrator section and said hammer section, and which impact-compression shear section is impact-shearable as a function of energizing said latent energy means and resultant linear motion impacting of said penetrator section with a target object to which it is desired to be attached,said latent energy means comprising propellant gas means,said propellant gas means comprising a supply of propellant gas under static pressure, and selective control means for releasing such gas for forward propelling action on said nail unit.
  2. 2. An arrangement for enabling impact nailing, comprisingguide means,a nail unit adapted to be directionally oriented by said guide means,and latent energy means disposable in energy-transmitting relation to said nail unit when said nail unit is disposed in said guide opening for imparting linear motion to said nail unit,said nail unit having a forward penetrator section, a hammer section and a medial impact-compression shear section between said penetrator section and said hammer section, and which impact-compression shear section is impact-shearable as a function of energizing said latent energy means and resultant linear motion impacting of said penetrator section with a target object to which it is desired to be attached,said latent energy means comprising a spring.
