Abstract:
A hammer, intended for manual operation in fastening metal tracks to concrete substrates with a typical track fastener comprised of a radially uniform central steel fastening pin with a fastener point at one end, a fastener head on an opposed end, and a collar enclosing a length of said pin having a maximum diameter of slightly greater dimension than said fastener head, said hammer comprising:a handle possessing a longitudinal axis substantially perpendicular to a striking axis through two opposed striking ends of an integral one piece head fixed to an upper portion of said handle; one said striking end possessing a conventional solid configuration presenting a substantially flat face substantially perpendicular to said striking axis; the other said striking end possessing a cylindrical blind cavity open to an annular face substantially perpendicular to said striking axis and opposed to said substantially flat face presented by said striking end possessing a conventional solid configuration; said other striking end further possessing a substantially cylindrical configuration with a taper inward from a full diameter behind said blind cavity to a reduced diameter possessed by said annular face substantially perpendicular to said striking axis; said cylindrical blind cavity having a substantially flat cavity bottom, a radially uniform cavity wall, and a cavity depth and cavity diameter dimensioned to permit insertion of said typical track fastener; said cavity diameter being approximately equal in dimension to said maximum diameter of said collar and said cavity depth having a dimension lesser than the length of said typical track fastener; whereby insertion of one said typical track fastener into said cylindrical blind cavity disposing said fastener head against said cavity bottom and said collar in slidable contact with said cavity wall and striking the fastener point against a metal track disposed flush to a backing substrate enables starting of said track fastener with penetration of said fastener point through said metal track and into said backing substrate in position for driving home with impacts delivered with said flat face of said conventional solid striking end.
