Abstract
A fastening tool having a nail stop which positions a nail for driving and is made at least in part of a contact material which can be investment cast and/or hardened. The contact material can resist wear from the action of driving the nail and the movement of a driver blade. The nail stop can be configured to align nails fed from a magazine and can be offset from the longitudinal centerline of the fastening tool. The nail stop can have a head contact length which is 0.5% to 95% of the length of the nail to be driven. The nail stop is used in methods for positioning a nail for driving.
Claims14
A fastening tool, comprising:
- a fixed nosepiece assembly having a nosepiece length and formed of at least a first material and a recess disposed longitudinally along the nosepiece length;
- a nail channel having an inner diameter;
- a nosepiece insert received into the recess of the fixed nosepiece assembly;
- and
- a nail stop integrally formed on the nosepiece insert, the nail stop having a contact surface defining a nail stop height, the contact surface having a nail stop width and adapted to be contacted by a head of a nail to be driven such that the nail is positioned for driving,
- wherein the nosepiece insert has an interface seat at least in part received into the recess of the fixed nosepiece assembly and having a portion projecting away from the nail channel and configured to mate with a portion of a magazine,
- wherein the depth of the recess is greater than the nail stop height,
- wherein the nail stop width is less than the inner diameter of the nail channel,
- wherein the nail stop is configured to have at least a portion of the contact surface configured in the nail channel to receive contact from the head of the nail to be driven, and
- wherein the nosepiece insert has a second material formed of a greater hardness than the first material and a greater hardness than the nail to be driven.
A method for positioning a nail for driving, comprising the steps of:
- providing a fixed nosepiece assembly having a nosepiece length and formed of at least a first material and a recess disposed longitudinally along the nosepiece length;
- providing a nail channel having an inner diameter;
- providing a nosepiece insert received into the recess of the fixed nosepiece assembly;
- and
- a nail stop integrally formed on the nosepiece insert, the nail stop having a contact surface defining a nail stop height, the contact surface having a nail stop width and adapted to be contacted by a head of a nail to be driven such that the nail is positioned for driving;
- positioning the nail to be driven for driving;
- and
- contacting a nail head of the nail to be driven to the nail stop,
- wherein the depth of the recess is greater than the nail stop height,
- wherein the nail stop width is less than the inner diameter of the nail channel,
- wherein the nail stop is configured to have at least a portion of the contact surface configured in the nail channel to receive contact from the head of the nail to be driven,
- wherein the nosepiece insert has an interface seat at least in part received into the recess of the fixed nosepiece assembly and having a portion projecting away from the nail channel and configured to mate with a portion of a magazine, and
- wherein the nosepiece insert has a second material formed of a greater hardness than the first material and a greater hardness than the nail to be driven.
