ABSTRACT:
A saw chain rivet spinner includes a base, a support portion secured to and extending upwardly from the base and a spindle sleeve secured to the support portion and spaced above the base. A rotatable spindle, which has an upper end and a lower end defining a generally vertical axis of rotation for the spindle, is slideably mounted with respect to the spindle sleeve for axial movement relative to the spindle sleeve. A spring mounted between the spindle and the spindle sleeve urges the spindle axially upwardly toward a first raised position. A manually actuated cam mounted with respect to the spindle and spindle sleeve is operable selectively to move the spindle axially downwardly toward a second lowered position wherein the lower end of the spindle is proximate the base. A rivet anvil is mounted on the lower end of the spindle for engaging a saw chain rivet when the spindle is moved downwardly to its second lowered position and a rivet support die is mounted on the base and aligned to support the rivet engaged by the rivet anvil. A motor is operably connected to the spindle to rotate the spindle and rivet anvil mounted thereon, and a switch responsive to the position of the spindle actuates the motor only when the spindle is moved downwardly toward the base.
