Abstract
A chuck device for driving nails into boards includes a nail-driving mechanism and a staging mechanism for positioning the nails to be driven by the nail-driving mechanism. A driving mechanism drives both the nail-driving mechanism and the staging mechanism for positioning the nails. A countersink control mechanism positioned between the staging mechanism and the driving mechanism provides the capability for selectively changing and fixing a distance between the staging mechanism and the driving mechanisms and a distance between the staging mechanism and the nail-driving mechanism.
Claims9
A chuck device for driving nails into boards wherein the chuck device is mounted to a chuck support frame, the chuck device comprising:
- nail-driving means for driving nails along a path located on a nail driving axis into boards;
- staging means for positioning the nails to be driven by the nail-driving means, the staging means attached to a lower end of the nail-driving means;
- drive means for driving both the staging means and the nail-driving means, the drive means mounted to the chuck support frame;
- countersink control means for selectively adjusting a distance between a surface of the boards and an upper surface of a head of a driven nail, the countersink control means adjustably engaging the nail-driving means and the drive means;
- and
- means for preventing rotational motion of the staging means about the nail driving axis while the distance between a surface of the boards and an upper surface of a head of a driven nail is being adjusted by the countersink control means, the means for preventing rotational motion engaging the staging means and being mounted to the chuck support frame.
