Claims
- 1. An adjustable bow knife, comprising in combination:
- a body having
- an elongate back having forward and rearward end portions
- opposed blade support arms extending spacedly, in parallel orientation from the back at each end portion,
- a blade carried between the opposed blade support arms parallel to an adjacent surface of the back and perpendicular to a plane through the support arms, and
- a handle extending rearwardly from the rearward portion of the back; and adjustment structure having
- an elongate adjustment bar having a linear edge facing the blade and pivotally carried between the back and the blade for parallel motion toward and away from the blade, by spaced support arms pivotally supported by the back to extend therefrom in spaced parallel array,
- an elongate adjustment screw extending through a first chamber defined in the body in forwardly angulating orientation to the adjustment bar and pivotally interconnected to the adjustment bar, and
- an adjustment nut threadedly engaged on the adjustment screw and carried in a second chamber defined in the body to extend from the body to allow access for manipulation to move the adjustment bar toward and away from the blade responsive to rotation of the adjustment nut.
- 2. A bow knife having a knife body with an elongate back, spaced cooperating blade support arms extending from the back and a blade carried between the blade support arms parallel to and spacedly distant from an adjacent surface of the back spacedly adjacent to the blade and extending perpendicularly to a plane through the back and the support arms, and an adjustment structure to allow cutting slices of variable thickness, comprising in combination:
- an elongate adjustment bar, pivotally carried between the back and the blade by two spaced support arms that are pivotally supported in parallel array by the back for motion toward and away from the blade; and
- an adjustment screw carried in a first chamber defined in the body and extending through the body, with
- one end of the adjustment screw pivotally interconnected to the adjustment bar, and
- an adjustment nut threadedly engaged on the adjustment screw and carried in a second chamber defined in the body to extend from the knife body to allow manipulation to move the adjustment bar toward and away from the blade responsive to motion of the adjustment nut.
- 3. In a bow knife having a knife body with an elongate back with spaced cooperating blade supporting arms extending substantially perpendicularly from the end portions thereof to mount an elongate blade parallel to a surface of the back spacedly adjacent to the blade and perpendicular to a plane through the back and blade supporting arms, and a handle to aid manipulation carried by the knife body, an adjustment structure, comprising in combination:
- an elongate adjustment bar carried between the blade and the back by two pivotally joined support arms pivotally supported in parallel array by the back of the knife body, and
- means for adjustably moving the adjustment bar relative to the knife blade in the space between the knife blade and the back to determine the thickness of material cut by the knife between the blade and the adjustment bar.
- 4. The bow knife of claim 3 wherein the means for adjustable moving the adjustment bar comprise
- an elongate adjustment screw carried in a first chamber defined in the knife body to extend in angulated orientation to pivotally interconnect the adjustment bar, and
- an adjustment nut threadedly engaged on the adjustment screw and carried in a second chamber defined in the knife body to project from the knife body to allow manipulation to move the adjustment bar toward and away from the knife blade responsive to rotation.
