Abstract
In a Blade Sharpener having a vise to hold a blade, an elongated sharpener reciprocally movable across the edge of the blade, and a guide on the vise to guide the sharpener, the provision of a clamp and bracket to removably support the vise on a stationary support in a preselected position in preselected attitude relative to the balde and sharpener.
Claims8
In the combination of a support clamp, a vise adapted to pinch a blade having a cutting edge to be sharpened, an elongated sharpener engageable with said cutting edge for longitudinal reciprocal movement thereacross, and a guide pivoted on the vise on a guide axis and holding the sharpener in its path of reciprocal movement, the provision of, a post extending outwardly from said clamp in a direction parallel to a guide plane containing the guide axis, bracket means pivotally supporting said vise on said post on a support pivot axis generally transverse to the direction of the post, and positioning said vise and said guide and said sharpener with the sharpener extending generally across the post and next adjacent to and spaced from said post.
In the combination of a clamp and a vise adapted to pinch a blade having a cutting edge to be sharpened and an elongated sharpener engageable with said cutting edge, the provision of guide means extending outwardly from opposite sides of said vise and guiding said sharpener in longitudinal reciprocal movement transverse to and on the preselected of either side of the cutting edge, a post extending outwardly from said clamp in a direction generally parallel to and spaced from said guide means, a bracket pivotally mounted on said post and pivotally supporting said vise in such manner that said sharpener may be positioned for reciprocal movement on the preselected side of said post.
The structure of claim 15, wherein said guide means is mounted for rotation about a guide axis disposed parallel to the axis of mounting of the vise on the bracket, said guide means permitting movement of said sharpener along a longitudinal reciprocal line of movement through said guide axis and in a plane including said cutting edge, said plane intersecting said axis of mounting said bracket on said post and said axis of mounting said vise on said bracket.
