Abstract
Abstract Nail clipper of the leaf spring type in which the leaf spring elements of the clipper are superimposed and have facing inturned cutting edges at their proximate ends and are riveted together at their distal ends. A post extending through the leaf spring elements close to the proximate ends thereof forms a reaction member for a lever moving the leaf spring elements together to effect a clipping operation. Extending partially about the post and facing the cutting edges of the leaf spring elements is a nail clipping decelerator and accumulator formed to prevent the flying of nail clippings beyond opposite edges of the clipper and to accumulate the clippings for disposal by opening the clipper and shaking it in a sideways direction. The clippings decelerator and accumulator has arcuate faces extending from opposite sides of the post and cooperating with a recessed arcuate face of the post and also has closed sides extending from the arcuate faces toward the clipping edges of the clipper and has a ledge extending along the tops of the arcuate faces as well as a similar ledge engaging the bottom of the lowermost leaf spring element, to decelerate and accumulate the clippings for the entire width of the lowermost leaf spring element until necessary to dispose of the clippings by opening the clipper blades and shaking the clipper from side to side, with the decelerator and accumulator facing in a downward direction.
