A further object of the invention is to provide a scissors and shears Sharpener including a flat and horizontally disposed table, means at the rear end of the table for releasably engaging a blade of a pair of scissors or shears and support ing the blade in proper position relative to the `table for bevel sharpening the same, and a ñle with means on the handle thereof for slidably ward îbetweenfthe uppenzm'arglnsmf'‘tlieszmzllatœay Itßis:` to the». notedzthatïthe boltslßìare: spacedì [email protected] ciently below the upper edges of the plates to afford room for the insertion of the blade. Ears II are turned down in laterally spaced relation from the rear end of the table 5 and similar ears I2 are turned inwardly from the lower margin of the inner clamp-plate 8 and adapted to overlle the ears II of the table 5. A pivot bolt I3 is passed through the two sets of overlying ears II and I2, whereby the clamp-plates ‘I and 8 are pivotally supported at the rear end of the table 5 and transversely thereof, and may be tilted more or less angularly to the surface of the table for a supporting the handle in proper spaced relation to the upper face of the table, said spacing corre sponding to the spacing of the upturned edge of purpose to be described. An elongated tab I4 is of Figures 1 and 2„ and as to maintain the ille blade when laid across the struck out and turned down at the rear end of the table 5, inwardly spaced from the rear end there the scissors or shears blade above the table, as of, and another tab I5 is similarly struck out at supported at the rear end of the table, and where the lower margin of the outer clamp-plate 'I and by the file may be -moved and reciprocated is turned inwardly in longitudinal alignment with smoothly and evenly over the cutting edge of the the tab I4. An adjustment link I6 is provided blade for sharpening same. and is pivoted at I'I by its outer end to the tab I5, With the stated objects in view, together with while the inner end of this link is adjustably con such other and additional objects and advantages nected to the tab I4 by means of a bolt I8 passed as may be pointed out in the specification, atten 25 through the tab I4 and through an elongated slot tion is directed to the accompanying drawing, I6a formed in the inner end of the link Iii.
