Description.

As seen in the drawings, the holder 12 .for the blade 13 has a flat upper surfaci'r. from which protrudes pins 14 so disposed as to extend through the perforations With which the blades 13 are usually provided. The under or reverse side of the holder 12 is thickened at the center to a height equal to the projection of the pins 14 above the blade 13 when in service. The thickness referred to is herein designated as the ridge 15 and can be best seen in Figures 4, 6 and 7. The ridge 15 provides a rocking surface for the Sharpener when resting on a n strop 16; The samey function is performed by the pins'14-.whendesired, as shown-in Y' Figures 6 and 7 .off draw-ings.`

To 'hold' the: blade 13"'iny service position the spring detent. tung is rigidly secured on the holder'12 by means of the'rifvet-,si As seen in Figuresl and 2, the rivet 19. is

at the narrowed end of the wed-'geq20a with which the holderv is: provided and?V which facilitatesjit beingdriven into the wooden handle 21 with which the sharpener is-.preferably provided..

Beneath the tongue 17, the-holder has of the detent 17 leads.

A t the end of the holder opposite that i having the detent 17 is secured a resilient rlfhe finger' 2 3 extends from a finger" 23. clamp 24` through theielongated-f slot 25 of which extendsastudserew i262' 'The rearfend a .1. recess 22 into which the inclined'undersideA to the blade 13 a nut 27 is furnished, the'v threads of which engage the threads of the screw 26. yWhen the nut 27 is set up on the screw 26, the clamp 24 is forced down on the holder 12 with the result that the finger 23 presses on the Vend of the blade 13 which has been exposed on the holder with the full' strength of the resilient metal of which the said finger is composed. When the nut is retracted as seen in Figure 3 of the drawings, the blade 13 may be readily and quickly lifted from the holder 12 and from engagement with the pins 14.

When^it is desired to clean the holder, the nut 27 is removed and the clamp 24 is lifted from the holder 12 so that the meeting surfaces of the said clamp and the holder may be thoroughly cleaned.

When employing a holder constructed and arranged in accordance with the present inlOO blade 13 is provided, with the pins 14. The blade is then depressed to rest upon the holder l2, the pins 14 protruding through the perforations mentioned. The nut 27 is then set up forcing down the clamp 24 and flexing the finger 23 in the position shown in F ig. 2 of the drawings. VThe finger 23 and the tongue 17 now prevent the blade 13 from being lifted from the holder 12.YV

Usually the blade is sharpened by resting the holder on the strop 16, the ridge 15 being presented to the said strop to form a roclringV surface thereunder. When thus placed on the strop, the holder is carried to the one end of the strop dragging the rear edge of fthe blade Von theV stropping surface. When the blade has been `carried tothe far end of the strop, the holder is rocked on theridge I 16 preparatory to returning the blade to the :initial position and dragging the opposite `trouble of :re-adjusting the blade, he may do v f so using then the pins 14 for rocking the holder and the blade carried thereby.
