1 Claim.

This invention appertains to new and useful improvements in the general art of abrading, and more particularly to a novel scissors sharpener.

The principal object is to provide a scissors of the present invention sharpener wherein means is provided for guiding the sharpening element at the proper angle During the course tion, other important objects and the invention will become apparent In the drawings:-

with respect to the work. of the following specificaadvantages of to the reader.

Figure 1 represents an end elevational view of the device.

Figure 2 represents a side elevational view of the device.

Figure 3 represents a perspective view of the scissors support and guide means,

in separated relation.

Figure 4 represents a stantially on line 4-4 with the parts sectional view taken subof Figure 2.

Figure 5 represents a perspective View of one of the clamp elements of the sharpening device.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figures 1 and 3 that numeral 5 generally refers to an elongated plate having openings 6 therein through which suit able securing elements '7 can be disposed for securing the plate to a work bench 8 or some other suitable supporting structure. Numeral 9 repres ents an upstanding flange at one end of the plate 5 to which a plate 10 is secured. This plate is provided with an inclined upper edge against tion of a scissors blade which the back porcan rest so that the cutthe Winged screw 12 into the aforementioned plate 10, as in the manner substantially shown in Figure 1.

At the end of the plate 5, opposite from the end having the flange 9, is located a threaded opening 13 for receiving the threaded lower portion of the upright 14.

On this upright 14 is slidable the collar 15 which has a set screw 16 whereby this collar can be retained at any adjusted position on the upright 14. Extending laterally from the colla an upturned free end p r 15 is the arm 1'? having ortion 18.

Numeral 19 generally refers to the sharpening device. This sharpening device consists of an abrading represents an elongate stone 20 and a file 21.

Numeral 22 d handle in the form of a U-clamp, the inner sides of the free ends of this handle clamp being provided with bosses 23 which are engageable into recesses 24 in the corresponding ends of the stone 20 and file 21. A screw 25 connects the free end portions of the clamp handle to clamp these boss carrying ends of the clamp against the

elements

20 and 21.

Numeral 26 represents the clamp of like construction, but shorter, the same being provided with bosses 27-27 to engage into corresponding recesses 2828 in the stone 20 and file 21. A screw 29 connects the side portions of this clamp 26 so as to bind the free ends of the clamp 26 against the stone 20 and file 21. An elongated guide rod 30 extends from the bight portion of the clamp 26, as clearly shown in Figure 1. Obviously, by engaging one or the other of the elements 20-21 against the cutting edge of the scissors blade 31 retained between the flange 9 and clamp plate 11, and reciprocating the sharpening device with the guide rod 30 resting on the arm 1"], the proper angle can always be maintained while the abrading tool is in operation.

For different pitch cutting edges, the collar 15 can be adjusted on the upright 14.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:--

In a blade sharpener of the character described comprising a base plate having a blade clamp at one end thereof, an upright at the opposite end of the plate, an arm provided with a collar at one end slidable on the upright, a securing element on the collar for engaging the upright and retaining the collar in adjusted position thereon, a sharpening tool, said sharpening tool being provided with an extension adapted to be guided along the said arm as the tool is moved along the blade being sharpened.
