SCISSORS SHARPENER Filed Jan. 8, 1954 J, Scor? ai.; eL-6M Patented June 19, 1934 SCISSORS SHARPENER John Donald Scott, Smiths Falls, Ontario, Canada Application January 8, 1934, Serial No. 705,743 In Canada March 31, 1933 1 Claim.

My invention relates to a device for sharpening scissors and the like.

An object of the invention is to provide a device by which scissors and the like may be sharpened easily, expeditiously and accurately, the cutting edges being given a uniform bevel throughout.

Another object of the invention is to design such a device to a very simple and durable construction, with the component parts readily accessible for inspection or repair.

Another object of the invention is to so design the device that scissors may be accurately sharpened without requiring any particular care or skill on the part of the person so using the device, the scissors automatically assuming the same and correct sharpening position when in process of being sharpened.

And generally, the objects of the invention are to manufacture an inexpensive and improved such device.

In the drawing, wherein like numerals of reference indicate corresponding parts in the Various figures,

Figure 1 is a view of the device complete.

Figure 2 is a side view of Figure 1.

Figure 3 is a section on line 3--3 in Figure 1.

Figure 4 is a fragmentary, enlarged View of Figure 1, one sharpening roller` only being shown.

Figure 5 is a fragmentary enlarged view of Figure 1.

Figure 6 is a perspective view of the device showing scissors in process of being sharpened.

The device preferably takes the form shown in the drawing, having a bracket adapted to be secured to a table for instance, and two sharpening elements or rollers disposed, respectively, adjacent the ends of blade receiving recesses made in the bracket; the rollers are also so disposed with respect to the recesses that by working or sliding both blades of the scissors in the recesses, the blades automatically assume the same and correct sharpening position.

Referring now by numerals to the drawing, C is the device complete. The bracket has a member 1 on which are mounted the sharpening elements or rollers 2. One end of the bracket may be formed with an angularly disposed leg 8 having screw holes 4 whereby the bracket may be mounted on a table for instance.

In the opposite parallel edges of the portion 1 of the bracket are two recesses 10, preferably Wedge-shaped as shown, the recesses being dened by straight edges 3 and 3A. The edges 3 are in alignment and are preferably at right an- (Cl. 'Y6-82.2)

gles to the longitudinal axis of the portion 1 of the bracket.

Positioned adjacent the ends of the recesses are the sharpening elements, these taking the form of hardened steel rollers 2. The rollers are secured in position as with rivets or pins 5, and should preferably be so mounted as to be loose or rotatable.

The axes of the rivets are mounted at right angles to the plane of the portion 1 and disposed 65 outwardly or offset from the edges 3, as best shown in Figure 5. With the rollers so disposed with respect to the recesses and more particularly with respect to the straight edges 3, the scissor blades A Will be forced in opposite directions against the edges 3 (or in the direction of the arrows) when the scissors are in process of being sharpened, so that the scissors will always assume the same and correct position. The cutting edges will thus be sharpened uniformly and correctly, being given a uniform bevel throughout.

As willr be readily understood by reference to Figure 6 particularly, the blades of the scissors are inserted into the recesses and moved one towards the other by pressure on the handle loops, while the scissors are slidden to and fro.

What I claim isz- A sharpening device for, scissors and the like having a, member formed with two spaced, substantially wedge-shaped recesses adapted to receive the blades of the scissors, said recesses having two aligned straight edges, circular sharpening elements mounted on said member with their centres outwardly of the aligned edges whereby the blades may be forced sideways in opposite directions into engagement with the aligned edges, respectively, when the blades are moved toward one another.
