1 Claim. 1

This invention relates to an improved scissor sharpener, and more particularly to a lightweight, portable scissor sharpener which may be used by persons unskilled in the art of sharpening cutlery to provide a suitable and desirable cutting edge on the scissor blades.

Another object of this invention is to provide a scissor sharpener of the kind to be more particularly described hereinafter, which is so constructed and arranged that it may be manufactured at a low, reasonable cost, to permit a wide distribution. l

A further object of this invention is to provide a scissor-sharpening tool of this kind having spring-pressed, clamping members for securing the blades of the scissors and the sharpening element to the device, the clamping members being so formed that they may be readily opened by finger pressure of the operator.

Yet another object of this invention is to provide a scissor-sharpening tool of this kind having provision for changing the sharpening element. The sharpening element is supported on the tool for movement along the edge of a cutting blade to be sharpened, and so supported on the tool that the cutting element may be adjusted to various, selected, longitudinal and angular positions to accommodate the particular length and the angle of the blade to be sharpened.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a side elevation of a scissor sharpener constructed according to an embodiment of my invention;

Figure 2 is a front elevation thereof;

Figure 3 is a top plan view;

Figure 4-. is a fragmentary detail section, taken on the line 44 of Figure 1.

Referring to the drawings, the numeral designates generally a scissor-sharpening tool constructed to an embodiment of my invention, which is portable in nature, to be moved where desired, or readily carried about by a person desiring to use the tool at any particular position or locality.

The sharpening tool ii) is formed of a flat base member 4 l, which constitutes a supporting plate for the scissors to be sharpened and the sharpening element to be engaged with the blades of the scissors.

A spring-pressed, clamping member [2 is carried by the forward edge to support a blade of the scissors along one edge of the supporting plate or base H. The clamping member l2 consists of a pair of face-abutting jaw members l4 and i5, each having a handle portion, as l6 and. Il, respectively, for engagement through a split ring or sleeve 88. The longitudinal free edges of the split ring it engage the outer faces of the jaw members I4 and 5 for pressing the jaw members together. The handle portions I6 and I! extend through openings, as l9, intermediate the length of the resilient sleeve l8 substantially opposite from the split ends of the tube. The formation of the clamping member I2 is such that the handles [6 and ll are substantially pivoted in the openings IS for pressing the jaw members [4 and i5 divergingly apart upon moving of the handles I6 and I! together.

The forward, marginal edge, as 26, of the base plate II is downturned at right angles to the plane of the plate to provide for the attachment of the clamping member l2. The lower edge of the downturned flange 2% is provided at the corners thereof with a rearwardly-bent ear'portion 2| which is adapted to clampingly engage one of the jaw members, as M, for securing that jaw member to the back side of the flange 26. The jaw I5 is disposed on the opposite side of the flange 20 and the upper edges of the jaw members l4 and it: are disposed slightly below the plane of the upper surface of the base mem ber II. The clamping member I2 is adapted to secure a blade, as B, of a pair of scissors on the forward edge of the base H, in such a manner that the cutting edge of the blade B will be disposed above the plane of the upper surface of the base plate H for engagement with a sharpening element E, to be described hereinafter.

A sharpening element E is adapted to be supported above the upper surface of the base II for engagement with the edge of the blade B of the scissors S to be sharpened. The sharpening element E is adapted to be clamped in a resilient clamping member, as 22, above the base H. An arm, as 24, is pivotally mounted on the upper surface of the base II by a pin 25 which extends through the base H and through one end of the arm 24. The end of the arm 24 is spaced upwardly from the base member H by a suitable washer or spacer 26 about the pin 25. The forward end of the arm 24 is bent upwardly substantially at right angles to the length of the arm 24, as clearly shown in Figure 1 of the drawings. The clamping member 22 is adapted. to be pivotally mounted on the upper end of the upwardlyextending portion 21 at the forward end of the arm 24.

The clamping member 22 is formed in substantially the same manner as the clamping member l2 described above. The clamping member 22 is formed with a pair of spring-pressed, clamping

jaws

28 and 29 carried by a split ring or tubular member 30.

The arms 3.1.and32 formed integrally Withthe jaw members 23 and 29', respectively, are adapted to engage through slots intermediate the length of the sleeve 39 opposite from the split edges. The

handles SI and 32 are substantially pivoted in the slots in the tube 39, whereby upon rocking movement of the handles 9| and 32fdivergingly together, the jaw members 28 and 29.are moved divergingly apart for receiving therebetween the sharpening element E. A pivot pin, as; 34, is loosely engaged between the

jaw members

28 and 29 at one end thereof. The pin is so engaged between the jaws 28 and 29-that the jaws may be moved. apart when it is desired to clamp the sharpening element E therebetween, the engagement of the pin 36in the

jaws

29 and 29 being such .that the free movement of the jaw members may be effected by pressing on the handles 3| and 32. The pin 34 is secured on the upper end of the. free. end portion 27 of the armv 2-2.

In the use and operationof the scissor-sharpening tool It, described above, a blade B of, the scissors to be sharpened is clamped between the jaws l lLandv |-0f the clamping member i2. The cutting edge of the blade B is disposed above the surface of the supporting plate 5!. A suitable rubber bead or cushion, as 36, iscarriedby the clamping member [2 between one of the jaw members, as 15, and the surface of the blade B. The cushioning member 35 provides for the application of a clamping force alongthe length of the blade B between the jaws of the clamping member, and provides for a uniform force to be applied along the entire area of the blade B clamped in the member I2.

A sharpening element E, which may be of carborundum, or other suitable abrasive material, is adapted to be resiliently clamped between. the jaws28 and 29 of the clamping member 22. The sharpening element E is secured between the

jawmembers

28 and 29 by the force of the resilient sleeve or tube 39. As the sharpening element E1 is only resiliently secured between the clamping members 28 and- 29, it may be adjusted to any desired position along the length of the-jaw mem-. bers, andthe angular relation between. the jaw members and the sharpening element may be suitably adjusted as desired. In this manner, the sharpening element E may be supported for en.- gaging .the cutting edge of the blade B at any desired angle. For removing or adjusting. the sharpening element E, the clamp 22..may be pivoted upwardly about the pivot-pin .34 sothat the. sharpening element E may be positioned between the

jaws

28 and 29 free from any obstructionof the base ll.

When the scissor blade B is positioned in the clamp 12, and the sharpening element E is secured in the clamp 22 as desired, the clamp 22 is pivoted downwardly about the pin 34 so that the sharpening element E' will engage the cutting edge of the blade B. The operator may then grasp the handles 3| and 32 and rock the clamping member 22 about the pivot 25, which secures the arm 2 to the base 5 Rocking of the clampingmember 22 and the. sharpening element E about the pivot 25 will provide for the movement of the sharpening element E along the length of the cutting edge of the blade "5 to provide for the desired sharpening of the blade.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all.variations falling within the purview of the appended claim.

Having thus described my invention, I claim:

A scissors sharpening device comprising a fiat basemernber, a spring pressed clamping member fixed on one edgeof saidbase member for securing a scissors blade tobe sharpened, said clamping member being provided with a rubber cushion member which serves to insure the application of a uniform force over theentire area of a scissors blade held in said clamping member, anarm pivoted at one end thereof on said base member for pivotal movement only ina plane parallel to the plane of said base member,. a second spring,

pressed clamping member including a pair of separable jaws, a pivot pin on said arm loosely extending-through said jaws for securing said second clamping member on said arm for pivotal movement thereon in a plane at right angles to the plane of said base, anda sharpening element supported in said second clamping member for engagement with said blade to be sharpened.
