Feb. 12, 1952 J. BROCKLEY SCISSOR SHARPENER Filed Oct. 5, 1950 INVENTOR co & firocialey ATTORNEYS Patented Feb. 12, 1952 UNITED STATES PATENT OFFICE 2,585,623 sorsson SHARPENER Jacob Brockley, Newport News, Va.

Application October 5, 1950', Serial No. 188,584

This invention relates to a scissor sharpener and is an improvement over the construction embodied in my copending application Serial No. 57,247, filed October 29, 1948, now abandoned, for Scissor Sharpener.

An object of this invention is to provide a scissor sharpener which embodies a frame having an abrading wheel mounted thereon with a ledge or shelf for supporting a scissor blade whereby the blade may be drawn laterally across the wheel.

Another object of this invention is to provide an improved securing pin for the abrading wheel which will facilitate assembly, and reduce production costs.

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.

upright plate H which is braced by means of a right angularly disposed bracing web l2. The plate H has extending downwardly therefrom a T-shaped shank l3 and the shank I 3 terminates at its lower end in a laterally projecting boss l4 through which a clamping screw l5 threadably engages. A fixed clamping jaw or plate l6 extends right angularly from the lower end of the vertical plate H, and a pair of vertical flanges I! extend from the plate II and also from the jaw or plate IS.

A pair of horizontally disposed ledges or shelf members [8 extend outwardly from the flanges H and provide a supporting means for supporting the flat inner side of a scissor blade when the blade is being sharpened. An abrading wheel I9 is secured to the upper end of the frame Ill and the latter is formed with a boss having an opening 2|. 22 extends through the center of the abrading wheel l9 and is pressed into the opening 2|.

A spider shaped resilient washer 23 is interposed between the head of the pin 22 and the adjacent side of the wheel 19. Preferably a A headed wheel securing pin' 1 Claim. (Cl. 51-156) washer 24 is interposed between the radial and resilientarms 25 of the resilient washer 23 and the inner side of wheel IS. A washer 26 is also interposed between the rear side of the abrading wheel l9 and the forward side of the plate H. The resilient washer 23 provides a means whereby the abrading wheel will normally and resiliently be held against rotation, but may be forcibly rotated so as to present to the blade a clean and unridged or grooved peripheral surface. The flanges H with the plate or jaw member l6 provide a pocket or receptacle 2! wherein the grindings are adapted to be caught.

The two washers 24 and 26 provide a means whereby the wheel I!) may be held under constant pressure from resilient washer 23 and wheel I!) may be manually turned without cutting the arms 25 of washer 23.

In the use of this device the frame I0 is clamped to an edge of a support by means of a clamping screw l5 and the jaw 16. The two blades of the scissors are opened, and one blade is laid flat on the ledge or supporting member IS with the cutting edge of the blade confronting the periphery of the abrading wheel l9. The cutting edge of the blade is then pressed against the wheel 19 and drawn across the wheel from one end of the blade to the other. This operation is repeated until a relatively keen edge is formed on the scissor blades.

By providing a sharpener as hereinbefore described and particularly the improved abrading wheel supporting pin the assembly of the device is greatly facilitated as the pin 22 is secured in the boss 20 by'means of a press fit. This securing of the pin 22 is such as to place the resilient washer or spider 23 under sufiicient tension to frictionally hold the abrading wheel l9 against free rotation.

In order to prevent the formation of transverse grooves in the wheel face, which might result from repeated engagement of a scissors blade with the wheel held in one position, and to preserve a smooth ungrooved wheel face, the wheel may be partially turned during the sharpening operation.

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.

What is claimed is:

A scissor blade sharpener, comprising a base having a horizontally disposed fixed member of substantially rectangular form, clamp means dependently carried by said base, an upright member having a bore therein disposed at one side of said base, said upright having oppositely disposed side extensions attached to one side of said base, a pair of spaced vertical walls ailixed to said base and disposed at right angles to said side extensions to form an open-top receptacle extending at right angles to,said upright, said vertical side walls having their top edges formed as oppositely extending right angularly disposed flanges lying in the same horizontal plane, a transverse support member having a head force fitted in said bore of said upright in overhang- I ing relation to said receptacle, an abrasive wheel having a recess in one face thereof rotatably carried by said support and extending into said receptacle between said spaced flanges for engagement by a scissor blade supported by either 1 4 tion plate to frictionally restrain said wheel against free rotation.
