s. CAROSI 2,157,816 'DEY ICE FOR SHARPENING CUTLERY Filed Dec. 6, 1938 ATTORNEY Patented May 9, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to devices for sharpening scissors, barbers shears, and like cutlery instruments.

One of the objects of the invention is to provide an inexpensive device which is so simple to operate that scissors, barbers shears, and like instruments may be satisfactorily sharpened by a person unskilled in the art of sharpening cutlery.

Another object of the invention is to provide a device of the character mentioned which is adjustable to accommodate various sizes of instruments, and whose sharpening element is also adjustable angularly to conform to the angle of the bevel of the blade being sharpened.

Another object of the invention is to provide means whereby the sharpening file may be read ily removed and replaced when desired.

Other features, objects and advantages of the invention will appear from the following detailed description, wherein reference is made to the accompanying drawing, in which- Figure 1 is a perspective view of the invention; and-- Figure 2 is an enlarged detailed view in side elevation illustrating the file holder and the shear holder, parts being shown in section.

Referring to said drawing, the referencev numeral designates a base to which is attached the stationary jaw 2 of a vise. movable jaw 4 actuated forwardly and rearwardly by a hand wheel 5 in an obvious manner.

Also attached to the base and aligned with the vise is a pedestal block 6. Said block is provided with a plurality of vertical, spaced, aligned,

threaded bores into each of which is received a threaded pin 7, each pin having its upper end slotted, as shown at 8.

Fixed to the opposite edge of the base is a file holder 9, said holder being provided with a plurality of spaced and vertically aligned apertures lil. Located in one of the apertures I is a bolt the outer end of which is threaded to receive a wing nut I2 and the inner end of which is enlarged and terminates in a socket l3. Permanently received within the socket 3 is a ball l4 formed integrally on the end of a rod 25, this construction alfording a universal joint. Said rod 25 is telescopably received within a tube l5 carried by a handle 29, preferably made of wood. The pointed end of a file 2| is received by the handle 20 and projects outwardly therefrom, extending parallel with and at a spaced distance from the tube l5. An annular ring 22 is fixed to the tube I5 and maintains the free end of the file rigid and at a spaced distance from said tube.

To sharpen a pair of scissors, the finger loop of one of the blades of the scissors 23 is placed between the vise jaws 2 and 4, and the blade to be Said vise has a sharpened laid horizontally in the slot 8 of one or more of the pins 1. The vise is then tightened by rotation of the hand wheel 5 so that the blade is rigidly held in position.

The file 2| is then placed laterally against the blade and the angle of inclination of the file adjusted to correspond with the angle of the bevel of the cutting edge of the blade. When the file has been properly adjusted to the correct angle, the bolt H is placed in the appropriate aperture l0 and the wing nut i 2 placed on the bolt to retain the same in place and to maintain the file at the proper angle of inclination. The file 2| may then be manually reciprocated laterally along the beveled cutting edge for sharpening the latter.

It will be noted that during the reciprocating movement of the file, the rod 25 will telescope within the tube |5, thereby permitting such lat-- eral reciprocating movement, and, at the same time, maintaining the proper angle of the file.

After one blade has been sharpened, it may be removed from the device and the other blade inserted and the operation repeated for completing the sharpening of the scissors.

It may be pointed out that a plurality of aligned pins 1 are provided so that the device may accommodate blades of different lengths. Moreover, said pins are made vertically adjustable in their threaded bores so as to accommodate blades of difierent widths.

The file 2| may be, and preferably is, a common type of file, and may be readily replaced when necessary.

A longitudinally extending slot may be substituted in place of the spaced apertures Ii) of the file holder 9, if preferred.

What is claimed is In a device for sharpening cutlery, a vise for rigidly holding one end of the article to be sharpened, means for supporting the opposite blade end of said article, a. file for sharpening the cutting edge of said blade and adapted to be reciprocated laterally across the cutting edge, a handle, one end of said file being retained in said handle, a tube having one of its ends retained in said handle and projecting outwardly therefrom in substantially parallel relation above said file, a rod, said tube being telescopable on said rod, the free end of said rod terminating in a ball, a socket for embracing and retaining said ball, a rod supporting post, said socket being adapted to be supported in any of a plurality of vertically aligned apertures provided in said rod supporting post whereby the angle of inclination of said rod, tube and file with respect to the cutting edge of said blade may be adjusted.
