SHARPENER FOR HAIR-CLIPPERS Specification of Iaetters Patent.

Patented June 1, 19 15.

Application filed January 12, 1915. Serial No. 1,825.

To all whom it may concern.

Be it known that I, WILLIAM G.'AoKnR- MAN, a citizen of the United States, residing at lVestpoint, in the county of Cuming and State of Nebraska, have invented certain new and useful Improvements in Sharpeners for Hair-Clippers; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device -for sharpening the blades used in hair clippers, and the primary object of the invention is to provide a sharpening device which will efficiently sharpen the blades used in a hair clip by the application of a whetting or sharpening stone to the surface of the blades which engage each other, for evenly sharpening the entire surfaces of the blades for insuring the eflicient cutting operation thereof.

Another object of this invention is to pro vide a sharpener as specified which embodies a reciprocably movable sharpening stone, means for reciprocating the stone and for holding the clipper blade firmly upon the upper surface of the sharpeningstone during the reciprocatory movement of the stone for efficiently sharpening the blade.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved sharpener, Fig, 2 is a top plan view of the sharpener showing parts thereof broken away, Fig. 3 is a vertical cross sectional view through the sharpener, Fig. 4 is a fragmentary top plan view of thesharpener, Fig. 5 1s a fragmentary vertical sectional view through the sharpener, and Fig. 6 is a detail bottom perspective view of the clipper blade holding plate.

Referring more particularly to the drawings, 1 designates the supporting base of the sharpener, which hasa vertical board 2 secured to the upper surface at one end thereof, which board rotatably carries shafts 3 and 4. The shaft 3 has a hand wheel 5 mounted thereupon, and also a gear 6 which gear is rotated by the manual rotation of the hand wheel 5. The gear 6 meshes with a plnlon 7 carried by the shaft 4, for rotating the shaft 4 by the rotation of the hand wheel and the shaft 3. The shaft 4 has a disk 8 mounted thereupon, to which disk is eccentrically connected a pitman rod 9. The pitman rod 9 extends longitudinally along the upper surface of the supporting base 1,

being spaced upwardly therefrom, and has its rear end connected to a slidable block 10. The block 10 is slidably mounted upon the plates 11 and 12, which plates are carried by suitable supporting legs 13'. The legs 13 are, in any way. desired, connected to the supporting base 1 and extend upwardly therefrom, as is clearly shown in Fig. 1 of the drawing. The plates 11 and 12 have their facing inner edges spaced from each other for forming a guideway in which is seated the lug 13. The lug 13 is formed upon and depends from the under surface of the slidable block 10, and it guides the re ciprocatory movement of the block, preventing the same from moving laterally during its longitudinal reciprocatory movement. The block 10 also has a bolt 14 inserted therethrough, which extends through the opening 15 formed by the spacing of the inner side edges of the plates 11 and 12. The bolt 14 has a plate 15 secured to its under surface and held in slidable abutting engagement with the under surfaces of the plates 11 and 12 by a nut 16 which is mountupon the end of the bolt. The plate 15 is provided for preventing vertical displaceduring the 20 and 21 into'engagement with the sides of a sharpening stone 23, for holding the stone attached to the block 10 for slidable movement therewith.

The supporting structure or base 1 has a standard 24 secured thereto, which standard has an arm 25 pivotally connectd to its upper end. The arm 25 has its outer end reduced and provided with a plurality of siwith a slot 30 formed in the upper face notches 26, for receiving a ring 27 which is carried by a weight 28. The arm 25 has positioned therebeneath, a clipper blade engaging plate 29, which plate is provided structlon.

.Q Inthe o eration of the improved sharpcner heretofore described; the clipper blade to be sharpened, is placed upon the plate 29, after which thelever or arm 25 is moved so that it will assume a horizontal positionfand cause the under surface of the blade, which 1 is to be sharpened to rest upon the upper surface of the sharpening stone 23. The weight 28 which is hung upon the outer end of the arm 25 will tend to force the blade against the upper surface of the stone for insuring the sharpening of the same upon the reciprocatbrymovement of the stone. The stone 23 is reciprocated, by the rotation of the hand wheel 5 which will rotate the shaft 4. through the meshing engagement of the gear 6 and the pinion 7. The rotation of the shaft 4, will owing to the eccentric connection between the piston rod 9 and the disk 8 reciprocate the supporting block 10 and the whetting or sharpening stone 23, for sharpening the blade 32 of the clipper.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and ,of the method of operation of the improved sharpener for hair clippers will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination andarrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.

What is claimed is 1. In a device for sharpening clipper blades, a supporting structure, a pair of horizontally disposed plates carried by said supporting structure and having their fac- W "ing sides spaced from each other, a block slidably' mountedtupon said plates, means for preventing vertical and lateral movement of said block, a sharpening stone detachably carried by said block, and-means for holding a clipper blade in engagement with the upper surface of said sharpening stone, and means for moving said sharpenmg stone'forwardly and rearwardly upon said supporting structure for sharpening said blade.

2. In a device for sharpening clipper blades, a supporting structure,ya pair of -plates supported by said supporting structure and upwardly therefrom, in a horizontal plane, said plates having their facing sides spaced from each other, a block slidably mounted upon said plates, a depending lug formed upon said block and between the facing sides of said plates for preventing the lateral movement thereof, means for preventing vertical movement of said slot, at sharpening stone detachably carried by said slot, a standard secured to said supporting structure, an arm pivotally connected to said standard, a plate having a clipper blade detachably attached thereto, said plate having a longitudinal groove formed in the upper face thereof for receiving the lower edge of said arm for holding said clipper blade in engagement with the upper surface of said sharpening stone, and means for moving said sharpening stone forwardly and rearwardly upon said plate for sharpening said cutter blade.

3. In a device for sharpening clipper blades, a supporting structure, a pair of horizontally disposed plates supported by said supporting structure and upwardly therefrom, said plates having their facing sides spaced from each other, a block slidably mounted upon said plates, a pair of upstanding plates carried bysaid block and provided for gripping the side edges of the sharpening stone, means for tightening the grip of said plates upon the sharpening stone, a standard carried by said supporting structure, an arm'pivotally carried by said standard, a plate for detachably supporting a clipper blade, said plate being provided with a longitudinal groove for receiving the lower edge of said arm for holding said clipper blade upon the upper surface .of said sharpening stone, a pitman rod connected to said block and means for reciprocating said pitman rod for moving said block longitudinally upon said plate for sharpening the under surface of said stone, and means for preventing vertical and lateral movement of said block and said stone.

In testimony whereof I afiix my signature in presence of two witnesses.
