Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed November 12, 1913. Serial No. 800,545.

T alien/1.0m it may concern Be it known that I, JOSEPH WALKER, residing at Niagara Falls, in the county of Niagara and State of New York, have mvented certain new and useful Improvements in Knife-Sharpeners, of which the following is a specification.

My invention relates to certain new and useful improvements in implements for use in sharpening knives and the invention has primarily for its object to provide a slmple and inexpensive construction, in which the parts are so designed that the sharpenmg member may be folded down out of the way when not in use, so as not to project greatly above the table top and interfere with the free use of the table, or other support on which the device is secured.

Generically, the invention provides a base which is adapted to be screwed down or otherwise secured to a table or other support, and a sharpening member which is hinged to the base in such a manner as to be susceptible of being folded down out of the way when the device is not in use, the sharpening member including an integral body having a V-shaped notch provided with sharpening edges and an integrally formed strip in which the sharpening steel member is held, the sharpening steel projecting up in alinement with the V-shaped notch so as to present two sharpening sides to the device.

In its more subordinate nature, the invention comprises novel details of construction, combination and arrangement of parts, all of which will be first fully described in detail, and be specifically pointed out in the appended claims, reference being had to the accompanying drawing, in which:

Figure 1 is a perspective view showing the invention in use. Fig. 2 is a similar view showing it folded down out of use. Fig. 3 is a vertical cross section on the line 3-3 of Fig. 2.

In the drawing, in which like numerals and letters of reference indicate like parts in all of the figures, 1 is the base which is provided with screw holes 2, through which the securing screws 3 are adapted to be passed to hold the device down on the table or other support on which it is mounted.

The base 1 is provided with a hinged section 4 and adjacent thereto it is provided with ears 5 that are stamped up or bent up out of the base 1 to form stops against which the sharpening section proper 6 is adapted to engage when swung up into its operative position, as shown in Fig. 1.

The sharpening section 6 is composed of a thin metal plate that is provided with a hinged portion 7, by means of which it is hinged to the hinged portion 4 of the base 1, and it also includes the bifurcated upper end to form fingers, each of which has a sharpening edge 8, the sharpening edges 8 being opposed and thereby forming a V-shaped notch 9.

The plate 6 is provided with a strip 10 that is stamped out of the same and bent to form a holding device for the removable sharpening steel 11, the steel 11 having sharpening edges 1212 to cooperate with the edges 88 and thus form two sharpening channels in which the knife is drawn to effect the sharpening act.

When the device is to be used the member 6 is swung up from the position shown in Fig. 2 to the position shown in Fig. 1, and by reason of the provision of the lugs 5 and the location of the sharpening edges 12 and 8 (such sharpening edges being beveled whereby the sharpening act is effected, as indicated in Fig. 1) the act of drawing the knife through the sharpener will hold the member 6 up in its vertical position against the lugs 5. When it is not desired to use the sharpener, the operator simply swings the member 6 down to the position shown in Fig. 2, when it will be out of the way. The lugs 5, it will be noticed, are so designed that when the member 6 is swung down out of the way, they will not be of any greater height than the hinge joint whereby the lugs 5 are protected by the hinge joint, as it were, from injury or from themselves injuring the hand of the user or anyone using the table or other support on which the device is fastened.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily apparent to those skilled in the art.

What I claim is 1. A knife sharpener comprising a base plate adapted to be secured to a suitable support, said base plate having an eye turned up at one edge to form one part of a hinged member and having lugs turned up at the sides to form stops, a sharpener plate having eye portions to aline with the eye of said base plate and a hinge pin passing through said eyes, said sharpener plate including a sharpener edge, and a sharpener steel carried by said plate to operate with said sharpener edge, all being arranged whereby, as the knife to be sharpened is drawn over said sharpener plate in one direction, ening plate will be held up against said lugs, said lugs being spaced slightly back from the hinge whereby to tilt said sharpening plate slightly rearwardly against said lugs thereby to throw the center of gravity of said sharpening plate to the rear of said hinge when said sharpening plate is projected upwardly in its operative position,

said sharpening plate adapted to-swing' down along the edge of the support and below the plane of said base plate when not in use.

2. In a knife sharpener, the combination with a flat support having an edge, a base plate secured to the top of said support and said sharp-.

having one edge arranged adjacentto the edge of said support, said plate having a hinge eye at the support adjacent edge and upwardly projected lugs spaced inwardly from the support adjacent edge, a sharpening-plate having hinge eyes, and a hinge pin connecting said sharpening plate eyes with said base plate eye whereby when said base plate is swung upwardly above the plane of said support, it will rest against said stops in a position tilted slightly backwardly from the vertical plane of the edge of the support to rest against said stops and whereby when said sharpening plate is swung downwardly it will lie against the edge of said support and below the upper horizontal surface of the support, said sharpening plate including sharpening elernents.
