JOHN A. PEER, on BROOKLYN, NEW YORK, ASSIGNOR TO THE PEER MANU- FACTURING COMPANY, or SAME PLACE. I

KNIFE-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 465,880, dated December 29, 1891.

Application filed May 19, 1891. Serial No. 393,345. (No model.)

ful Improvement in Knife-Sharpeners, of

which the following is a specification.

The object of this improvement is to provide a simple, cheap, and efficient sharpener for table-knives and analogous devices.

' lo I will describe a knife-sharpener embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure 1 is a top View of a knife-sharpener embodying my I 5 improvement, with a certain part removed to exhibit other parts. Fig. 2 is a side view thereof. Fig. 3 is a central longitudinal section.

Similar letters of reference designate corresponding parts in all the figures.

A designates the base piece or frame.

.8 O designate blocks or pieces of material suitable for sharpening table-knives and like devices. They are arranged opposite to each other and are severally provided with a nu mher of projections or tongue-like portions 1) c,

which are inclined downwardly. The projections or tongue-like portions of each of these blocks orpiecesB O are arranged opposite the spaces between those of the other one of said 0 blocks or pieces, and it is intended that the blocks shall-be so set that the lower portions of the projections or ton gue-like portions of the two blocks shall overlap. Preferably the projections or tongue-like portions will be 3 5 rounded at their upper extremities.

The block B has its body or main portion fitted to a recess a, formed in the base piece or frame A and may be adjusted lengthwise thereon, and, when adjusted, fastened in 130-- sition by any suitable means-as, for example, by set-screws a, passing through the sides of thebase piece or frame and impinging against the sides of the block B.

From the body or main portion of the block 5 B a portion is offset so as to extend over the top of the base piece or frame A. The upper surface of this offset portion of the block B may be used as a hone.

The block C is fitted to a recess a formed in the base piece or frame A, and is adapted to slide lengthwise thereon. It is forced to block may be engaged with the screw.

ward the blockB by means of a spring D,and

it may be adjusted away from the block B by means of a screw E. As here shown, the screw is provided at its inner end with a head and the block 0 with a notch, whereby the 'l he screw is shown as extending through the adjacent end of the base piece or frame A and as having a nut 6 applied to it beyond the base piece or frame A. The springD is shown as surrounding the screw E between the block 0 and the opposite end of that recess in the base piece or frame A which is adjacent to the block 0. A cap-piece a is arranged over the recess of the base piece or frame, in which the block 0 works. It may be fastened in place by screws. 7

Obviously both the blocks may be removed at pleasure.

Obviously by manipulating the nut e the block 0 may be drawn away from the bloekB against the resistance of the spring D, and by turning the nut in the other direction the spring would be permitted to force the block 0 toward the block B. Obviously the block 0 is held in position in such manner as to be free to yield away from the block B. Owing to this, a knife or analogous device may be inserted between the upper portions of the pro ject-ions or tongue-like portions of the blocks B O,forced downwardly between the same, and moved back and forth while between them.

The base piece or frame may be made of any suitable material-es, for instance, metal* and the blocks B 0 maybe made of any material. Preferably their projections or tonguelike portions 11 0 will be made of emery, and the hone portion of the block B will be made of such material as is ordinarily employed for hones.

By my improvement I produce a very simple, cheap, and eificient sharpener for knives and like devices, in which one of two blocks will have a sliding movement relatively to the 5 other, so that the two blocks will be adaptable to a knife or like device inserted between them.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a sharpener for knives and like devices, the combination of a base piece or frame and two blocks having projections or tongue-like portions inclined downwardly and arranged so that the projections or tonguelike portions of each block will be opposite the spaces between those of the other, so that they may overlap the latter, and one of said blocks being constructed to slide along the base piece or frame toward and from the other block, substantially as specified.

2. In a sharpener for knives and like devices, the combination of a base piece or frame, two blocks having projections or tongue-like portions inclined downwardly and arranged so that the projections or tonguelike portions of each block will'be opposite the spaces between those of the other, so that they may overlap the latter, and one of said blocks being constructed to slide along the base piece or frame toward and from the other block, and a spring for adjusting the sliding block toward its fellow, substantially as specified.

3. In a sharpener for knives and like devices, the combination of a base piece or frame, two blocks having projections or tongue-like portions inclined downwardly and arranged so that the projections or tonguelike portions of each block will be opposite the spaces between thoseof the other, so that they may overlap the latter, and one of said blocks being constructed to slide along the base piece or frame toward and from the other block, a spring for adjusting the sliding block 4. In a sharpener for knives or like devices,

the combination of a base piece or frame having two recesses, a block having a body or main portion fitting in one of the recesses and an ofiset portion extending over the base piece or frame and forming a hone, and a sliding block arranged opposite to the block aforesaid, said blocks having projections or tonguelike portions which are inclined downwardly and so arranged that the proj ectionsortonguelike portions of each block will be opposite the spaces between those of the other block, substantially as specified.

5. In a sharpener for knives and like devices, the combination of a base piece or frame, two blocks having projections or tongue-like portions downwardly inclined and arranged so that those of each block will be opposite the spaces between those of the other block,a screw detachably connected with one of said blocks, and a spring for moving this block in one direction,substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN A. PEER.
