IMPROVED KNIFE-SHARPENER. l f.

faQ- Beit'known that I, THOMAS HAYNES, of the city and. county of St. Louis, State of Missouri, have invente anew anduseful machine forrSharpening Knives, Scissors, and other articles ofl cutlery; and I do hereby declare that the following is a true, full, clear, and exact description of the* construction :and operation of the same, reference Vbeing had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view.` v

Figure 2 is a lateral section. i

Letters A and B, fig. 1, are perpendicular columns, firmly secured to or cast with the broad base C. D, E, and F are quadrangular transverse bars, severally supported by the columns A andl'B. G; H, and I arr thumb-screws penetrating in the columns A and B to the aperturesirnade to receive the ends of bars D, E, and F. K, L, and M, fig. 2, are the ends of the transverse bars D, E, and F, and lare'supported by columns A and B. N is a slot in the columns A and B. P is the handle to transverse bar D., 5 O is a. pivot, upon which the end of bar'D turns, andQ Q are clamps, with aperture for screws. l p

To enable others to make and use the mach-ine, I will proceed to describe its construction and operation.

The columns A B, the base C, and'alsothe transverse bars D and F maybe made of iron or other metal. The middle bar E should be madepof hardened steel. The manner of construction is as follows V- The columns should be made so as to admit the arrangementof'the three transverse bars D, E, and F, as

-follows, viz: The end of the barD, fig. 1, rests within the slotN, fig. 2, and is secured by and works upon the pivot 0,'g. Theiother end of said bar D passes through slot N, iig. 1, in column A,jand terminates in the handle l?. y means `of this handle the end of bar D, to which it^belongs and is a part, can be elevatedfor depressedv atpleasure, and then secured in the desired position by the thumb-screw G. The bar E rests `upon the columns A and B, and can be placed in position or removed at pleasure, by passing it through'an aperture corresponding in size, as sho-wn by letter L in fig. 2. This'bar may be rmly secured by thnmb-screw H. When in position its angular edges are parallel with, and in close proximity with, the upper and ,lower bars lD and F. Said bar E may be constructed in a triangular, quadrangular, sexangular, octagonal, or any other angular form, and placed so that one ofits angular edges may be used. The lower bar F, fig. 1, is also supported by columns A and B. The end resting in column B is in a slot, so that iteun be elevated or depressed and secured in the position desired by-thumh-screw I. Y

The manner in which the machine is operated is as follows: The knife or other larticle to be sharpened is passedV between the bars D E or F E; the edge of the knife or blade is pressed upon the angular edge of the middle bar E, whilst the edge of the back at the same presses upon the bars D or F. 'lhe space between the bars D and E and F and E may be lessened or enlarged at pleasure bynieans of the thumb-screws Gr and I. The knife or other article to be sharpened is then drawn backwards and forwards, and its edge is soon evenly sharpened by contactwith the hard angular edges of the bar E.`

What I claim, as my invention, is- The arrangement and application of the angular steel bar E, in connection with the bars D and F, in the manner herenbei'ore described, for the purpose herein set forth.

' THOMAS HAYNES.
