TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it kil/own that I, CHESTER F. DEAN,` of St. Johnsbury, in the county of Caledonia, and State of Vermont, have invented a new and useful Knife-Cleaning Machine; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a. side elevation,

Figure 2 a front view, and

Figure 3 a. vertical andlongitudinal section, and

Figure 4 a top view of'it. v,

In such drawings,A denotes an oblong box, open at one end, and there provided with a slide, B, to slide vertically into grooves s s formed at or near such end. t or nen'r the lower part of such end is an India-rubber cylinder, a, covered with a. p iece of leather,.11, the same constituting an elastic lip. Directly over the said India-rubber cylinder is another such cylinder, c, on which rests one end of a thin board or presser, C, which extends into the box to its rear, and has a. width corresponding to 0r about to'that of the interior of the box. A strip of leather, d, fastened to the board C, is carried underneath and about the cylinder c, und extends upward into the grboves s s in which the slide B is placed',` such slide heilig to hold the leather in place. The cylinder c and piece ot`,le:ttlier d constitute another elastic lip. There is a block or spring, D, of India rubber, ixed on the top of the board C. A screw, E, screwed-through the top of the box A, bears at its lower end against the upper surface of such spring. `A. clamp, I", formed Aand furnished with a screw, Cr, as shown in the drawings, may be projected from the bottom of the box A, such serving to clamp the box to a table or bench. rThe box, when in use, is to have emery or other suitable powdered polishing or cleaning material within the space between the boord C and the bottom of the box.

5 In order to clean a knife, it is to be introduced between the elastic lips of the mouth of the box, and pushed l \/forsa-rd and drawn backward several times within the mass of emery. The presser or board C will close the said mass throughout its extent upon the knifc,'the spring D allowing the mass to separate, as occasion may require, in order to admit the knife. The screw E serveslto force the presser down upon the mass of einery in the box. In my knife-cleaner, a knife is cleaned by the massief emery in the box, and not by the elastic lips of the mouth of the box, they being simply to keep the cleaning material within, and allow the knife a passage into the box. A

I do not claim a. knife-cleaner or bex haring a, mouth and elastic lips thereto, provided with leather coverings to effect cleaning ofthe knife.

What I claim as my invention, is

The combination and arrangement of the presser C and its screw E with the box A and its elastic lips, substantially as described.

I also claim the combination of the spring D with the presser C, its screw E, and the box A, having elastic lips as described.

I also claim the combination of the slide D and the grooves s s with the box A, the presser C, and its strip et' leather d, applied to an India-rubber cylinder, c, or its equivalent, the whole being substantially as specified.

CHESTER F. DEAN.
