WH ETSTONE FOR ANlMALfCLIPPERS.

SPECIFICATION forming part of Letters Patent No. 432,431, dated July 15, 1890.

' Application iiled January 3 1890. Serial No. 335,817. (No model.)

T0 all whom it may concern:

Be it known that I, CHESTER M. PALMER, of Lamartine, in the county of Fond du Lac and State of Wisconsin, have invented a new and useful Improvement in "Whetstones for Animal-Clippers, ofv which the following is a specication.

The object of my invention is to provide an improved Whetstone for sharpening in an even and expeditious manner the V-shaped cutting-edges of the knife of such implements as horse-clippers and sheep-shears Without removing the knife from the finger-bars.

It-consistsin a multiple Whetstone arranged as a series of parallelbars in asuitable frame or bed, the body of the stones having an inclination to one side of a vertical line and the whole bed being mounted pivotally, so as to be reversed to reverse the inclination of the stones when the opposite sides of the V- shaped edges of the knife are to be sharpened, as hereinafter fully described.

Figure 1 is aview in perspective of the whetstone, and Fig. 2 is a vertical cross-section of the same.

A represents a stationary base-plate, upon which is pivotally mounted at a the Whetstone-bed B, which has a raised flange b around its margin.

C are the Whetstone-bars, which are arranged parallel with each other a uniform distance apart, which distance corresponds to the spacings of the V-shaped teeth-of the knife. These stones are immovably ixed Within the bed B, and are set at an inclination to the vertical, so as to leave their sides c easily accessible for Whetting purposes. The opposite sides of these stones are never brought into action.

In making use of my invention the cutter of a horse-clipping or sheep-shearing tooll is applied directly to the Whetstone Without disconnecting vthe finger-bar from the knife, as shown in dotted lines, and one edge of each V-shaped blade is applied to a face c of its corresponding Whetstone. The cutter is then gently pressed against the stone and is reciprocated to sharpen one side of each V-shaped blade. This being accomplished, the whetstone-bed B is turned upon its pivot ct one hundred and eighty degrees, which exactly reverses the inclination of the wheistone-` bars, as shown in dotted lines. The opposite sides of the cutter-knives are now applied to the reversed Whetstone-bars and are sharpened in a similar manner.

Having thus described my invention, what I claim ,as new isl. A multiple Whetstone consisting of a series of sharpening-bars mounted upon and combined with a reversible bed, substantially as shown and described.

2. A multiple whetstone consisting of a series of sharpening-bars inclined to the vertical and arranged parallel With each other, combined with and fixed in a pivotal or reversible bed, and a base-plate sustaining the pivotal bed, substantially as shown and described.

The above specification of my invention signed by me in the presence of two subscribing Witnesses.

CHESTER M. PALMER.
