IMPROVEMENT IN HARVESTER-CUTTER HOLDERS.

To all whom, fit 'may concern:

Be it known that I, SILAS H. WILSON, of the city7 of Auburn, in the State of New York, have invented a new anduseful device for holding the sickle-bars or knives of reapers and mowers in grinding, which I call A Harvester-Cutter Holder; and l do hereby declare that the following isa full, clear, and exact description of the construction and operation of the saine, reference being had to the annexed drawings, making part of this specication, in which- Figure l is a perspective view of one of the holders as applied to the cutte'rs, and

Figure 2 is a vertical section through its centre', showing the arrangement of the several parts.

The same letters in each ligure indicate like parts of the device.

In sharpening the cutters of'harvesting-machines,'

great difliculty isexperienced in holding them properly to the stone, their form being such that they cannot be conveniently held in the hands, and danger of injury to the hands always attends the operation, together with annoyance from the tilt-hy wate'r flowing from the grindstone over the hands.

To overcome these difficulties and objections is the object of the invention; and

It consists in the application of adjustable handles to the cutters or sickle-bars of harvesters, so that the Operator can firmly and safely hold the same for the purpose of sharpening or grinding.

A represents the l'iandle-part of the device, which may be lmade of metal, of any convenient form, anc hollow, to give it lightness.

The lower end of the handle is spread ont, so as to forni lips, B, at right angles to it, or the lips may be made separate from the handle-part, in the form oi' a bung-washer.

A spindle or bolt, G, having an elongated thin head or washer, D, at one end, and a screw-thread formed on its other end, is inserted in the handle-piece A, and a thumb-nut, 1G, is placed on the screw F of the spindle G.

When thus arranged, by turning the thumb-nut E, the head l) will be drawn towards the lips B, so that anything placed between the parts B and D will be fastened and held as in.a vise.

By placing the parts B and l) on contiguous blades of the sickle, as in iig. 1, and turning the thumb-nut E down snug, the holder is rigidly fixed to the sicklebar. Another similaiholder, being fastened to the other blades ai' convenient distance, enables the operator to seize and hold the sickle, with both hands, rinly to the grindstone, so ,as to sharpen it perfectly, with safety and rapidity.

A thinible or collar, of soft metal, G, may be placed.

on the spindle C, to protect the edges of the cutters from injury when adjusting the handles, two of which, one for each hand, should be attached to the sickle or knife-bar.

It is evident that various modifications of the device and its application may he made, without changing the character of the invention.

What I claiin as new, and desire to secure by Letters Patent, isp The -adjustable handlesior holding reaper-knives to the grindstone in sharpening, arranged and applied substantially as set forth.
