Mown GUARD SHABPBNBB. A PTLIOATIOK :FILED IAE. 18, 1908. 4 914,914. Patented Mar. 9, 1909.
UNITED STATES PATENT FETS.I
CHARLES BATKE AND GEORGE F. BATKE, OF FERRY POINT, ALBERTA, CANADA.
MOWER-GUARD SHARPENER.
To all whom it 'may concern:
Be it known that we, CHARLES BATKE and GEORGE E. BATKE, subjects of the King of Great Britain, residing at Ferry Point, Alberta, Canada, have invented certain new and useful Improvements in Mower-Guard Sharpeners, of which the following is a speciiication.
When attempting to operate upon old or wet grass with a mower or binder considerable annoyance is commonly occasioned when the guards are blunt owing to the fact that the said guards have a tendency to drag the grass and the machine becomes clogged.
The object of the present invention has been to obviate this difliculty by the provision of a simple and inexpensive device by means of which the guards can be quickly and efficiently sharpened.
For a full description of .the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:
Figure l is a perspective view Of a sharpener embodying the invention. Fig. 2 is a longitudinal sectional view through the same. Eig. 3 is an end view looking directly into the socket. Fig. 4 is a transverse sectional view on the line 4 4 of Fig. 2.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawings, the numeral l designates the stock of the device which is provided at one end with a socket 2 and is designed to be rotated axially with respect to the socket, the said socket being provided with cooperating abrading surfaces for sharpening the guard which is received therein. In the present instance one end of the stock 1 is tapered to form a shank and terminates in an angular head 3 adapted to be engaged by a brace or similar tool for rotating the device. The socket 2 is V-shaped in section and is formed with the oppositely inclined walls 4 which intersect in alinement with the longitudinal axis ofthe stock. A removable plate 5 is fitted over each ofthe oppositely inclined walls 4, the edges of the plates being received within the grooves or guide Ways 6 formed in the ends of the socket. These plates 5 are in Specification of Letters Patent.
Application led March 18, 1908.
Patented March 9, 1909.
Serial No. 421,871.
the nature of files and have both faces thereof roughened, the plates being reversed when one of the roughened surfaces becomes worn. For the purpose of retaining the removable plates 5 in position within the socket 2 against accidental displacement, a cap 7 is utilized, the said cap being shown as threaded upon the exterior of the stock and formed with an annular flange S which projects over the end of the stock and overlaps the edges of the plates 5. It will thus be apparent that when the cap is in position the abrading plates 5 are held securely against displacement, while when the cap is removed the abrading plates can be reversed or replaced as desired.
Tn the operation of the device the angular head 3 at one end ofthe stock is engaged by a brace or similar tool and the socket 2 applied to the guard to be sharpened. The stock is then rotated through the medium of the brace whereupon the oppositely inclined abrading surfaces operate to sharpen the guard and produce a point thereon. .lt will thus be apparent that by means of this implement a ine point may be easily and quickly produced upon the guards of a mower, binder, or like machine.
Having thus described the invention, what is claimed as new is:
l. A sharpening device of the character described comprising a stock formed with a socket and designed to be rotated axially with respect to the socket, a removable plate fitted within the socket and provided with an abrading surface, and a cap for retaining the plate in position.
2. A sharpening device of the character described comprising a stock formed with a V-shaped socket and designed to be rotated axially with respect to the socket, removable plates fitted against the oppositely inclined walls of the V-shaped socket and formed with abrading surfaces, and a cap applied to the stock and formed with a iange engaging the plates to retain the same in position.
In testimony whereof we ai'i'ix our signatures in presence of two witnesses.
IsAAc POTTER.
