Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed December 6. 1905. Serial No. 290.615. Renewed July 2. 1967. Serial No. 381L927- To all whom it may concern:

Be it known that I, JACOB WissLER, citizen of the United States, residing at Lyndburst, in the county of Augusta and State of Virginia, have invented new and useful Improvements in Disk-Sharpeners, of which the following is a specification.

This invention has relation to disk sharpeners and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide an attachment for disk implements such as barrows, plows, cultivators or drills, said attachment being so arranged as to hold an abrading material in contact with the edge of the disk as the same rotates in working the soil; such. frictional cont-act between the disk and the abrading material sharpens the disk while it is working. This arrangement saves a great deal of time and annoyance in keeping the disk edges in proper condition as the sharpening is done automatically.

One form of the invention provides a rotating abrading material geared with the disk shaft. The rotating abradmg material rotates in the opposite direction from that of the disk consequently the process of sharpening is facilitated.

l/Vhen one disk issufficiently sharpened the sharpening device may be shifted to another disk and when all are sharpened the sharpening device may be so located as not to be in contact with any disk but at the same time is connected with the implement.

- In the accompanying drawing :Figure 1, is a side elevation of a disk showing a rotating sharpener applied thereto. Fig. 2, is an edge elevation of the rotating sharpener as shown in Fig. 1, and shbwing several disks in section. showing a sharpener applied thereto. Fig. 4, is an end elevation of the sharpener as shown in Fig. 3, and showing several disks in section, and Fig. 5, is a perspective view of the shoe for holding the abrading material as shown in Figs. 3, and 4.

In the form of the invention as shown in Figs. 1, and 2, the disks 1, are mounte upon the disk shaft 2, in the usual manner. The rod 3, is suitably supported upon the frame work of-the implementand extends parallel with the shaft 2.

Fig. 3, is a side elevation of a disk The abrading wheel 4, is loosely journaled vupon the rod 3, and is held in proper position .upon the said rod by the collars 5, 5, which The are also located upon the said rod.

wheel 4,is provided on one side with a sprocket wheel 6, and the sprocket wheel 7, is fixed upon the shaft The sprocket chain 8,.surrounds the wheels 6, and 7. The edge of the wheel 4, is in contact with the edge of one of the disks 1. As the disk 1, rotates the shaft 2, also rotates and through the s rocket wheel 7, chain 8, and s.rocket Wheel 6, rotary motion is transinitte to the wheel 4. The Wheel 4, rotates in the opposite direction from that of the disk 1, and the edge of the said disk is sharpened. The sprocket wheel 7, is made in sections which are bolted to ether as shown in Fig. 1. When one dis 1, is sufficiently sharpened the wheel 7 ,is removed from the shaft 2, and is placed adjacent another disk 1. The wheel 4, is shifted along the rod 3, until its edge is in contactwith the last said disk and is then secured by setting the collars 5, 5, I

' and is held in place thereon by the set screw 10. The fiat spring 11, is attached at one end to the said collar 9. The shoe 1;, is at tached to the other end of the said flatspring 11, and within the said shoe 12, the abrading block 13, is secured. The said block bears against the edge of the disk 1, and sharpens the same as it rotates. The abrading material in either instance may be emery, stone or any other suitable grit.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. -In combination with a disk implement a disk sharpener consisting of a flat spring attached at one end to the implement, an abrading material attached to the other end of said spring and held in contact with the edge of the disk as itrotates while working a disk sharpener consisting of a fiat spring attached at one end to the implement a shoeattached to the other end of said spring, an

7 ing against the edge of the disk as it rotates while Working the ground.

3. In combination with a disk implement a disk sharpener consisting of a flat spring having at one end a collar by means of which it may be adjnstably attached to the implement, an abrading material attached to the other end of said spring-and held in contact with the edge-of the disk as it rotates While Working the ground.

4. In combination Witha disk implement a disk sharpener consisting of a fiat spring having at one end a collar by means of iivhich it may be adjustably attached to the imple- 15 ment, a shoe attached to the other end of said spring, an abrading material held in said shoe and bearing against the edge of the disk as it rotates While Working the ground.

In testimony whereof I affix my signature, 20 in presence of two subscribing Witnesses.

JACOB WISSLER.
