To all It'll 07]], it nu/y concern:

Be it known that I, OSCAR NORTON, a citizen of the United States, and a resident of Hartington, in the county of Cedar and State of Nebraska, have invented a new and Improved Holder for Sickle-Bars, of which the following is a full, clear, and exact description.

My invention relates to means for supporting such cutting members as the sickle-bars of reapers and mowers in proximity to a grinding-wheel to permit them to be properly sharpened. Its principal objects are to provide a simple and convenient holder for this purpose.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 shows one embodiment of my invention in side elevation in connection with a grinding-wheel, to which it is applied. Fig. 2 is an end elevation thereof looking from the left in Fig. 1. Fig. 3 is a top plan view, and Fig. at is a sectional detail showing the relation of the sickle-bar to the wheel.

A designates a supporting-frame including sidebars B, upon which are journaled a suitable grinding-wheel O, which, as illustrated, is driven by means-0f a crank D. Upon the side bars at each end are carried attaching devices, which may consist of bolts 10, having their heads adjacent to the frame, and nuts 11, operating upon their upwardly-extending ends. Upon the side of the frame opposite the crank the attaching devices may be retained in place by plates 12, having openings through which the bolts pass, these plates being in contact with the upper faces of the bars, which are provided with recesses to receive the bolt-heads. Upon the crank side brackets 13 are provided, which rise above the frame, so that the attaching devices are higher at this side.

Extending across the wheel-frame and carried by one of the pairs of attaching devices in a vertically-inclined position is a supporting-bar 1%, having a series of openings 15, here shown as four in number and so spaced that any two which are adjacent may receive the bolts 10. Upon the supporting-bar is mounted a frame F, which may consist of four carrier-bars, the outer being designated by the numerals 16 16 and the inner 17 17, these extending longitudinally of the wheel-frame and being connected by transverse bars 18 18 near the opposite extremities. The bars 16 are longer than their companions and are preferably bent at substantially right angles at 19 and then at 20 to surround the reduced cylindrical ends 21 of the supportingbar. This permits the carrier-frame to swing freely upon the supporting-bar and adjust itself to inequalities of the wheel during the sharpeningoperation. The portions 19 of the carrier-bars may be connected and the frame strengthened by a stay 22. Fixed upon the upper sides of the carrier-bars 17 17 near their center are cleats 23, spaced from the bars and having angular ends 24. which may be riveted thereto. In these cleats and in the bars beneath them may be formed series of alined openings 25, adapted to receive pins 26.

In use the supporting-bar beinginits central position upon the attaching devices, the bolts of which project through the inner openings, the barS which is to be sharpened is placed between the cleats and carrier-bars and the pins adjusted to give the desired angular relation of the sides of the teeth to the edge of the wheel. The inclination of the supporting-bar upon the attaching devices provides for the proper bevel of the teeth, and therefore upon rotating the wheel these will be ground thereby and correctly sharpened. After the operation upon the side of one tooth has been completed the sickle-bar is slid ,upon the carrier-frame, so that the next tooth may be sharpened. This may be continued until the teeth at the outer extremity are reached, at which time the frame as positioned will not properly support the sicklebar. The supporting-bar may now be shifted upon the attaching devices, so that their bolts occupy the openings at one end. This brings the wheel between an inner and an outer carrier-bar, which support the sickle-bar effectively until the last tooth is ground. This opera tion may then be performed upon the opposite end. One side of the sickle having been sharpened, the supporting-bar may be transferred to the opposite end of the wheel-frame and the other side ground in the same manner. It will be seen that the inclination of the supporting-bar not only provides for the correct bevel of the teeth, but also increases the space in which the crank may be operated,rendering it more convenient to turn.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A holder for sickle-bars comprising a supporting-bar, a frame mounted thereon having inner and outer carrier-bars extending forwardly from the supporting-bar, and retaining mem bers secured to the inner carrier-bars.

2. A holder for sickle-bars comprising a supporting-bar, a frame mounted thereon and having carrier-bars, retaining members secured to the carrier-bars, and means for fixing the position of the sickle-bar in diflerent portions of the retaining members.

3. Aholder for sickle-bars comprising a supporting-bar, a frame mounted thereon having inner and outer carrier-bars, retaining members secured to the inner carrier-bars, and means for fixing the position of the sickle-bar in different portions of the retaining members.

4. A holder for sickle-bars comprising a supporting-bar, a frame mounted thereon and having carrier-bars, retaining members secured to the carrier-bars and having openings, and pins situated in the openings.

5. Aholderforsickle-barscomprisingasupporting-bar, a frame hinged thereon having inner and outer carrier-bars extending for a considerable distance from the hinges, and retaining members secured to the inner carrierbars.

6. A holder for sickle-bars comprising a supporting-bar, a frame hinged thereon and having carrier-bars, retaining members secured to the carrier-bars, and means for fixing the position of the sickle-bar in different portions of the retaining members.

7. The combination With a grinding-Wheel, of a supporting-bar mounted in a verticallyinclined position thereon, and a carrier-frame hinged upon the supporting-bar.

8. The combination with a grinding-Wheel, of a supporting-bar mounted in a verticallyinclined position thereon, a carrier-frame hinged upon the supportingbar, attaching devices mounted upon opposite sides of the frame, one of said devices being higher than the other, and a carrier-frame supported upon said attaching devices.

9. The combination Witha frame, of a grinding-Wheel journaled thereon, driving means for the grinding-Wheel, attaching devices mounted upon opposite sides of the frame, those upon the driving side of the Wheel being higher than their companions, and a carrierframe supported upon said attaching devices.

10. The combination With a grinding-Wheel, of a supporting-bar mounted in a verticallyinclined position thereon, a carrier-frame hinged upon the supporting-bar, attaching devices mounted upon opposite sides of the frame, a carrier-frame coacting with the attaching devices, and means for fixing the carrier-frame upon the attaching devices in different positions transversely of the grinding- Wheel frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
