SICKLE-l-IOLDING ATTACHMENT FUR GRINDERS.

Application filed November 14, 1922, Serial No. 600,925.. Renewed February 9, 1925.

To all whom it may concern:

Be it known that LLARRY FURLONG, a citizen of the United States, residing at Havre, in the county of Hill and State of lliontana, have invented a new and useful Sickle-Holding Attachments for Grinders, of which the following is a specification.

This invention relates to an attachment for sickle grinders, one of the objects of the invention being to provide means for supporting a sickle during the sharpening operation. Sickle bars of mowing machines are very difficult for one person to handle during the sharpening operation because of their length and weight. The present invention includes ayieldablc means for gaging one end of a sickle bar to sup:;- said end and take care of the greater portion of the weight of the bar while the same is being fed to the grindstone.

Another object is to provide a structure of this character which can be connected readily to the supporting frame of a grindstone.

Another object is to prov de novel means for connecting the sickle bar to its supporting means.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can-be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a front elevation showing the attachment supporting a sickle or cutter bar in operative position relative to a grindstone.

Figure 2 is an enlarged side elevation of the bar engaging plate and adjacent parts.

Figure 3 is a plan view of the supporting plate shown in Figure 2.

Figure 4: is an end elevation of the structure shown in Figure 3, the bail being broken away.

Figure 5 is an elevation of the upper portion of the standard.

Referring to the figures by characters of reference 1 designates the supporting frame of an ordinary grindstone 2 such as used in the sharpening of cutter bars or sickle bars, this grindstone being operated by a foot pedal or in any other suitable manner. Suitably secured to the structure 1 is a bracket 3 having a terminal eye 4 in which is removably mounted a standard 5 the lowor end of which is adapted to rest on the ground or to extend thereinto. To the up per end of this standard is secured an arouate arm 6 adapted to overhang the grindstone. This arm can be used as a support for a sign board 7 on which suitable advertising matter can be placed. The sign board will also serve as a stiffening means for the arm. Outstanding from this arm are guide eyes 8 in which is slidably mounted a rope 9 or the like one end of which is connected to a rod 10. An eye 11 is provided between the ends of the rod 10 and is adapted to be placed in engagement with any one of a series of hooks 12 extending from the standard 5. Another eye 13 is provided at the end of the rod and constitutes a handle.

The free end of the arm 6 is folded or looped transversely to form a guide 14 through which the rope 9 extends and the free end of the rope is connected by a spring 15 to a bail 16 pivotally attached to the sides of a supporting plate 17. This plate has a recess 18 extending into one end thereof and upstanding from the plate near the recess are spaced lugs 19 to each of which is pivotally connected an angular button 20.

In using this device a sickle or cutter bar S is placed in inverted position so that that end containing a pivot eye E and a reenf0rcing rib will rest on the plate 17, the eye E proiecting into the recess 18 while the rib it projects between the lugs 19. Buttons 20 are then turned against the sides of the rib so as to grip it. Rope 9 is paid out or taken up so that the engaged end of the sickle or cutter bar S will be supported at the proper elevation. The person sharpening the sickle or cutter bar then grasps and supports the other end of said bar so as properly to feed the teeth to the rotating grindstone 2. As the greater portion of the weight of the sickle or cutter bar is supported by the attachment it will be obvious that said sickle can be easily manipulated during the sharpening operation.

lVhat is claimed is 1. An attachment of the class described including a standard, a bail yieldingly and adjustably connected to the standard, a supportin plate pivotally mounted in the bail, said pate constituting means for engaging and supporting one end of a sickle bar, and means on the plate for gripping a. sickle bar and holding it to the plate.

2. An attachment of the class described including a standard, a bail yieldingly and adjustably connected to the standard, a sup porting plate pivotally mounted in the bail, said plate constituting means for engaging and supporting one end of a sickle liar, upstandinglugs upon the plate for receiving a portion of the sickle bar therebetween, and clamping devices carried by said means for engaging and holding the bar to the plate, said plate having a recess for the reception of a portion of the sickle bar.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses,

LARRY FURLONG.
