HARVESTER-CUTTER.

EPBCIEICATION forming part of Letters Patent No. 351,004, dated October 19,1886.

Application filed January 6, 1&6. Serial No. 187,808.

To all whom it may concern.-

Be it known that I, LEONARD STUDY, acitizen of the United States, residing at McIaul, in the county of Fremont and State of Iowa, have invented certain new and useful Improvements in Harvester-Cutters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to cutting apparatus for reaper and mowing machines; and it consists in combining therewith an attachment to prevent the rear edge of the cutter-bar and the front edge of the fingenbar from rubbing together, thereby reducing the friction and the wear of the parts, by which a lighter draft is secured.

The object'of the invention is to secure a parallel motion of the cutter-bar during its reciprocating movement and prevent the rear edge engaging with the finger-bar.

To these ends it consists in the novel features hereinafter more fully set forth and claimed.

In the drawings, Figure l is a plan View of a cutting apparatus provided with my attachment, parts being broken away to show its construction. Fig. 2 is an inverted plan view of the case with the operating parts in position. Fig. 3 is a perspective detail of a portion of the cutting apparatus and one end of the case, showing the means for fastening it in place; and Fig. 4 is a similar View showing the opposite side of the case and the means by which it is held in place.

The fingers a, fingcnbar A, and cutter-bar B are of ordinary construction and operation.

A case, 0, secured to the finger-bar, projects over the cutter-bar and holds the latter in 0 fits in between the posts e and e, and the catch or lever E is pivoted at one end to the (No model.)

points of attachment between it and the rods F shall be at a distanceapart, as shown at g. The free end of thelink is pivotally connected with the cutter-bar g.

The rods or bars F and G are so disposed that the free end 7 of the link moves in a straight linc,.always remaining parallel to a line passed transversely through the normal position of said end or point 9. In practice the end 9 is bent at'right angles to the link and enters an opening, I), in the cutter-bar. It is evident that as many of these attachments may be provided as is necessary, and that they may be located at any point or points found most convenient.

It must be observed that the length of the rods or bars F is equal to the distance between the points 9 and y,-. also that the rods incline or gradually approach each other from the points f to their pivotal connections with the link. The points fare fixed relative to the finger-bar and the point 9 fixed relative to the cutter-bar. In the operation of the latter the bars F are vibrated about the points f, and the distances between thepointsf and the point g vary proportionally to the inclination of the rods in such a manner as to cause the point y to move in a straight line, which at all times will be parallel to a line drawn through or between the points f f.

While the case is shown attached to the finger-bar, it is evident that the parts may be reversed without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. The combination, with a finger-bar and cutter-bar, of a pair of rods or bars pivoted on the finger-bar,and a link. pivotally connecting the two and pivoted to the cutter-bar, whereby the cutter-bar is steadied in its longitudinal movement and the abrasion between its rear 8. The combination, with the finger and cutter bars, the pair of rods and a link pivotally connected at one end with the adjacent ends of the rods, of a case inclosing the rods and link, provided with lugs c and the lug c, the 20 casting D, having lugs to engage lugs c, and a catch to contact with lug 0', whereby the bars; link, and cutter-bar are removahly held in place, substantially as set forth.

In testimony whereofI affix my signature in 25 presence of two witnesses. LEONARD STUDY;
