HARVESTER CUTTER-BAR.

SEECIFICATION forming part of Letters Patent No. 453,705, dated J une 9, 1891.

Application ledDecember 15, 1890. Serial No. 374,777. (No model.)

T0 if/ZZ whom, t 71mg/ concern.-

Be it known that I, JERRY L. RIELEY, a citizen of the United States of America, residing at Troutville, in the county of Botetourt and State of Virginia, have invented certain new and useful Improvements in Harvester Cutter-Bars, of which the followingI is a specilication, reference being had therein to the accompanyin g drawings.

This invention relates to an improvement in harvester cutter-bars of that class in which the knives are held in place by means of a longitudinally-movable locking-bar having lugs or projections engaging recesses in the knives, and has for its objects, first, to provide means for reciprocating the locking-bar, so as to lock or release all the knives at one operation; secondly, to providea knife-bar having means for holding the knives securely in place against vertical and lateral .play 1ndependently of the locking-bar; thirdly, to provide means for preventing any vertical or lateral play of the locking-bar, and, finally, to provide a cheap, eiiicient, and durable cutterbar.

The invention will rst be described in connection with the accompanying drawings, and then pointed out in the claims.

In the drawings, Figure l is a perspective view of the complete cutter-bar, showing the parts in locked engagement. Fig. 2 is a side elevation of the same. Fig. 3 is a top plan View of the cutter-bar, the locking-bar being removed. Fig. et is a side elevation of the cutter-bar. Fig. 5 is a similar View ot'- the locking-bar. Fig. 6 is a transverse sectional view taken on the line @c of Fig. Fig. 7 is a similar view taken on the line y J of Fig. 5. Fig. 8 is a plan view of one of the knives, and Fig. 9 is an edge view of the same.

Referring to the drawings, A designates the cutter-bar, one end of which is bent upon itself to form an arm l, between which and the said bar is secured the guide-plate B. The arm is provided with a standard f2, having a threaded opening near its upper end designed to be engaged by the enlarged portion of a diiterentially-threaded bolt 3, the reduced portion of which engages a superimposed locking-bar C, whereby to .cause the .said bar to reciprocate as the bolt 1s rotated'in opposite directions, for a purpose that will be described farther on. The upper surface of the cutter-bar is provided with a series of transverse bosses 4i, the side edges of which are underbeveled, as shown at 5, thus forming a series of transverse dovetail recesses 6, in which fit the shanks 7 of the knives I). The sides S of the Shanks and also the shoulders 9 of the knives are beveled, the beveled portion of the Shanks engaging the underbeveled portions of the bosses and the beveled shoulders of the knives engaging the underbeveled front edges 10 of the bosses. By thus beveling the slianks of the knives and providing dovetail recesses in the cutter-bar, in which they it, a rigid adjustment of the knives against lateral play is secured, and by means of the underbeveled front edges of the bosses all danger'cf vertical play of the knives will be overcome.

The locking-bar C is provided at one end with a standard 1l, which is engaged by the reduced threaded end 12 of the bolt 3, and the under side of the said bar is provided with a series of dovetail locking-lugs 13, designed to engage similarly-shaped recesses 14:, formed in the side edges of the bosses 4;, and also with dovetail recesses 15, formed in one side of the shanks, whereby the knives are not only locked in place, but the locking-bar is prevented from having any vertical play, inasmuch as one portion of each of the lugs 13 is in engagement with the recesses 14 and the other portion with the recesses 15,

In securing the knives in place on the cutter-bar the bolt 3 is turned so as to draw the lugs 13 back into the recesses 14 to allow the shanks of the knives to be inserted within the recesses 6, which shanks are of a width to fit snugly therein. The bolt is then turned in the opposite direction, thus projecting the locking-bar forward and bringing the lugs into engagement with the recesses 15, thus locking the knives in place. By reason of the differentially-threaded bolt the lockingbar can be reciprocated with ease either to lock the rknives in place or to permit of the removal of one or more of them when desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a cutter-bar pro- IOO vided on its upper side with recessed bosses, and recessed knives fitting between said bosses, of a superimposed locking-bar having lugs upon its under side adapted to engage the recesses in the bosses and in the knives.

2. The combination, with a cutter-bar provided on its upper sidewith recessed bosses, and recessed knives ittin g between said bosses, of a superimposed longitudinallymovable locking-bar having lugs upon its under side adapted to be received wholly within the bosses, and means for moving the locking-bar so that its lugs will at the same time be in engagement with the recesses in the bosses and in the knives.

3. The combination, with a cutter-bar provided on its upperside with recessed bosses, and. recessed knives fitting between said bosses, of a superimposed longitudinallymovalole locking-bar having lugs upon its under side adapted to engage the recesses in the bosses and in the knives, and a differentiallythreaded bolt connecting the cutter-bar and the locking-bar.

4. The combination, with the cutter bar having a series of transverse recesses and 1ongitudinal recesses connecting therewith, of a series of knives inserted in the transverse recesses and recessed to register with the longitudinal recesses, a superimposed lockingbar having lugs engaging the longitudinal recesses, and means for projecting the lockingbar to bring the said lugs also into engagement with the recesses in the knives.

5. The combination, with a cutter-bar carrying transverse bosses having underbeveled side and front edges, of knives having beveled Shanks engaging the side edges, and beveled shoulders engaging the front edges of the said bosses, and a superimposed lockingbar interlocking with the knives and with the cutter-bar.

In testimony whereof I affix my signature in presence of two witnesses.
