CUTTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 304,686, dated September 9, 1884. Application sied November 2o, 1893. (Nomade.)

T0 all whom t may concern:

Be it known that I, HORACE R. ALLEN, of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Cutting Appa-` ratus for Harvesters; and I do hereby declare that the following is a full, clear, and exact description ofthe same.

My invention relates to improvements in the cutting apparatus of harvesters, the object being to overcome the ordinary sliding fric tion between the fiugerbar, the guard-ngcrs, and the cutter-bar; and it consists in providing anti-friction devices for all the bearingpoints of the cutter-bar, also, means to prevent the clogging of the sickle, and convenient 'means for lubricating the anti-friction rollers.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical section taken lengthwise of one of the guard-fingers. Fig. 2 is a plan view of one of the guard-fingers and ledger-plates, showing the rear and lower rollers, the cutter and finger bar being removed. Fig. 3 is a plan of a portion of the finger-bar, showing the top of the lubricator., and also the sickles and one of the fingers.

Throughout the drawings, A represents the finger-bar; B, the guard-fingers; G, the cutterbar; G', the knives, and K the ledger-plates. The finger-bar A is rolled from a plate of iron or steel into the shape shown in cross-section in Fig. l, forming a base'plate, A', an overhanging top plate, A2, and an inclined connecting-plate, A. The ingers B are secured to the bar A by bolts H, which pass through the overhanging portion A2 of such bar. In eachv finger is formed a circular recess, B', Figs. 1 and 2, in which is journaled a roller, C, the bolt H forming the pivot upon which the roller turns. The roller projects forward slightly beyond the shoulders m, Fig. 2, so as to bear against the cutter-bar and sickle when they are in position, as shown in Fig. 3. The cutter-bar is of ordinary construction and operates in the usual manner in connection with the ledger-plates K.

Instead of the ordinary sliding contact between the sicklebar and the ngers, I form a square recess in each finger, Fig. 2, directly under the cutter-bar G. Hthin the space thus formed are journaled-rollers E, upon which the cutter-bar rests and reciprocates. Each roller E is j ournaled on a pin, e, which is held at the rear end by a recess in the ringer, and at the other by an opening in a flange of the ledger-plate,turned down over the edge of the recess in which the roller is placed. The pin e,besides forming a support for the roller, also holds the ledger-plate in position, dispensing with the screw-fastening commonly employed.

In order to automatically lubricate the bearings of the anti-friction rollers, I have mounted upon the finger-bar oil cups or reservoirs F, Fig. I. Each reservoir is made of.

sheet metal, with a bottom shaped to iit the upper surface of the finger-bar, to which it is secured by the bolt II,before described.' The reservoir is lled through a hole in the top, closed by a screw-plug,f, and has an outletorifice, J, extending along the bolt H, and leading the oil to the bearing of the roller C. A wick, I, is preferably placed in the reservoir to absorb the oil,prevent its too rapid escape, and conduct it from the lower portion of the reservoir to the point of discharge. In the front part of the oil-cup is a recess, in which is journaled' upon a'pin, d, aroller, D, which bears upon the upper surface of the sickle and aids to hold it in place.

In the cutting apparatus ordinarily used there is a tendency,in operating,to crowd the sickle-bar back against the finger-bar, and also to give it an upward thrust. The effect of this, where there are plane surfaces land sliding friction, is to cause the sickle-bar to bend and clog. My method of interposing bearing-roll; ers between the plane surfaces ordinarily in contact reduces the friction and tends to prevent clogging. This latter result is also attained by causing the iinger-bar to project forward over the sickle-bar, as shown in Fig. l.

I may use a separate set of rollers and an oil-cup for each ringer, or one for every other finger, or may place them at different distances apart, anduse any number that will accomplish the best results..

Having described my invention, I claiml. The combination, With the ringer-bar, the guard-ingers, and the cutter-bar, of a series IOO of horizontal rollers pivoted between the finger-bar and the ngers, and pivot-bolts H, passing through said finger-bar and fingers, substantially as described.

2. In a reaper or mower, the combination of the ringer-bar, the guardiingers, the rollers C, the bolts H, and the oil-cups,substantially as described.

3. The combination, with the guard-fingers and rollers C E, journaled in separate recesses therein, of the sliding cutter-bar and a bearing-roller, D, journaled above the said cutterbar independently of the guard-fingers, all substantially as described.

4. In a reaper or mower, the combination ofthe recessed guard-fingers, the sickle-bar,

and the rollers E, iournaled in said recesses, substantially as described.

5. The combination of the recessed guardfingers, the sickle-bar, the rollers E, and the 2o fianged ledger-plates,substantially as set forth.

6. The combination ofmthe supported oilcups, the rollers D, and the sickle-bar, substantially as set forth.

7. The combination, with the nger-bar 25 having the elevated overhanging flange A2, of the fingers having circular recesses, the rollers C, and the sickle-bar.
