GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 339.523, dated April 6, 1886.

Application filed August 12, 1884. Serial No. 140,364. (No model.)

T0 at whom it may concern: 7

Be it known that I, JOSEPH P. BULLOCK, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Grain- Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates tograin-binders; and it consists in certain new and useful improvements in the tying mechanism thereof, as will be fully described hereinafter.

In the drawings, Figure 1 is a perspective view of the tying mechanism of a grain-binder embodying my invention. Fig. 2 is an elevation of the same. Fig. 3 is a plan of my improved knife-bar. Fig. 4;:IS an end view of the tyer-wheel and the parts as seen when looking in the direction of the tyer-wheel. Fig. 5 is a vertical section of the tying mechanism, taken through the center of the cordholder. Fig. 6 is an elevation of that end of the knotting or tying mechanism opposite that shown in Fig. 4.. Fig. 7 is aplan ofthe breastplate. Figs. 8, 9, and 10 are plan views of my improved knotter, showing the position of the parts at various stages of its operation. Fig. 11 is a central vertical section on line a: at, Fig. 8; and Fig. 12 is an edge view of the tyor-wheel.

A is the knotter-operating wheel, which is mounted, as usual, on the kuotter-operating shaft A. Ihis wheel A has on its outer run a cam-flange, B, which may carry its dischargearm, and this flange B has flared ends or extremities b 5, while its central portion is straight.

C is the knife-bar, which has secured to 1t near its center the knife 0, and is also cutout to form a finger, (I. This knife-bar fits in ways in the breast-plate a, and has on one end a stud, C", that carries a roller, 0, ior contact with the flange B. I

G is a spring, one end of which Is secured to the breast-plate, while the other rests against the inner side of the roller 0 and serves to retract the knife-bar after it has been advanced and as it is released by the flange B.

Above the knife-bar I secure an inclined and tapering cord-guide, d, to the breastplate. This guide projects over the needleopening in the breast-plate to receive the cord as the eye of the needle enters the knotter.

The operation of my device is as follows:

Just after the cord has been carried about the gavel, that portion of it between the knotter and the gavel lies across the guide d, as in Fig. 8, and the parts are so timed that at this moment the knotter begins to turn and engages with the cord, as in Fig. 9, drawing it off of the guide (2', from whence it falls to the finger d, which latter supports it and prevents it from falling down out of engagement with the bill while the loop is being made; and about this time the flange B begins to advance the knife-bar, which completes its travel, cuts the gavel-cord, and carries the finger d from under the cord and permits the gavel to draw the knot down off of the bill as soon as the knotter has done its work. In other words, the cord is first held by guide (1 in position to be taken by the bill as it be gins to turn, and then after the bill has taken the cord, the latter is guided down onto the finger d and toward the shaft of the bill, the finger at preventing it from falling away from the bill until the loop is made, and then as the cord is cut the finger will. be drawn from beneath it, so as to permit the bundle to drop to the rear and draw the knot off of the bill.

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

1. The flanged knotter-operating wheel, in combination with the knife-bar having finger d, and a guide attached to the breast-plate and projecting partly across the needleopening.

2. The combination of the tyer-wheel, its flared flange B, and the knife-bar having finger d, with the cord-guide d, as set forth.

3. The combination, with a knife-bar adapted to reciprocate across the breast-plate and having a finger for supporting the cord until the loop is made, of a guide adapted to support the cord in position to be taken by the bill and to guide the cord toward the shaft of the bill and down upon the finger.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of \Visoonsin, in the presence of two witnesses.

JOSEPH P. BULLOCK.
