CORD-KNOTTER FOR HARVESTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 525,463, dated September 4, 1894.

Application filed April 25, 1892. Serial No. 430.616. (No model.)

To all whom it may concern:

Be it known that I, Moses 'A. KELLER, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Cord-Knotters for Harvesting-Machines, of which the followingis a specification.

My invention relates to improvements in which a rotary cord holder is journaled about a rotary knotter, and it relates further to various other improvements in combination with said cord holder and knotter, all of which I attain by the mechanism illustrated in'the accompanying drawings, in which Figure 1, is a right hand side view with all its operating parts in their normal position. Fig. 2, is a bottom plan of Fig. 1. Fig. 3, is a sectional view taken through the line B. B. of Fig. 1, showing the top of the cord guide and thebreast-plate, and a portion of 'the cord holder in its normal position. Fig. 4 is a vertical sectional view taken through the lines D, D, of Fig. '7 and line Y, Y, of Fig. 2. Fig. 5, is a left hand side view, and Fig. 6, is a bottom plan of Fig. 5, with the working parts all in their normal position. Fig. 7, is a front side view, and Fig. 8, a rear side view. Fig. 9.is a rear side view of the knotter, separated from the frame. Figs. 10. and 11. are sectional detailviews. Fig. 12 is a bottom plan of Fig. 7, but with cord andpoint of binding needle in position just at the point where the looping jaws begin to start, and Fig. 13, is a bottom plan of Fig. 8, which is identical with Fig. 12, but shows the position of the cord on the looping jaws as the same appears at the point where the ends of the cord forming the band are drawn between the jaws and just at the point where the jaws begin to close on the cord. Fig. 14. is a right hand side View with a portion of the cord guide removed to show the position of the cord just at the time the looping operation begins. Fig. 15. is a vertical sectional view taken through the line A. A. of Fig. 1, with the looping jaws removed from the knotter spindle to better show the construction and position of the cam that controls the pivoted looping jaw. Figs. 16. and 17. are sectional views of the looping and cord holding mechanism taken through the line F. F. of Fig. 14, and

Fig. 18 is a bottom plan of the combined cam plate and cord guide, and which forms the housing for the cord holder cup, and clamping shoe, and as-the same appears when detached from the knotter frame and other parts, and Fig. 19 is a view of the reverse.

side of same plate as Fig. 18.

Similarletters refer to similar parts throughout the several views.

The main frameA. is bolted by the bolt j, to the breast plate I, as shown in Fig. 4. Journaled in its upper end is the main operating shaft B, to which is affixed the knotter operating wheel 0, and thereby is caused to rotate with the shaft, and gives motion to all the knotting mechanisms as will be shown hereinafter. The sleeve G. of the cord holder, and the knotter spindle F. are journaled in the main frame, transversely to the shaft B,

but the spindle F, is journaled in the sleeve G, so that its motion is independent of the sleeve. A pinion K, is rigidly secured upon the spindle F, near its upper end as shown in Fig. 4. This pinion .has just enough cogs to correspond with the. cogs c on the face of the wheel 0, to cause it to make one complete revolution to one revolution of the wheel 0, no more no less, and is locked in its normal position by the flange b, that is on the face of the wheel 0, which bears against a delay surface n, formed on the pinion see Fig. 5, and 15. The pinion M. is secured. to the sleeve G. at the upper end as seen in Fig. 4, and at the. lower end of the sleeve is formed the crown shaped cord holder D. A supplemental double pinion L, is journaled upon the spindle N, at the rear of the frame, and its upper portion has just as many cogs as pinion K, and is engaged and rotated by the same segment cogs c, of the wheel 0, and therefore makes but one complete revolution, to one revolution of wheel 0, and is locked in its normal position in the same way as is the pinthis construction it will be seen that the pin- I IOO direction to the rotation of the knotter. The

object of this construction is, to do away with the usual knot stripper arm by having the looping jaws stand in the direction of the dis- 5 charge of the bundle, while in their normal position as seen in Figs. 1, and 2, so that the loop is pulled oft the jaws as the bound bundle is discharged, but while the jaws of the knotter must stand in th s position to allow the loop to pull off, it was with no little diffieulty to get the ends of the cord forming the band between the opened jaws in time and draw them in farenough, before the jaws must close,but this difficulty is entirely overcome by the cord holder journaled concentric with the knotter spindle, and rotating in the opposite direction to the knotter, and thereby positively draw the cord between the jaws as will be fully pointed out farther on.

The combined cam plate, which is shown by the drawings Figs. 18 and 19 forms the cams E U and the cord guide H, and cord finger H, and these parts thus become all integral. This plate also forms a housing on the rear side of the cord holder cup, into which are arranged the cord clamping shoe J and its spring P, as seen in Figs. 16 and 17, the

lugs

4 and 5, form means by which the plate is bolted unto the frame A, by the bolts t and r, the cam part U, fits down into the cord holder cup D, as seen in the sectional view Fig. 15, and. is provided with a hole concentric or in line with the hole in the sleeve of the cord holder cup, through which passes the knotter spindle, and when the knotter is in its place and rotated the little roller on the pivoted knotter jaw, alternately comes in collision with the cams U and E, and thereby the looping jaws are opened and closed at the proper time.

In order that the rift S, in the breast-plate may be unobstructed by a cord rest, I have formed a cord rest it, on the base of the looping jaw f, as shown in Fig. 14, and several others, and have provided a cord guide H, to guide the cord unto the finger or rest, the peculiar construction and shape of the rest h, allows the cord to slip off, and drop onto the looping jaws f and g, as soon as the same are in a position or at right angle to the cord, see Fig. 11, thus doing away with the stationary rest over the rift in the breast-plate, and making absolutely sure of the cord being secured by the looping jaws. The cam plate forms a circular recess at its lower edge, on which the cord holder cup bears, see Fig. 4, and also forlnsa recess for the cord clamp J. and spring P, see Figs. 16 and 17, and a tension screw W. is threaded in said plate to regulate the proper amount of tension to hold the cord against the cup D. A flange V. is formed at the base of the cup to prevent the cord from getting up in the bearing, and to form a guide for the clamp J. The crown shaped cup D. 6 is provided with two (2) cord holding notches d, to securethe cord and carry it around unof the flange and thereby forming in conjunc- 15 tion with the notched flange a shear cutteraa the cord holder cup rotates and carries the cord against the knife in the manner hereinafter more fully described. There isa notch q formed in the breast-plate I, the walls of which prevent the cord from slipping oi the looping jaws until the latter are come to their normal position.

The operation of the mechanism as a wholo while tying a knot, is as follows: The normal position of the knotter, with one end of till binding cord, is shown in Figs. 1, and 101. When the needle, 0, has placed the cold around the grain or gavel the other end of the cord forming the band is also brought in the same position on the cord rest h, as shown in Figs. 14, and 12. While the needle was thus in motion the knotter operating wheel C, has also been set in motion and is now in theposition shown in Fig. 14. The cogs 0, will ne 95 fall in gear with the knotter operating pin- 1 ion K, and set in motion the looping jaws f and g, and as soon as the cord rest h, hll moved past the cord guide H, the cord drop. unto the looping jaws, as shown in Fig. 11, but there will be two strands of the cord instead of but one as seen in said figure, and when the looping jaws have thus secured the cord, the cogs, c, of wheel 0, now fall in gas! with the pinion L, and start thereby the cord holder cup D, which turns in the opposite direction to the looping jaws. See arrow point! Fig. 17. The end of the cord held by the holder is not carried around with the holder cup but as the holder rotates it pays out the cord to the knotter, while the other strand of the cord is caught by the notch d, and carried around and clamped between the periphery of the cup D, and clamp J, as seen in Fig. 17, and 16. In Fig. 16, the looping jaws an in position and separated to allow the 00d holder to draw the ends of the cord between the jaws and when the latter have reached the point shown in Fig. 13, the loop is completed and the jaw g, is closed upon the end. of the cord by the rollerscoming in collisiol with the cam E, as seen in Fig. 13, and as soon as said jawsare closed, the holder cup carries the cord against the knife R,see Fig. 13, and thus severs the cord while the old and is released,and as the cogs c, passout of goat with the pinion L, the holder cup has reached its normal position and the loop of the applied band pulls 01f the jaws and completes the knot as the bound bundle is'carried out by the ejecting mechanism. In the mean time the binding needle has also returned to its r i mt normal position and again placed the cord on the cord rest it, as seen in Figs. 1, and 10, and the cord is now in position to receive the grain for the next bundle.

The ends of the cord at a, in Figs. 12, 13, and 14 represent the bandthat would be around the bundle while the knotter is in operation tying the knot.
