CHARLES M. YOUNG, OF MILWAUKEE, WIS, ASSIGNOR OF ONE-HALF TO THE DENNETT HARVESTING MACHINE COMPANY, (LIMITED,) OF SAME PLACE- GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 322,770, dated July 21, 1885.

Application filed February 25, 1884. (No model.)

To all whom it may concern:

Be it known that I, CHARLES M. YOUNG, 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 to devices for operating the cord-holder in grain-binders; and it consists in peculiarities of construction, as will be fully described hereinafter.

In the drawings, Figure 1 is a vertical section through the grain-table of the binder, showing the needle in position after the twine has been cut. Fig. 2 is an outer side view of the knotter-frame; Fig. 3, an inner side view of the same. Fig. 4 shows the construction of the knotter-wheel cam-grooves, and Fig. 5 is a perspective View showing the tying mechanism in position when the knife is moving against the cord.

A is the binder-table, B the needle, (shown both in full and dotted lines,) 0 O are the grain-packers, and D is the breast-plate, all of which parts are exactly the same as in ordinary binders.

E is the knotter-frame, bolted, as usual, to the breast-plate D. It has the sleeve a in its upper end, and in this sleeve is j ournaled the outer end of the shaft b, carrying fast onto it the cam-wheel E, which is irregularly hollowed on its inner face to form an outer camgroove, 0, and an inner or central cam-groove, d. Opposite the irregular portion 0' of the cam-groove c is formed the segmental gearteeth 6, which serve to drive the tyer-shaft e.-

Fulcrumed on the bolt f, screwed in the outer face of the knotter-frame E, is the bellcrank lever F, whereby the cord-holding disk G is operated. The long arm f of this lever extends toward the cam-wheel E parallel with the outer face of the knotter-frame E, and a flange, f is formed on its end. This flange, which projects from the inner face of the lever, extends beyond the inner face of the knotter-frame, against which its end is bent. The inner edge of the flange f 2 is shaped so as to slide freely against the outer edge, e, of the knotter-frame, forming an arc of a circle, the center of which is the fulcrum-bolt f, and it is which one edge of the disk works.

extended downward opposite the cam-groove c of the cam-wheel E to form a bearing for the anti-friction roller f 3 working in said camgroove. As is obvious, the long arm of the crank-lever is squarely guided along the edge of the knotter-frame,and the pivoting-bolt f is freed from any twisting strain in the operation of the devices. The small arm f of the bell-crank lever F is perforated in its enlarged end to receive the threaded end of the adjustable carrier f the opposite end of which is bifurcated to form a hinge, f, for the pawl f.

A flange, f projecting from the upper edge of the carrier f, is provided on its-outer face with a stud, f", to support one end of the coiled spring f the other end of which is held over a like stud, f, formed on the corresponding notched end of the pawl f. f" is a nut, by means of which the pawl is given its proper adjustments. The carrier f is thereby adapted to move more or less, as desired, out of the perforated end of the lever F, and to be maintained at the proper point by the set-screw f, the end of which impinges in the groove f formed in the threaded end of said carrier.

G is the cord-holding disk, loosely mounted on the pin 9', held fast in the cross-bar g of the knotter-frame.

G is the shoe between the cheeks g of g This disk is made with the usual six notches, g, and on its rear face is formed the ratchet g, which is concentric with the disk G, and has the same number of teeth, their point lying opposite the center of the notch g and of a shape to take the free end of the pawl f His the knife-arm, which is pivoted on a stud, h, projecting on the inner face of the knotter-frame E and held thereon free to vibrate on its pivoting-bolt h. Its roundedupper end, h, is fitted,as usual,to work in the central cam-groove, d, of the cam-wheel E. Its lower part is provided on the inner face with a flange, h, the lower edge of which rests against the upper edge of a bracket, hi, that projects from the, knotter-frame and forms a curved guide-rail, the center of Which is the pivoting bolt h of the knife-arm. As the upper rounded head,h",of said knife-arm travels along the groove of the cam-groove (i the lower ratchet g end of the arm is thus firmly guided along the bracket. This not only relieves the pivotingbolt h from the twisting strain of the knife arm,'but also prevents any lateral displacement of the latter as it is moved back and forth by the cam-groove cl.

The operation of my device is as follows: The twine being laid by the needle 13 into one of the notches g of the holder G, the antifriction roller f of the bell-crank lever F engages in the irregular portion 0 of the cam groove 0. This will force the point of the pawl f against the ratchet 9 which it rotates till the notch in which the twine was laid has been received in the cheeks of the shoe G. The canrwheel E, making one revolution for every stroke of the needle, the movements of the parts are timed so that at each stroke the twine is laid in a new notch. Immediately after the cord has been drawn in the shoe G by the disk G the cogged segment 6 of the cam-wheel acts on the knotter-pinion and shaft 6, and the knot is formed in the usual manner. As soon as this is done the antifriction roller f is ready to leave the irregular portion 0 of its cam-groove c, and as it does causes the pawl f to recede back in position to engage with the next tooth of the In this position the point of the pawl keeps the cord-holder fast in the shoe, as when the knot was being tied, so that when the rounded head 71/ of the knife-arm H meets with the irregular portion d of the central cam-groove, (Z, to move the knife h against the cord this latter can in no possible way be detached from the holder.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the knotter-frame E, the bell-crank lever F, the carrier f supported in the outer arm, f", of said lever, and having a threaded end and a groove, f, a setscrew, f engaging said groove, the adjusting-nut f, and the spring-pawl f pivoted in the bifurcated end of the carrier f", substantially as and for the purpose set forth.

2. In a grain-binder, the combination of the cam-wheel E, provided with the cam-groove c, the knotter-frame E, having the curved flange e", and the bell-crank lever F, pivoted to said frame and provided with a hooked flange engaging the curved flange on the frame. and with a roller,-f, engaging in said groove 0, substantially as and for the purpose set forth.

3. In a grain-binder, the knotter-frame E, having a curved flange, h in combination with the cord-guiding arm G, pivoted to said frame and provided with a flange, h adapted to bear against and slide upon said curved flange, substantially as and for the purpose set forth.

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

CHARLES M. YOUNG.
