KNOTTER FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 394,536, dated December 11, 1888.

Application filed March 15 1888.

To all whom it may concern:

Be it known that I, IVILLIAM F. GOAD, of Mount Pleasant, in the county of Maury and State of Tennessee, have invented certain new and useful Improvements in Knotters for Harvesters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a side elevation of my improved twine-knotter for grain-binders, partly in section. Fig. 2 is a front elevation of the same, partly in section. Fig. is a detail enlarged rear elevation of the same, partly in section.

4 is a sectional detail view of the cordholding devices.

This invention relates to improvements in cord-knotters for grain-binders; and it has for its objects to provide improved cord-holding devices, cord-knotting bill, and, cord-severing mechanism; and to these ends it consists in the novel construction and arrangement of parts, and of the supporting-frame for these parts,as will be clearly understood from the within description, in connection with the drawings, and particularly specified in the claims hereto appended.

I11 the drawings, the letter A represents the frame of the knotter, which is provided with an upper sleeve, a, in which is journaled the gear or driving shaft A. Below sleeve a is the needle-opening a, and at one side of said opening at right angles to sleeve (6 and below the same is enlarged portion A of the frame, in which are formed bearings for the knotterbill shaft and for the twine-holder shaft, as hereinafter referred to.

B designates the cam and gear disk which operates the knotting devices, and which is mounted on shaft A. Near the outer periphery of this disk is formed on its face the radial teeth Beight in numberwhich are adapted to engage at proper time the pinion on the shaft of the knotter-bill and rotate the latter. The knotter-bill is mounted on the lower end of a short shaft, 0, journaled in bearings formed in part A of the frame, as shown, and the pinion c on shaft 0 rotates in .an opening, a, in part A", as shown, so that Serial No. 267,210. (No model.)

while it can engage teeth tected from injury.

C is theknotter-bill, the lower jaw of which is curved laterally in a hook shape, as shown in Fig. i, and is provided with a slot, C, at one side of which is formed a vertical shoulder, C, which is to prevent the cord passing too far between the jaws of the bill, and this lower jaw is also formed with the throw-off cam on its side opposite to and above the hooked end of the jaw and standing above shoulder as shown. The upper jaw, C, of bill (J is curved similarly to the lower jaw, and is pivoted in a vertical slot, 1*", and projects rearward, as shown, so that its rear end will engage a canrspring, D, on the lower end of a vertically-adjustably shaft, (1, which has proper bearings in part A of the main frame to one side of and parallel with shaft 0, and is held by a set-screw D, as shown. This cam causes the jaw C" to bite the cord firmly at the proper time to make a tight knot.

If desired, a roller, D may be mounted 011 the rear end of bill C for engaging cam D. Cam I) can be adjusted to regulate the tension or bite of the bill on the cord, and adapt the same for different diameters of cord.

E represents the cord-holder plate or disk having a series of deep notches, E, in its periphery, and mounted on an inclined spindle, E, removably secured in proper bearings in part A" of the main frame, which is properly recessed, as shown, to receive the disk and shaft.

6 represents a pinion on spindle E, the teeth of which are formed diagonally, as shown, and correspond in number with the notches E.

6 represents a delay-shoe on spindle E above pinion e, which is provided with a number of squared faces corresponding with the teeth of the pinion. The spindle E is secured in position by a set-screw, 6 The disk E, pinion e, and delay-shoe 6' may be cast in one piece, or rigidly united, so as to operate together. edge, e, at the periphery of disk B, as shown, and pinion e is rotated one tooth by means of tooth F, formed on an oifset portion, f, of disk B at the periphery thereof, which is inclined to the axis of the disk, as shown, to properly it will be pro- Delay-shoe e is held by a delay:

engage the diagonal teeth of pinion 6. At the base of tooth F is formed the notches F in the delay-edge 6, so that when pinion e is rotated the shoe e can also rotate to bring a new face against the delay-edge of the disk B.

G indicates a slotted shoe partly embracing the periphery of disk E and mounted on or formed integral with a sprin g-supporting arm, G, adjustably secured to a convenient portion of the main frame by a bolt or set-screw, fr", passing through a slot in arm G, as shown.' By adjusting this arm the shoe can be arranged in such relation to the notched holderdisk as to catch and hold with the requisite tension either large or small twine.

g is a spring-arm attached to the outer lower side of shoe G and bearing against a side piece of the frame, as shown. \Vhen the cord is engaged between shoe G and disk E, arm Q will bind against the side of the frame and prevent the shoe being drawn inward toward the knotter or binding against the outer side of disk E.

H indicates the cutter-arm, which is U- shaped and pivoted by one of its legs upon a stud, h, on frame A below sleeve a. The upper end of arm H extends forward to the disk B and carries an anti-friction roller, I-l, playing in a groove, h, insaid disk. This groove h is formed at one portion into a short cam, h, which is arranged in such relation to the teeth that operate the kn otter-bill shaft as to actuate arm H at the proper moment, which is when the knotter-bill has completed the knot. The arm II is curved, so as to be out of the way of the needle-bar at all times, and.

to its lower end is attached a removable knife, I, as shown, which is provided with a widened rounded head, that when the knife is in a normal' position lies just underneath the twine that is brought up by the needle and engaged with disk e, so that when the needle is re tracted, should the twine drop, it will impinge upon the upper edge of knifeI and be sup ported thereon in position for engagement by the knotter-bill, thereby insuring the tying of the knots and binding of the bundles at all times.

The arm H is controlled by a spring, J, secured to frame A and bearing upon said arm, as shown, to keep it from vibrating at all times, except when actuated by cam 71', as it would otherwise do, since roller H is necessarily of less diameter than the width of grooves h.

The bottom of frame A is covered with a thin plate of metal, K, provided with a needle and cord slot, is, so that the working parts will be kept from contact with the straw or hay being tied.

The number of teeth on the offset of disk U E may be increased, so that in place of one ,a shaft for the cord-holding disk is a great advantage, since when it becomes worn it can be readily removed and a new spindle substituted, and there will be no wear of the journals of the cord-holding devices in the part A The knotter stands at an angle on the machine, and the crooked bill turns up in position to catch and hold the twine until it makes the knot.

As there is nothing between the bundle and knotter-bill but the thin steel plate, and as the billvworks very close to the latter, the bundle is tightly tied, and no expansion of the bundle is required to tighten the band.

The pinion c has a shoulder or delay-recess, 1), formed in its upper edge,which engages the delay-edge b on the disk B after the pinion c has been once rotated, and thus the pinion and knotter-bill, after each rotation by the teeth B, are held in position until the teeth B again engage the pinion c.

Having described my invention, I claim- 1. In a knotter, the combination of the knotter-bill 0, having pivoted jaw G, with the adjustable cam D, engaging said jaw, all constructed and arranged to operate substantially in the manner and for the purpose specified.

h, and cam h for actuating arm H, a series of teeth, B, for actuating the knotter-bill, a delay-edge, e, for shoe e, and an oifset tooth, F, for engaging pinion e, all-substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
