GEORGE G. HUNT, OF BRISTOL STATION, ASSIGNOR OF ONE-HALF TO THE PLANO MANUFACTURING COMPANY, OF PLANO, ILLINOIS.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 339.989, dated April 13. 1886.

Application filed November 30, 1883. Serial No. 113,235. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE G. HUNT, a citizen of the United States, and residing at Bristol Station, in the county of Kendall and State of Illinois, have invented a certain new and useful Improvement in Grain-Binders, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- 1o Figure l represents an outer side view of a knotter-frame and attachments embodying my invention; Fig. 2, a cross-section of the same, taken on the line a: x, Fig. l, but reversed in position; Fig. 3, a section of the same, taken on the line y y, Fig. 2; Fig. 4, a detail plan of the plunger-bolt and its connections with the cutter.

My present invention relates to that class of grain-binders in which an automatic tripping 2o mechanism is employed for sizing the bundles,

and cord is used as the binding material.

' The improvements relate to the mechanism for holding and cutting the cord.

I will proceed to describe in detail such parts of a grainbinding machineas are necessary to a full and complete understanding of the construction and operation of my invention as I have embodied it in practical form in a working machine, and will then point out definitely in the claims the special improvements which I believe to be new and wish to protect by Letters Patent.

In the drawings, A represents the knetterframe or small frame on which the cord holding and tying devices are mounted, and B the main shaft or" the binder. On this shaft is 'mounted the main cam-wheel O, which is provided with gearsectiou c, as usual, for imparting the required motion to the knotting-hook,

40 which is provided, as usual, with a pinion, d, and is mounted in suitable bearings on the knotter-frame. The cord-holder E is a notched disk, and at one edge runs in a grooved clamp or keeper, F, which in this instance is pivoted,

and has an actuatingspring, f, arranged behind it. All these parts are of ordinary general construction, and will be sufficiently well understood without a more particular description in the present instance.

I employ a plunger-bolt, G, to operate th cord-holder; but I make this device of peculiar construction and connect it with the cutter,

so that it serves also to operate the mechanism for severing the cord, and I also provide for driving the plunger-bolt positively in each direction of its reciprocating motion. The lastmentioned result I obtain by mounting the plunger-bolt in the arms a of the knotterframe, which depend from the main shaft, andl in such manner as to leave it free to slide back and forth in its bearings. A small cam-wheel,

H, is mounted on the main shaft outside of the binder-head, and on the opposite side of the latter to that on which the wheel C is located. lhe plungerbolt extends from one of 65 these wheels to the other, aud the wheel C is provided with a ring-cam, c', on its inner face, arranged to bear against the end of the plunger-bolt at that side of the knotter-i'rame being cut away partly atcz, as shown in Fig. 2 of 70 the drawings. The wheel H is also provided with a short cam, h, on itsinner face,arranged to act upon the opposite end of the plungerbolt, and also located so as to correspond substantially with the break or cut-out in the cam 7 5 c. Obviously, during the revolution of the main shaft the cam c will for the greater portion of the time act on the plunger-bo1t,and will hold it at the end of its movement toward the small cam-wheel H, its opposite end be- 8o ing in contact with the face of the latter wheel,

as shown in Fig. 3 of the drawings. This is an inoperative position of the plunger-bolt,

or its position when all the parts actuated by it remain in a state of rest. Vhen, however, in the revolution of the main shaft the cam h is brought into contact with the plunger-bolt, the latter will be reciprocated in the opposite direction, the cut-out in the cam c' permitting this movement, and this motion of the go plunger-bolt operates the cord-holder and the cutter, as I will now describe, t-he parts of course being arranged and timed to produce these operations at the proper moment. The ends ofthe plunger-bolt are preferably provided with rollers for the purpose of reducing friction. The plunger-bolt G has an arm or branch, g, which,wl1en the parts are in position on a binder, extends downward by one side of the arms of the knotter-frame and passes loo f as'shown in Fig. 4 of the drawings.

beyond and outside of a cross piece or bar,a, which joins the'loweror depressed ends ofthe sidearms,a,oftheknotteriframe. '.lhisbranchr g is bent so as to. pass along the cross-piece a von the outside thereof to the opposite side of the knetter-frame, as shown in Figs. 3 and 4 ofthe drawings.

The cord-holder E is provided at its back or underside withA aratchet-wheehe; A pawl, I, is pivoted to the depending arm of the plunger-bolt and arranged to engage with the teeth of the ratchet-wheel, being provided with any suitable spring, i, which operates to hold itin such engagement. As the plungerbolt is driven inward toward the wheel C by the cam on the wheel I-I, the pawl is carried bodily in the same direction, thereby rotating the disk cord-holder at the proper time,and for vthe usual purpose ot clamping` the cord. A springstop, e', is fastened to the knotteiframe and arranged to engage at its other end with the ratchet-wheel foi-the purpose of preventing any back movement ot the cordholder. The pawl, it will be noticed, is attached by a single firm pivot to a rigid part of the pl ungerbolt, and its form and location are such that the direction of the toe is nearly parallel with the plunger-bolt, and so the movement of the toe of the pawl is in a line nearly parallel with the movement of the plu n- -ger-bolt, and substantially tangential to the ratchet-wheel, its spring serving to keep it engaged with the ratchet-wheel, however, during this movement. At the eXtreme outer end of the arm g of the plunger-bolt there is a short stud or boss, g2, (shown in dotted lines in Fig. 4, of the drawings) above which is an angular plate, J, which is pivoted at one corner to t-he knotter-frame, and is provided with a radial slot, j, outside the pivot. The cutter J is attached to this plate, which serves as its holder, and the plate is connected to the stud g2 bya pin, g', passing through the radial slot,

.Obviously,the reciprocating movement ofthe plunger-bolt will vibrate this plate, and so give a corresponding motion to the cutter-edge sufticiently to cut the cord, and is arranged to do this at the proper moment. The cutter and its holder, obviously, Vmay be made in a single piece, if desired, instead of two pieces, as here shown, the gist of the improvement being the construction and arrangement oi' the devices whereby the cutter is operated directly and positively in all of its vibrations by the plunger-bolt.

I have shown and described above in `detail the construction and arrangement of special devices by means of which Ihave carried my invention into practical operation; but I do not wish to be understood as limiting myself to this particular construction and arrangement of devices in details,for obviously changes maybe made in this respect, and yet the main features of the invention be retained.

In providing means for reciprocating the plunger-bolt positivelyl I avoid the use of all springs, against 'the force of whichthe plunger-bolt must'be active in the ordinary construction, and there is no resistance to be overcome in the movement of this bolt,except the slight friction in its bearings and that occa-v sioned by the mechanism whichit-is employed to operate. 'f It will be seen,too,that the mecha'nism for operating theA cord-holder is very simple and so constructed and arranged that it must act with certainty and without liability to disarrangement. Here, too, there is no resistance of springs to overcome. 'The same is trueof the cutter. It is operated positively by a simple connection with the plunger-bolt and without the resistance of springs to be' overcome, and by its connection through the plunger-bolt with the other devices must work' vat the proper time.

v I obtain from my im provements, then, simplicity of construction,

ance to be overcome by the motive force. k

In an earlier lapplication of mine, No. 95,342, tiled May 18, 1883, there are some `devices somewhat similar to those here shown and described. In the said earlier application, howcertainty of action, and a reduction of resist ever, lthe cord-holder pawl or paw1-support is loose on the plunger-bolt, being connected to the latter by an eye, which provides for movement of this piece -on the bolt itself. In the.

present case it will be noticed that the pawl is pivoted to a rigid piece projecting fromthe plunger-bolt, and the latter is moved positively in both directions. I here disclaim all de- IOO vices shown in the said earlier application as 'A a part of my present improvement.

Having thus described my invention, what latter positively 'in each direction, substantially as described.
