-GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 261,072, dated July 11, 1882.

Appiiaum inea February 7, 1882; (No model.)

To all whom it may concern:

Be it known that I, JOHNF. APPLEBY, of Minneapolis, in the county of Hennepin and State of Minnesota, 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, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a novel m'ethod of and means for eecting the tripping into operation of the binder devices or binding mechanism proper in that class of grain-binders in which the mechanism for encircling the gavel with a band of some sort remains at rest during the packing into the gavel-receptacle of the requisite quantity of grain to form a sheaf, and is then automatically set in motion or put into operation from some continuously-running motive device of the harvester.

` Previous to my present invention it was common to operate the tripping device or mechanism of snchimachines-that is, the device or mechanism for throwing the binding mechanism.; into gear with thecontinuously-running driving device of the harvester-by or from some device or part of the machine against which the grain in the gevel-receptacle was compacted, and which device, bya movement induced by a pressure of the grain, operated to actuate other parts or devices for throwing the binder mechanism into gear and thus into operation; but all such heretofore-employed means for the purpose alluded to have been found more or lessimperfectin practice, mainly because of 'the liability (under the varyingconditions vof the grain, &c.) of the binder mechanism being set into operation either at the wrong time or with-the collected gavelv in the wrong position relatively to the binder devices proper.

Myinvention has for its main object to provide a better mode of and means for eectuating the throwing into operation of the binding mechanism; and to this main end and object it consists in the employment of the cord or I other sheaf encircling and banding material vr for actuating the tripping device, said cord operating' at the proper time and byreason of the pressure upon it of the gavel collected within, its loop, (preparatory to' 'the encircle'- meut of said gavel by said cord,) while it is held fast at or beyond both ends of the loop, all as will be hereinafter more fullyexplained; and my possible, all as will be hereinafter more fully explained.

To enable those skilled in the art to which my invention relates to understand and practice it, I will now proceed to fully explain the mode so far known to me as the best for carrying out my said inventiou,and in which I have so far successfully practiced it.

In the 'accompanying drawings, forming part of this specification, I have shown at Figure 1 in'end view so much of a harvesterbinder as seems to be necessary to illustrate my present improvements in such machines, and at Fig. 2 in Side view the same mechanism. Fig.3is a partial or skeleton view taken from the saine point of sight as Fig. 1, but showing only a few of the parts seen at Fig. 1, while Fig. et is an elevation of the parts `shown at Fig. 3, viewed in the direction indicated by the arrow at the lastmentioned `figure. In all the figures the same part will be found designated by the same letter of reference.

For the purposes of illustrating my present improvements I have shown them applied to a machine substantially such as is made the subject of United States Letters Patent granted to me, No. 212,420, and which, somewhat improved, is known as the Appleby b1nder: I need not particularly refer to or explain -any of the mechanism shown in the drawings,

except that which embodies or is necessary to the operation of my present invention.

Instead of using a tripping-finger located near the outer side of the gavel-receptacle and connected by intermediate devices with the arm P, as heretofore, I now move said arm by the following-named means: A is a bar adjustably connected near its upper end (by a clamping-nut, c) and a stud passing through IOO -jectin g from the axis of the spur-gear F ofthe binder, and said lower portion of bar A isformed or provided with an arm, h, the bent lower end, i, of which passes below and across the plane of vibration of the trip-arm P, all in such manner that if the bar A be moved bodily in'the direction indicated by the arrow at Fig. 411, and to a sufficient extent, the bent part t' of its arm portion h will first come into contact with and will then move the trip-arm I on its axis of vibration, and thus release the dog Q of the clutch mechanism in a manner and for a purpose well understood.

, The proper movement of bar A (in the man-` ner just alluded to) is effected by the vibration l about its axis b of the lever just mentioned,

the longer end C thereof mov-ing in the direction indicated by the arrow, (see Fig. 1,) and the return of the parts to their original posi- 1ione(seen at Fig. 1) is elfected by a movement otl said lever inthe opposite direction. lhis lever is moved in one direction by the cordD, as I will presently explain, and in the other direction by a-spiral spring, Gr, one end of which'is fastened to the 'longer arm C of said lever and the other hto the cord box or receptacle H, all as plainly'- illustrated in the drawings.

I isa bent lever which turns at its angular part, having there a stud or axis, j, mounted in afstand or bracket, k, made fast to the binderframe. The upper arm of this bent lever has secured to it a rod, J, which extends upward, and is fastened at its upperend to the tension device of the cord-box, while the lower end of said lever I is so shaped and located as to be acted upon by the pitman of the spur-gear E of the binder in a manner that I will presently explain.

The tension device on the 'cord-box II cons-ists of a fixed projectionyor plate,` m, beneath which the cord passes from the hole in the box, and a movable or clamping arm, n, located'beneath the cord, and between which and plate m the cord is squeezed more or less, as circumstances require.

The arm nis pivoted ato, (to the metal bracket p, which carries the plate m,) audit is held up toward the plate m, so as to pinch the cord D f between itself and said plate m, by a spring,

s, which acts against the end of a set-screw, t,

in the lug 7' ot' 'bracket p, all in a manner well.

understood by those familiar with the Appleby binder.

Projecting from the arm n of the tension device is a bar, n2, to which is secured the upper end of rod J, and whenever this rod may be pulled in the direction indicated by the arrow at Fig. 1 the -eect or result must be to clamp the lcord D between the arm n and the plate m more or less tightly.

L is an adjustable stop,which, being set-in the proper position, predetermines the position to which the longer arm C of the lever B C shall be pulled by the spiral spring G.

With what has already been said, and the following explanation, in connection with the drawings, of the operations'i-ot the different parts, I think my invention will be fully understood.

Supposing,.now, that the parts of the machine are in the relative positions seen at Fig. 1, and that the binding mechanism properhas just come to a position of rest, the cord D, one

end ot' which is held fast in the cord-holderat S, will extend iu nearly astraight line from S to the eye of the needle-arm, and, passing from the needle-arm, will run through the usual stationaryguide-eyes at V and W, and thence eye in the end ot' the arm C of lever B C, and thence to the cord -box H, as clearly shown. As the grain is fed and packed down on top of the cord D and in the gavel receptacle by thepackers in the well known manner the cord D (that partof it -beneath the grain) must perforce be pressed down into a hooplike condition by the grain but as the cord is now securely clamped between and held fast bythe arm n and plate m of the tension device (in consequence of the pull of the rod J on arm n2) that part of the cord taken up by the eyedend of arm C must be paid out in order to form the loop for the accommodation of the grain, and as this previously-taken-up portion of D is paid out the arm C is of course pulled down until its eye nearly or quite reaches the locality of the eyes 1 andl 2. This movement of the arm C, which is completed at just -runs through two fixed eyes, 1 and 2, and the IOO the right time, causes the shorter arm B to l neath dog Q, setting the binder mechanism proper into motion. As soon as this occurs the pitman K, moving from the positionseen in Fig. 1 toward that seen in dotted line at Fig. 3, releases the .lower end of bent lever I, and that lever assumes the position shown by the dotted lines at Fig. 4, thus permitting the cord D to pull through the tension device and. pay out, as may be required, in the operation of encircling the gavel and tying the cord. While the tension device is still left in this condition,"the spring Gr next operates to draw the longl arm C of the lever B C back to its original position against the stop I, and thus the requisite amount of cord is again pulled from the cord-box (through the tension device) to permit a repetition of the operations just described when another gavel is to be bound 5 and at this time the pitman K will have returned to the position seen at Fig. 1, (the gear E having made one revolution,) and will again act on the lower end-of the bent lever I, causing it to resume its original position, and

IIO

senese a through the ineda already described to effect the reclampin-g and holding fast of the cord D at the point where the latter passes through the tension device ofthe cord-box.

Of course, so far as the primary feature of my invention is concerned-wiz., the employment of the cord to pull on some device when,

.itself acted on by the grain for starting the binding mechanism proper into operationany othersuitable means than those shown may be devised and used for imparting the pull on the cord (caused by the compactin g of the grain against it) to devices for throwing the binding mechanism into gear and into operation.

What I claim as new, and desire to secure by Letters Patent, is-

1. In that kind of grain-binders in which the binder mechanism properisperiodically thrown into gearwith some continuously-running motive device or part ot' -the harvester, the combination, with the cord or other banding maf terial, the said binder mechanism proper,` and the said motive device, of a device or contrivance which operates to throw the said motive device into engagement with the said binder mechanism proper, and which is actuated by 3. The combination, with the binder mech anism, the mechanism for starting the same, and the banding cord'or other material, of a mechanismy consisting essentially of an actuating-lever connected'at one end. to the starting mechanism and operated on at the other by the cord, a spring for returning said lever to its place, and a stop to regulate the amount of cord taken up by the said lever at each op- `eration of the binder, asset forth.

Witness my hand this 12th day of December, 1881. y

JOHN F. APPLEBY.
