Tn all whom it may concern: l

Be it known that l, HENRY E. PR1DMoRE,a

' citizen of the United stetee, residing et ohi- 4pivoted ytotore.

cago, iu the county of Cook and State of Illinois, have invented' certain new and useful Improvements in Grain-Binders, (for which Letters Patent No. 6,326 of the Kingdom of -Great Britain were granted as of thel year 1887, April 30, to my assignee, OyrusHfMa,

heretofore it has been necessary either to give the knottertwo revolutions in orderto bring the crossed ends-of the strands between' its jaws o1' else to cause the holder to carry these end strands around part way to meet 'the yjaws before they complete their' revolution.

This has been accomplished either by arranging the ordinary disk-holder in such position and actuating it in such direction that it carries the strandsaround from the' chin ofV the knotting-jaws toward and past their spindle,

bending them around the latter, so that they meet the jaws when the latter have finished about three-quarters of theirrevolution, or

'else by mounting the holder in a swil ing stock and carrying it away from the cor' -slot .after it has received the strands tobend themV substantially in V,the samemanner as above over the knetter-spindle to anticipate the com-Av ing around of the knotting-jaws.

My inventionv relates lin the main, but not... entirely, to improvements upon theviirzstJ-of .these two constructions. In ,carrying 1t out the knot-ter is mounted-inl bearings parallel with the face ofthe tyer-cam aud driven and controlled' by a gear-segment and delay--iiange thereon in the usual way. The h eelof its. jaw is acted upon by aixed cam toand closed,l byf'a spitting-can'n,i asthereopen it A j'nger ,prejects from that sideof the cord-slot away from the knetter-spindle toward yand underneath the crown of the knotter, and serves as a stop for the cordstrands inside of the knotter-jaws, which in their revolution carry the cord along the inner edge of this finger overlits endand around into a continuation of the, slot ou the outer side thereof, the side ot the cord-slot beneath the crown of the knetter lbeing pocketed or recessed to receive the end of this finger and underlying ity that the strands maybe prevented from slipping past until positively carried past by the revolution of the jaws. 4A holdy er-spindle is mounted in bearings beneath andl practically inthe plane of the ayer-cam, .seasto trend obliquely .inward and upward" past the knotter-spiudle, and at its upperv end said holder-spindle receives a pinion, whichenvgages with a peripheral flange on the tyeris cut away at a suitable point 4or points to intermittently actuate the pinion, as woulda wormfwheel. The lower and outer -endof the spindle outside of the knetter receives a holder-disk not differing materially, if at all, from 'those' heretofore use,d,andl otsuch diameter cam, `which' has latral jogs or dei'ections and that the periphery adjacent 'to thecord-slot 1 projects thereover'slightlyinto the'plane .in 8oj is considerably on the otherstd'e of thetyen- 4spindle lfrom said'. plane, so that the quarter which the cord ris laid, whileits axis of course..

In all modern binders a hood or delector composed of va flexible sheet of metal-one or more-is secured above the head of the elcvator and depends outwardly o.ver the grainl chute to direct the grain properly ward the binding-table. It has been custol ary to connect this hood or defleotor with the breastplate by means of a wooden bar or bridge rigidly bolted between the flanges ot' said breastplate and extending inward until its end rests upon and, it may be, partly depresses, the outer edge of said hood. Sometimes it is desirable that it should press upon the hood with greater' forcethan` at others, or else, owing to the bending of the hood or other causes, the

latter falls awayfrom the bridge,leaving a gap between, and in the jolting of the machine tends to whip up against it, resulting in injury to one or the other, or in rapid wear. I therefore make `this bridge-car I1" adjustable radially upon the bolt f, which secures it to the breast-plate, and in obtalning this capability of adjustment I prefer'to form the bar "of metal, providing it with a discular hub f', serrated on its inner face and matchingagainst an opposing serrated diskj'g, secured to the flange which receives said pivotal bolt at the inner end of the breast-plate, so, that by loosening the bolt the bridge-bar may be turned to bring its end higher or lower to bear against the deflector properly, and then upon tightening the bolt the serration will be caused fto engage and hold the bar firmly in the adl jnsted position.

In bearings in the hanger from the tyershaft, which serves, in addition to its function in supporting the breast-plate, as a housingfor the spindles ot' the tying-head,`is mounted the knotter-spindlc G, having atits upper end the usual bevel-.pinion g and de-l lay-shoe ql', the pinion engaging with a gearsection G upon the face of the tyer-cam, of

IIO

suiiicient length to give it a single revolution and the delay-shoe engaging as usual with a delay-flange. G2, extending around the Vcam from one end of the segment to the other. The lower end of the spindle has the usual rigid jaw g2 and pivoted jaw g3, the latter being provided at its heel end, outsideof the rigid jaw, with an anti-friction roller y* to engage with the fixed cam G3 upon the supportingstock, whereby the pivoted jaw is opened, and with the spring-cam G, whereby it is closed after passing oit of the fixed cam. The relation of the tyer-spindle and its delay-shoe to the gear-segment and flange and to the tyingjaws is such that upon each revolution of the tyer-cam these jaws are left in a position trending outwardly and somewhat obliquely in the direction of the cord-slot in the breastplate, that the knot may be readily stripped from them by the action of the ejector-armselasticity from a long plate spring G5, constituting its shank and depending ,parallel with the tye v-spindle from a seat g5 upon the stock,

between which and its lower end it receives an adjusting-screw g, whereby the pressure of the cam may be adjusted. Lest the transverse lev erage of the revolving knetter-at the lower ent may twist or disarrange the carn, it is slotted, as at g1, to receivea pin er flange g? from the stock, which, while not interfering with its play toward er away from the knotter-vspindle, will prevent lateral movement in the direction of its revolution.

Since the knetter stops with its jaws trending outward in the direction ef the extendedslot'in the breast-plate, provision has to be ymade tojobstruct this slet that the strands may not escape past the knotteruntil its revolution commences. Therefore a finger I'lis arranged to project from that side of the'slot away from the tyer-spindle toward and past th'egeneral line of the other side. which is recessed or pocketed, as at 7i, to receive the end of this finger, while the depending flange beneath is left unbroken or is continued by web knetter is in its position of rest; but when the knotter revolves these'strands are positively swept around, and, beingvbent over the web, are carried from the main slot H along and past the end of the tying-bill and into the extended portion h2 of said cord-slot on the other side of said finger. This extended portion is not er may not be directly in line withthe main portion of the slot, but is preferably arranged obliquely thereto at a slight angle, flaring from that side of the tying-spindle past which the binder-arm moves, and the knetter when it comes to rest stops with its jaws trending outward practically parallel with this extended-slot that it may cross the path of thecord, and that the strands may be laid upon itschin in the recession and accession of the binder-arm, and also that the knot may be wrenchedtherefrem by a direct pull when the discharge-arms come around to eject the bound sheaf.

For convenience in casting the breast-plate the stop-finger is made detachable therefrom, being formed integral with a plate H2, which fits inte a'seat hB-in the upper surface of the breast-plate at the appropriate side of the cord-slot and is secured by bolts h4, which may also serve to secure the foot of the knotter-stock or tyer-frame to said breast-plate.

On the other side of the helder-spindle from the cord slot through the breastplate the tyer-frame has an oblique bearing or bearings beneath the tyer-cain and practically in the same plane therewith or parallel with said plane. This receives the holder-spindle I of'suicient length to. bring its outer end seme distance outside of the knotter'aud. near tothe breast-plate and its innernend close to the periphery of the -tyer-cam' inside of the knetter. To said outer` end is pinned the holder-disk'K of the usual form and having herein for the purpose vof .this description four notches 7c equidistant from each other.

A boss K frornthe tyer-frame on the farther side of the cord-slot in the breast-plate affords a pivot for a holder-shoe K2, which passes beneath the disk and embraces slightly more thanthe space between tweof its notches. The shank of this shoe is curved, as at lc,se as to receive and deflect the cord inte the receptive notch of the disk, and it is pressed against the periphery of the disk by a spring k2, adjustable in stress by means of an adjusting-screw las, acting upon its end. The diameter of the holder-disk is such thatits periphlery where it first meets the shoe is over the cord-slot in the breast-plate and'practically in the plane in Vwhich the cord 'is laid, and as its axis is en the other side of the tyer-spindle 'from this-plane and beneath the tyer-cani it will generally be depressed at the lowest point in its periphery below the surfaceof the breast-plate, which for this reason is cutaway,

as shown, to receive the shoe andthe disk.

Since the helder-disk must turn toward the shoe which first meets itat about itshorizontal diameter, and since it has but four IDO notches, it follows that it will make aquarter of a turn in the aggregate for each bindingl operation, and that, receiving the cord strands at one end of its horizontal diameter, it will carry them down to the lower end of its vertical diameter, which will be 4directly or a1- inest directly beneath the tyer-cam, and there-v fore a marked distance to that side of the tyer-spindle and jaws. Hence these strands will be wrapped or bent definitely around the tyer-spindle by this movement-of the holder, so thatthe tyer-jaws will meet them upon completing about three-quarters of a revolut'ion, and being already opened by their `fixed cam, which is slightly in precedence .of its usual location, they will pass en each side of them and immediately closing will grasp them. The cerd strands or ends from the knot are, however, severed slightly before the helder-disk .completes its quarter-revolution and just after they are seized by the tyingjaws, this being accomplished by a knife L, secured tothe shank of the holder-shoe by means of a longitudinal slot Zand clampingbelt Z, s'o that it may be adjusted to compensate for wearer to properly time it. The end of this knife is turned up toward the axis of the helder disk, against the inner side of which it comes, and form-ed with a. cuttingedge Z2, which intercepts the cord-strands just in advance of the stoppage of the disk or just before it has completed its quarter-revolution,

IIO

the disk, so as to have an interval of delay after an eight of a turn. This pinion engages with a rib or fiangeN upon the periphery of the tyer-eam, having an initial oblique reach or., succeeded for a distance corresponding with the interval between the severing of the cord and the starting of the tyer and hold er in the ensuing binding operation by a reach n',

so described as to act as a delay-ledge and hold the pinion stationary and tlre V,holderdisk consequently immovable, this at a-point corresponding,r relatively to the initial movement of the knotter, being followed by a short ledge N', having at the outset an4 initial oblique reach n2, which gives the i. tial movement tothe holder-pinion, turning it the distance of one toothor one-eighth of a revolution, then has a straight reach n3, which holds Ait stationary until the knotter has completed about three-quarters of its revolution and its jaws are passing or about to pass on each side of the cord-strands or end strands, wfhen it delivers the pinionA to the oblique initial reach of the first flange, by which the pinion is turned another tooth, completing the'quarter-revolutipn of the holder-disk, carrying the cord-strands nally home between the open knotting-jaws and shearing them against the knife and severing them, when both knetter and holder stop and the discharge-arms strike the bound sheaf and sweep it from the machine, pulling the knot from the holder-'jaws in so doing.

Since the holder-pinion is turned by oblique flanges or by a worm motion and intermittently held stationary by straight flanges it is evident that either the interdental spaces must be of a generally oblique trend or else the teeth must be set so far apart as to ac-` commodate both the straight reach and the oblique reach of the actuating-flange, whichever happens for the moment to be passing through. It is impractical to set them thus far apart, because it would lead to wabbling and defective action, and were the flanks and faces of theteeth set oblique to the axis ofthe pinion from side to side the wear from the oblique reaches of the actuating-flange, which imposes all the laboron the pinion, being distributed through the wholewidth of the tooth would aiect the engagement of the straight or delay flange, causing it to become loose and therefore fail to hold the pinion steady. .The straight fla-nge also would have only an edge of each of the two flanking-teeth to bear upon in performing its otiiceandwoulditself rapidly wear away these edges. I thereforeV cut the teeth O as regular spur-teeth with their faces parallel with the axisto admit the straight reaches of the actuating-flange. Then from about the center of the teeth, measured from the sides of the wheel, I bevel the faces. and flanks to alternate sides at an anglel corresponding with the oblique reaches of the actuating-flange. The retreating faces and flanks are beveled toward that side of the pinionY which first receives the oblique reaches, and the advancing faces and flanks are beveled toward that side from which said reaches de part. Thus the straight reaches of the actuating-fiange are received between two parallei straight faces of successive teeth, one f the faces o extending to half the thickness of the advancing face of its toothon that side of the wheel from which the flange approaches and the other face o diagonally opposite extending to one-half the thickness of its tooth on thatside from which the flange departs, while the oblique reaches engage with oblique faces of -opposing teeth, one oblique face o2 extending from the straight face of its tooth or from the center of said tooth on the retreating face to that side of the pinion from which the oblique reach approaches and the other oblique face o3 diagonally opposite upon. the retreating face of the other tooth, extending from the straight tace of that tooth to the side from which the oblique reach of the flange departs. By this construction the oblique faces of these teeth`,lwhich receive practically all the labor and all the wear,n1ay be worn away untiltheyhave eaten up allor nearly allot the straight faces withoutatfecting the steadiness of the engagement between the'straight reaches of the flange and said pinion, so that if an oblique reach should rest loosely in the interdental spaces of the teeth and fail to turn theless be turned to that distance as the succeeding straight reach enters between the IOO vthe pinion the proper distance it will never- 'teeth and thereafter held stationary until the Y coming around of another oblique reach.
