IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part ofuLctters l'a'tcnt No. datcd'lfccemlwr'', 18559tlleissneae-Sy99-l, dated December 9, 1879; application iiled September G, 1879.

To all 'whom it may concern:

13e it known that I, SYLVANUs D. LooKn, formerly of J anesrille, Rock county, State of Wisconsin, but now of Hoosick Falls, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Machines for Binding' Grain, of which the following' is a speciiication.

My invention consists in a rotary twister formed with radial peripheral teeth, into which the wire is thrown directly for twisting, and by the engagement of which the twister is driven; in supporting such twister upon the ends of the teeth by which itl twists and is driven; in wire-holdingand 4wire-cutting mechanism for grain-binders, and in the various combinations hereinafter' described and claimed.

In the drawings, Figures l, 2, and 3 are side views, showin g one mode of constructing the mechanism for operating my iin-prove- 4ments, together with certain of the positions which said mechanism and the binding-wire assume during the operation of binding. Fig. 4 is a front View ofthe twister and its casing. Fig. 5 is a sect-ion of the same, taken upon a horizontal line through Fig. 4, and'including the wirecutting and wire-holding devices. Figs. 6, 7, and 8 are rear views ot thetwister and its easing, with the wire-cutting and wireholding devices intervened, and showing the different positions of these several parts and of the binding-wire during the opera-tion of binding. Fig. 9 is an elevation, in detail, of the rotary part of the cutting mechanism. Fig. 10 is an elevation, in detail, of the converse part of the cutting mechanism attached.

to and carried by the twister. Figs. 1l and 12 are sections of the cutting and holding mechanism, showing how the binding-wire is cut and the end held. Figs. 13 and 14 are under-side views yof the binding -head and gear-wheel shown in Figs. l, 2, and 3, illustrating the manner in which the twisting, cutting, and holding devices are operated. Fig. 16 is an elevation, in detail, of the rotary part ot' the wire-holder. Figs. 15, 17, and lo are side yviews with the inclosingshell support in section, showing-the dili'erent positions of the several parts and of the binding-wire duringthe operation of binding.

A and A are cam-arms, pivoted at a, and operating, respectively, the twisting-arm B and the armG, which carries the binding-head. On the twisting-arm is a curved rack, D, playing in a pinion attached to the gear-wheel E', that turns on the stud c on the arm C. To the latter arm is attached the segmental gear F, which meshes with the segmental pinion Gr, pivoted at g, and having attached the third or band-carrying arm, H.

I is the grain-guard; J, the binding-platform or grain-receptacle; K, the reelfor bean ing the binding material, and L the bindingwire.

All the mechanism is actuated, primarily, by the crankM, that plays in the cam-grooves b b in the cam-arms A and A. The 'form ot' these cam-grooves is such as lto giveto the ai's'BT, 'and {iE-thermovementshereiuafterv described, as will be more fully understood by reference to Letters Patent No. 97,531,grau'ted me December 7, 1869, of even date with the patentof which this' is a reissue. l l

N is the twister,-'for u1ed like a pinionhthe interdental spaces being of suiiicient depth to admit the -wire .between their bottoms and] p the crests of the in'termeshing gear-teeth', so that each tooth may serve at once as a twisting-arm and a leaf or cog for driving the twister, and each intcrdental space as a slot for receiving; the wire. The twister is here' shown as slightly be'velechbut may be a spurpiuion in sha-pe. It takes bearing only upon4 the ends of its teeth in the parts dd of the inclosing-shell, which parts are attached to-- gether by screws, as shown, or otherwise, and secured in any suitable manner to the hand c ofthe arm C. This shell is slittedat'a' to admit the wire to the twistingpinion, and so formed as to leave both ends of the pinion and the inner portions'of the teeth .and indentations fully exposed to give a space through'I which the wire may gyrate while being twisted. The pinion is operated by the gear-wheel y E, which has access tp it through-a slot or y opening in one side of the casing, as represented in` the. iirst three figures, and, among others, iu Fig. 13, the teeth ofthe gear-wheel meshing' directly with the 4 twisting-teeth of the pinion through said slot.

Firmiy attached to the outer ena 0f the twisting-pinion, by rivets or otherwise, is a plate, m, that is, as to its edge, a knife, against which the .radial blades ej g h of the rotary cutter O (shown in detail in Fig. 9) alternately work after the manner of shears to cut or i sever the wire, and which, as to its side face,

is ajaw, against which the radial arms j k l of the. rotary holderr P alternately press the wire, so as tov thereby hold the cut orfree end. The circular body of the vrotary holder is recessed, as shown 'more particularly in-A Fig. 16, to receive the circular body of the rotary cutter, into which recess the latter is so far in- "sertedas to leave vbetween the radial arms of clamped together and pressed against their converse part upon the pinion, with whichlat ter they revolve during the twisting operation. The bolt is held from turning in the pinion, and thus loosening the nut, by means of `a pin, 0, passing through the two. This bolt gives bearing to the rotary holder and cutter, and allows them to be readily adjustr ed, by means ot" its nut 'and the use of washersbetween the parts, vat any desired distance from the platem, carried by the twister, so as f to.4 permit the use of any desired size of wire.

0n the face of the gear-wheel, and in the patli traced by the rotary holder, is a dog or latch, Q, Figs. 13 and 14, swinging upon the vertical pivot q, and held by the spring r against the lugr4 or projecting'portion` s of the wheel. This dog serves asa stop to the cntter` and holderin their revolution with the t\visting -}')ini'on so -that in the latter part of thetwistingoperationthepinion maybe driven past them to sever the wire, as hereinafter more fully described.

To operate the machine., thc various parts .being in the positionl shown by Fig. l, theend of the binding-wireL is carried from the rcel K on or along the arm H, passed through an eye or guide in, the point of 'the latter, and then,being taken into and through the month a' of the shell dd', and between the teeth tot' v the pinion N, and lplaced around one ofthe radial arms, )',ofy the rotary part of thel wireholder, it is inserted betweenl another radial' arm, k, andthe converse part or plate m, as fully' showninFigs. 1, 6', and 1 5.

The-.crank turning, asA indicated by the arrow, the arms; B' and@` open or separatey to allow thefgavelto bc-brouglit in on the platform' J againstthe guard I, when, the arms closing,

the bindingewie; is looped, as at L', around it,

.again free to revolve.

The relative position -of thel Wire-holding and wire-cutting mechanism and of the bindv and again' inserted in the teeth of the twisting-pinion, as shown in Figs. 2, 7, and 17.

Theform of the cam-grooves b b must be as shown in the drawings, so asl to canse the two ends of the wire passing around the gavel to be inserted in the teeth on opposite sides ot' the twisting-pinion, one end being laid in the teeth as the bandcarrying arm is withdrawn to .receive the fresh gavel, and the other upon its return to encircle this gavel', a half-'revolution being given the pinion in the interval by the divergencev of the cam-grooves.

The` wire lilaving .been passed around the gavel, and both ends being inserted in the teeth ofthe twisting-pinion, the crank, continuing to-rotate, is now compelled by the gravitatin'gblock u to pass into the upper groove of the cam in the arm A, drivingdown this arm, and, through the arm B and rack, operating the gear-wheel E, that, in turn,

i causes the pinion and the attached wire-hold ing and wire-cutting mechanism to rapidly revolvo, so twisting together the ends of the,

.wire, as represented in Fig.,18..

During the latter part of the twisting operation the movement of thev gear-whecl E in the direction. indicated by the arrow'in said figure carries the free end ot" the dog .underneath the revolving radial arms in such manner aste stop and move backward one of these arms, j, to the position beibreloc cnpied by the arm i.

The movement of the radial arms ward onlyrelativcly' to the revolution of the twistingpjnion, as the real ctt'ect of the dog is simply to stop the movement of the rotary parts ofthe wire-holding and wire-cutting d e vices nntil the movement ofthe pinion shall carry forward ovcrone of the/spaces between the radial arms thevcouverse part m, the arm striking the face of the dog or latch `and riding over it until `it drops ott' at the end, and is in g'wire before the di'erential movement just described is shown in Figs. 7 and 17, and their relative position after this. movement in Figs. 8 and 18.

The backward movenicntor stoppingxofthe wire-holding and wire-cutting mechanism in causing the radial arm l and radial blade h to take the position relative to the. plate -m,car ried by the twis'ting.pinion, respectively shown by the arm k and blade g in. Fig. `7, lirst forci bly doubles thercel end of the band between -the arm Z and the faceV of I`thevp'late, and then severs it from 'fthe gavely portionl by action of the blade h againsttheedge of the plate.'

In this. same movement, bywhiclr the new end of the wireA isseized andV cut, the arm k being. carried onward and away` from itsl former position over theA plate, the old end ot" thewire l.

When these arms 'have passed, the dog vis d riven..backb,\,' its` spring, and rests against its stop in readireturn in the actuate them and its plate.'
