To' all whom it may concern Be it known that I, DANIEL MOPHERSON, of Caledonia, in the county oi' Livingston and State of` New York, have iniven-tedcertain ylm provements in .l Machines for Binding Grain', of which the following isa specification My invention relates to a combi-nation of devices for binding grain with wire, and is intended to be4 appliedV to an ordinary reapingmachineat` the inner end, andI to .the rear, of

theV cutter-bar.

ln the drawings, Figure l `represents a plan view of my invention. j Fig. 2 is a planview of the twisting device, shown removed'from thel frame ot' the binder. u those parts to the left oftheldolttedline m, Fig. 2.

These kslides arek located atl right angles, orfnearly so, to the `linger-bar of the reaper. l (Shownin dottedlines in Fi'g.,1.) `The cross-head Dis reciprocated, by 4means of the crank G,` upon the driving-'shaft E', andy-ods@ and e, connected` respectively tothe upperand lower ends of `the vi brating` lever f, thencrV and the cross-head.v Therake-barBf; ispivot` ed toavertical post,d, which has, bearings in the cross:head1D",yand. is' provided, at its lower` end, with acrank and wrist,'g, Figs. 9 andtlO. The wrist works in a sinuous slot, h, formed in` the plate f.

Itfwillbe seen thatas the cross-head `is reciprocated by the revolutions of thecran'k C,

the rake Bis swung around on the post d .toV the position indicated by dottedlines in Fig. l,

and'i'ull lines inFig. 9,'by means of the crank g and sinuous slot y The slidesa are `supported upon a frame, F, which, in turn, moves upon slides j, secured to the frame A at right angles, or nearly-so, tothe slides a. A hand-lever, G,'Fi'gs. 1 and Fig. 3 is an elevation of ank;

10controlsthe position of the-frame F upon the guides by means of? a suitable connecting` lin k; The object of this' arrangementis to so` adjust the termination of the sweep oi' the rake B astthat' the grain' shall -be delivered upon the auxiliary platform H: in a position to receive the band 'at the center, Whether the straw be long or short. The rake B ispivoted, at Aor near its center,to the bar B, Figs. 1` and- .,9, and the inner end is guided by a projecting tongue of thebrace cWhifch-brace is hinged, at itslower end, Vto the post d. The bur B" passesthrough a slot'in this brace, aseshown insection in Fig. 9, and is connected t'o it by a bolt'.` `or pin, d', sliding horizontally in a slot; in bar B", and also in a shorter slot in the brace c. The arm Bll and rake B-are supported by thel braoeof, as shown, and whenv they are in their lower position, are held'down by the latch e",

hinged: to the post d, and hookingA over a pin or `lug on the brace.` When, however, the

Vrake andt *cross-headv are forced back yto their"- rear positions, by means of the crank' C `and connections, the inclined lower edge of the latch e comes in contact with vthe tripper j", fixed to the frame F, which raises the` latch and leaves the rake free to rise, while, at the same instant, the latte-r iselevated by means" of thelu g against whi'chthe'bracec strikes y ,y g 7 i causing the rake-and bar B" tovrise, as ,indi cated by dotted lines inFig. 9.

i The rake is retainedjin this position -by ratchet-teeth h formedupon the bar B" and` engaging, w-ithga hook on paw] xed 1to1 the brace c. While elevatedthe rakeisjreturned to its forwardpositionand swung around" parallel with the cutter-bar, as shown in-Fig.1. Thislatter operation brings theL brace cinto contact/with the camishaped projection l,

Figs. l and 9, upon the cross-head D, which' pushes thejbraoe out ofl the ratchet-teetli` h and allows the rake to fall;

To ease theV blow ofthe rake upon the plait-J form, Ilprovidea spring-latch, m', Figs.ll,.9, and 10, which catches theproje'cting end 4 of the` bar B" as` the rake descends, as indicated bydotted lines in Fig. 10. This latch'is'pivoted to a post, m", which has a vertical movement in guides xed lto the crosshead*D,gsucl1 movement being controlled by an irregular slot, n, formed 'in the side4 of the frame F, into which a lug on the post projects. Y Just as the latch m catches the endof the bar B, the post m" begins to rise, by means of the slot a", allowing the rake to descend gradually upon the platform. When, however, the cross-head D arrives at the forward extremity of its stroke, the projecting arm p" trips the latch and the rake is left free. It may be desirable to attach a stud, 4, to the end of the rake-head B, working in a slot in the brace c', as shown. This retains the rake in a certain position relatively to the bar B, and still allows them to rise freely.

For they purpose of collecting and compressing the bundle upon the platform H, l provide the gathering-rake J, the arm k of which is pivoted upon the chain-belt L by a suitable stud. They upper end of the rake-arm is hingedto a link, m, which, in turn, is hinged to a fixed portion ofthe frame A. The chainbelt L passes over the driving-wheel a and guide-pulleys o and p, the latter of which is located somewhere above the line of the peripheries of n and o, whereby the rake J .is elevated clear of the platform El as it returns to the rear. The belt L is operated by shafts q and r, connected to the driving-shaft by suitable gearing. J thus sweeps over the platform H during its forward movement, and is lifted away from it during its return-stroke, the bar 7c being guided and retained by the link m.

The platform H is curved upward slightly at the forward end, as shown in Fig. 9, so as to be iiush with the surface of the cap-plate a of the twisting device, and, to cause the rake to accommodate itself to this inequality,l make the teeth's separate from the rake-head, and fitted to-slide in suitable bearings provided thereon, as shown in Fig. l2.

The wire-bar I, Figs. 1 and 9, the lower end of which is shown alsoin Figs. 3 and 5, has a vertical movement in guides t, secured to the frame A, and isv operated by the segmental gear lvLvworking in a rack upon the face of the bar I, and connected to the crank C by a link, u. The wire drawn from the' reel N passes through a slot infthe lower end of the bar I, as indicated by the heavy line in Fig. 5, which bar, at each descent, carries the wire,

previously pressed around the bundle, to the twisting device.

The adjustment and proportion of the parts which drive the rakes B and J and wire-barI are such that the rake B delivers the grain from the reaper upon the platform H just as J begins its stroke thereon, and the latter gathers the bundle upon the plate a just as the wire-bar descends and draws the wire around the bundle. lt will, however, be necessary that the movement of the rake J cease for an instant while the wire-bar is descending, and,- to accomplish this, the gear S, which drives the belt L, is loose upon the shaft E, and connected to it by a sliding clutch, 0, Figs. l and l0. This clutch is thrown out for a certain portion of each revolution of the shaft E by means of the revolving cam b and shifter P.

lt will be seen that the rakel A link, R, one end of which is fitted into a sinA uous groove in the periphery of the cam, is pivoted to the shifter P, Iand said camv is so adjusted upon the shaft E that the clutch is thrown out at the moment that the rake J arrives at its forward position.

Since the cam b' is so formed asto allow the clutch O to pass but one tooth when thrown out, the proportion of the revolution in which the gear S remains still, depends upon the number of teeth in the clutch, and the proportion of the gear to its pinion S and chain-belt L must be such that the speed of the rake J shall be accelerated sufficiently through the remaining portion of its movement to return it in time for the descent of the wire-bar, as before.

I attach a collar, b, Fig. 1, to either ofthe shafts q or r, provided with a pin or lug probolt, a", moves in suitable guides upon the frame A, and being beveled off at the outer end from below, it is forced back at each revolution of the shaft by the lug upon b. As the lug passes, the bolt springs back under it, and the clutch O being thrown out at this juncture, the shafts q and r, belt L, and rake J are thus prevented from being forced back by thel pressure of the bundle upon the latter. I do not, however, wish to be confined to the construction or location of the locking device here shown, as other similar arrangements maybe used to answer the same purpose. Neither is it essential that the clutch O and connections be attached to the driving-shaft E, since it may be placed upon any of the shafts used to operate the parts.

lt is found desirable to use, in connection lwith the rake J, the auxiliary compressionarm T, which I pivot to the frame of the machine and operate bya slide, R', Figs. 9 and l0, and cord d, running over suitable pulleys. The slide R moves vertically upon a guide,

a, placed parallel to the wire-bar I, and ai spring-latch, i, Fig. l0, pivoted tov the slide,

catches under a lug formed upon the wire- `bar, by which, as the latter descends, the slide is also carried down. This movement forces the curved arm T down upon the bundle while ,the wire is being drawn around it by the bar jI. As the latter reaches the lower part of its stroke and the wire is caught by the twister, the latch t" is unlocked from the bar by means of the incline 2 upon the lower end of the guide w, releasing' the slide R and arm T, which are returned to, their places by the -spring lc', Fig. 9. The spring la", attached to the a-rm T and cord d, allows the compressor to adapt itself to different-sized bundles.

. The twisting apparatus is located imme- 'diately under the wire-bar I, and is covered by the cap-plate a', Figs. 5, 7, and 9, upon which the bundle rests Vduring the process of binding. The plate a is omitted in Figs. 2, 3, 4, and 8, to show the parts underneath.

The lever B', Figs. 2 and 3, is pivoted to the frame A of the twisting apparatus, and is jecting from its face or periphery. A springtightly against the hook j.

ruimer y e provided with a slot near its outer end, in

which a wrist-pin, upon an arm of the bevel segmental gear C,iworks. The segment C imparts motion to the twister-head D by i means of the horizontalshaft e and suitable p bevel-gears, as seen `in Figs. 4 and 5. Thev lever B has a spur, j?, upon its upper edge, of

such alength that'the` wire-bar I passes freely `place when the wire-bar rises.

A stop, t', forced inu byfa spring, locks under the spur j" and prevents the bar B from dropping by the jar of the machine. When the wire-bar descends it pushes out the stop, the inner end of which is beveled off for that purpose. The twister-head D is scroll-shaped, and is provided with the hook j upon one side, which catches the wire4 carried down by the wire bar as the head begins to revolve. rlhe pivoted jawl, Figs. 2, 4, and 6, moves in-a recess formed in the twister-head, and when `swung around by the cam "'rt', as shown by dotted 'lines in Fig. 6, itA clamps the wire A finger upon the cam nf comes in contact with the yielding dog 10', Figs. 2 and 5, by which the cam is given a part of a revolution for the purpose `of clamping" the wire; i When the wire-bar I rises,` lifting the lever B', the motion of the head D is reversed andthe finger of the cam is tripped in the opposite direction by the dog y p andthe jaw L opened to release the wire.

It will be observed that the cam a is located onthe opposite side ofthe twister-head from the hook j', and the position of the dog p being the same with reference to the wirebar, the wires are clamped at thevsame instant that they are caught bythe hook.

Below the twister D I' provide cutters q r', Fig. 8, r being pivoted to the fixed plate q and operated by the cam-plate t', Figs. 2 and 3, attached to thefoscillating lever B. Thehook u', pivoted toa portion of the frame. A, gathers the wire between the cutters and into the jaws of the twister just as the latter closesand the cam t is so arranged as to operate the knife rbatiabout` the same time, whereby thetwister is left f ree to revolve with the ends of the ywire firmly clamped in it.

The gathering-hook u is worked by the wire-bar, which acts in itsdescent on the inj clined face of the slide c', Fig. 3, and forces it outward,carrying with. it bent arm lw', which` is suitably attached tothe hook. A spring C returns the slide and hook to their original position, and another opens the jaw y.

It will be seen by reference to Flg. 3 that the end of the lever B4 and lower edge of the fixed guide g forma clamp for the lower end ofthe wire while the bundle is being formed, the wire taking the direction shown in Figs. 3 and 5. After the wire is cut of, that part projecting from the lower end of the wire-bar is left bent up close to' the bar, as indicated `by heavy and dotted lines in Fig. 5. For the purpose of straightening this end, I provide the oscillating stripper-arm wf, Figs. 3 and 5, having a sharp or rounded loweredge. This `arm has bearings in the frame A', and its lower edge is retained against the face of the `wire-bar by a spring, and it is so located that the bent end of the wire passes it when the bar I descends, but when the latter ascends the wire is bent down so as to be caught by ythe clamp B g and securelyheld.`

The reel N has a bearing upon a post, N,at

`a suiicient distance above the frame A, and

Vto its arms q are pivoted the adjustable arms c carrying Ys at their outer extremity to receive the coil of wire. The arms c fold over, as indicated by dotted lines in Fig. 9, whereby .the coil may be placed upon them without winding o. The pivots s slide in slots yformed in the arms q", and the inner faces of c are provided with ratchet-teeth, in which the spring-pawls` t engage. The reel may lthus be adjusted to a coil of wire of any diameter. It may be desirable to use the arrange lnent of arms shown in Fig. l1, in which the 'arms c slide in the tubular arm g, the adjustment being secured by a set-screw, as shown.

If convenient, the arms c" may fold in a direction at right angles to that shown.

The chain u, Figs. l and l0, worked by a ehainor gear from the shaft E and moving parallel, or nearly so, with the frame A', is provided with a spur, y, which. being properly timed, sweeps the bundle off at the side of the machine as soon as bound. An opening, 3, is provided in the cap-plate a', which admits the wire-bar easily, and a conical cavity or countersink is formed around it, upon the also formed in this plate extending tothe center of the twister-head, which allows the wire to be drawn to such center to be twisted.

The operation of my invention is as follows: Powerbeing communicated from the groundwheel of the reaper to the shaft E, the rake B drops into the grain upon tl'eplatform and carries it around to the auxiliary platform H, when the rake is raised by thearation of the lug g upon the brace c. Just as the grain is delivered upon the platform H, the rake J ,drops upon the latter and gathers the bundle upon the cap-plate a', while the wire, which Ahas been previously put through the slot in" b throws out the clutch O, allowing the motion of J to cease till the wire-bar enters the opening 3 in the cap-plate. The wire is thus drawn entirely around the bundle, as indicated in Fig. 5, and as the bar I passes through the 4 I 10m/ov opening in the cap-plate, the latch y is pressed against the wire, and by its friction checks the latter and controls its tension around the bundle. The double Wire is next caught by the gatheringhook u and pushed into the cutting-jaws q r' and also Z j of the twister, which latter, at its first quarter-revolution, clamps the ends of the wire just before they are cut o. The head D then makes two or more turns, by means of the lever B and segment C', securely twisting the wire together. Meanwhile the bar I ascends, reversing the motion of D and releasing the band, while the end projecting from the wire-bar is turned down by the stripper 4rc and caught in the clamp B g, ready for the next bundle.

The spur y" now pushes the bundle offupon the ground, and the rakes B and J complete their movements and return, as before.

It will be observed that all the parts of the twisting device are operated by the descent of the wire-bar. By this arrangement l dispense with the apparatus necessary to operate these parts from the driveshaft, and insure their movement in exacttime with the wire bar. It may be found preferable to attach the segment G directly to the lever B', thus dispensing with its two bearings.

In place of thechain u/and spur y, I may use a bent arm operated in the proper time by some moving part of the machine, and if dcsir able the compression-rake J may be worked by a lever or crank instead of the belt L.
