SPECIFICATION forming part of Reissuecl Letters Patent No. 10,003, dated January 3, 1852.

Original No. 183,813, dated October 31, 1876.

To all whom it may concern:

Be it known that I, DANIEL MGPHERSON, of Caledonia, Livingston county, State of New York, have invented new and useful Improve- 5 ments in Binders for Harvesters, of which the following is a specification.

The object of this invention is to simplify and improve the construction and operation of antomatic or self-binding attachmcnts.to har- IO vesters, and it is more particularly adapted to the use of wire for bands; butmany of its parts may be usefully employed in the construction of cord-binders. I Y

The improvements consist in mounting the binder-arm or needle upon a rocking frame or support and causing it to rock inward toward or over the graintable, descend, carryingt-he band around the gavel, which it separates from the incoming stream of grain, and then rock outward and discharge the bound bundle; in mounting the binding-a1 1n and hand-securing "mechanism to rock in unison, and so actuating them that the gavel is gathered and encircled by the descent of the binder-arm at the zs' eud of the inwardtraversmandthe ends of the band united by the operation of the band securing mechanism as the arm is pushing the gavel be 'ore it and toward the dischargingpoint on the outward traverse; in a compressor 0 of improved construction to compress and give form to the bundle and to relieve the band and band-applying devices of this duty and ot' the strain incidentthereto; in mechanism for causing the needle or binder-arm and compressor 5 to act upon the grain; in arranging and cansing the pinion of the band-fastening devices to be rotated bya toothed surface concentric with the axis of movement of the swinging support of the binder-arm or needle; iii-mounting the 40 binder-arm or needle and the band-tastening devices upon a common supporting bar or frame adapted to be rocked to vary the relation of said parts to the binding-table for the purpose of applying the band at the proper point to lengths of grain; in means for rockin g sai support or frame; in a supplemental receiver arranged to rock with the binding mechanism; in a. stop or abutment to prevent the bound bundle from movinginward with Application for reissue filed May '28, 1881.

the needle or binder-arm, and to insure its proper delivery from the machine; in themechanism by which the various movements are produced and controlled, and in details and combinations hereinafter explained.

In the accompanying drawings, Figure 1 is a front elevation of a harvester provided with my improved binding attachment, the barvester being partially broken away; Fig. 2, a side elevation; Fig. 3, a plan view with the re ceivers removed; Figs. 4 and 5, respectively, edge antt face views of the secondary receiver; Figs. 6, 7, 8, 9, and 10, views illustrating details of the twisting and holding devices; Figs. 11, 12, 13, 14, and 15, views showing details of the devices for operating the needle or binder-arm frame; Fig. 16, a detached view of the sector with the twisting devices in their forward position; Figs.17,18, and 19, views illustrating details of the compressing devices; Figs. 20 and- 21,- front and rear views of the sector; Figs. 22, 23, and 24, detail views of the devices attached to the sector; Figs. 25 and 26, detail views of-thedever by which the position of the binder-frame is adjusted.

The binding attachment herein described is designed to be applied to a harvestingma chine provided with a grain carrier and elevator, which may be of any of the forms now in use, and are therefore not shown or described, and the frame-work will be constructed in any suitable manner for such purpose.

Referring to the drawings, A A A A represent the frame-work of a harvester, of which the part A may be used as apart of an elevator-frame, over which the grain would be delivered to a fixed receiver, B, constituting the binding table or platform. For convenience of description such a construction will be understood.

The harvester frame may be sustained or supported upon the axle E of the main wheel D by hangers or brackets E E provided with journals, as shown, or in any other suitable manner.

tacle or binding-table B, is encircled and bound, the gavel being separated from the incoming stream of grain by a needle or binder-arm, T,

The grain, as it is delivered into the recep- 5 which swings inward over the receiver, de-

. scends through the grain, carrying the band about the same and to the fastening devices beneath the receiver, and then swings outward, pushing the gavel before it, and finally discharging it as abound bundle from the machine. To permit these movements of the needle or binder-arm, the latter is carried by a swinging support or frame, consisting of a shaft, M, upon which the needle or arm T is rigidly secured, rods N O, in the outer ends of which said shaft isjournaled, and a shaft, 1, by which said arms are carried, and which rocks in hearings upon a beam or cross-bar, Z, supported upon the harvester. This swinging or rocking frame is advanced and withdrawn to carry the binder-arm in and out over the grain-reccptacle by means of a crank, m, at the end of the axle E, connected through a pitman, it, having swiveled or jointed couplings at its ends, with a post,Y, firmly attached to the rock-shaft I, carrying the arms or uprights N O of said frame. As the post is lifted by the pitinan n, the frame, carrying with it the needle or binder-arm, is advanced, and it advances or recedes according to the revolution of the crank m, the binder-arm being raised at the end of its outward traverse and held in its raised position to clear the grain in the receptacle during the inward traverse, then, at the end of the latter, caused to descend to pierce the stream of grain and separate the gavel therefrom, and held in its depressed position during the outward traverse by mechanism which will be hereinafter described.

It is found in practice that when the bundle is compressed by the binding wire very strong devices are necessary for holding the wire for that purpose, and the difficulty of cutting and twisting is greatly increased. For this reason I compress the bundle into shape by a separate and distinct mechanism, so as to avoid the strain on the binding-wire necessary for that purpose.

The shaft M of the swinging frame is provided with a collar or sleeve, M, carrying an arm or bracket, Q, and permanently attached to the arm or bar N to prevent turning, and upon this collar or tube the spool or reel is placed when the machine is assembled for use. At the end of the arm or bracket Q there is pivoted a bar or compressor-arm, R, the upper arm of which is connected by a link or rod, S, with the binder-arm or needle, while its lower end is perforated, as indicated.

The binder-arm or needleTis firmly attached to the shaft M, as shown, and is extended backward to the rear thereof, either by a separate bar, U, or, if desired, by an integral continua.- tion or extension of the arm. At the lower end of the bar U is permanently attached aspring, V, to which spring and to the front end of the needle a cord or wire, W, is secured, s..id cord, or wire passing in its course from the spring,

to the needle through the eye in the pivoted arm R, which may be provided, if desired, with an anti-friction wheel to prevent the wearing of the cord. The rod or link-S being pivoted to the binder-arm or needle T and to the upper or heel end of the bar or compressor-arm R, and the arm Q being relatively stationary, the depression of the binder-arm or needle T at the end of its inward stroke or traverse will advance the lower end of the bar or compressorarm, so as to bring the points of support of the compressing-cord XV up to the sides of the bundle, around which said cord at the time extends from the arm R to the point of arm T, in which position the bar or compressor-arm remains until the bundle is bound and carried back ready to be discharged, when it again opens or returns to the position shown in Fig. l with the rise of the binder-arm. By thus compressing the bundle by a separate device, but very little strain comes upon the bindingwire, so that it can be held in position with a slight gripe and twisted without the difficulty heretofore encountered when the binding material was used as a compressor.

The spring V prevents the device from being too rigid and enables it to adapt itself to dilferent-szed bundles, so that it will properly compress either large or small bundles, and so that all sizes of handles will be bound with about the same compression and give the binding material about the same strain in each.

In order to give the needle or binder-arm T a positivemovement to raise or depress it, as the case may be, atthe termination of its outward and inward traverse, and to apply sufficient force to the compressor as the needle or arm.passes around the bundle, the shaft M, upon which the needle is secured, is furnished with a crank, L, connected by a pitman, K, with a crank-plate, J, carried upon the shaft I, upon which the needle or binding arm frame or support rocks, the plate J being formed with two spurs or points and controlled and actuated by other parts during the movements of the rocking frame with the needle or arm. As the frame swings inward the pivot of the pitman K, or its point ofconnection with the plate J, is above that of the rocking frame, causing the needle to be elevated, the pitman passing to or slightly beyond a vertical position over its pivot. The shaft 1 has also runningloosely thereupon a pinion, I, driven by a wheel, H,

on a parallel shaft, J, which is carried in bearings Z Z on the bar Z, and is in turn driven by miter-wheels F G from the axle E. The wheel H has two blank spaces or sections, as shown atv, Figs. 1- and 13, and two sections of teeth. At the commencement of each toothed part there are side projecting pins u. These pins engage alternately with the points of the plate J, which plate is attached to the pinion I, so as to move therewith, and has the pitman K pivoted to itatadistance from its own pivot or axis of movement.

As the wheel H is revolved by means of the position shown in Fig. 1, one of the pins u strikes the projecting point of the plate J, re-

,miter-wheel .G, and as the rocking frame nears the termination of its inward stroke from the volving the plate and drawing the pituian K forward or downward until the pin passes the point, when the motion is continued by theintermeshing of the teeth of the wheel with those of the pinion I, to which the plate J is firmly attached, as above stated. This imparts a downward movement to the binder-arm '1, continuing until the needle is bronghtcloseagainst the tying-head or band fastening devices and the rocking frame is about to start on its return stroke, at which moment one of the blank sections 7) of the wheel H reaches a blank space, 20, ot' the pinion I, made by leaving out two or three of the cogs, and locks therein, so that the needleis held and remains in its depressed position during said returnstroke and until the second pin strikes theopposite projection of the plate J,when the crank. L is elevated and the parts are again in the position from which they started.

By cutting out the sections 11 of wheel H the pinion I may be left entire; but to insure uniformity and certainty in the action I prefer to;

make the wheels as described.

The post Y is provided with or carries the band fastening or twisting devices, which. are

operated by a toothed rack concentric with theaxis about which said post moves. These tie-- vices consist principally of a rotating twisting hook orfinger, e, fast upon a shaft, c,provided with a pinion, b, a clamping-wheeler holder, (I, mounted upon said shaft as a pivot, a cut ter, f, fast to the shaft, like the twister, and located a short distance behind the latter, so as to follow it and cut. the ends of the wire bahind it after they have been graspedi in the twisting movement, and a bar or gate, g,.slid-.. ing in ways in the head Y and pressed for.- ward bya spring, h, into a normally-closed position to cut off the access of the wire tolt-he twister. As the post moves inward and=outr ward the pinion b is made to. revolve bythc teeth of the curved rack X, described uponaan. arc concentric with the axis ot' movement of; the rocking frame and post, and carriedhy or mounted upon the bar or beam Z, whichteeth. inthe outward movement of the postdrivetha twistingand cutting devices in the proper di? rection for their purpose. the limit of its inward movement the pitman- K, operating upon the crank L and operated:

by the crank-section of the plate J, as above.

described, depresses the needle or bindcrsanm T, and causes it to pass through the opening; ot'the receiver and to comein contact with the tying or twisting devices in the head Y.. The advance orinward movementof the parts also brings the opening of the spring bolt, bar, or

gate 9, for holding the wire ontof the twister while it is passing over the sector, inicontactz with the incline j on the post In, which-draws the bar back and permitsthe wire at thel'iropermoment to pass it and enter the twister. Near the farthest point of advance of the post-Y one of the projections or teeth of the clamping-wheel d comes in contact with a bent post or stop, I, which causes theavhecl to turn one step, in

As the. post nears;

which position it remains, being held by the spring or click, as shown in Figs. 6 and 9, acting upon the teeth of a ratchet-wheel secured to the under side of the clamping-wheel until the succeeding inward stroke or advance is made, when it is moved another step, and so on, for the purpose of folding the spool or ieel end-of tllGNYliB against orinto a shou der or loop, d, so it will pay ott' from said reel as it comes-against andis carried around the gavel.

The head Y of the tying or twisting device is provided with a concave, t, in which the twisting device revolves. The twister 0 lies close against the surface of this concave opening, and consequently snubs the band endsot' the wire thereagaiust as it gathers them in, and holds them afterthey have been severed from the-spool portion and while they are being twisted together. The cutterf, movingin unison with and close behind the twister, seversthexbamlends from the spool portion immediately. after they have-been snubbed, leaving the endof saidrspool portion securely held bythe clamping-wheel, which has by this time graspediihas above explained.

It .isdesirable tha the gavel should be bound as-near the middle. ail-practicable, and as grain variesin-length- Ito-rigid fixturecan bind the different lengths suitably. Fon this reason the cross-bar Z is pivotally supported upon the axleEofthe; main drive-wheel D, near the-bracket orisupportEl, and to thiscrossvbar the bindingtdewicesarc attached; At: the side oflrthis balanced bar Z are attarhedthe journahboarings ot the shaftJ", and they are so areanguhthatthe wheelG will retain its proper geaniuwhichevcn direction-the bar Z may be tilted;

If-Lhe'bindingtapparatus were permanently, fixed? inany given position,- the receiver B wouldbesufiicieutfonalhthe purposes of reeeivingthe grain; but as said deviees are made adjustahlel have made-a large opening, asshown,. in the-receiverB, and placed immediatclyi holowthisa secondary-receiver, G, which istprovidedwith an opening onlysuflicient for the operation ofthe binding. devices. This ITS secondary receiver is permanently attached to the tilting bar Z, and it moves from side to side of the large opening in the receiver B, according to the tilting of said bar, maintaining at all times the same relation to the bind-- ing devices. The secondary receiver serves to close the large opening in the main receiver, and to immediately cover the hand holding and uniting mechanism. The main receiver is carried sufficientlyfar around to protect the tying devices and to insure the delivrry oi the bundles upon the ground. It is supported at its lower end by the bars D, attached to the main frame at A The bars D may, if desired, be considerably longer, and thereby shorten the closed portion of the receiver R, which may also, ifdesired, be made in strips its entire length instead of closed, asshown, and it may be considerably shorter.

The secondary receiver should be made to fit as close against the main receiver as is practicable and not interfere with its tilting. The secondary receiver is provided with a spring-bar, P, which springs down as the bundle passes over it, and returns to position as soon as the bundle has passed, thereby preventing the return of the bundle or its stick ing, so as to interfere with the compressor or other parts of the machinery.

In operation,.as the machine is drawn along the cut grain is delivered by means of an ele-. vator over on therecei-ver B. As the machine advances the crank m tilts the frame upon which the compressing-arm and the needleor binder-arm T are supported, and moves it forward or inward to position, when the plate J and wheel loperate to di ive the needle through the accumulated grain and bring it down and around to the twister. The wire or cord W, passing over the grain, acts as a compressor, and, with the described operation of the baror compressor-arm R, brings itinto com pact shape forbiuding. Thehindiug-wire passesfromthe reel on the sleeve M, through the opening or eye near thepointof the needle, to a point just below the head Y, then-up past the uniting mechanism andaround thegavel to the holder, as will be understood. As the-head comes in contact with the arm 1 the spur-wheeld advancesoue step and c, tches the strand of wire from the needle and holds it over one of its projections in theform ot a loop. The crank am having no 7 --.ssed its-dead-center, the rocking frame begins to mov e rack to'w ard'the outer side of the machine The first movement of the twisting-finger ged oy the engagement ofits pinion with the cc-i. grasps the ends of the wires and holds t eu friction between said finger and the-cones i of the head Y, immediately succeeding which they are cut by the bladef. Then, the revolution of the twister continuing, the bundle is brought to its discharge-point-and the binding-arm rises for its return-stroke.
