IMPROVEMENT IN GRAIN-B INDERS.

. Specification forming part of Letters Patent No. 152,481, dated June 30, 1874; application tiled -May 13. 1874.

To alt whom 'it may couccm:

Be it known that I, JAMEs F. GORDON, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Self-Binding Harvesters; 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, in which- Figure l is a front elevation of my improved self-binding harvester, having the cutting-platform and reel broken away. Fig. 2 is a top sectional view of the binding apparatus and platform. Fig. 3 is a rear sectional elevation of the same. Fig. 4 is a detached top view of thcsaddle or hanger frame for the wire-clamping jaws, and showing the wire-relieving guard b. Fig. 5 is a detached inverted view of the twister-hook pinion and its rack o1. Fig. 6 is a view of the lower wireclamping jaw N3. Fig. 7 shows a modificaion of the switch-track, for operating the clamping-jaws. Fig. S is a front elevation ot' those portions shown in Fig. 1, but representing the binder-frame, &c., folded up, whereby the machine may be drawn throug'h an ordinary gateway. Fig. 9 is a sectional end view of the elevating-belt R, and showing a spring or yielding' carrier bolt or lug to catch the cross-bars t2 of the elevating-belt El. Fig. 10 is an elevation and a top View of the cushioned draft socket or lug of the crank-arin C. Fig. l1 is a top view of the end of the binderarm, showing the pivoted clearing-yoke o2. Fig. 12 is a detached view of the jacket J This invention consists more especially in mounting the binding mechanism upon a reciprocating frame; and the employment of an automatieally-locking device to govern the movements of the same, and in providing for the folding up of the said frame and its earrier-bars, for the purpose of permitting the machine to be driven through ordinary gateways; in greatly simplifying the method ot' operating the wire-clamping jaws and the twister 5 also, in providing' a sliding clutch to be under the constant and immediate control of the driver,.by means of which clutch the working parts of the binding apparatus may be either thrown into action or locked in any desired position while the other portions of the machine are in operation.

A represents the sill of the machine; A1 and A2, the supporting-braces of the upper portions thereof; B, the binder-arm; Bl, the fender-belt; B2, the brace which sustains the swinging end of the pivoted carrier-bars G, upon which the sliding or reciprocating frame F and F1 of the binding mechanism is supported; O, the binder-arm crank 5 O1, thedriving-crank, G2, the connection of said crankarms; O3, the connection of the locking-cam J and the said sliding frame; D, the conveyorslats 5 E, the guards, H, the cushioned draftstops for the crank-arms C; J, the metallic sheathing for the twister-frame; K and K, belt-rollers hung in the pivoted supportingbars Gr; L, cross or tie bars of the saine; M, jaws or ways between which the switch-roller c runs; N and N1, rods of the clamping-jaws; O, hangers of the binder-frame; P, face-plate of binder-jaws; Q, hinge-joint of the slats D; R, elevating roller 3 S, stirrups or roller-hangers ot' the sliding' frame 5 T, take-up leverfor the binding-wire; l/V, ground or driving wheel.

I use the same cutting and elevating mechanism in this case as that set forth in my patent of August 27, 1872, No. 130,852. The oarrier-slats D in this case are shaped about as shown in Figs. l and 2, one end being hinged to the upper end of the inclined bars or slats E, so as to permit them to be folded back, as indicated in Fig. S. A hanger, 7c', is detachably connected to the brace Al at t3, each side of the machine. These hangers are fixed to the ends of the cross-bar D3 and the supporting-blocks D1, to each one of which a slat, D, is ixed, and attached at proper distances to said cross-bar. The horizontal portion of the slats at the lower end are thereby suspended above the jacket or sheathing J on the sliding frame, and the interstices between the slats D are entirely open and unobstructed, as shown in Fig. 2, from the line where the binder-a-rm strikes in to the extremity of the slats D. The supporting-rails G are pivoted to the bar Gf at Z. These two side bars are framed together by means ot' two cross-bars or girts, L and L, Fig. 2, between the r 11ers iixed to the side of the take-up bar.

K and K. The bars Gr are provided with a track, S1, upon which the reciprocating binder rigidly iixed to the pivoted bars, and theirV ends rest in the sockets H2, when the frame is in its working position, as shown in Fig. l. The reciprocating binder-frame is composed of two side rails, F, and under the jacket J1 two cross-bars, F4, and the post Fl, the upper ends of lwhich latter are connected by a crossbar under the binder-arm shaft Y. This shaft is mounted in suitable boxes at the top of the posts Fl. The arm C is keyed to this shaft, so as to sustain yabout the relative arrangement to the binder-arm B as that shown by the full lines in Fig. l. The arm 13 may be made adj ustablelaterally across the machine, substantially the saine as in any ot' my former patents.` The take-up bar T is pivoted to the binder-arm, and at the lower end is provided with a roller, r, that bears against the curved plate I, which is tixed to the cross-girt at the top of the posts. This plate I should be of sufficient length to admit of any desired amount ot' change inthe adjustment of the' binder-arm. The wire-reel W I mount upon the take-up bar T. The latter is provided with a grooved pulley atan, also one at m2, and the binder-arm has a pulley at m1. The wire passes from the reel to the lroller m3, thence to m1, and from that to m2, and from that to the eye in the point of the binder-arm at x. Tile rod T1 is pivoted to the binder-arm near m1, and passes loosely through a loop The setnuts p may be adjusted so as to just rest upon the fixed loep through which the rod passes when the binder-arm is in its extreme downward position, and the rod is thereby made to hold a'ny spring brought upon the take-up bar by the strain of the wire when compressing a gavel, and thus prevent it from drawing through the end of the binderarm, or out ot' the grasp otl the clam ping-j aw, after being severed by the twister-hook.

1t will be seen that when the binder-arm is in the position of the dotted lilies at x, Fig. l, the wire-pulleys m1, m2, and mi" are very near each other, but as the arm descends these points are separated, which causes a quantity of wire to be reeled oft", (the end having heen previously passed through the eye of the arm 13 and fastened to the lower end of the same,) and when the arm has returned to its upper position the descending grain from between the slats D and the guards E will readily cause this slack toassume a curve similar to that indicated by the dotted curve z, and when the arm again descends to encircle the gavel with the wire the former is permitted to readily assume a round or cylindrical form.

Theinet-allic jacket or sheathing may be made in three or more sections, and the end one made to overlap thecentral section, which latter is movable with the twister-frame, and has an opening to admit the end ot' the binderarm with the wire. They are provided with open loops, as shown at q, Fig. 3, on each side, and these catch around the hooks or pins inserted in the bars F4 and a hasp-loop, u', Fig, l, over a staple, in which position the parts are secured by the hook p. The belt Bl is attached to the front and rear cross-bars F4 of the sliding frame, and passes over the rollers K and K. This belt may be made of ordinary canvas or any other suitable material, 'and is ldesigned to prevent straws, &c., from dropping into the wire-twisting apparatus and the clamping-jays and their operativemechanism.

There are several sustaining-iingers,Q, fixed to the rear bar F4 of the sliding frame, for the purpose of retaining one bundle, at least, upon the binding-frame until the next succeeding one is being encircled or compressed by or,

with the binding-wire, and thus insure a more perfect'separation. These iingers Q. might be fixed Vto a separate bar hung between the pivoted arms G, in rear ot' the belt-roller K, it' desired; or a close shelf might be employed, and attached in either position'.

The cushioned 'draft-loops H are bolted to the posts Fl of the sliding frame. They are made, as Yshown in Figs. 1 and 10, so as to receive the end ot' the crank-arms C when they are to draw the binder-frame in. The sockets S3 of these stops are preferably provided with a cushion, T2, of rubber, `felting, or other suitable material, to relieve the parts from the concussion otherwise produced by the end of the cranks C striking the socket.- A metallic spring would serve the same purpose.

The roller it, which is the driving-roller ofthe elevating-belt, I provide with several yielding carrier-bolts, 0, which consist of a small bolt having aslight enlargement orshoulder at such a distance from the outer end as to permit it to project through the plate which secures it in its place in the roller, and to catch against the cross-bar t2 of the elevator-belt E. This bolt is rendered yielding by means of a spring, s, whereby, it' a cross-bar should happen, as is liable to occur, to come upon the end ot' the said carrierbolt, as shown in Fig. J in i'ull lines, the spring would allow the bolt to re` tract, and thus avoid breaking or straining the belt.

The dividerfingers F2 may be curved, as shown in Fig. l; or they may be made of thin plates, constructed with a wide base, as indicated by the space between the curved line F2 and the dotted line Y. This latter shape would undoubtedly eti'ect a more perfect separation or division of the grain-stalks. These ngers are tixcd to a cross-bar extending from one arm, H3, to the opposite one. These are hung to the axial shaft of the elevator roller 1t, and are operated by a connecting rod, Z', which is driven -by a cam upon the shaft a.

The lingers F2 maybe iliade to work between tht slats D, or through openings in them made for that purpose.

TheA binder-arm B is operated, by means of the levers or crank-arms C, from the drivingcrank G1, through the connection C2. As will be seen, when the driving crank is at w the binding -arni would be at As the' crank passes up to wl the binder arm is carried down to xl,- and, when the crank reaches fw? the end of the binding arm has entered the twister-frame at we; and as the crank C1 moves beyond this point the bindingarm preventing the crank C from turning any farther upon its axis, the sliding carriage or binding-frame is thrown back to the position shown by heavy dotted lines. Then, as the drivin g-crank G1 moves toward 104 the en d ot' crank C is brought into the sockets S3 of the stirrups H, and raises the binding-arm to the upper' position, indicated at we; and when the crank C1 reaches the poiutw4 the reci procatingjframe is returned to the position shown in full lines. The binder-arm and twister should be adjusted so as to register to one et the openings between the slats D, which being opened out to the end ot' said slats, the end ofthe binder-arm is allowed to swing down into the twister-frame, and remain there while the frame F is thrown back;

and, furthermore, there is no obstruction to straws, &c.

It is obvious that, owing to the above described construction of these parts, whenever the cranks C were not in contact with the sockets S3, the reciprocating frame would be liable to 'move back or forth by the jostlings of the machine, &c., or when the gavel is being compressed or encircled by the binding arm. To prevent this, I provide the locking-cam J, which is shaped about as shown, and is pivoted to the sill of the machine at fu. per or swinging portion is connected, by the pitman or connection G3, to the sliding frame, whereby it is firmly held in the desired position at all times. l

Thile the crank is passing from 1r to Q02 the sliding` frame is at rest 5 and while it is passing from rcito 103 said frame'is thrown out, as indicated by the heavy dotted lines, where it again remains at restwhile the crank passes around to 104, and the frame is returned while the former is swinging from 7a4 to ir.

It being desirable to enable the driver to ,throw the binding mechanism into or out ot' gear or operation` at any time, I provide a sort of double clutch, or one that will lock the parts in a fixed positionwhen those parts arethrowi'i out of gear with the driving-wheel, so as to prevent a retrograde or a continuous forward movement of the binding mechanism.

The clutch u', preferably having V-shaped teeth, is lixed to the box X; and when the binding machinery is to be thrown out of operation while the harvester is still moving, the clutch u on the main axle would be thrown clear over, so as to lock into the fixed clutch The up- 11', whereby, through the bevel gears ll1 and the locking-guard J, the parts are all firmly held in a fixed position. This ratcheted locking-clutch u may be operated by any ordinary system of bell-cranks and levers extending to a convenient position near the drivers seat, to be operated by either his hand or his foot in one direction, and be moved in the opposite way by a counteracting spring, or otherwise.

The shaft 'nf and locking-cam J may be hung higher up in the machine, it' desired, by any suitable arrangement of gears and shaiting, to prevent the lower portion of the cam'y or guard, and also the crank l during that portion ofthe sweep ot`,the.latter, from dropping below the sill ofthe machine.

The stock M', Fig. 2, to which is attached the wire-clampiugiaws and twisting mechanism, is hung between the cross grts or bars Fiotl the reciprocating' binding-frame by means ot' the looped hangers O, which permit the stock to be adjusted to an y desired position laterally across the machine, and, at the same time, serve as 'a tie between the bars F4.

A It will be seen vthat the twisting apparatus 1n this case occupies a horizontal position instead ot' vertical or inclined, as in my former patent before mentioned.

Thevwire-clamping jaws are made and arranged to operate substantially the same as set forth in my application filed February 21, 1874, except the rearpor under jaw N2, which I now make as shown in Fig. G. This construction of that jaw has been `found to work far more satisfactorily than as formerly made. The point of thejawv at al being shortened so as to be entirely withdrawn from the fixed jaw indicated by the line (1?,causes it to eii'ectually discharge any fragment of wire or severed ends otl the band at each stroke or operation ot' the jaw. The endgof the wire is looped around the nger f2, and forced thereby against, and partially into, the cavity in the fixed jaw, whereby it is lirmly held while the binder-arm rises toits open position to receive a bundle or gavel, and while it is encircling the succeeding gavel with wire,

I have found that during the time the binderframe is returning to receive each succeeding gavel, there was a liability of the backward revolutions of the twister-hook, which takes place at the same time, to cut off the wire thus strained across the track of the points thereof. This I obviate by means of the bar b, Fig. 4, pivoted to the under side lof the faceplate l. This bar constitutes asort of bellcrank, and the opposite larm b is slotted, as shown, or otherwise connected with apivot on ,the arm or rod N ot' the jaw a., so, that when ion r', the former being carried or sustained in the hanger V, by which it is suspendedbeof the full-liner arrow the direction of rotation of the hook is reversed. The rack is made a very little shorter than the distancc'between the bars L and L', which affords a short interval of rest for the twister-hook at the end of each rcciprocation, more than is occupied by the frame-that is, the frame moves a short distance either way in commencing a returnstroke, carrying the rack with it, before the end of the latter strikes the bar L or L. This distance, 'as indicated at c', Fig. 2, may be made more or lessv according to the length of time the twister is desired to remain at rest, which is for the purpose of enabling the wireclamping jaws to act-the upper one to grasp the ends ofthe encircling-bami, and the lower one to release the wire previously held by it before the twister commences its revolutions.

The wire-clamping jaws a and N2 are connected with, and operated by, the rods N and N1, and their springs, which are relatively arranged the same as those shown in myformer application iiled February 2l, 1874, but the rods are actuated in the following manner.

To the under side of the stock M is bolted a hanger-plate, S2, Figs. 2 and 3, which sustains a narrow bed-plate, d, that extends nearly from bar L to L', as shown in Fig. 2. This plate d is fitted to slide freely in its track or bearing` in the hanger, but as its length is but little less than the dista-nce between the said bars, its longitudinal movement is only sufticient to permit of the automatic changes of the switch, more fully described hereafter, yet allowing the stock M and the hanger S2 to be easily reciproeated by the sliding frame.

The plate It is pivoted to the bed-plate d. at y.' Said plate It is provided with a socket, y1, which sustains that end of' the shipper-rod f1, and the opposite end passes through and has a bearing .in the lug c2.y This rod should be of such a length that it and the shipper-plate t shall just measure the distance between the bars L and L, whereby thc axial point of the switch g is prevented from. moving forward with the plate d as the frame and stock M start to move in the direction ot' the dotted arrow. This change of relative position of the switch and the lug s2 nnhooks and relieves the former from the latter.

The track t is lixed to the plate el in the position shown, and at the opposite end of the plate is pivoted the star-wheel or switch j, which is permitted vto revolve in the direction of the arrow, but is prevented from turning in the opposite direction by the spring dog or pawl y2.

f The lever connecting the rods N and N1 is provided at the lower end with rollers e and el. VThe roller c works between the jaws M of lthe stock Mr. The roller e4 travels either side of the track t in the following'mannerz As y the stock moves in the direction of the dotted arrow, Fig. 2, the several parts occupy their position, as shown in full lines. When the roller c4 arrives at the point m it comes 1n contact with an arm or point of the starwheel or switch j, which turns and carries the roller to the position indicated by the dotted circle at a, Fig. 2, and as'the stock M starts in the directionindicated by thefull-line arrow the roller is forced over upon the other side of the track, as indicated by the dotted lines e3, the lever swinging in the end ot the rod 'or spindle N1 as a fulcrum, the upper end of thc'lever assuming the position indicated by the dotted lines at i', which withdraws t-he rod N and opens the upper jaw a.. The lug o on the hanger S2 strikes the lug c1 on the rod f about the time the roller reaches the point m, and draws the switch g up in the line indicated by the dotted lilies, and when the stock M starts to move toward the bar L the bed-plate d is carried with it until the end strikes against said bar, and this movement, it will be seen, forces the plate lt into the position indicated by the dotted lines, and thus causes the end ofthe switch to catch upon the lug s2. The roller e4 Atravels upon the righthand side ot' the track, as shown at c3, holding the upper jaw open and the other closed until it arrives at the point 7c, where it drops into the curved depression in the switch-arm gf, which is for the purpose ot' permitting the arm b to drop back out ot' the way ofthe wire and' twister-hook. Then, as the opposite reciprocationvof the stock M commences, the plate d moves with it until the end strikes the bar L, and the rod f1 preventing that end of the plate lt from following, the switch-arm gy is unhooked from the lug s2, and the roller c4 is forced up the inclined plane to the point I., which closes vthe upper jaw aand opens the lower one. The same position ot' the roller c* is represented by the dotted lines c2 in Fig. 3, the upper rod becoming the fulcrum in this case, and the lower one, N', being withdrawn, as indicated by the dotted lines at fi.. Since the lower jaw only requires to be open for a short interval, the roller c4 is immediately allowed to return to its normal position, and the va-rious operations are repeated. The movements of the jaws and their actuating mechanism must be timed tocorrespond witlrthose of* the binder-arm, &c. Instead of the automatically-aeting switch g and the several devices for voperating it, a tolerabl y satisfactory result may be attained by means of a simple guiding-track, t,tiXed to the bed (l, Fig. 7. Thelower end of the brace B2 may be locked to the socket H2 by a hook or other suitable means. The guard or clearing yoke o2 may be composed of a single plate bent in the form ot' a bow, and the ends pivoted near the end of the binder-arm, as shown in Figs. 1 and 1l,

and it is forced to the position shown by the full lines by the spring h2, except when the binder arm enters the twister, when it is hroughtinto the position indicated by the dotted linesinFig. 1. This deviceis designed to prevent the side projections r2 from catching in the straws when entering the grain,

rlhe machine is folded up, as shown in Fig.

8, to perlnit it to be drawn through gateways by removing` the bolts lf', when the parts can he swung into the position shown in said Fig. S. lt might be desirable to suspend the twisterrack o and the bed-plate (l, either or both, from the bars L and L by having the ends rest in suitable mortises, or on brackets, or otherwise.

To insure the proper delivery of the bound bundle from the horizontal portion of the slats D I provide the brackets d, which are preferably attached to the jacket J as shown in Fig. l2. They are shaped as shown to enable them to be readily carried under the grain or gavel as the binder-frame moves forward; but to insure their catching the bundle when itv moves back, and to discharge the same from the slats, there may be one or more fixed to each of the end jackets, and they should be so arranged as to register to the interstiees be tween the slats.

The operation, briefly stated, is as follows: The cut grain, after bein g elevated, is delivered to the binding apparat-us upon the horizontal portion ofthe slatsD. The end of the bindingwire having been previously adjusted in the twister, and secured by the lower clamping-j aw, the reciprocating frame moves to the position indicated by the full lilies in Fic. l. The end of the binder-arm being at .c the slack wire before described is readily forced back by the accumulating grain, and as the arm descends and enters the twister `just a sufficient quantity of wire is reeled oif to encircle the compressed bundle, whether it be large or small. The ends of the encircling-band are twisted together, while the reciprocating frame is being thrown to the position indicated by the heavy dotted lines, Fig. 1, at which time the arm is again raised, the bound bundle still remaining upon the frame, which tends to trim up the grain in the next gavelas the reciprocating frame moves forward for it. It is found that this keeps the gavels truer and makes the separation more perfect, because the grainstalks are more or less overlapping each side of the binder-arm, and when the lastbound bundle is dropping from the frame, before the next succeeding one is bound, the division is liable to be imperfectly effected, there being more or less slobber in the operation, especially if the grain is lodged or tangled but when the last bundle remains nntil the next is being compressed or bound each takes its own when they part.

If there should be no gavel to be bound when the arm descends at any time the slack wire will be temporarily taken up, as before shown, by that movement of the parts, and as the arm rises it will be again released. The quantity of this slack wire may lbe regulated by using a longer or shorter take-up lever, or by changing the relative position of the wire pulleys m1, m2, and m3. These pulleys should all have some sort of a guard-loop to prevent them from unthreadin g.

I use a wind-board similar to that set forth in my said former patent, but in this construeton of the machine I prefer to attach it to the pivoted side bars (zr. Instead of the locking-cam J the connection C might be provided with a toggle-joint, and t-he end now attached to the cam J be pivoted to the side bar Gr. This would lock the binding-frame in its outer position until the joint was tripped, which might be done by a lug fixed to the pitman G2. The frame might be locked into its inner position by a similar togglejointed lever, having one end pivoted to the cross-bar L, Fig. 2, and the other to a lug fixed to the under side of bar F4. This lever should fold horizontally after being tripped. Instead of the star-wheel j a pivoted bell-crank switch, similar to g and g', might be employed, and connected. thereto by the rodf, whereby either would receive its adjustment from the other alternately. Instead of the brakets d a pivoted bar, with rake-teeth arranged to rise and fall by the reciprocations of the binding fram c or carriage, might be employed.
