IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 198,104, dated December 11, 1877; application filed October 25, 1877.

To all whom it may concern 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 Grain-Binders, which improvements are fully set forth in the following specification, reference being had to the 'accompanyin g drawings.

. Figure l is a rear elevation of a portion of a machine to which my inventions are attached. Fig. 2 is a plan view of the same; Fig. 3, a side elevation, looking in the direction of the arrow 1 in Fig. 1. .Fig. .4 is a front elevation,

drawn to a reduced scale, showing pickers e 0, &c. Fig. 51s an enlarged sectional view of .the twister'head H, looking in the direc tion of the arrow 51 in Fig. 2, showing the twister t, &c.; Fig. 6, a plan view of the twister-head H, showing the top portion of the twister t uncovered, the pawl 11 &c. Fig.

7 shows the twister, with the binding-wire in two positions, the view being taken as indicated by the arrow 3 Fig. 6. Fig. 8 shows the twister t, binding-arm B, and several positions of the binding-wire, the view taken as I in" Fig. 7. Fig. 9 shows the wire-clamping jaws j and j, the view taken in the direction 'of the arrow 3 in Fig. 5. Fig. 10 shows the wires clamped between the clamping-jaws j and centering-plates a over the center of the twister t, the view taken as in Fig. 6. Fig. 11 shows the lower portion of the twister uncovered, and the point at which the wire is out. Fig. 12 shows the annular pointed guard '6 partially covering the lower portion of the verse section of Fig. 15, as indicated by the dotted line .90 and arrow y". Figs. 19 and 20 show the compressor attachment 0 re-engaging the compressing-cord 0 Fig. 21 shows the manner of hanging the frame upon the the grain, as it is cut, is bound by the operation of the machine. 7

The nature of the improvement consists in the employment of a compressingcord and friction-drum, and in connection therewith novel mechanical means by which the cord is caused to encircle and compress the gavels, and automatically release the same,and at the same time bring the cord into position to compress each successive gavel, as will be hereinafter more fully explained; in providing the binding-arm with a driving mechanism, by which it has a period of rest from its vertical reciprocation during the binding of each gavel; in providing a twister by which the wire is-relieved from strain while being twisted, and in other improvements which will be explained farther on.

Referring to the drawings, Ais the frame and W the driving-wheel of areaper, in which the cut grain is carried up over the drivingwheel, as indicated by the arrows f, and deposited in the receptacle 13. Motion is communicated to the long pinion P from the driving-wheel by means of intermediate gearing a and the chain 0, as shown in Figs. 1 and 2.

'The gear G is driven by the pinion P, by.

means of which and the lever L and connecting-rod R the binding-arm and the rest of the binding mechanism are operated in a manner similar to that shown and described in my former patents.

The binder-armB, Fig. 3, is formed with a slot, cl, and the bracket g, which is rigidly fastened to the bifurcated head 0, has a slot of a similar width, the upper end of which bends toward the right. The bracket g and that part of the binder-arm containing the slot cl stand side by side, parallel, and a little distance apart; and in the'space between them, Fig. 1, the upper end of the connectingrod R is inserted, with its cross-pm or roller 0, extending either way through the said slots. As the connecting-rod R presses upward, the pin 6 moves up along the perpendicular portion of the slot in the bracket g, moving the x the wire.

binder-arm till the slot cl of the same coincides with the inclined portion of the slot in the bracket, (see dotted position,) when the vertical motion of the binder-arm ceases. While the hub c is carried along the lower portion of the wheel G the pin e moves up the inclined portion of the slot in g, and no vertical motion of the binder-arm results until the said pin returns to the angle in the slot and commences to descend. By means of this arrangement the point of the binder-arm and the twisting device are kept relatively at rest while the ends of the wire are-being twisted, and during the outward vibration of the binder-arm and twister-carrier.

k, the twister-carrier is supported and stead ied in its horizontal vibrations. The stud k extends downward from the under surface of the twister-carrier (J, and supports at its lower end in a horizontal position the gear G which, at intervals, revolves the twister-pinion p.

The gear G is provided with-curved slots, two of which are seen at s and s, Fig. 2; and n is a bar pivoted upon the stud k, resting upon the gear G, which is provided with a fixed pin, 1', that reaches downward into the slot '8, 86C. The slotted connecting-bar a is pivoted to the fixed bar a at 0, and rests upon the bar a, to which it is movably attached. by means of the headed pin 1", as shown.

As the twister-carrier O swings in the direc-v tion indicated by the arrow y, the pin r glides outward along the slot .9 till it reaches the end 7 of the same, as shown in the adjacent dotted position, when the gear G is caused to revolve sufficiently to cause the-twister-pinion p to make several revolutions,sufficient to twist When the twister-carrier moves in the opposite direction, the pin 1 slides back to the opposite end of the slot 8 at which point its motion is arrested, in consequence of which the bar at is forced around its center 70. As the pin r is brought by this motion of the bar n to the end of the curved slot 8, it slides up the inclined of the same, Fig. 14., and rides on the surface of the gear G until it drops into the next slot 8 Now, when the twistercarrier 0 again swings in the direction shown by the arrow y sufficiently far to bring the pin 4" to the end of the slot 8, as above described, the gear G is caused to turn, as before, by the pin 1 pressing the end of the curved slot. The pawl 10 engages a tooth of the gear G, and prevents any backward motion of the same which might tend to take place as the pin ris forced up the incline a, as above mentioned.

The gear G, by the means above mentioned, is caused to move on its axis intermittently,

. the periods of motion occurring when the wire is brought into position to be twisted together upon each successive sheaf.

The twister I design to use is shown in plan at t, Fig.- 6, being a series of hooks, and in elevation in Fig.7 and other figures. It is divided into an' upper and lower portion by the annular groove a in which groove is inserted the pointed annular guard 6 Figs. 6 and 12. Fig. 12 shows this guard unobstructed and partially covering the lower portion of the twister t, the upper portion of the twister being shown in section. The twister t is attached to the upper end of a vertical shaft, at the lower end of which is fastened thepinion p, as shown in Figs. 5 and 9, the said pinion 19 being intermittently revolved by the gear G, as above described.

The pawl 19 as shown in Fig. 6, and in the general view, Fig. 2, is attached to the fixed bar 12 against which pawl a tooth of the gear G is brought just before the twister-head H reaches .the limit of its throw toward the driving-wheel W. This turns the gear G slightly upon its axis, just sufficient to give the pinion p and twister about one-half a revolution, the use of which will presently be seen.

A, Fig. 9, shows the lower jaw j open, and, as it is closed by means hereinafter described,

it confines the end of the wire, which lies across it and within the opening against the loop l, as indicated by the letter h. The wire thus held is fully shown at w, in Fig. 7 the upper end extending upward to the point of the binder-arm, as shown in the general view,

Fig. 3. The relative position of the wire 20', as thus held, with reference to the twister t and guard e will be more fully understood by looking at Fig. 6, which shows the wire w as being in aconvenient position to be swept by the hooks of the twister into the annular space between the stem of the twister and the inner concentric circumference of the guard 0 Now, as the gear G Fig. 6, is brought in contact with the pawl p and the twister is therebyturned one-half way around, as above described, the'wire w is caused to take the position opposite, as represented at w. This new position of the wire to is clearly shown in elevation in Fig. 7, in which posi-.

tion it is held until the point of the binderarm brings the wire around the gavel and down alongside of the twister, as shown at 20 Fig. 8. At this point the upper jaw j closes and gathers the said wire 'w in with the wire 10 over the center of the twister, as.

now being revolved by the gear G, as above described, the two wires w and 10 are sheared off at the under side of the twister at 1), Figs. 8 and 11, and the ends twisted firmly together below the point where the upper j aw j grasps the same.

It will be observed, by referring to Fig. 8,

that when the twister commences to revolve, and has madea half-revolution, the wires w and w will havecha'nged places-that is, the I former will occupy the position' represented by wl, drawn across the open lower jaw j and into the opening h of the same, as shown at w fin the sub-figure A, Fig. 9.After the wire 24: is severed at the cutting-point 'v, and before the binder-arm commences to 'rise, the lower jaw j will slide shut and seize the said wire nearits end, and, when the binder-arm rises, thewire @0 becomes inits turn the wire w, as originally described in Fig. 7. When the lower jaw closes on the wire, as just described, theiupper jaw opens and releasesthe sheaf just bound, which falls from themachine.

The upper jaw j, Figs. Z'and 10, ispivoted to and between the upper and lower sections of; the centering-plate 6 Fig. 9, at the point a, and the jaw-rod Z is jointed tothe'said jaw at a This arrangement of the jaw, together with the hooked form of the same, causes it to act favorably in bringing the wire held by the binder-arm 1.0 Fig. 8, into the center of the centering-plate and between the hooks of the twister.

The lever 12, Fig. 3,-connecting the ends of the jaw-rods, I design to operate substantially as in my patent above referred to. v

I form an offset in the binder-arm near its point, as shown in Fig. 8, the offset being away from the twister, so that therewill be space-back of the tightly-drawn wire w for the point ofthe jawj to reach in, in the act of gathering the said wire into the centering-plate, asabove described.

i It will be observed,.on reference to Figs. 1 and 8, that the offset in the binding-armdoes not extend entirely across the same, but that it islim'ited to the inside corner, and'that the outer edge or corner of the arm extends down in a straight line past the offset,-serving. as a guard to prevent the pressure .of the grain from forcing the wire back into-the offset out of the reach of the'twisting devices.

In Fig. 12 will be seen the spring-guard s fastened to a distant part of. the metal plate forming the guard c and reaching across the annular space to a point on or near the stem or shaft of the twister. As the wires press against the guard while being carried around by the twister, it springs out to the point of the guard e ,-thus closing the openingatwhieh the wires entered, andpreventingtheir escape.

The annular space between the guard-plate stand the shaft of the twister is sufficiently large to allowthe wire to move freely, and at the same time the guard-plate keeps the ends of the wire from spreading or turningouthorizontally while being carried around, as they are inclined to do. j

' The-wire for binding the grain is wound upon the reel E,,Figs. 1 and 3, and passes thencethrough the end of the guide-arm F,

which is provided with a roller, and point of the binder-arm, down to the'lower jaw j.

I is a cord-pulley, forming part of the reel around which the friction or tension cord K passes, which cord is drawn tight, having its endsfastened in the clamping-block M. One end of the cord K is made fast in the hole a of the said block, and the other, after being carried around the pulley and drawn to any degree of tension, is passed through the hole a under the clamp-screw 8 by which it is made fast. The friction between the pulley I and cord K' serves as a tension for the wire.

The guide bar or arm F, (best shown in Fig. 3,) is fastened to the bracket 9, and swings laterally with the same, which keeps the end of the wireguide at all times nearly over the point of the binder-arm. This relieves the cramping and friction of the wireas it is drawn through the opening in the point of the binder arm that attends the guiding of the same through a relatively-fixed gulde, as-heretofore practiced. w

The guidearm F is designed to be made stiff, so that it will not yield downward as the wire is drawn from the reel by the descent of the binding-arm; but the reel is purposely mounted upon a yielding spring-standard, 0 by which anyunusual ten sion upon the wire may be relieved. For instance,"when thereel is wound full, it is easily revolved by the wire drawing upon the outer circumference of the coil, and the tension of the wire is only maintained by the friction between the cord K and the pulley I; and when the reel is nearly exhausted the wire draws from a point near the axis of the same, in which case the friction upon I has the advantage of leverage, which would cause too much tension on the wire were it not that the spring-standard 0 yields forward in obedience to this tension, and relieves the friction on I above mentioned. By this arrangement the tension upon the bindingwire is equalized, and the same may be made greater or less by regulating the strain upon.

the cord K, as above described. g

0 Figs. 1, 2, and 3, is a compressing cord or cable, one end of which is detachably connected tothe compressor attachment O-fixed to the binder-arm, near its point. From the attachment 0 the said cord extends down to the twister-head H, over the roller d, and under the roller 0?, Figs. 1 and 2 and Fig.5,

thence back over the roller d, and downward around the tension or friction drum N, which is preferably attached to the driving-shaft J.

The said drum N is so constructed that it revolves with the shaft J, or in the opposite di rection wheu the upward movement of the binder arm draws upon the compressingcord 0?. v

The interior construction of the drum Nwill be understood from observing the enlarged sectional view, Fig. 13, Sheet 1. b is a circular metal disk, made fast to'the shaft J. The drum I) fits freely upon the :shaft at t, and its interior diameter is made slightly greater than the diameter of-the disk I)? Within the drumare confined several frictiondisks, 0 of leather, wood, rubber, or other suitable material, and by adjusting the pressure on the same by turning the jam-nuts f any desirable amount of tension or strain may be put upon the compressing-cord C The cord 0 is provided-with a ball or en- 1arge1nent,.g, at its end, which is lodged in the cavity h of the compressor attachment 0, as shown in the enlarged Fig. 15. The tortuous opening in the attachment 0 is of such a nature that the said ball is released only at a critical moment in the movement of the binder-arm, as will presently be explained.

Fig. 16,is a front elevation of the attachment 0, and Fig. 18 a cross-section upon the line 00 of Fig. 15, showing the ball g lodged in place. If we conceive the binder-arm with this attachment 0 as occupying the position shown in Fig. 1, and moving against the grain in the receptacle, as indicatedby the arrow 1 the compressor-cord C will be pressed back by the grain in a curved form, as shown. As the binder-arm moves on, the said cord will assume sharper. curves, and its-various positions with reference to the attachment 0 will be represented by the numerous dotted positions shown in Fig.16, 0 being its relative position when the binder-arm is at its lowest point and pulling downward on the same. The narrowness of the space 1 in the attach,- ment 0 back of the tongue 6, Fig. .18, prevents the ball g from being drawn through at any time, and the cord C is drawn around the tongue 6 at every position until it slips over the top'of the same, which occurs when near the position represented at 0 Figs. 15 and 16. Then the cord slips off the end of the tongue 45 it assumes the position represented atO but the ball isnot yet released, being temporarily caught in the concave ledge m,

Fig. 17, forming the upper wall of the cavity h. The ball is held in this position with the cord drawn tightly around the gavel during the period the binder-arm is at rest at its lowest point, as heretofore described. When the twisting has been effected and the binder-arm commences to rise, the tension on the cord ceases, and the ball thus released drops upon the lower inclined wall 4? of the cavity h, and escapes, releasing the bound sheaf. Just before the ball g escapes from the cavity h as above described, the cord 0 is again caught within the meshes of the attachment 0 at a point some distance away from the ball, preparatory to its becoming a compressor for the next gavel. It is accomplished as follows: Overlapping and outside of the tongue i is the thin, broad, and slightly-curved guard G pointing downward. WVhen the binder-arm moves downward through the twister-head H, the point of the same passes immediately back of that portion of the cord 0 that is drawn taut from the roller (1 across the-head .H, and around the gavel S, as shown in Fig. 19. As the said arm continues downward and reaches its lowest point the cord 0 is brought to the relative position shown at Fig. 20, inside of the guard G and some distance above the point of the tongue 1'. Now, as the arm rises the ball drops out, as above described, and the cordeasily-slips down back of the tongue 6, as will be readily understood by observing Fig. 20, and the position of the cord represented at 0 Fig. 15.

As soon as the ball is disengaged, relievingthe tension on the compressor-cord, the friction-drum N, Fig. 1, which had its motion re versed, unreeling; the cord while the binderarm encircles the gavel, and which was held relatively at restwhile the binder-arm rested, commences to turn with its shaft, and winds in the surplus compressor-cord in the direc.- tion shown by the arrow y Fig. 20. This brings the ball g back to the cavity h in the attachment 0, from which it had just escaped, as above described, the position of the compressor-cord and ballbecoming again as shown in Figs. 15, 16, and 18. This operation of the balland compressorcord is repeated with the binding and releasing of each successive sheaf.

The compressor attachment upon the binderarm, as shown in Figs. 1 and 3, is differently constructed from the one just described, being substantially the same inverted. It operates by releasing the ball in a manner similar, but contains no tongue 6, and catches the compressorcord in back of the guard G when it moves upward insteadof downward. As the binderarm moves downward into the twister-head H, the point of the same presses the cord into the hook i, which holds the same steady, and in a position convenient to pass in back of the guard G as the binder-arm rises, said guard pointing upward.

The grain, as it is brought up by the elevators, drops onto the receptacle B and under the strips D, Figs. 1 and3, the latter forming a wind guard, which prevents the grain from being blown off and scattered by the wind. The strips D are hung to the shaft U, which is mounted on projecting hangersfaste'ned'to the adjustable receptacle B, and located some distance above the elevator, said strips resting by their weight upon the grain as it lies in position toibe bound.

- The upper surface of the twister-head H stands abovethe surface of the horizontal portion of the receptacle B Figs. 1 and 3, upon which the sheaf while being boundis carried along over the said portion of the receptacle, comparatively free from and without dragging upon the same.

Fig. .tshows a front elevation on a reduced:

scale of a portion of the machine, showing the pickers or. feathering-fingers e? and e. They are pivoted upon the pins v and '0 respectively, of the revolving disks a and a", fitted upon the roller-shafts that carry the elevatorbelts B and are provided with slots that slide upon the studss. The lower arm serves to clearthe .point at which .it is located from straw that is inclined to lodge and tangle, and.

same Within the tire.

the tire may be tightened within a few min nected to the stud h, and by means of this arrangement the binding mechanism and weight P move in opposite directions when theformer 'is being shifted, keeping the aggregate weight of both substantially balanced upon the driving-wheel.

I do not desire to claim, broadly, in the present patent the automatic balancing of the machine as the binding mechanism is adjusted forward and backward, as means to that end .are provided in my patent of October 26,1875.

In that patent, however, provision was made more especially for shifting the drivers seat and reel or other part of the machine as a bali ance. The present invention is designed to overcome objections incident to the shifting of I said parts, and consists in the use of a counter-weight for the special purpose of balancing the binding mechanism.

In Fig. 2 the driving-wheel W is shown in section. The flange s and the hexagon-shaped hub a form one piece, and to the said flange s is fastened the gear G which turns with the driving-wheel. The flange s is provided "with a hexagon-shaped eye, which fits and may slide upon the hub ad, thetwo flanges being tied together by the tie-bolts j j &c.

The spokes of the driving-wheel being placed obliquely between the felly and the flanges, as the latter are brought toward each other with the tie-bolts the spokes will be forced out against the felly, tightening the By this arrangement utes at any time, and the labor upon the wheel is distributed equally upon both sets of spokes, and the gear G is not drawn sidewise or out of line with the pinion P, for the flange s is stationary, and only the flange 8 moves when;

the tie-bolts are drawn up.

Fig.21 shows the manner ofhanging the frame upon the driving-wheel W. Theview is taken in the same direction as that of the adjacent figure, 3, drawn to a reduced scale, with everything on the side of the driving- -wheel toward the observer remover I Q is a timber mating with Q ,lying beyond the driving-wheel, the position of which tim- *bers and driving-wheel between being shown in Fig. 1.

H H are hangers bolted to the opposing faces of the said timbers, each hanger being provided with a circular groove or slot, as -shown 'at K Fig. 21, made concentric with.

' the shaft D Within these slots,which stand facing each other, the ends of the shaft t that passes through thezhub a of the drivingwheel, rest. The shaft t does not revolve, the

hub of the driving-Wheel beingloosely fitted to turn upon the same.

Fig. 1, and the full lines of Fig. 21, show the frame dropped to its lowest position, the shaft t of the wheel W resting at the upper cndof the slots k By raising the frame as shown by dotted lines in Fig. 21, and securing the ends of the shaft in the slots k by some suitable fastening, the height of the cut of the sickle-bar maybe regulated at pleasure. The concentrieity of the slots k and the shaft 1) serve to keep the teeth of the gear G and pinion I in gear at all times.

The slack of the chain 0,Fig. 1,is designed to be taken up by adjusting the roller r up or down along-the slot 6 as shown.

By means of the clutch P, Fig. 2, the whole moving portion of the bindingmechanism may be thrown out of gear at pleasure. I also employ the clutch P, Fig. 3, on the pinionshaft J, by which the binding mechanism may be stopped at any time. This clutch is designed to be operated by the lever E Figs. 1 and 2, a connecting-rod from which is to extend to within reach of the driver.

It may be desirable to employ a long chain, as shown by the continuous heavy dotted line N todrive the rollers, &c., around which it passes, all directly from the drivingchain wheel W employing an idler, as shown at W located so as to keep the chain sufficiently around the wheel W.

The lever L, Fig. 3, may be so constructed as to operate directly upon the extended rear end of the binder-arm, as shown in the modi: fication, Fig. 22. y

As shown, the rear end of the lever L is ex.- -tended and bent upward, having a pin or roller, p projecting from its side near the end, which plays in the sinuous slot at of the binder-arm. The slot 61* must be so shaped that the traversing of the pin or roller 9 along the same, as the gear Gis revolved, Will give to the binderarm the desired motion. For instance, when the said gear revolves so as to carrythe pin 10 up to the point p in the dotted are, it will have reached the point I in the slot 01 and the binder-arm will be at its lowest position, as shown in dotted lines.

The remainder of the slot Z to I will occupy the position in dot- -ted lines from p to 19 which coincides with the dotted are centered at 0 and consequently there will be no vertical motion of the binderarm while the pin traverses the same. This gives the binder-arm the period of rest necessary, as above described.

The movement of an arm vertically and laterally around an axis by the direct action of a crank, I do not claim per se,bein g aware that a similar arrangement has been hitherto employed in connection with harvester-rakes.

Instead of the long pinion P, I may use a short pinion to drive the gear G, fitted to slide upon the shaft J, said shaft being provided with a spline of Sufficient length to accommodate the longitudinal movement of the pinion, which is provided-with a' groove or keyway, fitting the spline.

Flanges cast at the ends of the teeth of the pinion would prevent the gear moving away from it as the same was shifted.

A spoked wheel might be used instead of the slotted plategear G, the spokes being properly beveled, so the pin 4' of the bar a would slide up over them as the bar a moved back. Also, instead of the teeth on the gear G and pinion p, a chain might be mm on the periphery of the two, by which the pinion would be driven.

Having thus described my invention, what I claim isl. The combination of the binding-arm 'B and actuating-arm L, both extended in rear of their pivots, with a connecting-bar, It, attached to their rear ends, substantially as shown, whereby an unobstructed space is left for the grain underthe entire length of the binding-arm.
