BINDING ATTACHMENT FOR REAPERS AND HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 227,774, dated May 18, 1880.

Application filed October 10, 1879.

To all whom it may concern Be it known that I, JOSIAH D. HEEBNER,'of Nortonville, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Binding Attachments forReapers and Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the drawings, Figure 1 is a side elevation of my improved binding attachment. Fig. 2 is a top-plan View of same. Figs. 3, 4, 5, 6,- 7, and 8 are detail views of the case and its contained mechanism. Figs. 9, 10, and 11 are detail views of the curved upright standard and its attached parts. Fig. 12 is a detail View of cutter, showing arm in cross-section.

Operators of grain-binders as heretofore andj at present constructed have experienced considerable trouble by their machines becoming 2 5 inoperative through the derangement or breakage of the various parts, and especially of the parts included in and composing the tying mechanism. This is owing in a greatmeasure to the complication of parts in said tying o mechanism, which complication of parts I have in the present invention sought to avoid, my object being to provide a binder attachment in which the parts, and especially those parts composing the tying mechanism, should 3 5 be simple, durable, and compact; and to this end it consists in the arrangement of the parts comprising the tying mechanism, and in the means of operating the same, substantially as hereinafter set forth and described.

Referring to the drawings, A represents the platform or table of a harvester, reaper, or grain-binder.

B is the binding-arm, secured in any suitable manner-as, for instance, by a key or set- 5 screwto a shaft, 1), which shaft has its bearin g at b b in two upright standards, 0, upon the platform or table A.

The shaft 1) is rotated by means of a sprocket-whee], b (on the shaft 22) and a chain, said chain connecting it with a similar sprocketwith.

wheel on the main driving-shaft of the harvester or reaper. 1

The platform A is providedwith a slot to allow thebinding-arm to pass under the grain upon said platform when the machine isl'o'e- 5 5 ing operated.

Secured to the platform or table is an up a right curved standard, D, the said standard being hollow and containing certain mechanism for operating the tying mechanism, as hereinafter described.

E is the spool for holding the cord, and is mounted in standards 0 6, attached to the upper side of the platform. (Shown in Figs. 1 and 2 of the drawings.)

The outer or free end of the bindingarm terminates in a slotted or grooved box or case,

F, for holding the tying mechanism. The case or box F has one side inclined or cut away from a point, f, near the middle of one side to the opposite outer corner, thus terminating in a point, f, as shown in the drawings, by reason of which inclined surface the cord is more surely directed to and into the slot f in said case, and also the case itself will more easily penetratethe straw. V

The case F is made in three parts, F F F the central part, F forming a continuation of the binding-arm, being cast or forged'there- The upper and lower parts, F F are secured to the central part by screws or bolts, as shown.

The central part, F is made somewhat narrower than either the upper or lower parts, F F, the shorter sides of each of the latter being rabbeted at f 3 f asshown in detail,.thus forming, when the parts are in position as a whole, a groove, F, the object of which groove is hereinafter described.

Extending from the forward inclined part of 0 the case, and in a parallel line with the side a of said case, is a slot, f which slot catches and directs the cord to the tying mechanism contained in F. Theupper rear portion of F is recessed at a to receive an annular toothed 5 disk or ring, a which disk or ring fits accurately within said recess, just enough space being allowed for the ring to rotate freely without binding.

The recess a is provided with an opening to ,1 oo

the groove F through which the teeth of the disk extend into said groove in order that the disk may be rotated at the proper time, as hereinafter described.

One of the spaces between the teeth is extended inward nearly to the internal side or edge of the disk, forming a slot, a, which slot, when the disk is at rest, is directly in line with the slot f in F, and receives the cord entering the latter. At the lower edge of the internal side or edge of the disk is a flange, a its object being to further strengthen the disk. Directly beneath the disk a and forming a portion of the bed upon which said disk rests, is a latch or. griper, c. The rear end of the latch is elongated and is pivoted to the rear screw or bolt, 0, in a recess provided in the under side of F and about said screw or bolt for that purpose. When the latch or griper is in place its under side is flush with the bottom of F A slot, 0 in the latch allows the tying-finger to be operated, as hereinafter described.

The griping-jaw c of the latch 0, when the tying mechanism is being operated, impinges against a counter griping-jaw, 0 attached to the lower section, F of the case F. The latch or griper and the griping-jaw in F are made of steel tempered to resist wear.

The griping-surfaces may be corrugated, or the jaw may have a groove, into which the jaw 0 may fit, each of which modes of construction being to increase the friction of the cord between the jaws, thereby preventing said cord from withdrawing ere released by the gripers.

When the tying mechanism is at rest the jaws c c are held apart by a spring, 0, that throws outward the latch. In the upper surfaces of the griping-latch c and section F is a second annular groove or recess, (4., its purpose being to allow passage-way for the cord during the tying operation. The lower part, F is provided with a circular opening, e,directly beneath and corresponding in size with the central opening in the disk a in'which openingis fitted a plug or mandrel, 0 which plug will move freely in the opening 6, and is held in position therein by two leaf-sprii'igs, e c, resting and secured in grooves c c in the upper side of F".

The springs a may be attached to F in any suitable manner. Upon the outer or free ends of the spring are spurs 0 which spurs project into small slots 0 in the sides of the plug, thus retaining it in place. Upon the outer end of the plug is an inclined or wedge-shaped projection, (I, which projection serves at the proper time to press the plug inward. When it is so acted upon two small spurs, d 01, upon the upper inner end are pressed against the disk 09, thus preventing the cord from becoming entangled and holding it in position for tying the knot.

The inner end of the plug has a circular groove cut therein to allow passage-room for the tying-finger, said groove being cut from side to side and passing upward between the spurs d d. The plug is prevented from r'otating by a spur, at", which extends into a groove, (1 in F Aslot, dflin theforward part of the plug, and in line with the slotf in the case, allows the cord to enter the slot to in the disk.

Directly above the disk at and in the under side of the section F is cut a circular groove, (1 to allow room for the passage of the cord above the disk. A slot, cl, is cut through the part F, in which slot is placed a small mutilated gear wheel or pinion, d pivoted to lugs d d upon the under side of F. The lugs extend through the opening in the disk (0 and are flush with the bottom of the same. The

teeth upon the pinion d extend upward through the slot d and engage with the teeth of a rack, g, formed upon a sliding block, G, that slides to and fro in a dovetail slot or groove, 9, on the top of F, for a purpose hereinafter described.

The outer side of the block G is provided with two wedge-shaped projections, h h, by which projections the block is slid to and fro.

One of the teeth upon the pinion is elongated and forms a finger, the edges of which are slightly rounded,so that the cord may not be cut or injured by said finger when tying the knot. The space between the finger and the next following tooth is deeper than the baseline of the regular teeth, andhas its sides and edges rounded for the same purpose as those of the finger were.

At one side of the lugs al is a projecting spur or anvil, d against the top of which the cord is pressed at one stage of the process of forming the knot. The outer edge of the anvil is slightly rounded to allow the internal.

side or edge of the disk, against which edge it is pressed, to move freely. A groove, 61", at the base of the anvil allows the flange a of the disk passage-room.

The operation of the above combination is hereinafter fully set forth and described.

The arm or standardD is curved in a segment of a circle the radius of which is the radius of the are described by the binding-arm. The arm consists of a back, 9 and side g cast entire, the opposite side, 9 being cut away, as shown, in which opening is placed a spring, H, secured to D at h, for the purpose of holding the binding-head F against the side 9 Upon the side g is secured a circular rack, g, the depth or thickness of which rack corresponds with the width of the groove F in the binding-head. The teeth upon the rack, when the binding-arm is rotated, engage with the teeth on the disk a thus rotating the latter, the disk turning twice in the length of the rack.

Beyond the rack, on side 9 and at the upper free end thereof, is a slot, 9 to allow the sliding block G passage-way at a certain stage of the tying operation.

Attached to the inner side of the back g of D is a strip, 7L2, the front edge of which forms a cam-track, against which one of the projections h on G slides, for the-purposeof placing the finger g in the proper position for taking the cord. The front edge of the strip h is parallel to the side of the arm D. The lower half of the strip is somewhat narrower than the upper, the point of junction being slightly inclined, to allow the projectionh to easily pass from the lower to the upper track. The lower end terminates in an inclined plane, so that the projection h may readily pass to the cam-track.

Directly opposite the upper end of therack g", and secured to the back of D, is a second cam-strip, it the front edge of whieh is inclined forward from the side of the arm D, and terminates near the center of the arm. The projection h of G strikes against and is moved by M, which movement rotates the pinion d and completes the knot, as hereinafter described. A spring, h, serves to prevent the cam-track on [L3 from becoming inoperative through wear.

The arm D is partially covered on its inner side by a face-plate, I, which is secured by screws to the side g a passage-way being left between the plate land the side 9?, through which the binding-arm travels.

Upon the inner side of I, and at the free edge thereof, is a cam-strip, '5 against which strip the projection cl on the plug 0 slides, and by which the plug is forced against the disk At the lower end of the arm D is a square opening, 73 out through the back 9 Upon the inner face of the back, and partially sur rounding said opening, is a projecting block, i the upper edge of which, i has a square sharp edge, the opposite edgea', bein grounded.

Directly in line with the opening i and passing through a suitable guide in the frame supporting D, is a rod, F. The rod i is provided at its inner end with an oblong cutting and pinching head, i At one side the-head projects about half its length beyond the side of the rod, as shown at 41 The upper side of the head has its lower edge sharpened to cut the cord, while the edges of the lower side are slightly rounded to hold the cord.

Directly opposite the cutting and pinching head i and upon the inner'side of the face I, is asliding finger, L, which finger moves backward and forward in a dovetail groove, 1, in-the face-plate. The finger extends from side to side of the arm D, its outer end having' a slot, l, in which the end of a leaf-spring, l fits. A spur, Z is attached to the inside of the spring, and extends through the side of D to the inside of the arm, the object of the spur being to press the spring outward when the ease F strikes said spur, and thus move the finger L from the track of the arm B. The purpose of the finger L is to hold the cord down and in position to be grasped by the pinching-head 2'.

The outer side of the head is from its center beveled downward to its projecting edge,

'from'a cam, L upon one end of the shaft 1) of the binding-arm. The cam is circular in general form, having at one side a slight hollow or depression, k closing the cam 70, is a yoke, 70. From the forward inner side of .the yoke extend lugs 70 70 between which lugs is mounted a small roller, 7a, which runs upon the surface of the cam. In practice, however, the roller maybe omitted and a spur used instead. A spring, it placed between the frame and lever K, serves to keep the roller firmly against the edge of the cam.

The operation of my improved binder is as follows: The sheaf of grain is in position to be bound, and one end of the cord is secured in the griper i at the lower part of the arm D.- The binding-arm now rotating strikes the cord near the spool or reel. The cord, catching upon the inclined part of F, slides down said incline and enters the slots in the case F, disk a and plugc respectively.

The binding-arm B passes onward, the case F carrying the cord about the grain and into the Upon the pitman, and in lower end of the arm D, where the cord at-..

tached to said end is again secured by the incline and passed into the slots, as before, the sheaf of grain being inclosed by the loop thus formed. Tension may be given the cord in any suitable manner not described herein. At this moment one of the spurs h on the block Gr strikes against the inclined lower end of the cam-strip If, and thence moves to the face of same, thereby moving the block G, and thereby rotating the pinion d and setting the hollowed space between the finger g and the next following tooth in position to receive the cord entering the annular recess a. At the same time the wedge-shaped projection d on plug 0 slides under the cam-strip i on face-plate I, moving the plug 6 inward and holding the spurs d d firmly against the disk (0 The case F now passes onward a short distance,-

the rack entering the groove F, the teeth of said rack engaging in the teeth of the disk a moving it slightly. The edge of the rack now presses against the latch a, pressing it inward against the two strands of cord, holding the same tightly against the jaw 0 At this moment the projection or roller k in the yoke of the pitman k drops into the depression 70 of the cam 76 The spring is" forces the outer arm of the lever outward, thereby moving the rod i into the arm. The cutting and griping projection on the head now releases the end of the cord, and at; the same time catches the i cord below F and draws it into its bed, cutting off the part carried by F and holding the end leading to the spool. The disk 66 now respace in the pinion d volves, carrying the ends of the cords into the respective recesses above and below the disk a, the lower strands being carried into the When the disk a has made a half-revolution the spur 71/ passes to the wider part of the cam-strip 7L2, moving the block G, and thereby causing the finger to be pressed downward against the top of the disk a which disk now makes from this point one full revolution, carrying the cord around the spurs d d of the plug 0 and above the finger g. It will be observed that the cord will now be above or across the cord contained in the space between the finger and teeth. The projection h now strikes the edge of the cam It, moving the block G to the opposite side of F and into the slot 9 thereby revolving the pinion (l and pressing the finger g down upon the top of the anvil d", the second strand of cord being held firmly between the finger and anvil, and forming a loop for the knot. The rack g new releases the disk a and also the latch 0, and the spur h clears the cam-strip h, after which a slight incline in the forward end of the slot 9 moves the block G backward, releasing the finger g and allowing the completed knot to be drawn from the case F. The bound gavel is now discharged from the machine.

Having thus described my invention, What 1 claim as new, and desire to secure by Letters Patent, is-- 1. In a grain-binding attachment, the con1 bination of the case F, having groove F and slot f with an annular disk, a recesses a and d plug 0 having spurs cl (1 and projection d, springs 6 e groove 0, gripplelatch a, pinion (1 having finger g upon its lower side, anvil d block G, having rack g and projection h h, and movim in dovetail wa all arranged in the manner and for the purpose substantially as herein set forth and described.

2. In a grain-binding attachment, the upright curved arm D, provided with the spring. H, curved rack 1 cam-tracks h h slot g, opening 11 and block 4), having cutting-edge i and griping-edge 2"", in combination with a suitable rotating binding-arm and tying device, substantially as and for the purpose set forth.

3. In a grain-binding attachment, the combination of the cam k on shaft b, pitman 7c, yoke k roller It, lever K, spring 70 rod having cuttinghead i, with the cutting-block i and arm D, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of October, 1879.
