Application tiled April 19,. 1395. Seria-l No. 546,337. (No model.)
T @ZZ wtont it may concern:
13e it known that l, WILLIAM S. SHAKEL, a citizen of the United States, residing at Metamora, in the county of Franklin and State of Indiana, have invented al new and useful Slioclf-llorming Attachment for Harvester-Binders, of which the following is a The purpose of the present invention is to equi p grain-binders with amechanism for au tomatically forming the sheaves or bunches into shocks and depositing the lattersquarely upon the ground.
A further purpose ot' the invention is to provide au attachment that can be readily applied to the various styles of harvester-binders and which will be compact in its structural arrangement and perform the desired work in an efficient and satisfactory manner and which in its organization will comprise a rotatable shock-termin g table upon which the sheaves or gavels are placed in an upright position, one ata time, until a sui'iicient number are in position to form a shock, when the latter is automatically grasped by arms, lifted l'rom the table, and carried to a point at the side ot' the machine and deposited on the ground.
lVith these and such other objects in view as belong to the nature et' the invention the latter consists of the novel features and the peculiar construction and combination of the parts, which hereinafter will be more fully described and claimed and which are shown Figure l is a perspective view of the shocktormiug attachment. Fig. 2 is an end view, looking from the front, having the carrier,
the limit of its outward movement. Fig. 3 is a top plan view of the carrier. Fig. @L is a side elevation of the carrier as seen from the remote side of Fig. i?. Fig. 5 is a bottom plan view of the invention, a portion of the cranlearm and the track being broken away. Fig. o is a section on the line X X of Fig. 5, looking in the direction of the arrow, showing the mechanism for actuating the shock-forming table. Fig. 7 is a detail View of the catches for supporting the gri pping-arms andl the means for releasing the same to permit the descent of the shock upon the ground.`
Fig. 8 is a section on the line Y Y of Fig. 2, looking in the direction of the arrow. Fig.
9 is a side elevation of a gripping-arm, showing its supporting-lieai'l in longitudinal section. Fig. 10 is a plan view showing the shock forming attachment applied to the frame of a low-down binder. Fig. 1l isa detail section on the line Z Z of Fig. 10 on a larger scale, some of the parts being broken away and others omitted.
The framework of the machine comprises a track l, having a post or standard 2 near its frontend, parallel bars S and et, au end bar 5, a cross-bar and a bar 7, secured to the end bar 5 and adapted to be pivotally connected at its side with the framework et' the harvester to which the attachment is to be applied. A clip 8, located at the inner end of the track 1, is designed to 'form pivotal connection between the track 1 and the said framework of the harvesting-maehine having the attachment applied thereto. Ashaft E) extends parallel with the bars 8 and 4 and is journaled near its ends in suitable bearings provided on the end bars connecting the extremities of the parallel bars and 4;. A sprocket-wheel 10 is mounted upon the end of the shaft 0 and receives motion 'from a convenient part of the harvester-actuating mechanism by means of a sprocket-chain 1.1. A bevel gear-Wheel 12 is mounted on the sha-f t 9,11aving the sprocket-wheel 1.0 in such a manner as to turn loosel57 on the said shaft, and is provided on one side with a halt-clutch 13, which is adapted to engage with a corresponding half-clutch let on the opposing end of a sleeve 15, having movement on the shaft 9 to and from the bevel gea.1.'wheel 12, so as to cause the halt-clutches 13 and le to gear and ungear according as it desired to cause the bevel gear-wheel 12 and shaft 9 to revolve together or admit of the shaft 9 revolving alone. This sleeve 15, while free to move on the shaft 9, is keyed thereto, so that the shaft and sleeve will revolve together. A spring 1G is disposed upon the shaft El and exerts a pressure whose normal tendency is to advance the sleeve toward the bevel gear-wheel 12 and bring the half- clutches 13 and 1+i int-o engagement. A cross-bar17 is eccentricallT journaled at its ends in the parallel bars 3 and 4, and its middle portion engages with an annular shoulder of the sleeve 15. A springarm 18 projects about at right angles from the cross-bar 17 and is engaged by a crank portion 19 of a rod 20, journaled in the bars 3 and 4, parallel with the cross-bar 17. The inner end of the rod 2O maybe of any shape, and, as shown, is bent at approximately right angles to form an arm 21, which is adapted to be engaged by the ejector ofV the harvesterbinder and move the rod 2O longitudinally when it is required to gear the bevel gearwheel 12 to the shaft 0. This arm 21 is not essential and may be dispensed with, and is provided only as a convenient means for the ejector to engage with. A bevel gear-wheel 22 is journaled to a bracket 23 on the bar 4f., and is in mesh with the bevel gear-wheel 12 and receives motion therefrom. Atrip 24 is provided on the side of the bevel gear-wheel 22, and is adapted to engage with the arm 18 and turn the cross-bar 17 in its bearings and move the sleeve 15, so as to throw the halfclutches 13 and 1l out of gear and permit the rotation of the shaft 9 without imparting a corresponding movement to the bevel gearwheel 12. A bundle-elevator 25 is j ournaled at one end in the bars 3 and et and is connected by means of a pitman 2G with the bevel gear-wheel 22, so that in the operation of the latter the said bundle-elevator will be raised and lowered to deposit thebundlcs or sheaves in a stan ding position upon the shock-forming platform or table 27. This bundle-elevator comprises a central support 2S and cross-arms 2), the latter curving or being slightly depressed betvveen their ends on the upper edges, so as to retain the bundles or sheaves in place when the bundle-elevator is depositing them in a standing position upon the shock-forming table 27. A sliding pawl 30 is connected by a link 3l to an arm 32 on the journaled end of the bundle-elevator 25 and is adapted to engage with a ratchet-wheel on the under side of the shock-forming table 27'. The parts are so disposed that when the bundle-elevator 25 is rising the pawl 30 is returning to a position to engage with a tooth of the ratchet-wheel 33, and when the bundle-elevator is lowering the pawl 30 is advancing and moving the ratchet-wheel a distance of one tooth, so as to bring an unobstructed portion of the shock-forming table opposite the bundle-elevator to receive the next sheaf to be deposited thereon.
The shock-forming table 27 is circular in outline and is rotatably mounted upon the cross-bar 6 and has a drop portion 34, which is attached to the body ot' the table by a hinge connection in any desi red mann er. The ratchet-wheel is secured centrally to the under side of the shock-forming table, and its teeth are spaced a su Ilicient distance apart to make room for a shea'f in the rotation of the table, so that after each sheaf or bundle has been deposited upon the table the latter will move forward the proper distance to bring an unobstructed portion in position to receive the next bundle. A detent-pawl S5 is pivoted at one end to the bar t and engages with the teeth of the ratchet-wheel 33 and prevents the table from turning back after it has been advanced by the action of the pawl SO. A supporting-ring 3G is placed upon the bars 3 and 4 and gives stability to the shockforming table. A segment of the ring, as 37, is adapted to drop at the proper time and permit the drop portion S-t of the shock-forming table to lower, so as to provide ample clearance-space for the depositing of the shock upon the ground. This drop-segment 37 is journaled .in the intercepted end of the ring 36, and one end portion is projected toward the track 1 and is bent to form a crank-arm 3S, which is engaged by a suitable portion of the carrier 39, so as to hold the part or segment S7 in a horizontal position until the carrier starts upon its sideward travel upon the track 1, when the said segment 37 lowers and permits the drop portion 31 of the shock forming table to lower, so as to prevent interference of the shock-forming table with the free dropping or depositing of the shock upon the ground. By providing the drop portion 34 the track 1 is enabled to be made shorter a distance corresponding to the width of the said drop portion 34. lt' this drop portion S-i were not provided, the track 1 would necessarily be longer in order to admit of the shock clearing its table when being deposited upon the ground. Y
On that end of the shaft i) contiguous to the track 1 is arranged a sprocket-wheel 40, having a half-clutch 41 on one side to engage with a corresponding half-clutch 42. on the Opposing end of a sleeve 43, mounted upon the shaft 9, so as to revolve therewith, but free to move to and jfrom the sprocket-wheel 40 to gear and un gear the half-clutches t1 and 42 to cause the sprocket-wheel 40 and the shaft 9 to revolve together when the shock is stifliciently formed to be deposited upon the ground. A sprin g atl is placed upon the shaft 9 and exerts a pressure on the sleeve 43, so as to bring the half-clutches 41 and yt2 into engagement when the said sleeve 43 is released from the restraining inuence of the bell-crank lever 115, which is pivoted at the elbow to a clip 46, having pivotal connection with the bar 4. By this mounting of the bellcrank lever -Lt the latter is adapted to have a twofold movement, the one on its pivotal connection with the clip 4:6 and the other with the clip 4G, so as to disengage its 'forwardlyextending arm from an annular shoulder on the sleeve 43. The end portion of the bellcrank lever -it extending parallel with the bar 4t projects within the path of a trip 47, attached to the shock-termin g table 27, to be engaged thereby when the shock-forming table has completed a revolution, so as to disengage the bell-crank lever 45 from the sleeve Li3 and admit of the half-clutches -tl and 42 coming into engagement, so as to cause the shaft 9 and the sprocket-wheel 40 to revolve IOO llO
as a unit. A spring 4S is mounted upon a cross-rod t9 and has one end in engagement with the frame of the attachment and :its other end constructed to press upwardly on the laterallyextending member of the bell-crank lever 45, so as to hold the other member in engagement with the sleeve t3 until released therefrom by means of the trip 47 in the manner just described.
A bearing 50 is journaled upon the inner ends of setserews 5l, which pass laterally through the bifurcated ends 52 ot a bar or rod 58, adjustably supported within the post or standard 2. A long crankdever 5l has its end portion 55 journaled in the bearing 50, and a sp1'ooketwliool56 is mounted upon the end portion 55 and receives a sprocket-chain 57, which passes around the sp rocket-wheel 40, so as to transmit motion 'from the latter to the sprocket-wheel 5G, by means of which the crank-lever 5l is actuated, so as to move the carrier 39 upon the track l.. A pitman 5S connects the opposite end of the crank-lever 5l with a crank-arm 59, which has its shaft portion G0 journaled in the side pieces ot the carrier Si), and which is adapted through suitable mechanism to operate the shock-gripping arms and cause them to embrace the shock. The outer end of the pitman 5S has a longitudinal slot 6l, which communicates with a lateral or branch slot G2, which slots unitedly form an Lshaped slot in which operates the connecting portion of the cranka-rin 59. A projection (i3 extends outwardly from the end ot the pitman 58 and is adapted to be engaged by a corresponding projection (ist of a lever G5, pivoted at one end to the side ot the carrier 239. A spring (3G is constructed to exert a downward pressure upon the lever G5, so as to hold its projection 64: out ot' engagement with the projection G3. A shaft G7 is journalcd in the side pieces of the carrier, and one bent end GS is connected by means ot' a link (S9 with the lever G5, and its opposite bent end projects within the pat-h ot one of the shock-gripping arms, so as to be engaged thereby when the shock is settling and cause an. upward movement of the lever G5 through the link G9 and bring the projection G4, in engagement with the projection (53 and litt the pitman 5S a su tticient distance to disengage the lateral slot G2 from operative engagement with the crank-arm 59, which latter will move in the longitudinal slot Gl and permit the shock-gripping arms to spring apart and release the shock.
The carrier 39 comprises side pieces 7l and 72, which are secured together and braced laterally in any convenient manner. rlhe lower ends of the side pieces are adapted to engage with and embrace the edge portions of the track l, so as to hold the carrier in place upon the said track. Rollers 73 are provided track l.
is thickened or provided wit-h a strip 74, which is engaged by the rollers 75 when the carrier starts upon its outward travel upon the track, so as to cause a slight tipping of the carrier from the perpendicular in a direction away from the shocleforming table, whereby the shock is slightly elevated from its`supportin gtable, so as not to drag thereon when moving thereover to be discharged at the side of the machine. A lever 75 is pivoted midway of its ends to the lower portion of the side 7l, and its ends are bent in opposite directions, the lower end having mounted thereon a roller 7G, which is adapted to engage with a stop 77, by means of which the carrier is held upon the track l directly opposite the shock-forming table 27, and its upper end is bent outward across the path ot' the crank-arm 59 to bc engaged by the latter at the proper time, so as to disen gage the roller 7 G from the stop 7 7 on the trackl to admit of the outward movement of the carrier on the track to deposit the shock upon the ground. A spring 79 is provided and serves to hold the roller 7G in engagemcnt with the stop 77 until its force is overcome by the movement of the crankarm 59.
Turn-posts 8O are disposed in vertical and parallel relation, and are journaled at their 'ends in laterally-extending portions ot the carrier-frame., These turn-posts are of such shape in crosssection as to form positive means of engagement with the inner end portions of the shock-gripping arms to cause the latter and the said posts to move in unison when the posts are turned upon their journals. For the sake of simplicity ot construction these posts are ai'lgular, and the inner end portions of the gripping-arms are of corresponding shape to iit thereon. A. lug Sl has pivotal connection with the lower end of each turn-post. A hub S2 is mounted upon the projecting end of the shaft GO, and its oppositely-extending arms S3 are connected 'by means of links Se with the said lugs Sl,
thereby formin g positive means of attachm ent between the shaft U0 and the turn-posts S0, wherebya movement of the said shaft GO will cause a simultaneous movement of the turnposts and an opening or closing of the shockgripping arms, according as the movement ot the shaft 130 is to the left or to the right. A coil-spring S5 is connected at one end to the frame of the carrier and at its opposite end to the part 83, and exerts a pressure so as to hold the shock-gripping arms separated during the formation ot' the shock.
The shock-gripping arms 86 are of similar construction, and are formed from heavy wire or thin rod-steel and have their outer' portions oppositely curved, so that when brought together they will form an approximately circular inclosu're, and have their shank portions secured to heads S7, which latter are castings and have openings SS to receive the turn-posts SO. Rollers S9 are disposed at diagonally opposite points within the openings IOO IIO
S3, so as to prevent binding of the heads 87 uponthe turn-posts in the movements of the said heads S7 upon the turn-posts 80. The heads S7 are adapted to move vertically upon the turn-posts S0, and have a yielding connection with a cross-bar 90, secured at its ends in the vertical portions of a bar 91, pivoted midway of its ends to the top of the carrier-frame 39. A double spring 92 is mounted upon the cross-bar 90, and its outer end portions are bent to engage with the pivoted bar 91, while the middle portion forms an outwardly-extending arm 93, which is connected by means of a short chain 94 with a spring-coupling 95, and the latter being connected in turn with the said heads S7 by means of short chains 90. The spring-coupling 95 may bc of any suitable construction to admit of the lengthening and shortening of the chains 94 and 90 when the arms 80 are lowering toldeposit the shock upon the ground. The arm 93 will also yield so as to admit of the lowering of the shock, as will be readily understood. A roller 97 is provided on the cross-bar 90 and relieves friction on the chain 94 in the movement of the latter over the said cross-bar 90.
The shockLgripping arms 80 are supported at their highest position upon the turn-posts S0 by means of catches 98, which normally project across the path of the inner ends of the heads S7, so as to come beneath the latter and prevent a descent of the gripping-arms until the carrier reaches the outer end of the track 1. A rod 99 is connected at its upper end with a crank portion of the catches 98, and its lower end is adapted to be engaged by a stop 100 at the outer end of the track 1 for the purpose of withdrawing the catches 9S from beneath the heads 87 when the carrier 39 reaches the end of the track 1, thereby per mitting the shock-gripping arms S6 to descend under the weight of the shock embraced thereby.
A star-wheel 101 is journaled on the outer end of an arm 102, and normally occupies a position directly over the center of the shockforming table 27, and is designed to retain the sheaves or bundles in place during the formation of the shock. This arm 102 is slightly elastic to permit a yielding of the star-wheel from its normal position when subjected to abnormal strain, and its inner end 103 is curved and operates through a guide 104, secured in a head S7. A spring 105 is mounted upon the curved end 103 of the arm and holds the star-wheel in proper position. A slide 106 is mounted upon the head 87, carrying the guide 104, and is held in the located position by a binding-screw 107, which passes through the slide 10G and is adapted to bear against the head 87. The arm 102 is pivotally mounted upon the slide 10G, and by moving the latter the tension of the spring 105 can be adjusted so as to cause the star-wheel 101 to sustain a greater or less pressure. In order to insure the passage of the sheaves between the ends of the shock-gripping arms 8G, the extremities of each or both are bent outward toward the bundle-elevator 25, as shown at 10S.
As previously intimated, the attachment is designed to be secured to the framework of a harvester-binder of any desired make by pivotal connections, so that when the machine is not required for use the attachment can be folded into -a compact form. vThe attachment must be so disposed that the sheafor bundle after being bound is deposited upon the bundle-elevator 25 at the same time the ejector of the harvester engages with the bent end 21 of the rod 20 to move the latter and release the sleeve 15, which, under the action of the spring 16, brings the half-clutches 13 and 14 into engagement and causes the bevel gear-wheel 12 and the shaft 9 to revolve together, and by means of the mechanism hereinbefore set forth the bundle-elevator 25 is raised to a vertical position and deposits the bundle or sheaf upon the shock-forming table. During this interval-the pawl 30 is returning to engage with the next tooth of the ratchet-wheel 33, so that as the bundle-elevator lowers the pawl will engage with the ratchet-wheel and move the latter so as to advance the shock-forming table a distance corresponding to the space occupied by the sheaf or bundle just placed in position and bring an unobstructed portion opposite the bundle-elevator to receive the next sheaf. This operation is repeated until the shock-forming table is filled and has made a complete revolution, when the trip 47 will engage with the projecting end of the bell-crank lever 45 and disengage the latter from the sleeve 43, when -the latter will move under the action of the spring 44, so as to bring thehalf- clutches 41 and 42 in engagement and cause the sprocket- Wheel 40 and shaft 9 to revolve together and cause a rotation of the sprocket-wheel 5G by means of the sprocketchain 57 in the manner described. As the sprocket-wheel 56 begins to turn the crank-lever 54 will operate and move the crank-arm 59, and through the mechanism herein specified will cause the shock-gripping arms S6 to embrace the sides of the shock and grip the latter in a firm embrace. As the crank-arm 59 reaches the limit of its throwit will engage with the upper bent end of the lever 75 and disengage its lower end from the stop 77, thereby releasing thc carrier, which will begin its movement upon the track 1. WVhen the carrier begins its outward movement on the track, the rollers 73 will engage with the thickened or stripped portion 74 of the track and cause a canting of the carrier sufficient to lift the shock from its supporting-table to prevent the dragging of the shock thereover, and at the same instant a hook or stop 109, provided on the carrier, will be withdrawn from engagement with the crank-arm 33 of the segment-drop 37 and permit the latter and the portion 34 of the shock-forming table to fall to an approxi.- mately vertical position. As the carrier IIO reaches the limit of its rearward movement upon the traek 1 the rod 9D will be engaged by the stop 100, and the catches 9S will be disengaged from the heads 87 of the shookgripping arms, thereby permitting the latter to deseend under the weight of the shook earried thereby. At or about the instant the shook reaehes the ground one of the heads 37 will engage with the bent end 70 of the shaft (i7, and through the eonneetions herein referred to will eause an upward movement of the rear end of the pitman 5S, thereby releasing the Crank-arm 59 from the lateral slot 62, whereby the said eranloarm 59 is free to move in the longitudinal slot G1 and will permit the shoelogripping arms SG to separate under the compression ot' the shook, so as to release the latter, whieh will drop upon the ground. The double spring 92 and the spring-Coupling 95 will regain themselves and bring the shookgripping arms back into a normal position upon the turn-posts 80. T he sprocket-wheel 513 eontinuin g 4to revolve will, through the aetion of the crank-lever 5l and pitman 5S, return the carrier 3f) to a normal position upon the traek, and the hook or stop 109, engaging with the crank-arm 3S, will return the drop portion of the shook-forming table to a normal position, and at the same time will engage with the bell-Crank lever l5 and throw the sprocket-wheel out of gear, thereby bringing the parts into a normal position for repeating the operation just described.
It must be understood that the shaft 9 is Continuously rotated and that the operating' parts driven therefrom are thrown into gear at the proper time to attain the desired result.
In providing and adapting the attachment for the various makes of harvester-binders on the market and in use it is obvious that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prineiple or sacrificing any of the' advantages of this invention.
The eatehes 9S are integrally formed from a single length of wire which has its end portions bent about at right angles and again outward to form journals 110, by means of which the eatehes are journaled in suitable bearings provided on the carrier-frame. One extremity of the wire is bent outward to form a crank-arm 111, wheh has attael'iment with the rod 9S). A. spring 112 has its upper end constructed to engage with the carrier-frame and its lower end attaehed to or -forming a part of the eatehes, so as to hold the latter projected aeross the path of the inner ends of the heads S7 to eome beneath the latter and support the ShOCkgripping arms in an elevated position. This spring 112 is preferablyformed as an integral part of the wire from which the eatehes are formed.
W hen the bundles are being deposited upon the shook-'forming table, the gripping-arms stand apart, and in order to prevent the possibility of abnndle eenling between the shank portions of the said arms a eonneetion or chain 113 is attached at its ends to the respective shank portions of the arms and entends aeross the spaee oeeurring between them and forms praetieallya continuation of the curved portion of the said arms. This is indicated most Clearly in Fig. 3.
After the crank-arm 59 has been actuated to cause the arms 8G to grip the shook and immediately before the carrier 39 starts on its outward journey a shoulder or stop 114 of the lever engages with a eorresponding shoulder 115 of the crank-arm 50 and looks the latter against any possible movement whieh would have a tendency to loosen the grip of the arms S6 upon the shook until the said lever G5 is aetuated in the manner set forth, so as to simultaneously release the Crank-arm 59 from the lever (35 and the pitmau 5S.
The rod 20 may have any required shape at its inner end so as to be engaged by an ejeetor of the harvester, by means of which it reeeives a longitudinal movementiin the supporting-bars 3 and Ll, so as to force the springarm 1S out of the path of the trip 2i, thereby permitting the eluteh-seetions 13 and 14, to engage and eause a rotation of the gearwheel 22, by means of which the bundle-earrier is operated. The spring-arm 1S, regaining itself, returns the rod 2O into a normal position, so as to be engaged by the ejeetor when the latter throws a bundle from the harvester upon the bundle-earrier.
In the formation oi' the shoe-k the bundles will erowd the arm 102 to one side in. an opposite direction tothe movement of the shookforming table, thereby making provision for the formation of the shook in the manner set forth.
The spring S5, in addition to its ordinary function of normally holding the grippingarins SG separated, serves, when the crankarm 5) is released, to cause the gripping-arms Se to separate quickly, so as to permit the instant release of the shook. The spring 4S serves to hold the end of the lever L15 within the path of the trip 4:7 on the shook-forming table, so that the said lever 45 will be engaged by the trip 17, whereby the desired result is effect-ed.
lvhen the carrier 3D is at the inner end of the traek, or in a normal position, the stop 109 will be in engagement with the end of the lever 45 and hold the same against the tension of the spring 4t, so as to maintain the clutch-sections y-11 and l2 out of engagement, and when the table has made a revolution the trip 4:7 will engage with the lever t5 and turn the same, with the elip to', so as to disengage the ends of the said lever l5 from the stop 109 and the sleeve 43, when the spring at, being released, will regain itself an d cause the parts of the eluteh to engage. The eranklever 54 oeeupies an approximately vertical position when the Carrier 3S) is in a normal position and the slot (32 of the pitman. 5S is IOO IIO
A(s v 559,819
in engagement with the crank-arm 59, so that the moment the clutch-sections 4l and 42 come into engagement the crank-arm 59 will move and effect a gripping of the shock, after which the carrier 39 will begin its outward movement in the manner set forth. A stop l l G limits the outward m ovem ent of the crankarm 59 and sustains the thrust of the pitman 5S. After the shock has been deposited the carrier will move inward to its normal position by t-he continued rotation of the cranklever 54, the mechanisms being so timed that when the carrier reaches its normal position the stop 109 will have engaged withthe lever 4:5 and disconnected the clutch- sections 41 and 42, and the roller 7G of the lever 75 will have engaged with the stop 77, thereby securing the carrier in its normal position until released in the manner set forth. As soon as the crank-arm is released in the manner set forth it will move backward in the slot G1, and as the pitman makes its return stroke the said crank-arm 59 will be drawn against a stop 11.7 and move the carrier 39 to a normal position. The parts 5,4, 58, and 59 are so proportioned and related that the cranklever 5et makes a complete revolution during an outward and a return movement of the carrier. Under normal conditions the springarm 1S extends within the path of the trip 2i and is engaged by the latter so as to hold the parts 13 and 1st out of engagement. The gearwheel 22,being operatively connected with the sliding pawl 30, which is held in locked relation by means of the ratchet-wheel 33 and the detent 35, will be prevented from turning under the influence of the spring 1G when the clutch-sections 13 and 1i are separated, as will be readily understood.
The attachment is shown applied to a harvester-binder of the low-down type, and inl which 118 is the -framework, 119 the carrier, 120 the 4drive-wheel, 121 the binder-arm or needle, 122 the packer, 123 the ejector, and 124 the actuating mechanism for the operating parts. As the ejector rotates it discharges the bundles from the gavel-compartment 125 one at a time upon the bundle-carrier 25, and the advancing curved edges of the ejectorarms coming in contact with the inner end of the rod 2O or its bent end 21 move the said rod 2O and start the shock-forming mechanism, as herein fully explained.
