This invention,which is an improvement on a patent granted to me on the 30th day October, 1883, and numbered 287,695, appertains to the class of self-binding harvesters, the improvements relating particularly to the compressing, ejecting, and cord holding, knotting, and cutting devices, and the mechanism which actuates said devices.

The invention consists in the construction and arrangement of the various parts, hereinpointed out in the appended claims.

'anism will then be described in their For convenience and clearness, the main frame, the attached binder and compressor arms, ejector-rake, and mechanism actuating said arms and rake will be first described. The compressor mechanism and binding mechproper order.

In the accompanying drawings,A represents the bed-frame of the machine, of which a is the receiving and a the delivering end.

A is the platform, along which the bundles are discharged, extending from the end a to the end a.

A is a standard, rising from the rear part of the platform at the end a, and having. the

compressor and binder arms pivoted oppositely upon it on its outer and inner sides, respectively, as shown.

a" is a curved cord-directing arm secured to the top of the standard and carrying the spoolbox a on its rearward extension behind the standard. The front end of the arm is bent downward and inward, and is provided with an aperture, through which the cord runs to the binder-arm.

a is a spring-plate secured to the side of the Q arm a as shown.

a is a bifurcated lug upon the main frame in rear of the standard A.

a is a sprocket-wheel actuating all parts of the machine and driven by a chain from a like wheel secured to-the axle or one of the main wheels. The sprocket-wheel a is journaled on the main frame at the end a, and its shaft carries the crank-arm a, provided with a vertical friction-roller, a

B is a longitudinally-slotted lever pivoted upon the main frame at the end a, and having at its front end an S-shaped extension, 6. The friction-roller a enters the slot of the lever, travels in the-same, and vibrates the lever when the sprocket-wheel rotates.

b is an extension from the rear end of the lever B, provided with avertical pin, b*, at its end.

B is a lever pivoted at the end a of the main frame outside the lever B, and provided at its rear end with the slotted enlargement b into the slot of which the pin 1) enters and vibrates the lever B oppositely to the lever B. The lever B actuates the compressor and binder arms and binding mechanism, and thelever B actuates the ej ector-rake.

the long longitudinal guide-slot c, and at thev outer end of said slot with the vertical lugs c and c, respectively,upon its upper and lower edges.

c is a guide-loop on the rearward surface of the bar 0 outside said lugs, and c is a flat spring secured to the edge of said bar above the loop 0.

D is a reciprocating bar traveling on the rear surface of the bar 0, and supported by the loop 0 and slot 0, its inner end being provided with a square lug, d, which enters said slot and is retained therein by a washer and pin, as shown. The bar. D has on its lower edge the rectangular notches d d, the former near its inner and the latter toward its outer end, and upon its upper edge is the rectangular notch d, situated between the former notches, but near the notch d.

d is a laterally-swinging link-bar pivoted to the inner end of the bar D and to the end of an arm, 11", which extends outward from the bend of the lever B, so that the vibration of said lever causes the bar D to reciprocate.

E is the curved binder-arm pivoted near the top of the standard A, and having its rearward extension, E, connected by a link, e, to the inner arm of a bifurcated vibrating lever, e, pivoted upon the bracket a e is a link-bar pivoted to the outer arm of the bifurcated lever and to the lower end of a vibratory arm, e, having its upper end pivoted on the lug c.

F is a compressor-arm pivoted on the standard A oppositely to the binder-arm, and provided with the rearward extension, F, which until its return to the outer side of the notch is connected by the link f to the inner arm of the vibratory bifurcated lever f.

f is a link-bar pivoted to the arm of said lever and to the upper arm of avibratory bar, f, pivoted at its center upon the lug 0 The lever f is pivoted in the bracket a ,inside the lever e. When the bar D is at its limit of motion inwardly, the arm 6' and the downwardly-bent end of thelinkbar e rests upon its upper edge outside the notch d, the lower end of the arm inclininginward. The link-bar c then holds the lever e'inclined, soasto draw down the upper end of the link e and the extension E' and hold up the point of the binderarm. As the bar D moves outward the bent .end of the bar e and arm as fall into the notch d, and in riding out of the same the arm e is inclined outward, drawing back the link-bar,

so as to cause the lever e to assume an erect position. The end of the binder-arm then falls. As the inclination of the arm 6 cannot reverse by the inward reciprocation of the bar D, the

binder arm must remain down all the time that the arm 6 is inside the notch and up all the time that it is outside the same; but as the said notch is only a slight distance inward from the said arm when the bar D is at its inward limit of motion, the hinder-arm will fall when the said limit is nearly reached, and will rise again just after the beginning of the return of the bar D. The upper edge of the bar on either side of said notch consequently gives the proper pauses to the binder-arm, and their comparative duration is effected by the position of the notch. When the bar D is at its limit of inward motion, the upper end of the barf and the upwardly-bent end of the linkbar f are' in the notch d with the bar f", inclining thence downward and outward, and its lower arm against a proper stop on the lug a. The link-barf then inclines the lever f, and by means, of the link f keeps the compressor-arm raised. As the notch travels with the outward movement of the bar D the inclination of the barf is reversed, the link-bar f drawn outward, andthe compressor-arm F falls. It remains down until the ends of the barf and link f have entered and are passing out of the notch d, when a depending lug, Z, attached to the bar D, inside said notch, strikes the lower arm of the bar f, causing its upper arm to engage-against the outer wall of the notch and reverse itsincliuation and raise thereby the compressor-arm, which remains up till the bar f is reversed in inclination by the notch d", as before. The compressor-arm is thus raised and lowered at each inward and outward motion of the bar D, being lowered slightly before the binding-arm to compress the gavel for the latter. The lower or outer part of the compressor-arm is recessed from its outer edge, and has pivoted within the recess F the barf, recessed longitudinally from its inner edge.

f is a bar lying in the recess of the arm, and having its upper end pivoted in the recess of the bar f The bar f is longitudinally slotted, a pin, f, passing through the slot and through the walls of the recess of the compressor-arm. When the compressor arm falls and strikes the bed plate, the barf is driven upward and throws outward the recessed bar f, driving all loose straw from the gavel that might interfere with the cord on the binderarm.

f" is the compressor-cord, fastened to the compressor-arm at f", thence passing through the opening f of the same, and thence through an opening in the outer end of the spring f.v

secured to the standard A before descending to the compressor mechanism, hereinafter described.

G is the ejector-rake, having its handle or IIO arm extended outward beyond the pivot, and having its inner edge concave, so as to lie and bind on the convex edge of the arm y when the rake is lifted.

g* is a link pivoted to the upper end of the link 9 and to an upward extension, g, of the slide.

9 is an arm of the link 9, bending over the upper edge of the bar and descending on the rear side of the same. i The links and g together form a toggle-joint.

g is a laterally-moving link bar pivoted to a rear extension of the slide and to the end of the lever B. When the rake is moved outward, the arm 9 strikes the bar 0 and the toggle'joint is extended, the meeting points of the links passing the perpendicular. This motion lifts the rake and causes the links 9 to bind on the arm 9, the link g preventing the former link from falling backward. At the end of the inward motion of the rake a lug, Z, on the bar 0 strikes the arm g", and, bending outward the toggle-joint, allows the rake to fall. The compressor-cordf descends from the springf through a slot in the main frame, runs around the pulleys h h, journaled on brackets secured to the under surface of the main frame, and the pulley h, and is secured to a staple on the lower surface of the main frame. The pulley h isjournaled upon the inner end of a longitudinal bar, H, sliding in a slot, h, in the outer bar of the frame,and also supported by a stirrup, h", depending from the main frame. The said bar is provided outside the pulley h with the rectangular openings If h the'sides of which converge from above downward,and to the outer side of said slots, upon the under side, it has upon it the lug h having its .outer surface beveled, as shown.

I is a hollow block sliding freely on the bar H, and having secured to its lower surface the longitudinally-extending springhook i. The upper surface of the block has extending laterally from it the opposite arms or lugs, i and i, and centrally upward from it the pin i which enters a longitudinal slot in the inner end of a laterally-swinging link-bar, t, the outer end of which is pivoted upon the end of the S-shaped extension I) of the lever B. As the block movesinward,the point ofthespringhook i passes over t-helug h, the bar H being at rest, with a stop, its, on it, againsta part of the main frame; but when the block begins its outer motion thehook catches against the lug and draws the bar out till a stop, h, on the bar strikes against the main frame. The beveled holding-edge of thehook then slides over the lug, and the tension of the compressorcord and the spring f returns the bar H to its former position. When the bar H is drawn outward, the compressor-arm is down and the spring f is bent downward. The bar H is prevented from going too far inward by the hook j,pivoted upon abracket,j, on the main frame, and having its arm j pivoted upon the sliding bar J, the outer end of which is recessed on its edge and upheld by a bar of the main frame. When the block I moves inward, its lateral arm i strikes against the shoulder j on the lower edge of the bar J, thereby turning the hook j, and making its point enter one of the slots h. Vhen the bar-His drawn outwardly, the point of the hook rides over the slots. Arectangular opening is cut at the front inner corner of the platform, and a rectangularplate, K, is bolted to the main frame thereover. V

7c is a transverse depression in the plate K, into which the compressor-arm descends, and which guides the barf in its outward motion.

In is the transverse slot in the plate K, through which the binder-arm passes in its descent.

k is a rectangular slot extending longitudinall y of the platform from the rear end of the slot k, and serving a purpose hereinafter explained.

The plate K forms part of frame L, to which the holding, knotting, and cutting devices are attached.

To the plate K is bolted the upwardly-projecting flange of the vertical portion Z ofa plate, Z, which lies parallel with the plate K.

l isaplate parallel tothe platesK and Z,about vertical portion of the latter.

Z is a bracket depending from the plate Z, and having its edge bent at right angles inward.

Z is a guide-bar, secured at its inner end to the plate Z and at its outer end to the main frame.

M is ahollow vertical shaft journaled in the plates Z and Z. The upper end of the shaft M above the plate Z carries the horizontal jaw m, having on one side the curved and inclined shoulder m. The lower end of the shaft M below the plate Z carries the pinion m The iaw in and upper end of the shaft M is provided with the slot m N is a shaft passing through the shaft M. and having pivoted to its upper end the heel of a jaw, a, which forms the lower jaw of the knotter, the jaw at being the upper jaw of the same. Thejaw n is pivoted at n in the slots m The lower end of the shaft N carries the swiveled block it", provided with lateral arms carrying friction-rollers n n 0 is a hollow block reciprocating on the bar Z*, and provided on its rear side with the upright lugs O O, by engaging with which'the lateral arm i of the block I reciprocates the block 0.

o is a horizontal arm extending inward from the block 0, and carrying at its end a slotted bar, P. The bar P has on its upper and lower sidesthe straight longitudinal slots p10, the lower one of which is a guide-slot for the swiveled block a. On the sides of the frame P are midway between the same, and secured to the the similar longitudinal slot-s,pp, having the curved portions 1) 19 into which enter the friction-rollers n, so that when the said rollers pass over the curved portions 1) the shaft N is raised and the jaw 12 opened from the jaw m.

P is a straight rack-bar, made on the upper front edge, of the bar P, within the same, and engaging with the pinion m, so that as the said bar is reciprocated the shaft M (and consequently the shaft N are rotated first in one direction and then oppositely.

Q is a holder-wheel, journaled on the shaft M, immediately below the plate I, and provided with the teeth q.

q is a spring-hook secured to the block 0, extending inward therefrom, and having its point arranged to engage with the teeth q.

g is a flat spring secured to the lower surface of the plate Z, and acting against the teeth g on the-side of the wheel Q, opposite the hook q, so as to prevent the said hook from rotating the wheel as it moves inward. As the hook moves outward its point catches against a tooth and moves it outward, causing a'tooth diametrically opposite to bind the cord between itself and the plate Z".

R is a tucking-plate having a curved contour, with its inner edge concave. The plate R is pivoted on a vertical post, r, between the plates K and and has on its hub, which surrounds the said post, the shoulder 1", against which the spring r, secured to the plate 2*, acts when the plate R is rotated.

r is an arm standing inward from the boss of the pla e R, and risa spring-hook secured to the block 0, which slips over said arm when moving in ward, and draws the arm back when moving outward, till the inclination of the arm allows it to slip off and lets the spring r return the plate R to its first position.

S is a rectangular plate or stripper, moving longitudinally in ways on the under surface of the plate K below the slot k.

s is a cut-away portion of the plate B, which continues and completes the slot k when the plate S is at its farthest inward position.

8' is a lever-arm pivoted upon the under surface'of the plate K, and slotted to receive a pin, 8 depending from the plate S.

s is a reciprocating bar pivoted at its inner end on the pin 8, and provided with the Ion gitndinal slot 8* at its outer end.

s is a pin rising from the block 0, with its upper end in the slot 8', and reciprocating the plate S froln the said block. The function of the plate S is hereinafter explained.

T is the cutter-plate, lying upon the plate I, and having the cutting-edge t. The cutterplate is journaled upon the shaft'M, and has an arm, t',which is pivoted to a reciprocating bar, t, the outer end of which is provided with a longitudinal slot, t into which passes the pin t from the block 0, the said pin reciprocating the bar t, and actuating thereby the cutter-plate. The platel is cut away at U vertically below the slot k in the plate K, to allow the binder-arm to descend to the holder. 7

2 is a twine-guide bar having its ends bentdownward and secured to plate l, the said bar standing in such position as to direct the twine into the open jaws of the knotter. The twineguide 2 lies immediately above the cutterplate, the cutting-edge of which moves under it and over the recess or slot U in the plate I. The cord-guide 2 receives the cord as itis carried by the needle to the holder, and supports and guides it to the proper height to enter the jaws of the knotter. The gavel is pressed back against the compressor-cord by the grain-rake, and the compressor-arm descends in front of the gavel, carrying the cord down and compressing the gavel, the bar H being drawn outward to give the proper tension to the compressor-cord. The binder-arm then descends and passes the binding-cord around the gave], and the wheel Q advances one tooth and secures the binding-cord between itself and the plate Z. The shafts M and N have their jaws to the front of the machine, and the plate R or tucker turns the binding-cord to the side of the jaws, so that it engages therewith. When the jaws have rotated far enough to keep the cord from slipping off, the plate R springs back and the shaft M winds the cord upon itself. The shoulder mon the said shaft then causes the cord to slip upon the jaws m and a, forming the loop of the knot. When the shaft M has made about one. and one-half rotations, the jaws are opened by the action of the block n" in the slots 1), lifting the shaft N. The jaws are then in position to catch the binding-cord, which is directed between them by the bar 2. The guide-bar 2 is of the same height above the plate 1 as the shoulder m on the shaft M, and the cord consequently rises upon the guide-bar to that height and slides along the same into proper position to engage the shoulder, the bar having the proper inclination to permit this. After the jaws close on the cord the cutterplate T cuts the cord, and the jaws m and n rotate backward, the plate S drawing the loop off the jaws, thus forming the knot, and the jaws opening during their reverse motion to allow the escape of the severed ends. 1

The reel-adjusting mechanism shown,while forming part of the described machine, pertains to another class,and will form the subject of a separate application for a Patent bearing Serial No. 157,904, and of even date with the present application.

The cutting and conveying mechanism is situated sufliciently in front of the binding table and mechanism not to prevent the ac tion of the latter. The parts may be situated relative to each other similarly to the parts shown in a patent granted to me on the 30th day of October, 1883, N 0. 287,695.
