GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 423,389, dated March 11, 1890.

Application filed February '7, 1889. Serial No. 299,053. (No model.)

To all whom if/ may concern:

Be it known that I, MARION L. NICHOLS, of New York, county of New York, State of New York, have invented new and useful Improveparting an accelerated movement thereto by and in the operation of adjusting the binding devices, described in Letters Patent granted to me January 8,1889, No. 395,991.

The invention consists in pivoting the grain trip-arm to overhang the grain-table and in connecting said arm directly with the triparm controlling the clutch` mechanism between the continuously-operated main packers and the intermittentlyoperated separator.

It further consists in a novel construction of clutch-lever controlling the auxiliary packers to be acted upon by the separator-arm, whereby said packers are thrown out of action by the direct engagement of the separatonarm with the clutch-lever.

It further consists in combining the separator, controlled in its action by the graintrip, with the auxiliary packer-clutch and binder-mechanism trip in such manner that the separator shall at its first impulse act to throw the auxiliary packers out of action, and at the completion of its forward movement to throw the binder-trip into action.

It further consists in connecting and operating from the auxiliary packers a butt hastener or forwarder for engaging the butts of the grain and carrying them forward into reach of the auxiliary packers.

It further consists in a novel construction of slotted pivoted yoke or frame arranged to engage the pawl which locks the pinion through which the binding mechanism i`s operated to its shaft, whereby the same'is held positively until acted upon by the separatingarm.

It further consists in a novel manner of connecting the header board or flag with the binder and the means for actuating the same,

and to certain details in the construction and arrangement of part-s, all as hereinafter described.

In the accompanying drawings, Figure lis a perspective view of the binding-mechanism ,frame with the knotting devices removed. Fig.

2 is a perspective view of the same with the knotting mechanism removed, showing a portion of the main frame of the machine and the means for connecting the header board or iiag mounted on the main frame with the binder-mechanism frame. Fig. 3 is a side elevation of the grain trip-arm, the mechanism for imparting motion to the separator, the trip mechanism for throwing the separater into action, and the secondary auxiliary packer-arm. Fig. 4 is a plan or top view of the shaft for communicating motion to the main auxiliary packers and the mechanism for throwing the same out of action. Fig. 5 is a perspective view of the lever for throwing the auxiliary packers out of action. Fig.

'6 is a perspective view of a portion of the binder-mechanism frame, showing the end of the shaft for communicating motion to the packers, and the pinion mounted thereon, through which motion is communicated from said sha-ft to the binding devices, and the devices for unclutching said pinion from the shaft and holding it out of action. Fig. 7 is a top view of the same, and Fig. 8 is a perspective view showing a modification of the manner of operating the contractible ejectorarm..

The main and auxiliary packers, the separater, and the several trip mechanisms are mounted in the binder-frame, which consists of the arching rear frame B4, connecting-bar B2, upper tubular cross-bars B B and lower tubular cross-bars B B', and frame-bars B3 B3, to which the breast-plate C is connected, constituting the movable binder-mechanism frame, and which is mounted upon and adapted to move on traekways a5 on the bars A of the harvester-frame, the lower bars B B being provided with rollers B5, which engage said trackway, the other parts of the harvester-frame herein shown, but not particularly described, being constructed in any usual or preferred Way.

The shaft G', which communicates motion IOC to the main packers, auxiliary packers, and separator, is mounted in one of the tubular frame-bars B, and has loosely mounted upon it near its outer end a pinion G7, having a disk or plate G8 secured thereto, and carrying on its outer face a rock springpawl G9. This pawl is provided with arms n n n2, from oneof which projects a lug n3.

On the shaft G are rigidly secured the packer-wheels G12, only one being shown, and from the inner face of the outer one (the one shown) project friction-rollers m15, to engage the lug n3 of the pawl G9, and through which engagement to cause the pinion to be engaged with its shaft, as described inthe patent before referred to. Upon. the opposite end of the shaft G is mounted a sprocket-wheel I, having an enlarged hub or disk I formed therewith, and from the outer face of which disk project friction-rollers n, and adjacent to this Wheel the shaft G has loosely mounted upon it a pinion I2, also having a hub or disk W7 formed thereon, and on which disk is pivoted a rocking spring-pawl h5, having an arm, (not shown,) from the side of which projects a lug. (Not shown.) The pinion I2 transmits motion when engaged with its shaft to the mainbinder-mechanism gear I3 through an intermediate pinion I4, mounted in suitable bearings w11 in the arching frame B4.

The packer-wheels G12, which are mounted 'on the shaft G on each side of the framebars B3, have pivoted to them the angularlyformed packing arms or fingers G10, which arms are pivoted upon the side faces near the periphery of the wheels, and have at their points ofanglcs projecting therefrom lugs g5, to engage cam or trackway G17, se-

cured to the shaft G or to the frame in any preferred way.

A shaft L, parallel with the shaft G', is mounted in the frame B3 in front of said shaft G', and at a point over the inner end of the carrier or apron, and has mounted upon it the separator L9. 'This separator has an vextension or arm L10,which is connected through a link L11 with a pinion L12, meshing with and driven from the pinion G7, and in the movements of the pinion L12 acting through the link to force the separator outward toward the carrier to catch and hold the incoming grain and divide it from that accumulated to form the bundle.

An arm or lever E is mounted in suitable guideways in the frame B4 and has pivoted to it a lever E', which is also pivoted on the frame, and this lever E carries on` its outer end a friction-roller (not shown) to engage and be engaged by internal and external camfaces e e', formed upon or connected to the binder-mechanism drive -wheel I3, and by means of which the lever, and through it the trip mechanism, is held, after being thrown into action, positively during the time the tying mechanism is in action, as described in the patent before referred to. The lever E has connected to it at a point between its pivot and its point of connection with the upright arm or lever E a spiral spring e2, which is connected at its upper end to a screw-threaded rod e3, mounted in a bearing in the arching bar of the frame B4, and which rod has mounted thereon a thumb-nut or handle e4, by which the tension of the spring on the 'lever E may be adjusted to regulate the size of the bundle, as described in the patent before referred to.

Mounted in bearing f f in the frames B3 B4 is a hollow shaft H, and within the hollow shaft is mounted a rock-shaft H6. This rockshaft H6 has mounted on one end, or that adjacent to the arching frame B4, a crank-arm H8, which crank-arm is connected to the upright arm or lever E, and has mounted on its opposite end a crank-arm G2, to which is cou-- nected a bifurcated or forked arm G4, pivoted to the frame B2 at a point above the shaft G. One arm extends down on each side of the shaft G', and each arm is provided with a lug b h', projecting inwardly from its lower end and into the path of the pawl G9. An arm D extends from the frame B3 and has a depending arm D connected thereto to lie closely to the inner face of the bifuroated or forked arm G4, and which arm D at its lower end is'provided with an elongated slot d, through which the lug h of the bifurcated arm passes. The trip-arm G4i is pivoted to the under side of the breast-plate, having its heel end project up through a slot in the same, and which heel end is connected to an arm GX, projecting from the bifurcated or forked arm through a link G5.

A link G13 is connected to the separator and extends back therefrom, and is in turn connected to a crank-arm G14, keyed or otherwise secured to the hollow shaft H, and through which connection to rock said shaft as the separator is thrown forward to catch and hold the incoming grain. The link G13is provided with an elongated slot G15 at its point of conneotion with the crank-arm G14, which slot is for the purpose of permitting the separator to move nearly the full extent of its Vthrow in acting on'the grain before the link G13 acts on the crank-arm.

A crank-arm h is mounted on the hollow shaft I-I adjacent to the frame B4, which arm is connected to a double-crank shaft H H2, having its bearings in the frame B4. One of the armsH engages the crank-arm h through a slotted connection, while the opposite arm H2 of the shaft extends outtherefrom in an IOO IIO

opposite direction to the arm H and engages a slotted yoke H4, pivoted on the frame B4, and located thereon in such position that the end of the yoke shall be in the path traveled by the pawl h5, and by the engagement of said yoke withl the arm h4 of said pawl to throw and hold the binder-operating gear out of action with the sprocket-wheel, as described in the patent referred to.

A set-screw P passes through a perforation in the frame, wherethe sleeved shaft has its bearings, and by its engagement therewith serving, by frictional contact, to produce a tension on the binder-clutch trip.

The auxiliary packers L8 are mounted and driven from crank-arms M on the auxiliary packer-shaft L, on which the separator is mounted, and motion is communicated to said shaft. from av sprocket-wheel (not shown) on the main packer-shaft G through a sprocketwheel M3, mounted loosely on the shaft L. This sprocket-wheel M3 is provided on one side with a hub havinga ratchet-face Z, which is caused to engage a corresponding ratchetface Z on the hub of one of the cranks to which the auxiliary packers are connected,and which hub is iixed to the shaft, and the sprocketwheel is provided on its other side with a .hub or collar Z2, with which a shipping or switch lever N, hereinafter referred to, is connected. A spring N engages the hub of the sprocket-wheel and serves to force the clutchfaces into engagement, and the lever serves to force and hold the clutch-face out of engagement and permit the sprocket M3 to run loosely without communicating lmotion to the shaft L. A

The switch-lever N is made inv angle form and is mounted on a pivot n on the frame, and has one of itsarms to engage the collar or hub Z2 on the hub ofthe sprocket-wheel,

while the other arm extends to and into position to be engaged by an arm L, projecting from the separator-arm L9. The arm L5 projects from the separator at such point and the engaging face of the lever N is curved in such manner that the separator will act upon thev switch-lever to throw the auxiliary packers out of action immediately in commencing its downward movement, so that the separator-arm shallnot be forced to act upon grain being carried in by the packers or that the packers shall be thrown out immediately upon the separator beginning to rock.

Mounted on the auxiliary packer-shaft and keyed thereto is a sprocket-wheel O, which engages through a suitable chain 0 with a sprocket-wheel O'2 on a crank-shaft O3, carrying a butt-hastener O4, which acts to engage the butts of the grain and carrying them into reach of the auxiliary packers, the upper end of said hastener O4 being connected through a link O5 to any convenient point of the binder-frame, and from which it will be seen that the auxiliary packers and the butt-hastener are thrown simultaneously out'of action on the first movement of the separator when said separator is thrown into action by the trip mechanism controlled .by the grain accumulated to form the bundle The shaft by which the knottcr mechanism is driven passes through 011e of the tubular cross-bars B, and has mounted thereon the ejector-arms, only one being shown, and to bring the parts into proper workin g relation said cross-bars B are brought closely together,

and to provide for an ej ector-arm which shall be of sufficient length to properly eject the bundle and at the same ltime pass the crossbar on which the main packers are mounted the ej ector-arm is constructed and acted upon in'the following manner:

On the frame,in line with one of the ejectorarms, is arranged a cam or track R, and the ejector-armv R is provided with a sliding spring-extension R2, fitting in a socket formed in the end of the ,main portion. The vmain portion R is provided with an elongated slotp, and the extension is provided withoutwardly-projecting pins p p2, engaging the slot j), to hold the extension engaged with the main portion, and said pins regulating the extent of movement of the extension, a spring p3, mounted in the main portion, engaging the extension to press the same outward, and the cam or track R engaging the point toforce the same into the slot against the action of the spring.

In Fig. 8 is shown a modiiicationin the manner of operating the extension of the ejector-arm R', in which case an irregularlyformed trackway is fixed to the bar B, and the extension R2 is provided with a pin to engage the trackway, which is so formed that the extension will `be drawn in or forced out at the proper time as the shaft carrying the ejector-arm is revolved.

Mounted on a cross-frame bar T yof the frame of the harvester proper adjacent to the movable binder-frame is a frame S, which has a bearing S formed in its upper end,in which IOO the rock-shaft S2, carrying the header board or flag '1" is mounted to oscllate, and upon which shaft is mounted an arm or'lever S3, having at its lower end a pin projecting at right angles to the main portion, and which engages a link Si, connected to the binderframe, which is adapted to be moved by means hereinafter described. The link at the point of connection with the lever S3 is provided with an elongated slot, which permits the binder-frame to bemoved within certain limits in both directions without acting on the header board or iiag. A lugS5 projects from the inner face of the lever S3 a short distancebelow its point of connection with the shaft S2, and to which is connected one end of a spiral spring S, the other end of said spring being connected to a lug S7, projecting from the cross-bar T directly below and in line with the shaft S2, and which spring forms an elastic connection between the lever S3 and the frame, in a manner that will be readily understoodb Mounted on the rear frame-bar A of the harvester-frame proper is a segment-rack V, having pivoted thereto a lever V', which has connected thereto a spring-pawl V2, connected to a handle V3, mounted on the end of the lever, the lever being arranged within convenient reach of the drivers seatVA A link X is connected to the movable binder-frame, about centrally of the Width thereof, to a suitable lug w, formed thereon or connected thereto in any suitable manner,

IIO

and which link extends back and is connected to the operating-lever, and by means of which connection with the lever the binder- -A Io frame may be adjusted in. relation to the canvas or carrier to adapt the machine to long and short grain, in a manner that will be readily understood.

The action of the device for connecting the header board or flag with the harvesterframe and binder-frame, as above described, is similar to that described in the patent before referred to, or so that an accelerated movement is imparted to the header board or iag in the movement of the binder-frame in such manner that as the binder-frame is moved forward to provide for short grain the header board or tlag'is caused Vto maintain a position relative to the needle about equal'to the distance between the needle and the line of the cutters, and thus insure the tying of the grain centrally, as will be understood.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is- Y 1. .The combination, with the continuouslyoperating packers, the intermittently-operating separator, the trip controlling the clutch mechanism between the continuously-operating packers and the separator, and a graintrip acted upon by the grain accumulated to form the bundle mounted to overhang the grain-table and connected directly with the clutch-trip, substantially as described.

2. The combination of the auxiliary intermittently-operating packers, the clutch-lever for throwing the same out of action, and the separator-arm acting to throw the auxiliary packers out of action by the direct engagement of the separator with the clutch-lever, substantially as described.

3. The combination of the separator controlled in its action by the grain-trip, the auxiliary intermittently-operating packers, the clutch mechanism for throwing the auxiliary packers out of action, and a binding-mechanism trip, substantially as described, whereby Ythe separator is caused at its first impulse to act to throw the auxiliary packers out of action, and at the completionv of its forward movement to throw the binding-mechanism trip into action, as set forth.

4. The combination of the intermittentlyoperating auxiliary packers, a butt-hastener, and mechanism for operating the same, and a clutch mechanism'for throwing both said auxiliary packers and the butt-hastener out of action before the binding mechanism is thrown into action, substantially as described.

5. The combination of the pinion through which motion is communicated to the binding mechanism, a pawl for engaging the same with its operating-shaft, and a slotted yoke or frame to engage the pawl, and a separator acting through intermediate mechanism on the yoke or frame to release the pawl, substantially as described.

6. The combination of the header board or ilag mounted on an oscillating shaft having its bearing on the main frame ofthe harvester, a depending leverconnected to said shaft, a movable binding-mechanism frame, and a link connected to the binding-mechanism frame and to the lever below the point of oscillation, substantially as and for the purpose set forth. l

7. The header board or iiag mounted on an oscillating shaft having its bearings on the main frame, a depending lever connected to said shaft, a spring connected with the lever and with the main frame in the same vertical plane with the shaft, and a link connected to the movable binder-frame and to the lever, substantially as described.

In testimony whereof I have hereunto set my hand this 31st day of December, A. D. 1888.
