SPECIFICATION forming part of Letters Patent No. 279,101, dated June 5, 1883.

Application tiled February E9, D383 (Model.)

To Lil whom, it 77mg/ concern:

Beit known that l, DANIEL MoPHnnsoN, of Caledonia, county ot' Livingston, and State ot' New York, have invented a new and usetul Improvement in Grain-Binders, of which the Afollowing is ai'ull, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

`My invention relates toa novel means i'or separating the gavel to be bound from the incoming grain, and `for taking up the slack in l theband; to the means 'for taking the cord from the needle and carrying it into the notched cord-holding disk or wheel; to the means for lifting the portions ot' the band extending' around the bundle down past the knetter, and between said knotter an d the cord-hol der above the knotter t'or throwing the cord over the head ofthe revolving knetter and toi-.ming the loop, and to the means for. simultaneously lifting the cord-holder tor giving the necessary slack for forming the loop in the ends ot' the band, to the means for imparting a backward throw to the cord-holder for carrying the cord properly into `the cord-grasping hook ot' the knotter-head in the process ot' raising the cordholder t'or giving the neeessz-iry slack to `i'orm the loop, and for actuating and guiding the vertical, movements ot.' the cord-holder carrier, whereby the iirst movement ot' the latter in descending is in a vertical path for taking up the slack in the band, and avoiding the displacing of said band until the latter has been grasped' by the knotted hook or jaw ot' the knetter and to the combination, with said cord-holder carrier and knetter, of a rotating` knife andloop-stripper, the movement of which is so timed relatively to those of the knotter, hook, and cord-holder carrier as to cut the cord after the slack has been taken out of the knot,

. and the ends of the band have been grasped by the knetter-hook of the knetter; to the means for shitting the cord from one side to the other ot' the vibrating hook or arm which takes the cord from the needle and carries it into the cord-holder, and to certain details of `construction and arrangement hereinafter described.

In the accompanying drawings, Figure 1 represents an elevation ot' my improved knotting mechanism, taken from the stubble side of the machine. Fig. 2 is a front elevation,

and Fig. 3 is a rear elevation, of the same. Fig. 4 represents a vertical. longitudinal sec` tion in line with the shaft ot' the knetter. Fig. 5 is aside elevation ot' the knotter detached, with its actuating-pinions and hollow shaft in section. Fi (i is a top plan view ot'the knotter, and Fig. 'T is a bottom view ot the same. Fig. 8 shows in perspective the upper end of the knetter-shaft standard, with its cam for actu` ating the knetter-hook. Fig. 9 isa rear elevation ot' the toothed disk actuating the knotter, and Fig. 10 is a similar ele 7ation ot' the toothed segment actuating the revolving knife and loop-discharger.

The mecliianism employed t'or actuating the knetter .is similar to that described in Letters 'Patent granted to me March 5, 1878, No.

ment imparted to it in a manner and by mechanism similar to that described in Letters Patent. granted to me January 4, 1881, No. 236,347, and these `features, therefore, need not be described in detail i'urther than is necessary to ex plain my l'nesent improvements and their connection with said parts.

A A represent uprights of the frame oi' the elevator, by means of which the grain is earried over the main drive-wheel to a conc-z ve receiver or binder-table on the outer side ot' said wheel, said frame and elevator, together with the reaping-machine to which they are connected, being ot' any usual or preferred construction.

B 3 representan upright rectangular frame, in whichthe binding mechanism is mounted or supported, said frame being suspended on the outer side ot' the drive-wheel upon pivots at a, and ai', connecting it at its upper inner corners with the upper ends of the uprights A. and A ot' the elevator-frame, the arrangement being such that the binder-trame can be turned over upon the elevator for transportation or t'or passing through narrow gatesor passages. The lower and inner longitudinal timber, B', otcthe binder-frame has itsends extended to form stops b I, which rest against the lower ends of the uprights A and A', and serve to prevent said frainei'rom swinging inward beyond a proper working position when in use. The upper part ot' the frame B B `is provided with. suitable bearings for the mechanism through which an orbital movement is im? 200,868, andthe needle has an orbital move IOO parted to the needle C, which movement and mechanism, being similar to that described in my patent of January +L, 1881 above referred to, need not be here described. To the upper end of this needle is pivoted a pendent rod, C, forming a grain-separator and cord take-up for separating from the gavel to be bound and crowding backward therefrom the grain coming into the concave receiver behind the needle after thelatter has passed down through the grain for carrying the cord to the knotter, and also for taking up the slack in said cord. rlhis rod C rests against the rear face of the needle C, 4its lower end by preference resting in a groove in the lower end of said needle in such manner as to adapt both to pass down through the grain together and prevent the grain from getting between them. The cord or other band material passes from a spool arranged on the inner side of the frame B through an eye, c, inthe needle, thence through an eye, a', in the point ofthe take-up rod C and back through an eye at c in the point of the needle Y (l, and thence to the cord-holder underneath the grain-receptacle, hereinafter described. Upon a transverse bar, B2, of the frame B, at or near the center of its length, is secured a stop-pin or standard, b, and the separatingrod C is provided on its side, near its upper end, with a pin, c, which, as the needle is carried downward and outward for carrying the,

cord to the cord-holder, comes in contact with the stop b', and serves, as the outward movement ofthe needle (l is continued, to impart a positive movement to the lower end of the rod C for moving the incoming grain back or inward awa-y from the outwardly-moving needle, and also for taking up any slack inthe band". The rod C is retracted into its former position against the needle, when released from the stop b, by a spring, c, surrounding the pivot through which it is connected with the needle. A. grooved cam or other suitable means maybe substituted for the stop and spring for imparting the movements described to the rod C.

D is an upright rectangular frame, in which the knotting devices and their actuating mechanisms are mounted, said frame being rigidly secured at its lower end to the outer longitudinal timber or flooring of frame B. This frame is provided with bearings for a longitudinal driving-shaft, E, and at its upper endV with a vertical sleeve, B, forming a bea-ring for the tubular shaft F of the knetter, the inner solid shaft,.l having its bearings in the tubular shaft. rlhe shaft E serves to actuate the binding mechanism, a-nd is geared to and actuated from the main drive-wheel ofthe reaper in any suitable manner. Other shafts hereinafter described have also their bearings in suitable lugs or arms ofthe frame D.

Upon the shaft E is secured a cam and gear wheel, G, upon which are formed a number of toothed segments and a cam and pin or eccentric, for purposes which will be explained.

- The frame D is provided with arms to form bearings for a short shaft, E, on which a spur gear or segment, G, engaging with and actuated from a toothed segment, g, on the wheel is secured, said shaft E being provided on its forward end with a crank-arm, e, the wristpin e of which enters a horizontal slot, 71, in an arm of a sliding plate, H. This plate H is provided also with upright slots h and h2, vertical in their lower portions and inclined or curved outward from the knotter at their upper portions, through which slots the plate H is secured to the forward standard ofthe frame D by headed pins which permit the vertical and lateral or inward' and outward movement of the plateiH, actuated by the crank-pin e and guided by the form" of the slots h and 112. The upper end ofthe plate H is provided at h?" with bearings for the horizontal shaft of a rocking finger, f, which projects inward within the path of the needle C. This projecting finger is made in angular or crank form, and its point is acted upon by an incline formed at c* on the side of ofthe needle, the point of the finger serving to takethe cord from the needle, and then, being rocked toward the knocker by the latter, to carry said cord to and into the cord-holding devices. The finger f, after it escapes from the needle, is retracted to its former position,

for adapting it to again seize the cord, by a c spring, fl, surrounding its shaftj".

rIhe/cord-holding device consists of a forked arm, if, formed upon or secured to the upper end of plate H, at its inner edge, and a toothed cord-holding wheel and attached ratchet-disk, vi, mounted in bearings in the fork of said arm. To thel forward face of the plate H is pivoted an arm, l, provided with a projecting pin, if, which is acted upon, once in each revolution of the shaft E, by a cam or eccentric, E2, fast on said shaft in front of the frame D. To the swinging end of the arm l is pivoted apawl, I', the outer or free end of which engages the ratchet-disk fi, and serves to move or rotate said disk a distance equal to the length of one tooth of the cord-holding wheel at each throw of the pawl. rlhe pawl is retracted for repeating the operation by any suitable arrangement of stop on the frame D, said stop acting on the pin f near the upper end of the throw of plate H. The rocking movement ofthe cord-finger f described carries the cord in between the teeth ofthe cord-holding wheel, and the movement of the latter, as described, carries said cord in between said wheel and the sides of IOO IIO

IZO

the forked arm 71,4, thereby grasping and holding said cord. In this movement the portion of the cord grasped by said toothed wheel, and

bearings et The outer end of this` shaftE` is provided with a'rearwardly-projecting linger,

e, which overrides the cord-fingerf, and serves to carry the cord inward toward the knetter until it clears the .point of said finger, when the tensionon said cord draws it intoproper and the knetter, for a purpose which will be explained.

L is a vertical rock-shaft mounted in suitable bearings in outwardly-projecting arms of the frame D, and provided near its lower end with an inwaidly-projecting arm, L, which is acted upon by a cam, l, on the wheel G, for rocking said shaft L. The shaft L has an ar-m, L, on its upper end, which, by the rocking movement of the shaft, serves to carry the portions ofthe band lying between the cordholding wheel` land the bundle in within reach of the cord grasping and looping hookon the knetter, as hereinafter explained.

M is an upright shaft mounted in suitable bearings on the rear standardof the frame D, and provided near its lower end with a bevelpinion, m, which projects through an opening or slot in the rear upright or standard of frame D, and engages with a beveled segment, fm?, on a plate or disk,M, fast on the shaft E, and which at each revolution serves to impart a single revolution tothe pinion m and shaft M. A plate, nl?, on the shaft M, below the pinion m,

`provided with a flattened surface on one side,

which rests against the adjacent face of the disk M/ in the intervals between t-he action of Y the segment m on the pinion, serves to prevent accidental displacement of the pinion m and shaft M and to hold them in proper position to be acted upon by the segment m on itsnext round.

To the upper end of the shaft H is secured an arm, M2, of a length sufficient to enable it to reach over the knotter, moving in close proximity thereto,.and provided at its outer swinging end with an angular extension, m, terminating at its lower end in a knife or cutter, mt, theofiice of which arm and cutter is to cut the cord and simultaneously to slip the loop` otfthe jawsof the knetter and over the ends of the cordgrasped by the knetter-hook, as will be eX- pl'ained. The arm mZ sweeps over theknott-er, and the pendent or angular extension m thereof serves to support the knife fmt below the plane of said head and to bring said arm into proper relation to the hooks or jaws of said rI heknott-er is composed of th ree parts-wiz.,

the cap part or head N, rigidly secured to the upper end of the inner shaft, F', the cord grasping and looping hook N, rigidly secured to the outer tubular shaft, F, and a second or knotting hook, N2, pivoted to and revolving with `the grasping andlooping hook N,but adapted, through its pivotal connection therewith,to receive a lateral independent vibrating Inovement for enabling it to grasp and hold the end portions of the band to be drawn through the loop in forming the knot. The hook ik is provided (see Fig. '7) at orvnear the center of its length (from its pivot to its point) with an inwardly-proj ecting spur, yn, which prevents the cord from being carried too far back between the hooks N and N2. .The hook or pivoted jaw N2 is further provided on its heel extension, beyond its pivotal connection with the hook N, with a pendent pin carrying a friction-roller, i1', which works in a cani-groove formed von the upper end of the sleeve-standard D. (bee Fig. S.) This cani is doublewalled, consisting of an inner wall, p, crescentshaped and partially surrounding the knottershafts, for acting upon the friction-roller `u to close the hook N`` on the hook or j aw N', and an outer wall, p, on the sleeve-bearing D, opposite the part of least eccentricity of the cam )9,for crowding said roller inward toward the k netter-shafts and opening the hook or jaw NL. This outer Vall, p, of the cam-groove is shown detached from the sleeve-standard D', and adapted to be secured thereto by means of a screw or equivalent fastening passing through a perforated lugor car, p2, into said vone piece with the standard or applied there- .to in any preferred manner. rlhe cap portion or h ead N of the knotter is partly cut away on one side, and has a pendent lip or jaw at n,

is grasped, and is by preference made convex on its upper face to facilitate the forming and clearance ofthe loop.

Motion is imparted to the knetter by means of beveled pinions F`t and F3 on the lower end of its shafts F and F, respectively, engaging with toothed segments on the wheel G, as follows, viz: at g a short segment of sufficient' less) to the pinion F2, shaft F, and hook or jaw for grasping the two strands ofthe cord reaching from the holder around the bundle; a long ofthe teeth of segment g', for actuating both .pinions F'Z and F simultaneously and impartvling three-quarters of a revolution (more. or

its cap or head N for carrying forward the j aw al and opening the hook N for releasing the cord and leaving the hook N open preparatory to forming a new loop. The concave receiver or table which receives the grain from the elevator and in which the grain is bound will have N for adapting it to close against the jaw of,

segment at 92, with the teeth of double the widthV IOO sleeve-standard at b2,- but it may be formed in between which and the hook or j aw N the cord length to give a quarter-revolution (more or 1 2 5` less) to the ent-ireknotter for forming the loop in the cord, and another short segment at g3 for giving a quarter-revolution to the shaft F and necessary slack for forming the loop.

Qver and above the knetter.

a transverse slot formed in it, permitting the passage of the needle in .carrying the cord around the grain therein to the cord grasping and holding disk or wheel.

The operation is as follows: Supposing one end of the cord to be held in proper position by the cord-holding wheel, and the cord by the orbital movement of the needle to have been carried around the grain in the concave receptacle, the rod C' and the cord-finger f, acting as hereinbefore described, the former for separating the grain and drawing the cord tightly around the bundle, and the latter for picking the cord off the needle and carrying it into the cord-holding wheel, bythe rotation of which it is seized, as explained. Thus the two ends of the band surrounding the bundle in the concave receptacle are held by said wheel. At this instant the arm L? is vibrated to carry the portions of said cord extending between the concave and the cord -holding wheel to within the sweep of the hoeklor jaw N', which is new carried through a quarter of a revolution by the action ofthe segment g' on the pinion F2, causing the cord to be grasped by the knetter between said hook and the jaw u2 of the cap or head N. At this instant, and in the interval of rest given to the knetter, due to the space on wheel G between the segments g' and g2, the curved arm k2, underlying the cord between the knetter and the cordholding wheel, is lifted by the action of the pin k" for raising that portion ofthe cord lying between the holder and knetter and throwing it At this point, the double-width segment y" having reached the knetter-shaft pinion, the knetter is started on a movement of three-quarters of a revolution, more or less, the cord-holding wheel holdin g the ends of the band having in the meantiine been lifted through the action of the crank-pin e' on the plate H for supplying the As the knetter begins its movement described the hook or jaw N2 is opened by the action of the cam-wall p', and the cord-holding wheel begins its downward movement in a vertical path for drawing the loop tight, and` at the same time holding the cord extending from over the cap or head N in position to be' grasped between the hook N2 and the hook N' before the knetter' completes its three-quarter revolution referred to, and said hook is closed upon the cord by the action of the inner wall, p, of the cam thereon. The downward movement of the cord-holder is first in a direct vertical path, due to the form f the slots h' and h2, to avoid V.drawing the cord out from between the jaws or hooks N' andN2 in taking up the slack prior to the closing of said jaws orl hooks one on the other. At or about the instant the jaws N'- N2 have closed firmly on the cord the segment g3 acts on the pinion F3 and shaft F', carrying forward the jaw vn2 a quarter-revolution, opening the hook N', and at the same time, the arm k2 having been released from the action of the pin l5- and removed out of the path of the arm M2, 'the latter is caused to rotate, carrying the knife m, the latter cutting the cord below the plane of the knetter and between said knetter and the cord-holding wheel, the pendent arm, to which the knife m* is attached, at the same instant slipping the loop over the ends or points of the hooks N' and N2, and over the ends of the band grasped and held between said hooks, vas explained, and which are thus drawnthrough the loop, forming the knot.

Having now described my invention, what l claim as new isy l. The combination, with the needle, of a combined vibrating grain-separator and cordtake-up rod pivoted to and moving with said needle, and means for intercepting the rod, so that the continued forward movement of the vneedle shall impart a positive backward movement to the swinging end of said take-up rod, substantially as and for the purpose described.
