Be it known that I, EARL G. WATROUS, of Smiths Mills, in the county of Chautauqua and State of New York, have invented certain Improvements in Grain-Binders, of which the following description, in connection with the accompanying two sheets of drawings, constitutes a specification.

. miliar with the art that it has hitherto been p of the cord-holder and cutter, with a vertical This invention relates .more particularly to the knotting, grasping, and band severingdevices of automatic grain binders, and has for its-object the simplification of these parts.

To this end it consists more essentially of the combination with'a revolving knotter of a stationary grasper so formed as to give the requisite amount of twine to theknotter to wrap the hook. It is well known to those fafound necessary to move the knotter toward the cord-holder, or the latter toward the former, when the loop is being made in the bands to provide suflicient slack in the grasper end of the band. As in my devices, this movement of either the grasper or knotter is obvi ated, and allmechanism to produce such.result done away with, the advantage of the invention is apparent.

.My invention further consists in certain other details of construction and combinations of parts as will be more fully hereinafter described and pointed out in the claims.

.My binding apparatus may be attached to a harvester so that the knotting apparatus will be either above or below the binding platform.

In the accompanying drawings I have shown the knotting apparatus located above the binder table, and the needle adapted to ascend from beneath the binding table or platform.

In the drawingsfln which similar letters of reference indicate like parts, Figure l is a side elevation, only so much of the binding apparatus being shown as is necessary to illustrate my invention. Fig.2 is a top plan view of the cord holder and cutter, the knotter, and thebreast-plate. Fig. 3 is a front elevation cross section through the knotter driving disk.

lever. Fig. 5 is a rear side elevation of the same. Fig. 6 isa side elevation of stationary member of the cord-holder. Fig. 7 is an end elevation of the same. Fig. 8 is a top plan view of a portion of the breast-plate andthe tucker. Fig. 9 isa sectional view of the knotter. Fig. 10 is a view showing the shape of the cam on the kno'tter driving disk, which cam is shown extended in a straight line, and is for the purpose of determining the various positions of .the knotter. Fig. 11 is an end elevation of the grasper lever. Figs. 12 to 16 inclusive are views illustrating the formation of the knot. Fig. 17 is a side elevation of the knotter: driving-disk. Fig. 18 is a perspective of the grasper lever, having a knife, stationary therewith, attached thereto.

A is the intermittently operatedreciproeating binder arm shaft to which motion is imparted from some suitable part of the harvester in any well known way.

B is the binder-arm or needle secured rigidly to the shaft A, and is adapted to the band to the knotter.

L is the breast-plate.

P is the knotter driving disk, and is secured to the intermittently operated binder shaft 0, to which onecomplete revolution is given to each operation of the binder.

K is thecord-placer.

Both the cord-placer and the breast-plate are made preferably of thin sheet. metal, in order that the knot may be tied as closely as possible to the bundle.

B is the knotter-hook. Its spindlehas a bearing in the knotter-frame A ,andcarries at its upper end, rigidly secured thereto, the bevel pinion Q and the delay-shoe S.

The driving disk P is provided with a segdeliver mental rack near its periphery which is of a 4 reference to the knotter.

ward end of'which is free and plays up through a slot h in the upper jaw d", as clearly shown in Fig. 9. The lower side of the forward end 70 of the spring K" is hooked to catch the ends of the band, and the forward end of the spring K" is beveled so that as the cords enter between the jaws g and d, the spring will be forced up to permit the bands to pass, when it will afterward clamp the ends against the lower jaw g. The loop, which has, by the revolution of the knotter, been wound around the jaws g and at", will in being pulled 01f the jaws impinge upon the upper part of the spring K, as shown in Fig. 16, and theends of the band will be thereby firmly held in place between the jaws until the knot is tied.

The breast-plate L is suitably slotted .to

permit the needle to pass, as at M. From M,

the slot is narrowed, as at f, to more surely guide the band to the proper position with aroundfromf at g,-in-the direction the bands arecarried by the knotter hooks. From g-the slot is curved around, as at N, to the more readily permit the knot to be stripped from :the hooklby the stress of the outgoing-sheaf. The=slot in the breast-plate terminates in the "opening 0, against the ends of which'the swingingmember of the cutter abuts, to open 'and 'close the shear-blades. When the knife is used in lieu of the shear-blades the rectangular opening 0 is obviously unnecessary.

The essential features of theforin of the slot in the breast-plate are that it should be wider at M, to permit the ascentrof the needle; should. be narrowed at f to guide the band into the desired position with reference.

'to the knotter, and that it should then sweep around so that when the knotter has performed about three-quarters of a revolutionthe slot should'point in the same direction as the jaws of the knotter.

The tucker isadapted'to so confine the twine that when the knotter commences to.

revolve the bands will be surely held so that they will be wrappedaround the hooks.

A is the tucker lever. It is fastened at its upper end to the elbow lever B by-a bolt 5 vided with a cam- 0 which in the revolution which passes through a segmental slot in-the lowerend of the lever B. -By these means 'theadjustment of the tucker is effected. The elbowlever is pivoted to the frame of the machine at a and carries at its upper end the friction roller D The driving disk Pis profastened to the lever A, as shown in Fig. 1,v

gles-to the lever A and is notched, as shown at 2'. This notch is adapted to receive the cord, and when the tucker is moved forward by the cam 0 which occurs'somewhat prior to the revolution of the knotter, the cord is confined in the openingj betweenthe tucker and the edge of the slot in the breast-plate, as shown at Fig. 8. In this way the cord is surely caught by the knotter and --wound around the jaws. This notch i in the tucker prevents the cord from being pushed away from the jaws of the knotter, and its importance will be readily apparent to any one skilled in the art.

U is the grasper lever. Itis elbow-shaped, as shown, and is pivoted to the frameV at the elbow of the lever. The upper arm .U carriesa friction rollerT mountedrthereomwhich friction roller traverses a'cam'ggroove 'I I formed on the face of the-.knotter driving disk. The lower endo'f the lever U is :bent outwardly-therefrom, and is formedintoa curve from thepivoted point-offattachment of the lever U to the frameVasacenter. Thelower part of the lever 'U carries'the-bandsevering devices. The lower horizontal arnrof the cord-holder isdesignated lc'i'n the drawings.

A fixed shear-blade'r is rigidly attached to the lever U, and may be provided with a cutting edge. Another shear-blade m is pivotedto the fixed shear-blade and has a dependent arm 0 which extends downwardly into the transverse opening-in the breastplate. It will be evident thatas the lever U reciprocates, the arm o striking one :edge of the opening 0 will open the shear-blades to receive the twine,and striking the otherend of the slot will close the-shear+blades:to sever the band.

In Fig. 18 I have shown a stationary knife 0 attached tojthe lever U. The forward end of this knife is'provided with asharpened edge, which being moved against the bands sever them. It is obvious that whenthisknife is used in lieu of the shear blades, thetransverse opening Omay be done away with.

W is -the-stationary member of the cordholder. Itis rigidly bolted to the frame. Its lower portion is formed-seas to 'be 'concentric to the limb of the leverU. It is made with two lips or flanges w w, in the groove 2) between which the limb or tongue plays. The lip ,w, or the one farthest fromthe knotter, has

a hooks formed thereon'for the-purpose hereinafter described. The tongue 70 is formed with a shoulder y, which, when the lever U is swung away from the part W, receives the cord delivered by the needle, and when vthe lever U is moved inwardly carries the cord in between the lips or flanges w w. The lower limb of the lever U carries also .asecond shoulder Z, which, bearingagainst the cord as the lever is swung inward, surely carries the cord beyondthe hooks. The shoulders y Z are on the opposite sidesof the flange w. The purpose of the'hooks is to prevent the cord being drawn out of the hold of the grasper ICC by the rearward movement of the lever U- This is very important, inasmuch as'it is necessary that the leverUbe swung backwardly at the commencement of the revolution of the knotter, in order to allow sufficient slack in the-grasper end of the band to wrap thehook. Itisof course immaterial whether the knife 0 be attached to the fixed member W or to the swinging member U. If attached to the former, a "shoulder m should be formed on the lever U- between the cord-holder and the grasper,-to force the band against the knife "V; and iftheknife is carried on the lever U,

the shoulder should be formed on the stationary member of the cord-holder. It is obvious that for the purposes'of the present invention thesethree devices are fully equivalents,

and it'matters not which one is employed. The cord is held in the grasper by being passed between the tongue k and the groove '0, and'also by being kinked or bent-over the lip-or flange w.

It-is also evident from the previous description, taken in connection with the drawings, that the bands being severed between the knotter and the grasper, and

while the grasper end of the band is inthe holdof the grasper, a short remnantof twine will .be' left in the grasper from the previously boundbundle. Asthese remnants or short ends accumulate in the grasper, they are forced outwardly therefrom by the new end of the-band caught, which new end is forced against the old end by the tongue is, as it is evident that when enough ends have accu- Y mulated to fill the grasper, one of these old ends will be displaced by theentrance of the s new. The new end ofthe band is pressed by the-tongue is against these remnants, and the security of the hold of the grasper thereby increased. As the knotter commences to revolve and at that time when slack is required in the grasper end of the band, with which to 7 wrap the hook, the knotter driving disk actuates thegrasper lever to open the grasper.

The cordis prevented from slipping laterally out of thegrasper-by the hook s on the stationary member'of the cord holder,'but the cord is free to slip or slide-through the grasper to give-slack for the wrapping of the hook. A sufficient amount of slack twine to wrap the hook maybe provided by this construction,

but it will be obvious that if no other means areprovided the band will have to be severed at a'sufficient distance from the grasper toward the knotter, to prevent the withdrawal of the cord from the grasper, as the cord is caused to slip through the grasper by the wrapping'of the-hook. 5 The guides, q and t, act to furnish a further'amount of slackto the knotter, and by thisemployment it is possible to sever the cord nearerthe grasperand consequentlyleave a shorter amount of cord in the latter. The guides q and t answer an addi- =tional purpose, as will be hereinafterdescribed.

' -attached to or formed integral with the sta- A curved guideqis attached-to the lever U, and an oppositely'disposed curved piece is tionary member-W of-the cord-holder. When the grasper is closed these two guides q and 25 make a V-shaped groove in which the cord running from the grasper lies, and by which it is the better guided into a proper position with reference to the knotter hook. These guides q and t also act to give slack to the knotter to wrap the hook, as will be now explained. The cam groove I is so formed thatit will, during the revolution of the disk, till the segmental rack thereon comes in mesh with the pinion Q, hold the grasper closedz' When, however, the knotter commences to revolve, the cam swings the tongue is backwardly in drawn back by such movement until it catches on the hook s, which prevents the cord from being withdrawn from between the lips to and w. The shoulder to on the tongue is car:

ries the cord, when the grasper is shut some-- what beyond the hook s; and as the-latter is somewhat nearer the knotten-a certain amount of slack is thereby provided. As,

however, the cord passesfrom between the lips or flanges m 1.0 up over; the guides q and t,

in the groove formed between'them'tothe knotter, when the knotter starts andthe lever=U- is swung away from the member W; the cord is free to slip downthe curvedsides of the guides t and q, and the bow or arch or.

knot in the cord provides more slack to wrap the hook. The amount of slack providedis determined by the size or height ofthe guides t and q. When a knife is used attached to the .swinging lever U, the knife may be formed as to constitute the guideqa The guide t may also be formed integral with the member-W of the cord-holder. The member W is secured to the breast-plate by means of a bolt passing through aslot in the holder W. By this construction the holder W may be adjusted with reference'to the lever U.

The knotter spindle is provided with a delay shoe S,-having the-delay"surfacesp"p"'. The delay surface 17' disk P-until the knotter pinion comes into engagem ent with the segmentalrack on the disk. The shape of the rim J isjillustratedin Fig. 10. The rim is cut away at a to permitthe revolution of the knotter hook. The pinion runs out of engagement with the rackatb and-the delay surface 19 rides subsequently on th e raised portion between 1) and c, in which position it is held by the stress of the outgoing sheaf, and

when in this'position the hookpoints-in-that direction most advantageous to the stripping rides on the rim J on i of the loop from the knotter. *Theraised part Y c then turns the hooks-in adirection-atright angles to the-slot-in the breast-plate,readyfor the result aimed atw Having now described my invention, what the succeeding bundle.
