:GXRAIN-BINDERJ SPECIFICATION forming part of Letters Patent No. 654,833, dated July 31, 1906.

Application filed July 20,1898.

To aZZ whom it may concern.-

Be it known that I, EDWARD WJENKINS, of Norristown, Montgomery county, Pennsylvania, have invented an Improvement in Grain-Binders, of which the following is a specification.

My invention has reference to grain-bind ers; and it consists of certain improvements 1 which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide an automatic packing, binding, anddisoharging mechanism suitable for harvesting-machines.

In carrying out my invention I provide a suitable table over which the grain is fed and upon which it is packed by suitable packingfingers having a rotary reciprocating motion at their free ends and adapted to pack the grain in a cradle formed by a rear retainingarm which under the proper pressure of the" bundle automatically falls away and liberates the bundle, the said movement being controlled by the action of the needle-arm, which is thrown into operation automatically after the bundle is suitably packed and attains its requisite size and firmness. My improved needle-arm is operated by means of a pinion and curved rack, the said parts being so arranged that when thrown into mesh the pinion operates with a curved rack at one side of said pinion to forcethe needle'outward and around the bundle, and in continuing to mesh with the rack on the opposite side of the pinion the reverse operation is brought into play and the needle-arm isreturned. This operation is accomplishedby imparting a relative lateral movement between the pinion and the rack, the same being secured by the action ofthe packers in their operation upon the bundle. These packers are prevented from moving the pinion until a definite pressure is secured, at which time the tendency to movement overcomes a resistinga stop adapted to hold the pinion ina position out of gear with the rack of the needle-arm. Any other suitable means to operate the needle-arm fro nth'e shaft in place of the pinion and racks may be used, if desired. The operation of the needle-arm is also such that through suitable mechanism it causes the trip better understood by reference to Serial No. 686,402. (No model.)

which sustains the cradle-arm to be thrown out of position,and thereby permit the bundle to force its way from the cradle and be dis= charged under the action of suitable kickers. The kickers are fingers which are brought forward below the table and their free ends then raised and moved backward in line with the bundle, so as to cause it to be bodily discharged. These kickers are directly operated by the needle-arm. They are movably connected and arranged to reciprocate in planes substantially parallel to the needle-arm and adapted to move across the axis of oscillation thereof, whereby the said free and unobstructed movement close to the needle-arm and above and below its axis of oscillation.

Another portion of my invention relates to the means of operating the knotter. I arrange a stationary'knotter above the bundle and stud, said block being connected in any suitable manner witha movable part of the knotter; As the needle-arm moves over the block the stud thereof is received in a recess on the needle-head, and the continuous movement thereof causes the block to rise from the looking position until liberated and then be carried forward with the needle-head, and thus secure a positive motion to the knotter. In the reverse operation the backward motion of the needle-head brings the block to a position where it may again fall into its locking-recess and permit the needle-head to move on. Under this operation the knotter is again set and the machine is ready for future operation. This part of my improvement comprehends, broadly, the operating of a knotter independent of the needle-arm by the movements of the needle-arm.

kickers may have provide a reciprocating block having a tails of construction in addition to the gen eral features herein pointed out andwill be panying drawings, in which Figure 1 is an end elevati V proved grain binder with small portions broken away. Fig. 2 isa plan view of the operating mechanism and with the knotter and its holder removed. Fig. 3 is a plan view the accomon of myjimzoo of the knotter and its holder-frame which have been removed from the machine, as 1 pointed out with reference to Fig. 2. Fig. 4: is a sideelevation of the needle-head. Fig. 5 is an elevation of one of the packers, and Fig. 6 is a diagram illustrating the kicker mechanism for discharging the bundles.

. A represents the elevating devices of the harvestingmachine and may be of any suitable construction. They discharge the cut grain upon the upper end of the inclined table B. Pivoted at O on a fixed frame H, arranged immediately under the table, is the needle-arm D. Thisneedle-arm is fully illus tratedin Figs. 1 and 4. It isprovided with a head (1, having an oblique notch or slot'd for operating the knotter, as hereinafter described. The pivot-bearing of the needle-arm is very short, so as to permit the free passage of the kickers or discharging-arms over its ends and parallel to the needle-arm. The body portion of the needle is provided with a curved slotted portion concentric with the axis of rotation O and having its opposite sides and the rear end provided with teeth constituting a U -shaped rack. The pinion D is adapted to mesh with this rack and is secured'to the end of a driving-shaft J. The driving-shaft J maybe rotated in any suitable manner from ,the"-fixed part of the machine and terminates in two cranks L L, arranged at one hundred and eighty degrees apart and provided with the pinion D interposed between the said cranks. The end of this shaft J, adjacent to the cranks, is journaled in a movable frame J, which is pivoted to the fixed or stationary frame H at T. This frame permits the pinion to be moved over into mesh with one end of the rack D under the action of the packed bundle, but normally is held out of such contact by means of a shoulder or arm J carried on the end of the torsional spring J whose spring action is adjusted by a suit-able adjusting device J The locking-armJ may 1 also be provided with an arm or finger J exat or near their middle portions to the two ing tending up into the path of the packed grain, so as to be acted on thereby and assist at the proper time in liberating the frame J.

K K are two packers respectively pivoted cranks L, and their rear ends are connected bylinks it with the fixed frame H. The operation of these packers is such that the pack ends are caused to describe ovals and force down the grain into the cradle until it is sufficiently packed or compressed to create a pressure against the said packers capable of pressing the shaft J rearwardly and forcing the arm J from under the action of the shoul der of arm J When this is done, the pinion D?, which is constantly rotating,causes the needle to rise and-pass over into a position above the knotter E. The continued operation ofthe pinion then returns the needle by the pinion meshing with the rack opposite, tothat with which it first engaged. If de-,

sired, this tripping action may be facilitated and made to be more positive by extending the arm J as indicated at J so that its rear.

end projects above the tableA w thin the cradle and adapted to be directly pressed upon by the grain being packed. It will be evident that broadly considered it is only essential to myinvention that there shall be a.

relati-vemoveme'nt between the rack portion of the needle and the pinion, so as to insure the proper, engagement and disengagement. I would remark here that as soon as the bundle has been discharged the pinion and its supporting-arm J readjust themselves and the parts again and assume the locked position indicated in Fig. '1 automatically.

F is a fixed frame forming the upper part of the cradle and is connected to the tubular frame G at F and also at the extreme up per end to the main frame of the harvestingmachine at F The lower end of the frame F is free and contains the knotter E, of any suitable construction. This knotter is adapted to rock and is provided with an operatingblock E, having an oblique pin 6 on its upper end. When the needle-arm is in the po= sition shown in Fig. 1, the block is seated in the recess in the upper part of the overhanging frame F and is'held against movement by a shoulder F thereof. When the needle advances, the pin 6 is received in the oblique slot 01 on the head D of the needle, and this causes the block to rise to make a connection with the needle-head and then be drawn forward to the position indicated indotted lines in Fig. 1.- The result of this is to rock orreciprocate the knotter. When the needle-arm returns, the block is pushed backward and automatically drops again into the recess F, and the needle-head goes backward without further connection with the knotter. It is immaterial tomy invention what the particular means for insuringthis' automatic connection of the needle-head with the knotter may be. Y

I is the cradle arm and is pivoted on the shaft 0 concentric with the pivot of the needlearm. This arm is curved, as indicated, and its free end 11 is adapted to'fit into the end of the overhanging arm F, so as to steady the V knotter when under the action of the needlehead. The near end of the armI is provided with a projection I, which normally rests against theend of a locking-pawl Jflpivoted to the main frame at J This holds the arm I up against the pressure put upon it by the packed grain, and the pawl J' is maintained in such locking'position by the projection c of the needle-arm. When, however, the needle-arm has been raised fully about the bune dle, the shoulder a on the needle-arm adjacent to its pivot strikes the pawl J and draws it to one side, so as to quickly liberate the cradle-arm land permit it tofall out'of the way by gravity and the forward pressure imparted to the bundle. When, however, the needlearm returns to its lowermost position, it pressesupon the pawl J and the pawl in turn presses upon the projection I, so as to force up the cradle-arm I again into a position to constitute the cradle, as indicated in Fig. 1. It will thus be seen that the operations of the various parts are purely automatic. It is evident that the arm I need not extend into contact with the rear end of the frame F, as indicated at 11, but it is preferable to form this connection so as to steady the knotter and to resist any springing action during the knotting operation when the needle-arm has been driven forward.

As the grain is forced into the cradle under the action of the two alternately-operating packers K K it is caused to advance in front of the teeth or clawsf", respectively arranged upon the adjacent sides of the frame F of the table 13. In this manner the grain may freely pass into the cradle, but its backward movement is resisted.

M represents kickers or discharging-arms. They are pivoted at one end to a bell-crank lever M, jointed or hinged to the lower end of the frame J. The other end of the bell-crank lever M is formed with a claw adapted to make a locking connection with the frame H, as at M this connection being positive when in the act of discharging the bundle and upon the return movement of the needle-arm. The kickers M are furthermore jointed to the needle-arm D by connecting-links m, the said links being pivoted to the needle-arm near the rear end and at a distance from its center of rotation, and at the opposite ends said links m are hinged to the kickers intermediate of its two ends, as clearly shown in Fig. l. The operation of this kicker is such that when the needle-arm is being forced forward in the act of binding the link on pulls the kicker forward, and as at this time the pinion and its frame J are moved to the right the bell-crank lever M will be free at the point M Under this condition the kicker is driven downward and under the table to a position such that its free end passes above the bundle and upward. As the pinion D follows'the rack at the righthand end of the needle-arm the frame J is swung upward and locks the bell-crank lever M at the point M on the stationary frame H Now upon the return movement of the needle-arm the kicker-arms M are positively thrown backward, moving about the pivotpoint M as a ing the upper fixed center, and thereby causor' free end of the kickers to press positively upon the bundle and discharge it downward and outward, the cradlearm I having previously dropped out of position. In doing this the kickers pass across the pivot-axis of the needle-arm. As soon as the needle-arm commences to rise the links m begin the forward motion and drag forward the kickers M. To prevent, however, too great movement of the kickers M toward the links m, I provide stops 8, which limit the relative horizontal movement of these two parts, so that as soon as they become locked the pivot-point m of the bell-crank lever is caused to descend and swing said bell-crank lever to accommodate itself to the backward Ihave illustrated my improvements'as I prefer to actually construct them in practice; but it is to be understood that equivalent constructions may readily be substituted for those here shown. Hence I do not limit myself to the minor details, since it is apparent that they might be modified in various Ways without departing from the essential principles of my invention.
