v To all whom may concern; j

- Be it known thatI, ED'V RD W. Jnnnrns,

citizen of the United Statesfand resident of Norrlstown, county of 7 Montgomery, and State of Pennsylvania, have invented an Improvement in Grain-Binders, of which the following is a speclficatl'on.

The object of my intention is to provide an organized apparatus for satisfactorily packing and bindlng gra n into a bundle,

and the present improvementsare more particularly directed, among other features,to themeans for insuring'the proper density of the bundle at the't'im'eof binding the same With the cord, and for insuring the act of binding and the tyingof a'knot auto mati cally under the control of pressure of the grain which is being packed' to constitute the bundle.

My object is also to provide a cradle arm against Which the grain is packedby'the packers in the formation ofthe bundle, the

said cradle arm being adjustable" in such manner thatit may also act asa direct support for the knot-tying mechanism, so that the latter, together With its'carrying means, is supported against the actionof the needle arm during the process of tying the knot, 'Whereby undue' yvear and looseness of the support ng parts of the knot-tier are 'pre:

vented, and Whatever ear should occur may be taken up by the adjustable means constituting in part the cradle arm; said cradle arm being so arranged as to' directly receive the thrust of the overhanging knotterand its support and transfer it to themainpart of the binder frame at a lower elevation.

My object is also to provide special im pi'ovelnents for operating the needle arm' whereby it is positively reciprocated tobind; the/bundle and then brought to rest,the said": movements being accomplished by a floating gear engaging a return rack upon the'binden arm'andpositively maintained in geared re} lation thereto during the bindingoperation My object is further to provide -means for operating the packers whereby they may be suitably thrown up into operating packing position, or down out of packing action at the 'prop'er times, the said actionsbeing governed by the same means Which-operates and controls the timeof action "or the binder arm;

and further, by the employment ofdischarg ing devices or kickers Whichare brought into action by the combined operation of: theneefl dle arm and the means employed for operatframe;

v 32 designates alink pivotedto the rod 30 at'one'end and at itsiopposite end to an arm 33 which is pivoted at 34 to a suitable part of the frame 1. The saidarm 33 ispreferably provided with an eyelet 35 to receive h the ang'ularly disposed end 36 of a torsion 'sprmg 37 which is suitably secured to the frame '1 and has its opposite end 38 fixed in a lug 39, of the said framel. The spring 37 is normally under vtension to move the arm 33. andvlink' 32 in the direction of the arrow A so that when the catch mechanism 29 is released the parts controlled by the said 'spring 37 will be automatically actuated to produce certain movements in the cycle of operation. In connection with the link 32- it will be noted that the same is provided I with a lug 40 the function of which will later appear. v

As the grain is received upon the trip arms 12 it is subjected to the action of the packers 41 which feed it into position againstthe cradle arm 42 so that the proper size bundle is automatically made upi'r'or the bindingand tying operations. The packetrs 41 are pivoted respectively at 43 to the cranks 4 and eachis provided with suitable I spursor projections 43 -and with'an extension44 carrying a cross head 45 which head slides in the pivoted guide bars 46, the latter members being fixed to the rock shaft 47 The spurs or projections of the packers serve to impart an extra pressure upon the grain to assist in the actuation of the trip mechanism of the arms 12, thus insuring the operation of the binding mechanism when the proper quantity (of grain has been formed into a bundle. I

The cradle arm 42 is movably mounted upon a pin 48 having a bell crank member49 keyed thereto, one end of which terminates in a threadedhead 50 for receiving the bolt 51. This bolt 51 passesthrough an apertured ear; 52 upon the cradle arm 42," thus aiiording ameansifor adjusting and varying the relation lofthe cradle arm to thebifurcated end of the breast plate 9 with which latter the cradle arm is adapted to engage during thelpacking and knot-tying operations in order to steadythe free end of the breast plate, take up the thrust of the parts and prevent undue wear. The opposite end which in turn is journaled in the sidebars 2.

of the bell crank 49 carries a roller 53 shifting the cam plate 54 so that the roller 53 is no longer fixed and consequently the cradle arm 42 is free to swing gravity away from the breast plate 9 to permit the bundle to be removed or ejected from the machine. I a

At the conclusion ofthe packing operation it is essential that the packers be shifted to allow, the needlearm to carry the binding cord around the grain and to the knot tylngmecha'nism, and for this purpose I have provided a mechanism for shifting the packer guidearms 46 from their normal operative position to that shown in dotted stance of a crank arm 59 suitably fixed tothe rock shaft 47 and 'pivotally connected through a link 60 to a'rack arm 61 having a suitable rack 62 formed thereon. The arm 61' is mounted for swinging movement upon the pin i8 and is providedwith a locking shoulder 63 whichis adapted'to be engaged by a finger 64 of the connecting rod65. The pivot 66 which connects the link 60 and rack arm 61 carries the apertured head 67 of a stem 68 which is slidingly mounted in a fixed abutment or block 69' of the side bar 2, and between the said'block and head 67 thereis a compression spring 70"which acts to break the toggle-like connection of the parts 60 and 61 at certain times to cause the packer guides to shift quickly to theqposition' where the packersare inoperative. The'rackf62 is operated in the present instance by means ofa pinion 71 keyed to the crank shaft 3 and movable with the lever arm 58, it being understood that the said pinion and rack are normally out of mesh but'arethrown automatic. releasing V v 1 to depress thetriparms 12 against the action into engagement by the of the lever arm 81. i V '72 designates thejn'eedle arm which is preferably formed integral with a rack disk 7 3 swingingly mounted upon-the spindle 48, r the said disk being suitably cut away to form an internal-cam shaped rack 74'wl1ich is continuous except fora small portion of its length as shown at 75, this part being between the beginning and end of the needle arm stroke. It will therefore be apparent, owing to the fact that the pinion is rotating ,in substantially fixed relation to its'adjuncts, that as soon as itJcomesinto mesh with the rack'74c, it will cause the needle arm disk 7 3 to swing about its ,pivot48 andthus cause proper oscillation of the needle arm 72. In order to prevent the disk 73 dropping away from the pinion 71, at theend of the up-stroke of the needle arm, I have provided a cam roller 7 6 carried by the lever 58 and so positioned as to contact with the bottom portion of a cam 77 fixed to the disk 73 adjacent the part thereof corresponding.

to the end of the up-stroke of the, needle arm 7 2, as will be understood. The pinion is thus effectually maintained in mesh with the raok-74 throughout its length and Zincparts a proper oscillating movement thereto to give the needle arm a movement timed with its adjuncts. This movement of the rack disk 73 I have utilized as a means for transmitting movement tothe kicking mechanism for ejecting the bundle of grain from the machine after the knotting operation, and the mechanism for carrying outthis step comprisesthe connecting rod which is pivoted at 78to a suitable part of the said I disk and has its opposite end connected by a link 7 9 to the lever arm 58 andthrough this link '19 I have passedthe transverse bar 80 which carries the upwardly extending kicker members 81 which terminate" adjacent the grain bundle in its cradle. I

82 designates a'cam abutment formed on the outer face of the needle arm in order to contact with the lug 40 at a certain time in the travel of the needle arm,- and 83 designates a roller carried by the disk 7 3 for the purpose of engaging the arm 33 for a purpose which will be later described.

The operation of the device is as follows; I Withthe parts positioned as shown in Fig.-

1, and with the crank shaft rotating, the

'mechanism is ready to receive the grain for binding purposes and the several steps in the operation take place as follows: The grain is automatically fed to themachine and is received upon the arms 12 which are norm ally held above the deck, where the grain .is in position to be carried forward and packed against the arm 42 bythe action of the packers 41 which are continually operating adjacent the arms 12. lVhena bundle of:;grain of sufficient size has been "placed in position, the pressurethereof is sufficient of thespjring 15 with the result that the latch member '28 is thrown to the right. as shown in Fig. 3, thus releasing the lever arm 31'and its adjuncts. The moment this lever 1 and its parts. As soon as the pinion meshes with the rack 62 movement is transmitted to the latter and it swings upon its pivot-a8, until a POSltlOIl lS reached where the action of the spring 70 is sufiicient to give a quick downward throw to the link 60' and thus rock the shaft Q? to bring the packer guides 46 to the position indicated in dottedlines in Fig. T1, which action removes the packers from the field of the bundle. Attention is directedto the fact that when the lever arm 31 is shifted as above described the long arm 58 ofthe' same lever is of course moved co'rrespondingly,- thereby'swinging the coin necting rod 65 so that the locking finger 6% is removed from the path of th rack lever 61. As the pinion 71 runs out of mesh with thevrack 62 the spring 15 again'shifts the lever armSl so that the pinion '71 now engages the rack 74 of the needle arnn thereby starting the needle on its forward, upg ward stroke. This movement of the needle is a continuous one,-1alnd the pinion 71 rides one side of the rack; then as the roller 76 engages the cam 77, thesaid-pinion passes the action of the needle, which then returns to its normal inoperative'position as the 'knot-tying operation has now been completed,-lit of course. being understood that the knot-tying mechanism is automatically actuated to tie 'thexknot at the proper time kickers 81;

in'the cycle of operation; At the time the needle arm is approximately at the end of 7 its rip-stroke, the roller 83 comes into posi tion to be engaged bythe end of the spring pressed arm 33, which 1s the position shown 111 F 1g. 5.

lineof the applied force so that there is no chance for the said arm to turn upon the downwardly and assumes the osition shown in Fig. 6. In thispositionthe lug projectsinto the path of movement of the cam surface .82 and consequently as the needle makes its return stroke its cam 82 forces the link 32 and arm 33 to the right as shown in Fig. 6 until such time asthe pivotal point between the link 32and lever arm 31 18 above the end pivot of the arm 33. lVheIl this takes place the spring action causesthe link32and connected lever 31 to snap back to'the normal position shown in Fig.1 and there be automatically lockedby the action ofhthe spring pressed cap 28. During the movement of the lever arm 31 to the'posi- .tion shown in Fig. 6, it is adapted to strike or contact with the trip 57 thereby moving the cam member 54: upwardly as shown in Fig. 8 and releasing the cradle arm 12 so that it may drop'by gravity away from the breast plate 9 and thus permit the bound bundle to be ejected from the machine by the automatically actuated ejector arms or he rack arm 61 whlch has been instrumental in shifting the packers out of operativeposition isreturned to its normal position by the action of the finger 641 which has, during the movement of the rack plat-e 73, been shifted again beneath the lug 63 so that as the said plate returns to its normal position it causes the rack arm 61 to be tilted back to its former position ready for engagement. withthe pinion 71 upon the next binding operation.

It will now be apparent that I have devised a'complete unitary structure wherein the packing and binding of grain into a bundleare carried out in asatisfactory and efficient manner producing a bundle of proper density and one which is securely heldby the knotted binding cord. It will furtherbe apparent that I have provided in the cradle arm. structure ,a means which is adapted to coact with the breast plate In this osition ofthe parts the pivotal points of the arm 33 are inthe directof the, knot-tying mechanism so that the lat dle arm and results in a material reduction of the wear of the moving parts. Furthermore, it will benoted in this connection that the aforesaidcradle arm may be readily adjusted to take up any wear which may occur and thus always be maintained certain times in bracing engagement with the breast plate. Ihis adjustment is effected through the me hum of either the adjusting bolt 51. or the adjustably mounted cam locking member 54. It will further be apparent that I have provided in the floating pinion and its encircling'needle arm rack a positive means for controllingthe actuation of the needle arnrfor either stroke thereof and thus insuring the correct timing of the needle arm with respect to the mechanism which is dependent upon the; said needlearm for bindingand tyingthe knot in the binding cord. It will further be apparent that I havedevised an exceedingly effective packing mechanism which is controlled by an automatic mechanism serving to vary the position of the-packers according to the particular operation in action and thesaidi packers are therefore automatically moved first to. aposition to pack the into a suitable bundle and then automatically thrown to aposition where they become inoperative asfar asthe grain is concerned, and removed from the vicinity of the needle arm and the knot tying mechanism during the binding and tying of the grain.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the in.- vention and the above description, and while Ihave in the present instance shown and grain described the preferredembodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same issusceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
