GRAIN-BINDER.

Specification of Letters Patent. Patented June 20, 1916.

Application filed August 28, 1914. Serial No. 859,090.

'more particularly to a means for feeding the grain to the packing and binding mechanism, and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

The object of the invention is to providea mechanlsm for maintaining the grain in motion upon the deck of a binder so that it is .positively fed toward the packing devices, thereby preventing the grain from becoming improperly stacked up upon the deck in a more or less tangled condition.

It has for a further object to provide an auxiliary feeding device, adjacent the re-'- ceiving end of the deck of a grain binder, which serves to keep the grain in motion toward the packing devices and delivers the grain to said packing devices in the most effective condition for proper bundling and binding.

My invention also comprehends details of construction which, together with the features above specified, will be better understood by reference to the drawings, in which Figure 1 represents a side elevation of a portion of a grain binder embodying my invention; Fig. 2 represents diagrammatically a plan of the grain feeding and packing mechanism; Fig. 3 represents a detail of the packer operating connections.

1 designates a portion of the binder frame having secured thereto the extended side bars 2 which form supports for the deck 3 as well as other adjuncts of the mechanism. It will be noted that the frame 1 extends a suitable distance above the deck 3 for the purpose of forming a support for the breast frame 4:, which carries the knot-tying mechanism.

6 designates the cradle arm suitably mounted for oscillating movement upon the frame 2 and adapted to be driven by any suitable mechanism to correctly time its movements with respect to the packing and knotting operations, but as this mechanism forms no part of the present invention and has been described in my co-pending application, Serial No. 809,213, filed Dec. 29, 1913, I do not deem it necessary to here give a detailed description of the same.

7 designates suitable trip arms mounted in an operative manner upon the side bars 2 andforming a suitable movable frame for receiving the grain as it is fed along the deck and which also serves to cause actuation of certain automatic mechanism governing the needle arm 8, as will be readily understood.

9 designates the packers which pack the grain as it is received upon the trip frame 7 and cause it to be properly bundled against the cradle arm 6 ready for the binding and tying operations.

The packers 9 are pivoted at 10 respectively to the cranks 11 and each is preferably provided with suitable spurs 12 for the purpose of increasing the pressure of the grain upon the trip frame, and thereby positively insuring the actuation of the trip mechanism at the required time. Each of the packers, in the present instance, is pro; vided with an extension 13 connected to a separate cross head 14, the one being adapted to slide in the pivoted guide bar 15 at one side of the machine, while the other is similarly connected to a like guide bar at the opposite side of the machine, both of said bars being fixed to the rock shaft 16 which is journaled in the side bars 2 and operated by a suitable mechanism. The packer operating cranks 11 are mounted to rotate with the shaft 17 so that the packers receive a movement which passes them upwardly through the deck adjacent the receiving end of. the trip arm 7, then a movement toward the cradle arm 6 and finally a return move ment below the deck back to their original position. At the conclusion of the packing operation, the pivoted guides 15 are thrown downward to the dotted position which has the effect of maintaining the upper ends of the packers 9 from passing so far above the table. This latter movement is effected at the conclusion of the packing operation and removes the packers from their normal operation, the pivoted guides 15 are thrown free to carry the binding cord around the grain and to the knot-tying mechanism. The mechanism' for giving this desired movement to the packers consists, in the present instance, of a crank arm 18 suitably fixed to the rock shaft Y16 and pivotally conmounted to rock with said shaft which rock 7 isreceivedupo'n thedeckfrom'any suitable nected through a link 19 with one end of the pivoted rack arm 20, this latter being pivoted at 21 and having a locking shoulder 22 which is adapted to be engaged by the finger 23 of the connecting rod 24. The pivot pin 25 which connects the link 19 and the rack arm 20 carries the apertured head 26 of a stem 27, this latter being slidingly mounted in a fixed block 28 of the side bar 2, while between the saidblock and head 26 there is a compression spring 29 which serves to complete a toggle like connection of the parts 19 and 20 whereby the packer guides 15 are shifted at certain times to the dotted line position of Fig. 1, thereby lowering the packers to an inoperative position.

3O- designates a comparatively long link connected at one end to the wrist pin'8l of one of the cross heads 14, and at its oppositeendto a crank arm'82'fixed to therock shaft 83. This shaft extends transversely ofthe machine adjacent thereceiving end of the deck 3 and carries-a plurality of grain feeders 34, comprising radial pointed.

becomes stacked up at that point, thereby becoming tangled and massed-to such an extent that the packers are, unable'to properly engage andpack it toward thebinding por- 'tionof the machine, and consequently the bundled 'grain'is packed neither properly nor uniformly. my present invention 1 haveovercoine thisdifliculty since the grain upon leaving the "conveyers is not permitted to come to rest butis immediately carried forward out" of] the path of the following grain as rapidly as it is received, being .thus

source, such as the conveyers 35, whereupon the feeders'Si and packers 9 being in operation the grain is engaged by the former and advanced along the deck into the path of the packers. The action of the feeders 34 is to distribute the grain forwardly of the deck and prevent it from stacking up at the receiving end of the deck in a tangled condition. It will therefore be apparent by employing one or more of the feeding members and imparting a rocking oscillating or equivalent movement thereto, that the grain will be kept positively in motion upon the deck, with the'result that the packers receive the grain in the proper condition for easy and uniform binding. It will further be seen that when the packers are lowered below the deck during the operation of the needle arm, the connecting rod 30 will be-drawn in a direction to vary the This action does not change the length of the stroke of the feeders but shortens the stroke of that part of the feeders which is above the deck, and consequently the cut grain which is fed forwardwhile the needle arm is in its uppermost position is not distributed or fed as fast aS when the feeders are in their normal position. \Vhen the needle arm is in its uppermost position for binding'the grain, the feeders therefor move the grain along the deck against the rear portion of the needle arm so that by the time this latter drops to its lowermost position there will be a substantial sized bun- 'ated-as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I .do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from thespirit or scopeof the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is '1. In a grain hinder, the combination of a: frame, a deck for supporting the grain, a plurality of packers for packing the grain into binding position, a packer operating mechanism, a' rock shaft suitably mounted on said frame in fixed bearings, a plurality of feeder members fixed to said rock shaft and adapted to simultaneously move through and over said deck to engage and feed the grain to said packers, said feeder members stationary bearing secured adjacent to the deck and provldlng a fixed axls 1n which the arm is journaled, and means to oscillate 15 said arm whereby the grain is forced within reach of the packers and prevented from becoming stalled.

In testimony of which invention, I hereunto set my hand.
