'HARVES TER AND BINDER.

SPECIFICATION forming part of Letters Patent No. 757,128, dated April 12, 1904.

Application filed March 8, 1901. i

To all whom it may concern:

Be it known that I, EDWIN M. KnLLoee, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Harvesters and Binders, of which the following is a full and complete panying drawings, forming a part thereof.

The purposesiof this invention are, first, to provide a binder in which the usual alternating, oscillating, and reciprocating packers are omitted and in lieu thereof continuouslydriven devices are provided for accumulating and compacting the bundle; second, to provide new and simplified construction in which the resistance of the accumulated grain to the continuously-driven compacting devices operates to trip the binder into action; third, new and simplified construction by which starting of the binders action renders the continuously-driven devices for accumulating the grain inoperative through the bundle-space, While remaining still operative to clear the grain from the delivery side of the devices which forward the grain to the binder; fourth, simplified construction of the binder-train by which the same derives-driving power at the knotter end of the main binder-shaft and all mechanism at the opposite end is dispensed with except the crank and link for operating the needle rock-shaft; fifth, adapting a binder which derives its binding power at the knotter end of the main bindei shaft, as last above stated, toa harvester having an open-centerwhich deliver the grain through such wheel to the binder and specifically to provide a construction in which the binder shall be driven from a train at the grainward side of the tracthrough the Wheel above the path of the grain; sixth, to provide a binder construction in which the gate at the discharge side is positively latched during the accumulation and less, affords yielding resistance to the grain during such accumulation; seventh, to pro- V1de a construction 1I1'Wl110l1 the d1scharge- Serial No. 50,293. (No model.)

gate is unlatched by the knotter mechanism, 5 and specifically by means of the cord-holder of said mechanism. V

It consists, further, in features of construction relating to or growing out of the above features or their Figure 1 is a rear elevation of a portion of my improved harvester and binder, the platform and reel and some other parts being omitted and the traction-wheel being broken away at the rear part to disclose the mechanism interior thereto. Fig. 2 is atop plan view of substantially the same parts, the elevator mechanism being broken away at the right and the traction-wheel being cut away above 5 the horizontal plane of the axis of the main driving-pinion. Fig. 3 is a front elevation of the binder mechanism. Fig. 4 is a detail section at the line 4: 4 on Fig. 2. Fig. 5 is a detail plan of devices for locking the end gate 7 and unlocking the same by the action of the holder. Fig. 6 is adetail section at the line 6 6 on Fig. 3.

The harvester in connection with which my invention is shown comprises an open-cen ter traction-wheel A, having an interior driving-gear rim A a rigid main frame, comprising front and rear sills B B extending through the opencenter of the traction-wheel and supported and steadied on an interior tread-rim 30 A of the latter by means of suitably-located limbs B B B*, the power being communicated to the train from the interior driving-gear rim A through the pinion O, suitably journaled on one of the limbs of the frame, the train 5 extending from such pinion at the grainward side of the wheel to operate the usual cutting, reeling, and conveying devices, which are not attempted to be fully shown in the drawings, as the present invention does not concern their 9 specific construction. The details of the structure generally so far as it involves the extension of the rigid main frame through the opencenter traction-wheel and supporting and adjusting the frame within the wheel and transmitting power from the interior gear-rim thereof to shafts on the main frame are fully shown and described in my application, Serial proper combination, which 55 are set out in the claims.

' supported by the No. 7 O7 ,753, filed March 4, 1899, and will not be herein described in detail, but only referred to as may be necessary for a clear understanding of the features of the present invention. It is necessary to point out, however, that from the pinion C power is communicated to the train by means of a sprocket-wheel C, rigid with the pinion, around which a chain 0 passes to drive a sprocket-wheel C on a shaft 0 journaled in a bracket B of the main frame within the traction-wheel, said shaft extending grainward out of the wheel and driving the remainder of the train by means of a beveled gear 0 meshing with a beveled gear C on a fore-and-aft shaft 0 which at the forward end may have a crank to drive the sickle, while at the rear end it carries a sprocketwheel C, from which, by means of a chain 0 the lower elevator-apron K is driven. The bracket A at the front and A" at the rear obtaining ultimate support from the front and rear sills, respectively, gives bearing for the discharge-side roller of the upper elevatorapron. A sprocket-wheel C on the rear end of a fore-and-aft shaft 0 deflects the chain 0 and derives therefrom rotation in a reverse direction from the lower elevator-rollers, and said shaft 0 being extended forward carries at the forward end a sprocket-wheel C which by means of a chain drives the sprocket-wheel C on the forward end of a shaft 0", which is journaled in bracket-arms A and A, projecting up forward from the brackets A and A*, respectively. The purpose of this-shaft c, which extends fore and aft above the discharge side of the elevator, is to communicate power to the binder and to support and communicate movement to the means for carrying the grain thereto from the elevator, as hereinafter described. The upper element of the elevator consists of a short endless apron 70, carried around suitable upper and lower rollers is 70 This upper apron has its discharge-side roller located at a considerable distance backthat is'to say, grainward-from the discharge-side roller of thelower apron K, so that the shaft 0" and the mechanism thereon located above the discharge side of the lower apron operate at a position stubbleward from the discharge side of the upper apron, as particularly seen in Fig. 1.

D is the'binder standard or frame. It is main frame-sills B and B fore-and-aft tubular bars B and B being connected rigidly to the portion of said sills which extends stubbleward from the traction-wheel,

and the lower arm D of the binder-standard having the lugs D D, by which said standard is seated and adapted to slide fore and aft on said tubular bars in the adjustment necessary to accommodate the varying lengths of the grain. Any suitable means may be provided for sliding the binder at will, as the rock-shaft D, journaled in the bracket arms or lugs D D, projecting rearward past the said rim of the traction-wheel, such rockshaft having at the grainward end the leverarm D for operating it and at the stubbleward end a crank-arm D connected by a link D to the lug D of the binder-frame standard. The lower fore-and-aft arm D of the binder-standard D constitutes a bearing for the needle rock-shaft e, on which E is the needle at the rear end of said bearing and E the crank at the forward end.

D is the upper fore-and-aft arm of the binder-standard, constituting the hearing for the main binder-shaftf, which extends therethrough, having at the forward end the needle-operating crank F and at the rear end of the bearing, first, next to the end of the bearing, a crank F for a purpose hereinafter explained; next, the loose sprocket-wheel Gr, whose hubg at the farther side from the hearing has the teeth gy for engaging the clutch-dog, (see Fig. 4;) next, the knotteroperating wheel F, on which at g, at the side toward the wheel G, is pivoted the clutchdog Gr, provided with a spring g, tending to throw its abutment g into engagement with the loose wheel G, and, next, outside the knotter-operating wheel, the knotter frame or hanger H, beyond which at the end of the shaft is fast thereon the outside discharger f, whose hub f constitutes a collar to retain the shaft.

H is the breastplate, extending rigidly from the lower end of said knotter-frame and having a further extension H, which reaches grainward through the open center of the traction-wheel and carries at f 1.1 a sprocketwheel (1*, which is feathered and adapted to slide on and be continuously rotated by the shaft 0, located, as above described, above the elevator at the grainward side of the traction-wheel. The grainward end of this breastplate extension 'H is directly supported on the main frame of the harvester, a tubular fore-and-aft bar A being provided, supported by the bracket arms A and A 9, and the grainward end of said breastplate extension lgaving slide-bearings H H on said tubular M is a chain driven by the sprocket-wheel G and driving the sprocket-wheel G, which is thereby continuously driven. The chain M has suitably pivoted to its links at convenient intervals teeth or fingers M M, &c., which are designed to take the grain directly from the elevator and advance it stubbleward through the binder.

N is a lever pivoted at h near the bearing of the wheel C and extending thence stubbleward along the course of the chain M above the breastplate and having toward the stubbleward end an open cam N, which encompasses the main binder-shaft f immediately rearward of the end of the bearing, and thus encompassing a crank F fast on the shaft f adjacent to the rear end of the bearing, as

, set'therefrom so as to extend on the opposite side of the wheel G from the cam N, said arm constituting a tripper for operating the clutch-dog G, which is pivoted to the back of I the knotter-operating wheel F and provided witha stud and roll abutment G adapted to engage any one of the teeth g of the hub of the wheel G, and thereby cause said wheel to ;,be engaged with and rotate the shaft f. The nose G of the clutch-dog when its abutment G is thus engaged stands in position to encounter the end of the tripper N when the latter is in'normal position, as hereinafter explained,and the dog is thereby disengaged from the wheel G, bringing the binder to rest at the conclusion of its binding action. Thiifteeth or fingers M of the chain M are providedwith tails M M, &c., which trail on the lever N, and said lever when in nominal position (at which the tripper is engaged with he clutch-dog and holds the same out of engagement with the wheel G) thus operatesto hold the fingers protruded in position toeiigageand actuate the grain. A spring reacting between the lever N and the support t" vhich it is pivoted, tends to hold it When thus held, the chain iiithis osition. being con'tinuously driven, engages the grain byfgmea nsi of the fingers M, taking it from thedelivery of the elevator'and advancing it into ,theibinder, compacting it against the dischargagate,hereinafter described,until the. resist'ancetof the grain thus compacted operatingagainst the fingers M forces them back, causifigtheir tails M to crowd against the lever N and swing it about its pivot until the tripper N is disengaged from the clutch-dog G, which thereupon becomes immediately engaged with the wheel G, causing the shaft f to be rotated. The first movement of the shaft causes the wrist of the crank F operating against the straight face a of the open cam N, to force the lever back still farther than it has been forced by the mere pressure of the grain on the fingers, thus not only carrying the tripper quite out of the path of the clutch-dog, but also permitting the fingers to be folded back in inoperative position throughout the bundle-space, although they are held protruded in operative position at that portion of their path at which they pass around the wheel C and take the grain delivered from the elevator, a shoe or track T for that purpose being secured to an arm H which projects from the breastplate extension H This track the tails l encounter as the chain passes onto the wheel (3, and said tails ride thereon until they pass onto the lever N near its pivot. The grain is thus conthe binder into action consists of the devices for advancing the grain into the binder, said devices being so constructed and operated that the resistance which the grain, advanced and compacted by said devices, offers to the compacting and advancing action causes delay of the advancing devices involving movement of said devices relatively to parts which are not delayed, such relative movement be ing taken advantage of to operate the tripping devices. This action originating, with the resistance offered by the grain to the movement of parts tending to impel it should be distinguished from action which might be produced by pushing the grain against a yielding resistance, since in the latter case not the resistance of the grain, but its incapacity to further resist, and its consequent movement under pressure, would produce the tripping action, and this distinction is to be undertood as involved in the use of the term resistance of the grain, as employed throughout this specification and my claims in this application.

When the binding operation is completed and the bundle is discharged and the needle recedes, the tripper is restored to position for disengaging the clutch-dog by the rotation of the crank F which, having made a full halfrevolution from the starting-point, begins to engage the cam l" as it starts on the second half of its revolution and positively forces the lever N back to initial position, where the tripper encounters the tail of the clutch-dog and disengages it from the wheel Grand positively stops the rotation of the knotteroperating wheel to which the dog is pivoted.

In order that the grain may be packed against a yielding resistance while the bundle is being accumulated, as is desirable for reasons well understood, and at the same time may be positively restrained in the bundle-space until the full quantity for a bundle is accumulated, I provide a deeply-- recessed discharge-gate P, which is hinged to the frame at the needle rock-shaft side of the bundle-space and adapt it to swing in to the breastplate at the opposite side, where it is provided with a latch or automatic catch P, with which it becomes engaged when it is thus closed. To this gate there is connected a yielding member P hinged at the inner side of the gatethat is, toward the advancing grain extending across the deep recess of the gate and provided with a spring tending to hold it swung in toward the grain to a limit determined by a suitable stop 19 on the gate.

, This member is thus adapted to yield stubbleward as the grain is packed against it during the accumulation of the bundle. In order to unlatch the gate and 'allow it to be swung outward for the discharge of the bundle, I provide upon the cord-holder S of the knotter mechanism a projection S in such position as to encounter the tail p of the latch P a little before the holder comes to rest at the proper time for the opening of the gate and the discharge of the bundle. The gate being under pressure of the grain at this stage will fly open the moment the catch is released, and the holder completing its movement runs off the tail of the catch, and it is by its spring restored to its position to again engage the gate when the latter is picked up by the tail of the needle encountering the back side of the gate at P as the needle recedes to its position of rest.

The spring M may be adjusted to vary its tension, and thus vary the limit of pressure necessary to trip the binder and regulate thereby the size of the bundle. Such adjustment is provided for by forming about the pivot it of the lever N a flange it, having a plurality of pins it, against any one of which the end of the spring may be secured, thus coiling it more or less tightly.
