Application filed July 23, 1887. Serial No. 245.055. (No model.)

To all whom it may concern.-

Be it known that I, LAVERNE \V. NOYIJS, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Self Binding Harvesters, which are described and fully set forth in the following specification, reference being had to the accompanying drawings, forming part thereof, wherein- Figure 1 is a plan. Fig. 2 is a rear elevation. Fig. 3 is a detail rear elevation of the discharging mechanism in the process of ejecting the bundle through the trap-gate. Fig. 4 is a detail elevation of some of the same parts shown in Fig. 3, the position being that at which the discharger is being tripped into operative position. Fig. 5 is a detail elevation of the compressor and connected and operating mechanism, the position being that just preceding the instant of greatest compression. Fig. (5 is a detail elevation of the same parts shown in Fig. 5, the position being that at which the discharger is tripping the clutch-dog to disengage the compressor from the needle rock-shaft. Fig. 7 is a detail elevation of the same parts at the instant the compressor is falling out of the path of the bundle to allow its discharge. Figs. 8 and 9 are details of the locking dog in positions corresponding to those of Figs. 5 and 6. Fig. 10 is an inner side elevation of parts on the binder-mechanism driving-shaft, principally designed to show the manner of securing the dischargercams. Fig. 11 is a section through mm, Fig. 7. Fig. 12 is asectioual elevation of the compressor and frame, the section being at the line y g on Fig. 7. Fig. 13 is a detail elevation of a modification of the bundle-receiving trapgate. Fig. 14 is an elevation of the compressorframe detached from binder-frame. Fig. 15 is a plan ofthe extensible compressor link comprisingits springand a housing which forms a stop for one end of it.

The construction of the general frame-work of the machine,tbe devices for raising and lowering and tilting and the gearing for commnnicating the driving-power to the conveyer and binder, although in part appearing in the drawings, constitute no part of this invention and willbc referred to only in so far as maybe neces sary or convenient in describing the location of those parts with which the invention to be claimed is directly concerned. In general it may be stated that the frame which crrries the platform and sickle and conveyer is the same as that which carries the binder, and may be made adjustable as to elevation and inclination or tilt in any well-known way. Parts of this frame not otherwise specifically mentioned or lettered, wherever appearing in the drawings,arc lettered A. Specific parts having relation to this invention and rigid with said frame as a part or adjunct thereof are indicated by the letter A with an exponent, ex

cept the binder-frame proper, which,althoug l1 it may be rigid with the platform-frame, 1s treated as an independent structure, and with its parts and rigid adjuncts is denoted by the letter B and B with an exponent.

The conveying and packing mechanisms are denoted by the letter 0, applied to all parts thereof not specifically described, and all spe cific parts are indicated by the letter C with an exponent.

The several parts of the binder mechanism are specifically lettered as hereinafter indicated.

D is the drive-wheel, which communicates power in the usual manner to the drivingtrain, of which the first wheel visible in the drawings is the beveled gear-wheel E, which is clutched to the shaft of the main drivingpinion, which shaft is journaled in the gearing-bracket A on the platform-frame. Said gear-wheel E drives the beveled gear-wheel E, whose shaft 0 isjournaled suitably on the plat form-frame, and has the spur-gear E", which meshes with the gear-wheel G on the cranked shaft 0, which is also journaled on the platform-frame, and by means of its double cranks c c actuates the reciprocating feed-bars G, whichconstitute part of the conveying mechanism of the platformconveyer. .A similarlycranked shaft, 0 at the grain end of the platform is rotated by the feedbars 0', part of the cranks 0 being ninety degrees from the remainder, so that there is no dead-center. At the forward end of the shaft 0 there is fixed a roller which drives the endless belt 0 which at the grain end passes around the roller 0 which may be either loose or fast on the shaft o but is preferably loose, since it may be desirable to give the belt a greater or less speed than the feed-bars G which may be done by making the driving-roller on the shaft 0 larger or smaller, which would necessitate a loose roller on the shaft 0. At the stubble end the feed-bars C are provided with inclined extensions G which protrude through the binder deck approach and operate as packers. The intervals between the bars 0 in the platform are filled with strips of fixed floor; or, in other words, the feed-bars operate through slots in the platform in the usual manner of such conveying devices.

The binder-driving mechanism, including the tripping and clutching devices, may be of any well-known construction. They are not shown in detail. The main binder gear-wheel F, however, isdriven by atrain deriving power in any manner from the shaft 0, and the nee dle rock-shaft R is actuated in the customary manner by a link, ll, from the wrist-pin f on said gear-wheel to a crank-arm, R on said rock-shaft.

The peculiarities of this invention are found in the dischargers and their operating mechanism, the compressor and its operating mechanism, and especially in the relation of both said elements to the form of the deck and breast plate, and to a certain auxiliary-via, the trap-gate K-which will be hereinafter specifically described.

The shaft fof the binder gear-wheel F is journaled in the arm 13 of the binder-frame, and near its rear end it carries the knotteractuating cam-wheel F, having the usual functions and position. Adjacent to said camwheel the knotter-frame is hung on said shaft, as is usual, and is extended grainward and obtains further support on the arm 13 of the binder-frame, which is extended horizontally rearward from the binder-gear standard B. From the knotter-frame are extended arms which terminate in the discharger-controlling cams G Gr, which are pierced for the shaft f and are situated about said shaft, one forward of the knotter-frame and the other rearward of the lmotter-aetuating cam-wheel, and adjacent to them, respectively, are the dischargeractuating arms G G, which are so secured on said shaft f as to be revolved thereby, the forward one in'front of its cam and the rear one rearward of its cam, and to the ends of said arms (ir are hinged the dischargers proper, G G, though, functionally considered, the two parts G and G together make up a folding or collapsing discharger.

The dischargers G have an arm, G setting off from near the pivot at nearly a right angle to the direction of the bundle-actuating arm, and said arm G has an abutment in the form of an anti-friction roll, 9 which engages and travels upon the periphery of the cam G, and while passing over the concentric part 9 of the cam G holds the bundle-actuating arm G extended, so as to engage the bundle, and when it runs off said concentric part at the point 9, as shown in Fig. 2, and drops into the cutaway part it allows the said arm G; to collapse and withdraw from underneath the bundle. For the purpose of tripping the discharge-arm again into operative position, another abutment, g, is provided, which collides with the corner of the camafter the arm G has carried the discharger over the shaft and causes the discharger G to swing up into such position that the cam-roll again rests on the track and holds the arm extended while it passes over the concentric portion. Said concentric portion 9 is so situated as to keep the discharger extended while it is passing through the lower and next succeeding quarters of its revolution-that is, while it moves through the locality of binding stubbleward and thence up ward-until itstands projecting upward and stubbleward, as seen in Fig. 2. The entire construction is therefore such as to remove the bundle upward from the position in which it is bound, first carrying sufficiently stubble ward to get it clear of the knottcr. To facilitate this mode of discharge,the breast plate B and the binder-deck B are both extended from the locality of binding in a direction and to an extent corresponding to the movement of the discharger, so that said breast-plate and deck terminate upwardly on the stubbleward side of the knotter and form between them a guiding channel or chute for the bundle.

In order to prevent the bundle from falling back when the dischargers withdraw from beneath it, I provide the trap-gates composed of the spring or pivoted arms K K K, which are supported by the bar L,which forms a rimatthe upper edge of the upwardly-extended deck and extend grainward across the path of the bundle as it is carried upward between the extensions of the deck and breast-plate. Said arms have the slanting portion K from their inner or grainward ends extending downward and stubbleward to the stubbleward side of the passage-way. This slanting portion receives the pressure of the bundle as it is moved upward and causes the gate to swing stubbleward about the lower end of said slanting portion, which is the pivotal point, an arm, K being extended downward from the bar L to afford such pivotal support. I find it most convenient to make this gate, including all the parts K, K, and K of one piece of metal rod,which is secured to the bar L and extends downward close to the deck-extension, and at the pivotal point is coiled to form a spring-knee, 7.", which is in effect a pivot, and thence extends obliquely upward and grainward to the proper height, and is then bent stubbleward and hooked over the bar L, the last portion being curved about the pivot. I consider this form the equivalent of that shown in Fig. 13, the only difference being that in-one form the gate is caused to return under the bundle by the action of its spring-knee 7c and in the other the same movement is produced by gravity.

It will be observed that all the mechanism and other parts concerned in binding and discharging the bundle thus far described are located grainward of the drive-wheel, and that the bundle is ejected upward from the locality of binding between the knotter and the drive wheel. This arrangement so compacts the mechanism that the compressor and its actuating parts are necessarily operated without employing any parts projecting any distance stubbleward of the deck-extension upward or occupying much space below the deck. Further, in View of the form of the deck, which curves upward to form the upward discharge chute, the movement of the compressor toward the bundle is almost necessarily in a similar curve. I therefore construct the compressor and its operating mechanism as follows: Upon the needle rock-shaft is supported the compressor-frame M, which is steadied by the engagement ot'its inner end in a groovein the upper edge of the approach to the deck, as seen in Fig.2. Said frame extends from the vicinity of the needle rock-shaft toward the wheel, curving upward, following the form of the deck at that part. It has the slot at below the deck, following the same course to the point m, where it makes an abruptturn down ward in a short curve about a point in the main course of the slot located a few inches grainward of said turn.

The compressor has an arm or tail which has two abntments provided with anti-friction rolls a n, which engage in the slot m, which thus becomes a guiding track for the compressor. The radius of the curved recess portion m of the slot at is equal to the distance from center to center of the two anti-friction rolls. To actuate this compressor along this guiding-track, I provide mechanism, as follows: On the needle rock'shaft is loosely held the sector gear N", and pivoted to its face is the dog Nflwhieh has the spur a", adapted to engage with the snouldcr or notch N on the needle-hub, or, as illustrated, on a removable plate fastened to the needlehnh, for the purpose of adjustment, as hereinafter explained. 'When the dog is engaged in said shoulder, the needle carries the sectorgear N with it while it moves up to encircle the bundle. Upon a bracketnrm of the compressor-frame isjournalee the sector-gear N meshing with and actuated by the sector-gear N, and said sector-gear is extended to constitute a lever, N ",wl1ich is connected by a link, N", with the compressor N, the connection being made at the axis of the anti-friction roll a. Said link comprises parts N and N and the spring N being an extensible link, the spring tending to resist the extension according to a familiar construction of compressonlinks. The dog N has an arm, N,which extends in such direction that when the needle is nearly at the limit of its upward movement it stands up toward the upper binder-frame arm and has an offset or abutment, a, which at that position is in the path of the rear discharger, so that said disehargcr, striking said abutment, disengages the dog from the needle'hnb and leaves the compressor free from any actuation by the needle. For the purpose of adjusting the point at which this disengagement occurs, the

spur n" is made ofa separate piece secured by a screw in as many different positions as there are screw-holes through the segmental flange prolongation n of said spur. For the purpose of adjusting the position at which the comprossor mechanism becomes engaged with the needle rock-shaft and determining the de gree ofcompression which the bundle receives, the shoulder N on the needle-hub is also made in a separate piece from said hub and adj ustably secured thereto in a manner similar to the seenrement of the spur a to the dog N", as before described.

The operation of this mechanism may be described as follows: The grain falling upon the platform is fed by the conveyer in an obvious manner toward the binder, and by the packer-extensions of the conveyer feed-bars is packed in the usual manner on the binderdeck until, by the operation of familiar forms of tripping and clutching mechanism, (not shown,) the binder is brought into action and the needle rises through the deck and carries the cord around the bundle, and, by means of the shoulder N",engaging the dog N, the compressoractuating mechanism is operated and the compressor is drawn along its curved track toward the bundle. At proper time the discharger reaches a position at which its abutment trips over the cornerg of thecain G, and the diseharger is turned down into operative position, passing successively through the positions shown in Fig. 4 and Fig. 5, at which latter position it isjust about to engage the dog N, the compression being at this stage complete and the bundle ready to be ejected. The next instant it reaches the position shown in Fig. 6, wherein the dog N is disengaged from the needle rock-shaft, as more fully seen in Fig. 9, and the reaction of the compressorspring N has 'aused a partial reverse revolution of the segment-gears N and N and has caused the dog N to pass overthe shoulder N. The continued movement of the discharger presses the bundle against the compressor, which,bein g now freed from all other actuation and restraint, travels up its inclined curved track, and, by means of theliuk N h", attached to the lever arm N rotates thesector-gearN and thereby the sector-gcarN, until theparts are in the position shown in Fig. 7, the dog N* having been carried clear of the discharger and by its weight having tipped over so that its teeth or spur it rests on the edge of the piece having the shoulder N and the abutment n on the compressor having reached the recessm" in the track or slot on. The next instant the said abutment has entered the recess, the compressor turning on abutment n? as a fulcrum and reaching the position shown in Figs. 2 and 3, where it no longer otl'ers any opposition to the further upward passage of the bundle. The discharger, continuing its revolution, presses the bundle upward against the trapgate, the slanting arm K thereof receiving the pressure, and said gate yields by folding or turning about the pivotal point at the lower end of said slanting arm, and the bundle passes up to the position shown in Fig. 2,when the trap-gate returns underneath the bundle his and is in position to support it, while the discharger, whose abutment 9 has now reached the end of the concentric part of the cam G, as it is further revolved, falls into the cutawayportion 9*, and the discharger withdraws longitudinally from underneath the bundle, leaving it on the trap-gate, while the discharger reaches the initial position of rest. The bundle is now fully ejected from the binder-that is, from the locality of bindingand itmay be dropped to the ground in any convenient 1nanner. Suitableguides (shown and lettered IV W in Fig. 2) may constitute a chute over the wheel, and successive bundles will push preceding ones along such chute and cause them to fall.

I do not in this application make claims for the combination, with the binder, of the bundle-carrier located above it, nor for the platform-conveying mechanism, nor the combina tions thereof with the packers and abutting devices shown in the drawings, because I-have claimed these features in mypending applications, Serial Nos. 245,054, filed simultaneously herewith, and 265,140, filed February 24, 1888.
