SPECIFICATION forming part of Letters Patent No. 471,737, dated March 29, 1892. Application filed Ilugust 10, 1891. Serial No. 402,194. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN F. STEWART, acitizen of the United States, now residing at Plano,in-the county of Kendall and'State of Illinois, have invented certain new and useful ImprovementsinBundle-Carriers for Harvesters, which are fully set forth in the following specification,referencebeing had to the accompanying drawings, in which Figure 1 represents a rear elevation of a harvester embodying my invention, the grainplatform being mostly broken away; Fig. 2, a detail inside elevation of the upper portion of the upright frame of the harvester, looking in the direction of the arrow, Fig. 1; Fig.3, a plan view of the machine shown in Fig. 1; Fig. 4, an end elevation of the machine, looking from the stubble with the'bundle-carrier in receiving position; Fig. 5, a similar view with the bundle-carrier in discharging position; Fig. 6, a detail rear elevation showing the joint of the carrier; Fig. 7, a side elevation of the same looking from the stubble; Fig. 8, a like elevation of the same looking from the inside thereof or opposite to Fig. 7; Fig. 9, a front or reverse elevation of the joint shown in Fig. 6; Fig. 10, a detail section of the same, taken on the line 10 10 of Fig. 6; Fig. 11, a detail section of the same, taken on the line 11 11 of Fig. 10; Fig. 12, a detail plan of the pivot-lug on the carrier-support, and Fig. 13 abottom plan of the corresponding face of the stationary bracket or pivotal sup port.

Figs. 1 to 5, inclusive, of the drawings are on one scale, Figs. 6 to 9, inclusive, upon another and enlarged scale, and Figs. 10 to 13, inclusive, upon a third and still further e'nlarged scale.

In modern automatic grain-binding harvesters a bundle-carrier is now demanded almost as a necessity. It will be understood, of course, that by this I mean a device which receives the bound bundles from the binder and retains them until a sufficient number has accumulated to form a sheaf, when they are to be discharged together upon the ground. Obviously this device must be located in a convenient position to receive the bound bundles as they are discharged from the binder, must have a strong firm support, and must be capable of some kind of turning or tilting movement to deliver the bundles upon the ments in the devicesfor supporting and moving the bundle-carrier, whereby, I believe, I obtain all of the advantages above mentioned.

I will now describe in detail the construction and operation of a bundle-carrier, its actuating mechanism, and so much of a harvester as is necessary to an understanding thereof, in which I have embodied my invention in one practical way, and will then point out more definitely in claims the particular improvements which I believe to be new and Wish to secure by Letters Patent.

In the drawings, A represents the gear-frame of the harvester; B, the platform-frame, and O the upright frame. A is the main or ground wheel; B, the inclined elevator-frame; O, the drivers seat, and D the inclined deck of the binder. These parts are all of. any ordinary construction and require no further description here. It will be understood, of course, that the grain falling upon the platform as it is cut is carried up by the elevator and discharged over the wheel upon the deck, where it is formed in bundles, which are bound and then discharged from the deck or binding-table.

'It is evident, then, that thebundle-carrier must be located so as to receive these bound bundles as they are discharged from the deck. This required arrangement of the bundle-carrier I obtain by means of a support E, which is arranged just underneath the outer edge of the deck .and is securely fastened to the binder-frame D". This support is preferably of metal and in the form of a small U-shaped frame, as seen in Figs. 4 and 5 of the drawings, the arms 6 thereof being firmly bolted to the binder-frame, as seen in Figs. 1 and 4. The frame need extend only part way along the binder-frame and being attached thereto moves with it when the said binder-frame is adjustable, as is the case in most binders at present. The support-inclines downward as it extends outward, so as to bring the bundlecarrier near the ground.

The bundle-carrier F is a kind of cradle consisting of a longhead f, to which is attached aseries of arms of teeth f, slightly curved,as seen in Figs. 1 and 5. This cradle or receiver is mounted so that in normal position the head will be about parallel to the movement of the machine just below the outer edge of the binder-deck and with the arms extending outward directly therefrom, as seen in Fig. 1 and full lines in Fig. 3. Evidently in this position the bound bundles as they are discharged from the deck of the binder will be delivereddirectly upon the carrier. The mounting of this carrier upon the supporting-frame is effected by peculiar devices. The head f of the carrier is preferably a metal tubegas-pipe, for instance, is suitable for this purpose. loosely ina support G, which is sleeved on the headby means of a long sleeve g, which forms a bearing for the headf. At each end of this sleeve there are two lugs g, projecting slightly each way from the sleeve and stand ing normally about in a vertical line. Bolts or pins f are passed through the-head f,their upper ends being arranged in rear of or'behind the upper lugs. on the sleeve, as seen in Fig.8, while their lower ends. pass out in front of the lower lugsof the same, as seen in Fig. 7. Obviously these boltsv fasten the, head of the carrier-tothe sleeve and prevent it, from turning therein in adirection which will permit the arms to drop, so that the latter will normally. be held in the horizontal position.

shown in full lines, Fig. 2. It will also be seen ..strike the opposite faces of the, respective lugs. Hence the carrier is free to be turned up, so as to throw the arms into an upright position, as seen in dotted lines, Fig. l, where they will be out of the way in passing through gates or elsewhere, when the projecting arms will interfere with the movement of the machine. Thearrange-ment of the bolts or pins whereby this movement is permitted, while at the same time the head'is held from oscillation in the opposite direction, is shown in Figs. 6 and 9. The arms f pass loosely through a stay-rod f, by which they are connected and retained.

Obviously, in order to discharge the bundlesfrom the carrier it willbe necessary, however, to depress or turn downward the projecting arms,.'and in order to make the discharge sub.- stantially in line with the movement of the machine, 'asmentioned' above, it willv be necessary toswingthe carrier around to the rear. I accomplish this. result by attaching the. carrier to,itssupporting-bracket by means of a pivotal connection which provides for both of thesemovements in the bu ndle-carrier at the sametime. The sleeve-support G, in which the head of the carrier is mounted, as just described, is provided with a lug or boss 92, rising from the upper side of the sleeve portion g and'having a flat face 9 but arranged at an This head is mounted in Fig. 10. The outer edge of the face portion of the boss is also cut away at the front side, so as to provide a long notch 9 as seen in Fig. 12. This sleeve-bearing of the carrieris pivoted to a bracket H, which in turn is securely fastened to the U-shaped frame E, thus mounting the carrier upon the latter, as stated above. The bracket H is constructed with a long angleshaped seat h, whereby it is adapted to be seated upon the front portion of v the U-shaped frame E and securely bolted thereto, as seen in Figs. 6 and 7. From this seat portion there projects a circular boss hf, which is arranged at an angle to the former and terminates in a flat face 7L corresponding to the inclined face of the boss on the sleeve. The inclination of this boss on the bracketisopposite to that of the sleevethat is, the inclination of the face k is downward and somewhat inward away from the forward end of the seat portion h of the bracket. The sleeve-support G. is pivoted to the bracket H by bringingthe two faces of the respective bosses together and then passing through them a pivot-bolt I, the headof which is received Within therecess 9 as seen in Figs. 10 and 11. The belt is secured by meansof a nut c on its upper end, fastened by a locking-pin t or by any other suitable device. On the face h there is at one point on the outer edge a small lug 71, standing vertically to the face and adapted to enter the long notch g in the edge of the sleeve-boss, as seen in Figs. 7 and 13. Obviously with this mounting the sleeve-support is free to turn upon its pivot within certain limits, which limits are determined by the length of the notch 9 as themovement in either direction will be limited by the lug it coming in contact with one or the other faces of this notch. It is also obvious that, owing to the inclination of the bearing-surfaces of this pivotal jointbetween the sleevesupport of the carrier and the bracket,when the former is swung around to the rear it will also have a turning or twistingmovement downward, which movementwill, give a corresponding downward turn to thelhead of the carrier, thus depressing the arms thereof,

as seen in Figs. 3 and 5 of thedrawingawhich depression of the arms into the stubble effects the discharge of the bundles from the carrier. This swinging movement-of the bundle-carrier to the rear for the purpose of discharg ing bundles therefrom must of course be under the control of the driver, so that he may empty the carrier at will. It is obvious that this may be effected by any suitable systemof levers. As shown in thedrawings,I-providea kind of bell-crank lever J, whichis pivoted tothe front of the upright frame. One arm of this lever is connected by a link-rod j to the forvIIO ward end of the carrier-head f, while the other arm is connected by a similar rod j to a rockshat't K, mounted near the foot of the drivers seat and provided with a crank arm is, to which this rod is connected. The shaft is also provided with a foot-lever k, whereby the driver may at any time oscillate the shaft in the direction required and turn the bundle-carrier backward for the purpose of discharging the bundles and then bring it back again into normal position whenever he sees that a sufficient number ofbundles for a sheaf has been delivered to the carrier. A hand lever may be employed instead of a foot-lever, if desired, and any other arrangement of levers and connections with the carrier suitable for the purpose may be substituted for that herein described. It will be noticed that in swinging the carrier laterally for thepurpose of discharging the bundles, as described above, the head of the carrier swings or turns in substantially the same plane-that is, there is no substantial change in the horizontal position of the head during this swinging movement. The discharge is effected by a downward oscillation of the carrier-head while it is swinging around in a nearly horizontal plane. This is one of the peculiar features of my invention, and I wish to be understood as claiming it without respect to the particular mode of supporting the head, f6r the latter may be mounted by means different from the inclined pivot which I have herein shown and described and yet have substantially the same movements referred to above.

In details of construction there may of course be changes without departing from the main characteristic of my invention, which is the connection of the bundle-carrier to its permanent support in such a way that the head of the carrier may be swung laterally without substantial change horizontally and at the same time oscillated to throw the carrier-arms downward, as described above.

Havingthus described my invention, whatI claim as new, and desire to secure by Letters Patent. is
