AUGUSTUS JEWELL, OF DQWAGIAC, MICHIGAN.

VSUHEAF-CARRIER.

SPECIFICATION forming part of Letters Patent No. 414,909, dated November 12, 1889. Application filed August 17, 1889 Serial No. 321,166. (No model.)

' Michigan, have invented a new and useful following is a specification.

My invention relates to that class of attachments to self-binding harvesters known as sheaf or bundle carriers, which are designed to receive and hold a number of bundles after being bound and dump them in a pile at stated intervals in the field, so as to facilitate the placing of them in windrows, in contradistinction to dropping indiscriminately over the field each bundle as soon as bound. Such devices are usually placed at the bottom or discharging end of the inclined deck or binding-table, and some. of them are in the nature of arms pivoted to dump the load by swinging to one side, while another thus reducing to a minimum the power required to operate the dumpmg devices, and

whereby also the dumping devices are effectively operated andlocked by the foot of the driver, and the carrier also enabled to make a better dispositionof its load, as hereinafter fully described.

Figure 1 is a side elevation of the bindingtable provided with my sheaf-carrier, with the movement of the arms of the latter indicated in dotted lines. Fig. 2 is a plan view of the same. Fig. 3 is a front elevation of the same.

Fig. 4 is a perspective view looking from the side of the binding-table that carries the drivers seat. Fig. 5 is a perspective view of a modified form of the sheaf-carrier; and Fig. 6 is a side view of the sheaf-carrying arms, showing how the sheaves pile up on the same in two layers from the peculiar shape of the outer ends of the arms.

-A, Figs. 1 and 4, represents the inclined deck or binding-table, which is mounted upon a subjacent frame B, and the upper end of which table is sustained by inclined braces B"B This frame and binding-table are adjusted at the'side of the platform and just in rear of the cutter-bar, and the grain which is cut and falls over on the platform is carried up to the top of the binding-table or inclined deck by an endless traveling belt.

The cutter-bar platform and elevator-belt are not shown, as these are of the well-known ordinary construction.

It will be sufficient to remember that the plane of the incline deck is parallel to the direction of the movement of the machine in the fieldi. e., the inclined edges of the binding-table face to the front and rear and the device moves in the direction of the arrows in Figs. 2 and 3.

At the lower edge of the bindingtable there is arranged a stout bar 0, Figs. 1, 3, and 4, supported at its ends upon the arms 0, attached to the base-frame B. This bar 0 supports the bundle-carrier, which consists of two hinged metal arms D D in front and two hinged arms D D in the rear, which four, when in their normal positions, project approximately in horizontal direction from the lower edge of the binding-table and support the accumulated bundles, which, when discharged from the binding devices, lie transversely upon the arms of the carrier. The inner ends of these arms are each hinged to the bar C about an axis a, Figs. 1 and 3, that is inclined to the vertical, the bearings 12 of the two front arms D being inclined with their upper ends forward (see Fig. 3) and outward, (see Fig. 1,) and the bearings 19 of the two rear arms D being inclined with their upper ends inclined to the rear andv outwardly. The two front arms D D have in dumping a motion to the front, and the two rear arms D D have a motion' to the rear, as in dotted lines, and the inclination given to the respective bearings causes these arms to dip downwardly. and then rise as they move to the front and rear, as shown by dotted lines in Fig. 1, thus more effectually clearing the arms from the bundles in dump-- ing and causing the weight of the bundles to co-operate or assist in the dumping movement. To render this weight of the bundles more effective in helping to dump, the arms at their inner ends are bent at right angles at 0, Figs. 2 and 3, so that the main body portion of each arm is offset from its bearing, the front arms D D being offset toward the rear, or the center of the device, and the rear arms D D being offset toward the center in front of their axes. This offset, however, while preferable in giving greater effect to the weight of the bundles for assisting in dumping, is still not necessary, and may in some cases be dispensed with, as shown in Fig. 5.

The arms forming the bundle-carrierare each preferably made in one piece of metal curved upwardly and inwardly at their outer ends, then extend straight and horizontal for the greater portion of their length, are then bent to form offset 0, then bent again to form the journal at for the inclined bearing, and are then bent again at the end to form cranks d for the operation of the arms. The cranks d d of the front arms D D are connected by a parallel-motioned bar e, which by a pitman f is connected to a crank g on a rock-shaftE at the front of the device. The cranks d d of the rear arms D D are connected to a parallel-motioned bar e, which by a long pitman f is connected to the crank g on rockshaft E, which crank g projects from the rock-shaft in an opposite direction from g. From this construction it will be seen that the same motion of the rock-shaft causes the front arms D D to move in one direction and the rear arms D D to move in the opposite direction, and the inclined position of the axes of the arms causes the two sets of arms, from a horizontal position in juxtaposition, as shown in full lines, Fig. 2,to move away from each other, dipping downwardly as they sep arate and rising again toward the end of their opening stroke, as in dotted lines, Fig. 1, so as to clear the bundles, which drop between, and also avoid conflict with the ground.

The rock-shaft E, which is arranged at the front side of the device, is carried in suitable bearings and extends to the platform F, which carries the drivers seat, and has a crank F, that connects with a link-bar G and pitman H, which latter is attached to one of the cranks I of a. rock-shaft I, having another crank 1 The cranks I and I are each formed with or provided with a treadle or foot hearing, and the driver, occupying the seat J near the same, has his right foot resting upon treadle 1 and his left in position to be placed on treadle 1 hen the treadle I is forced down to its lowest point, the joint with the pitman is thrown down into a line between the rockshaft I and the joint of the link-bar G with crank F, as shown in Fig. 4, and this serves to lock the arms of the bundle-carrier in their elevated or closed position. When the other treadle I is forced down by the driver, it has the effect to open the arms and dump the load, which operation is easily accomplished by the foot of the driver, for the reason that the weight of the bundles on the gravitating arms furnishes the principal power for accomplishing the dump.

At the point t', where link-bar G connects with pitman II, there is a screw-connection, the end of the pitman being threaded and tapped through a screw-threaded hole in the bent end of the link. By turning the pitman in the hole it may be lengthened, and thus the slack may be taken up in the entire train of mechanism, so as to hold the parts firmly when locked, so that they do not shake and rattle.

In constructing the arms of the carrier their free ends are not only curved upwardly, but have also a turn inwardly at .9. (See Figs. 1 and 6.) This serves to effect an important uesult, for when the bundles are delivered upon the carrier and the horizontal part of the arms becomes covered with bundles lying adjacent to each other the next bundle that is tied is driven by the discharg ing-arms K against those previously lying upon the carrier, and the whole row of bundles is pushed outwardly, and as the outer bundle reaches the curve at the outer ends of the arms said bundle rises, and, the tips 3 of the arms being bent inwardly, the bundle rolls inwardly over on top of the layer of bundles beneath, as shown in dotted lines in Fig. 0, thus loading the carrier two bundles deep before dumping the load. This enables me to carry a large number of bundles on arms of a minimum length, which operate at a greater advantage of leverage than long arms.

In making use of the main features of my invention, however, I do not confine myself to the arms curved upward and inward, but may employ in connection with said main features arms which are not turned upwardly at all, or but slightly.

Having thus described my invention, what I claim as new is- 1. The combination, with the binding-table in a self-binding harvester, of a set of sheafcarrying arms arranged to project from under the lower edge of said binding-table and hinged at their inner ends about axes which are inclined to the vertical, the arms at the front having their axes inclined with their tops to the front and being arranged to swing forwardly, and the arms at the rear having their axes inclined with their tops to the rear and arranged to swing rearwardly, substantially as shown and described.

2. The combination, with the binding-table in a self-binding harvester, of a set of sheafcarrying arms arranged to project from under the lower edge of said binding-table and hinged at their inner ends about axes which are inclined to the vertical, the arms at the front having their axes inclined with their tops to the front, and also outwardly, and being arranged to swing forwardly, and the arms at the rear having their axes inclined with their tops to the rear, and also outwardly, and. arranged to swing rearwardly, whereby the two sets of arms swing away from each other in the center downwardly and upwardly, substantially as shown and described.

I 3. El e-combination, with the binding-table in a self-binding harvester, of a set of sheafcarrying arms, the said arms being arranged to project from under the lower edge of said binding-table and hinged at their inner ends to form axial bearings about which the arms swing in dumping, the said arms being oifset laterally from their axes to cause both the inner portions as well as the outer portions of the arms to descend from the gravity of the load in dumping, substantially as shown and described.

4. The combination, with the binding-table in a self-bindin g harvester, of a set of sheafcarrying arms arranged to project from under the lower edge of said binding-table and hinged at their inner ends about axes which are inclined to the vertical, as described, the said arms being ofiset from their axes and provided with cranks, the bars 6 e, pitmen f f, rock-shaft E, with oppositely extending cranks g g at its lower end and crank F at its upper end, a connecting-rod attached to the crank F, and a crank-shaft, with foottreadles jointed to the connecting-rod for the operation of the sheaf-carrier arms by the foot of the driver, substantially as shown and described.

5. The combination, with the binding-table and sheaf-discharging arms in a self-binding harvester, of a set of sheaf-carrying arms projecting from under the lower edge of the table and curved upwardly and inwardly to cause the outer bundles to roll over upon the first layer from the action of the discharging-arms, substantially as shown and described.
