BUNDLE-CARRIER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent: No. 361,978, dated April 26, 1887.

Application filed March 12, 1885.

To all whom it may concern:

Be it known that 1, WILLIAM R. BAKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bundle-Carriers for Grain- Binders, of which the following is a specification.

My invention relates, primarily, to bundlecarriers for grain-binders, hung upon a pivot parallel with the length of the harvester, so as to tilt in line parallel wit-h the advance of the machine; and as to such it consists, in general terms, in constructing them with a bottom composed of two sections, the rear of which is rule-jointed to the other, and with side bars or fenders at the stubble-side, increasing in length from the lowest to the highest. Owing to the comparatively low position which the binding mechanism occupies in the style of machine now almost universally used, and the still lower point at which the grain is dis charged therefrom, a bundle-carrier, if employed, must be placed very near to the ground. With such low-down bundle-carriers, of whatever type, there has been, so far as I am aware, no provision for lifting or permitting them to yieldand automatically rise to pass over obstructions which project above their normal level. This defect I overcome by mounting the carrier upon the lower arm of a cranked support, herein shown as its pivot, the upper arm of which rests in bearings at a suitable height on the harvester-frame,whereby whenever the carrier comes against an obstruction it may be permitted to swing back upon this support, carrying the lower arm up toward the level of the higher, and thereby beinglifted until the obstruction is overtopped and passed.

Various other features and details of construction of my invention will appear from the ensuing description.

In the drawings, Figure 1 is a top plan view of a machine embodying my invention. Fig. 2 is a front and Fig. 3 a side elevation thereof; Fig. 4, a diagrammatic elevation of the bundle-carrier, illustrating its movement when lifted in passing an obstruction; Figs. 5 and 6, respectively, are enlarged details of the hinged dropper -'slats in side elevation and bottom pian; Figs. 7 and 8, respectively, a side and Serial No. 158,627. (No model.)

edge elevation of one of the bearings for the cranked support, intended to permit an additional range of upward movement to carrier; and Fig. 9, a detail of construction of the inner bearing, in which the pivot-shaft of the carrier is supported.

A represents an elevator-frame, which does not, or need not, differ from the usual shape.

B is the drivers seat, (shown as mounted on a plank, C, inside of the elevator, but which may be placed elsewhere, according to the exigencies of the machine) and D is the binding table or decking. The automatic binding mechanism employed in connection with such table is not shown; but it will be understood that the operation of my improvements has no relation to any particular form or type of binder or binding-table.

From the outer end sill of the elevator-frame project two or more arms or braces, e, which support a stationary board, E, immediately beneath the tail of the binder-decking, and forming in effect an inner side to the bundlecarrier F, which is immediately beyond. This carrier is constructed with a front section, f, which is advisably an imperforate flooring, in order that the grain may more readily slip therefrom, and which terminates about in line with the axle. Metal straps f,bolted beneath this front section along its front and rear edges and then suitably bent up, support the horizontal bars f which form the outer side of the carrier. These bars are of increasing length from the lowest to the topmost, and advisably beveled at their ends to accommodate the folding action of the second section of the carrier-bottom and to shut down close to the ground alongside thereof to insure a compact discharge of the load. Said second section is composed of a series of rearwardlyextending slats orfingers,f ,connected by rulejoints to short metallic supports f which are bolted at regular intervals along the rear edge of the first section. The slats themselves are, for strength, also of metal, and they exthe tend sufficiently far to the rear to afford the necessary extent of bottom for the purposes of the carrier. They may be supported by the rule-joints normally in extension of the plane of the first section, but, in order to close the gap caused by the shortening of the lower side bars, are, as shown in Fig. 4, held at a considerable upward inclination to said plane.

The carrier is pivoted upon a bar, G, which extends transversely beneath its bottom about midway between the front and rear edges of its forward section, and is itself supported upon the outer sills of the elevator-frame. A step, from the before-mentioned fixed board E comes beneath the carrier-bottom in front of the pivot and prevents tilting beyond the horizontal in that direction.

N ear the drivers seat is mounted a lever, H, from which a cord, h, is led over suitable guide-pulleys, h h", to connection with an eye formed in the top of an arm or bridge-strap,

h, bolted to the bottom of the carrier near the pivot, and suitably bent to pass beneath. and ,rise on the inner side of the fixed board, thus preventing the carrier from slipping away therefrom. From this board a keeper, h, projects to embrace and steady said strap and to act as a stop or limit to the tilting movement in dumping. \Vhenever the lever is drawn back, the cord pulls upon this arm and the carrier is brought to a horizontal position, in which it will be held by the engagement of the lever-dog with the rear notch in the segment If alongside the lever 5 but whenever the dog is released from such notch and the lever unrestrained the great preponderance of weightbe hind the pivot will cause the carrier to tilt rapidly until its fingers have folded parallel with the ground, as in Fig. 3, and the front section presents a sharp incline. In this position whatever load it may have will be at once combed off by the stubble, and then it will be brought back to the receiving position again by operating the lever.

Now as to the mode in which the second object of my invention is attained-to wit, the yielding or lifting of the bundle-carrier to pass obstructions. For this purpose the carrier is journaled upon the lower arm of a crank-supportin the present instance its tilting pivot bar or shaft Gand the upper arm of this is supported in bearings I and 1 upon the outer sills of the elevator and wheel-frames, so that said bar as a whole may rock and thus swing the lower arm to a level with the higher. To permit such rocking the fixed board is cut away underneath, as indicated in Fig. 3, which cutting away also allows for the movement of the bridge-strap as the carrier is carried up with the arm on which it rests. From this it will be understood that whenever the carrier comes in contact with an obstruction of too great height for it to pass in its normal position the advance of the machine and the resistance of the obstruction will cause it to swing back and upupon its cranked support until it can ride over the obstruction. To permit a little further yielding over that due to the swinging movement the outer bearing, I, for the upper arm of the support is vertically elongated, as at i, Fig. 7, so that the arm may rise therein, and the inner bearing is contracted at its center, forming what may be termed a dice-box bearing, to allow the arm the necessary hinging movement for this purpose. Thus any obstruction that enters beneath the forward end of the carrier, but is still too high to pass beneath the center after the support is swung to its limit, will lift such support in its bearing, and so escape.

The driver will of course see that the carrier is not brought against anything that it cannot pass over, the measure of which will be practically whatever the harvester itself cannot pass over.

In the present machine it will be necessary to release the lever as 'the carrier reaches an obstruction and so control it as to feel the obstruction all the time, paying outjust enough cord to compensate for the backward swing without allowing a chance for tilting. Vith carriers differently operated this may not be essential.

I claim as my invention- 1. The combination, substantially as hereinbefore set forth, in a bundle-carrier, of the bottom composed of two sections, the rear of which is rule-jointed to the other, and the side bars increasing in length from the lowest to the topmost.

2. The combination, substantially as hereinbefore set forth, to form a bundle-carrier for grain-binders, tilting in the line of advance of the machine, of the pivot-shaft projecting from the harvester-frame transversely to such advance, the front bottom section beneath which said shaft extends, the rear bottom section composed of finger-bars rule-j ointed to the other, and the side bars of increasing length from the lowest to the topmost.

3. The combination, substantially as hereinbefore set forth, in a bundle-carrier, with the front bottom section and the side bars increasing in length from lowest to upper, of the rear bottom sect-ion rule-jointed to the front in such manner that it rises obliquely therefrom to practically close the gap caused by the shortness of. the lower side bars.

4. The combination, substantially as hereinbefore set forth, of the rearwardly-tilting bundle-carrier, its hinged rear bottom section, the fixed board forming its inner side in the receiving position, the step passing from said board beneath the carrier in front of its pivot, the bridge-strap from said carrier embracing the board from beneath, and the keeper from said board embracing the strap and acting as a stop to limit therange of tilting in the dumping operation.

5. The combination, substantially as hereinbefore set forth, of the rearwardlytilting bundle-carrier, the fixed board along its inner side, the bridge-strap, the lever on the harvester, the cord connecting said lever with the bridge-strap, and the intermediate pulleys.

6. The combination, substantially as hereinbefore set forth, of the rearwardly-tilting bundie-carrier, its slatted rear bottom section rule-jointed to the front section, the fixed board parallel with the inner side of the car- IIC rier, the bridge-strap from the front bottom section of said carrier, the lever on the footplank of the harvester, the cord connecting said lever with the bridge-strap, the intermediate pulleys, and the stops for the carrier.

7. The combination, substantially as hereinbefore set forth, of a sheaf-carrier and aswinging pivotal support therefor adapted to permit the carrier to yield rearwardly and rise to pass obstructions.

8. The combination, substantially as hereinbefore set forth, of a bnndle-carrier and a cranked support therefor, to the lower arm of which said carrier is journaled, while the upper arm oscillates in bearings at a suitable height on the harvester-frame, whereby the carrier is permitted to swing backwardly and upwardly to pass obstructions.

9. The combination, substantially as hereinbefore set forth, of abundle-carrier, a cranked support, to the lower arm of which said carrier is journaled, while the upper arm oscillates in bearings at a suitable height on the harvester-frame, and a vertically-elongated outer bearing for said upper arm,whereby the support may be lifted as well as swung.

10. The combination, substantially as hereinbefore set forth, of the bundle-carrier, its cranked pivot-shaft, the bearings which support the upper arm of said shaft on the harvester-frame and permit it to oscillate, that the carrier may yield rearwardly and rise to pass obstruct-ions, and means for controlling the carrier in its tilting and also in its yielding movements.

11. The combination, substantially as hereinbefore set forth, of the carrier F, with its hinged rear bottom section, the cranked pivotshaft G, and its bearing I and I, the lever H, connecting-cord h, and the guide-pulleys for said cord.
