SHEAFI-C'ARRIER.

SPECIFICATION forming part of Letters Patent No. 538,009, dated April 23, 1 895. Application filed September 16,1886. Serial No. 213,652. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM WORTH BUR- SON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful sheaf-Carrier, of which the following is a specification.

My invention relates, first, to an attachment to harvesters whereby the sheaves when bound may be carried until a sufficientnumher have been accumulated and then deposited on the ground by the action of the driver;

second, the dumping process may be done antomatically, when an agreed upon number have accumulated on the carrier; third, the dumping maybe automatically accomplished by contact with the sheaves dropped on the former round; fourth, the carrier folds out of the way of stumps, trees, gate posts, 850., auto-' matically, that is, without the attention of the driver; fifth, a shelled grain attachment is added whereby the shelled grain may be saved. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front elevation, showing also parts of the binder and harvester. Fig. 2 is a side elevation. Fig. 3 is a plan view. The full lines show the carrier in position to receive the sheaves. The dotted lines show an elevation of the carrier folded horizontally, as in passing an obstruction. Fig. 4 shows the carrier folded and turned in a vertical position. Fig. 5 is a detail of the counting attachment to the carrier. Figs. 6 and 7 show belaying stop C. Fig. 8 is a front elevation enlarged from Fig. 1, the arm F being partly removed. Fig. 9 is a plan view of carrier platform. Fig. 10 is an end view elevation of Fig. 9. Fig. 11 is a section of Fig. 5 on line a: 00.

Similar letters of reference denote the same parts throughout the several views.

In the drawings, Figs. 1, 2, 3 and 8, A is a part of the harvester frame or an extension therefrom, and A also a part of the harvester frame, the former supporting the vertically pivotedbearer B, the upper end of which has a horizontal sleeve forming a support for the oscillating arm C in connection with the belaying stop 0. To thearm C are hinged the supports D, D, onwhich are secured the boards or pieces E, E, E E The tripping arm F has fingers reachingdown ward, adapted to engage the sheaves dropped on the former round. It has the runner F and arm F and connecting rod F to be more fully described farther on. F is a support for F.

G is a flexible support for the rear end of the carrier attaching arm D and ext-ending to the driver, not here shown. The spring G is adapted to balance the weight of the carrier as desired.

C is a stop block on G, in which the latch G3 engages being held in position by a spring G His a canvas under the receiving pieces E, E adapted to save the shelled grain, (Figs. 9 and 10.)

I is a ratchet wheel, in this case with twentyfour teeth, upon one surface in which is an operating pawl M.

I is a loose sleeve on. I having the pawl I operating in a notch of I.

I is a cam elevation on I.

I is a keeper for rope J and sleeve I.

J is a cord extending from the sleeve 1' to thespring J connected with the harvester frame.

J is a cord extending-from the sleeve 1 to the reach of the driver.

K is an arm extending from the needle shaft, or may be the needle itself when the construction will so admit of it.

L connects K with the arm M, upon which is the pawl M.

N is a right angled lever, one end of which I the - The connection therewith being so well understood is not-hereshown.

T is the ejector; T the rod connecting it with the packer P, Figs. 1, 2 and 8. The construction of my improved sheaf carrier will be further explained in connection with the description of the operation of the same.

The rod C, which is conveniently made of gas pipe, is supported in a sleeve on the upper end of the piece B which gives it freedom for two motions. It extends through the sleeve in B to a stop catch C which holds it in a recess with sufficient force for ordinary work, but will allow it to pass out and turn backward in B when meeting with sufficient resistance. This saves the necessity for removing the carrier in passing obstructions, as also the liability of breakage when striking against such unobserved. The supports D, D are pivoted to O and adapted to fold close to it.

The pieces E E E E may be made'of boards, or sheet metal. In the latter case'a rod could be run in one edge to stiffen it. I prefer to have them overlap a little the better to facilitate the folding process. The pieces E, E, E E are fastened each to the pieces D, D, along one edge only of each piece bya pivoted fastening, which fastenings should be parallel throughout the several pieces. \Vhen thus attached they will fold together as shown in Fig. 4, each upper piece extending farther back than the one next under it. It will be seen that the pieces D, D, fold alongside of O, and that the pieces E, E, E E fold one above the other, except that the upper piece is in each case farther back endwise than the one directly under it. A cord attaching the rear end of D and extending over suitable friction pulley guides to a lever in reach of the driver gives means for operating the carrier. This part of the mechanism is so well understood that I have not thought it necessary to illustrate it. A spring is conveniently attached to counterbalance the weight of the carrier.

When the carrier is constructed as just described it is ready to receive the sheaves from the binder, and when a suflicient number has accumulated the driver releases the cord G, when the automatic attachment is not used which permits the rear end of the carrier to drop and the sheaves are thereby left on the ground, and on each succeeding round it is desirable to drop the sheaves opposite, the better to facilitate the shocking.

To save the driver the trouble of observing the sheafcarrier and dumping the sheaves at the proper time, I have provided a device for accomplishing the same, automatically, shown in Figs. 1, 2, 8 5, and. 12. This device consists substantially of a drum revolved by a ratchet operating a trip lever, operating to release the catch holding the supporting cord. The drum I is supported on the harvester frame. Lever M has a pawl M operating in the ratchet, to turn the drum. Lever M is operated by arm K, through the connecting rod L. At each movement of tyingthe sheaf, leverK revolves the drumIuntilthe cam block 1 trips lever N, which acting through connecting rod N, releases catch G and thereby dumps the sheaves.

It is desirable to control the number of sheaves dropped in a place. This is done by moving the controlling rod L in the holes in lever M. The nearer the pivoted pointof said lever the connection is made the greater the movement of the pawl and hence the fewer sheaves will need to be tied to revolve the drum and the farther from the pivot the slower the movement of the drum and hence the more sheaves would be bound before the trip cam 1 would reach the trip lever N. When the carrier is tripped automatically as just described an agreed upon number of sheaves must be had before they will be dropped. This is not always satisfactory and hence it is desirable to have the dumping under control of the driver. To meet this requirement the sleeve 1 is put on the drum I. This sleeve has a pawl '1 ,resting on a part of drum I, which has one catch only corresponding to the trip cam 1 A cord J is attached to sleeve 1 and extends to the driver. It will be seen when cord J is drawn, the pawl I will find the notch in drum I no matter in what partof its revolution it may be and turniugit until trip cam I acts upon trip lever N, trip the carrier without regard to action of ratchet lever M, and that the tripping devices will be in proper shape to repeat the operation. When the driver releases cord J, spring J brings the sleeve back one revolution to its original position, ready to act again when desired.

It is desirable to drop the sheaves opposite each otherin Windrows. In the plan jnstgiven, this would not necessarily be done without some means of correcting it. To obviate this difficulty trip rake F having the downwardly projecting teeth a, a, a, a, is adapted to come in contact with the sheaves dropped in the former round and acting through crank F and rod F releases the latch G without regard to theotherdevice. SincethetriprakeFextends so far from the carrying wheels it is effected by the roughness of the ground. To overcome this difficulty the rake arm is jointed over the carrier support B both vertically and horizontally, thereby permitting the tripping device to swing with the carrier in folding, and to rest on the curved runner or shoe F by which it will be guided a proper height above the ground without regard to the position of the wheels. These devices can be used together or separately, or the carrier can be operated entirely under the control of the driver. The ejector T is adapted to act upon the bound sheaf where the discharge arms have moved itout of the place in which it is tied.

It has not been practical heretofore to use a sheaf carrier in badly tangled grain, the discharge arm S, (Fig. 1,) frequently becoming entangled in the grain and thereby failing to properly discharge the sheaf. This is especially the case when a sheaf carrier is used. The ejector T moves the sheaf away from the discharge arm and well out upon the sheaf carrier from which it can be dumped, enabling the latter to be used in conditions of grain heretofore impracticable. This ejector T moves in a guide track T fastened to the' binder frame. It is operated by the rod T? connecting it with the packer P thereby giving it a reciprocating movement.

The operation of binding will generally shell more or less grain which has heretofore been wasted. To save this grain I place a canvas bottom H on my carrier adapted to catch and hold the shelled. grain. The canvas may extend somewhat back of the lower board Figs. 9 and 10 or there may be openings S S in the upper surface of the carrier to permit the passage of the grain. One side of the canvas should be fastened so as to permit the folding of the carrier, as with rings w, 00, m, w, held on a rod D The other side may be fastened rigid Figs. 9, 1'0 and ll.
