SPECIFICATION forming part of Letters Patent N 0. 447,468, dated March 3, 1891.

Application filed May 27, 1890.

To aZZ whom it may concern.-

Be it known that I, JAMEs MACPHAIL, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Shoat-Carriers, of which the following is a specification.

The object of this invention is to construct a sheaf-carrier in such a manner that it may be dropped downward, rearward, and inward toward the harvestingmachine as it discharges its load, and to this end a supporting-bar is jointed to a frame-work extending from the end of the machine. Fingers are mounted upon this bar parallel to the path of the machine and to each other upon individual pivots, and are also pivoted to a controlling-bar parallel with the supporting-bar, which is connected to the frame-work of the carrier by a hook .or link. The supportingbar is extended inward toward the machine, and fitted with a hook which rests in a notch in series of rods and levers from the drivers seat, one end of which slides through a stationary guide, while the other is mounted upon a pivotal link that in its movement forward and back carries its end through a path which is the segment of a circle whose radius is the link upon which it is mounted. The supporting-bar thus drops downward, rearward, and swings inward. The controlling-bar falls with it, remaining parallel thereto, while the teeth individually pivoted upon both maintain their parallel position to each other and fold nearer to each other as they come toward the side of the machine, thus allowing the bundles to slip, roll, and be combed off by the stubble, while any obstructions that may be in the path of the carrier are avoided.

In the drawings, Figure l is a top plan view of a carrier constructed in accordance with my invention, showing also parts of the har vester-frame. Fig. 2 is an end elevation thereof, showin gthe elevators of the harvester, the deck of the hinder, the controlling-crank, and a View of the carrier frame-work, with the supporting-bar and controlling-bar shown in section upon the line 2 2 of Fig. 1. Fig. 8 is a top view of the carrier with its supportingirame, showing it in dotted lines in its dumped Serial No. 363,324. (No model.)

or inward position. Fig. 4: is a front View of the supporting-bar of the carrier, together with its extension and its controlling device, showing in dotted lines its position when it 5 has been dropped downward, rearward, and inward to dischargeits load or to pass obstructions. Fig. 5 is a cross-section on the line 5 5 of the controlling-bar, showing the deck'in dotted lines, together with the stationary guide for the sliding bar. Fig. 6 is an enlarged View of one of the teeth, showing the method of mounting in detail. Fig. 7 is an enlarged top plan View of the pivot of the supporting-bar, with its extension taking into the notch on the sliding bar. Fig. 8 is an enlarged detail in section of the pivot and bearing upon the line 8 8 of Fig. 1. Fig. 9 is a top view of a modification with the supporting-bar mounted in the rear of the controlling-bar, and the fin- 7o gers resting in pivots more nearly in their center thereon, while Fig. 10 is a detail of a pivotal bearing in my modified form.

A represents the main sills of the frame of the harvester; B, the cross-girts; C, the crossgirt of the elevators, or more commonly called the seat-plank, and D the main wheel, while E is the deck of an automatic selfbinder, E its pivoted drop-extension, and F a stationary board attached to the supporting-frame of the carrier, upon which the bundles drop on their way to carrier and areslid thereon. These sills and girts maybe of any suitable form, of wood or steel, and while,we have shown two girts at the outside of the 8 5 main wheel our construction could be attached as well if there were but one.

Beneath and extending over the deck E are mounted the operating parts of an automatic self-binder, which we have not considered it necessary to show in the drawings, and which receives the grain from between the rollers at e and discharges the same in bound bundles upon the carrier. The deck E, projecting as it does from the end of the harvester, makes it necessary that a supporting frame-work for the carrier be extended from the frame of the harvester, and to this end I bolt to the sill B, near the rear thereof, an outstanding arm G, that extends the distance neces- I-OO sary to place the carrier in the required position to receive the bundles, and is then bent at right angles and extended forward parallel to the sill B and curved downward to form the pivotal support G for the supporting-bar of the carrier. Extendin g diagonally forward from the outer end of the main sill A is a downwardly-curved supporting-arm G that extends to and beneath the front end of the arm G, while from the upper outward extremity of the sillA a second supporting-arm G is extended, and curved downward at its outer extremity and bolted to the bar G. A short brace-bar Gr extends forward from the bar G, from the point of attachment of the bar G and forms the upper part of the pivotal support for the supportiiigbar.

In the modification which I have shown, Fig. 9, the bar G,in place of forming the pivot at its forward outer corner, is bent in and bolted to the frame-work of the harvester. The brace-arm G is extended diagonally backward, and the arm G3 is attached to the cross-girt l3 and is extended forward, and forms with the arm G2 below and G above the pivotal support for the supporting-bar.

The body or bed of the carrier is formed of the supporting-bar II, extending outward from the machine, on which are a series of supporting-fingers 0, attached thereto by individual pivots. These pivotal connections may be formed in different ways; but in Fig. 10 is illustrated a form of making the pivot which is considered preferable. The finger O is closely fitted in a long-sleeved bearing 0, that is rigid on the pivot-post 0, which is mounted in hearings in the supporting-bar II. These fingers are attached to and are retained in their position parallel to each other by a controlling-bar I, to which they are also attached by individual pivots. In the embodiment of the invention in the drawings this controlling-bar is shown in rear of the supporting-bar, while in the modification shown in Fi 9 it is in front of the controlling-bar; but in both cases its action is the same-via, to maintain the fingers in their parallel arrangement, whatever may be the position of the supporting-bar'll'. The supporting-bar II can be of any form desired, and is fitted at its inner end with an elongated slot, which rests upon the supporting-frame at G and turns and drops upon the pivotal bolt 11' of the supporting-frame. The pivot-slot in the supporting-bar II is elongated, so that the bar may drop at its outer end as it moves rearward. The controlling-barI is attached to the fixed part of the supporting frame-work by a link or loosely-hooked connection. Should the construction of our carrier stop at the point that we have now reached in this description, it is plain that the supporting-bar would by its own weight and the weight of the fingers drop at its outer end to the full extent allowed by the elongated pivotal hole at its inner end, and as the machine was drawn forward it would vibrate back. and forth.

To place the control of the carrier with the driver, the supporting-bar II is continued i11- ward and somewhat rearwardly, and its extremity is formed into a hooked portion H which rests in a notch in the sliding bar J, one end of which bar is moved through the stationar guide J attached to the rear part of the supporting-frame arm G, while the other is fitted with a pivoted link J which extends upward and has a bearing on the long bell-crank K. The bell-crank K is held in position by the supports and 7s. A pitman K extends from the lower crank-arm of the bell-crank K to the sliding bar J, while the rod K connects the upper crank-arm of K with one arm of a short bell-crank lever K", convenient to the drivers seat. The driver thus with one foot upon the arm K and the other upon K moves the sliding bar J backward and forward, dropping the carrier downward, rearward, and inward toward the machine and then again bringing it into a receiving position. As the sliding bar J is moved forward, it will be noticed that its front end, which is controlled by the link J will be moved in a path whose line is the segment of a circle of which the link J is the radius, thus at the same time bringing the bar J forward and upward. This movement causes ,the supporting-bar II, the extension of which rests in the bar J, and which is held therein by the weight of the carrier itself and its load, to follow the bar J and the curved portion of the bar II at H slides through the bar J, and thus the carrier falls downward, rearward, and inward to discharge its load. In order to assist in the recovery of. the carrier to a receiving position, a coil-spring L is connected from one of the joints upon the controlling-bar to the next inner joint on the supporting-bar, or vice versa, in the modification in which the controlling-bar is ahead of the supporting-bar. The spring is in no way necessary to my invention,but simply to render it easier in operation.

I am aware that a patent was granted to Edwin M. Ix'ellogg, January 28, l 90,11um- .an obstruction, as does the Kellogg carrier.

\Vhat I claim is 1. In a bundle-carrier, the combination of a supporting -bar, a controllingbar, parallel fingers individually pivoted to both bars, the controlling-bar attached at its inner end to the machine, and the extended end of the supporting-bar having hearings in a sliding bar, one end of which moves through a fixed guide, while the other is held in position by a link and adapted to be moved by a link-andlever connection, substantially as and for the purpose specified.

2. In a bundle-carrier, the supporting-bar H, upon which the fingers rest, extending from the machine at a right angle, or nearly so, to its path, a joint at its inner end to allow the bar to move downwardly to the rear at its outer end, and an inward extension engagingwith a controlling device, substantiallyas and for the purpose specified.

3. In a bundle-carrier, the combination of the sliding supporting-bar J, the inner end of supporting-bar H resting under or jointed thereto, the carrying-link J an arm or lever adjacent to the drivers seat, and a connection therefrom to the sliding supporting-bar J, whereby the operator can move the bar back and forth and thus raise the outer end of the supporting-bar H to receiving position or allow it to trail, substantially as and for 20 the purpose specified.
