SPECIFICATION forming part of Letters Patent No. 431,312, dated July 1, 1890.

Application filed October 4:, 1888. Renewed November 29, 1889. Serial No. 381,870. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM It. BAKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi- 5 nois, have invented certain new and useful Improvements in sheaf-Carriers, of which the following is a specification.

Letters Patent of the United States Were granted me on the 26th day of April, 1887, No. 361,978, for an improvement in bundlecarricrs for grain-binders, consisting substantially of a carrier mounted upon a pivotal support transverse to the line of advance of the machine in such manner that if its forward end should come in, contact with an obstruction the carrier would yield and rise so as to ride over such obstruction. In said machine, however, the pivotal support consisted of the lower horizontal arm of a crankshaft, th e upper a 1' m of which rested inbearin gs on the harvester-frame, and therefore whenever the carrier yielded it did so simultaneously both at the stubble and grain side, and thus a resistance equal to the whole weight of the carrier and the load thereon was opposed to the yielding movement and had to be overcome by the team. In said machine also the guard at the outer or stubble side of the carrier or support was attached to said carrier and tilted with it, and as the rear half or section was hinged to the forward half this guard had to be cut away from the top toward the bottom, that the lower rear corner might not interfere with the tilting movement.

In my present invention I propose to mount the carrier upon independcntlypivoted de pending supports, one at the grain side and one at the stubble side, upon the lower end of which it tilts, and either of which can be swung upward independently of the other, so as to permit the carrier to yield at either side without lifting the other side, or to yield at both sides simultaneously in case an obstruction is met right in the center. Furthermore, I have found that where the hinged rear section is employed a single bar or board supported from the frame at a suitable height above the outer side of the carrier sufficiently protects the sheaves from falling off, while its weight is not added to that of the carrier to be returned to position by sheer strength of the driver, as in the former invention. All of this will be understood from the ensuing description and from the drawings, in which Figure 1 is a top plan view of so much of a carrier-framewith a carrier applied thereto as is necessary to a full understanding of my present invention. Fig. 2 is a rear elevation, partly in section, of said harvester frame and carrier, showing also the elevator-frame and grain-deck. Fig. 3 is an elevation from the stubble side of my improved carrier. Fig. l. is a vertical section through said carrier, taken on a line parallel with the advance of the team, showing also the dumping position in broken 6 5 lines. Figs. 5 and 6 are respectively enlarged details of inner and outer brackets on the carrier-frame bar for carrying the depending links to which said carrier is pivoted; Fig. 7, an enlarged detail of one of the hinge-con- 7o nections between'the two sections of the carrier; and Figs. 8 and 9, respectively, the inner and outer keepers for the frame-bar.

A represents the rear platform-sill, A the rear elevator-sill, B the front platform-sill and finger-bar, and B the front elevator'sill, of a harvester, these sills, except the front platform-sill, being herein shown as formed of square pipes, asare also the cross-girts of the elevator-frame, but this form being selected only asan exponent of any suitable construction.

C is the main wheel, and D the outer girt; and E represents the grain-deck receiving from the elevator E, and having at its foot or discharge end a tail-board E as usual in modern grain-binders. Automatic binding mechanism will of course be located over and beneath this grain-deck; but I have not deemed it necessary to show any in the draw- 0 ings.

F is the supporting-frame bar, preferably of square pipe, having its inner end passed through keepers ff on the two outer girts at the front of the machine and secured by a 5 pin. In order to sufficiently advance the front end of the carrier, this supporting-bar is bent forwardly, as at F, a short distance outside of the keepers, and then again becomes straight and transverse to the line of advance of the machine, as shown. Secured to said supporting-frame bar or carrier-1 frame bar) as it may hereinafter be called, are two brackets G G, of substantially the same shape, one adjacent to the harvesterframe and under the front of the grain-chute and the other at the extreme outer end. Each bracket has an inclined seat g, protected by vertical walls, and to these walls are pivoted the upper frontends of links or arms H, which i are supported in an inclined position by the seats, but are free to rise from such position. The lower ends of these links are formed with bearings, which receive pivots 7L from the bot tom of the carrier K, which latter is preferably formed in two sections, the rear section K being connected to the forward section by rule-joints 70, so that when the carrier is in its receiving position both sections may be borne in a horizontal or slightly cradling position,

but that when the carrier is tilted the rear section may be folded as it strikes upon the ground and trail upon the stubble, while the forward section continues to tilt until its rear I end touches or nearly touches the stubble into contact with an obstruction during the.

advance of the machine, either when in its receiving position or in its tilting position,

the link-support at the side nearest to which the obstruction has been met will rise, lifting up the carrier at that side and allowing the obstruction to pass beneath, while should the obstruction strike the carrier fairly in its center both supports will immediately rise and both sides of the carrier be simultaneously elevated.

At the inner or grain side of the carrier is a guard bar or board L, bolted to an ear Z from the bracket G and supported rigidly thereby just beneath the front of the grain-chute and preventing sheaves from rolling off at that side, while at the outer side is another bar M, bolted to the supporting-link at that side of the carrier and extending rearwardly therefrom horizontally to prevent grain from rolling off at that side. This outer board or guard will not partake of the tilting movement of the carrier, but, being bolted to the swinging; link-support, will move up parallel with the carrier whenever the latter rises to pass an obstruction and therefore will itself be lifted out of the way of such obstruction. The tilting movement is controlled from the drivers seat by means of a long bell-crank N, mounted in a bearing a on the inner bracket on the carrier-frame bar and also at the other end on abearing 11, supported from the seat-plank of the machine or over a suitable part of the frame. The crank n at that end adjacent to the carrier is connected by a link N with a bracket or standard N rising from the inner edge of the carrier at the pivotal point or closely adjacent thereto, while the crank 17. at the other end receives one end of a footbar N extending rearwardly over the seatplank and journaled upon a wrist-pin from one arm 0 of a small bell-crank O, the other arm 0 of which extends to the rear alongside the inner edge of the seat-plank and has a foot-piece 0 which when depressed draws the bar to the rear and tilts the carrier to discharge the load, while a push by the foot upon the end of the bar carries it to the front and sets it in position to receive from the binder. A strap 0 is applied to the end of the foot-bar, so that the foot which rests thereon may either be used alone to draw the bar back and tilt the carrier or it may be used to assist the other, which operates the crank.

It will be understood that I do not intend to limit myself to the precise and specific construction described herein, since it is obvious that the independent swinging supports for the sides of the carrier may be differently arranged and differently controlled, and that the construction of thccarrier itself may be altered from that shown, and that the controlling and operating mechanism may be of any suitable construction now known in the arts adapted to tilt and reset the carrier, without departing from the spirit of my invention.

What I claim is 1. The combination, substantially as hereinbefore set forth, of a supporting-frame, the depending swinging supports independently pivoted to said frame, stops for said supports to stay them in a normally-inclined position, the carrier pivoted to the lower ends of said supports in a line transverse to the advance of the machine, and controlling devices by which the carrier is tilted in said supports.

2. The combination, substantially as hereinbefore set forth, of the carrier-frame bar, the brackets thereon having seats or stops, the depending links pivoted in said brackets and normally resting upon said seats, the carrier pivoted to the lower ends of said links in a line transverse to the advance of the machine, and the tilting devices.

3. The combination, substantially as hereinbefore set forth, with the carrier and its depending swinging supporting-links, of the outside guard-bar supported from the outer link.
