SH EAF-CARRI ER.

SPECIFICATION forming part of Letters Patent No. 401,902, dated April 23, 1889..

Application filed October 4, 1888. Serial No. 237,165. (No modelj) To all whom, it may concern:

Be it known that I, HENRY E. PRIDMOEE, 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 Sheaf-Carriers, of which the following is a specification.

This invention consists in combining with a suitable support arranged parallel with the length of the sheaf to be received a series of independent fingers normally projecting from said support at right angles thereto or parallel with the line of reception of the sheaf,'each finger having a horizontal journal mounted in a bearing that permits it to swing or hinge in a horizontal plane, and suitable means wherebysaid ngersare simultaneously swung to the rear in said bearings and rocked on their journals so that they may close in yto ward the side of the harvester and drop their v ends toward the stubble, all as will be understood from the ensuing description and accompanying drawings, in which- Figure l is a top plan view of so much'of a harvester-frame with a carrier embodying my invention applied thereto as is necessary to a full understanding of said 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 a top plan view, enlarged, of a portion of said harvester-frame and of my improved carrier. Fig. 4 is a vertical section on-the same scale as the preceding through said carrier, taken on a line parallel with the advance of the team. Figs. 5, 6, 7, and 8 are enlarged details of said carrier, seen, respectively, from the stubble side, the rear, the front, and in top plan view; Fig. 9, an enlarged detail -of the carrier-finger; and Figs. 10 and l1 represent modifications, respectively, in side elevation and top plan v iew.

A represents the rear platform-sill and A the rear elevator-sill, B the front platformsill and finger-bar, and B the front elevatorsill, of a harvester, these sills, except the front vplatform-sill, being herein shown as formed of square pipes, as are also the cross-girts-of the elevator-frame; but this form being selected only as an 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, E2, as usual in 5 5 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 drawings. A

F is a supporting-bar, frame-bar, or bracket, preferably bent into shape of a single piece of angle-iron and having front and rear arms, f, bolted to the outside girt of the harvesterframe, bringing the body part or bar proper parallel with said girt and beneath the tail of the binding-deck. To the top of this bar at regular intervals are secured horizontal bearings G, of quadrant form-that is, Haring from the inner side of the bar to its outer side- 7o that the journals mounted therein may move from a line parallel with said bar to a line at right angles thereto and then be stopped.

In these bearings are mounted the short horizontal journals h of the carrier-fingers H, whichare bent or shouldered, as at h', at the end of the journals, to abut against the curved 4guide-rim h2, of the bearings, and from the shoulders are carried some distance on a .straight or nearly straight line downwardly 8o and outwardly, then are curved gradually upwardly and outwardlyso as to form a cradle for the reception of the grain.

As thus far described, it is evident that each individual tooth may be swung to the rear upon the horizontal bearing, and at the same time, by means of its horizontal journal, rocked downwardly. To accomplish this object and simultaneously control and support all the teeth, vertical bearings I are provided 9o upon the outer face of the supporting-bar slightly in advance of each horizontal bearing, these being conveniently formed' by a bore through an overhanging ear, c', from a bracket, I', secured to the carrier frame- 95 bar, which bracket is shown as integral with the horizontal bearing, but may be-separate therefrom, if desired, and a similar bore beneath through the horizontal fiange of said bar. Each vertical bearing receives the Ioo journal la of a bell-crank lever, K, the outer horizontal arm of which has at its end a short pintle, Zt', pivoted in ears from a sleeve or thimble, K', which slides upon the inner straight portion of the adjacent carrier-fin ger to the rear, and serves to support said iin ger at an elevation determined by the position of thel bell-crank arm. The inner horizontal arm of the bell-crank has also pintles or pivots k2, bent downwardly or depending therefrom to enter perforations in the operating-rod K2, whereby, whenever this operating-bar is reciprocated to the front, the outer arms of the bell-crank levers are swung to the rear, pushing the carrier-fingers also simultaneously to the rear, while, owing to the pivotal points of these levers being eccentric to the points where the fingers are mounted upon the supporting-bar, the sleeves or thimbles will in this movement gradually slide up the straight incline upon the fingers, supporting them at a point nearer and nearer to the frame-bar, therefore permitting the horizontal journals to rock in their bearin gs and the outer ends of the fingers to drop vfarther and farther. Whenever, on the other hand, the operatingrod is pushed to the rear, the outer arms of the bell-crank levers will be carried to the front and the sleeves forcibly projected along the inclined parts of the fingers and toward their extreme ends, away from the frame-bar, thus rocking their journals again in the horizontal bearings and lifting the fingers more and more as they approach a direction at right angles to the frame-bar, until finally they are again in their normal receiving-po sition and prevented from rocking downward or upward upon their pivots by the rigid oonnection formed with the sleeves and bellcranks.

The movement of the carrier is controlled froln the drivers seat by means of a long bell-crank, L, mounted in a bearing, Z, at the forward end of the bar which supports the carrier and also at the other end in a bearing, Z', supported from the seat-plank of the machine or over a suitable part of the frame.

The crank Z2 at that end adjacent to the carrier is connected by a link, L', with the operating-rod pivoted 1o the inner arms of the carrier bell-cranks, while the crank Z3 at the other end receives one end of a foot-bar, L2, extending rearwardly over the seat-plan k and journaled upon a wrist-pin from one arm, m, of a small bell-crank, M, the other arm, m', of which extends to the rear alongside the inner edge of the seatfplank, and has a footpiece, m2, which, when depressed, draws the bar to the rear and sets the carrier-fingers in position to receive from the binder, while a push by the foot upon the end of the bar carries it to the front and swings the fingers back to shut toward each other and simultaneously drop, thereby discharging the load.

It will be understood that I do not intend to limit myself to the precise and specific construction herein described, since it is obvious that many changes may be introduced into the frame-work, and even into the controlling and operating mechanism, without departing from the spirit of my inventionas, for instance, I may substitute for the quadrant-bearing the swinging bearing N, carried upon the vertical spindle n, as shown in Figs. l0 and 11, and thereby obtain the same movement of the carrier-fingers.

1. rIhe combination, substantially as hereinbefore set forth, with the carrier-frame bar, of a series of curved fingers projecting transversely therefrom, horizontal journals upon the inner ends of said ngers set at an angle to the length thereof, bearings upon the framebar receiving said journals and adapted to permit them to swing in a horizontal direction, a series of bellcrank levers mounted one to the side of each of said fingers and having one arm connected therewith, and a common operating-rod for each of said levers, whereby the fingers may be simultaneously swung to the rear and rocked upon their journals to drop their outer ends.

2. The combination, substantially as hereinbefore set forth, with the carrier-frame bar, of a series of curved fingers having an inner straight portion and horizontal journals at their inner ends set at an angle to the length of said fingers, bearings upon said framebar receiving said journals and adapted to lpermit them to swing horizontally therein, a se ries of bell-crank levers mounted in bearingsA one in advance of each of said fingers, a sleeve playing upon the inner straight portion of each finger and pivoted to the outer arm of each lever, and an operating-rod connected to the inner arms of said levers.

3. The combination, substantially as hereinbefore set forth, of the carrier-frame bar, the horizontal quadrant-bearings mounted thereon, the carrier-fingers having horizontal journals playingin said bearings and rocking therein, the vertical bearings on said framebar, the bell-crank levers mounted therein, the sleeves upon the fingers pivoted to the outer arms of said levers, the operating-rod connected to the inner arms of said levers, and a lever upon the harvester, whereby said rod is controlled.
