BUNDLE-CARRIER FOR HARVESTERS.

SPECIFICATION forming part of :Letters PatentNo. 656,784, dated August 28, 1900. Application filed December 29, 1899.y Serial No. 741,906. (No model.)

To a/ZZ whom t may concern: y

Beit known thatwe, GEORGE ALBERT FAR- RALL and CHRISTIAN INIAUL, citizens of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented new and useful Improvements in Bundle-Carriers for Harvesters, of which the following is a specification.

This invention relates to a bundle-carrier for corn-harvesters designed for collecting a number of bundles of cornstalks which have been successively tied by the Vbinder mechanism and for delivering the collected bundles from time to time.

In corn-harvesters the binder mechanism and the bundle-carrier are usually arranged in rear of the axis of the supportin g and driving wheels. As cornstalks are of considerable height and weight the accumulation of bundles of cornstalks on the bundle-carrier causes the rear part of the machine to Overbalance the front part. This produces an upward pressure on the draft devices when the bundle-carrier is loaded and a downward pressure on the draft devices when the bundle-carrier is light, thereby causing the draftanimals to be subjected alternately to an upward and a downward pressure, which causes very objectionable straining and chaiing.

The obj ect of this invention is to provide a bundle-carrier for this class of harvesters which is so constructed that the weight of the bundles accumulating on the carrier is brought over the axis of the supporting and driving wheels, whereby the balance of the machine is preserved and chaiing and straining of the draft-animals produced by the rocking of the machine is avoided.

In the accompanying drawings, consisting of two sheets, Figure l is a side elevation of a corn-harvester provided with our improved bundle-carrier viewed from the stubbleward side of the machine. Fig. 2 isatop plan view of the same. Fig. 3 is a rear elevation of the same. Fig. 4. is a fragmentary vertical section, on an enlarged scale, of the bundle-carrier and the support at the lower end thereof.` Fig. 5 is a vertical section in line 5 5, Fig. 4.

Like letters of reference refer to like parts in the several figures.

A represents the main frame of the harvester, whichis supported on the grainward side by a supporting-wheeler and on its stubbleward side'by a driving or master wheel a.

B represents the cutter, arranged on the lower yportion of the frame in front of the axis of the supporting and driving wheels.

C represents the conveyer-platform, which is arranged lengthwise of the frame, with its lower portion adjacent to the stubbleward side of the cutter and which leans laterally toward the driving-wheel, so that the grainward bearing-surface of the platform faces slightly upward. The platform and frame are arranged partly in' front and partly in rear of the axis of the supporting and driving wheels and the platform slopes down- Wardly from its wide rear portion to its tapering front portion, e

D represents the binder-deck, which is arranged at an angle to the platform and which extends rearwardly and stubbleward from the' rear end thereof. The binder-deck leans stubbleward at the same angle as the platform and also forwardly7 toward the axis of the supporting and driving wheels, so that its bearing-surface faces partly upward, rearward, and grainward, The `platform and binder deck form the stubbleward side of the throat, through which the cornstallrs are carried during the gathering, cutting, conveying, and binding operations. The grainward side of this throat is formed principally by guidebars E, arranged on 4the main frame along the platform. The throat is provided with a bottom E', which supports the butt or lower ends of the stalks.

F represents the knotter mechanism, which is arranged opposite the binder-deck and which forms part of the binder mechanism, whereby the band is tied around the bundle of stalks. y

G represents the conveyer or feed belts whereby the stalks are carried through the throat to the binder mechanism. l

The construction and operation of the harthe rear end of the binder-deck upon a bundlecarrier, which is constructed. as follows: H represents an inclined rock-shaft, which is arranged adjacent to the rear end of the binderdeck and which is provided with a number of.

rearwardly-extending tines or arms h, which support the bundles. The rock-shaft is arranged with its lower end adjacent to the lower end of the binderdeck and leans stubbleward and also forwardly toward the axis of the supporting and driving wheels at substantially the same angle as the binder-deck, as shown in the drawings. The rock-shaft turns with its lower end in a step-bearing, which is arranged on the lower rear part of the frame. The rock-shaft is preferably hollow, and the step-bearing consists, preferably, of a perforated base or bracket t', supporting the shaft at its lower end, and an upwardly-projecting boss or sleeve fi', fitting into the lower end of the shaft and holding the same against lateral movement on the base. The shaft is held in engagement with its step-bearing by a suitable attaching device-for instance, as shown, by a retainingrod j, passing through a central opening j in the 'base of the step-bearing, a hook jg, formed at the upper end of the rod and engaging over a cross piece'or bolt jg in the lower end of the rock-shaft, and a spring-pin jl, passing through the retaining-rod below the bearing,

as shown in Figs. t and 5. This means of pivotally supporting the lower end of the rock-shaft is very simple and reliable and permits the same to be readily attached to or detached from its step-bearing. The rockshaft is journaled near its upper end in a bearing or sleeve k, which is detachably connected by braces 7d 7a2 with the adjacent parts of the main frame. Each of the tines h is curved or bent in such manner that the several tines together form a receptacle for the bundles delivered from the binder-deck. The tines are secured to the rock-shaft, preferably, by the following means, (shown most clearly in Fig. 5:) Each tine has its end by which it is secured to the rock-shaft constructed with a return-bend composed of a part Z, which stands at right angles to the tine or thereabout, and an end portion Z, which stands parallel to the tine. The rockshaft is provided with two pairs of openings Z2 Z3, one pair arranged above the other pair for the reception, respectively, of the tine 7L and the end portion Z of the return-bend. The tine and the end portion are inserted into these openings and the tine is secured in place by a screw-nut l, applied to the threaded end portion l'. This means of fastening the tine to the rock-shaft is very simple and securely holds the tine against turning.

In the position of the carrier in which the tines are ready to receive the bundles the tines project across the outlet of the stalkpassage or throat at the discharge end of the binder-deck, as represented in full lines, Figs. l, 2, and 3. The tines are held in this position by the foot of the operator pressing against a treadle m, which is pivoted to the front part of the frame adjacent to the drivers seat m and connected by a rod m2 with a rock-arm m3 on the rock-shaft. As the bundles are delivered from the binder-deck they fall upon the tines of the bundle-carrier.

When the desired number of bundles has been collected on the'carrier, the operator releases the treadle m. The weight of the bundles now depresses the tines and swings or rocks the shaft into the position shown by dotted lines in Fig. 2, whereby the load of bundles is discharged from the carrier upon the ground in a pile. The operator now depresses the treadle m, and thereby raises or swings the tines back into their operative position to receive the next batch of bundles. Vhen the bundles are accumulating on the carrier, they are prevented from sliding o the tines by a supporting-plate n, which is attached to the frame adjacent to the discharge end of the binder-deck and which supports the butt-ends of the bundles. The bundles of stalks resting on the carrier lean or incline stubbleward and also forwardly or toward the axis of the supporting and driving wheels, owing to the inclination of the bundle-carrier in this direction. This brings the weight of the accumulated bundles near to or over the axis of the supporting and driving wheels, whereby the balance between the front and rear parts of the machine is preserved whether the carrier is light or loaded. The fore-and-aft rocking of the machine every time the bundles are collected and discharged and the chang and straining of the draft-animals which would result therefrom are thereby avoided.

We claim as our invention- 1. The combination with the main frame, the supporting and driving wheels, and the binder mechanism arranged on the frame in rear of said wheels, of a bundle-carrier arranged to receive the bundles from the binder mechanism and inclining stubbleward and forwardly and upward,toward the axis of said Wheels, substantially as set forth.
