BUNDLE-CARRIER FOR CORN HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 687,264, dated November 26, 1901.

Application filed December 28, 1900. Serial No. 41,353. (No model.)

To all whom it may concern: I

Be it known that we, JOHN W. PRIDMORE and EDWARD A. JOHNSTON, citizens of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented a new and useful Shook or Bundle Carrier for Corn-Harvesters, of which the following is a specification in its best form now known to us, reference being had to the acr'o companying drawings, in which similar figures indicate the same parts throughout the several views.

Our invention relates to shock or bundle carriers particularly adapted to the class of corn-binders which bind the corn while standing vertical and then discharge it.

The object of our invention is to provide a shock-carrier for such a binder in which the bundles of corn can be carried in vertical position and accumulated to form a shock and the shock placed on the ground without in the meantime'allowing the cornstalks to depart substantially from the vertical position, thereby saving the great labor required to '2 5 raise the heavybundles of corn, often ten to fifteen feet in length, from the horizontal to the vertical position.

Our invention also relates to the details of construction hereinafter more fully described and claimed.

In the drawings, Figure. 1 is a side and Fig. 2 a plan view of a corn-binder of a general type now in use having our shock-carrier applied thereto. Fig..3 is a detail view of a spring-latch. Fig. 4 is a'front view of our invention with'the platform tilted as shown in dotted lines of Fig. 1.

While this shock-carrier may be used on any harvester, it is especially adapted to be used on harvesters which bind the corn vertically, a well-known form of which is illustrated in the drawings, where the main wheel 12 carries the main frame 13 of the machine. On this frame are mounted the guides 14 and 15, adapted to straddle the row of corn. As

the binder passes along the row the corn is carried in between these guides by toothed chains (not shown) and cut by the knives 16 and 17. It is then bound by the upright binding mechanism 19. (Not shown in detail. In such machines as heretofore used the bundles are then allowed to pass between the guards 20 and 21 and fall on their sides on the ground or on some form of bundle-carrier, from which the bundles are subsequently dumped upon the ground, wherethey fall sidewise. In either case they have to be lifted and arranged in shocks. In order to avoid the heavy labor of raising the bundles of corn from horizontal to an upright position, we pivotally attach to the frame of the binder at 23 the supporting-bar 24, which is supported at its outer end by the truck-wheel 25. The outer end of this bar is stayed by the bar 26, connected to the forward partof the machine at 27. Mounted on rollers 28 and 29, which are adapted to roll on the bar 24 and which are held upon the bar by the straps 30, is the platform 31, adapted to receive and carry in upright position the bundles of corn. Rising from this platform are the posts 32, supporting the railing 33, which serves to keep the bundles u poll the platform. Secured t0 the under side of this platform 31 at 34 is a chain 35, which passes over the pulley36 at the outer end of rod 24 and pulley 37, attached to the frame of the binder, and has its other end I secured at 38 to the front of the frame of the bundle-carrier. The flexible chain 35 has its point of attachment 34 under the platform 31 so placed that when the platform is shoved up close to the hinder the chains will be tight, and the platform will be thereby supported substantially horizontal, as shown in full lines in Fig. 1. When the platform is shoved to the outer end of the rod 24, as shown in Fig. 4, the portion of the chain which was inside the pulley 36 being discharged enables the platform to tilt under the weight of its burden into the position shown by dotted lines in Fig. 1, thus permitting the shock to slide onto the ground in standing position as the machine advances. The act of forcing the platform inwardthat is, toward th'e'harvester-will under the action of these chain connections restore it to its original horizontal position, in which it will be supported by said chain connections so as to prevent its tilting during the reception of its load until again slid outward for the purpose of discharge, said outward movement releasing this support and permitting it to tilt to position illustrated in dotted lines, Fig. 1. In order to hold the platform in position close to the binder, we provide the spring-latch 39, which may engage the collar 30. (Shown in detail in Fig. 3.) It is manifest that the weight of the corn on the platform tends to tilt it and in so doing tends to assist in moving the platform outward.

In operation a team is hitched to the binder, and it is drawn through a field with the guides 14 and 15 straddling the row. The machine cuts and binds the corn in the manner heretofore described. As the bundles are bound and ejected from the binder they are seized (while still upright) and transferred to the platform 31 so as to rest thereon in vertical position. This may be done by a man riding on the platform 31 for this purpose. This continues until sufficient bundles are accumulated to constitute a shock, when they are bound together near the top, and the shock thus formed is discharged by pushing the platform outward, as above described. By constructing and attaching the shock-carrier on the opposite side from the harvester in the manner described the balance of the machine is maintained, the carrier brought into 'such position relative to the binding apparatus that the bundles can be readily transferred to it and stored upon it while the machine is in operation, and the shock when bound is discharged farther from the machine (and hence farther from the path of travel in the next round) than the position it occupies when on the carrier.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A shock or bundle carrier havinga tilting platform adapted to receive and carry the bundles upright and to slide laterally, and a support which maintains said platform against tilting when in receiving position which permits it to tilt for discharge when moved outward and restores it to its horizontal position when moved inward, for the purpose described.

2. In combination with the laterally-movable tilting platform of a shock or bundle carrier, a horizontal bar on which the platform is adapted to slide and tilt, means for sustaining the platform substantially horizontal on said bar, flexibly connected at its opposite ends with the platform, and an intermediate support around which such flexible connection passes and toward which the platform moves when dumped, whereby the outward movement of the platform permits it to tilt for the discharge of the load thereon.

3. In a bundle 0r shock carrier, the combination of a tilting platform adapted to slide laterally, a substantially horizontal support on which it slides and a chain connecting at opposite ends to and supporting the platform in substantially horizontal position, said chain passing around a sheave fixed at a point in advance of the platform and having an intermediate support in the direction in which the platform moves when dumped, whereby the lateral movement of the platform permits it to tilt for the discharge of the load.

4. In combination with a harvester, a shock or bundle carrier having a tilting platform adapted to receive and carry the bundles, said platform being movable laterally for the purpose of discharge, and a support which maintains said platform against tilting when in receiving position and permits the platform to tilt when moved laterally from the harvester, substantially as described.

5. In combination with a harvester that binds and discharges its bundles upright, a platform adapted to receive the bundles and carry them in an upright position, a pivoted support for such carrier on which it slides laterally from said harvester and tilts for discharge, connections which maintain the platform substantially horizontal when in receiving position and yields to permit its tilt when the carrier slides outward, for the purpose described.

6. In combination with a harvester, a platform adapted to receive the bundle and carry it in an upright position, and slidable laterally of the harvester on a fixed support; means for normally locking the platform to the harvester and means whereby when the platform is released the load upon the plat form tends to automatically cause it to move outward and tilt, substantially as described.
