BUNDLE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 336.251, dated February 16, 1886.

Application filed April .12, 1885.

Be it known that I, SAMUEL MILLER, of Pierre, in the county of Hughes, Dakota Territory, have invented certain new and useful Improvements in Bundle-Carriers, of which the following is a specification.

My invention relates to bundle-carriers for grain-binding machines; and it consists in a novel construction and arrangement of parts, whereby the carrier is caused to tip positively at predetermined intervals, and to remain at rest in a tilted or inclined position for a sufficient period of time to insure the complete discharge of the bundles.

The invention further consists in a bundledischarger for insuring the delivery of the bundles from the carrier.

Figure 1 is a perspective view of my improved carrier,showing the gearing by which it is actuated. Fig. 2 is a perspective view from the rear outer corner of the carrier, showing the latter in the act of tipping. Fig. 3 is a side view of the carrier, showing it in position to receive the bundles. Fig. 4 is a similar view showing the carrier fully tipped and at rest. Figs. 5 and 6 are views illustrating the action of the gear by which the tipping is effected.

Heretofore bundle carriers have been arranged to tip automatically and means have been provided whereby the intervals of tipping might be varied and controlled as desired; hence neither of these features is broadly claimed. In some prior devices of which I have knowledge, however, the carrier has been arranged to tip and move back to place as one continuing movement, and as a consequence it has frequently happened that the carrier resumed its horizontal position before the bundles could be entirely discharged. This difficulty has resulted either in an unequal number of bundles in a shock, or, more commonly and more seriously, in the dragging of the bundles over the ground, and the consequent thrashing out of grain. From careful observation of the machine in action I have found that two things are necessary: first, that a delay period or interval of rest be allowed when the carrier is fully tipped, so that the bundles may have time to pass from the carrier; and, second, that an ejector be pro- Serial No. 163,056.

vided to insure the discharge of the bundles. The first of these I deem essential, the second advantageous and important, but not absolutely requisite.

The drawings illustrate a convenient form of mechanism for the purpose stated; but various modifications as to details will readily suggest themselves to the skilled mechanic.

A indicates a portion of the framing of a harvester and binder, which may be of any desired type,and B a shaft which rotates continuously or otherwise during the travel and operation of the machine.

In practice any convenient shaft that makes one revolution for every bound bundle may be selected from which to drive the bundle carrier automatically, and motion may be imparted therefrom to the operating-shaft O of the carrier by gearing, belt, or chain, or any other common means of transmitting power and motion. Under the arrangement here shown the shaft B is furnished with a pinion, D, which meshes with and gives motion to a gear-wheel, E, secured upon shaft 0, the rela tive sizes of the pinion and the gear-wheel being such that the shaft B makes four revolutions to one of the shaft 0, and in practice it must makea revolution for each bundle in the shock. Shaft O is suitably journaled or supported in the framing A and carries at its outer end a mutilated gear-wheel, F, which may be de scribed as a circular disk having a smooth periphery, with the exception of two short toothed portions, (1 and b, separated by a short toothless space, 0, and a long toothless space, 61. The wheel or disk F rotates in the direction indicated by arrows in the several figures, and at the forward end of the toothed sections are placed projecting lugs or fingers e and f, which are formed upon or secured to the face of the disk.

G indicates a shaft suitably journaled in framing A and carrying at one end a stoppinion, H, having twostop-faces, g and h, curved to conform to the smooth periphery of wheel or disk F, and two pins or studs, z and j, against which the fingers e and fstrike to throw the toothed portions of the pinion into mesh with the toothed portions of the disk or wheel F. This form of mechanism for secur ing an intermittent motion or rotation of a well understood; hence its principle of operation need not further be explained.

ordisk F into mesh.

As the disk or wheel F rotates with its smooth face din contact with its stop-face g of pinion H, said pinion and the shaft G, to which it is keyed fast. remain at rest; but when finger e strikes pint it turns the pinion far enough to cause its teeth is to mesh with teeth a of wheel or disk F, the teeth insuring equal surface-speeds of the two and the exact turning of the smooth faces to effect their proper meeting.

The pinion H, actuated by the finger e and gear-teeth (1, makes one half-revolution. Then the stop-faceg and the smooth portion a of wheel of disk F comes into contact and the pinion remains at rest, firmly locked against further movement, until fingerf strikes pinj (which is brought into the path of said finger by the semi-rotation of the pinion) and brings teeth Z of the pinion and teeth I) of the wheel When thisoccurs, the pinion makes one half-revolution and comes to rest with its face h in contact with face 01 of thedisk.

The smooth face 65 extends about two-thirds zthfi way around the disk F, andthe pinion time to leave the carrier.

therefore remains at rest for quite a long peries at its outer end a crank-arm, I, which isv connected by a link, J, to the tipping carrier K, which latter consists of a flooring and suitable sides, the rear end being entirely open and unobstructed and the frontend closed by rier and its load.

a swinging gate or ejector, L. The carrier is pivoted at m upon a rod or othersupport, suitably sustained to carry the weight of the carrier is sustained by links M, connected at their lower ends to the carrier, and at their upper ends to the side beams or bars of the swinging ejector L, which latter is suspended from its L upper end and swings upon its pivot 11', asindicated. The bars or slats of the ejector are extended down between the bars of the floor of the carrier, so that their lower ends rise above the floor only as the ejector reaches the limit of its movement, it at all. Being thus constructed, the operation is as follows:

Motion being imparted to shaft B through the advance of the machine,said shait,t.hrough its pinion D and the gear-wheel E, gives motion to shaft 0. As said shaft 0 rotates it carries with it the disk or wheel F, which rotates without affecting other parts until finger e encounters pin 13, whereupon the shaft G is caused by said pin and finger and by the teeth a and k to make a half-revolution, carrying crank-arm I from a pointvertically below'to a point vertically above shaft G, and therebytipping the carrier upon its pivot m. As the carrier thus tips the links M,

The forward end of the car-" which have their upper ends thrown somewhat out of the vertical position and toward pivot m, throw the lower end of ejector or gate L toward the rear end of the carrier, as plainly shown in Figs. 2 and 4. thus forcing the bundles toward the delivery end of the carrier. Faces a and h of the disk F and pinion H come into contact as soon as the teeth a and Ir. pass out of mesh, and while face 0 is traveling over face h the shaft 0 remains at rest and gives the required dwell or interval to insure the certain discharge of the bundles.

Any form of variable gear may be employed to cause the discharge of a greater or a less number of bundlesvat a time, this featurebe-v ing, however, quite old, and therefore not specifically described and shown.

Having thus described my invention, whatI claim is- 1. In combination with a tipping bundlecarrier, gearing, substantially such as shown,
