SPECIFICATION forming part of Letters Patent No. 596,918, dated January 4, 1898.

Application filed November 8, 1895. Serial No. 588,257. Nu modeL) To aZZ whom it may concern/.-

Be it known that we, LE ROY WV. STEVENS and LESTER D. SWART, citizens of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Corn-Bushing Machines; and we do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in the novel features of construction and combination of parts hereinafter fully described,reference being had to the accompanying drawings, which illustrate one form in which we have contemplated embodying our invention, and the said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents an end view of a portion of the machine, showing the feeding-table, the hopper, and the feeding-conveyer. Fig. 2 is a detail view, partly in section, showing the mechanism connected with the hopper for antomatically throwing the conveyer into and out of operation; Fig. 3 represents a side view of the. portion of the machine shown in Fig. 1.

In the drawings we have shown so much of the corn-bushing machine as is necessary to a clear understanding of our invention.

A represents the feeding-table of the machine supported in the main frame B. The main frame is provided with vertically-extending standards B on opposite sides of the machine, connected at the top by suitable braces or cross-bars 13 Above the table A is a hopper, which is formed by two curved wings O (l, pivotally mounted upon rockshafts c c, which are supported in bearings secured to the standard B, the said wings approaching each other at their lower end so as to form a hopper. At the front end of the machine each of said rock-shafts is provided with an outwardly-extending arm 0, provided at its outer end in this instance with a segmental portion in the form of a cam 0 To each of the arms 0' is pivoted a rod 0 which passes through a guiding-aperture in abracket c, pivotallymounted on the stand ard B, the said rod being surrounded by a coiled spring 0 which is interposed between.

the said bracket and an ad j ustin g-nut c on the outer end of said rod. These springs and rods serve to hold the wings C in the position shown in Fig. 1, with the end of one overlapping the end of the other until a sufficient weight of cornstalks has been deposited upon them when they will move from the overlapping position onto one in which the ends of the two wings will be more nearly opposite to each other. The tension of the spring a can be adjusted by means of the nut 0, so that the hopper can be set to make the movement described automatically when any desired weight of stalks has accumulated therein. In order that the movement of the two Wings 0 0 shall be simultaneous and equal, they are connected for joint operation by means of an adjustable coupling-bar C, pivotally secured in this instance to a short arm 0 on one of the rock-shafts c and to the arm 0 of the other rock-shaft.

D represents the feeding-conveyer, which is of any usual or preferred construction. This conveyer has its driving-shaft d at the upper end of the same constructed to engage bearingportionsl3 secured to the upper ends of the standards B, and the said conveyer is given any desired angular position with respect to the machine by means of an adj ustable support intermediate its ends. In this instance we-have shown the conveyor-frame provided with segmental brackets E, having a sliding engagement with similarly-shaped brackets E, supported by the main frame of the machine, the said brackets E being provided at their inner and outer ends with sprocketwheels 6 6, over which passes a sprocket-chain secured at e to the inner end of the segmental brackets E. A suitable crank or other operating device -is provided for rotating one of said sprocket-wheels 6, so as to move the conveyor into any desired position,

The driving-shaft d of the conveyer D is provided with a band-wheel d for rotating the same, and we also provide a device operated by one of the arms 0 for throwing the conveyer into and out of operation automatically by the operation of the wings O. In

this instance we have shown the shaft cl provided with a sliding clutch member disecured to said shaft and adapted to engage the hub of the band-wheel d, which runs loosely on said shaft.

(1 represents a sliding clutch-shipping device having a part mounted to slide in one of the standards B or a part connected therewith, the said shipping device having a part engaging a groove in the clutch member (1 and having also a grooved part which is engaged by one of the segmental cams c on the outer end of the arm 0'. (See Figs. 1 and 2.)

The general shape of the hopper is preferably of the form shown, the sides inclining inward from the top toward the bottom. The function of this is twofold. It concentrates the stalks and delivers them to the center of the table and away from the edges, of the table, so that two operators can be placed at the table, one. at each side, and it also enables the weight of the stalks to act upon the sides and force them apart to cause them to turn on their pivots and effect the stoppage or interruption of the feed of the conveyer.

The operation of the device will be as follows: The machine being in operation and the clutch member (1 being coupled with the band-wheel d, the conveyer D will carry the stalks up and deposit them in the hopper formed by the wings. When a sufficient weight of stalks has accummulated in the hopper to overcome the resistance of the springs 0 the wings C C will move a short distance.

During,

apart, as hereinbefore described. this movement the arms 0, connected with the rock-shafts 0, will move upwardly, and the segmental cam 0 which is in engagement with the shipping device (1 on the side of the.

machine adjacent to the carrier D, will operate said shipping device, thus-removing the clutch. d from engagement with the bandwheel d and instantly stopping the operation of the carrier D, so that no stalks will be delivered into the hopper while the wings O are in this position. The hopper and conveyer remain in the same position until the operator by grasping the rod 0 opens the hopper and thereby deposits the stalks upon the table. As soon as the stalks have been delivered from the hopper on the operators releasing. the rod c the springs a 0 will raise the.

wings C G into their normal position and the segmental cam 0 will throw the clutch member (1 again into operative relation with the band-wheel, thus starting the conveyer again.

It is desirable that the hopper shall deliver only a certain amount of stalks to the table at a time, as an excess of material is in the Wayof the operator and increases the labor. By manipulating the adjusting-nuts c the amount delivered at one time to the hopper can be regulated to the desired quantity, depending upon the weight of the stalks. When the stalks are large and heavy, the springs should be adjusted to sustain the greater weight, and when the stalks are smaller then the springs should be adjusted to cause the hopper to operate under alesser weight of material, thus equalizing the feed to the table.

In order that the conveyer D may he set up on either side of the machine, the standards B B on both sides of the machine are provided with bearings B to support the up per end of the conveyer, and each of the rock-shafts c c is provided with a segmental cam 0 engaging the sliding shipping device (1 as will be seen in Fig. 1.

It will also be noticed by reference to Figs. 1 and 3 that the table A may be approached from either side, and that there is a rod e 'on each of the wings C, so that the operator, if there is only one, may stand upon either side of the table to feed the machine, or if two operators are employed one may stand on each side of the table A and feed the machine. In the latter case the stalks will be delivered by the conveyer D over the head of one of the operators, but without interfering in any way with the proper feeding of the machine.

Byreference to Fig. 3 it will be'noticed that the wings O C of the hopper project beyond the end of the supporting-framework formed by the standards B. .This is necessary to accommodate long stalks of corn, and it will be readily seen that the framework can be provided with wings of greater or less length as required for the work to be done without increasing the length of the machine itself, as it is not desirable to have the machine-frame any longer than is necessary.

It may sometimes be desirable to stop the conveyerwhen the hopper is empty or before the weight in the hopper isv sufficient to shift the clutch of the conveyer. In such case the operator can at. any time stop the conveyer by grasping the rod 0 nearest him and pulling the wing toward him. The movement may be only-enough to effect the shipping of theclutch or may be sufficient to dump the stalks in .the hopper upon the table. If it is desired to have the parts remain in position after the conveyer is stopped, the wings are opened sufficient to permit the stalks to descend so farin the hopper that on releasing the bar 0 the springs will cause the stalks to be grasped between the ends of the wings, which will prevent the return of the wings to their overlapped position, and the conveyer will remain in a position of rest. This enables the operator to control the delivery when a small amount of lighter corn intervenes-in a general heavier grade of corn. As the hopper is actuated by the weight within it, in such cases more than the amount desired at one time would be deposited upon the table; but by stoppin the conveyer in themanner just described t is can be avoided and the corn delivered to the table in the desired quantities without readjusting the springs.
