CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 769,186, dated September 6, 1904. Application filed November 21, 1901. Serial No. 88,106. (No model.)

To all whom it may concern.-

Be it known that 1, AUGUST ROSENTHAL, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Corn Husking and Shredding Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in corn husking and shredding machines.

One of the primary objects of the invention is to provide a construction whereby the blower and cutter are driven direct from the engine and not through the intermediary ofv belts or gearing on the machine, whereby the power is applied to the part of the machine where the greatest strain occurs and where the maximum power is therefore required.

A further object'resides in the provision of a construction whereby almost the entire system of shafting and gearing is compactly arranged at one end of the machine. I

A still further object is the provision of improved means for severing the band or cord of the bundle of cornstalks and for separating or disentangling said stalks from each other after the band is severed.

With the above primary and other incidental objects in view the invention consists of the devices and parts or their equivalents, as hereinafter set forth. 4

In the accompanying drawings, Figure 1 is a side elevation of the machine. Fig. 2 is an elevation of the opposite side thereof. Fig. 3 is a plan view, and Fig. 4 is a longitudinal vertical sectional view.

Referring to the drawings, the numeral 5 is employed to indicate generally the frame of the machine, which may be of any desirable construction and which for the sake of portability is mounted upon wheels 6. Ar-

ranged longitudinally'of the frame and extending from the front end thereof rearwardly at a decline are husking-rolls 7. The forward ends of these rolls are the separating portions thereofthat is to say, at these portions of the rolls the stalks are separated from the ears, the said forward portions being provided with projections 8 for grasping the cornstalks and pulling them between the rolls, the final separation of the stalks from the ears being accomplished by means of nippers 9, extending a desired distance longitudinally of two of the rolls. The greater portions of the lengths of the rolls-are the husking portions thereof, and some of the rolls of the series are provided with the usual pins 10 for this purpose.

The upper portion of the frame of the machine is in the form of ahopper 11, havingits bottom composed of two oppositely-inclined bottom pieces converging to an opening 12. Mounted upon shafts l3 and 14, respectively, arranged just below the inner ends of the inclined bottom pieces of the trough, are circular saws 15 and 16. These inner ends of the bottom pieces are recessed to provide for the free rotation of the saws. Corresponding outer ends of the shafts 13 and 14 carry beltwheels 17 and 18, which are connected by means of a crossed belt 19.

Extending across the front end of the frame ofthe machine and mounted in suitable bearings projecting from said front end is the main drive-shaft 20. This shaft is rotated directly from the engine by any desirable means or connection. Inthe drawingsIshow for this purpose a belt-pulley 21, mounted upon one of the outer ends of the shaft, said pulley being connected to the engine by means (Not shown.) The shaft20 extends through a fan-casing 22 and also through a casing 23 for'the cutting and shredding mechanism. Extending from the fan-casing is a conduit 2 for conducting the out and shredded material to aplace of deposit. Mounted upon the shaft 20 within the fan-casing is a fan 25, and also mounted thereon, within the cutting and shredding casing, are a series ofcutters or knives 26. Upon the endof the shaft 20 opposite to the end which carries the pulley '21 is mounted a toothed wheel 27. This toothed wheel is in engagement with a larger toothed wheel 28, mounted upon a transverse shaft 29, and said shaft 29 has also mounted gears 32.

thereon a beveled gear-wheel 30, meshing with a similar gear-wheel 31 at the end of the journal of one of the corn-husking rolls.

The opposite journals of all of said rolls carry intermeshinggear-wheels 32. It follows that when the gear-wheel 31 is rotated by the rotation of the gear-wheel 30, carried on shaft 29, all of the several corn-husking rolls will be rotated by reason of the intermeshing The large toothed wheel 28 is also in mesh with a pinion 33, said pinion being mounted on one end of the shaft 14. It follows that when the toothed wheel 28 is rotated the shaft 14 is also rotated, and this rotation of the shaft 14 is imparted to the shaft 13 by means of the crossed belt 19, and consequently the circular saws 15 and 16, carried on the shafts 13 and 14, are caused to be rapidly revolved.

The inner side of the cutting and shredding casing is provided with a mouth or opening 34, and just in advance of this mouth or opening are two feed-rolls 35 and 36, arranged one above the other and mounted, respectively, upon shafts 37 and 38. Shaft 37 has mounted thereon a pinion 39, which is in mesh with a similar pinion 40 on the shaft 38. Shaft 37 has also mounted thereon a larger pinion 40, which is in mesh with the pinion 27 of the main shaft. By this means rotation is imparted to the two feed-rolls 35 and 36.

Below the bushing-rolls is located an endless eonveyer-belt 41, which is preferably arranged at a gradual decline from the forward end of the machine to the rear end thereof.

This belt may be of any suitable form, but

belt passes around two rollers 42 and 43, ar-

ranged, respectively, at opposite ends of the machine, said rollers provided with sprocketteeth for the engagement therewith of the sprocket-chains of the endless conveyer. The said endless conveyer is driven by means of a s procket-ch ain 44, said chain passing around a sprocket-wheel 45 on one end of the shaft 37 and around another and larger sprocketwheel 46 on one of the end journals of the roller 42.- The upper portion of the endless conveyer 41 passes over a slotted platform 47. Below the conveyer and also extending beneath the feed-rolls is a funnel 48, which converges to a discharge-opening 49.

In the operation of my invention rotation is imparted to the main shaft 20, and this through the described gearing and connections Will cause movement to be imparted to the several rotatable and movable portions of the machine. A tied bundle of cornstalks is deposited in the hopper 11 with the ears of the stalks pointing toward the rear of the machine. The rotation of the circular saw 15 will efiect the cutting of the band or cord of the bundle and will also tend to thrust and keep the bundle in engagement with the front saw 16. The continued rotation of both saws, and more particularly the saw 16, will, after the cutting of the cord is effected, separate and divide the intertwined stalks, and said loose stalks will then pass through the opening 12, and their ends will be grasped by the projections 8 of the husking-rolls 7, and thereby pulled between said rolls and toward a vertical position, gradually working down to the portions of the rolls carrying the nippers 5'). These nippers act to sever the stalks from the ears, and the stalks so severed drop onto the slotted platform 47 and from said platform are conveyed by the conveyer-belt -11 to and between the feed-rolls 35 and 36 and thence through the opening 34 of the cutting and shredding casing and into said casing, where they are acted upon by the knives, which cut and tear the stalks into shreds, and these cut or shredded portions thence pass into the fan-casing, where they are acted upon by the fan and forced up the conduit 24 to the place of delivery. The cars of corn are of course lefton the top surfaces of the husking-rolls and slide down said rolls,but before leaving the rear ends thereof are acted upon by the husking-pins 10, and thereby stripped of their husks, the said husks passing between the rolls and being caughtby the slotted platform 47 and being then conveyed by the conveyor 41 between the feed-rolls 35 and 36 and thence into the cutting and shredding casing, where they are acted upon by the knives, and thence pass into the fan-casing, where the cut and shredded pieces are blown upwardly in the conduit 24. The husked ears pass off the rear ends of the rolls and into a suitable receptacle for receiving the same. If in the operation ofhusking any of the corn should be shelled from the ears and pass between the rolls onto the slotted platform 47, said shelled corn is free to pass through the spaces or openings of said platform and be caught in the funnel 48 and thence out of the discharge-opening 49 thereof and into a suitable receptacle.

From the foregoing description it will be seen that the construction is such that all the principal movable parts or gearing of the machine are arranged compactly at one end thereof and that the main drive-shaft of the machine, upon which are located the cutting mechanism and the fan mechanism, is rotated directly from the engine instead of through the intermediary of gearing or belts. By this arrangement I am enabled to sccuretho greatest power where the greatest strain occurs, and consequently where the greatest power is most needed.

By the provision of the circular saws l 5 and 16, arranged as described, 1 provide for offectually cutting the band or cord of the bundle and at the same time insure the disentanglement or separation of the intertwined stalks after the band thereof is cut.
