AUGUST ROSENTHAL, OF MILWAUKEE, WISCONSIN, ASSIGNORv TO THE ROSENTHAL CORN HUSKING MACHINE COMPANY, OF SAME PLACE.

COMBINED CORN-HUSKER AND FQDDER-SHREDDER.

SPECIFICATION forming part of Letters Patent No. 621,505, dated March 21, 1899.

Application filed November 15,1897. Serial No. 658,535. (No model.)

in combined corn-huskers and fodder-shredders.

The primary object of my invention is to provide an improved construction whereby the cornstalks are adapted to be fed horizontally to the rolls and the stalks carried between the rolls in their horizontal position, leaving theseveral ears remaining on the rolls to be stripped of their husks, thereby effecting a great saving of time, as the stalks can be drawn between the rolls horizontally in a very short period.

An incidental object is the provision of an improved form of feeding device which is simple in construction and adapted to insure the horizontal feeding of the cornstalks and their attached ears.

A still further object contemplated is the provision of improved cutting and crushing mechanism arranged beneath the rolls and adapted for cutting and crushing the detached cornstalks into short strips or slivers for use as fodder. I

Having the above and other objects in View the invention consists of the devices and parts, or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of the invention with parts broken away. Fig. 2 is an end elevation.

Fig. 3 is a cross-section on the line 3-3 of Fig.

1 with the side boards 8 removed, and Fig. 4 is a plan view of the rolls and gearing.

Referring to the drawings, the numeral 5 indicates the base of the frame, 6 6 the rearwardly-inclined front standards, and 7 7 the rear standards. Extending longitudinally of the frame from the front to the rear standards are the side boards 8 8. At the ends of the frame, between the respective standards,

are secured brackets similar to 9, which are formed with bearings for the shafts or end journals of a plurality of rolls. Four of these rolls are shown in the accompanying illustrations of my invention, and said rolls are arranged in sets. The two rolls of one set are indicated by the numerals 1O 10 and the two rolls of the other set by the numerals 11 11". A space is left between the sets of rolls, so that the inner rolls of the sets will clear each other without contacting, while the surfaces of the two rolls of a set are in close proximity, so as to almost contact. The extended journal of one of the rolls carries thereon a gear-wheel 12, andthis gear-wheel is in mesh with a pinion 13, mounted on a main driving-shaft 14. This shaft has mounted fast on its end two band-pulleys 15 and 16, respectively, and a fly-wheel 17 is located thereon between the two pulleys. The outer wide band-pulley 15 is adapted to receive therearound a driving-belt (not shown) leading from any suitable source of power, while the other pulleylG is adapted to receive therearound a crossed belt 18, which belt extends to andaround a band-pulley 19, mounted on a fan-shaft 20, said shaft being journaled in suitable bearings 21 21 and extending into a fan-casing 22. This shaft carries on its inner end, within the casing, a series of wings or blades 23. The perimeter of the casing is provided with an opening 24:, with which a conduit or pipe (not shown) may be connected.

The journals at the rear ends of the rolls have mounted thereon intermeshing gears 25. It is obvious that as the gear-wheel13 is rotated from the main driving-shaft the roller on the journal of which said gear is mounted will be rotated, and its rotation, through the intermeshing gears 25, will be communicated to all of the other several rollers.

- The numeral 26 indicates a short shaft on which is mounted a gear 27, somewhat larger than the gears 25 and meshing with one of the end gears of the series of gears 25. The rotation of this end gear therefore is communicated to the gear 27, and this gear 27 is also in mesh with a gear 28,.mounted' on one end of a shaft 29, the other end of said shaft carrying a grooved pulley 30.

ing portions.

The several rolls employed in connection with my improvements may be-of any desired construction best adapted to perform the functions intended, although the form illustrated in the accompanying drawings is preferred. The front ends of these rollers constitute the receiving ends thereof, while the remaining portions thereof constitute the husk- There are spaces 31 31 between the front receiving portions of the rollers, said spaces extending from the extremities of said rollers inwardly for a desired distance and gradually diminishing in width toward the inner extremities. These front receiving portions of the rollers are provided with longitudinal rows of radially-projecting teeth 32, which rows of teeth alternate with each other longitudinally, the rows of teeth on one roller of one set entering the intermediate spaces axially or longitudinally of the other roller as the rollers revolve. The teeth '32, as the corn is fed to the rollers, take hold of the stalks and carry them between the rollers. The husking portions of the inner rollers 10' and 11' are provided with a number of projecting husking-pins 33 and the outer rollers 10 and 11 with registering recesses 34 to receive said pins as the rollers revolve. The husking portions of the rolls 10 and 11 are also shown as having secured thereto diamond-shaped nippers 35 35, preferably of steel, which nippers preferably extend from the inner ends of the receiving portions of the rollers lengthwise of the husking portions of said rollers for substantially one-half the lengths of said husking portions. The husking portions of the rollers 10 and 11 are also formed with recesses 36 36, which are so located as to receive therein the projecting edges of the'steel nippers as the rollers revolve toward each other. The recesses 36. advisably extend throughout the entire length or substantially the entire length of the husking portions of the rollers 10 and 11.

Mounted in the upper portion of the frame proper of the machine is my improved form of hopper, consisting of the side pieces 37 37 and a front end piece 38, which connects said side pieces. The lower edges of the side pieces 37 fit within longitudinal boards 39, and the lower edges of said side pieces 37 are beveled or inclined rearwardly to correspond to the slant of said boards 39 and with the side boards 8 of the frame and the general declination of the machine from the front to rear, the rollers and other parts of the machine being on a gradual slantrearwardly, as clearly shown inthe drawings. The inclined formation of the side pieces 37 of the hopper of course throws the widest portions of said side pieces toward the rear of the machine. Arranged between and secured to the side pieces 37 at the rear of the hopper is an inclined table 40. The hopper is divided longitudi- 'nally into two divisions by means of an archshaped partition 41, said partition being socured at one end to the inclined table 40 and blades 51.

at its opposite end to the connecting-piece 38. Secured to the top surface of this partition and extending longitudinally thereof is a knife 42. This knife is preferably in the form of a saw-blade, being provided at its upper edge with a series of teeth. The side pieces 37, near their front ends, are provided with elongated slots 43, through which bolts 44 pass and enter the edges of a transverse board 38, forming part of the framework.

Mounted in bearings formed at the upper ends of the standards 7 7 are the ends of a transverse crank-shaft 45, said shaft being formed with two cranks 46 46. Connected to these cranks are arms or pitmen 47 47, which extend forwardly and connect with the side pieces 37 of the hopper, as clearly shown. On one end of the crank-shaft is carried a grooved pulley 48, which is connected up to the pulley 30 by means of a crossed belt 49.

Mounted on the main driving-shaft 14, which is arranged beneath the series of rollers, is a cylinder 50, said cylinder having projecting radially therefrom a series of cutting- Arranged above the cylinder 50 and extending parallel therewith is a beam 52, said beam ha'ving projecting downwardly therefrom a series of fingers 53. The ends of the beam 52 are formed with journals 54 54, which have their hearings in the frame, as clearly shown in Fig. 5. The ends of the beam are also formed with upwardly-extending lugs 55 55. Through these lugs bolts 56 56 pass and enter the framework. As the knife-cylind er revolves the blades thereof are adapted to pass between the fingers 53 of the beam 52. If any hard substance, such asiron and the like, should be caught by the blades of the cylinder and carried around into contact with the fingers 53, the pressure will have a tendency to break the bolts 56 and the moment these bolts are broken the beam 52 is free to turn on its journals, By this provision the strain on the parts occasioned by any hard substance getting into the cutting mechanism is readily compensated for without any serious injury to the machinery.

In the operation of myinvention when the main drive-shaft 14 is rotated rotation is thereby imparted to the several rollers, as hereinbefore' described, and at the same time rotation is'also imparted to the shaft 29 and the grooved pulley 30, carried thereon. The rotation of the grooved pulley 30 is communicated to the crank-shaft by means of the crossed belt 49. As this crank-shaft is rotated a reciprocating movement is imparted to the side pieces 37, constituting the hopper, to the extent permitted by the elongated slots 43, through which the bolts 44 pass. Not only is a reciprocating movement imparted to said hopper, but at the same time the rear end thereof is given an up-and-down movement between the longitudinal inner boards 39. It

will be understood that the movable parts of the hopper are the side pieces 37 thereof, the inclined table 40, the arch-shaped partition 41, and the knife 42, which are all connected together in the manner previously pointed out. The end board 38 is stationary, and the side pieces of the hopper slide against the opposite edges thereof to the extent permitted by the elongated slots. The cornstalks'may be deposited in the hopper tied up in the form of a bundle, and are so placed therein that the ears of corn are toward the rear end of said hopper adjacent to the inclined table 40. The longitudinal reciprocation of the hopper will cause the teeth of the knife to act on the cord and out the same. The bundle will then divide itself into two portions, one portion falling down in the space between one side of the arch-shaped partition and one of the side pieces 37, and the other portion of the bundle will fall into the corresponding space on the opposite side. The inclined table 40 has a tendency to force the cornstalks toward the front end of the machine, and the up-anddown shaking movement imparted to the hopper causes the cornstalks after they pass into the spaces between the arch-shaped partition and the sides of the hopper to arrange themselves properly lengthwise on the rollers. It will be noticed that extending down from the sides of the arch-shaped partition are guards 57 57, which prevent the cornstalks from arranging themselves on thesurfaces of the two inner rollers of the series. The moment the stalks come'in contact with the surfaces of the sets of rollers '10 10 and 11 11' the teeth 32 first engage the stalks and tend to pull them into the spaces between the rollers, in the widest portions of the spaces 31, where they are gradually worked down toward the more narrow portions of said spaces. The nippers 35 35 also come into play as the rollers are revolved. Said nippers during such revolution pass into the recesses 36, and the stalks are thereby necessarily pulled in between the pointsor edges of the nippers and the walls of the recesses, being thereby compelled to make a very short turn. The sharpened edge or point of the nippers then severs the stalks from the ears, and said stalks are carried between and below the rollers. The recesses 36 are preferably continued to the front ends of the rollers, inasmuch as should any portions of the stalk remain on said rollers after the nippers have acted the recesses will more effectually carry the stalks between the rollers and will also carry the husksv between the rollers. The ears of corn 'of course slide down the rollers and are acted upon bythe huskingpins 33, and thereby stripped of theirhusks, said husks being carried between the rollers. The ears of corn finally slide off the rear ends of the rollers into a suitable receptacle.

The cornstalks and husks which pass between the rollers are caught by the knives of the revolving cylinder and carried against the fingers 53 of the beam 52, and are thereby cut up or crushed into short lengths or slivers. These short lengths or slivers are deposited upon inclined platforms 58 and 59,

respectively. Theinc lined platform 58leads downwardly from the rear end of the ma chine to the fan-casin g, and the inclined platform 59 inclines downwardly from the front end of the machine toward the rear, so as to deposit onto the platform 58. The fodder caught by the platform 58 is carried into the nessity of feeding loose cornstalks continuously to the machine and that instead thereof the stalks can be fed in bundles and the tying cords automatically severed and the stalks automatically arranged and deposited lengthwise onto the rolls. It is also apparent from the fact thatthe cornstalks are fed horizontally to the rolls and are carried horizontally between the rolls that an important advantage is gained, as a great saving in time is thereby effected over the more usual way of feeding the stalks vertically or in an approximately vertical line to the rollers, so as to be carried vertically through said rollers.

A further advantage -of my invention resides in the particular form of cutting mechanism whereby damage or breakage of the parts, owing to hard substances getting into the cutting mechanism, is avoided.

While I have herein shown and described four rollers, I do not wish to be understood as limiting myself to that number, inasmuch as it is obvious that, if desired, only two rollers may be employed, with only the necessity of omitting the central partition of the hop: per and decreasing the width of said hopper to some extent. It is, furthermore, evident that more than four rollers may be employed, as the number of sets of rollers may be increased in accordance with the widthand capacity of the machine.

It will of course be understood that the bearings for the journals of the-several rolls are yielding, so as to permit them to spread apart somewhat as the cornstalks are forced therebetween.

What I claim as my invention is.-

1. The combination, of a frame, aset or sets of revoluble rolls mounted therein, a hopper mounted in the upper portion of the frame, said hopper leading to the rolls and adapted to feed the stalks to said rolls, cutting m echanism carried by the hopper, and means for reciprocating the hopper, whereby as the same is reciprocated the cutting mechanism is adaptedto act on and sever the tying-cord of a bundle of stalks.
