CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 782,910, dated February 21, 1905.

Applicationfiled July 1, 1904. Serial No. 214,928.

To all whom it may concern.-

Be it known that I, J OSEF KAURZINsKY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Corn-Husking Machines, of which the following is a specification.

This invention is a machine for husking corn. It is fed by hand and operated by foot-power. It includes means for tearing the husk off of the ear and for breaking the ear from the butt or stalk.

The ear is carried by a sliding holder and forced through a ring containing a number of inwardly-projecting spring hooks or blades which rip the husk therefrom, and after reaching the limit of its movement a lever is caused to swing around against the ear and break the same from the butt, after which the slide retracts, carrying with it the husk, which is then removed and another ear inserted.

The machine is illustrated in the accompanying drawings, in which Figure 1 is a side elevation thereof. Fig. 2 is a top plan view. Fig. 3 is a'vertical section on the line 3 3 of Fig. 1. Fig. 4 is a detail in elevation of thehusking hooks or blades.

Referring specifically to the drawings, 6 indicates the wooden frame of the machine of proper size and formation to support the parts hereinafter described.

7 indicates a slide mounted to move horizontally between guides 8 on each side thereof. The slide is held in place by plates 9 at each end thereof and on the upper and under sides thereof, between the. projecting ends of which plates the edges of the guides 8 are embraced.

At the front end of the slide 7 is a device for gripping and holding the butt of an ear of corn. Said device consists of two brackets -10, which are mounted on the front end of the slide and which carry jaws 11, which have the form of disk-sections spaced slightly apart and having at the center acircular opening or recess therebetween, as indicated. at 12. The butt of the ear is inserted and held within this recess. One of the brackets 10 turns upon a pivot 13, and the jaws or disk-sections are normally forced toward each other by the pressure of a spring 1 1, which presses against the rear end of the pivoted bracket.

The stripper for the husks consists of a ring 15, provided with a plurality of hooked springblades, (indicated at 16,) the points of the hooks being properly positioned to scrape along an ear of corn thrust forward by the sliding holder above described. On the under side the ring also has a number of knives 17, which are so disposed as to slit the husks along the ear as the same is forced through the ring. The knives are slightly in advance of the hooks, as shown in Fig. 1, so that the stripping action will follow the cutting action. The ring is supported by being let into notches in the beams 6, where it is held by bolts The device for breaking off the ears after they are husked consists of a crooked lever 18, which is pivoted at 19 upon one of the side beams and has at each end an upright 20. The lever is operated by a cord 21, which extends over a pulley 22 to connection with a lever 23 below. The return movement of the lever is effected by a spring 24:. The uprights project a sufiicient distance to strike the ear after it shall have passed through the husking-ring, and the lever is so shaped that one upright strikes the car at the front end on one side and the other upright strikes it at the rear end on the other side. WVhen the lever is swung, one 'upright presses one way and the other presses the other, way, and the car is snapped or twisted off of the butt and falls off. The operative means for this device comprises a treadle-lever 25, which is pivoted at 26 and engages at its rear end the lever 23, which is pivoted at 27 upon one of the frames of the machine. The action of the treadle is to cause the lever to pull the cord 21 down and swing the lever 18. The treadle-lever is connected by a link 28 with a bent lever consisting of two arms 29 and 30, by means of which the slide 7 is operated. The arms 29 and 30 are pivoted at 31 and are yieldable with respect to each other by means of their connecting-spring 32, A spring-33, con nected between the frame and the arm 30, acts to return the parts to original position after the treadle is released. The spring 33 is of less strength than the spring 32. The upper end of the arm 30 is connected to the slide 7 by a slot, pin, and antifriction-roller connection, (indicated at 84.)

Figs. 1 and 2 show the parts in partlyadvanced position, that iswith the treadle partly depressed. In operation the slide is normally retracted, and the butt of the ear is inserted between the jaws 11 with the ear extending horizontally therefrom and directed toward the center of the ring 15. By depression of the treadle the slide is advanced and the ear is forced through the ring and between the knives and hooks, which act to cut and rip the husk from the ear as it passes between them. When the slide reaches the limit of its advance, further depression of the treadle causes the spring 32 to yield, and the rear end of the treadle-lever then comes in contact with the under side of the inner arm of the lever 23, lifting the same and pulling down on the cord 21, which swings the lever 18, and by means of the projections 20, as above described, the ear is broken ofl. The treadle is then released and the parts assume their original position, the husk and butt of the ear being withdrawn from the knives by the jaws 11. from which they are removed and another ear inserted for the next operation.

By means of this machine much more rapid work can be done than by the husking implements commonly employed for handwork, and askilled operator will be able to husk several hundred bushels a day, whereas by the hantll implements a hundred bushels is good Vol I.

What I claim as new, and desire to secure by Letters Patent, is

1. In a corn-husker, in combination, a ring of inwardly-projecting blades, means to hold the butt of an ear of corn and force the same through the ring between the blades, and means beyond the blade to break the ear from the butt.

2. In a corn-husker, in combination, a ring of stripping devices, a holder for an ear, slidable to and from the said devices and constructed to force the ear therebetween, a lever behind the said devices having projections arranged to strike the ear and break the same from the butt, and means to operate the holder and lever.

3. In a corn-husker, in combination, aring to this specification in the presence of two subscribing witnesses.
