CORN-HUSKING MACHINE SPECIFICATION forming part of Letters Patent No. 774,863, dated November 15, 1904. Application filed February 18, 1904. Serial No. 194,293. (No model.)

To all whom it may concern.-

Be it known that we, CULLEN BORDEN, residing at Hume, in the county of Edgar and State of Illinois, and JAMES SANFORD BORDEN, residing at Louisville, county of Jefferson, and State of Kentucky, citizens of the United States, have invented a new and useful Corn- Husking Machine, of which the following is a specification.

7 Our invention relates to corn-husking machines that are operated in the field and husk the corn from the standing stalks without cutting them off; and the objects of our improvement are simplicity of construction, ease of operation, comparative inexpensiveness of manufacture, rapidity of operation, efiectiveness, and adaptability to various conditions of the crop to be operated on.

In the accompanying drawings and the following specification will be shown the man ner in which we attain these objects so clearly that any one skilled in the art to which our invention pertains will be able to understand, make, and operate it.

In the drawings, Figure 1 is a Fig. 2, a rear elevation with the poles and steering-wheel cut 01f; Fig. 3,'a rear elevation of the steering-wheel, seat, and adjacent parts; Fig. 4, a side elevation with portions cut awayto show working parts, and Fig. 5 a detailed view of the husking-rollers.

Similar reference-numerals refer to similar a parts throughout the several views of the drawings.

The body of the machine consists of the yoke-shaped frame 1 and the arch 41 at the rear of the frame.

2 and 3 are husking-rollers journaled forwardly in frame 1 and at the rear in arch 41.

5 is the drive-wheel, which is rigidly attached to its axle, and 6 is the wheel on the opposite side of the machine, which is loose on its axle. j

At the sides of the rollers 2 and 3 are side boards 35, extending upward from frame 1. Secured to the front of frame 1 are the noses 20 and 21. At the rear of frame 1 on the rear of arch 41 are lugs 38, in which are secured the poles 23 and 24. On the right-hand plan view;

side of the machine, immediately forward of arch 41, is the elevator 4. On the drivingaxle are secured two sprockets 16 and 34, side by side. A shaft 42 is journaled on arch 41 at its upper part transversely to the rear ends of rollers 2 and 3. This shaft is geared to wheel 16 on the driving-shaft by means of the sprocket-chain 17.

7 and 8 are shafts which form rear extensions of rollers 2 and 3, respectively.

12 and 22 are spur-gears on the rear ends of shafts 7 and 8.

10 is a bevel-gear on shaft 42, which meshes with bevel-gear 11 on shaft 8.

is a small sprocket-wheel on shaft 42, which receives motion from the drivingsprocket 16.

13 is a bevel-gear mounted on the righthand end of shaft 42, and 14 is a bevel-gear meshing with 13.

31 and 32 are sprocket-wheels connected by sprocket-chain 30, by means of which the elevator is driven.

29 represents the elevator buckets or cleats.

18 represents a sprocket secured to the outside of the right-hand side board 35, the shaft ,of'which passes through said side board and transmits motion to a sprocket on the inside of the side board, and this sprocket in turn drives the chain 33, which carries conveyerblades 9.

36 is a cross-piece extending from one of the-side boards to the other and serves for a fastening for spring 37. Spring 37 is made, preferably, of spring-steel and extends backward over rollers 2 and 3. The poles 23 and 24 are secured to the rear part of frame 1 in lugs 38. At the rear end of poles-23 and 24 is secured an arched draft-frame 25. From this frame, which is preferably made of metal, extend the arms 39, to which are secured swingletrees 40 for attaching the horses.

26 is the steering-wheel, and 27 is the hand-- wheel, disposed immediately in front of the seat 28, by which steering-wheel 26 is turned.

It will now be understood that as the machine is pushed along over the row of corn the drive-wheel 5 imparts motion through its axle to the drivingsprocket 16 and this through chain 17 to the small sprocket 15, thus rapidly rotating shaft 42. Shaft 42 imparts motion to bevel-gear 10, which in turn causes bevel-gear 11 and roller 3, secured to it, to rotate, and spur-gear 22, secured on shaft 8, imparts motion to its companion gear 12, and thus causes roller 2 to rotate in the opposite direction, so that the upper surfaces of rollers 2 and 3 run toward each other. Rollers 2 and 3 are provided on their front ends for some distance with deep screwthreads. The threads are so disposed as to oscillate and are so formed as to be deeper in front and become gradually shallower toward the rear and finally run out. The noses 20 and 21 are flared from each other at the forward end, so as to direct stalks of corn between them. They are also inclined downward, so that their points are in proximity to the ground in order to catch down corn and direct it to rollers 2 and 3. It will be understood that thus the stalks of corn are grasped by the threaded portion of the husking- rollers 2 and 3 and fed backward by the threads and at the same time forced downward, and the ears are snapped off the stalks by the time the stalks have reached the point where the threads run out. The cars are now delivered to the conveyer-blades 9, attached to chain 33, and are slowly conveyed backward by them over the remaining portion of said rollers. During this movement the husks are grasped by the oscillating rollers and jerked off. As the ears proceed backward they pass under pressure-spring 37, which insures contact with the rollers, in order that every bit of husk may be removed. \Vhen the ears have passed over the entire length of the rollers 2 and 3, they drop into the space about the shafts 7 and 8 and then into the boot of elevator 4. Here they are received by the buckets or cleats 29 and elevated and may be caught in a wagon that may be driven alongside of the machine for that purpose. The elevator 42 is driven by bevel-gear 13 on shaft 42, which in turn drives bevel-gear 14 and sprocket 32, secured thereto. We prefer to arrange the machine as shown, so that the horses push it in front of them instead of pulling in the usual way. Thus the horses are hitched to the swingletrees 4:0 and may be haltered to the machine in front of them, and instead of driving or guiding by means of lines the operator, seated upon the seat 28, steers the machine by means of wheel 27.

We are aware that corn-husking machines with husking-rollers have been made, and we do not claim the rollers broadly; but,

Vhat we claim as our invention, and desire to secure by Letters Patent, is

1. In a corn-husking machine, the combination of a yoke shaped frame, round and smooth, parallel and approximately horizontal husking-rollers screw-threaded on their forward ends in such a manner that while the threads oscillate throughout their length, the troughs of the threads become shallower from the forward end of the rollers backward until they run out, leaving the rear and greater portion of the rollers without threads, a driving-wheel, and means for transmitting motion from said driving-wheel to said huskingrollers, substantially as specified.

2. In a corn-husking machine, the combination of a yoke-shaped frame, oscillating and approximately horizontally-disposed huskingrollers, rotatably mounted in said yoke-sh aped frame, said husking-rollers screw-threaded on their forward ends so that the threads oscillate throughout their length but run out backward, conveyer-blades mounted on atraveling chain so disposed as to travel longitudinally over said husking-rollera and a pressurespring disposed longitudinally over said husk ing-rollers, substantially as and for the purpose specified.

3. In a corn-husking machine, the combination .of a yoke-shaped frame, a pair of oscillating husking-rollers provided with right and left feeding screw-threads journaled in said yoke-shaped frame, means for imparting rotary motion to said husking-rollers from a drive-wheel, a pressure-spring secured longitudinally over said husking-rollers for pressing the ears of corn firmly into contact with said husking-rollers, conveyer-blades extending transversely across said husking-rollers and so mounted on a traveling chain as to travel longitudinally over said husking-rollers and under said pressure-spring, poles attached to the rear of said frame, an elevator mounted on the rear end of said frame, means for driving said elevator from the drivingshaft of the machine, a steering-wheel at the rear end of said poles, and a hand-wheel for operating said steering-wheel, substantially as and for the purpose specified.
