Application led January 6, 1913. Serial No. 740,362.

To all :whom 'it may concern:

Be 1t known that-I, WmLIAM H. SELLs, a

citizen of the United States', residing at Bufalo, in the county of Erie and State of New York, have invented new and useful Improvements in Corn-Huskers, of which the following is a specification.

This invention relates to a machine for removing the husks from green corn preparatory to cutting the kernels from the cob, such machines being commonly known as corn huskers and employed in canning factories where corn is pac ed on a large scale for the trade. p

One of the objects of this invention is to provide a machine for this purpose which is very compact and has a larger capacity compared with machines heretofore in useA for this purpose and occupying a given amount of space.

Another object of this invention is to provide simple, eflicient and reliable means w'hereby the ears of corn are confined on the respective pair of husking rollers to which the same have been fed and the ears are prevented from turning upon one end which otherwise would cause the corn to be-i come injured and also result in choking the` machine.

In the accompanying drawings consisting of 2 sheets: Figure 1 1s a top plan view of a corn husker embodying my improvements.

- Fig. 2 is a fragmentary vertical transverse section vtaken in line 2-2, Fig. 1, and showing part of the driving mechanism for operating the husking rollers. Fig. 3 is a fragmentary verticaltransverse section, on

an enlarged scale taken in line 3 3, Fig. 2. Fig. 4 is a fragmentary vertical longitudinal section taken in line 4 4, Fig. 1.

Similar characters `of reference indicate corresponding parts throughout the several views.

1 `represents the main frame o1 ne mayarranged so-mewhat higher than the inner roller.

The inner rollers of both pairs are arranged comparatively close together out are separated by a longitudinal division bar having an upright longitudinal web or plate 4 arranged between the opposing peripheral portions of these rollers and a horizontal plate 5 arranged at the upper edge o1 the web and projecting at its opposite longitudinal edges over the adjacent parts of the inner husking rollers, as shown in Fig. 3. This bar is stationary and may be Supported at its opposite ends in amT suitable manner on the adjacent part of the main frame. The husking rollers of each pair are caused to turn together so that their opposing sides move downwardly, this being preferably effected by means of coperating gear wheels 6 secured to the front ends of the shafts of the husking rollers of each pair. Motion is transmitted to the two pairs of husking rollers from the main driving shaft 7 of the machine by means of a main gear wheel 8 secured to the driving shaft, an intermediate gear wheel 9 engaging with the driving gear wheel 8 and two intermeshing gear wheels 10, which are secured respectively to the front ends of the shafts of the inner husking rollers and one of which meshes' with the intermediate gear wheel 9, as shown in Figs. 1, 2 and 4.

The ears of corn to be husked may be fed upon the front end of the two pairs of husking rollers by feeding deviceswhich may be constructed in any suitable manner but which are` preferably constructed as follows: The feeding device shown in the drawings comprise two endless conveyers which are arranged on opposite sides of the ma- Vchine at the front ends of the pairs of husking rollers, each conveyer being adapted to vfeed the ears of corn laterally from one side around a. plurality of receiving sprocket wheels 12 mounted on the main frame while their delivery portions pass around dellvery sprocket wheels 13 mounted on a shaft 14 journaled in the adjacent part of .the mam frame. This last mentioned shaft may be turned in the direction of the arrow by any suitable meansfor causing the upper operative stretch or the endless conveyer to move inwardly or forwardly toward the companion pair of husking rollers. The operator places the ears upon the conveyer so that the butt ends thereof project forwar'dly into engagement with a longitudinal gage lmounted on the adjacent part of the main frame and as the upper stretch of the conveyer moves forwardly it carries theears along with it by means of wings or flights 16 mounted on the conveyer belts and engaging with the ears.

Before the ears reach the inner or delivery turn of the conveyer belts the butt ends thereof are trimmed off'so as to facilitate the subsequent removal of the husks from the ears. This trimming device consists preferably of a pair of cutters or blades 17, 18 mounted one above the other on the main frame and having their shearing edges arranged to form a V'shaped mouth. As the ears of corn are moved forwardly by the conveyer the butt ends thereofengage with the inwardly converging cutting edges of the i blades whereby the'butts of the ears are severed from the body and the husks on the adjacent parts of the ears are loosened. While the ears are thus engaged by the trimming device the same are held down upon the conveyer and prevented from becoming displaced by means of holding springs 19 which are mounted at their outer ends on a supporting bar 20 mounted' on the frame above the path of the ears of corn. The upper portions of the delivery sprocket wheels are arranged somewhat higher than the front ends of the companion pair of husking rollers and as the conveyer moves downwardly around the inner or delivery sprocket wheels the ears of corn are discharged from the conveyer and guided into the bight between the adjacent pair of husking rollers at the front ends thereof by a guiding device which is preferably composed of a plurality of inclined guide bars 21 extending from the delivery portion of the conveyer downwardly and inwardly to the upper part of the adjacent outer husking roller at the front end thereof. As the ears of corn are moving inwardly over the guide bars 21 to the companion husking rollers the same are prevented from rising unduly and becoming displaced by a plurality of pairs of presser bars 22 arranged lengthwise over the delivery portion of the conveyer and transversely over the receiving portion of the respective husking rollers and mounted at their outer ends on the adjacent support- -ing bar 2O carried by the frame while their inner ends rest upon a longitudinal shelf 23 arranged adjacent to the front end of the husking rollers. Two operators are able in this manner to feed the machine from opposite sides thereof, the ears of corn fed by one operator being delivered to one of the pairs of husking rollers and the ears of corn fed by the otheroperator being delivered to the other pair of husking rollers.

As each ear of corn is presented to bthe upper sides of a pair of husking rollers the opposing surfaces of these rollers during their downward movement grip the husks and pull them from the ears and discharge the husks downwardly on the underside of these rollers. In order to clear the receiving or front ends of the pairs of husking rollers so as to make room for the subsequent ears fed to the same and also to insure complete removal of all of the husks .from the ears the latter are moved from the front ends of the husking rollers lengthwise of the latter and then discharged in a. completely husked condition from the rear ends of these rollers. During .its passage lengthwise over the husking rollers each of the ears is turned more or less and all parts of its periphery are eX- posed to the stripping action of the husking rollers so as to eifectually remove all the husks and silks from theear before it escapes from these rollers.

The longitudinal movement of the ears over the husking 'rollers is preferably effected by a clearing conveyer mechanism which is so constructed that it serves the purpose of moving the ears of corn lengthwise over both pairs of husking rollers. In its preferred form 'this clearing conveyer comprises an endless belt 24 arranged lengthwise over the space between the two inner husking rollers and passing at itsfront and rear turns around front and rear sprocket .

wheels

25,26 mounted on the main frame of the machine, and propelling wings or liights 27 .secured transversely to the clearing conveyer belt so that upon turning the sprocket wheels in a direction for causing the lower stretch of the belt 24 to move from the front ends of the husking rollers to the rear ends thereof its propelling wings -will move through the channels formed on the upper sides of the two pairs of husking rollers and push the ears of corn resting thereon from the front ends to the rear ends thereof. As the ears drop from the rear ends of the husking rollers they may be received by a suitable receptacle provided for this purpose or dis-- facilitating the husking operation, a cleaning device is provided which preferably comprises a plurality of rotatable cleaning brushes 3l one of which engages the underside of each husking roller, as shown in Fig. 3. l v

In order to prevent ears of corn which are fed upon the front end of one pair of husking rollers from accidentally getting over on the front end of the other pair of husking rollers and also to prevent the ears of corn from being drawn endwise between the rollers at the front part of the latter retaining means are provided which are preferably constructed as follows: Above the front end of each inner husking `roller is arranged a retainin arm 32 which is pivoted at its front end y means of a horizontal transverse in 33 on a bracket 34 supported on the adjacent part of the main frame so that its rear part is capable of swinging vertically toward and from the adjacent upper side of the respective husking rollers. The rear part of this arm is of angular form in cross sectionand comprises an inner upright stop wall 35 and an upper horizontal cover or plate 36 which projects outwardly from the upper edge of the stop wall so as to overhang the respective inner husking roller but stop short of the companion outer roller so as lto form a gap or passageway between this cover plate and the outer husking roller through which the ears of corn may pass laterally from the feeding conveyer to the front pair of the husking rollers and underneath the top plate of the retainin arm. This retaining arm is yieldingly hel in its lowermost p0- sition preferably by means of a spring 37 surrounding the pivot 33 and bearing at one end against the retainin arm and at its other end against the racket 34. The downward movement of this arm is limited by engagement of the lower edge of the vertical wall 35 with the adjacent upper side of the division bar 4, 5, as shown in Fig. 3. The cover plate is arranged suiiiciently close to the upper side of the husking rollers so that an ear of corn which is fed upon the front ends of these rollersand under the retaining arm will be forced into the gripping portion of the huskin members by the arm and also will be held y this arm in a horizontal position lengthwise of the husking rollers and prevented from turning vertically so as to stand on one of its ends, thereby insuring a firm grip of the husking rollers on the husks along the entire length of the ear for quickly and thoroughly removing the husks therefrom and also preventing the husking rollers from becoming choked or clogged as well as preventing injury to the kernels on the ear of corn. The front end of the vertical wall of the retaining arm is beveled or inclined, as shown at 38 in Fig. 4, so that when a Hight or wing of the clearing belt passes forwardly over the husking rollers for carrying the ears lengthwise thereof this wing engages with the inclined face of the retaining arm and lifts the same from its lowered normal positio-n, indicated byfull lines in `Fig. 4, to the elevated position, shown by dotted lines in the same figure, and retains this arm in this position until the wing has cleared the rear end of this arm, after which the latter again drops by gravity aided by the spring 37 into its normal lowered position preparatory to receiving the next following ear from the feeding mechanism.

Normally the retaining arm is depressed-- and holds an ear of corn against the husking rollers at the bight or pass between the same. As the next following wing of the clearing belt passes forwardly underneath the retaining arm this wing lifts the retaining arm and carries the respective ear forwardly from underneath the retaining arm. Just before the clearing wing passes forwardlybeyond the retainingnrm and while the latter is still held in an elevated position by the respective wing the next following wing of the feeding belt delivers an ear of corn under the retaining arm and then the latter is released by the previous clearing wing and permitted to descend and press the next following ear of corn into close contact with the gripping surfaces of the husking rollers.

While the retaining arm is depressed no ear can be fed laterally from the feed belt upon the husking rollers and under the retaining arm inasmuch as the latter at this time is too close to the rollers. To avoid feeding an ear of corn to the rollers when the retaining arm is depressed the movement of the ear feeding and clearing belts is so timed that an ear of corn is fed by the feeding belt to the rollers immediately after a clearing wing has carried an ear forwardly out of the path of the incoming ear and before the retaining arm has dropped to its normal depressed position.

My improved corn husking machine not only permits of removing the husks and silks expeditiously from the ears without injuring the kernels or clogging the machine, but the same is also very simple and compact in construction, not liable to get out of order and all parts are readily accessible for inspection, adjustment and repairs.
