GORN-HUSKING MACHINE.

Specification of Letters Patent.

Patented Feb.1'7,19l4c.

Application filed March 6, 1907. Serial No. 360,803.

To all whom it may concern:

Be it known that I, GEORGE L. VVAoKnnow, a citizen of the United States, residing at Mellette, county of Spink, and State of South Dakota, have invented new and use: ful Improvements in Corn-Husking Machines, of which the following is a specification.

My invention relates to improvements in corn husking machines with especial refer ence to that class of machines shown and described in my prior Patent Number 7 61,562 dated May 31st, 190 in which the ears are stripped from the standing stalks, husked and delivered as the machine is propelled through the field or along the row.

The object of this invention is to improve the machine disclosed in said prior patent, by increasing the efficiency of the snapping rollers both for removing the ears and for delivering them to the conveyer, also to provide improved stalk gathering mechanism.

My invention also relates to certain structural improvements in the-machine the object of which will be fully apparent from the description.

In the following description reference is had to the accompanying drawings in which Figure l is a front elevation of my invention. Fig. 2 is a side elevation with a portion of the gathering casing and ear elevator casing broken away. Fig. 3 is a plan view with the casing of the gatherers removed'except the lower frame bars. Fig. 4t is an end view of the husking rollers, with the conveyers, and showing portions of the frame in section. Fig. 5 is a detail cross sectional view of the snapping rollers illustrating their relation to the ear receiving shield and conveyer, with arrows showing the line of travel. Fig. 6'is a detail View of the snapping rollers and their supports. Fig. 7 is a top view of the snapping rollers on section line 7% of Fig. 6 showing the yielding adjustable bearing for the outer roller. Fig. 8 is a detail view, showing the snapping rollers in section on a plane cut.- ting their middle portions. Fig. 9 is a detail plan view of the snapping'rollers, and the ear receiving shield and conveyer.

Like parts are identified by the same reference characters throughout the several views.

In the construction illustrated, themachine is arranged to be drawn by horses. Other power may of course be employed. The mechanism is driven from the bull wheels ,1 through the rotary axle 2, and these wheels principally support the weight of the machine, steering wheels 4 being preferably employed, however, to receive suflicient weight to prevent the machine from tilting backwardly without downward pressure on the tongue 5. s

As the machine is drawn forwardly the stalks are receivedbetween the gathering members 6 and 7 which preferably comprise hollow, forwardly and divergently pointed casings having a stalk passage between them leading backwardly to the snapping

rollers

9 and 10 which rollers are inclined laterally from the lower portion of the stalk passage. The inner faces of the gathering members are inclined laterally from the lower to the upper portions in correspondence with the lateral inclination of the snapping rollers, so that the upper portions of the stalks in the passage are bent laterallyinto alinement with the snapping rollers. Gathering belts or chains 11, 12, and 69 are arranged to run backwardly in the stalk passage along the inner faces of the members 6 and 7 and are provided with fingers 18 which catch the stalks and facilitate bending and delivering them to the rollers. The chains may be run ,at a speed somewhat greater than that of the travel of the machine, so as to pick up forwardly inclined stalks and bend them rearwardly toward the snapping rollers in addition to the lateral movement. In the drawings, one chain is illustrated for gathering member 7 and two for the member 6.

.It will be understood, however, that any desired number ,of chains may be employed.

The member 6 is sulficiently short to not interfere with the detached ears when dropping. to the conveyer.

14 and 15 are the chain driving sprockets and 16 are idler guide sprockets. It will be observed (Fig. 3) that at C the inner side, near their forward ends these gathering chains substantially coincide with the sides of the base portion of the gathering members, and then extend at an angle to'the stalk passage in the base portion, and in the direction of the snapping rollers, the chains following the surfaces of the upper portions of the members 6 and 7. The idler pulleys are located within the members 6 and 7, with one side exposed to receive the chains as best illustrated in Fig. 1. The chains preferably have an upward and rearward inclination.

The snapping

rollers

9 and 10 are preferably provided with spiral grooves which extend around the rollers from the bottom to the top in the opposite direction from that of roller rotation, whereby the stalks are lifted with a screw motion. The roller 9 is also located a little in advance of the roller 10 so that the rollers face at an angle to the line of travel of the machine and the stalks pass between the rollers in an angular direction and backwardly toward the line of the row. The detached ears are dis charged in the opposite direction upon the conveyer 22 or upon an inclined shield 23, down which they pass to such conveyer. It will thus be observed that the stalks are not only bent laterally in the stalk passage, but are delivered by the gathering members and conveyer chains to the right of the rollers, and pass between them during their backward and left hand movement, on their return to an upright position.

The right hand roller 10 is journaled in

stationary bearings

24 and 25. The left hand or outer and upper roller 9 is journaled in

bearings

26 and 27, which are in turn supported by the arms 28 of hell cranks, the other arms 29 of which are cushioned against

springs

30 and 31 respectively, these springs being arranged to resiliently resist a separating movement of roller 9 from roller 10. Threaded rods 33 and 34 and nuts 35 are employed to adjust the tension, and the rod 34 is preferably passed through a supporting bracket 38 and provided with a counter-acting spring 39 (see Fig. 8) which cushions the return movement of the roller after the passage of the stalks. One husking roller in each set is similarly mounted upon bell cranks 47 having spring tension connections 48 with the frame (see Fig. 4).

The conveyer 22 is of an ordinary type comprising a series of slats, the ends of which are secured to side chains or belts, the ears of corn being pushed by the slats upwardly along the inclined platform 40 and delivered into a passage way 41 along which they are raked by a similar conveyer 43 to the husking rollers 44. These husking rollers may be of any ordinary construction. The cars are preferably delivered from them to an elevating conveyer 45 which is adapted to deliver them to a wagon or other receptacle.

Any convenient motion transmitting con nections may be employed as illustrated, motion is transmitted from the bull wheel axle shaft- 2 to a counter shaft through the sprocket wheel 51, chain 52 and sprocket wheel 53. (Fig. 3.) The counter shaft drives the snapping

rollers

9 and 10 through the sprocket wheel 54, chain 55, sprocket wheel 56, shaft 57, lever gear wheels 58 and 59 (Fig. 2) and the end trunnion 60- of the roller 10. The two

rollers

9 and 10 are geared together by gear wheels 61 and 62. The gathering chains 11 and 12 are driven from the shaft 57 through the bevel gear wheels 63 and 64 (Fig. 2) sprocket chain 65 and the knuckle jointed shafts 66 and 67 respectively, connected with the driving sprockets 14 and 15. An auxiliary gathering chain 69 on the gathering member 6 is preferably employed and driven by the knuckle jointed shaft 70. The counter shaft 5 drives the husking rollers 44 (Fig. 3) through the sprocket wheel 75, chain 76, sprocket wheel 77, shaft 78 and the bevel gear wheels 79 and 80, of which there are two sets, the husking rollers being in pairs and one husking roller of each pair being directly driven. Motion is communicated to the other rollers of each pair through the gear wheels 81 and 82. The shaft 84 of one of the husking rollers is extended and drives the initial ear conveyer 22 through the sprocket wheel 87, chain 88, sprocket wheel 89 and shaft 90 up on which the conveyer sprockets 91 are mounted. The raking conveyer 43 is actuated from the countershaft 5 through the sprocket wheel 93 (Fig. 2) chain 94, wheel 95 and shaft 96, the latter carrying the driving sprockets 97 of this conveyer. The elevating conveyer 45 for final ear delivery is driven from a shaft 98 of one of the husking rollers through gear wheels 99 and 100 and the shaft 101 which carries the driving sprockets 102 of this conveyer.

It will be observed that the gathering members each comprise a shell or casing within which the gathering chains travel on the return side, and that these gathering members, together with the wall 105 of the machine frame and the inclined shield form a housing which effectually prevents the escape of the detached cars since the outer and upper snapping roller 9 is located somewhat in advance of the roller 10, the two rollers being thus made to face angularly in the direction of the conveyer and the space housed in by the gathering members. The wall 105 and shield 23, with the snapping rollers in this angular based position, the ears are thrown laterally and caught by this housing or by the conveyers, instead of being propelled along the line of the passage between the gathering members. It may be even possible to dispense with the lateral inclination of the snapping rollers, by thus facing the rollers laterally and housing in the space around the conveyer. The

spiral corrugations in the snapping rollers are also serviceable in this connection, since they lift the stalks, and the ears are thrown farther than where smooth rollers are used. A tension rod 107, formed in sections, hav- 111g screw threaded connection with each other, is used to adjust the belt tightener sprocket Wheel 108.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

In a portable corn harvesting machine, the combination of a set of snapping rollers having a downward, forward and lateral inclination, and a set of gathering members forming a stalk passage leading to the snapping rollers and having the upper rear portions of their opposing faces inclined laterally in correspondence with the inclination of said roller; and ear receiving devices extending in front of the upper portions of the snapping rollers which extend to one side of the base portion of the stalk passage, the outer snapping roller being located sufficiently in advance of the other one to deliver ears of corn laterally fromthe stalk passage to permit them to drop by gravity on to the conveyer.

In testimony whereof I affix my signature in the presence of two witnesses.

GEORGE L. WAGKEROW.
