OF SAME PLACE.

CORN-HUSKER' AND STALK-CUTTER.

SPECIFICATION forming part of Letters Patent No. 589,782, dated September '7', 1897.

Application filed March 1O 1896. Serial No 582,535. (No model.)

1'0 ail whom it may concern:

Be it known that I, GEORGE C. 'JANNEY, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and use ful Improvements in Corn-Huskers and Stalk- Outters, of which the following is a specification.

My invention relates to improvements in corn-huskers and stalk-cutters, and it especially relates to improvements in machines such as described in my pending application, Serial NOpSGhDSO, filed September 9, 1805.

My invention consists in the constructions and combinations of parts hereinafter described, and set forth in the claims,

In the accompanying drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a similar elevation taken from the opposite side. Fig. 3 is a side elevation showing details of the adjustingmechanism for the feeding-rolls. Figs. 4 and 5 respectively a plan and end view of a portion of the frame and supporting devices therefor. Fig. 8 is a detail of the same. Fig. 9 is a perspective view showing the folding table. 10 is a detail view of the hinge for the same. Fig. 11 is a sectional view showing the feeding-rolls and the driving mechanism therefor, some of the frame parts being omitted. 12 is an end view of the driving-gears for the feeding-rolls. Fig. 13 is a sectional yiew of one of the feedingrolls. Fig. 14: is adiagrammatic view showin g the construction of the peripheries of the feeding-rolls. Fig. 15 is a detail view of the casing for the bushing-rolls. Figs. 16 and 17 are detail views of the clutch device forming a part of the driving mechanism. Fig. 18 is a sectional view of adetail of the driving mechanism of the feeding-rolls.

Like parts are represented by similar letters of reference in the several views;

In the said drawings, (t represents the main frame, which consists of auxiliary frames a a joined together by supportingposts a.

I) is the cutter-shaft, any ordinary cutter being employed thereon and inclosed within the casing bsuch, for instance, as shown in my prior application.

Figs. (3 and 7 are The power to drive the machine is preferably applied to the cutter-shaft?) through the agency of a pulley b a fly-wheel 19 being preferably employed on said shaft. The

suitable bearings on the lower auxiliary frame a. The shaft 1) has a sprocket-wheel 5 over which passes a chain b, which communicates power to a sprocket-wheel c, which is preferably attached to or formed integral with a gear 0 on a transverse shaft 0 The gear 0 meshes withaspur-gear (Z on one of the feeding-rolls d, the other feeding-roll (1 being geared to the feeding-roll d by rabbitea-red gears m m. The transverse shaft c" drivesv the hashing-rolls, which are located between the frames a a in the manner substantially as set forth'in my prior application referred to, said rolls being inclosed by a casing 6, having as a part thereof a hinged door 6, by means of which access is aiforded 7 5 to the husking-rolls and to the conveyor under the same.

The sprocketwheel 11 which drives the feeding or snapping rolls (1' (2- as well as the 11 usk ing-rolls, is j ourn aled loosely on the shaft b but is adapted to be connected to said shaft, so as to revolve therewith, through the agency of a sliding clutch-collar b which has the usual clutch projections adapted to engage with similar clutch projections on the hub of the sprocket-wheel b the sprocketwheel 19 being held against lateral movement on said shaft by a stationary bifurcated arm I), attached to the frame and adapted to en gage in a groove b in the hub of the sprocketwheel. The clutch-collar D has a peripheral groove in which engages the end of a crankarm U on the end of a rock-shaft b, the opposite end of which is provided with a footlever 19 having connected thereto aspring 5 I), this spring being so applied that it normally holds the clutch 19 out of engagement with the sprocket-wheel U The footlever I) is located near the point where the operator stands, and while the machine is in operation the operator keeps his foot on the lever Z1 and thus throws the feeding and snapping rolls into operation. The moment, however, the foot-lever is released the spring acts to disengage the driving mechanism of the snapping and husking rolls, so that they are instantly stopped. This construction is very desirable, as it enables the operator to immediately stop either the snapping or husking rolls and thus prevent serious accidents, which would endanger the machine or the operator.

lV'hile the above construction is desirable, it is also desirable. that means be employed for operating the snapping and feeding rolls d (1 while the mechanism connected with the husking of the corn be allowed to rest, in case, for instance, it is desired to cut up stalks or fodder from which the corn has already been stripped or husked, in which case the feeding-rolls d (1 together with the conveyers and elevators, should be allowed to run while the husking devices remain at rest. To provide for this, I mount the sprocket-wheel c and its connected gear 0 loosely on the shaft 0 and hold the same against lateral moveme at by a stationary bifurcated arm 0 which engages in a peripheral groove 0 in the hub of said gear. The gear is provided on the end with a clutchface adapted to be engaged by a sliding clutch-collar c, which is connected to the shaft c" by a spline c and a set screw 0 The spline causes the collar to revolve with the shaft, while the set-screw 0 by engaging in depressions c 0 in the shaft, is adapted to hold the clutch either out of or in engagement with the sprocket-wheel hub and thus cause the shaft to revolve with or be disengaged from said sprocket-wheel. The result of this construction is that by disengaging the clutch-collar c the husking devices will remain at rest, while'the feedingrolls (1 (1 will continue to revolve for feeding the stalks to the cutter, and this disengagement takes place without in any way interfering with the operation of the clutch Z2 which will enable the operator to stop and start the husking-rolls at will, as before. As in my former application referred to, I employ vibrating bars 0 which are connected to a crank-shaft 0 above the husking-rolls to assist in feeding and husking the corn. In order that this auxiliary huskin-g device may operate when the husking-rolls are in motion and cease when the husking-rolls stop, I provide on the end of the shaft 0 a sprocketwheel o from which a chain 0 drives a sprocket-wheel c on the crank-shaft 0 By this arrangement the vibrating arms derive their motion from the same source as the huskingrollsthat is, the transverse shaft 0 and when said shaft stops the vibrating devices stop. 7

All the elevators and conveyers receive their motion from the same sourceviz., the

transverse shaft b which is belted to the cutter-shaft b. The conveyers therefore run whenever the cutter runs, unless the belt should be displaced. The conveyer 6 under theluisking-rolls, and the elevating-conveyer f, which carries the husks and stalks from the conveyer 6 are driven by a single endless chain a from a sprocket-wheel e on the shaft If. This sprocket-chain 6 passes over a loose sprocket e thence over a sprocketwheel 6 to the end of the conveyer c and, by the aid of tighteners 6 6 passes around the sprocket-wheel e on the conveyer f. The corn conveyor or elevator f is run direct from the shaftb through the medium of a sprocketwheel f and chain f which passes over sprocketwvheel f connected to the driving mechanism of the conveyer f.

The stalks are fed in the usual way from a table 9 into the feeding or snapping rolls (Z (Z To provide for transportation,I form this table so as to fold into small compass, making the constructions, such that the table is hinged so that it may be readily raised orlowered to obtain access to the husking devices, which are underneath the same. To accomplish this,the table is formed in two main parts g g, one of which is raised slightly above the other, the lower part being provided with side pieces g and the other part 9 having its floor-level on a line with said side pieces, the part 9 being also provided with an up wardly-extending side Each of the parts g and g are further provided with auxiliary hinged portions g githe part g having hinged thereto an intermediate piece 9 which when in operative position forms a continuation of the side 9 of the lower main portion. These auxiliary parts 9 g are hinged to the main parts 9 and g by bars g and g each of which are hinged at g to the respective parts to which they are attached. These hinged points stand considerably back of the ends of the table and are adapted to rest on top of the table, but are bent downwardly and out wardly, so as to extend under the bottoms of the auxiliary portions, so as to firmly brace and support said auxiliary parts. The parts g and g are each hinged to standards 72 which extend upwardly from the frame to a point above or coincident with the top of the side pieces g These standards it are T-shaped and have oppositely-extending trunnions h 72.2, on which are journaled hinged bars 71 7r of the respective tables g g. The result of this construction is that each of the main tables or table parts 9 and g are hinged independently, so that either may be turned to ward the other.

The part 9 may be folded down on the part g, so as to place them within small compass, and when so folded the part g may still be raised on its hinges so as to afford access to the husking-rolls, or the part 9 may be raised or lowered,as desired,on its hinged connection without interfering with the part g.

In folding the parts the intermediate piece g is folded onto the table extension 9 Then each of the table extensions 9 g are turned back on their hinged connections, so as to lie substantially parallel over the respective tag scarce a parts 5 g to which they belong. Then the part g is folded over onto the part g, thus bringing all the parts within small compass,

, ceeding row, and the spaces between the same are formed into concave pocketsj, which are substantially circular in outline and concave in cross-section, so that a depression or pocket is formed in front of each projection. The result of this construction is that when the butt-end of the stalk is placed between the feed or stripping rolls it is allowed to enter the recesses or pockets immediately preceding the projections, and is thus more readily seized by the feeding-rolls and drawn between the same.

As before siated,the fceding'rolls are geared together by rabbit-cared gears that is to say, they have elongated teeth of large pitch, as shown in Fig. 12-so that while the rolls may be separated more or less they are still in gear one with the other. These teeth I arrange at opposite ends of the rolls, as shown at m and on, and I place the teeth at one end opposite the spaces between the teeth at the other end, so that the effect in driving is substantially the same as if the teeth were made of the same pitch, the gears at opposite ends of the rolls coming successfully in operation. Another result of this construction is that if one end of the rolls should be raised to such an extent that the teeth at this end are thrown out of mesh the teeth at the other end would still serve to drive the rolls and also insure the proper meshing of the teeth at the other end when the rolls return to their normal orproper position. It sometimes happens that one end of the rolls will be raised to this extent, and if the driving mechanism is applied all at one end there is nothing to insure the proper meshing of the teeth when they return to their normal position; but it rarely ever happens that the rolls would be so widely separated at both ends, and by dividing the driving-gears in the manner described a continuone and uniform operation of the feedin g-rolls is insured.

The feeding or stripping rolls cl cl are journaled in the usual manner in suitable boxes 0, which are arranged in slotted openings 0 in the side of the frame. The bearings 0 have at the top springs 0 which rest in a suitable support at the lower end of plunger 0", the upper end of which is convex and fits in a concave depression in a pivoted lever 0 which is pivoted between suitable lugso on the frame. This lever is slotted at the other end to reoeive'a rod 0' which is screwt-hreaded at its upper end and has a hand-wheel 0 which bears against the interposed spring 0, between said wheel and the pivoted lever. The rod 0' is bifurcated at the lower end and pivoted to a lug 0 on the frame. The result of this construction is that the tension on the feeding-rolls may be readily adjusted, and by the use of the two springs o and o a more elastic connection is formed, while the lever arrangement having the slotted opening permits the rod 0 to be disconnected therefrom, and by throwing the lever back the plunger 0 may be withdrawn, so as to readily remove the feeding-rolls.

Toprovide for holding the frame in proper position and leveling the operating parts from the main axle, I provide on the front axle p (which is connect-ed to the frame by a balland socket joint 1)) sliding supports 13 These supports 19 have upwardly-extending slotted bracket-armspiwhich are serrated on one side and adapted to engage with extensions 19 which fit under the frame. The result of this construction is that the frame may be readily leveled up on the axle 1), so as to cause the operating parts to stand in proper position by adjusting the supports to the proper position, the two parts 12 1? being connected together in the usual way byclamping-bolts 1). By this construction the frame may stand at an angle to the axle and yet be connected rigidly thereto when the machine is ready for operation. 'When hauling the machine from place to place, these supports will be removed, so as to allow the axle to adjust itself to the inequalities of the road in the proper manner.

Having thus described my claim 1. In amachine, such as described, feedingrolls having engaging project-ions on the peripheries thereof, said projections being arranged in longitudinal and circumferential rows, and interposed pockets or recesses on the peripheries of said rolls and between said projections, said pockets being formed concave at the bottom, substantiallyas specified.
