srEcIrrcA rIonformin part of Letters Patent No. 605,122, dated-June 7, 1898. Application filed Januar 13, 1896 Serial No. 576.020. (NoniodeL) To all tohom it concern:

Be it known that I, JOHN H. NEWELL, a citizen of the United States, residing at Urbana,

in the county of Ohampaign and- State of Ohio, have invented, certain new and useful I mprovements in Corn-Harvesters, of which the following is a specification.

4 My invention relates "to "improvements in corn-harvesters and it particularly relates to improvements on the 'corn-harvest'er shown and described in my prior Letters Patent, No. 530,493, dated December i, 1894. v

' The object of the improvements and in What they consist will appear from the following description and from the claims which are joined thereto.

- In the accompanying drawings, which form a part of this specification, Figure 1 is a plan view of a device embodying my invention, a, portion of the'apron or platform being broken away. Fig. 2 is a side elevation of the'same, Fig. 2 being in effect a portion of Fig. 2, illustrated as broken off from the rear end and set up to a different position on the sheet, as

indicated by the arrows. Fig. 3 is a rearfeletial plan view showing the arrangement of the cutting apparatus and the packers and portions of the mechanism for driving and operating the same. Figs. Band 9 are re: spectively sectional elevations showing portions of the same from difie'rent sides. Like parts are represented by'similar letters of reference in the several views. I I

In the said drawings, aa represent the main frame, which is supported "on driving and carrying wheels at. There is supported onthe' main frame a platform 19, secured to one side of which there is an abutment b, which-[rises vertically from the platform, the

- platform I) being connected with and forming a continuation of an apron D which may be of any suitable construction and adapted to move over suitable sprocket-wheels by'the aid of driving and supporting chains b subshown in Figs. 8 and 9.

stantially as set forth in my prior patent referred to.

, The cutting-knives c are stationary and are the same as employed in my prior patent. The "cutting-knives arear'ranged between horizontal guides c" c which f extend outwardly in front of the knives and which supportvertical shafts c 0 arranged in pairs, each pair being supported on opposite sides of the throat formed by the guides 0 c -These shafts c and 0 each carry a series of radial arms 0 c, which are adapted as the shafts are revolved to cross each other, with the angle of their cross at the center of the throat leading to the stationary knives. The power to drive the respective'shafts c and c and their arms is conveyed from the respective driving-wheels through the aid of driving-chains a which, through the agency of suitable sprocket-wheels, transmit motion to short shafts a arranged in the front portion of the machine. These short shafts are each provided with beveled gears a, which mesh with similargears on the vertical shafts 0 From the shafts 0 the motion is transmitted to the shafts c 6* through the agency of driv- Qing chains a a", which pass over suitable sprocket-wheels 011 the respective shafts, as The shafts are all driven at the same speed, so that the radial arms which gather in the stalks and carry them to the cutters always cross each other at the same angle at their meeting-point. The arms 0 are made slightly longerthan the arms 0 so that they cross each'pther and cross thearmsc i jiist, as ,the arms "0 on the respective shafts begin'to separate. On each ofthe shafts c I have shown but one set of arms of, whichare placed low down and'serve to support and gather in the stalksas the machine advances. V are each provided with twosets, which sup- The shafts c, -howe ver,

port the corn at different points intli'eheights of the stalks and carry thembackwardlyduring the time and after the same has been severed. The result of this constrilction and arrangement of the gathering-arm's is such that each stalk or set of stalks is supported constantly by a moving wall formed by the crossed arms, which move backwardly toward the knives at the same speed the machine advances forwardly. Each of the shafts c which stands opposite the heel of the knife 0 is also further provided immediately above said knife with a sta 'hcel 0 having alternate series of teeth and recesses, which as the shaft rotates cross the edge of the knife at the heel in contact with any stalks which have not been completely severed before reaching this point and crowds said stalks directly in contact with said knife, so as to completely sever the same. The shafts c are also provided with a series of arms 0", adapted to cross each other in a similar manner; but instead of being radial throughout their lengths these arms are formed with curved extensions c. These extensions are formed at their outer ends substantially concentric to the shaft 0 and while the shafts are placed at such distance apart that the radial portions of the arms cross each other and serve to advance the severed stalks the concentric portions are adapted as they leave the stalks to press them backward] y onto the apron and against the abutment, which is moved forwardly to receive them in the manner set forth in my prior patent.

To provide for gathering down stalks, I employ on the forward ends of the projecting guides c and c pivoted elevating-fingers (Z. These each consist,preferablypf a single piece of round metal, which is secured to a short shaft or spindle (7 journaled in the end of the guiding projection c and 0 the other portion of the said linger being bent upwardly and baekwardly on the arc of a circle, so as to pass through the said guides substantially concentric to the pin or spindle (Z. An arm (I? is connected to said spindle, and to this arm is connected a link or rod (1, the other end of which is attached to an arm (1 on a shaft (Z which carries at one end an operating-lever (1, having the usual spring-latch and segment to hold it in different positions of adjustment. The shaft (1 projects through the guides c and 0 under the respective knives 0, so that all the fingers are operating simultaneously as the shaft is rotated.

Arranged above each of the guides and c at the rear and adapted to project backwardly slightly over the apron Z) are butters e and 0'. These butters are adapted to slide horizontally in guides c on top of the guides c 0 They are each provided with slotted openings c, through which the shafts c"- are adapted to extend. The butters e, which lie above the inner guide 0 of each pair, are connected together by a bar 0 so as to form substantially one butter, which extends from one throat to the other immediately over the apron b Extending under the forward portion of the platform is a transverse shaft 0, which carries a series of arms 6, one for each butter 0 0'. These arms are each provided in their upper ends with slotted openings 6, which engage over projections c on said but-- tors. A foot-lever c pivoted at one side of the frame in convenient reach of the operator, is connected by a link connection 0 to a small arm or lug c" on said shaft, so that a downward movement of said foot-lever produces a simultaneous inward movement of all of the butters, thus furnishing means by which the butts may be crowded baekwardl y against the abutment as the cornstalks are gathered onto the platform and apron by the packers.

As in my prior patent, the incoming stalks from the respective threats are separated by a divider f, arranged centrally between the same; but in the present case this divider f is hinged, as shown at f, to an upwardly-extending portion of the frame a, which also extends outwardly and forwardly to form bearings for the shafts c and c of the re speetive reels.

The shock-forming device is substantially the same as in my former patent. A pivoted frame 1 turns on suitable supports r rising upwardly at an angle from the frame (.1 (L. These supports also carry a track on which the frame 9 is furthersupported through the medium of rollers 51, by means of which the frame g is permitted to turn around the master-wheel and deliver the shock. An auxil iary frame g, which is adapted to slide through pivoted bearings g, carries the shockforming arms g, substantially as set forth in my prior patent.

In addition to the shock-forming arms I provide means for distending or spreading the bottom of the shock, so as to form the same open to permit the circulation of air to assist in drying the same. It is constructed as follows: Pivoted on a rod which forms a part of the auxiliary frame 1", is a projecting frame 5 which is slotted longitudinally and horizontally. At the forward end of this frame there are pivoted two arms g 9 which are pivoted at their extremities to two other arms g g, these arms 9 being in turn pivoted to a cross-bar g, which lies within the slotted opening of the frame. From the cross-bar there is extended baekwardly a link or handle g, which is adapted to rest in notches g formed in a finger g", which projects baekwardly from said frame.

011 the side of the machine opposite the shocker there is supported above the apron and also above the top of the abutment b a rod /L, and on this red there is sl idingl y men n ted a bar 7L, having a brace m, which projects outwardly and forwardly .from said bar and is also journaled on said rod. This bar 71. is also adjustable on the rod and is adapted as the platform is moved baekwardly to retain the tops and assist in shaping the stalks on the platform, so that they may be more readily gathered into a shock, the bar or curved brace being adapted to hold back the tops while the butts or stalks of the corn are moved baekwardly with the platform or apron.

In the present case the abutment I1 is made IIO ' in two parts, one part being connected rigidly with the platform and the other part 11 being formed in the nature of a gate and preferably having a central backwardly-projecting-bar N, which is supported above and below by suitable rollers b b on the stationary portion, so that the movable portion of the abutment may be moved laterally as desired.

In the operation of the machine the platform is advanced to the front by turning the apron through the medium of theshaft b and beveled gears b ,which engage the shaft b carry- 'ing the sprocket-wheels which operate the chains 17 b on said apron in the manner set forth in my previous patent, the vertical shaft 12 being adapted to receive a handle or crank for this purpose, as in my prior patent.

. around the same and winding itnp on the a in the slotted opening in, said frame.

windlass gn,substantially as. set forth in my priorpatent. This Windlass 9 7 I preferably construct at each end with continuous grooves whichfrun spirally around thewindlass from.

the ends inwardly, :so that the rope, as it is wound up, is also'carrie'd inwardly at a point behind the shock, causing the. portions of the rope on either side of the shock to approach each other, and thus assist in getting the shock in proper shape. Before theshocking-frame is raised to a vertical position the spreaderframeis raised to a position at right angles to the shocking-frame and the handle gl rwithdrawn,so as to close the arms 9 g 9 g ,with- The spreader is held in this position while the shocking-frame is being raised to a vertical position, so that the spreader partially enters the corn about to be formed into a shock. The.

corn form in g the shock is then drawn onto the shockin g-frame so that the spreader-frame g enters into the shock,after which the handle ispushed inwardly, thus opening the arms 9 g g and spreading the stalks, so as to form an opening in the center of the shock. After the shock is formed it is elevated on the main frame and swung around the frame-supports until clearof theframe in the manner set forth in the former-patent, the gate por-' tion of the abutment being pushed back out of the way to permit the shock to be swung around.

I have heretofore referred to the fact that I the arms 9 andthe spreader are supported on the auxiliary sliding frame g of the shocker. They are not, however, directly connected to said frame,but areconnected thereto through the medium of intermediate bars 9 which are connected to the auxiliaryframe slightly in front of t e same by clips 9, the intermediate bars 9 being adaptedto ,extend downwardly parallel with the auxiliary frame:

manner.

and support the arms g and spreader, sothat the auxiliary'frame may'slide through the bearings g to-a point which willcarry the lower arms 9? below said bearings, This construction permits the formation of ashock with short stalks and at the same time allows the shock to be lowered to the ground by the proper movement of the auxiliary frame.

- It should also be stated that the bar 72. is

adapted to be turned on the rod h, so as to raise it out of the way during the formation and discharge of the shock. It is normally held in its horizontal .position by a chain h .which .is connected to, an, extending lug h on said bar and to a rod b secured to a vertical portion of the frame. This chain 71. servesv tohold the rod in either position-that is to say, either in the normal horizontal position or when turned upwardly and backwardly to permit the discharge of the shock. The bar It is held in different positions on the rod h bya movable collar hf, having a set-screw 71 by meansof which it may be secured to said rod in difierent positions, and thus permit the bar to be held in the proper position to.

which extends through the yoke 70, having an upwardly-extending stem 10 to which the guiding-handle It is connected in the usual Of the three sections the middle section is is'plain on its periphery. The side sections k and 10 each has on the side' far- .thest removed from the middle section a peripheral flange, the three sections forming in effect a supporting and guiding wheel with a concave or channel-shaped periphery. The stem 10 extends upwardly through a suitable head or sleeve 10 in the tongue, and immedi-- ately above this sleeve, preferably forming a part thereof, is a foot-rest it for the driver.

each journaled loosely on the same axle k The construction of. the guiding-wheel is such that the position of said wheel maybe moved moreeasily than ifthe wheel was cast integral with the flanges.

At the same time theflanges prevent slipping of the wheel and secure more certainty in the. guiding action.

The'wheel'may. be turned to anyposition:

while the machine is stationary, if so desired,

as the different sections are free to move in tionin. the other direction.
