KAFIR-CORN HEADER.

Application filed November 15,-1915.

To all whom it may concern:

Be it known that I, JAMES F. FERGUSON, a citizen of the United States, residing at Comanche, in the county of Stephens and State of Oklahoma, have invented certain new and useful Improvements in Kafir-Corn Headers, of which the following is a specification, reference being had to the accompanying drawings.

This invention pertains to improvements in machines for heading corn, Kafir-corn, cane, and other grains or cereals which develop into a head, and more especially to the class of machines in which a sickle is employed to sever the heads of grain and in which an apron is employed to carry the severed heads from the sickle to the apron.

An object of the invention is to provide improved means for gathering the stalks of grain into position to be severed by the sickle.

Other objects and advantages of the in vention will be set forth in the ensuing description.

The accompanying drawings show one embodiment of the invention in practical form.

Figure 1 is a left-hand side elevation of the improved machine. Fig. 2 isa plan view of the machine. Fig. 3 is a plan view of a portion of the machine on larger scale, the lower side. of the figure being the front. Fig. 4 is a plan view of a reciprocating sickle. Fig. 5 is an elevation view of the parts shown in Fig. 3.

Referring to the several figures, in all of which like characters of reference designate like parts, a Wagon or other suitable vehicle having a box is employed as a part of the machine, and adapted to support the other parts.

In attaching the improved parts to the box 10. a wooden bar 11 is mounted crosswise of the rear end of said box and extended out laterally from one side thereof, this bar being clamped down on the box by bolts 12 whose lower ends are anchored in a bar 13 extending across under said box. The projecting end of this bar 11 is reinforced by a bar 14 of like dimensions, which is bolted to its front face, thus providing a wide upper face 15 to which other parts may be bolted.

A shaft 1.6 is journaled in the front ends of forwardly-projecting bearing arms 17 which are bolted to the upper face 15 of Specification of Letters Patent.

the bars 11 and 14 outside the box 10, the inner end of this shaft projecting in over the box and being supported by a bearing arm 18 bolted to the bar 11. This shaft 16, while serving as a pin on which other parts are pivoted, is adapted to be revolved to drive certain parts of the machine and is provided with a tight sprocket-wheel 19 which receives motion through a link belt 20 from a larger sprocket-wheel 21 on a In further arrangement, a frame 23, is pivoted on the shaft 16 outside the box 10, the front end of this frame carrying means for cutting off the heads of grain and also carrying the front or lower end of an endless apron 24 which carries the severed heads rearward from the cutting means. To support the front end of the frame 23, a standard25 is erected on the side 26 of the box 10 adjacent said frame, and on this standard a lever 27 is fulcrumed.

A yoke 28 is suspended from the end of the lever 27 by strap-iron bars 29, and the sides of the frame 23 are suspended from said yoke by rods 30; the opposite end of the lever being held down by engagement with a standard 31 on the opposite side 32 of the box 10.

The front or lower end of the endless apron 24 is carried by a roller 33 whose shaft 34 is j ournaled through the front portion of the frame 23, while the rear or upper end of said apron is supported by a similar roller 35 whose shaft 36 is journaled through an upward and rearward extension 37 of said frame; and this apron is driven by means later described.

In arranging the cutting means, the front end of the frame 23 is itself formed as an integral cast frame 38, best shown in Fig. 5, which is bolted to the side pieces 39 of said frame 23. This cast frame 38 is provided at its upper edge with forwardly-projecting sickle guards 40, not unlike those of other harvesting machines, and with a sickle 41 adapted to reciprocate through said guards.

To drive the sickle 41, a shaft 42 is journaled horizontally through the lower part of the cast frame 38 and a short shaft 43 is journaled vertically through the inner end of said frame, these two shafts being operatively connected by two gear-wheels 44 and 45; and the upper end of this shaft 43 is provided with a crank-wheel 46 which imparts motion to the sickle through a connecting-rod 17. The outer end of the shaft 12 has a tight sprocket-wheel 48 which receives motion through a link belt 49 from a larger sprocket-wheel 50 on the outer end of the shaft 16; and by the arrangement of parts shown it will be seen that forward movement of the wagon drives the sickle 11.

To drive the apron 24, the shaft 34 of its lower front roller 33 is provided with a sprocket-wheel 51 which is operatively engaged and driven by the link belt 49.

In providing improved means for gathering the stalks of grain to the sickle 41, a reel 52 is carried by the upper end of a short shaft 53 which is journaled vertically in the outer portion of the cast frame 38, this shaft and the horizontal shaft 12 being operatively connected by beveled gear-wheels 5 1 and 55. This reel includes radial arms 56 which are riveted to its hub 57, and outer arms 58 which are riveted to said arms 56 and disposed on a forward tangent. lVith this reel 52 arranged in this way, and re volving in the direction of the arrow B of Fig. 3, it has a hooking engagement with the stalks of grain, gathering said stalks more effectually than can be done by radial arms alone. A second and smaller reel 59 is arranged at the inner end of the cast frame 38 and pivoted revolubly on the upper end of a rigid spindle 60 whose lower end is bolted to the front face of said frame. Like the larger reel 52, this reel 59 comprises radial arms 61 which are riveted to a central hub 62, and outer arms 63 which are riveted to said arms 61 and tangentially arranged; but these arms 63 are disposed on a back tangent in place of on the forward tangent of the corresponding arms 58 of the reel 52. The back tangent arrangement of the arms 63 of the smaller reel 59 obviates all conflict between the two reels in releasing engagement of the severed heads of grain and allows said heads to be thrown onto the apron 24: by the larger reel 52.

' To drive the smaller reel 59, it is provided with pins 64: which project upward from its tangent arms 63, and these pins are engaged by the tangent arms 58 of the larger reel 52.

In bringing the arms 58 of the larger reel 52 into driving engagement with the pins 6 1 of the smaller reel 59 or with any other projecting part of said reel for the purpose of driving it, there is a tendency to catch and clamp stalks of grain between the two reels or projecting parts of them, and this clamping engagement of the stalks tends to hold them more positively in position to enter between the sickle guards 10.

Having thus described the invention, I claim 1. In a corn header, means for severing the stalks of grain, a reel arranged at one side of said means and having projecting arms, a reel arranged at the opposite side of the severing means and having arms adapted to be engaged by the arms of the first-named reel, and means for driving the first-named reel.

2. In a corn header, means for severing heads of grain, a reel arranged at one side of the severing means and arranged to revolve in a horizontal plane, said reel having projecting arms, a second reel arranged at the'opposite side of the severing means and adapted to revolve in a horizontal plane, said second reel having projecting arms and pins.

projecting upward from said arms, the arms of the first-named reel being adapted to engage said pins to drive the second reel, and means for driving the first-named reel.

3. In a corn header, means for severing the heads of grain, a reel arranged at one side of the severing means and adapted to revolve in a horizontal plane, said reel comprising radial arms and an outer series of arms secured to said radial arms on a forward tangent, a second reel arranged at the opposite side of the severing means and adapted to be revolved in a horizontal plane, the second reel comprising radial arms and an outer series of arms secured to its radial arms on a back tangent, the second reel having a series of upwardly-projecting pins adapted to be engaged by the arms of the first-named reel to drive said second reel, and means for driving the first-named reel.

WVitness my hand this 9th day of October,

J AMES F. FERGUSON.
