is a sectional view taken substantially on the 1118 5-5 of Fig. 4; Fig. 6 is a sectional a citizen of the United States, residing at view taken substantially on the line 66 Brandon, in the county of Fond du Lac and State of lVisconsin, have invented certain new and useful Improvements in Harvesters, of which the following is a SPBClfiCfltion, reference being had to the accompa- This invention relates to certain improve ments in harvesters and has relation morparticularly to a device of this general char acter especially designed and adapted for ings, 1 denotes use for harvesting hemp and an object of the invention is to provide a device of this general character having novel and improved means whereby the stalks, afterbemg severed, are supported and conveyed in a standing position for a predetermined distance and spread upon the ground with the buttends of the stalks pointing toward the" standing grain. 7 V It is also an object of the invention to provide a novel and improved device of this general character comprising gathering means projecting forwardly of thecutting mechanism and operating to bunch the upper portions of the standing grain before the same is severed by the cutting mechanism. 7 The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved harvester whereby certain important advantages are attained and'the device is rendered simpler, less expensiveand otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a side elevational view of a harvester constructed in accordance with an embodiment of my invention; Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1; Fig.8 is a fragmentary front elevational view, illustrating the means, herein embodied, for imparting reciprocating movement to the sickle. Fig. 4 is afragmentary rear elevational view, illustrating the means, herein embodied, for operating the belt and spreader chains included in the present embodiment-of my invention; Fig. 5

pin 14 projecting from the disk of Fig. 1, with certain of the parts omitted in order to clarify the disclosure; Fig. 7 is rfragmentary view in top plan of my device as herein disclosed, with parts omitted for purposes of distinctness; Fig.

a sectional view taken substantially on the Fig. 2; V arged fragmentary detail view, illustrating he means for operating the driving chain. As disclosedin the accompanying drawa frame of predetermined dimensions and configuration having operatively engaged therewith, the supporting wheels 2 and'3, the wheel 2 being herein set forth as the driving wheel and having the shaft 4 thereof operatively engaged, as indicated at 5, with the driving shaft 6 suitably supported by the frame 1.

The major portion of cured thereto a platform 7 provided along its forward marginal portion with a conventional-cutting mechanism including a guard 8 and the reciprocating sickle 9, said sickle being herein'disclosed as having operatively engaged therewith an extremity of a pit man 10, the opposite extremity of which is pivotally engaged with the swinging arm 11 depending from the frame 1. Also pivotally engaged with the arm 11 is the pitman 12 which is operatively engaged with a wrist disclosed as fixed to the forward extremity of the transverse shaft 16. 'The shaft 16 is operatively connected, as at 17 with the shaft 18 disposed longitudinally of the frame 1 and below the platform 7, fora purpose to be hereinafter more particularly referred to, and said I connected, as at 19, with the shaft 6 where by it will be readily perceived that the sickle 9 will. be caused to reciprocate upon rotation of the wheel 5.

Pivotally engaged at theirlower extremi-J ties with the frame 1 are the transverse alined series of supporting rods'20,'21 and 22 maintained in-adjusted position relative to the platform 7 by thelever 23 carried by the shaft 24 disposed longitudinally of the device below the platform 7, and such lever 23 is provided with aconventional 1atchcoacting with the rack 25.1 As herein embodied, the series of rods 20 .tively, are three in number and the rear rods 15, herein shaft 18 is operatively and 22, respec-.

the'frame 1 has se- 7 that this adjustment is supporting rod 20 is operatively connected.

through the medium of the link with the slide member 31 operatively engaged with the rear-wardly disposed guide 32 carried by the frame 1, and said guide is in turn operatively engaged through the medium of the links 33 with the upstanding rock arm 34 carried by the shaft 24, while such rock arm 34 is operatively engaged with the intermediate rod 20 and forward rod 20 through the medium of the links 35 and 36, respectively. By this arrangement, it will be seen that upon proper manipulation of the lever 23, the rods 20 and 22 will be moved in unison and in the same general direction, and it will be further observed. for the purpose of maintaining the mechanism, hereinafter to be described, in a predetermined relation to the surface over which the machine is traveling. As the rods 21 are adapted to be operated in a manner similar-to that set forth relative to the rods 20, it is not believed that an additional detailed description and illustration is necessary.

Supported by the forward rods 20, 21

and 22 are the plates 37 having the forward portion of their opposed edges disposed in diverging planes and such plates terminate slightly in advance of the cutting mechanism, as is believed to be clearly shown in Fig. 2, and are adapted to serve as-guides for the butt ends of the stalks as the same are caused to move inwardly under the influence of the platform chains 38, herein disclosed as directed around the sprockets 39 and 40. The sprockets 40 are operatively connected with the vertically disposed flexible shafts 41 which depend below the platform 7 and have fixed to such lower extremities, the sprockets 42 operatively engaged by the drive chain 43 whereby said shafts are caused to rotate in the requisite relative directions. The drive chain 43 is disposed around the sprocket 44 operatively supported by the frame 1 and provided with a face gear 45 in mesh with a gear 46 carried by.

the shaft 18 whereby it will be readily perceived that the shafts 41 will be caused to rotateupon the travel of the machine.

At a predetermined distance above the plates 37 are adjustablyconnected with the forward rods 20, 21 and 22, the plates 47 projecting a predetermined distance in adflexible shafts 41 and vance ofthe cutting mechanism and having the opposed edges of the projected portionsarranged in diverging planes, as is believed to be particularly shown in Fig. 6, and said plates have mounted thereon the guide sprockets 48 around which are directed the gathering chains 49 which are also disposed around the sprockets 50 fixed to the 50 said gathering chains 49 are driven. By this arrangement, it will be perceived that the gathering chains 49 will bunch the tops of the stalks-before the stalks are engaged by" the cutting mechanism. At r'edetermined distances above the plates 47 are the plates 51 on which are operatively supported the sprockets 52 around which around the sprockets 54 fixed to the hemble shafts 41 and whereby said chains 53 are driven. The chains 53 are disposed transversely above the platform 7 a distance substantially equal with that of the gathering chains 38 and serve to maintain the severed stalks in a. vertical position espe-' cially during the period that the butt ends of the severed stalks are the gathering chains 38.

from which sprockets so are V disposed the conveyer chains 53 also directed ll: as

being bunched by "As is believed to be self-evident,the chains 5 38', 49 and 53 carry the severed stalks'rearwardly of the device and transversely of theplatform 7 and deposit the same in a. vertical position upon the endless conveyer 55, the upper stretch of which travels in a I 1 direction away is disposed supported by manner, and

The upper sprocket 67 is mounted upon a shaft 69 operatively engaged, as at 70, with a shaft 62. It is thought to be obvious that the spreader chain 67 will serve to spread the stalks upon the ground with their butt ends pointing toward the standing grain. It is also to be observed that the plates 47 and 51 are adjustably connected, as indicated at 71, with the respective rods 20, 21 and 22 in order to compensate for the varying heights of the standing grain.

From the foregoing description, it is thought to be obvious that a harvester con-. structed 1n accordance with my inventlon 1s of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it maybe assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principlesand spirit thereof and for this reason I do notwish to be understood as limiting myself to the precise 'ar 'rangement and formation of the several parts herein shown in carrying out my invention in practice.
