2 Claims.

Th present invention relates to harvesting 2 1 also. to. shield wheel W from posited'through opening D. Atubular element 18 (see also Fig. 1-) is connected with member I of frame'portion H preferably by a cliplikeele- I ment |9and extends inwardly and upwardly to a pointof connection 28 with above-mentioned wall further object is to provide a novel drive for the a reel and incidentally, to provide for actuating the conveyor which is located across thedischarge opening from the other parts of the machinery.

' Further objects and advantages will become apparent from the following specification and accompan-yingdrawings in which a satisfactory embodiment. of the invention is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention as herein expressed.

Figure 1 of the drawings is a rear elevation of a windrower or windrow harvester embodying the invention. i

Fig. 2 is a perspective View of a portionof the same. taken from in front and to the left, with parts removed and others broken away. I

Fig. 3. is, a detail. of certain mechanism indicated in Fig. 1.

Fig... 4 is av plan view with parts broken away of certain mechanism indicated in Fig. 2, and

Fig. 5 is an enlarged plan' View, diagrammatic in character of certain mechanism indicated in Fig. 1. 7

As seen in Fig. 1,- the machine comprises a frame. generally designated as F carried by ground wheels W and W frame F carrying a cutter bar generally designated as C and a platform generally designated as P. Platform P is spaced from wheel W to. provide a delivery opening D. Frame F also carries a reel R. and in fact substantially all of the various parts commonly associated with amachine of this character.

Inthe present instance, wheel W is journaled on an axle l0, Fig. 2, carried in a frame portion generally designated as H and comprising longitudinal members I2 and 13 and front and rear crossmembers It and l-5,.Fig. 1, members I3 and l4. being united by a portion I 6, Fig. 2. The various. portions form a roughly rectangular frame surrounding and enclosing wheel W and generally disposed in a horizontal plane. Cutter bar C originates at frame portion H and extends laterally of the machine at the lower front portion thereof. Between wheel W and platform P is an upstanding wall I! connected with member l3 and serving as a part of the structure and I1. Member lS-then extends across the machine substantially parallel to. cutter bar 0 and unites with end structure 2 I carried in any suitable or well-known'manrier on wheel W Platform P iscarri'ed. onstructure 2!,v by cutter bar C, and also. bye strut z-zidependmg from. tubular element t8- Platforml? is spaced appreciably from wall ll so astoleave above mentioned opening D for. the deposit of the harvested material in the: form of a windrow as themachine moves along. 7 V

-With.the structure thus far described, it will be seen that, tubular member-f8 forms the major,

structural unit in the machine and carries the major downward. loads resulting from the weight of the machine and the crop being out. It is also very strong in, torsion and resists warping or twisting of platformPdueto the backward reaction of the cutter'bar which is unavoidably applied to frame. portion LI. and end structure 2| at a point. spaced below member [8, thus resulting in. a twisting force in member l8. A draw bar 23 is pivoted at 24 and25 to the forward partv offrame. portion H and is adjustable in its angular relation therewith by a" lever 26 pivoted at 21 to drawbar 23 and cooperating with a quadrant member 28 fixed with draw bar 23. A

link 23 pivoted tovlev er 26 at 30' extends back to a pivotal connection 3i Witha portion ofupstanding wall H. A detent member :32 on lever 26 maintains leverzein adjusted relation with quadrantza in well-known manner and accordingly maintains the adjustment of draw bar 23, or rather frame portion *l-t relatively to draw bar 23-. V u I v The several parts: of, the machine are actuated from wheel W In the. present instance a sprocket 33 fixed with the wheel drives, through a chain, a sprocket 35 Fig. 5-on a shaft 36. Shaft 36 drives a bevel gear 31- which drives a bevel gear 38 on a shaft 39, the several shaftsand gearsbeing carried in a casing 4a. Shaft 39 as more particularly seen in Fig. 2, carries a crank 41* engaged by a pitman 42 connected to a sickle 4'3 which'is reciprocated in the usual manner by rotation of shaft 39.

Platform P has an apron or draper 44, Fig. 1, traveling about rollers 45 and 46 for feeding the cut crop toward delivery opening D. Roller 45 material being is fixed with a shaft 41 on which is mounted, in the present instance, a pulley 48. On above mentioned shaft 39 is a pulley 49 from which motion is transmitted from shaft 39 to shaft 41 as will appear.

Upstanding wall I! carries a standard 50 which extends upwardly and to the right as seen in Fig. 1, to a point partially over above mentioned opening D. At this point a fitting provides a bearing 52 for shaft 53 on which is fixed a pulley 54. Fitting 5| also provides a fulcrum 55 Fig. 3, for a lever 56 with which is fixed a stud or journal 51. A sheave or idler pulley 58 is rotatably carried on journal 51 and a tension member 59 adjustably connects lever 56 with standard 50.

Adjustment of member 59 will accordingly raise or lower pulley 58.

A belt 60 extends about above mentioned pulley 49, upwardly and over pulley 54, downwardly and about pulley 48, upwardly and over pulley 58, and again downwardly to above mentioned pulley, 49. In this manner belt 60 is carried acrossopenin D and will not interfere with the depositing of material behind the machine. Rotation of shaft 39, however, will drive shaft ,4! andalso pulleys 54 and 58 by virtue of movement of belt 60 caused by rotation of pulley 49.

As seen more particularly in Fig. 2, reel R is builtabout a shaft 6| carried in a bearing 62 supported on a standard 63 carried in any suitable or well-known manner in the present instance from wall 11. Standard 63 is slidable on a' staff 63 supported from wall I! by a bolt or the like 53 and is welded or otherwise suitably secured'to, bearing 62 in well-known manner, a pin liil engagingone or another of holes 63 in staff 63 for determining the height of bearing 52., Shaft 6i has a bevel gear 64 meshing with a bevel gear 65 carried in a bearing portion 66 supported from bearin 62. connected by a tumbler shaft of well-known construction generally designated as 61 with above mentioned shaft 53, Fig. 1. Accordingly motion of belt 60 in rotating pulley 54 will cause rotation of reel R.

Reel shaft BI is supported at its other end by a bearing 68 on an arm 69 fulcrumed at to a curved arm or standard H extending upwardly and forwardly from above mentioned structure 2|; standard H is adjustable in length in well-known manner for changing the position of arm 69. Above mentioned bearing 62 is also adjustable in position in well-known manner forming no part of the present invention.

A windshield 13 is arranged behind platform P and attached to structure 2| and strut 22 to prevent blowing of material on conveyor 44, and extending substantially to the left extremity of conveyor 44 as shown in Fig. 1. A roller 14, in the present instance of angular cross section, is supported substantially parallel to roller 45 and hasa shaft carrying a pulley I6. Pulley I6 is driven by a short belt 11 from a pulley 18, in the present instance immediately behind above mentioned pulley 48 on shaft 41. Roller 14 catches material being discharged from conveyor 44 and assists in guiding it into opening D. In this manner any tendency for material to follow around beneath conveyor 44 is substantially elim inated. Roller 14, as clearly shown in Fig. 1,

Bevel gear 65 is A tension member 12 also connected with I veyor 44 without encroaching upon opening D is solved by carrying belt 6!] completely clear of opening D, frame I8 and windshield 13, on standard 50, the motion of belt also serving to drive reel R.

The above being a, complete description of an illustrative embodiment of the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is:
