(01. 56-23? ' , ‘The present invention relates to harvesting ' machinery and more particularly to windrowers, and an object of the invention ‘.is to generally improve the construction and operation of ma \ ' 2 1 also. to. shield. wheel W1 from material. being . posited'through opening D. Atubular element 18 (see also Fig. 1-) is connected with member I5 of frame'portion H preferably by a clip-‘likeele chines of this class. More‘speci?cally, an object I ment |9and extends inwardly and upwardly to a of 'theinvention is'to improve‘thejframe-work ' ' point‘of connection 28 with above-mentioned wall and general construction of such machines.

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. of the machine and the croprbeing out. It is also very strong in, torsion and resists warping’ or twisting of platformPdueto the backward re action of the cutter'bar which is unavoidably Fig. 3. is, a detail. of certain mechanism in dicated in Fig. 1. major downward. loads resulting from the weight 7 As seen in Fig. 1,- the machine comprises a frame. generally designated as _F carried by ground wheels W1 and W2, frame F carrying a cutter bar generally designated as C and a plat form generally designated as P. Platform P is spaced from wheel W1 to. provide a delivery open ing D. Frame F also carries a reel R. and in fact applied to frame. portion LI. and end structure 2| at a point. spaced below member [8, thus result ing in. a twisting force‘ in member l8. Atdraw bar 23 is pivoted at 24 and‘25 to the forward partv of- frame. portion’ H and is adjustable in its angular relation therewith by a" lever 26v pivoted at 21. to drawbar 23 and/[cooperating with a quadrant member 28 ?xedzwith draw bar 23. A link 23 pivoted tovlevuer. 26 at 30' extends back to, a pivotal connection 3i Witha» portion. of- up standing wall H. A detent member :32 on lever 26¢ maintains leverzein adjusted relation with quadrantza in well~known manner and accord ingly maintains the‘ adjustment of draw bar 23, substantially all of the various parts commonly 40 or rather frame portion *l-t relatively to draw associated with amachine of this character. ‘ Inthe present instance, wheel W1 is journaled The several parts: of, the machine are actuated on an axle l0, Fig. 2, carried in a frame portion from wheel W1‘. In the. present instance» a generally designated as H and comprising longi-v sprocket 33r?xed with the wheel drives, through bar 23-. V > ' u I v tudinal members I2 and 13 and front and rear 45 a chain“, a sprocket 35 Fig. 5-on a shaft 36. crossmembers It and l-5,.Fig. 1, members I3 and Shaft 36 drives a bevel gear 31- which drives a l4. being united by a portion I 6, Fig. 2. The bevel gear 38; on a shaft 39‘, the several shafts various. portions form a roughly rectangular and gearsbeing carried in a casing 4a. Shaft 39 frame surrounding and enclosing wheel W1 and’ as more particularly seen in Fig. 2, carries a» generally disposed in a horizontal plane. Cutter 50 crank» 41* engaged by a pitman 42v connected to a. bar C originates at frame portion H and extends sickle 4'3 which'is reciprocated in the usual man laterally of the machine at the lower front por ner by rotation of shaft 39. tion thereof. Between wheel W1 and platform Platform P has an apron or draper 44, Fig. 1, P is an upstanding wall I‘! connected with ‘mem traveling about rollers 45 and 46 for feeding the ber l3 and serving as a part of the structure and 65 cut crop toward delivery opening D. Roller 45 - 2,410,904 3 4 is ?xed with a shaft 41 on which is mounted, in projects somewhat beyond the end of windshield 13 into opening D. In operation the machine is drawn by a tractor ‘ 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 ?tting 5| provides a or other means attached to draw bar 23, the rota tion of wheel W1 actuating the several machine units as described, whereupon material is cut by cutter bar 0, laid on conveyor 44 by reel R and conveyed by conveyor 44 into opening D, thus forming a continuous windrow behind the ma bearing 52 for shaft 53 on which is ?xed a pulley 10 chine. The problem of conveying motion to con 54. Fitting 5| also provides a fulcrum 55 Fig. 3, ' _ - veyor 44 without encroaching upon opening D is for a lever 56 with which is ?xed a stud or jour nal 51. A sheave or idler pulley 58 is rotatably carried on journal 51 and a tension member 59 solved by carrying belt 6!] completely clear of opening D, frame I8 and windshield 13, on stand ard 50, the motion of belt 60 also serving to drive adjustably connects lever 56 with standard 50.7 Adjustment of member 59 will accordingly raise [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 A belt 60 extends about above mentioned pul Letters Patent of the United States is: ley 49, upwardly and over pulley 54, downwardly and‘about pulley 48, upwardly and over pulley 20 ,LUA windrower having a frame generally transverse to the direction of movement thereof, 58, and again downwardly to above mentioned a drive wheel at one end of the frame, a platform pulley, 49. In this‘manner belt 60 is carried supported from the frame and spaced-from the acrossopening D and will not interfere with the drive'wheel to provide an opening for depositing depositing of material behind the machine. Ro tation of shaft 39, however, will drive shaft ,4‘! 25 a windrow, a conveyor on the platform for feed ing out crop to the opening, said frame includ andalso pulleys 54 and 58 by virtue of move ing a portion extending about the drive wheel in ment ‘of belt 60 caused by rotation of pulley '49. a’ substantially horizontal plane, a sickle extend As seen more particularly in Fig. 2, reel R is ing from said portion across the machine at the built‘about a shaft 6| carried in a bearing 62 frontthereof, said frame comprising a tubular supported on a standard 63 carried in any suit- . member extending across the machine at a level able or well-known mannerv in the present in above said sickle, an upstanding wall between stance from wall 11. Standard 63 is slidable on said wheel and said opening, and said tubular a' staff 63“ supported from wall I‘! by a bolt or or lower pulley 58. the like 53” and is welded or otherwise suitably secured'to, bearing 62 in well-known manner, a piniliilc engaging‘one or another of holes 6311 in staff 638L 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 member being united with said wall'and bending down behind said Wheeland being united with said‘. aforementioned portion, a draw bar pivoted to saidaforementioned portion and, means for adjusting the angular relation between said frame portion and said draw bar.

Accordingly motion the drive- wheel to provide an opening for depos of belt 60 in rotating pulley 54 will cause rota iting a windrow, aconveyor on the platform for tion of reel R. feeding cut crop to the 0pening,,a shaft on the Reel shaft BI is supported at its other end by frame adjacent to the drivewheel and driven a bearing 68 on an arm 69 fulcrumed at 10 to a thereby, said frame including a portion extend curved arm or standard ‘H extending upwardly supported from bearing, 62. andl‘forwardly from above mentioned structure 2|; A tension member 12 also connected with I 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 has‘a shaft 15 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 elima inated.
