, invention relates to harvesting ma chinery of the class oft-harvesters and binders and more particularly to the eleyator structure, bywhich cut grain is conveyed to the binding mechanism, and to means' employed for supporting and adjusting the upper elevator to preserve its proper and most eifective operative position relative to the lower elevator with which it cooperates in 1Q conveying cut grain and delivering it to the binder deck. 7 r 1 2 Referring to the drawings in which similar numerals indicateidentical parts:

In the developmentof the harvester and binder in which an elevating structure was first employed to receive and convey cut grain from a platform conveyor and deliver it to the binding mechanism, the structure comprised an upper and a lower canvas conveyor operating overrolls rigidly supported in the front and rear parts of the elevator frame. In this construction, the front and rear of the space between the conveyors was closed and consequently the length of grain which could be harvested and bound was limited. To overcome this objectionable feature and accommodate a harvester and binder to any length of grain, a frame was cleveloped'in which the frontof the upper and lower elevators was supported, asat present, but the rear of the lower elevator was supported rigidly on the harvester frame, and the rear of the upper elevator was supported on an arched seat support. tion provided an open rear to the space between the upper and lower elevators and made it possible to harvest grain of any length and successfully elevate it to the bind- 59: er, the upper elevator being attached to and This construc supported on the seat support only. Because of the rough and arduousworkof; harvesting, it became apparent that the upper elevator, supported at only one point rearwardl'y, was liable to sag at itsrear upper end anddestroy the proper relation of the two elevators for eflicient operation, a defect which demanded a remedy operable to overcomeany sag thatmight occur, a demand that has been met by various devices possessing features of adjustment by which the proper position of the elevator can be maintained; and to this class of devices my invention belongs, and hasfor its object to "provide a simple and economical device by the, adjustment of which the upper elevator can be kept in proper operative position relative to the lower elevator, a device which is easily and readily adjustable by one person and very efliective for the purpose for which it. was, designed.

As stated suflicient of a. harvester andbind eris shown to illustrate the application and operation of my inventiomand it includes parts 1 of the harvester frame-supporting the. rear lower elevator frame 2; An arched seat beam 3, of'a common type, is secured on the harvester frame and imou-nted thereon is a seat support 4 having a spring 51interposed between the beam and support, both the support and-springbeingrsecuredto the beam 3 bybolts 6 and 7. Rigidly secured, stubble ward, on the rear. of thefr'ame 8 of the upper. elevator 9, is abracket lOhaving a. rearwardly extendingpart llprovided with an eye for reception of afrod or-bar 12,'whichis adapted to be moved-lengthwise in said eye-t by. operation of a nut 13 on theendofthe rod and on the stubbleward side of the partll, the end oftherodbeingthreadeoha jam nut 14, on the opposite side ofthe part-11, and on the rod '12, is=utilized :to hold the rod from. longitudinal movement; 2 Thetoppositeend j of the rod- 12 is secured to: the seat'beam 3.

Arvertic'ally' disposed 11111;.15 is rigidly se- 9 cured. onthe beam 3 by abolt 16 extending horizontally through thefbeam 3 Sand transversely thereof; the 1'5.*extendsfdown-' wardly and is bent-to preventa. flat surface to thereae ofi'theuppenelevator fmmei .011 P the lower end of the link 15, and preferably integral therewith, is a part 17 provided with a slot 18, alined with the inclination of the frame 8, through which extends a bolt 19 on the frame 8 by which the link 15 is secured to the frame 8 and held in place by a nut, a serrated washer being interposed between the nut and the face of the part 17, which is also serrated, as shown. Opposite the link 15 and rigidly secured on the beam 3 by the bolt 6 is a link 20 extending downwardly transversely of the link 15 to which it is attached by a rivet 21. The lower end of the link 20 forms an eye 22 through which extendsa rod 23 on the end of which, and on the stubbleward side of the eye 22, is a nut 24. The lower end of the rod 23 is provided with an eye by which said rod is secured to the crank end of the rod of the canvas tightener.

The parts as shown and described are in perfect operative position. Now,'presuming that the upper elevator 9 has sagged at its upper end and I desire to remedy the defect, I loosen the jam nut 14, and the nut 19. If the rear upper end of the elevator 9 is too close to the lower elevator, I shorten the connection with the rod 12 by turning the nut 13 in the right direction until the required adjustment has been made after which the jam nut 14 is operated to hold the parts in the new position and the nut 19 is tightened. If the elevator 9 has a longitudinal sag, it is readily corrected by loosening the nut on the bolt 19 and the 1' am nut 14; the adjustment is effected by operation of the nut 24, the bolt 19 moving freely in the slot 18. Upon the proper position of the elevator 9 being attained, the nuts loosened are again tightened. During the adjustments, for either of I the purposes stated, the elevate-r 9 is firmly supported on the seat beam 3; consequently, either or both adjustments can be readily and quickly efiected by one operator.

What I claim is:

1. In a harvester binder, the combination with upper andlower elevator frames and a support, of a bar attached to the support ex tending stubbleward and adjustablyconnected to the upper elevator frame, a support for said frame attached to the support extending downwardly therefrom and connected to said frame, and means operative to adjust said frame longitudinally on said support.

2. In a harvester binder, the combination with upper and lower elevator frames and a support, of a bar attached to the support extending stubbleward and adj ustably connected to the upper elevator frame, a support for said frame attached to the support extending downwardly therefrom and connected to said frame, and means connected with said frame and to said support and operative to adjust said frame longitudinally.

3. In a harvester binder, the combination with upper andlower elevator" frames and a support, of a bar attached to the support extending stubbleward and adjustably connected to the upper elevator frame, a support for said frame comprising links attached to said support and extending downwardly, one of said links adjustably connected to said frame, and a bar extending longitudinally of said frame and attached thereto and adjustably connected to the lower end ofthe second link.

4. In a harvester hinder, the combination with upper and lower elevator frames and a support, of a bar attached tothe support extending stubbleward and adjustably connected to the upper elevator frame, a support for said frame comprising links attached respectively to opposite sides of said support and extending downwardly, one of said links adjustably connected to said frame, the second link extending downwardly in a stubbleward direction and rigidly secured to the first link, and a bar connected with said frame and adjustably connected to the lower end of the second link.

5. In a harvester binder, the combination with upper and lower elevator frames and a support, of a bracket on the upper frame, a bar attached to the support extending stubbleward and adjustably connected to said bracket, a support for said upper frame comprising links attached respectively to opposite sides of the support and extending downwardly, one of said links perpendicularly disposed and having its lower end adjustably attached to said frame, the second link extending diagonally downwardly over the first link and rigidly secured thereto, and a bar extending longitudinally of said frame and attached thereto and adjustab ly connected to the lower end of the second link.
