COMBINATION HARVESTER 'THRASHER.
' Application filcdzFebruary 1c, 1924. Serial No. 693,441.
To all whom it may concern: I
Be it known that I, ERNEST GOBURN, a
citizen of the United States, residing at' Racine in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Combination Harvester Thrashers, of which the following'is a specification.
present invention relates to improvements in combination harvester-thrashers of the character disclosed in Letters Patent No. 1,498,354 issued June 17 1924, upon my application and particularly to the mechanism for connecting the leveling wheel to the thrasher whereby I provide a yielding and stable means for the purpose which positively control the variable movement of certain partsof the. machine, all as will be hereinafter more fully explained.
In the accompanying drawings, forming part hereof, Figure 1 is a rear elevation of a 'harvester-thrasher embodying my invention; Fig. 2 a plan of the improved flexible connection which I employ; Fig. 3 a transverse sectional view of the stub axle and parts associated therewith; Fig. 4 a fragmentary side elevation of the thrasher showing the rackbar and associated parts; Fig. 5 aplan of the thrasher and my improved flexible connection; and Fig. 6 is a detail rear elevation indicating in full and. dotted lines the range of adjustment of my improved flexible connection.-
In said drawings the portions marked 5 indicate the thrasher mounted upon an axle, 6, which supports a bull-wheel, 7, the harvester or header, 8, being supported from the axle, 9, which is provided with a grain wheel, 10, at its outer end, and at its inner end is flexibly connected to a stub axle, 11, for supporting a leveling wheel, 12, all of which elements are described in the patent herein referred to.
Upon said axle 11 I provide a sleeve, 14,.
I insert a rotatable connecting member, 20, having a neck, 21, near its inner end, about which I position a split collar, 22, through which and the axle 11 and sleeve 14 registering holes are provided in which screw bolts, 23, are inserted for securing said parts connecting member, 26, is rotatably mountedin axle 6, the arm, 27, of-which is considerably longer than the arm 28 of member v20, the ends of said arms being pivotally connected by a bolt, 29,, or otherwise. Said member 26 is mountedin a bushing, 30, se
cured thereto. by a set screw 30 and its inner end is provided with a neck, 31, and head, 32,'and is held in position by a split collar,
83, and screw bolts, 34, in a manner similar to member 20.
As is well known in practice, combination harvester-thrashers occupy considerable ground space. and in traveling are subjected to irregular movements in relation to each other because of the constantly changing ground irregularities, and it is highly important that the movements of the leveling wheel shall at all times harmonize with those of the thrasher, without liability of unduly straining the connections between them.
In the operation of such machine with my improvements embodied therein the scissorslike connecting members 20 and 26 being both pivotally mounted as shown are highly sensitive to the irregular movements of the wheels 7 and 12, and when there is the slightest variation in their relative movements the horizontal portions of the connecting members will rotate, carrying their arms 27, 28, in the same direction, but as one of said arms is shorter the range of movement thereof is such that whenleveling wheel 12 travels over ground higher or lower than that upon which wheel 7 is moving the absolute perpendicular position of rackbar 16 is maintained during its elevation and descent without any tendency of binding in its actuating mechanism, which has been a troublesome defect experienced in the operation of harvester-thrashers, and by so controlling the free movement of said rackbar at all times such objection is overcome. As indicated by the full and dotted lines in Fig. 6, the peculiar connection produced between arms 27, 28, constantly control the vertical movements of rackbar 16 either in slight or extensive ranges of move.- ment of the wheel 12, and at all times respond to the variable ground level of said wheel. It will be understood also that the horizontal portions of the connecting members being locked against endwise movement prevent tilting oi the leveling wheel, and the connected thrasher and harvester sections are further held in flexible relation by stay bars, as 37, 38, in a well known manner.
I claim as my invention:
1. In a machine comprising a harvester and a thrasher, an axle on said thrasher, a connecting member mounted in said axle, a leveling wheel for said harvester having an axle, a connecting member in said harvester axle, and means for securing said members together.
2. In a machine comprising a harvester and thrasher, a swivelled connecting member supported by said thrasher and having an arm, a leveling wheel for said harvester, a swivelled connecting member supported by said wheel and having an arm, and means for securing said arms to permit the movements thereof during the traveling operation of said wheel.
The combination, with a harvesterthrasher comprising a thrasher section and a harvester section, of connecting members associated with said sections, an arm on each 0-1 said members extending at right angles therefrom, and means for pivotally connecting said arms together.
4:. The combination, with a harvesterthrasher comprising a thrasher section and a harvester section, each oi said sections having an axle, of connecting members embodying arms associated with said axles, said arms extending at right angles from said members, means for permitting the variable movement of said members, and means for pivotally connecting said arms to permit the movement of said members in relation to each other.
5. In a machine comprising a harvester and thrasher, a. swivelled controlling member connected to said harvester, an arm on said member arranged at right angles in relation thereto and movable therewith, a swivelled member connected to said thrasher, an arm on said member arranged at right angles thereto and movable therewith, and means for pivotally connecting said arms at their ends.
(3. In a combination harvester-thrasher, the combination of a leveling wheel having an axle, a swivelled connecting member sup ported by said axle, means associated with said axle for preventing endwise movement of said member, and'means for pivotally connecting said member to said thrasher,
7. In a combination harvester-thrasher, the combination of a leveling wheel having an axle, a connecting member supported by said axle and having a neck, a collar about said neck, means for securing said axle and collar to prevent endwise movement of said member, and means for yieldingly connecting said member to said thrasher.
8. In a combination harvester-thrasher, the combination of a leveling wheel having an axle, a rackbar mounted thereon, a connecting member supported by said axle, a thrasher axle, a connecting member mounted in said axle, and means for connecting said members.
9. In a machine comprising a harvester.
