Abstract

Abstract A hay rolling machine adapted to form rolls of hay from a swath or windrow thereof in partially cured condition while lying on a field to form a roll of hay of substanial size and weight as the machine is moved along the field by a tractor or otherwise. The machine as provided with roll pickup means respectively adjacent the forward and rearward ends of the machine and including sets of fingers respectively movable toward each other in a manner to raise a roll of hay a sufficient distance to enable the machine to move the roll of hay while the roll is suspended upon said fingers.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 174 words
A machine to form rolls of hay and the like from a swath or windrow thereof lying in a field and comprising in combination, a base frame, wheels mounted at opposite sides of said frame to render the same mobile to move along a field, hay pickup and rolling means on said frame adjacent the normally rear end thereof movably supported and engagable with the leading end of a swath or windrow of partially cured hay and the like and operable to roll the same along a field surface in the direction of movement of the machine to form a coreless coiled roll of said hay and the like, and roll pickup means carried by said frame comprising a plurality of elements movable toward each other to engage a roll of hay of predetermined size at circumferentially spaced locations below the axis thereof and thereby raise the same above the surface of a field a sufficient distance to clear the field and permit transportation of the roll to a desired location by said machine.
Claim 2
Dependent Claim 174 words
A machine to form rolls of hay and the like from a swath or windrow thereof lying in a field and comprising in combination, a base frame, wheels mounted at opposite sides of said frame to render the same mobile to move along a field, hay pickup and rolling means on said frame adjacent the normally rear end thereof movably supported and engagable with the leading end of a swath or windrow of partially cured hay and the like and operable to roll the same along a field surface in the direction of movement of the machine to form a coreless coiled roll of said hay and the like, and roll pickup means carried by said frame comprising a plurality of elements movable toward each other to engage a roll of hay of predetermined size at circumferentially spaced locations below the axis thereof and thereby raise the same above the surface of a field a sufficient distance to clear the field and permit transportation of the roll to a desired location by said machine.
Claim 3
Dependent Claim 16 words
The hay rolling machine according to claim 1 in which said cooperative lifting means are tong-like.
Claim 4
Dependent Claim 32 words
The hay rolling machine according to claim 2 in which one of said lifting elements is adjacent the forward end of the machine and the other is adjacent the rearward end thereof.
Claim 5
Dependent Claim 55 words
The hay rolling machine according to claim 1 in which said roll pickup means comprise a set of transversely spaced fingers mounted forwardly in said frame and a set of transversely spaced fingers mounted rearwardly in said frame, one of said sets being movable toward the other to raise said roll of hay as aforesaid.
Claim 6
Dependent Claim 36 words
The hay rolling machine according to claim 4 in which said forwardly mounted set of fingers extend downward and rearward and said rearwardly mounted set extend downward and at least the lowermost portions thereof extend forwardly.
Claim 7
Dependent Claim 66 words
The hay rolling machine according to claim 5 in which said forwardly mounted set of fingers are fixed to a transverse shaft on said frame, and said machine further including means to adjust the angle at which said set of fingers extend relative to the surface of a field upon which hay is being rolled to facilitate the picking up of rolls of various diameters efficiently.
Claim 8
Dependent Claim 107 words
The hay rolling machine according to claim 5 firtjer including side frame members extending upwardly from opposite sides of said base frame, and a shaft extending across said machine between the upper portions of said side frame members, said rearwardly mounted fingers being supported at one end by said shaft and extending downward therefrom and adapted to be moved pivotally upon the axis of said shaft to move the lower portions of said fingers forwardly to engage a roll of hay and roll the same onto said downward and rearwardly extending forwardly mounted fingers to elevate said roll sufficiently at least to be clear of the field.
Claim 9
Dependent Claim 41 words
The hay rolling machine according to claim 7 further including power means interconnected to said rearwardly mounted fingers and operable to move the same simultaneously between rearward idle position and forward operative position to elevate a roll of hay as aforesaid.
Claim 10
Dependent Claim 47 words
The hay rolling machine according to claim 8 further including supporting means rotatable upon said shaft and said rearwardly mounted fingers being commonly connected thereto, and said power means comprising a fluid operated cylinder and piston unit interconnected commonly to said fingers to operate the same simultaneously.
Claim 11
Dependent Claim 107 words
The hay rolling machine according to claim 4 further including side frame members extending upwardly from opposite sides of said base frame, auxiliary frame means extending downwardly from the upper portions of said side frame members and pivotally movable rearwardly relative thereto, said rearwardly mounted fingers being movable pivotally about and extending downward from transverse axis extending between the upper portions of said side frame members and power means connected between said fingers and said auxiliary frame means and operable to move the lower ends of said fingers toward said forwardly mounted fingers to raise a roll of hay above the surface of a field as aforesaid.
Claim 12
Dependent Claim 146 words
The hay rolling machine according to claim 10 in which said base frame is open at the rear end and said auxiliary frame means comprises a pair of similar frame members pivotally interconnected at the upper ends thereto to the upper portions of said side frame members, and cross members extending therebetween to space said similar frame members together, said hay pickup and rolling means being supported by said auxiliary frame means, and additional power means at opposite sides of said machine and connected to said auxiliary frame means and operable to pivotally elevate the same upwardly and rearwardly adequately to raise said hay rolling means and rearwardly mounted fingers supported thereby to a discharge position to clear a roll of hay when the diameter thereof has increased to a desired extent and is to be discharged through the open rear end of said base frame.
Claim 13
Dependent Claim 87 words
The hay rolling machine according to claim 11 in which said similar frame members of said auxiliary frame are each angular in shape and comprise normally upper and lower sections disposed at a wide angle to each other and having the apex thereof extending rearwardly, whereby when said frame is raised to discharge position, the upper sections of said members extend upwardly and rearwardly to dispose said hay pickup and rolling means and rearward fingers substantially horizontal and thus adequately clear the roll of hay being discharged.
Claim 14
Dependent Claim 92 words
The hay rolling machine according to claim 11 further including drive means for said hay pickup and rolling means connected to at least one of said wheels on said base frame to drive the same when said machine is moved along a field, and clutch means included interconnected between said hay pickup and rolling means and said wheel, said clutch means being operable to disconnect the same and thereby render said hay pickup and rolling means idle when said auxiliary frame is elevated to permit discharge of a roll of hay therebeneath.
