Abstract
Abstract In a baler having a series of belt rollers that are supported by upright panels in a way to present normally uninterrupted, continuous spans across and between the panels, a set of endless belts may be installed on the machine, notwithstanding the presence of the panels at opposite ends of the rollers, by temporarily interrupting each span and slipping the new belts through the interruption. Clearances for belt replacement are presented by removing spacers from the rollers. The spacers are disposed between the proximate ends of roller sections, each pair of sections having a releasable coupling provided with parts which receive the spacers therebetween. The clearances so presented are preferably quite narrow, sufficient only that the belts may be passed through the clearances in an edgewise direction.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
103 words
In a farm implement for making round bales from crop material: a pair of horizontally spaced uprights; means holding said uprights a fixed distance apart; a plurality of transverse, horizontal elements rotatably supported by the uprights and arranged in mutually spaced parallelism, each of said elements being coupled with said uprights in a manner to present a normally uninterrupted, continuous span across and between the uprights; a series of endless, flexible members trained around the elements in engagement therewith; and means associated with each element for temporarily interrupting said span and presenting a clearance for the members to permit replacement of the latter.
Claim 2
Dependent Claim
103 words
In a farm implement for making round bales from crop material: a pair of horizontally spaced uprights; means holding said uprights a fixed distance apart; a plurality of transverse, horizontal elements rotatably supported by the uprights and arranged in mutually spaced parallelism, each of said elements being coupled with said uprights in a manner to present a normally uninterrupted, continuous span across and between the uprights; a series of endless, flexible members trained around the elements in engagement therewith; and means associated with each element for temporarily interrupting said span and presenting a clearance for the members to permit replacement of the latter.
Claim 3
Dependent Claim
16 words
The invention of claim 1, said span interrupting means being intermediate the ends of the elements.
Claim 4
Dependent Claim
13 words
The invention of claim 1, said span interrupting means comprising a removable spacer.
Claim 5
Dependent Claim
25 words
The invention of claim 3, said members being flat belts, each spacer being a disc having a thickness greater than the thickness of the belts.
Claim 6
Dependent Claim
16 words
The invention of claim 3, the spacers being releasably attached to the elements for rotation therewith.
Claim 7
Dependent Claim
43 words
The invention of claim 3, each element being provided with a pair of generally collinear sections having their proximal ends in spaced relationship; and a releasable coupling between the sections of each roller respectively, said spacers being removable upon release of the couplings.
Claim 8
Dependent Claim
29 words
The invention of claim 6, each coupling having a pair of releasably interconnected components, each component being secured to a corresponding component, the spacers being disposed between said components.
Claim 9
Dependent Claim
28 words
The invention of claim 7, each coupling having releasable fastening means interconnecting the components thereof, said fastening means normally holding the spacers against removal from between the components.
Claim 10
Dependent Claim
23 words
The invention of claim 8, said components extending radially outwardly from the sections, said fastening means extending through the components and the spacers.
Claim 11
Dependent Claim
22 words
The invention of claim 9, the components being continuous flanges surrounding the sections, said fastening means clamping the spacers between the flanges.
Claim 12
Dependent Claim
163 words
In a farm implement for making round bales from crop materials, a pair of upright walls maintained in fixedly spaced apart relationship; a plurality of rotatable, normally horizontal rollers supported between said walls and arranged in spaced parallelism a series of flat, endless, flexible belts trained around the rollers in engagement therewith, each roller being provided with a pair of collinear sections having their proximal ends in spaced relationship; and a releasable coupling for the sections of each roller respectively, each coupling including: a continuous, radial flange surrounding each section respectively and rigidly secured thereto adjacent said end thereof, a spacer between the flanges, and an annular row of spaced bolts extending through the flanges and the spacer for clamping the spacer between the flanges, said bolts being removable from the flanges and the spacers for release and removal of the latter from between the flanges to permit replacement of the belts through the spaces between the sections of all of the rollers.
Claim 13
Dependent Claim
163 words
In a farm implement for making round bales from crop materials, a pair of upright walls maintained in fixedly spaced apart relationship; a plurality of rotatable, normally horizontal rollers supported between said walls and arranged in spaced parallelism a series of flat, endless, flexible belts trained around the rollers in engagement therewith, each roller being provided with a pair of collinear sections having their proximal ends in spaced relationship; and a releasable coupling for the sections of each roller respectively, each coupling including: a continuous, radial flange surrounding each section respectively and rigidly secured thereto adjacent said end thereof, a spacer between the flanges, and an annular row of spaced bolts extending through the flanges and the spacer for clamping the spacer between the flanges, said bolts being removable from the flanges and the spacers for release and removal of the latter from between the flanges to permit replacement of the belts through the spaces between the sections of all of the rollers.
Claim 14
Dependent Claim
83 words
In a method of installing endless, flexible belts on a farm implement for making round bales from crop materials wherein the belts, when in place, are trained around a plurality of horizontal rollers carried between a pair of fixedly spaced apart uprights in such a manner as to define normally uninterrupted, continuous spans across the uprights, the steps of: interrupting each span by opening a space therein; slipping the belts through the spaces; and discontinuing interruption of the spans by reclosing the spaces.
Claim 15
Dependent Claim
83 words
In a method of installing endless, flexible belts on a farm implement for making round bales from crop materials wherein the belts, when in place, are trained around a plurality of horizontal rollers carried between a pair of fixedly spaced apart uprights in such a manner as to define normally uninterrupted, continuous spans across the uprights, the steps of: interrupting each span by opening a space therein; slipping the belts through the spaces; and discontinuing interruption of the spans by reclosing the spaces.
Claim 16
Dependent Claim
16 words
The method of claim 12, wherein said space is opened intermediate the ends of the rollers.
Claim 17
Dependent Claim
18 words
The method of claim 13, wherein said space is opened by removing a spacer from each roller respectively.
Claim 18
Dependent Claim
82 words
In a method of installing endless, flexible belts on a farm implement for making round bales from crop materials wherein the belts when installed, are trained around a plurality of spaced, horizontal, parallel, rotatable rollers carried by and normally uninterruptedly spanning a pair of mutually and fixedly spaced apart, upright panels, each roller including a removable spacer, the steps of: removing said spacers to provide a belt-clearing space for each roller respectively; threading each belt through the spaces; and replacing said spacers.
