Abstract
Abstract A flexible link connecting structure as for a conveyor such as is used with a potato combine in which the links comprise parallel rods and the connecting structure consists of overlapping pairs of connecting members each formed as a pair of substantially cylindrical portions of a rubber composition material hinged in closely spaced relation by a flexible web portion, said cylindrical portions each having an axial bore of a lesser diameter than that of each of said rods whereby end portions of said rods are disposed within said bores in a nonrotating pressure fit and a plate spring member is embedded in each of said connecting members disposed through each of said web portions and having end portions thereof spaced from and substantially encircling each of said bores.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
An endless conveyor structure having in combination sprockets comprising driving means, a conveyor comprising parallel spaced rods engaged and driven by said sprockets, a connecting member for each adjacent pair of end portions of said rods, each of said connecting members comprising a pair of spaced body portions, each of said body portions having a bore therethrough of lesser diameter than the diameters of said rods, said body portions being sufficiently resilient to receive said rod end portions within said bores for a pressure-tight non-rotative fit therein, a flexible web integral with said body portions forming a hinge therebetween, and resilient reinforcing means embodied within said connecting member.
Claim 2
Dependent Claim
108 words
An endless conveyor structure having in combination sprockets comprising driving means, a conveyor comprising parallel spaced rods engaged and driven by said sprockets, a connecting member for each adjacent pair of end portions of said rods, each of said connecting members comprising a pair of spaced body portions, each of said body portions having a bore therethrough of lesser diameter than the diameters of said rods, said body portions being sufficiently resilient to receive said rod end portions within said bores for a pressure-tight non-rotative fit therein, a flexible web integral with said body portions forming a hinge therebetween, and resilient reinforcing means embodied within said connecting member.
Claim 3
Dependent Claim
18 words
The structure set forth in claim 1, wherein said connecting member comprises a plurality of said body portions.
Claim 4
Dependent Claim
29 words
The structure set forth in claim 1, wherein portions of said resilient means at least partially encircle the bores of each of said body portions in spaced relation thereto.
Claim 5
Dependent Claim
29 words
The structure set forth in claim 2, wherein portions of said resilient means at least partially encircle the bores of each of said body portions in spaced relation thereto.
Claim 6
Dependent Claim
16 words

Claim 7
Dependent Claim
48 words
The structure set forth in claim 1, wherein said connecting member comprises a plurality of said body portions, said web being integral with adjacent pairs of said body portions, and said resilient means having connected portions at least partially encircling the bore of each of said body portions.
Claim 8
Dependent Claim
74 words
A sprocket driven conveyor structure having in combination parallel rods of uniform diameter in spaced relation, a connecting member between adjacent end portions of said rods, each of said connecting members comprising spaced body portions, a bore through each of said body portions having a diameter less than the diameters of said rods, a flexible web integral with said body portions forming a hinge therebetween, and resilient reinforcing means embodied within said connecting member.
Claim 9
Dependent Claim
74 words
A sprocket driven conveyor structure having in combination parallel rods of uniform diameter in spaced relation, a connecting member between adjacent end portions of said rods, each of said connecting members comprising spaced body portions, a bore through each of said body portions having a diameter less than the diameters of said rods, a flexible web integral with said body portions forming a hinge therebetween, and resilient reinforcing means embodied within said connecting member.
Claim 10
Dependent Claim
16 words
The structure set forth in claim 7, wherein said resilient means comprises a spring plate member.
Claim 11
Dependent Claim
31 words
The structure set forth in claim 8, wherein connected portions of said spring plate member at least partially encircle each of said bores of said body portions in spaced relation thereto.
