Abstract
Abstract A conveyor belt and system as shown in which an endless belt is secured between two rollers. The belt comprises a web member having an upper frictional surface to which a web liner is secured therebeneath, the web liner being selected from a material having a low coefficient of friction. A planar base member is provided beneath the web and web liner, and a base liner selected from a material having a low coefficient of friction is positioned atop the planar base. The base liner comprises a plurality of laterally spaced longitudinally extending strips positioned to provide a support surface for the web liner. A pair of end rollers are spaced at each end of the conveyor in proximate relationship to the base. The resultant conveyor belt and system provides for a smooth passage of parts for objects atop the frictional surface of the web in the absence of moving parts and required lubrication. One embodiment is shown where the conveyor belt and system is employed in a jogger.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
231 words
A conveyor belt and system comprising in combination, a web member having an upper surface with a high coefficient of friction, a web liner positioned beneath and secured to said web member and in close proximity thereto, said web liner being formed of a material having an under surface with a low coefficient of friction, a planar base member underlining said web member and said web liner, said planar base providing lateral and longitudinal support for said web member and web liner, a plurality of laterally spaces longitudinally extending strips mounted on said planar base and positioned to provide a support surface for accommodating the movement therealong of said web liner, said longitudinally extending strips being formed of a material having a low coefficient of friction, a pair of end rollers at each end of the conveyor for supporting said web member, said planar base and longitudinal strips extending substantially from one of said end rollers to the opposing end roller, whereby said web member is permitted to move between said end rollers and is supported along its longitudinal path of movement by said planar base having said longitudinal strips in touching contact with the under surface of said web liner, the low coefficient of friction as between said web liner and said longitudinal strips providing a smooth path of travel for said web member throughout its longitudinal path of travel.
Claim 2
Dependent Claim
231 words
A conveyor belt and system comprising in combination, a web member having an upper surface with a high coefficient of friction, a web liner positioned beneath and secured to said web member and in close proximity thereto, said web liner being formed of a material having an under surface with a low coefficient of friction, a planar base member underlining said web member and said web liner, said planar base providing lateral and longitudinal support for said web member and web liner, a plurality of laterally spaces longitudinally extending strips mounted on said planar base and positioned to provide a support surface for accommodating the movement therealong of said web liner, said longitudinally extending strips being formed of a material having a low coefficient of friction, a pair of end rollers at each end of the conveyor for supporting said web member, said planar base and longitudinal strips extending substantially from one of said end rollers to the opposing end roller, whereby said web member is permitted to move between said end rollers and is supported along its longitudinal path of movement by said planar base having said longitudinal strips in touching contact with the under surface of said web liner, the low coefficient of friction as between said web liner and said longitudinal strips providing a smooth path of travel for said web member throughout its longitudinal path of travel.
Claim 3
Dependent Claim
97 words
The conveyor belt and system of claim 1 above, which further includes a plurality of socket pockets provided in the under portion of said web member and said web liner at the edges thereof, A plurality of sprockets provided in spaced longitudinal relation along said planar base at the edges thereof and extending therethrough in sequential driving relationship with the socket pocket on said web member, and means for rotating the sprockets whereby the web member can be driven along the top of the planar base smoothly and for a length limited only by the materials employed.
Claim 4
Dependent Claim
59 words
In the conveyor belt and system of claim 1 above, a jogger construction in which said base member is inclined to the horizontal, means for supporting one end of the base in an elevated position, said rollers being journally engaged by the base at its end portions, and hand-hold means extending from the base for engagement by the operator.
Claim 5
Dependent Claim
17 words
In the conveyor belt and system of claim l, an interface coefficient of friction less than 0.10.
Claim 6
Dependent Claim
22 words
In the conveyor belt and system of claim 1, the width of the strips and their lateral spacing being substantially the same.
