Abstract

Abstract A belt-driven live roller conveyor in which the drive area is separated from the conveyor area by a longitudinally extending guide member. A drive belt is disposed above the rollers with its lower drive pass engaging the upper surface of the rollers in the drive area. Spaced pressure members are removably positioned on the belt in the drive area, these members comprising a pair of spaced rolls riding on the drive belt pass and a frame supporting the rolls in spaced relationship so that they bridge at least one conveyor roller. Means are also provided for preventing the pressure members from traveling with the belt.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 134 words
A live roller conveyor including a plurality of rollers comprising main portions forming a load conveying path and end portions forming a drive path; a drive belt having a drive pass engaging the upper surfaces of the portions of said rollers forming said drive path; at least one pressure member for effecting driving engagement of said drive pass with a plurality of adjacent rollers, said pressure member being freely riding, and manually removable, and comprising a frame and spaced rolls supported by said frame for engaging the upper surface of said belt drive pass, said rolls being spaced to bridge at least one roller; spaced guide means for laterally positioning said pressure member on said belt; and stop means engaging said pressure member frame for preventing said pressure member from traveling with said belt.
Claim 2
Dependent Claim 134 words
A live roller conveyor including a plurality of rollers comprising main portions forming a load conveying path and end portions forming a drive path; a drive belt having a drive pass engaging the upper surfaces of the portions of said rollers forming said drive path; at least one pressure member for effecting driving engagement of said drive pass with a plurality of adjacent rollers, said pressure member being freely riding, and manually removable, and comprising a frame and spaced rolls supported by said frame for engaging the upper surface of said belt drive pass, said rolls being spaced to bridge at least one roller; spaced guide means for laterally positioning said pressure member on said belt; and stop means engaging said pressure member frame for preventing said pressure member from traveling with said belt.
Claim 3
Dependent Claim 14 words
A conveyor according to claim 1 in which said rolls bridge two adjacent rollers.
Claim 4
Dependent Claim 123 words
A live roller conveyor comprising a series of spaced, parallel, laterally disposed rollers forming a planar surface; a drive belt positioned above said rollers with its lower drive pass engaging the upper surfaces of said rollers; first and second longitudinally extending members on opposite edges of the drive belt defining a channel; independent removable pressure members freely riding on said drive pass within said channel and laterally positioned by said members and comprising spaced rolls riding on said drive pass and a frame supporting said rolls in spaced relationship sufficient to bridge at least one roller; and means carried by one of said members for engagement by said frames of said pressure members to prevent said pressure members from traveling with said belt.
Claim 5
Dependent Claim 123 words
A live roller conveyor comprising a series of spaced, parallel, laterally disposed rollers forming a planar surface; a drive belt positioned above said rollers with its lower drive pass engaging the upper surfaces of said rollers; first and second longitudinally extending members on opposite edges of the drive belt defining a channel; independent removable pressure members freely riding on said drive pass within said channel and laterally positioned by said members and comprising spaced rolls riding on said drive pass and a frame supporting said rolls in spaced relationship sufficient to bridge at least one roller; and means carried by one of said members for engagement by said frames of said pressure members to prevent said pressure members from traveling with said belt.
Claim 6
Dependent Claim 25 words
A conveyor according to claim 3 in which said rolls bridge at least two rollers and each roll engages said belt between two adjacent rollers.
Claim 7
Dependent Claim 23 words
A conveyor according to claim 3 in which some of said pressure members include means for supporting the return pass of said belt.
