Abstract
A conveyor has a drive wheel which is driven from a driveshaft and which moves into and out of driving engagement. In the preferred embodiment, there is a drive gear mounted on the drive shaft, and the drive gear drives a drive wheel, which is mounted on a drive wheel mounting frame that pivots about the axis of the drive shaft, so that the drive wheel is constantly driven from the driveshaft and pivots into and out of driving engagement with the conveyor roller.
Claims21
A conveyor, comprising:
- a conveyor frame;
- a plurality of conveyor rollers mounted on said conveyor frame;
- a drive shaft extending along said conveyor frame;
- at least one drive wheel rotatable about its axis, said drive wheel being driven from said drive shaft;
- a drive wheel mounting frame on which is mounted said drive wheel, said drive wheel mounting frame being movable relative to said conveyor frame, such that, when said mounting frame is moved to a first position, said drive wheel is in driving contact with at least one of said conveyor rollers, and, when said mounting frame is moved to a second position, said drive wheel is out of driving contact with said at least one of said conveyor rollers.
2 more elements
A conveyor, comprising:
- a conveyor frame;
- a drive shaft extending along said conveyor frame;
- at least one drive wheel rotatable about an axis which is substantially perpendicular to the axis of the drive shaft, said drive wheel being driven from said drive shaft;
- a drive wheel mounting frame on which is mounted said drive wheel, said drive wheel mounting frame being movable relative to said conveyor frame, such that, when said mounting frame is moved upward, said drive wheel is in driving position, and, when said mounting frame is moved downward, said drive wheel is out of driving position.
1 more element
A conveyor, comprising:
- a conveyor frame;
- a drive shaft extending along said conveyor frame;
- at least one drive gear mounted on said drive shaft for rotation with said drive shaft;
- a bracket mounted on said conveyor frame;
- a drive wheel mounting frame pivotably supported from said bracket so as to pivot about the axis of said drive shaft;
- a drive wheel and driven gear mounted on said drive wheel mounting frame such that, when said driven gear rotates, said drive wheel rotates, said driven gear being continuously meshed with said drive gear, such that, whenever said drive shaft rotates, it drives said drive gear, which drives said driven gear, which drives said drive wheel, and, such that, when said drive wheel mounting frame is pivoted to one position, said drive wheel is in driving position, and, when said drive wheel mounting frame is pivoted to a second position, said drive wheel is out of driving position.
3 more elements
In a conveyor, comprising:
- a conveyor frame
- a drive shaft extending along said conveyor frame;
- a plurality of rollers mounted on said conveyor frame;
- and
- means for driving said rollers from said drive shaft;
- characterized in that said means for driving said rollers includes:
- a drive wheel mounted as to be pivotable about the axis of said drive shaft, such in one position, said drive wheel is in driving engagement with at least one of said rollers, and, in another position said drive wheel is out of driving engagement with said and at least one of said rollers, said drive wheel being driven from said drive shaft.
