Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A conveyor and discharge system for a sorting system, comprising: a motor unit at a discharge station along a path; and a carriage movable along the path having a rotatable belt for conveying an item on the carriage as the carriage moves along the path and link means linking the rotatable belt to the motor unit when the carriage has moved along the path to the discharge station for revolving the rotatable belt with the motor unit, wherein: the motor unit comprises a motor and rotation means rotated by the motor; the carriage further comprises a roll on which the rotatable belt is mounted for revolving thereby; and the link means on the carriage comprises a rotatable shaft, gears respectively at one end of the shaft and roll rotatably engaging the shaft with the roll, a wheel on the other end of the shaft for frictionally engaging the rotation means for rotation thereby, whereby to revolve the belt, and stop means for avoiding rotation of the shaft and, thereby, the belt when the wheel is not engaged with the rotation means.
Claim 2
Dependent Claim
181 words
A conveyor and discharge system for a sorting system, comprising: a motor unit at a discharge station along a path; and a carriage movable along the path having a rotatable belt for conveying an item on the carriage as the carriage moves along the path and link means linking the rotatable belt to the motor unit when the carriage has moved along the path to the discharge station for revolving the rotatable belt with the motor unit, wherein: the motor unit comprises a motor and rotation means rotated by the motor; the carriage further comprises a roll on which the rotatable belt is mounted for revolving thereby; and the link means on the carriage comprises a rotatable shaft, gears respectively at one end of the shaft and roll rotatably engaging the shaft with the roll, a wheel on the other end of the shaft for frictionally engaging the rotation means for rotation thereby, whereby to revolve the belt, and stop means for avoiding rotation of the shaft and, thereby, the belt when the wheel is not engaged with the rotation means.
Claim 3
Dependent Claim
49 words
The conveyor and discharge system of claim 1, wherein the stop means comprises a stop on the carriage engagable with the gear on the shaft for preventing rotation thereof and a bracket pivotably mounting the shaft on the carriage for disengaging the gear on the shaft from the stop.
Claim 4
Dependent Claim
24 words
The conveyor and discharge system of claim 1 wherein the rotation means comprises a pair of rotatable belts for seizing the wheel between them.
Claim 5
Dependent Claim
24 words
The conveyor and discharge system of claim 2, wherein the rotation means comprises a pair of rotatable belts for seizing the wheel between them.
Claim 6
Dependent Claim
34 words
The conveyor and discharge system of claim 1, and further comprising actuator means connected to the rotation means for moving the rotation means out of a position for the frictional engagement of the wheel.
Claim 7
Dependent Claim
34 words
The conveyor and discharge system of claim 2, and further comprising actuator means connected to the rotation means for moving the rotation means out of a position for the frictional engagement of the wheel.
Claim 8
Dependent Claim
34 words
The conveyor and discharge system of claim 3, and further comprising actuator means connected to the rotation means for moving the rotation means out of a position for the frictional engagement of the wheel.
Claim 9
Dependent Claim
34 words
The conveyor and discharge system of claim 4, and further comprising actuator means connected to the rotation means for moving the rotation means out of a position for the frictional engagement of the wheel.
