Abstract
Abstract The invention pertains to improvements in conveyors for carrying parts such as automobile valves. The invention eliminates the need for any special entrance or feeding apparatus to the conveyor. The conveyor configuration itself and the configuration of the parts provide for the proper acceptance of the parts into the conveyor. The invention also provides for a torque limiting drive incorporated with the conveyor such that in the event of a jam the conveyor automatically oscillates back and forth until the jammed part is released.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
60 words
A collecting and distributing conveyor system comprising, an endless linear conveyor, part entrance means to said conveyor, sequential part guiding means leading to said part entrance means, a plurality of part accepting means on said conveyor, means attached to said conveyor between said part accepting means to prevent parts from entering said conveyor, and part exit means from said conveyor.
Claim 2
Dependent Claim
60 words
A collecting and distributing conveyor system comprising, an endless linear conveyor, part entrance means to said conveyor, sequential part guiding means leading to said part entrance means, a plurality of part accepting means on said conveyor, means attached to said conveyor between said part accepting means to prevent parts from entering said conveyor, and part exit means from said conveyor.
Claim 3
Dependent Claim
22 words
The conveyor system as set forth in claim 1 including part guiding rods substantially parallel to a portion of said endless conveyor.
Claim 4
Dependent Claim
17 words
