Abstract
Abstract A series of steps are performed at a plurality of stations on a component as it is automatically transferred from one station to the next during a manufacturing operation. Means and methods for measuring and recording the time cycles for each of the steps are provided. The recorded times cycles may then be compared with predetermined standards to determine the location of any faulty operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
In combination with a conveyor for transporting mechanical components through a plurality of stations for performing a series of steps at each station in the manufacturing of said component, means for monitoring and recording data relating to said series of steps at each of said stations comprising: (a) electrical means at a first station for starting and stopping each of said series of steps and causing the operation of the next of said series of steps until all the steps at said first station have been completed; (b) second electrical means for sensing the last of the series steps of said first station and causing said component to be sequentially transferred by said conveyor to a next station; (c) means for measuring and recording the cycle times of each of said series of steps at said plurality of stations, (d) second means for measuring and recording the total time of the series of steps at each of said plurality of stations, and (e) said series of steps including a plurality of actuating mechanical elements responsive to said electrical means to sequentially perform said series of steps.
Claim 2
Dependent Claim
186 words
In combination with a conveyor for transporting mechanical components through a plurality of stations for performing a series of steps at each station in the manufacturing of said component, means for monitoring and recording data relating to said series of steps at each of said stations comprising: (a) electrical means at a first station for starting and stopping each of said series of steps and causing the operation of the next of said series of steps until all the steps at said first station have been completed; (b) second electrical means for sensing the last of the series steps of said first station and causing said component to be sequentially transferred by said conveyor to a next station; (c) means for measuring and recording the cycle times of each of said series of steps at said plurality of stations, (d) second means for measuring and recording the total time of the series of steps at each of said plurality of stations, and (e) said series of steps including a plurality of actuating mechanical elements responsive to said electrical means to sequentially perform said series of steps.
Claim 3
Dependent Claim
46 words
A combination as set forth in claim 1 wherein the start and completion of each of said series of steps cause electrical signals to be generated to start and stop a first timing circuit to measure the time cycle of each of said series of steps.
Claim 4
Dependent Claim
60 words
A combination as set forth in claim 2 wherein the start and completion of all of said series of steps at each of said plurality of stations cause second electrical signals to be generated to start and stop a second timing circuit to measure the total time cycle of a series of steps at each of said plurality of stations.
Claim 5
Dependent Claim
29 words
A combination as set forth in claim 3 wherein means are provided to compare the time cycle of each of said series of steps with a predetermined time cycle.
Claim 6
Dependent Claim
35 words
A combination as set forth in claim 4 wherein second means are provided to compare the total time cycle of a series of steps at each of said stations with a predetermined total time cycle.
Claim 7
Dependent Claim
34 words
A combination as set forth in claim 5 wherein means are provided to discontinue said manufacturing of said component when said total time cycle exceeds a predetermined percentage of said predetermined total time cycle.
Claim 8
Dependent Claim
33 words
The combination as set forth in claim 6 wherein means are for recording data relating to said time cycle, said total time cycle, said predetermined time cycle and said predetermined total time cycle.
Claim 9
Dependent Claim
23 words
A combination as set forth in claim 1 wherein means are provided for indicating a malfunction in any of said series of steps.
