Abstract
Abstract A spinning machine with a plurality of spinning locations or stations is equipped with automatic or semi-automatic spool-changing mechanisms. The machine also has a servicing device, designed for travel along the machine and for repairing thread breakages at some particular spinning location. The presence of this servicing device or carriage at a spinning location would interfere with the operation of the spool-changing mechanism. A controller delivers signals to an appropriate receiver in the servicing device and causes it to depart to a neutral zone at the end of the machine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
74 words
In a spinning machine which includes a plurality of spinning locations and including at least one servicing device capable of movement along said spinning locations, the improvement comprising: control means for sending control signals from said spinning machine to said servicing device for effecting the movement of the servicing device including optionally servicing said locations during the movement; whereby the operation of said servicing device is dependent on operational states of said spinning machine.
Claim 2
Dependent Claim
74 words
In a spinning machine which includes a plurality of spinning locations and including at least one servicing device capable of movement along said spinning locations, the improvement comprising: control means for sending control signals from said spinning machine to said servicing device for effecting the movement of the servicing device including optionally servicing said locations during the movement; whereby the operation of said servicing device is dependent on operational states of said spinning machine.
Claim 3
Dependent Claim
54 words
An improved spinning machine as defined in claim 1, wherein said control means include signal generating means for sending signals for causing the departure of said servicing device from the vicinity of said spinning locations whereby the servicing device moves without further servicing the spinning locations to a rest location where it remains stationary.
Claim 4
Dependent Claim
59 words
A spinning machine as defined in claim 2, the improvement further comprising motor means located in said servicing device, for providing motion at a speed greater than a normal speed and wherein said control means are capable of sending signals which activate said motor means to provide said greater speed for departing from the vicinity of said spinning locations.
Claim 5
Dependent Claim
31 words
A spinning machine as defined in claim 1, wherein said control means includes signal generating means for sending said signals in timed manner relative to operational events in said spinning machine.
Claim 6
Dependent Claim
62 words
A spinning machine as defined in claim 1, the improvement further comprising: a contact rail, affixed to said spinning machine and substantially extending along said spinning locations and a sliding electrical contact, attached to said servicing device to provide sliding electrical contact with said contact rail; whereby signals from said control means are transmitted to said servicing device through said sliding contact.
Claim 7
Dependent Claim
30 words
A spinning machine as defined in claim 1, wherein said control means includes means for generating signals with electrical potentials whose magnitudes are variable with time in a predetermined manner.
